Boxed Warning

Warning: Lactic Acidosis

  • Post-marketing cases of metformin-associated lactic acidosis have resulted in death, hypothermia, hypotension, and resistant bradyarrhythmias. The onset of metformin-associated lactic acidosis is often subtle, accompanied only by nonspecific symptoms such as malaise, myalgias, respiratory distress, somnolence, and abdominal pain. Metformin-associated lactic acidosis was characterized by elevated blood lactate levels (> 5 mmol/Liter), anion gap acidosis (without evidence of ketonuria or ketonemia), an increased lactate/pyruvate ratio; and metformin plasma levels generally >5 mcg/mL [see Warnings and Precautions (5.1)] .
  • Risk factors for metformin-associated lactic acidosis include renal impairment, concomitant use of certain drugs (e.g., carbonic anhydrase inhibitors such as topiramate), age 65 years old or greater, having a radiological study with contrast, surgery and other procedures, hypoxic states (e.g., acute congestive heart failure), excessive alcohol intake, and hepatic impairment [see Warnings and Precautions (5.1)] .
  • Steps to reduce the risk of and manage metformin-associated lactic acidosis in these high risk groups are provided in the full prescribing information [see Dosage and Administration (2.2, 2.3), Contraindications (4), Warnings and Precautions (5.1), Drug Interactions (7), and Use in Specific Populations (8.6, 8.7)] .
  • If metformin-associated lactic acidosis is suspected, immediately discontinue INVOKAMET or INVOKAMET XR and institute general supportive measures in a hospital setting. Prompt hemodialysis is recommended [see Warnings and Precautions (5.1)] .

5 Warnings And Precautions


  • Diabetic Ketoacidosis in Patients with Type 1 Diabetes Mellitus and Other Ketoacidosis: Consider ketone monitoring in patients at risk for ketoacidosis, as indicated. Assess for ketoacidosis regardless of presenting blood glucose levels and discontinue INVOKAMET or INVOKAMET XR if ketoacidosis is suspected. Monitor patients for resolution of ketoacidosis before restarting ( 5.2)
  • Lower Limb Amputation: Monitor patients for infection or ulcers of lower limb and discontinue if these occur ( 5.3)

  • Urosepsis and pyelonephritis: Evaluate patients for signs and symptoms of urinary tract infections and treat promptly, if indicated ( 5.5)
  • Hypoglycemia: Consider a lower dose of insulin or insulin secretagogue to reduce the risk of hypoglycemia when used in combination ( 5.6)
  • Necrotizing fasciitis of the perineum (Fournier's gangrene): Serious, life-threatening cases have occurred in both females and males. Assess patients presenting with pain or tenderness, erythema, or swelling in the genital or perineal area, along with fever or malaise. If suspected, institute prompt treatment ( 5.7)
  • Genital mycotic infections: Monitor and treat if indicated ( 5.8)
  • Hypersensitivity reactions: Discontinue and monitor until signs and symptoms resolve ( 5.9)
  • Bone fracture: Consider factors that contribute to fracture risk before initiating INVOKAMET or INVOKAMET XR ( 5.10)
  • Vitamin B 12deficiency : Metformin HCl may lower vitamin B 12levels. Measure hematological parameters annually and vitamin B 12at 2- to 3-year intervals and manage any abnormalities ( 5.11)

5.1 Lactic Acidosis


There have been post-marketing cases of metformin-associated lactic acidosis, including fatal cases. These cases had a subtle onset and were accompanied by nonspecific symptoms such as malaise, myalgias, abdominal pain, respiratory distress, or increased somnolence; however, hypothermia, hypotension and resistant bradyarrhythmias have occurred with severe acidosis. Metformin-associated lactic acidosis was characterized by elevated blood lactate concentrations (>5 mmol/Liter), anion gap acidosis (without evidence of ketonuria or ketonemia), and an increased lactate:pyruvate ratio; metformin plasma levels generally >5 mcg/mL. Metformin decreases liver uptake of lactate increasing lactate blood levels which may increase the risk of lactic acidosis, especially in patients at risk.

If metformin-associated lactic acidosis is suspected, general supportive measures should be instituted promptly in a hospital setting, along with immediate discontinuation of INVOKAMET or INVOKAMET XR. In INVOKAMET or INVOKAMET XR-treated patients with a diagnosis or strong suspicion of lactic acidosis, prompt hemodialysis is recommended to correct the acidosis and remove accumulated metformin (metformin is dialyzable, with a clearance of up to 170 mL/min under good hemodynamic conditions). Hemodialysis has often resulted in reversal of symptoms and recovery.

Educate patients and their families about the symptoms of lactic acidosis and if these symptoms occur instruct them to discontinue INVOKAMET or INVOKAMET XR and report these symptoms to their healthcare provider.

For each of the known and possible risk factors for metformin-associated lactic acidosis, recommendations to reduce the risk of and manage metformin-associated lactic acidosis are provided below:


Renal Impairment:The postmarketing metformin-associated lactic acidosis cases primarily occurred in patients with significant renal impairment. The risk of metformin accumulation and metformin-associated lactic acidosis increases with the severity of renal impairment because metformin is substantially excreted by the kidney. Clinical recommendations based upon the patient's renal function include [see Dosage and Administration (2.4)and Clinical Pharmacology (12.3)].
  • Before initiating INVOKAMET or INVOKAMET XR, obtain an estimated glomerular filtration rate (eGFR).
  • INVOKAMET or INVOKAMET XR is contraindicated in patients with an eGFR less than 30 mL/min/1.73 m 2 [see Contraindications (4)] .
  • Obtain an eGFR at least annually in all patients taking INVOKAMET or INVOKAMET XR. In patients at increased risk for the development of renal impairment (e.g., the elderly), renal function should be assessed more frequently.


Drug Interactions:The concomitant use of INVOKAMET or INVOKAMET XR with specific drugs may increase the risk of metformin-associated lactic acidosis: those that impair renal function, result in significant hemodynamic change, interfere with acid-base balance or increase metformin accumulation (e.g. cationic drugs) [see Drug Interactions (7)]. Therefore, consider more frequent monitoring of patients.


Age 65 or Greater:The risk of metformin-associated lactic acidosis increases with the patient's age because elderly patients have a greater likelihood of having hepatic, renal, or cardiac impairment than younger patients. Assess renal function more frequently in elderly patients [ see Use in Specific Populations (8.5)].


Radiological Studies with Contrast:Administration of intravascular iodinated contrast agents in metformin-treated patients has led to an acute decrease in renal function and the occurrence of lactic acidosis. Stop INVOKAMET or INVOKAMET XR at the time of, or prior to, an iodinated contrast imaging procedure in patients with an eGFR less than 60 mL/min/1.73 m 2; in patients with a history of hepatic impairment, alcoholism, or heart failure; or in patients who will be administered intra-arterial iodinated contrast. Re-evaluate eGFR 48 hours after the imaging procedure, and restart INVOKAMET or INVOKAMET XR if renal function is stable.


Surgery and Other Procedures:Withholding of food and fluids during surgical or other procedures may increase the risk for volume depletion, hypotension and renal impairment.

INVOKAMET or INVOKAMET XR should be temporarily discontinued while patients have restricted food and fluid intake.


Hypoxic States:Several of the postmarketing cases of metformin-associated lactic acidosis occurred in the setting of acute congestive heart failure (particularly when accompanied by hypoperfusion and hypoxemia). Cardiovascular collapse (shock), acute myocardial infarction, sepsis, and other conditions associated with hypoxemia have been associated with lactic acidosis and may also cause pre-renal azotemia. When such events occur, discontinue INVOKAMET or INVOKAMET XR.


Excessive Alcohol Intake:Alcohol potentiates the effect of metformin on lactate metabolism and this may increase the risk of metformin-associated lactic acidosis. Warn patients against excessive alcohol intake while receiving INVOKAMET or INVOKAMET XR.


Hepatic Impairment:Patients with hepatic impairment have developed metformin-associated lactic acidosis. This may be due to impaired lactate clearance resulting in higher lactate blood levels. Therefore, avoid use of INVOKAMET or INVOKAMET XR in patients with clinical or laboratory evidence of hepatic disease.

5.2 Diabetic Ketoacidosis in Patients with Type 1 Diabetes Mellitus and Other Ketoacidosis


In patients with type 1 diabetes mellitus, INVOKAMET or INVOKAMET XR significantly increases the risk of diabetic ketoacidosis, a life-threatening event, beyond the background rate. In placebo-controlled trials of patients with type 1 diabetes mellitus, the risk of ketoacidosis was markedly increased in patients who received sodium glucose transporter 2 (SGLT2) inhibitors compared to patients who received placebo; this risk may be greater with higher doses of INVOKAMET or INVOKAMET XR. INVOKAMET or INVOKAMET XR is not indicated for glycemic control in patients with type 1 diabetes mellitus.

Type 2 diabetes mellitus and pancreatic disorders (e.g., history of pancreatitis or pancreatic surgery) are also risk factors for ketoacidosis. There have been postmarketing reports of fatal events of ketoacidosis in patients with type 2 diabetes mellitus using SGLT2 inhibitors, including INVOKAMET or INVOKAMET XR.

Precipitating conditions for diabetic ketoacidosis or other ketoacidosis include under-insulinization due to insulin dose reduction or missed insulin doses, acute febrile illness, reduced caloric intake, ketogenic diet, surgery, volume depletion, and alcohol abuse.

Signs and symptoms are consistent with dehydration and severe metabolic acidosis and include nausea, vomiting, abdominal pain, generalized malaise, and shortness of breath. Blood glucose levels at presentation may be below those typically expected for diabetic ketoacidosis (e.g., less than 250 mg/dL). Ketoacidosis and glucosuria may persist longer than typically expected. Urinary glucose excretion persists for 3 days after discontinuing INVOKAMET or INVOKAMET XR [see Clinical Pharmacology (12.2)] ; however, there have been postmarketing reports of ketoacidosis and/or glucosuria lasting greater than 6 days and some up to 2 weeks after discontinuation of SGLT2 inhibitors.

Consider ketone monitoring in patients at risk for ketoacidosis if indicated by the clinical situation. Assess for ketoacidosis regardless of presenting blood glucose levels in patients who present with signs and symptoms consistent with severe metabolic acidosis. If ketoacidosis is suspected, discontinue INVOKAMET or INVOKAMET XR, promptly evaluate, and treat ketoacidosis, if confirmed. Monitor patients for resolution of ketoacidosis before restarting INVOKAMET or INVOKAMET XR.

Withhold INVOKAMET or INVOKAMET XR, if possible, in temporary clinical situations that could predispose patients to ketoacidosis. Resume INVOKAMET or INVOKAMET XR when the patient is clinically stable and has resumed oral intake [see Dosage and Administration (2.7)] .

Educate all patients on the signs and symptoms of ketoacidosis and instruct patients to discontinue INVOKAMET or INVOKAMET XR and seek medical attention immediately if signs and symptoms occur.

5.3 Lower Limb Amputation


An increased risk of lower limb amputations associated with canagliflozin, a component of INVOKAMET or INVOKAMET XR, versus placebo was observed in CANVAS (5.9 vs 2.8 events per 1000 patient-years) and CANVAS-R (7.5 vs 4.2 events per 1000 patient-years), two randomized, placebo-controlled trials evaluating patients with type 2 diabetes who had either established cardiovascular disease or were at risk for cardiovascular disease. The risk of lower limb amputations was observed at both the 100 mg and 300 mg once daily dosage regimens. The amputation data for CANVAS and CANVAS-R are shown in Tables 4 and 5, respectively [see Adverse Reactions (6.1)] .

Amputations of the toe and midfoot (99 out of 140 patients with amputations receiving canagliflozin in the two trials) were the most frequent; however, amputations involving the leg, below and above the knee, were also observed (41 out of 140 patients with amputations receiving canagliflozin in the two trials). Some patients had multiple amputations, some involving both lower limbs.

Lower limb infections, gangrene, and diabetic foot ulcers were the most common precipitating medical events leading to the need for an amputation. The risk of amputation was highest in patients with a baseline history of prior amputation, peripheral vascular disease, and neuropathy.

Counsel patients about the importance of routine preventative foot care. Monitor patients receiving INVOKAMET or INVOKAMET XR for signs and symptoms of infection (including osteomyelitis), new pain or tenderness, sores or ulcers involving the lower limbs, and discontinue INVOKAMET or INVOKAMET XR if these complications occur.

5.4 Volume Depletion


Canagliflozin can cause intravascular volume contraction which may sometimes manifest as symptomatic hypotension or acute transient changes in creatinine [see Adverse Reactions (6.1)] . There have been post-marketing reports of acute kidney injury which are likely related to volume depletion, some requiring hospitalizations and dialysis, in patients with type 2 diabetes mellitus receiving SGLT2 inhibitors, including canagliflozin. Patients with impaired renal function (eGFR less than 60 mL/min/1.73 m 2), elderly patients, or patients on loop diuretics may be at increased risk for volume depletion or hypotension. Before initiating INVOKAMET or INVOKAMET XR in patients with one or more of these characteristics, assess and correct volume status. Monitor for signs and symptoms of volume depletion after initiating therapy.

5.5 Urosepsis and Pyelonephritis


There have been postmarketing reports of serious urinary tract infections including urosepsis and pyelonephritis requiring hospitalization in patients receiving canagliflozin. Treatment with INVOKAMET or INVOKAMET XR increases the risk for urinary tract infections. Evaluate patients for signs and symptoms of urinary tract infections and treat promptly, if indicated [see Adverse Reactions (6)] .

5.6 Hypoglycemia with Concomitant Use of Sulfonylurea or Insulin


Insulin and insulin secretagogues are known to cause hypoglycemia. INVOKAMET or INVOKAMET XR may increase the risk of hypoglycemia when combined with insulin or an insulin secretagogue [see Adverse Reactions (6.1)] . Therefore, a lower dose of insulin or insulin secretagogue may be required to minimize the risk of hypoglycemia when used in combination with INVOKAMET or INVOKAMET XR.

5.7 Necrotizing Fasciitis of the Perineum (Fournier's Gangrene)


Reports of necrotizing fasciitis of the perineum (Fournier's gangrene), a rare but serious and life-threatening necrotizing infection requiring urgent surgical intervention, have been identified in postmarketing surveillance in patients with diabetes mellitus receiving SGLT2 inhibitors, including canagliflozin. Cases have been reported in both females and males. Serious outcomes have included hospitalization, multiple surgeries, and death.

Patients treated with INVOKAMET or INVOKAMET XR presenting with pain or tenderness, erythema, or swelling in the genital or perineal area, along with fever or malaise, should be assessed for necrotizing fasciitis. If suspected, start treatment immediately with broad-spectrum antibiotics and, if necessary, surgical debridement. Discontinue INVOKAMET or INVOKAMET XR, closely monitor blood glucose levels, and provide appropriate alternative therapy for glycemic control.

5.8 Genital Mycotic Infections


Canagliflozin increases the risk of genital mycotic infections. Patients with a history of genital mycotic infections and uncircumcised males were more likely to develop genital mycotic infections [see Adverse Reactions (6.1)] . Monitor and treat appropriately.

5.9 Hypersensitivity Reactions


Hypersensitivity reactions, including angioedema and anaphylaxis, have been reported with canagliflozin. These reactions generally occurred within hours to days after initiating canagliflozin. If hypersensitivity reactions occur, discontinue use of INVOKAMET or INVOKAMET XR; treat and monitor until signs and symptoms resolve [see Contraindications (4)and Adverse Reactions (6.1, 6.2)] .

5.10 Bone Fracture


An increased risk of bone fracture, occurring as early as 12 weeks after treatment initiation, was observed in patients using canagliflozin in the CANVAS trial [see Clinical Studies (14.2)] . Consider factors that contribute to fracture risk prior to initiating INVOKAMET or INVOKAMET XR [see Adverse Reactions (6.1)] .

5.11 Vitamin B Levels


In metformin HCl clinical trials of 29-week duration, a decrease to subnormal levels of previously normal serum vitamin B 12levels was observed in approximately 7% of patients. Such decrease, possibly due to interference with B 12absorption from the B 12-intrinsic factor complex, may be associated with anemia but appears to be rapidly reversible with discontinuation of metformin HCl or vitamin B 12supplementation. Certain individuals (those with inadequate vitamin B 12or calcium intake or absorption) appear to be predisposed to developing subnormal vitamin B 12levels.

6.1 Clinical Studies Experience


Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to the rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice.


Pool of Placebo-Controlled Trials for Glycemic Control


Canagliflozin

The data in Table 3 is derived from four 26-week placebo-controlled trials where canagliflozin was used as monotherapy in one trial and as add-on therapy in three trials. These data reflect exposure of 1,667 patients to canagliflozin and a mean duration of exposure to canagliflozin of 24 weeks with 1,275 patients exposed to a combination of canagliflozin and metformin HCl. Patients received canagliflozin 100 mg (N=833), canagliflozin 300 mg (N=834) or placebo (N=646) once daily. The mean daily dose of metformin HCl was 2,138 mg (SD 337.3) for the 1,275 patients in the three placebo-controlled metformin HCl add-on trials. The mean age of the population was 56 years and 2% were older than 75 years of age. Fifty percent (50%) of the population was male and 72% were Caucasian, 12% were Asian, and 5% were Black or African American. At baseline the population had diabetes for an average of 7.3 years, had a mean HbA 1Cof 8.0% and 20% had established microvascular complications of diabetes. Baseline renal function was normal or mildly impaired (mean eGFR 88 mL/min/1.73 m 2).

Table 3 shows common adverse reactions associated with the use of canagliflozin. These adverse reactions were not present at baseline, occurred more commonly on canagliflozin than on placebo, and occurred in at least 2% of patients treated with either canagliflozin 100 mg or canagliflozin 300 mg.
Table 3: Adverse Reactions from Pool of Four 26−Week Placebo-Controlled Studies Reported in ≥ 2% of Canagliflozin-Treated Patients The four placebo-controlled trials included one monotherapy trial and three add-on combination trials with metformin HCl, metformin HCl and sulfonylurea, or metformin HCl and pioglitazone.

Abdominal pain was also more commonly reported in patients taking canagliflozin 100 mg (1.8%), 300 mg (1.7%) than in patients taking placebo (0.8%).


Canagliflozin and Metformin HCl

The incidence and type of adverse reactions in the three 26-week placebo-controlled metformin HCl tablets add-on trials, representing a majority of data from the four 26-week placebo-controlled trials, was similar to the adverse reactions described in Table 3. There were no additional adverse reactions identified in the pooling of these three placebo-controlled trials that included metformin HCl tablets relative to the four placebo-controlled trials.

In a trial with canagliflozin as initial combination therapy with metformin HCl [see Clinical Studies (14.1)] , an increased incidence of diarrhea was observed in the canagliflozin and metformin HCl combination groups (4.2%) compared to canagliflozin or metformin HCl monotherapy groups (1.7%).


Placebo-Controlled Trial in Diabetic Nephropathy

The occurrence of adverse reactions for canagliflozin was evaluated in patients participating in CREDENCE, a study in patients with type 2 diabetes mellitus and diabetic nephropathy with albuminuria ˃ 300 mg/day [see Clinical Studies (14.3)] . These data reflect exposure of 2,201 patients to canagliflozin and a mean duration of exposure to canagliflozin of 137 weeks.

The rate of lower limb amputations associated with the use of canagliflozin 100 mg relative to placebo was 12.3 vs 11.2 events per 1000 patient-years, respectively, with 2.6 years mean duration of follow-up.

The incidence of hypotension was 2.8% and 1.5% on canagliflozin 100 mg and placebo, respectively.


Pool of Placebo- and Active-Controlled Trials for Glycemic Control and Cardiovascular Outcomes

The occurrence of adverse reactions for canagliflozin was evaluated in patients participating in placebo- and active-controlled trials and in an integrated analysis of two cardiovascular trials, CANVAS and CANVAS-R.

The types and frequency of common adverse reactions observed in the pool of eight clinical trials (which reflect an exposure of 6,177 patients to canagliflozin) were consistent with those uled in Table 3. Percentages were weighted by studies. Study weights were proportional to the harmonic mean of the three treatment sample sizes. In this pool, canagliflozin was also associated with the adverse reactions of fatigue (1.8%, 2.2%, and 2.0% with comparator, canagliflozin 100 mg, and canagliflozin 300 mg, respectively) and loss of strength or energy (i.e., asthenia) (0.6%, 0.7%, and 1.1% with comparator, canagliflozin 100 mg, and canagliflozin 300 mg, respectively).

In the pool of eight clinical trials, the incidence rate of pancreatitis (acute or chronic) was 0.1%, 0.2%, and 0.1% receiving comparator, canagliflozin 100 mg, and canagliflozin 300 mg, respectively.

In the pool of eight clinical trials, hypersensitivity-related adverse reactions (including erythema, rash, pruritus, urticaria, and angioedema) was 3.0%, 3.8%, and 4.2% of patients receiving comparator, canagliflozin 100 mg, and canagliflozin 300 mg, respectively. Five patients experienced serious adverse reactions of hypersensitivity with canagliflozin, which included 4 patients with urticaria and 1 patient with a diffuse rash and urticaria occurring within hours of exposure to canagliflozin. Among these patients, 2 patients discontinued canagliflozin. One patient with urticaria had recurrence when canagliflozin was re-initiated.

Photosensitivity-related adverse reactions (including photosensitivity reaction, polymorphic light eruption, and sunburn) occurred in 0.1%, 0.2%, and 0.2% of patients receiving comparator, canagliflozin 100 mg, and canagliflozin 300 mg, respectively.

Other adverse reactions occurring more frequently on canagliflozin than on comparator were:


Lower Limb Amputation

An increased risk of lower limb amputations associated with canagliflozin was observed in CANVAS (5.9 vs 2.8 events per 1000 patient-years) and CANVAS-R (7.5 vs 4.2 events per 1000 patient-years), two randomized, placebo-controlled trials evaluating patients with type 2 diabetes who had either established cardiovascular disease or were at risk for cardiovascular disease. Patients in CANVAS and CANVAS-R were followed for an average of 5.7 and 2.1 years, respectively [see Clinical Studies (14.2)] . The amputation data for CANVAS and CANVAS-R are shown in Tables 4 and 5, respectively .

Renal Cell Carcinoma

In the CANVAS trial (mean duration of follow-up of 5.7 years) [see Clinical Studies (14.2)] , the incidence of renal cell carcinoma was 0.15% (2/1331) and 0.29% (8/2716) for placebo and canagliflozin, respectively, excluding patients with less than 6 months of follow-up, less than 90 days of treatment, or a history of renal cell carcinoma. A causal relationship to canagliflozin could not be established due to the limited number of cases.


Volume Depletion-Related Adverse Reactions

Canagliflozin results in an osmotic diuresis, which may lead to reductions in intravascular volume. In clinical trials for glycemic control, treatment with canagliflozin was associated with a dose-dependent increase in the incidence of volume depletion-related adverse reactions (e.g., hypotension, postural dizziness, orthostatic hypotension, syncope, and dehydration). An increased incidence was observed in patients on the 300 mg dose. The three factors associated with the largest increase in volume depletion-related adverse reactions in these trials were the use of loop diuretics, moderate renal impairment (eGFR 30 to less than 60 mL/min/1.73 m 2), and age 75 years and older (Table 6) [see Use in Specific Populations (8.5and 8.6)] .

eGFR less than 60 mL/min/1.73 m 2 2.5% 4.7% 8.1%
Use of loop diuretic 4.7% 3.2% 8.8%


Falls

In a pool of nine clinical trials with mean duration of exposure to canagliflozin of 85 weeks, the proportion of patients who experienced falls was 1.3%, 1.5%, and 2.1% with comparator, canagliflozin 100 mg, and canagliflozin 300 mg, respectively. The higher risk of falls for patients treated with canagliflozin was observed within the first few weeks of treatment.


Genital Mycotic Infections

In the pool of four placebo-controlled clinical trials for glycemic control, female genital mycotic infections (e.g., vulvovaginal mycotic infection, vulvovaginal candidiasis, and vulvovaginitis) occurred in 2.8%, 10.6%, and 11.6% of females treated with placebo, canagliflozin 100 mg, and canagliflozin 300 mg, respectively. Patients with a history of genital mycotic infections were more likely to develop genital mycotic infections on canagliflozin. Female patients who developed genital mycotic infections on canagliflozin were more likely to experience recurrence and require treatment with oral or topical antifungal agents and anti-microbial agents. In females, discontinuation due to genital mycotic infections occurred in 0% and 0.7% of patients treated with placebo and canagliflozin, respectively.

In the pool of four placebo-controlled clinical trials, male genital mycotic infections (e.g., candidal balanitis, balanoposthitis) occurred in 0.7%, 4.2%, and 3.8% of males treated with placebo, canagliflozin 100 mg, and canagliflozin 300 mg, respectively. Male genital mycotic infections occurred more commonly in uncircumcised males and in males with a prior history of balanitis or balanoposthitis. Male patients who developed genital mycotic infections on canagliflozin were more likely to experience recurrent infections (22% on canagliflozin versus none on placebo), and require treatment with oral or topical antifungal agents and anti-microbial agents than patients on comparators. In males, discontinuations due to genital mycotic infections occurred in 0% and 0.5% of patients treated with placebo and canagliflozin, respectively.

In the pooled analysis of 8 randomized trials evaluating glycemic control, phimosis was reported in 0.3% of uncircumcised male patients treated with canagliflozin and 0.2% required circumcision to treat the phimosis.


Hypoglycemia

In canagliflozin glycemic control trials, hypoglycemia was defined as any event regardless of symptoms, where biochemical hypoglycemia was documented (any glucose value below or equal to 70 mg/dL). Severe hypoglycemia was defined as an event consistent with hypoglycemia where the patient required the assistance of another person to recover, lost consciousness, or experienced a seizure (regardless of whether biochemical documentation of a low glucose value was obtained). In individual clinical trials of glycemic control [see Clinical Studies (14.1)] , episodes of hypoglycemia occurred at a higher rate when canagliflozin was co-administered with insulin or sulfonylureas (Table 7).

Bone Fracture

In the CANVAS trial [see Clinical Studies (14.2)] , the incidence rates of all adjudicated bone fracture were 1.09, 1.59, and 1.79 events per 100 patient-years of follow-up to placebo, canagliflozin 100 mg, and canagliflozin 300 mg, respectively. The fracture imbalance was observed within the first 26 weeks of therapy and remained through the end of the trial. Fractures were more likely to be low trauma (e.g., fall from no more than standing height), and affect the distal portion of upper and lower extremities.


Metformin HCl

The most common adverse reactions (5% or greater incidence) due to initiation of metformin HCl are diarrhea, nausea, vomiting, flatulence, asthenia, indigestion, abdominal discomfort, and headache.

In metformin clinical trials of 29-week duration, a decrease to subnormal levels of previously normal serum vitamin B 12levels was observed in approximately 7% of patients.


Laboratory and Imaging Tests


Increases in Serum Creatinine and Decreases in eGFR

Initiation of canagliflozin causes an increase in serum creatinine and decrease in estimated GFR. In patients with moderate renal impairment, the increase in serum creatinine generally does not exceed 0.2 mg/dL, occurs within the first 6 weeks of starting therapy, and then stabilizes. Increases that do not fit this pattern should prompt further evaluation to exclude the possibility of acute kidney injury [see Clinical Pharmacology (12.1)] . The acute effect on eGFR reverses after treatment discontinuation suggesting acute hemodynamic changes may play a role in the renal function changes observed with canagliflozin.


Increases in Serum Potassium

In a pooled population of patients (N=723) in glycemic control trials with moderate renal impairment (eGFR 45 to less than 60 mL/min/1.73 m 2), increases in serum potassium to greater than 5.4 mEq/L and 15% above occurred in 5.3%, 5.0%, and 8.8% of patients treated with placebo, canagliflozin 100 mg, and canagliflozin 300 mg, respectively. Severe elevations (greater than or equal to 6.5 mEq/L) occurred in 0.4% of patients treated with placebo, no patients treated with canagliflozin 100 mg, and 1.3% of patients treated with canagliflozin 300 mg.

In these patients, increases in potassium were more commonly seen in those with elevated potassium at baseline. Among patients with moderate renal impairment, approximately 84% were taking medications that interfere with potassium excretion, such as potassium-sparing diuretics, angiotensin-converting-enzyme inhibitors, and angiotensin-receptor blockers [see Use in Specific Populations (8.6)].

In CREDENCE, no difference in serum potassium, no increase in adverse events of hyperkalemia, and no increase in absolute (> 6.5 mEq/L) or relative (> upper limit of normal and > 15% increase from baseline) increases in serum potassium were observed with canagliflozin 100 mg relative to placebo.


Increases in Low-Density Lipoprotein Cholesterol (LDL-C) and non-High-Density Lipoprotein Cholesterol (non-HDL-C)

In the pool of four glycemic control placebo-controlled trials, dose-related increases in LDL-C with canagliflozin were observed. Mean changes (percent changes) from baseline in LDL-C relative to placebo were 4.4 mg/dL (4.5%) and 8.2 mg/dL (8.0%) with canagliflozin 100 mg and canagliflozin 300 mg, respectively. The mean baseline LDL-C levels were 104 to 110 mg/dL across treatment groups.

Dose-related increases in non-HDL-C with canagliflozin were observed. Mean changes (percent changes) from baseline in non-HDL-C relative to placebo were 2.1 mg/dL (1.5%) and 5.1 mg/dL (3.6%) with canagliflozin 100 mg and 300 mg, respectively. The mean baseline non-HDL-C levels were 140 to 147 mg/dL across treatment groups.


Increases in Hemoglobin

In the pool of four placebo-controlled trials of glycemic control, mean changes (percent changes) from baseline in hemoglobin were -0.18 g/dL (-1.1%) with placebo, 0.47 g/dL (3.5%) with canagliflozin 100 mg, and 0.51 g/dL (3.8%) with canagliflozin 300 mg. The mean baseline hemoglobin value was approximately 14.1 g/dL across treatment groups. At the end of treatment, 0.8%, 4.0%, and 2.7% of patients treated with placebo, canagliflozin 100 mg, and canagliflozin 300 mg, respectively, had hemoglobin above the upper limit of normal.


Decreases in Bone Mineral Density

Bone mineral density (BMD) was measured by dual-energy X-ray absorptiometry in a clinical trial of 714 older adults (mean age 64 years). At 2 years, patients randomized to canagliflozin 100 mg and canagliflozin 300 mg had placebo-corrected declines in BMD at the total hip of 0.9% and 1.2%, respectively, and at the lumbar spine of 0.3% and 0.7%, respectively. Additionally, placebo-adjusted BMD declines were 0.1% at the femoral neck for both canagliflozin doses and 0.4% at the distal forearm for patients randomized to canagliflozin 300 mg. The placebo-adjusted change at the distal forearm for patients randomized to canagliflozin 100 mg was 0%.

6.2 Postmarketing Experience


Additional adverse reactions have been identified during post-approval use of canagliflozin and/or metformin. Because these reactions are reported voluntarily from a population of uncertain size, it is generally not possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

7 Drug Interactions

Table 8: Clinically Significant Drug Interactions with INVOKAMET or INVOKAMET XR
Carbonic Anhydrase Inhibitors
Clinical Impact: Carbonic anhydrase inhibitors frequently cause a decrease in serum bicarbonate and induce non-anion gap, hyperchloremic metabolic acidosis. Concomitant use of these drugs with INVOKAMET or INVOKAMET XR may increase the risk for lactic acidosis.
Intervention: Consider more frequent monitoring of these patients.
Examples: Topiramate or other carbonic anhydrase inhibitors (e.g., zonisamide, acetazolamide or dichlorphenamide)
Drugs That Reduce Metformin Clearance
Clinical Impact: Concomitant use of drugs that interfere with common renal tubular transport systems involved in the renal elimination of metformin (e.g., organic cationic transporter-2 [OCT2] / multidrug and toxin extrusion [MATE] inhibitors could increase systemic exposure to metformin and may increase the risk for lactic acidosis [see Clinical Pharmacology (12.3)].
Intervention: Consider the benefits and risks of concomitant use.
Examples: Ranolazine, vandetanib, dolutegravir, and cimetidine
Alcohol
Clinical Impact: Alcohol is known to potentiate the effect of metformin HCl on lactate metabolism.
Intervention: Warn patients against excessive alcohol intake while receiving INVOKAMET or INVOKAMET XR.
UGT Enzyme Inducers
Clinical Impact: UGT enzyme inducers decrease canagliflozin exposure which may reduce the effectiveness of INVOKAMET or NVOKAMET XR.
Intervention: For patients with eGFR 60 mL/min/1.73 m 2or greater, if an inducer of UGTs is co-administered with INVOKAMET or INVOKAMET XR, increase the total daily dose of canagliflozin to 200 mg in patients currently tolerating INVOKAMET or INVOKAMET XR with a total daily dose of canagliflozin 100 mg. The total daily dose of canagliflozin may be increased to 300 mg in patients currently tolerating canagliflozin 200 mg and who require additional glycemic control. For patients with eGFR less than 60 mL/min/1.73 m 2, if an inducer of UGTs is co-administered with INVOKAMET or INVOKAMET XR, increase the total daily dose of canagliflozin to 200 mg in patients currently tolerating canagliflozin 100 mg [see Dosage and Administration (2.5)and Clinical Pharmacology (12.3)] .
Examples: Rifampin, phenytoin, phenobarbital, ritonavir
Insulin Secretagogues or Insulin
Clinical Impact: The risk of hypoglycemia is increased when INVOKAMET or INVOKAMET XR is used concomitantly with insulin secretagogues (e.g., sulfonylurea) or insulin.
Intervention: Concomitant use may require a lower dosage of the insulin secretagogue or insulin to reduce the risk of hypoglycemia.
Drugs Affecting Glycemic Control
Clinical Impact: Certain drugs tend to produce hyperglycemia and may lead to loss of glycemic control.
Intervention: When such drugs are administered to a patient receiving INVOKAMET or INVOKAMET XR, monitor for loss of blood glucose control. When such drugs are withdrawn from a patient receiving INVOKAMET or INVOKAMET XR, monitor for hypoglycemia.
Examples: Thiazides and other diuretics, corticosteroids, phenothiazines, thyroid products, estrogens, oral contraceptives, phenytoin, nicotinic acid, sympathomimetics, calcium channel blockers, and isoniazid.
Digoxin
Clinical Impact: Canagliflozin increases digoxin exposure [see Clinical Pharmacology (12.3)] .
Intervention: Monitor patients taking INVOKAMET or INVOKAMET XR with concomitant digoxin for a need to adjust dose of digoxin.
Lithium
Clinical Impact: Concomitant use of an SGLT2 inhibitor with lithium may decrease serum lithium concentrations.
Intervention: Monitor serum lithium concentration more frequently during INVOKAMET or INVOKAMET XR initiation and dosage changes.
Drug/Laboratory Test Interference
Positive Urine Glucose Test
Clinical Impact: SGLT2 inhibitors increase urinary glucose excretion which will lead to positive urine glucose tests.
Intervention: Monitoring glycemic control with urine glucose tests is not recommended in patients taking SGLT2 inhibitors. Use alternative methods to monitor glycemic control.
Interference with 1,5-anhydroglucitol (1,5-AG) Assay
Clinical Impact: Measurements of 1,5-AG are unreliable in assessing glycemic control in patients taking SGLT2 inhibitors.
Intervention: Monitoring glycemic control with 1,5-AG assay is not recommended in patients taking SGLT2 inhibitors. Use alternative methods to monitor glycemic control.

  • Carbonic Anhydrase Inhibitors:May increase risk of lactic acidosis. Consider more frequent monitoring ( 7)
  • Drugs that Reduce Metformin Clearance:May increase risk of lactic acidosis. Consider benefits and risks of concomitant use ( 7)

8 Use In Specific Populations


  • Pregnancy: Advise females of the potential risk to a fetus especially during the second and third trimesters ( 8.1)
  • Lactation: Not recommended when breastfeeding ( 8.2)
  • Females and Males of Reproductive Potential: Advise premenopausal females of the potential for an unintended pregnancy ( 8.3)
  • Geriatrics: Higher incidence of adverse reactions related to reduced intravascular volume. Assess renal function more frequently ( 6.1, 8.5)
  • Renal impairment: Higher incidence of adverse reactions related to hypotension and renal function ( 8.6)
  • Hepatic impairment: Avoid use in patients with hepatic impairment ( 8.7)

8.1 Pregnancy


Risk Summary

Based on animal data showing adverse renal effects from canagliflozin, INVOKAMET or INVOKAMET XR is not recommended during the second and third trimesters of pregnancy.

Limited data with INVOKAMET, INVOKAMET XR or canagliflozin in pregnant women are not sufficient to determine a drug-associated risk for major birth defects or miscarriage. Published studies with metformin HCl use during pregnancy have not reported a clear association with metformin HCl and major birth defect or miscarriage risk [see Data]. There are risks to the mother and fetus associated with poorly controlled diabetes in pregnancy [see Clinical Considerations].

In animal studies, adverse renal pelvic and tubule dilatations that were not reversible were observed in rats when canagliflozin was administered at an exposure 0.5-times the 300 mg clinical dose, based on AUC during a period of renal development corresponding to the late second and third trimesters of human pregnancy. No adverse developmental effects were observed when metformin HCl was administered to pregnant Sprague Dawley rats and rabbits during the period of organogenesis at doses up to 2- and 6-times, respectively, a 2000 mg clinical dose, based on body surface area [see Data] .

The estimated background risk of major birth defects is 6–10% in women with pre-gestational diabetes with an HbA 1C>7 and has been reported to be as high as 20–25% in women with a HbA 1C>10. The estimated background risk of miscarriage for the indicated population is unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2–4% and 15–20%, respectively.


Clinical Considerations


Disease-associated Maternal and/or Embryo/Fetal Risk

Poorly controlled diabetes in pregnancy increases the maternal risk for diabetic ketoacidosis, pre-eclampsia, spontaneous abortions, preterm delivery, and delivery complications. Poorly controlled diabetes increases the fetal risk for major birth defects, stillbirth, and macrosomia related morbidity.


Data


Human Data

Published data from post-marketing studies have not reported a clear association with metformin HCl and major birth defects, miscarriage, or adverse maternal or fetal outcomes when metformin HCl was used during pregnancy. However, these studies cannot definitely establish the absence of any metformin-associated risk because of methodological limitations, including small sample size and inconsistent comparator groups.


Animal Data

8.2 Lactation



Risk Summary

There is no information regarding the presence of INVOKAMET, INVOKAMET XR or canagliflozin in human milk, the effects on the breastfed infant, or the effects on milk production. Limited published studies report that metformin is present in human milk [see Data] . However, there is insufficient information on the effects of metformin HCl on the breastfed infant and no available information on the effects of metformin HCl on milk production. Canagliflozin is present in the milk of lactating rats [see Data] . Since human kidney maturation occurs in uteroand during the first 2 years of life when lactational exposure may occur, there may be risk to the developing human kidney.

Because of the potential for serious adverse reactions in a breastfed infant, advise women that use of INVOKAMET or INVOKAMET XR is not recommended while breastfeeding.


Data

Published clinical lactation studies report that metformin is present in human milk which resulted in infant doses approximately 0.11% to 1% of the maternal weight-adjusted dosage and a milk/plasma ratio ranging between 0.13 and 1. However, the studies were not designed to definitely establish the risk of use of metformin HCl during lactation because of small sample size and limited adverse event data collected in infants.

Radiolabeled canagliflozin administered to lactating rats on day 13 post-partum was present at a milk/plasma ratio of 1.40, indicating that canagliflozin and its metabolites are transferred into milk at a concentration comparable to that in plasma. Juvenile rats directly exposed to canagliflozin showed a risk to the developing kidney (renal pelvic and tubular dilatations) during maturation.

8.3 Females and Males of Reproductive Potential


Discuss the potential for unintended pregnancy with premenopausal women as therapy with metformin HCl may result in ovulation in some anovulatory women.

8.4 Pediatric Use


Safety and effectiveness of INVOKAMET or INVOKAMET XR in pediatric patients under 18 years of age have not been established.

8.5 Geriatric Use



INVOKAMET and INVOKAMET XR

Because renal function abnormalities can occur after initiating canagliflozin, metformin is substantially excreted by the kidney, and aging can be associated with reduced renal function, monitor renal function more frequently after initiating INVOKAMET or INVOKAMET XR in the elderly and then adjust dose based on renal function [see Dosage and Administration (2.4)and Warnings and Precautions (5.1, 5.4)] .


Canagliflozin

In 13 clinical trials of canagliflozin, 2,294 patients 65 years and older, and 351 patients 75 years and older were exposed to canagliflozin. Of these patients, 1,534 patients 65 years and older and 196 patients 75 years and older were exposed to the combination of canagliflozin and metformin HCl [see Clinical Studies (14)] . Patients 65 years and older had a higher incidence of adverse reactions related to reduced intravascular volume with canagliflozin (such as hypotension, postural dizziness, orthostatic hypotension, syncope, and dehydration), particularly with the 300 mg daily dose, compared to younger patients; a more prominent increase in the incidence was seen in patients who were 75 years and older [see Dosage and Administration (2.1)and Adverse Reactions (6.1)]. Smaller reductions in HbA 1Cwith canagliflozin relative to placebo were seen in older (65 years and older; -0.61% with canagliflozin 100 mg and -0.74% with canagliflozin 300 mg relative to placebo) compared to younger patients (-0.72% with canagliflozin 100 mg and -0.87% with canagliflozin 300 mg relative to placebo).


Metformin HCl

Controlled clinical trials of metformin HCl did not include sufficient numbers of elderly patients to determine whether they respond differently from younger patients, although other reported clinical experience has not identified differences in responses between the elderly and younger patients. The initial and maintenance dosing of metformin HCl should be conservative in patients with advanced age due to the potential for decreased renal function in this population. Any dose adjustment should be based on a careful assessment of renal function [see Contraindications (4), Warnings and Precautions (5.4), and Clinical Pharmacology (12.3)] .

8.6 Renal Impairment



Canagliflozin

The efficacy and safety of canagliflozin for glycemic control were evaluated in a trial that included patients with moderate renal impairment (eGFR 30 to less than 50 mL/min/1.73 m 2). These patients had less overall glycemic efficacy, and patients treated with canagliflozin 300 mg per day had increases in serum potassium, which were transient and similar by the end of study. Patients with renal impairment using canagliflozin for glycemic control may also be more likely to experience hypotension and may be at higher risk for acute kidney injury [see Warnings and Precautions (5.4)] .

Efficacy and safety studies with canagliflozin did not enroll patients with ESKD on dialysis or patients with an eGFR less than 30 mL/min/1.73 m 2 [see Clinical Pharmacology (12.3)] .


Metformin HCl

Metformin is substantially excreted by the kidney, and the risk of metformin accumulation and lactic acidosis increases with the degree of renal impairment. INVOKAMET or INVOKAMET XR is contraindicated in severe renal impairment (eGFR less than 30 mL/min/1.73 m 2) or in patients on dialysis [see Dosage and Administration (2.4), Contraindications (4), Warnings and Precautions (5.1), and Clinical Pharmacology (12.3)].

8.7 Hepatic Impairment


Use of metformin HCl in patients with hepatic impairment has been associated with some cases of lactic acidosis. INVOKAMET or INVOKAMET XR is not recommended in patients with hepatic impairment [see Warnings and Precautions (5.1)].

10 Overdosage


Overdose of metformin HCl has occurred, including ingestion of amounts greater than 50 grams. Hypoglycemia was reported in approximately 10% of cases, but no causal association with metformin HCl use has been established. Lactic acidosis has been reported in approximately 32% of metformin HCl overdose cases [see Warnings and Precautions (5.1)] .

In the event of an overdose with INVOKAMET or INVOKAMET XR, contact the Poison Control Center. Employ the usual supportive measures (e.g., remove unabsorbed material from the gastrointestinal tract, employ clinical monitoring, and institute supportive treatment) as dictated by the patient's clinical status. Canagliflozin was negligibly removed during a 4-hour hemodialysis session. Canagliflozin is not expected to be dialyzable by peritoneal dialysis. Metformin is dialyzable with a clearance of up to 170 mL/min under good hemodynamic conditions. Therefore, hemodialysis may be useful partly for removal of accumulated metformin from patients in whom INVOKAMET or INVOKAMET XR overdosage is suspected.

11 Description


INVOKAMET ® (canagliflozin and metformin HCl) and INVOKAMET ® XR (canagliflozin and metformin HCl extended-release tablets) contain canagliflozin and metformin HCl.


Canagliflozin

Canagliflozin is an inhibitor of SGLT2, the transporter responsible for reabsorbing the majority of glucose filtered by the kidney. Canagliflozin is chemically known as (1 S)-1,5-anhydro-1-[3-[[5-(4-fluorophenyl)-2-thienyl]methyl]-4-methylphenyl]-D-glucitol hemihydrate and its molecular formula and weight are C 24H 25FO 5S∙1/2 H 2O and 453.53, respectively. The structural formula for canagliflozin is:

Canagliflozin is practically insoluble in aqueous media from pH 1.1 to 12.9.


Metformin HCl

Metformin HCl is a biguanide chemically known as 1,1-Dimethylbiguanide HCl and its molecular formula and weight are C 4H 11N 5∙ HCl and 165.62, respectively. The structural formula for metformin HCl is:


INVOKAMET and INVOKAMET XR

INVOKAMET or INVOKAMET XR are supplied as film-coated tablets for oral administration. Each 50 mg/500 mg tablet and 50 mg/1,000 mg tablet contains 51 mg of canagliflozin equivalent to 50 mg canagliflozin (anhydrous) and 500 mg or 1,000 mg metformin HCl (equivalent to metformin 389.93 mg and 779.86 mg, respectively).

Each 150 mg/500 mg tablet and 150 mg/1,000 mg tablet contains 153 mg of canagliflozin equivalent to 150 mg canagliflozin (anhydrous) and 500 mg or 1,000 mg metformin HCl (equivalent to metformin 389.93 mg and 779.86 mg, respectively).

INVOKAMET contains the following inactive ingredients: croscarmellose sodium, hypromellose, magnesium stearate, and microcrystalline cellulose. The magnesium stearate is vegetable-sourced. The tablets are finished with a commercially available film-coating consisting of the following inactive ingredients: macrogol/PEG3350, polyvinyl alcohol (partially hydrolyzed), talc, titanium dioxide, iron oxide yellow (50 mg/1,000 mg and 150 mg/500 mg tablets only), iron oxide red (50 mg/1,000 mg, 150 mg/500 mg and 150 mg/1,000 mg tablets only), and iron oxide black (150 mg/1,000 mg tablets only).

INVOKAMET XR contains the following inactive ingredients: croscarmellose sodium, hydroxypropyl cellulose, hypromellose, lactose anhydrous, magnesium stearate (vegetable-sourced), microcrystalline cellulose, polyethylene oxide, and silicified microcrystalline cellulose (50 mg/500 mg and 50 mg/1,000 mg tablets only). The tablets are finished with a commercially available film-coating consisting of the following inactive ingredients: macrogol/PEG3350, polyvinyl alcohol (partially hydrolyzed), talc, titanium dioxide, iron oxide red, iron oxide yellow, and iron oxide black (50 mg/1,000 mg and 150 mg/1,000 mg tablets only).

INVOKAMET XR tablets provide canagliflozin for immediate-release and metformin HCl for extended-release. Each bilayer tablet is compressed from two separate granulates, one for each active ingredient of the tablet, and finished with a film-coating. The metformin HCl extended-release layer is based on a polymer matrix which controls the drug release by passive diffusion through the swollen matrix in combination with tablet erosion.

12 Clinical Pharmacology


12.1 Mechanism of Action


Canagliflozin

SGLT2 expressed in the proximal renal tubules, is responsible for the majority of the reabsorption of filtered glucose from the tubular lumen. Canagliflozin is an inhibitor of SGLT2. By inhibiting SGLT2, canagliflozin reduces reabsorption of filtered glucose and lowers the renal threshold for glucose (RT G), and thereby increases urinary glucose excretion (UGE).

Canagliflozin increases the delivery of sodium to the distal tubule by blocking SGLT2-dependent glucose and sodium reabsorption. This is believed to increase tubuloglomerular feedback and reduce intraglomerular pressure.


Metformin HCl

Metformin HCl is an antihyperglycemic agent which improves glucose tolerance in patients with type 2 diabetes, lowering both basal and postprandial plasma glucose. Metformin HCl decreases hepatic glucose production, decreases intestinal absorption of glucose, and improves insulin sensitivity by increasing peripheral glucose uptake and utilization. With metformin therapy, insulin secretion remains unchanged while fasting insulin levels and day-long plasma insulin response may decrease.

12.2 Pharmacodynamics



Canagliflozin

Following single and multiple oral doses of canagliflozin in patients with type 2 diabetes, dose-dependent decreases in RT Gand increases in urinary glucose excretion were observed. From a starting RT Gvalue of approximately 240 mg/dL, canagliflozin at 100 mg and 300 mg once daily suppressed RT Gthroughout the 24-hour period. Data from single oral doses of canagliflozin in healthy volunteers indicate that, on average, the elevation in urinary glucose excretion approaches baseline by about 3 days for doses up to 300 mg once daily. Maximal suppression of mean RT Gover the 24-hour period was seen with the 300 mg daily dose to approximately 70 to 90 mg/dL in patients with type 2 diabetes in Phase 1 trials. The reductions in RT Gled to increases in mean UGE of approximately 100 g/day in patients with type 2 diabetes treated with either 100 mg or 300 mg of canagliflozin. The 24-h mean RT Gat steady state was similar following once daily and twice daily dosing regimens at the same total daily dose of 100 mg or 300 mg. In patients with type 2 diabetes given 100 to 300 mg once daily over a 16-day dosing period, reductions in RT Gand increases in urinary glucose excretion were observed over the dosing period. In this trial, plasma glucose declined in a dose-dependent fashion within the first day of dosing.


Cardiac Electrophysiology

In a randomized, double-blind, placebo-controlled, active-comparator, 4-way crossover trial, 60 healthy subjects were administered a single oral dose of canagliflozin 300 mg, canagliflozin 1,200 mg (4 times the maximum recommended dose), moxifloxacin, and placebo. No meaningful changes in QTc interval were observed with either the recommended dose of 300 mg or the 1,200 mg dose.

12.3 Pharmacokinetics



INVOKAMET

Administration of INVOKAMET 150 mg/1,000 mg fixed-dose combination with food resulted in no change in overall exposure of canagliflozin. There was no change in metformin AUC; however, the mean peak plasma concentration of metformin was decreased by 16% when administered with food. A delayed time to peak plasma concentration was observed for both components (a delay of 2 hours for canagliflozin and 1 hour for metformin) under fed conditions. These changes are not likely to be clinically meaningful.


INVOKAMET XR

After administration of INVOKAMET XR tablets with a high-fat breakfast, the peak (C max) and total (AUC) exposure of canagliflozin were not altered relative to dosing in the fasted state. However, the AUC of metformin increased by approximately 61% and C maxincreased by approximately 13%.


Canagliflozin

The pharmacokinetics of canagliflozin is essentially similar in healthy subjects and patients with type 2 diabetes. Following single-dose oral administration of 100 mg and 300 mg of canagliflozin, peak plasma concentrations (median T max) of canagliflozin occurs within 1 to 2 hours post-dose. Plasma C maxand AUC of canagliflozin increased in a dose-proportional manner from 50 mg to 300 mg. The apparent terminal half-life (t 1/2) was 10.6 hours and 13.1 hours for the 100 mg and 300 mg doses, respectively. Steady-state was reached after 4 to 5 days of once-daily dosing with canagliflozin 100 mg to 300 mg. Canagliflozin does not exhibit time-dependent pharmacokinetics and accumulated in plasma up to 36% following multiple doses of 100 mg and 300 mg. The mean systemic exposure (AUC) at steady state was similar following once daily and twice daily dosing regimens at the same total daily dose of 100 mg or 300 mg.


Absorption


Canagliflozin

The mean absolute oral bioavailability of canagliflozin is approximately 65%.


Metformin

The absolute bioavailability of a metformin HCl 500 mg tablet given under fasting conditions is approximately 50% to 60%. Trials using single oral doses of metformin HCl 500 to 1,500 mg, and 850 to 2,550 mg, indicate that there is a lack of dose proportionality with increasing doses, which is due to decreased absorption rather than an alteration in elimination.

Following a single oral dose of 1,000 mg metformin HCl extended-release tablets (two 500 mg tablets) after a meal, the time to reach maximum plasma metformin concentration (T max) is achieved at approximately 7–8 hours. In both single and multiple-dose trials in healthy subjects, once daily 1,000 mg (two 500 mg tablets) dosing results in up to 35% higher C max, of metformin relative to the immediate-release given as 500 mg twice daily without any change in overall systemic exposure, as measured by AUC.


Distribution


Canagliflozin

The mean steady-state volume of distribution of canagliflozin following a single intravenous infusion in healthy subjects was 83.5 L, suggesting extensive tissue distribution. Canagliflozin is extensively bound to proteins in plasma (99%), mainly to albumin. Protein binding is independent of canagliflozin plasma concentrations. Plasma protein binding is not meaningfully altered in patients with renal or hepatic impairment.


Metformin

The apparent volume of distribution (V/F) of metformin following single oral doses of metformin HCl 850 mg immediate-release tablets averaged 654 ± 358 L. Metformin is negligibly bound to plasma proteins, in contrast to sulfonylureas, which are more than 90% protein bound. Metformin partitions into erythrocytes, most likely as a function of time.


Metabolism


Canagliflozin

O-glucuronidation is the major metabolic elimination pathway for canagliflozin, which is mainly glucuronidated by UGT1A9 and UGT2B4 to two inactive O-glucuronide metabolites. CYP3A4-mediated (oxidative) metabolism of canagliflozin is minimal (approximately 7%) in humans.


Metformin

Intravenous single-dose trials in normal subjects demonstrate that metformin is excreted unchanged in the urine and does not undergo hepatic metabolism (no metabolites have been identified in humans) or biliary excretion.


Excretion


Canagliflozin

Following administration of a single oral [ 14C] canagliflozin dose to healthy subjects, 41.5%, 7.0%, and 3.2% of the administered radioactive dose was recovered in feces as canagliflozin, a hydroxylated metabolite, and an O-glucuronide metabolite, respectively. Enterohepatic circulation of canagliflozin was negligible.

Approximately 33% of the administered radioactive dose was excreted in urine, mainly as O-glucuronide metabolites (30.5%). Less than 1% of the dose was excreted as unchanged canagliflozin in urine. Renal clearance of canagliflozin 100 mg and 300 mg doses ranged from 1.30 to 1.55 mL/min.

Mean systemic clearance of canagliflozin was approximately 192 mL/min in healthy subjects following intravenous administration.


Metformin

Renal clearance is approximately 3.5 times greater than creatinine clearance, which indicates that tubular secretion is the major route of metformin elimination. Following oral administration, approximately 90% of the absorbed drug is eliminated via the renal route within the first 24 hours, with a plasma elimination half-life of approximately 6.2 hours. In blood, the elimination half-life is approximately 17.6 hours, suggesting that the erythrocyte mass may be a compartment of distribution.


Specific Populations

Trials characterizing the pharmacokinetics of canagliflozin and metformin after administration of INVOKAMET or INVOKAMET XR were not conducted in patients with renal and hepatic impairment. Descriptions of the individual components in this patient population are described below.

Drug-Drug Interactions


INVOKAMET and INVOKAMET XR

Pharmacokinetic drug interaction trials with INVOKAMET or INVOKAMET XR have not been performed; however, such trials have been conducted with the individual components canagliflozin and metformin HCl.

Co-administration of multiple doses of canagliflozin (300 mg) and metformin HCl (2,000 mg) given once daily did not meaningfully alter the pharmacokinetics of either canagliflozin or metformin in healthy subjects.

13 Nonclinical Toxicology


13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility


INVOKAMET and INVOKAMET XR

No animal studies have been conducted with the combined products in INVOKAMET or INVOKAMET XR to evaluate carcinogenesis, mutagenesis, or impairment of fertility. The following data are based on findings in studies with canagliflozin and metformin HCl individually.


Canagliflozin


Carcinogenesis

Carcinogenicity was evaluated in 2-year studies conducted in CD1 mice and Sprague-Dawley rats. Canagliflozin did not increase the incidence of tumors in mice dosed at 10, 30, or 100 mg/kg (less than or equal to 14 times exposure from a 300 mg clinical dose).

Testicular Leydig cell tumors, considered secondary to increased luteinizing hormone (LH), increased significantly in male rats at all doses tested (10, 30, and 100 mg/kg). In a 12-week clinical trial, LH did not increase in males treated with canagliflozin.

Renal tubular adenoma and carcinoma increased significantly in male and female rats dosed at 100 mg/kg, or approximately 12-times exposure from a 300 mg clinical dose. Also, adrenal pheochromocytoma increased significantly in males and numerically in females dosed at 100 mg/kg. Carbohydrate malabsorption associated with high doses of canagliflozin was considered a necessary proximal event in the emergence of renal and adrenal tumors in rats. Clinical trials have not demonstrated carbohydrate malabsorption in humans at canagliflozin doses of up to 2-times the recommended clinical dose of 300 mg.


Mutagenesis

Canagliflozin was not mutagenic with or without metabolic activation in the Ames assay. Canagliflozin was mutagenic in the in vitromouse lymphoma assay with but not without metabolic activation. Canagliflozin was not mutagenic or clastogenic in an in vivooral micronucleus assay in rats and an in vivooral Comet assay in rats.


Metformin HCl


Carcinogenesis

Long-term carcinogenicity studies have been performed in rats (dosing duration of 104 weeks) and mice (dosing duration of 91 weeks) at doses up to and including 900 mg/kg/day and 1500 mg/kg/day, respectively. These doses are both approximately 4 times the maximum recommended human daily dose of 2000 mg based on body surface area comparisons. No evidence of carcinogenicity with metformin HCl was found in either male or female mice. Similarly, there was no tumorigenic potential observed with metformin HCl in male rats. There was, however, an increased incidence of benign stromal uterine polyps in female rats treated with 900 mg/kg/day.


Mutagenesis

There was no evidence of a mutagenic potential of metformin HCl in the following in vitrotests: Ames test ( S. typhimurium), gene mutation test (mouse lymphoma cells), or chromosomal aberrations test (human lymphocytes). Results in the in vivomouse micronucleus test were also negative.


Impairment of Fertility

Canagliflozin had no effects on the ability of rats to mate and sire or maintain a litter up to the high dose of 100 mg/kg (approximately 14 times and 18 times the 300 mg clinical dose in males and females, respectively), although there were minor alterations in a number of reproductive parameters (decreased sperm velocity, increased number of abnormal sperm, slightly fewer corpora lutea, fewer implantation sites, and smaller litter sizes) at the highest dosage administered.

Fertility of male or female rats was unaffected by metformin HCl when administered at doses as high as 600 mg/kg/day, which is approximately 3 times the maximum recommended human daily dose based on body surface area comparisons.

14 Clinical Studies


14.1 Glycemic Control Trials in Adults with Type 2 Diabetes Mellitus


Canagliflozin has been studied in combination with metformin HCl alone, metformin HCl and sulfonylurea, metformin HCl and sitagliptin, metformin HCl and a thiazolidinedione (i.e., pioglitazone), and metformin HCl and insulin (with or without other anti-hyperglycemic agents). The efficacy of canagliflozin was compared to a dipeptidyl peptidase-4 (DPP-4) inhibitor (sitagliptin), both as add-on combination therapy with metformin HCl and sulfonylurea, and a sulfonylurea (glimepiride), both as add-on combination therapy with metformin HCl.

There have been no clinical efficacy trials conducted with INVOKAMET or INVOKAMET XR; however, bioequivalence of INVOKAMET or INVOKAMET XR to canagliflozin and metformin HCl co-administered as individual tablets was demonstrated in healthy subjects.


Canagliflozin as Initial Combination Therapy with Metformin HCl

A total of 1,186 patients with type 2 diabetes inadequately controlled with diet and exercise participated in a 26-week double-blind, active-controlled, parallel-group, 5-arm, multicenter trial to evaluate the efficacy and safety of initial therapy with canagliflozin in combination with metformin HCl XR. The median age was 56 years, 48% of patients were men, and the mean baseline eGFR was 87.6 mL/min/1.73 m 2. The median duration of diabetes was 1.6 years, and 72% of patients were treatment naïve. After completing a 2-week single-blind placebo run-in period, patients were randomly assigned for a double-blind treatment period of 26 weeks to 1 of 5 treatment groups (Table 13). The metformin HCl XR dose was initiated at 500 mg/day for the first week of treatment and then increased to 1,000 mg/day. Metformin HCl XR or matching placebo was up-titrated every 2–3 weeks during the next 8 weeks of treatment to a maximum daily dose of 1,500 to 2,000 mg/day, as tolerated; about 90% of patients reached 2,000 mg/day.

At the end of treatment, canagliflozin 100 mg and canagliflozin 300 mg in combination with metformin HCl XR resulted in a statistically significant greater improvement in HbA 1Ccompared to their respective canagliflozin doses (100 mg and 300 mg) alone or metformin HCl XR alone.

Canagliflozin as Add-on Combination Therapy with Metformin HCl

A total of 1,284 patients with type 2 diabetes inadequately controlled on metformin HCl monotherapy (greater than or equal to 2,000 mg/day or at least 1,500 mg/day if higher dose not tolerated) participated in a 26-week, double-blind, placebo- and active-controlled trial to evaluate the efficacy and safety of canagliflozin in combination with metformin HCl. The mean age was 55 years, 47% of patients were men, and the mean baseline eGFR was 89 mL/min/1.73 m 2. Patients already on the required metformin HCl dose (N=1009) were randomized after completing a 2-week, single-blind, placebo run-in period. Patients taking less than the required metformin HCl dose or patients on metformin HCl in combination with another antihyperglycemic agent (N=275) were switched to metformin HCl monotherapy (at doses described above) for at least 8 weeks before entering the 2-week, single-blind, placebo run-in. After the placebo run-in period, patients were randomized to canagliflozin 100 mg, canagliflozin 300 mg, sitagliptin 100 mg, or placebo, administered once daily as add-on therapy to metformin HCl.

At the end of treatment, canagliflozin 100 mg and 300 mg once daily resulted in a statistically significant improvement in HbA 1C(p<0.001 for both doses) compared to placebo when added to metformin HCl. Canagliflozin 100 mg and 300 mg once daily also resulted in a greater proportion of patients achieving an HbA 1Cless than 7%, in significant reduction in fasting plasma glucose (FPG), in improved postprandial glucose (PPG), and in percent body weight reduction compared to placebo when added to metformin HCl (see Table 14). Statistically significant (p<0.001 for both doses) mean changes from baseline in systolic blood pressure relative to placebo were -5.4 mmHg and -6.6 mmHg with canagliflozin 100 mg and 300 mg, respectively.

Canagliflozin Compared to Glimepiride, Both as Add-on Combination Therapy with Metformin HCl

A total of 1,450 patients with type 2 diabetes inadequately controlled on metformin HCl monotherapy (greater than or equal to 2,000 mg/day or at least 1,500 mg/day if higher dose not tolerated) participated in a 52-week, double-blind, active-controlled trial to evaluate the efficacy and safety of canagliflozin in combination with metformin HCl.

The mean age was 56 years, 52% of patients were men, and the mean baseline eGFR was 90 mL/min/1.73 m 2. Patients tolerating maximally required metformin HCl dose (N=928) were randomized after completing a 2-week, single-blind, placebo run-in period. Other patients (N=522) were switched to metformin HCl monotherapy (at doses described above) for at least 10 weeks, then completed a 2-week single-blind run-in period. After the 2-week run-in period, patients were randomized to canagliflozin 100 mg, canagliflozin 300 mg, or glimepiride (titration allowed throughout the 52-week trial to 6 or 8 mg), administered once daily as add-on therapy to metformin HCl.

As shown in Table 15 and Figure 1, at the end of treatment, canagliflozin 100 mg provided similar reductions in HbA 1Cfrom baseline compared to glimepiride when added to metformin HCl therapy. Canagliflozin 300 mg provided a greater reduction from baseline in HbA 1Ccompared to glimepiride, and the relative treatment difference was -0.12% (95% CI: −0.22; −0.02). As shown in Table 15, treatment with canagliflozin 100 mg and 300 mg daily provided greater improvements in percent body weight change, relative to glimepiride.

Canagliflozin as Add-on Combination Therapy with Metformin HCl and Sitagliptin

A total of 217 patients with type 2 diabetes inadequately controlled on the combination of metformin HCl (greater than or equal to 1,500 mg/day) and sitagliptin 100 mg/day (or equivalent fixed-dose combination) participated in a 26-week, double-blind, placebo-controlled trial to evaluate the efficacy and safety of canagliflozin in combination with metformin HCl and sitagliptin. The mean age was 57 years, 58% of patients were men, 73% of patients were Caucasian, 15% were Asian, and 12% were Black or African-American. The mean baseline eGFR was 90 mL/min/1.73 m 2and the mean baseline BMI was 32 kg/m 2. The mean duration of diabetes was 10 years. Eligible patients entered a 2-week, single-blind, placebo run-in period and were subsequently randomized to canagliflozin 100 mg or placebo, administered once daily as add-on to metformin HCl and sitagliptin. Patients with a baseline eGFR of 70 mL/min/1.73 m 2or greater who were tolerating canagliflozin 100 mg and who required additional glycemic control (fasting finger stick 100 mg/dL or greater at least twice within 2 weeks) were up-titrated to canagliflozin 300 mg. While up-titration occurred as early as Week 4, most (90%) patients randomized to canagliflozin were up-titrated to canagliflozin 300 mg by 6 to 8 weeks.

At the end of 26 weeks, canagliflozin once daily resulted in a statistically significant improvement in HbA 1C(p<0.001) compared to placebo when added to metformin HCl and sitagliptin (see Table 16).

Canagliflozin as Add-on Combination Therapy with Metformin HCl and Sulfonylurea

A total of 469 patients with type 2 diabetes inadequately controlled on the combination of metformin HCl (greater than or equal to 2,000 mg/day or at least 1,500 mg/day if higher dose not tolerated) and sulfonylurea (maximal or near-maximal effective dose) participated in a 26-week, double-blind, placebo-controlled trial to evaluate the efficacy and safety of canagliflozin in combination with metformin HCl and sulfonylurea. The mean age was 57 years, 51% of patients were men, and the mean baseline eGFR was 89 mL/min/1.73 m 2. Patients already on the protocol-specified doses of metformin HCl and sulfonylurea (N=372) entered a 2-week, single-blind, placebo run-in period. Other patients (N=97) were required to be on a stable protocol-specified dose of metformin HCl and sulfonylurea for at least 8 weeks before entering the 2-week run-in period. Following the run-in period, patients were randomized to canagliflozin 100 mg, canagliflozin 300 mg, or placebo administered once daily as add-on to metformin HCl and sulfonylurea.

At the end of treatment, canagliflozin 100 mg and 300 mg once daily resulted in a statistically significant improvement in HbA 1C(p<0.001 for both doses) compared to placebo when added to metformin HCl and sulfonylurea. Canagliflozin 100 mg and 300 mg once daily also resulted in a greater proportion of patients achieving an HbA 1Cless than 7.0%, in a significant reduction in fasting plasma glucose (FPG), and in percent body weight reduction compared to placebo when added to metformin HCl and sulfonylurea (see Table 17).

Canagliflozin Compared to Sitagliptin, Both as Add-on Combination Therapy with Metformin HCl and Sulfonylurea

A total of 755 patients with type 2 diabetes inadequately controlled on the combination of metformin HCl (greater than or equal to 2,000 mg/day or at least 1,500 mg/day if higher dose not tolerated) and sulfonylurea (near-maximal or maximal effective dose) participated in a 52 week, double-blind, active-controlled trial to compare the efficacy and safety of canagliflozin 300 mg versus sitagliptin 100 mg in combination with metformin HCl and sulfonylurea. The mean age was 57 years, 56% of patients were men, and the mean baseline eGFR was 88 mL/min/1.73 m 2. Patients already on protocol-specified doses of metformin HCl and sulfonylurea (N=716) entered a 2-week single-blind, placebo run-in period. Other patients (N=39) were required to be on a stable protocol-specified dose of metformin HCl and sulfonylurea for at least 8 weeks before entering the 2-week run-in period. Following the run-in period, patients were randomized to canagliflozin 300 mg or sitagliptin 100 mg as add-on to metformin HCl and sulfonylurea.

As shown in Table 18 and Figure 2, at the end of treatment, canagliflozin 300 mg provided greater HbA 1Creduction compared to sitagliptin 100 mg when added to metformin HCl and sulfonylurea (p<0.05). Canagliflozin 300 mg resulted in a mean percent change in body weight from baseline of -2.5% compared to +0.3% with sitagliptin 100 mg. A mean change in systolic blood pressure from baseline of -5.06 mmHg was observed with canagliflozin 300 mg compared to +0.85 mmHg with sitagliptin 100 mg.

Canagliflozin as Add-on Combination Therapy with Metformin HCl and Pioglitazone

A total of 342 patients with type 2 diabetes inadequately controlled on the combination of metformin HCl (greater than or equal to 2,000 mg/day or at least 1,500 mg/day if higher dose not tolerated) and pioglitazone (30 or 45 mg/day) participated in a 26-week, double--blind, placebo-controlled trial to evaluate the efficacy and safety of canagliflozin in combination with metformin HCl and pioglitazone. The mean age was 57 years, 63% of patients were men, and the mean baseline eGFR was 86 mL/min/1.73 m 2. Patients already on protocol-specified doses of metformin HCl and pioglitazone (N=163) entered a 2-week, single-blind, placebo run-in period. Other patients (N=181) were required to be on stable protocol-specified doses of metformin HCl and pioglitazone for at least 8 weeks before entering the 2-week run-in period. Following the run-in period, patients were randomized to canagliflozin 100 mg, canagliflozin 300 mg, or placebo, administered once daily as add-on to metformin HCl and pioglitazone.

At the end of treatment, canagliflozin 100 mg and 300 mg once daily resulted in a statistically significant improvement in HbA 1C(p<0.001 for both doses) compared to placebo when added to metformin HCl and pioglitazone. Canagliflozin 100 mg and 300 mg once daily also resulted in a greater proportion of patients achieving an HbA 1Cless than 7%, in significant reduction in fasting plasma glucose (FPG), and in percent body weight reduction compared to placebo when added to metformin HCl and pioglitazone (see Table 19). Statistically significant (p<0.05 for both doses) mean changes from baseline in systolic blood pressure relative to placebo were -4.1 mmHg and -3.5 mmHg with canagliflozin 100 mg and 300 mg, respectively.

Canagliflozin as Add-on Combination Therapy with Insulin (With or Without Other Anti-Hyperglycemic Agents, Including Metformin HCl)

A total of 1,718 patients with type 2 diabetes inadequately controlled on insulin greater than or equal to 30 units/day or insulin in combination with other antihyperglycemic agents participated in an 18-week, double-blind, placebo-controlled substudy of a cardiovascular trial to evaluate the efficacy and safety of canagliflozin in combination with insulin. Of these patients, a subgroup of 432 patients with inadequate glycemic control received canagliflozin or placebo plus metformin HCl and ≥ 30 units/day of insulin over 18 weeks.

In this subgroup, the mean age was 61 years, 67% of patients were men, and the mean baseline eGFR was 81 mL/min/1.73 m 2. Patients on metformin HCl in combination with basal, bolus, or basal/bolus insulin for at least 10 weeks entered a 2-week, single-blind, placebo run-in period. Approximately 74% of these patients were on a background of metformin HCl and basal/bolus insulin regimen. After the run-in period, patients were randomized to canagliflozin 100 mg, canagliflozin 300 mg, or placebo, administered once daily as add-on to metformin HCl and insulin. The mean daily insulin dose at baseline was 93 units, which was similar across treatment groups.

At the end of treatment, canagliflozin 100 mg and 300 mg once daily resulted in a statistically significant improvement in HbA 1C(p<0.001 for both doses) compared to placebo when added to metformin HCl and insulin. Canagliflozin 100 mg and 300 mg once daily also resulted in a greater proportion of patients achieving an HbA 1Cless than 7%, in significant reductions in fasting plasma glucose (FPG), and in percent body weight reductions compared to placebo (see Table 20). Statistically significant (p=0.023 for the 100 mg and p<0.001 for the 300 mg dose) mean change from baseline in systolic blood pressure relative to placebo was –3.5 mmHg and -6 mmHg with canagliflozin 100 mg and 300 mg, respectively. Fewer patients on canagliflozin in combination with metformin HCl and insulin required glycemic rescue therapy: 3.6% of patients receiving canagliflozin 100 mg, 2.7% of patients receiving canagliflozin 300 mg, and 6.2% of patients receiving placebo. An increased incidence of hypoglycemia was observed in this trial, which is consistent with the expected increase of hypoglycemia when an agent not associated with hypoglycemia is added to insulin [see Warnings and Precautions (5.6)and Adverse Reactions (6.1)] .

14.2 Canagliflozin Cardiovascular Outcomes in Patients with Type 2 Diabetes Mellitus and Atherosclerotic Cardiovascular Disease


Canagliflozin is indicated to reduce the risk of major adverse cardiovascular events in adults with type 2 diabetes mellitus and established cardiovascular disease (CVD).

The CANVAS and CANVAS-R trials were multicenter, multi-national, randomized, double-blind parallel group, with similar inclusion and exclusion criteria. Patients eligible for enrollment in both CANVAS and CANVAS-R trials were: 30 years of age or older and had established, stable, cardiovascular, cerebrovascular, peripheral artery disease (66% of the enrolled population) or were 50 years of age or older and had two or more other specified risk factors for cardiovascular disease (34% of the enrolled population).

The integrated analysis of the CANVAS and CANVAS-R trials compared the risk of Major Adverse Cardiovascular Event (MACE) between canagliflozin and placebo when these were added to and used concomitantly with standard of care treatments for diabetes and atherosclerotic cardiovascular disease. The primary endpoint, MACE, was the time to first occurrence of a three-part composite outcome which included cardiovascular death, non-fatal myocardial infarction and non-fatal stroke.

In CANVAS, patients were randomly assigned 1:1:1 to canagliflozin 100 mg, canagliflozin 300 mg, or matching placebo. In CANVAS-R, patients were randomly assigned 1:1 to canagliflozin 100 mg or matching placebo, and titration to 300 mg was permitted at the investigator's discretion (based on tolerability and glycemic needs) after Week 13. Concomitant antidiabetic and atherosclerotic therapies could be adjusted, at the discretion of investigators, to ensure participants were treated according to the standard care for these diseases.

A total of 10,134 patients were treated (4,327 in CANVAS and 5,807 in CANVAS-R; total of 4,344 randomly assigned to placebo and 5,790 to canagliflozin) for a mean exposure duration of 149 weeks (223 weeks [4.3 years] in CANVAS and 94 weeks [1.8 years] in CANVAS-R) .Approximately 78% of the trial population was Caucasian, 13% was Asian, and 3% was Black. The mean age was 63 years and approximately 64% were male.

The mean HbA 1Cat baseline was 8.2% and mean duration of diabetes was 13.5 years with 70% of patients having had diabetes for 10 years or more. Approximately 31%, 21% and 17% reported a past history of neuropathy, retinopathy and nephropathy, respectively, and the mean eGFR 76 mL/min/1.73 m 2. At baseline, patients were treated with one (19%) or more (80%) antidiabetic medications including metformin (77%), insulin (50%), and sulfonylurea (43%).

At baseline, the mean systolic blood pressure was 137 mmHg, the mean diastolic blood pressure was 78 mmHg, the mean LDL was 89 mg/dL, the mean HDL was 46 mg/dL, and the mean urinary albumin to creatinine ratio (UACR) was 115 mg/g. At baseline, approximately 80% of patients were treated with renin angiotensin system inhibitors, 53% with beta-blockers, 13% with loop diuretics, 36% with non-loop diuretics, 75% with statins, and 74% with antiplatelet agents (mostly aspirin). During the trial, investigators could modify anti-diabetic and cardiovascular therapies to achieve local standard of care treatment targets with respect to blood glucose, lipid, and blood pressure. More patients receiving canagliflozin compared to placebo initiated anti-thrombotics (5.2% vs 4.2%) and statins (5.8% vs 4.8%) during the trial.

For the primary analysis, a stratified Cox proportional hazards model was used to test for non-inferiority against a pre-specified risk margin of 1.3 for the hazard ratio of MACE.

In the integrated analysis of CANVAS and CANVAS-R trials, canagliflozin reduced the risk of first occurrence of MACE. The estimated hazard ratio (95% CI) for time to first MACE was 0.86 (0.75, 0.97). Refer to Table 21. Vital status was obtained for 99.6% of patients across the trials. The Kaplan-Meier curve depicting time to first occurrence of MACE is shown in Figure 3.

Canagliflozin is indicated to reduce the risk of end-stage kidney disease (ESKD), doubling of serum creatinine, cardiovascular (CV) death, and hospitalization for heart failure in adults with type 2 diabetes mellitus and diabetic nephropathy with albuminuria > 300 mg/day.

The Canagliflozin and Renal Events in Diabetes with Established Nephropathy Clinical Evaluation Trial (CREDENCE) was a multinational, randomized, double-blind, placebo-controlled trial comparing canagliflozin with placebo in patients with type 2 diabetes mellitus, an eGFR ≥ 30 to < 90 mL/min/1.73 m 2and albuminuria (urine albumin/creatinine ˃ 300 to ≤ 5000 mg/g) who were receiving standard of care including a maximum-tolerated, labeled daily dose of an angiotensin-converting enzyme inhibitor (ACEi) or angiotensin receptor blocker (ARB).

The primary objective of CREDENCE was to assess the efficacy of canagliflozin relative to placebo in reducing the composite endpoint of end stage kidney disease (ESKD), doubling of serum creatinine, and renal or CV death.

Patients were randomized to receive canagliflozin 100 mg (N=2,202) or placebo (N=2,199) and treatment was continued until the initiation of dialysis or renal transplantation.

The median follow-up duration for the 4,401 randomized subjects was 137 weeks. Vital status was obtained for 99.9% of subjects.

The population was 67% White, 20% Asian, and 5% Black; 32% were of Hispanic or Latino ethnicity. The mean age was 63 years and 66% were male.

At randomization, the mean HbA 1cwas 8.3%, the median urine albumin/creatinine was 927 mg/g, the mean eGFR was 56.2 mL/min/1.73 m 2, 50% had prior CV disease, and 15% reported a history of heart failure. The most frequent antihyperglycemic agents (AHA) medications used at baseline were insulin (66%), biguanides (58%), and sulfonylureas (29%). Nearly all subjects (99.9%) were on ACEi or ARB at randomization, approximately 60% were taking an anti-thrombotic agent (including aspirin), and 69% were on a statin.

The primary composite endpoint in the CREDENCE study was the time to first occurrence of ESKD (defined as an eGFR < 15 mL/min/1.73 m 2, initiation of chronic dialysis or renal transplant), doubling of serum creatinine, and renal or CV death. Canagliflozin 100 mg significantly reduced the risk of the primary composite endpoint based on a time-to-event analysis [HR: 0.70; 95% CI: 0.59, 0.82; p<0.0001] (see Figure 4). The treatment effect reflected a reduction in progression to ESKD, doubling of serum creatinine and cardiovascular death as shown in Table 22 and Figure 4. There were few renal deaths during the trial. Canagliflozin 100 mg also significantly reduced the risk of hospitalization for heart failure [HR: 0.61; 95% CI: 0.47 to 0.80; p<0.001].

Medication Guide INVOKAMET ®(in vok' a met) (canagliflozin and metformin hydrochloride (HCl)) tablets, for oral use and INVOKAMET ®(in vok' a met) XR (canagliflozin and metformin HCl) extended-release tablets, for oral use
This Medication Guide has been approved by the U.S. Food and Drug Administration. Revised 01/2024
What is the most important information I should know about INVOKAMET or INVOKAMET XR? INVOKAMET and INVOKAMET XR can cause serious side effects, including:
  • Lactic Acidosis.Metformin, one of the medicines in INVOKAMET and INVOKAMET XR, can cause a rare but serious condition called lactic acidosis (a build-up of lactic acid in the blood) that can cause death. Lactic acidosis is a medical emergency and must be treated in the hospital. Stop taking INVOKAMET or INVOKAMET XR and call your doctor right away if you have any of the following symptoms of lactic acidosis:
  • feel cold in your hands or feet
  • feel very weak or tired
  • have trouble breathing
  • have stomach pains, nausea, or vomiting
  • have a slow or irregular heartbeat
  • have unusual (not normal) muscle pain
  • have unusual sleepiness or sleep longer than usual
  • feel dizzy or lightheaded

Most people who have had lactic acidosis had other conditions that, in combination with metformin use, led to the lactic acidosis. Tell your doctor if you have any of the following, because you have a higher chance for getting lactic acidosis with INVOKAMET or INVOKAMET XR if you:
  • have severe kidney problems or your kidneys are affected by certain x-ray tests that use injectable dye.
  • have liver problems.
  • drink alcohol very often or drink a lot of alcohol in short-term "binge" drinking.
  • get dehydrated (lose a large amount of body fluids). This can happen if you are sick with a fever, vomiting, or diarrhea. Dehydration can also happen when you sweat a lot with activity or exercise and do not drink enough fluids.
  • have surgery.
  • have a heart attack, severe infection, or stroke.
  • are 65 years of age or older.

The best way to keep from having a problem with lactic acidosis from metformin is to tell your doctor if you have any of the problems in the ul above. Your doctor will decide to stop your INVOKAMET or INVOKAMET XR for a while if you have any of these things.
  • Diabetic ketoacidosis (increased ketones in your blood or urine) in people with type 1 and other ketoacidosis.INVOKAMET and INVOKAMET XR can cause ketoacidosis that can be life-threatening and may lead to death. Ketoacidosis is a serious condition which needs to be treated in a hospital. People with type 1 diabetes have a high risk of getting ketoacidosis. People with type 2 diabetes or pancreas problems also have an increased risk of getting ketoacidosis. Ketoacidosis can also happen in people who: are sick, cannot eat or drink as usual, skip meals, are on a diet high in fat and low in carbohydrates (ketogenic diet), take less than the usual amount of insulin or miss insulin doses, drink too much alcohol, have a loss of too much fluid from the body (volume depletion), or who have surgery. Ketoacidosis can happen even if your blood sugar is less than 250 mg/dL. Your healthcare provider may ask you to periodically check ketones in your urine or blood.
  • Stop taking INVOKAMET or INVOKAMET XR and call your healthcare provider or get medical help right away if you get any of the following. If possible, check for ketones in your urine or blood, even if your blood sugar is less than 250 mg/dL:
  • nausea
  • vomiting
  • stomach-area (abdominal) pain
  • tiredness
  • trouble breathing
  • ketones in your urine or blood
  • Amputations. INVOKAMET or INVOKAMET XR may increase your risk of lower limb amputations. Amputations mainly involve removal of the toe or part of the foot, however, amputations involving the leg, below and above the knee, have also occurred. Some people had more than one amputation, some on both sides of the body. You may be at a higher risk of lower limb amputation if you:
    • have a history of amputation
    • have heart disease or are at risk for heart disease
    • have had blocked or narrowed blood vessels, usually in your leg
    • have damage to the nerves (neuropathy) in your leg
    • have had diabetic foot ulcers or sores

Call your doctor right away if you have new pain or tenderness, any sores, ulcers, or infections in your leg or foot.Your doctor may decide to stop your INVOKAMET or INVOKAMET XR for a while if you have any of these signs or symptoms.

Talk to your doctor about proper foot care.
  • Dehydration. INVOKAMET or INVOKAMET XR can cause some people to become dehydrated (the loss of too much body water). Dehydration may cause you to feel dizzy, faint, lightheaded, or weak, especially when you stand up (orthostatic hypotension). There have been reports of sudden worsening of kidney function in people with type 2 diabetes who are taking canagliflozin, one of the medicines in INVOKAMET and INVOKAMET XR. You may be at higher risk of dehydration if you:
    • take medicines to lower your blood pressure, including diuretics (water pill)
    • are on a low sodium (salt) diet
    • have kidney problems
    • are 65 years of age or older

Talk to your doctor about what you can do to prevent dehydration including how much fluid you should drink on a daily basis. Call your healthcare provider right away if you reduce the amount of food or liquid you drink, for example if you cannot eat or you start to lose liquids from your body, for example from vomiting, diarrhea, or being in the sun too long.
  • Vaginal yeast infection.Symptoms of a vaginal yeast infection include:
    • vaginal odor
    • white or yellowish vaginal discharge (discharge may be lumpy or look like cottage cheese)
    • vaginal itching
  • Yeast infection of the skin around the penis (balanitis or balanoposthitis).Swelling of an uncircumcised penis may develop that makes it difficult to pull back the skin around the tip of the penis. Other symptoms of yeast infection of the penis include:
  • redness, itching, or swelling of the penis
  • foul smelling discharge from the penis
  • rash of the penis
  • pain in the skin around the penis
Talk to your doctor about what to do if you get symptoms of a yeast infection of the vagina or penis. Your doctor may suggest you use an over-the-counter antifungal medicine. Talk to your doctor right away if you use an over-the-counter antifungal medication and your symptoms do not go away.
INVOKAMET or INVOKAMET XR can have other serious side effects.See " What are the possible side effects of INVOKAMET or INVOKAMET XR?"

What is INVOKAMET or INVOKAMET XR?
  • INVOKAMET contains 2 prescription medicines called canagliflozin (INVOKANA) and metformin HCl (GLUCOPHAGE). INVOKAMET XR contains 2 prescription medicines called canagliflozin (INVOKANA) and metformin. INVOKAMET or INVOKAMET XR can be used:
    • along with diet and exercise to lower blood sugar (glucose) in adults with type 2 diabetes.

What are the possible side effects of INVOKAMET or INVOKAMET XR?

INVOKAMET or INVOKAMET XR may cause serious side effects including:
  • See " What is the most important information I should know about INVOKAMET or INVOKAMET XR?"
  • serious urinary tract infections.Serious urinary tract infections that may lead to hospitalization have happened in people who are taking canagliflozin, one of the medicines in INVOKAMET and INVOKAMET XR. Tell your doctor if you have any signs or symptoms of a urinary tract infection such as a burning feeling when passing urine, a need to urinate often, the need to urinate right away, pain in the lower part of your stomach (pelvis), or blood in the urine. Sometimes people may also have a fever, back pain, nausea, or vomiting.
  • low blood sugar (hypoglycemia).If you take INVOKAMET or INVOKAMET XR with another medicine that can cause low blood sugar, such as a sulfonylurea or insulin, your risk of getting low blood sugar is higher. The dose of your sulfonylurea medicine or insulin may need to be lowered while you take INVOKAMET or INVOKAMET XR. Signs and symptoms of low blood sugar may include:
  • headache
  • confusion
  • hunger
  • shaking or feeling jittery
  • drowsiness
