Embryo-Fetal Toxicity: Can cause fetal harm. Advise females of reproductive potential of the potential risk to a fetus and to use effective contraception. (5.6, 8.1, 8.3)

5.1Myelosuppression

Thrombocytopenia, neutropenia, and anemia have occurred in patients receiving SCEMBLIX. Thrombocytopenia occurred in 156 of 556 (28%) patients receiving SCEMBLIX, with Grade 3 or 4 thrombocytopenia reported in 39 (7%) and 53 (10%) of patients, respectively. Among the patients with Grade 3 or 4 thrombocytopenia, median time to first occurrence of events was 6 weeks (range, 0.1 to 64 weeks). SCEMBLIX was permanently discontinued in 11 (2%) patients, while it was temporarily withheld in 70 (13%) patients due to thrombocytopenia.

Neutropenia occurred in 120 (22%) patients receiving SCEMBLIX, with Grade 3 and 4 neutropenia reported in 41 (7%) and 35 (6%) patients, respectively. Among the patients with Grade 3 or 4 neutropenia, median time to first occurrence of events was 7 weeks (range, 0.1 to 180 weeks). SCEMBLIX was permanently discontinued in 7 (1.3%) patients, while it was temporarily withheld in 52 (9%) patients due to neutropenia.

Anemia occurred in 70 (13%) patients receiving SCEMBLIX, with Grade 3 anemia occurring in 22 (4%) patients. Among the patients with Grade 3 or 4 anemia, median time to first occurrence of events was 22 weeks (range, 0.1 to 207 weeks). SCEMBLIX was temporarily withheld in 2 (0.4%) patients due to anemia [see Adverse Reactions (6.1)].

Perform complete blood counts every two weeks for the first 3 months of treatment and monthly thereafter or as clinically indicated. Monitor patients for signs and symptoms of myelosuppression.

Based on the severity of thrombocytopenia and/or neutropenia, reduce dose, temporarily withhold, or permanently discontinue SCEMBLIX [see Dosage and Administration (2.4)].

5.2Pancreatic Toxicity

Pancreatitis occurred in 11 of 556 (2%) patients receiving SCEMBLIX, with Grade 3 pancreatitis occurring in 6 (1.1%) patients. SCEMBLIX was permanently discontinued in three (0.5%) patients, while it was temporarily withheld in 6 (1.1%) patients due to pancreatitis. Elevation of serum lipase and amylase occurred in 107 of 556 (19%) patients receiving SCEMBLIX, with Grade 3 and Grade 4 pancreatic enzyme elevations occurring in 41 (7%) and 11 (2%) patients, respectively. SCEMBLIX was permanently discontinued in 11 (2%) patients due to the elevation of serum lipase and amylase [see Adverse Reactions (6.1)].

Assess serum lipase and amylase levels monthly during treatment with SCEMBLIX, or as clinically indicated. Monitor patients for signs and symptoms of pancreatic toxicity. Perform more frequent monitoring in patients with a history of pancreatitis. If lipase and amylase elevation are accompanied by abdominal symptoms, temporarily withhold SCEMBLIX and consider appropriate diagnostic tests to exclude pancreatitis [see Dosage and Administration (2.4)].

Based on the severity of lipase and amylase elevation, reduce dose, temporarily withhold, or permanently discontinue SCEMBLIX [see Dosage and Administration (2.4)].

5.3Hypertension

Hypertension occurred in 90 of 556 (16%) patients receiving SCEMBLIX, with Grade 3 or 4 hypertension reported in 49 (9%) and 1 (0.2%) patients, respectively. Among the patients with Grade 3 or 4 hypertension, median time to first occurrence was 32 weeks (range, 0.1 to 365 weeks). SCEMBLIX was temporarily withheld in 5 (0.9%) patients due to hypertension [see Adverse Reactions (6.1)].

Monitor and manage hypertension using standard antihypertensive therapy during treatment with SCEMBLIX as clinically indicated; for Grade 3 or higher hypertension, temporarily withhold, reduce dose, or permanently discontinue SCEMBLIX depending on persistence of hypertension [see Dosage and Administration (2.4)].

5.4Hypersensitivity

Hypersensitivity occurred in 168 of 556 (30%) patients receiving SCEMBLIX, with Grade 3 or 4 hypersensitivity reported in 7 (1.3%) patients [see Adverse Reactions (6.1)]. Reactions included rash, edema, and bronchospasm. Monitor patients for signs and symptoms of hypersensitivity and initiate appropriate treatment as clinically indicated; for Grade 3 or higher hypersensitivity, temporarily withhold, reduce dose, or permanently discontinue SCEMBLIX depending on persistence of hypersensitivity [see Dosage and Administration (2.4)].

5.5Cardiovascular Toxicity

Cardiovascular toxicity (including ischemic cardiac and CNS conditions, arterial thrombotic and embolic conditions) and cardiac failure occurred in 60 (11%) and in 13 (2.3%) of 556 patients receiving SCEMBLIX, respectively [see Adverse Reactions (6.1)]. Grade 3 cardiovascular toxicity was reported in 14 (2.5%) patients, while Grade 3 cardiac failure was observed in 5 (0.9%) patients. Grade 4 cardiovascular toxicity occurred in 4 (0.7%) patients, with fatalities occurring in 4 (0.7%) patients. Grade 4 cardiac failure was reported in 1 (0.2%) patient with fatality occurring in 1 (0.2%) patient. Permanent discontinuation of SCEMBLIX occurred in 4 (0.7%) patients due to cardiovascular toxicity and in 1 (0.2%) patient due to cardiac failure, respectively. In the majority of patients, cardiovascular toxicity occurred in patients with preexisting cardiovascular conditions or risk factors, and/or prior exposure to multiple TKIs.

Arrhythmia, including QTc prolongation, occurred in 35 of 556 (6%) patients receiving SCEMBLIX, with Grade 3 or 4 arrhythmia reported in 10 (1.8%) and 2 (0.4%) patients, respectively. QTc prolongation occurred in 5 of 556 (0.9%) patients receiving SCEMBLIX, with Grade 3 QTc prolongation reported in 2 (0.4%) patients [see Adverse Reactions (6.1)].

Monitor patients with history of cardiovascular risk factors for cardiovascular signs and symptoms. Initiate appropriate treatment as clinically indicated; for Grade 3 or higher cardiovascular toxicity, temporarily withhold, reduce dose, or permanently discontinue SCEMBLIX depending on persistence of cardiovascular toxicity [see Dosage and Administration (2.4)].

5.6Embryo-Fetal Toxicity

Based on findings from animal studies and its mechanism of action, SCEMBLIX can cause fetal harm when administered to a pregnant woman. In animal reproduction studies, administration of asciminib to pregnant rats and rabbits during the period organogenesis caused adverse developmental outcomes, including embryo-fetal mortality and malformations at maternal exposures (AUC) equivalent to or less than those in patients at the recommended doses. Advise pregnant women and females of reproductive potential of the potential risk to a fetus if SCEMBLIX is used during pregnancy or if the patient becomes pregnant while taking SCEMBLIX. Verify the pregnancy status of females of reproductive potential prior to starting treatment with SCEMBLIX. Females of reproductive potential should use effective contraception during treatment with SCEMBLIX and for 1 week after the last dose [see Use in Specific Populations (8.1, 8.3)].

Adverse Reactions in Patients with Ph+ CML-CP with the T315I Mutation

The single-arm clinical trial enrolled patients with Ph+ CML-CP with the T315I mutation [see Clinical Studies (14.3)]. The safety population (received at least 1 dose of SCEMBLIX) included 48 patients with Ph+ CML-CP with the T315I mutation who received 200 mg of SCEMBLIX twice daily. Among these patients, 83% were exposed for 24 weeks or longer, and 75% were exposed for 48 weeks or longer.

Serious adverse reactions occurred in 23% of patients who received SCEMBLIX. Serious adverse reactions in > 1% included abdominal pain (4.2%), vomiting (4.2%), pneumonia (4.2%), musculoskeletal pain (2.1%), headache (2.1%), hemorrhage (2.1%), constipation (2.1%), arrhythmia (2.1%), and pleural effusion (2.1%).

Permanent discontinuation of SCEMBLIX due to an adverse reaction occurred in 10% of patients. Adverse reactions which resulted in permanent discontinuation of SCEMBLIX in > 2% of patients included pancreatic enzymes increased (2.1%).

Dosage interruptions of SCEMBLIX due to an adverse reaction occurred in 31% of patients. Adverse reactions which required dosage interruption in > 5% of patients included pancreatic enzymes increased (17%) and thrombocytopenia (8%).

Dose reductions of SCEMBLIX due to an adverse reaction occurred in 23% of patients. Adverse reactions which required dose reductions in > 1% of patients included pancreatic enzymes increased (10%), abdominal pain (4.2%), anemia (2.1%), blood bilirubin increased (2.1%), dizziness (2.1%), fatigue (2.1%), hepatic enzymes increased (2.1%), musculoskeletal pain (2.1%), nausea (2.1%), neutropenia (2.1%), pruritus (2.1%), and thrombocytopenia (2.1%).

The most common (≥ 20%) adverse reactions in patients who received SCEMBLIX were musculoskeletal pain, fatigue, nausea, rash, and diarrhea.

The most common select laboratory abnormalities that worsened from baseline in ≥ 20% of patients who received SCEMBLIX were alanine aminotransferase (ALT) increased, lipase increased, triglycerides increased, hemoglobin decreased, neutrophil count decreased, lymphocyte count decreased, phosphate decreased, aspartate aminotransferase (AST) increased, amylase increased, platelet count decreased, and bilirubin increased.

7.1Effect of Other Drugs on SCEMBLIX

Strong CYP3A4 Inhibitors

Asciminib is a CYP3A4 substrate. Concomitant use of SCEMBLIX with a strong CYP3A4 inhibitor increases both the asciminib C_max and AUC, which may increase the risk of adverse reactions [see Clinical Pharmacology (12.3)]. Closely monitor for adverse reactions in patients treated with SCEMBLIX at 200 mg twice daily with concomitant use of strong CYP3A4 inhibitors.

Itraconazole Oral Solution Containing Hydroxypropyl-β-cyclodextrin

Concomitant use of SCEMBLIX with itraconazole oral solution containing hydroxypropyl-β-cyclodextrin decreases asciminib C_max and AUC, which may reduce SCEMBLIX efficacy [see Clinical Pharmacology (12.3)]. Avoid coadministration of SCEMBLIX at all recommended doses with itraconazole oral solution containing hydroxypropyl-β-cyclodextrin.

7.2Effect of SCEMBLIX on Other Drugs

Certain CYP3A4 Substrates

Asciminib is a CYP3A4 inhibitor. Concomitant use of SCEMBLIX increases the C_max and AUC of CYP3A4 substrates, which may increase the risk of adverse reactions of these substrates [see Clinical Pharmacology (12.3)].

Closely monitor for adverse reactions in patients treated with SCEMBLIX at 80 mg total daily dose with concomitant use of certain CYP3A4 substrates, where minimal concentration changes may lead to serious adverse reactions. Avoid coadministration of SCEMBLIX at 200 mg twice daily with certain CYP3A4 substrates, where minimal concentration changes may lead to serious adverse reactions.

CYP2C9 Substrates

Asciminib is a CYP2C9 inhibitor. Concomitant use of SCEMBLIX increases the C_max and AUC of CYP2C9 substrates, which may increase the risk of adverse reactions of these substrates [see Clinical Pharmacology (12.3)].

Avoid coadministration of SCEMBLIX at 80 mg total daily dose with certain CYP2C9 substrates, where minimal concentration changes may lead to serious adverse reactions. If coadministration is unavoidable, reduce the CYP2C9 substrate dosage as recommended in its prescribing information.

Avoid coadministration of SCEMBLIX at 200 mg twice daily with sensitive CYP2C9 substrates and certain CYP2C9 substrates, where minimal concentration changes may lead to serious adverse reactions. If coadministration is unavoidable, consider alternative therapy with a non-CYP2C9 substrate.

Certain P-gp Substrates

Asciminib is a P-gp inhibitor. Concomitant use of SCEMBLIX increases the plasma concentrations of P-gp substrates, which may increase the risk of adverse reactions of these substrates [see Clinical Pharmacology (12.3)].

Closely monitor for adverse reactions in patients treated with SCEMBLIX at all recommended doses with concomitant use of P-gp substrates, where minimal concentration changes may lead to serious toxicities.

Substrates of OATP1B or BCRP

Asciminib is an OATP1B and BCRP inhibitor. The effect of concomitant use of SCEMBLIX with OATP1B and BCRP substrates has not been established in clinical studies. However, based upon a mechanistic understanding of the elimination of asciminib and its in vitro inhibitory potential [see Clinical Pharmacology (12.3)], concomitant use of SCEMBLIX increases the C_max and AUC of OATP1B and BCRP substrates, which may increase the risk of adverse reactions of these substrates.

Avoid coadministration of SCEMBLIX at all recommended doses with rosuvastatin and atorvastatin. Closely monitor for adverse reactions in patients treated with SCEMBLIX at all recommended doses with concomitant use of other OATP1B or BCRP substrates. Reduce the dosage of the other OATP1B or BCRP substrates as recommended in their Prescribing Information when used concomitantly with SCEMBLIX at all recommended doses.

8use In Specific Populations

Lactation: Advise not to breastfeed. (8.2)

8.1Pregnancy

Risk Summary

Based on findings from animal studies and the mechanism of action, SCEMBLIX can cause embryo-fetal harm when administered to a pregnant woman [see Clinical Pharmacology (12.1)]. There are no available data on SCEMBLIX use in pregnant women to evaluate a drug-associated risk.

Animal reproduction studies in pregnant rats and rabbits demonstrated that oral administration of asciminib during organogenesis induced structural abnormalities, embryo-fetal mortality, and alterations to growth (see Data).

Advise pregnant women and females of reproductive potential of the potential risk to a fetus.

In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.

Data

Animal Data

In embryo-fetal development studies, pregnant animals received oral doses of asciminib at 25, 150, and 600 mg/kg/day in rats and at 15, 50, and 300 mg/kg/day in rabbits during the period of organogenesis.

In rats, maternal toxicity at the asciminib dose of 600 mg/kg/day resulted in the early termination of the dose group; a complete embryo-fetal examination was not conducted for this group. Adverse embryo-fetal findings were observed at 25 and 150 mg/kg; these doses did not cause maternal toxicities. Increases in fetal weights at 25 and 150 mg/kg/day were observed, which may be related to increased ossification (i.e., increased rate of development). Malformations were evident at 150 mg/kg and included cleft palate, anasarca (edema), and cardiac abnormalities. Additional fetal findings included urinary tract and skeletal variations, observed primarily at 150 mg/kg/day. At the dose of 25 mg/kg/day, the area under the curve (AUC) exposures were equivalent to or below those achieved in patients at the 40 mg twice daily or 80 mg once daily doses, respectively. At the dose of 25 mg/kg/day, the AUC exposures were below those achieved in patients at the 200 mg twice daily dose.

In rabbits, maternal toxicities at the asciminib dose of 300 mg/kg/day resulted in the early termination of the dose group; a complete embryo-fetal examination was not conducted for this group. Adverse embryo-fetal findings were observed at 50 mg/kg; this dose did not cause maternal toxicities. Findings at the 50 mg/kg dose included increases in early resorptions and post-implantation loss, decreases in the number of live fetuses, and cardiac malformations. At the dose of 50 mg/kg/day, the AUC exposures were 4-fold those achieved in patients at the 40 mg twice daily or 80 mg once daily doses. At the dose of 50 mg/kg/day, the AUC exposures were below those achieved in patients at the 200 mg twice daily dose.

8.2Lactation

Risk Summary

There are no data on the presence of asciminib or its metabolites in human milk, the effects on the breastfed child, or milk production.

Because of the potential for serious adverse reactions in the breastfed child, advise women not to breastfeed during treatment with SCEMBLIX and for 1 week after the last dose.

8.3Females and Males of Reproductive Potential

Based on findings from animal studies, SCEMBLIX can cause embryo-fetal harm when administered to a pregnant woman [see Use in Specific Populations (8.1)].

Pregnancy Testing

Verify the pregnancy status of females of reproductive potential prior to starting treatment with SCEMBLIX.

Contraception

Females

Females of reproductive potential should use effective contraception during treatment with SCEMBLIX and for 1 week after the last dose.

Infertility

Based on findings in animals, SCEMBLIX may impair fertility in females of reproductive potential [see Nonclinical Toxicology (13.1)]. The reversibility of the effect on fertility is unknown.

8.4Pediatric Use

The safety and efficacy of SCEMBLIX in pediatric patients have not been established.

8.5Geriatric Use

Among the 556 patients receiving SCEMBLIX in the ASC4FIRST, ASCEMBL and X2101 studies, 130 (23%) were 65 years of age and older and 31 (6%) were 75 years of age and older.

Overall, no differences in safety or efficacy of SCEMBLIX were observed between patients 65 years of age and older compared to younger patients.

8.6Renal Impairment

No dose adjustment is required for patients with mild to severe renal impairment (estimated glomerular filtration rate [eGFR] 15 to 89 mL/min/1.73 m²) and not requiring dialysis receiving SCEMBLIX [see Clinical Pharmacology (12.3)].

8.7Hepatic Impairment

No dose adjustment is required for patients with mild [total bilirubin ≤ upper limit of normal (ULN) and aspartate aminotransferase (AST) > ULN or total bilirubin > 1 to 1.5 times ULN and any AST] to severe hepatic impairment (total bilirubin > 3 times ULN and any AST) receiving SCEMBLIX [see Clinical Pharmacology (12.3)].

11description

SCEMBLIX (asciminib) is a kinase inhibitor. The chemical name of the drug substance is N-[4-(Chlorodifluoromethoxy)phenyl]-6-[(3R)-3-hydroxypyrrolidin-1-yl]-5-(1H-pyrazol-3-yl)pyridine-3-carboxamide-hydrogen chloride (1/1). Asciminib hydrochloride is a white to slightly yellow powder. The molecular formula of asciminib hydrochloride is C₂₀H₁₈ClF₂N₅O₃.HCl, and the relative molecular mass is 486.30 g/mol for the hydrochloride salt and 449.84 g/mol for the free base. The chemical structure of asciminib hydrochloride is shown below:

SCEMBLIX film-coated tablets are supplied for oral use with three strengths that contain 20 mg, 40 mg and 100 mg of asciminib (equivalent to 21.62 mg, 43.24 mg and 108.10 mg, respectively, of asciminib hydrochloride). The tablets contain colloidal silicon dioxide, croscarmellose sodium, ferric oxide, hydroxypropyl cellulose, lactose monohydrate, lecithin, magnesium stearate, microcrystalline cellulose, polyvinyl alcohol, talc, titanium dioxide, and xanthan gum. The 20 mg tablets contain ferric oxide, yellow and ferric oxide, red. The 40 mg and 100 mg tablets contain ferrosoferric oxide and ferric oxide, red.

12clinical Pharmacology

12.1Mechanism of Action

Asciminib is an ABL/BCR-ABL1 tyrosine kinase inhibitor. Asciminib inhibits the ABL1 kinase activity of the BCR::ABL1 fusion protein, by binding to the ABL myristoyl pocket. In studies conducted in vitro or in animal models of CML, asciminib showed activity against wild-type BCR::ABL1 and several mutant forms of the kinase, including the T315I mutation.

12.2Pharmacodynamics

Exposure-Response Relationships

Over asciminib dosages of 10 mg to 200 mg twice daily (0.25 to 5 times the recommended 80 mg daily dosage), a lower exposure was associated with a smaller decrease in BCR::ABL1 level and a lower MMR rate at Week 24.

Over asciminib dosages of 10 mg to 280 mg twice daily (0.25 to 7 times the recommended 80 mg daily dosage), a higher exposure was associated with slightly higher incidence of some adverse reactions (e.g., Grade ≥ 3 lipase increase, Grade ≥ 3 hemoglobin decrease, Grade ≥ 2 ALT increase, Grade ≥ 2 AST increase, Grade ≥ 2 bilirubin increase, and any grade lipase increase).

Cardiac Electrophysiology

Asciminib does not cause a large mean increase in QTc interval (i.e., > 20 msec) at the maximum recommended clinical dosage (200 mg twice daily). Based on available clinical data, small mean QTc increase (< 10 msec) cannot be excluded.

12.3Pharmacokinetics

Asciminib steady-state exposure (AUC and C_max) increase slightly more than dose proportional across the dose range of 10 to 200 mg (0.25 to 5 times the recommended 80 mg daily dosage) administered once or twice daily.

Pharmacokinetic parameters are presented as geometric mean (CV%) unless otherwise stated. The steady state C_max and AUC_tau of asciminib at recommended dosages are uled in Table 9.

Table 9: Steady State^a Asciminib Exposure at Recommended Dosages
^aSteady state is achieved within 3 days. ^bAUC_tau represents AUC_0-12h for twice daily dosing and AUC_0-24h for once daily dosing.

Asciminib dosage C_max (ng/mL) AUC_tau ^b (ng*h/mL) Accumulation ratio

80 mg once daily 1781 (23%) 15112 (28%) 1.30

40 mg twice daily 793 (49%) 5262 (48%) 1.65

200 mg twice daily 5642 (40%) 37547 (41%) 1.92

Absorption

The median (range) T_max of asciminib is 2.5 hours (2 to 3 hours).

Effect of Food

The AUC and C_max of asciminib decreased by 62% and 68%, respectively, with a high-fat meal (1000 calories, 50% fat) and by 30% and 35%, respectively, with a low-fat meal (400 calories, 25% fat) compared to the fasted state following administration of SCEMBLIX.

Distribution

The apparent volume of distribution of asciminib at steady state is 151 L (135%). Asciminib is the main circulating component in plasma (93% of the administered dose).

Asciminib is 97% bound to human plasma proteins in vitro.

Elimination

The total apparent clearance of asciminib is 6.7 L/hour (48%) at 40 mg twice daily and 80 mg once daily, and 4.1 L/hour (38%) at 200 mg twice daily. The terminal elimination half-life of asciminib is 5.5 hours (38%) at 40 mg twice daily and 80 mg once daily, and 9.0 hours (33%) at 200 mg twice daily.

Metabolism

Asciminib is metabolized by CYP3A4-mediated oxidation, UGT2B7- and UGT2B17-mediated glucuronidation.

Excretion

Eighty percent (57% as unchanged) and 11% (2.5% as unchanged) of the asciminib dose were recovered in the feces and in the urine of healthy subjects, respectively, following oral administration of a single 80 mg dose of radio-labeled asciminib.

Asciminib is eliminated by biliary secretion via breast cancer-resistant protein (BCRP).

Specific Populations

No clinically significant differences in the pharmacokinetics of asciminib were observed based on sex, age (20 to 88 years), race (Asian 20%, White 70%, Black/African American 4%), or body weight (42-184 kg), mild to moderate renal impairment (eGFR 30 to 89 mL/min/1.73 m²), or mild (total bilirubin ≤ ULN and AST > ULN or total bilirubin > 1 to 1.5 times ULN and any AST) to moderate (total bilirubin > 1.5 to 3 times ULN and any AST) hepatic impairment.

Patients with Renal Impairment

Asciminib AUC_inf and C_max are increased by 57% and 6%, respectively, in subjects with eGFR between 13 to < 30 mL/min/1.73 m² and not requiring dialysis compared to subjects with normal renal function (eGFR ≥ 90 mL/min/1.73 m²) following oral administration of a single 40 mg dose of SCEMBLIX. The exposure changes in patients with severe renal impairment are not considered clinically meaningful.

Patients with Hepatic Impairment

Asciminib AUC_inf and C_max are increased by 33% and 4%, respectively, in subjects with severe hepatic impairment (total bilirubin > 3 times ULN and any AST), compared to subjects with normal hepatic function (total bilirubin ≤ ULN and AST ≤ ULN) following oral administration of a single 40 mg dose of SCEMBLIX. The exposure changes are not considered clinically meaningful.

Drug Interaction Studies

Clinical Studies and Model-Informed Approaches

Drugs That Affect Asciminib Plasma Concentration

Strong CYP3A Inhibitors: The asciminib AUC_inf and C_max increased by 36% and 19%, respectively, following coadministration of a single SCEMBLIX dose of 40 mg with a strong CYP3A4 inhibitor (clarithromycin). No clinically significant differences in the pharmacokinetics of asciminib were observed when coadministered with itraconazole, which is also a strong CYP3A4 inhibitor.

Strong CYP3A Inducers: Concomitant use of strong CYP3A inducers with SCEMBLIX has not been fully characterized.

Itraconazole Oral Solution: Coadministration of multiple doses of itraconazole oral solution containing hydroxypropyl-β-cyclodextrin with a single SCEMBLIX dose of 40 mg decreased asciminib AUC_inf and C_max by 40% and 50%, respectively. Concomitant use of oral products containing hydroxypropyl-β-cyclodextrin with SCEMBLIX other than itraconazole oral solution has not been fully characterized.

Imatinib: The asciminib AUC_inf and C_max increase by 108% and 59%, respectively following coadministration of a single SCEMBLIX dose of 40 mg with imatinib (an inhibitor of BCRP, CYP3A4, UGT2B17, and UGT1A3/4). The exposure changes are not considered clinically meaningful. Concomitant use of imatinib with SCEMBLIX at 200 mg twice daily has not been fully characterized.

Other Drugs: No clinically significant differences in the pharmacokinetics of asciminib were observed when coadministered with rabeprazole (acid-reducing agent) and quinidine (P-gp inhibitor).

Drugs That are Affected by Asciminib

CYP3A4 Substrates: The midazolam AUC_inf and C_max increased by 28% and 11%, respectively, following coadministration of a CYP3A4 substrate (midazolam) with SCEMBLIX 40 mg twice daily. The midazolam AUC_inf and C_max increased by 24% and 17%, respectively, following coadministration with SCEMBLIX at 80 mg once daily and 88% and 58%, respectively, at 200 mg twice daily.

CYP2C9 Substrates: The S-warfarin AUC_inf and C_max increased by 41% and 8%, respectively, following coadministration of CYP2C9 substrate (warfarin) with SCEMBLIX at 40 mg twice daily. The S-warfarin AUC_inf and C_max increased by 52% and 4%, respectively, following coadministration with SCEMBLIX at 80 mg once daily and 314% and 7%, respectively, at 200 mg twice daily.

CYP2C8 Substrates: The repaglinide (substrate of CYP2C8, CYP3A4, and OATP1B) AUC_inf and C_max increased by 8% and 14%, respectively, following coadministration of repaglinide with SCEMBLIX 40 mg twice daily. The repaglinide AUC_inf and C_max increased by 12% and 8%, respectively, following coadministration with SCEMBLIX at 80 mg once daily and 42% and 25%, respectively, at 200 mg twice daily. The rosiglitazone (substrate of CYP2C8 and CYP2C9) AUC_inf and C_max increased by 20% and 3%, respectively, following coadministration of rosiglitazone with SCEMBLIX 40 mg twice daily. The rosiglitazone AUC_inf and C_max increased by 24% and 2%, respectively, following coadministration with SCEMBLIX at 80 mg once daily and 66% and 8%, respectively, at 200 mg twice daily.

P-gp Substrates: Coadministration of SCEMBLIX with a drug that is a substrate of P-gp may result in a clinically relevant increase in the plasma concentrations of P-gp substrates, where minimal concentration changes may lead to serious toxicities.

In Vitro Studies

CYP450 and UGT Enzymes

Asciminib may reversibly inhibit UGT1A1 at plasma concentrations reached at a total daily dose of 80 mg and 200 mg twice daily. In addition, asciminib may reversibly inhibit CYP2C19 at concentrations reached at 200 mg twice daily dose.

Transporter Systems

Asciminib is a substrate of BCRP and P-gp. Asciminib inhibits BCRP, P-gp, OATP1B1, OATP1B3, and OCT1. Asciminib may increase the exposure of OATP1B or BCRP substrates in a dose dependent manner.

13nonclinical Toxicology

13.1Carcinogenesis, Mutagenesis, Impairment of Fertility

In a 2-year carcinogenicity study, rats were administered oral doses of asciminib at 20, 66, and 200 mg/kg/day in males and 10, 30, and 66 mg/kg/day in females. Asciminib induced a statistically significant increase in the incidence of benign Sertoli cell tumors in the ovaries of high-dose females. The exposures to asciminib (AUC) in female rats at 66 mg/kg/day were approximately 8-fold or 6-fold higher than the exposure (AUC) achieved in patients at the dose of 40 mg twice daily or 80 mg once daily, respectively, and equivalent to those achieved in patients at the dose of 200 mg twice daily. The clinical relevance of these findings is currently unknown.

Asciminib was not genotoxic in an in vitro bacterial mutagenicity (Ames) assay, an in vitro micronucleus assay in human peripheral blood lymphocytes (HPBL), or an in vivo rat peripheral blood reticulocyte micronucleus assay.

In a combined male and female fertility and early embryonic development study in rats, animals were administered asciminib doses of 10, 50, or 200 mg/kg/day orally. Male animals were dosed once daily for at least 28 days prior to mating, during the 2-week mating period, and until terminal necropsy (Days 63-67). Female animals were dosed once daily for the 2-week premating period, during the 2-week mating period, and through gestation day (GD) 6. Decreased sperm count and motility were observed at 200 mg/kg/day. While there were no effects on fertility indices or conception rates, a decreased mean number of live embryos was observed at 200 mg/kg/day and was attributed to a lower number of implantations and an increased number of early resorptions. Increased early resorptions were also observed in the embryo-fetal development study in rabbits [see Use in Specific Populations (8.1)].

At the dose of 200 mg/kg, the AUC exposures were approximately 19-fold, 13-fold, or 2-fold higher than those achieved in patients at the 40 mg twice daily, 80 mg once daily, or 200 mg twice daily doses, respectively.

14clinical Studies

14.1Newly Diagnosed Ph+ CML-CP

The efficacy of SCEMBLIX in the treatment of patients with newly diagnosed Ph+ CML in chronic phase (Ph+ CML-CP) was evaluated in the multi-center, randomized, active-controlled, and open-label study ASC4FIRST (NCT04971226).

In this study, a total of 405 patients were randomized in a 1:1 ratio to receive either SCEMBLIX or investigator selected tyrosine kinase inhibitors (IS-TKIs). Prior to randomization, the investigator selected the TKI (imatinib, nilotinib, dasatinib, or bosutinib) to be used in the event of randomization to the comparator arm, based on patient characteristics and comorbidities. Patients were stratified according to EUTOS long-term survival (ELTS) risk group (low, intermediate, high), and pre-randomization selection of TKI (imatinib or other TKIs stratum composed of nilotinib, dasatinib, and bosutinib). Patients received either SCEMBLIX or IS-TKIs, and continued treatment until unacceptable toxicity or treatment failure occurred.

Patients were 37% female and 63% male with median age 51 years (range, 18 to 86 years). Of the 405 patients, 24% were 65 years or older, while 6% were 75 years or older. Patients were White (54%), Asian (44%), Black or African American (1%), and 1% unknown.

Of the 405 patients, 200 received SCEMBLIX, while 201 received IS-TKIs. Of the 201 patients receiving IS-TKIs, 99 received imatinib, 49 received nilotinib, 42 received dasatinib, and 11 received bosutinib. Four patients did not receive any treatment.

The median duration of treatment was 70 weeks (range, 1 to 108 weeks) for patients receiving SCEMBLIX, and 64 weeks (range, 1 to 103 weeks) for patients receiving IS-TKIs. By 48 weeks, 90% of patients on SCEMBLIX, and 81% of patients on IS-TKIs were still receiving treatment.

The main efficacy outcome was major molecular response rate (MMR) at 48 weeks. Efficacy was established based on SCEMBLIX compared to IS-TKIs and SCEMBLIX compared to IS-TKIs within the imatinib stratum. The main efficacy outcomes from ASC4FIRST are summarized in Table 10.

14.2Ph+ CML-CP, Previously Treated with Two or More TKIs

The efficacy of SCEMBLIX in the treatment of patients with Ph+ CML-CP, previously treated with two or more TKIs was evaluated in the multi-center, randomized, active-controlled, and open-label study ASCEMBL (NCT03106779).

In this study, a total of 233 patients were randomized in a 2:1 ratio and stratified according to major cytogenetic response (MCyR) status to receive either SCEMBLIX 40 mg twice daily (N = 157) or bosutinib 500 mg once daily (N = 76). Patients continued treatment until unacceptable toxicity or treatment failure occurred.

Patients were 52% female and 48% male with a median age of 52 years (range, 19 to 83 years). Of the 233 patients, 19% were 65 years or older, while 2.6% were 75 years or older. Patients were White (75%), Asian (14%), and Black or African American (4.3%). Of the 233 patients, 81% and 18% had Eastern Cooperative Oncology Group (ECOG) performance status 0 or 1, respectively. Patients who had previously received 2, 3, 4, or 5 or more prior lines of TKIs were 48%, 31%, 15%, and 6%, respectively. The median duration of treatment was 103 weeks (range, 0.1 to 201 weeks) for patients receiving SCEMBLIX and 31 weeks (range, 1 to 188 weeks) for patients receiving bosutinib.

The main efficacy outcomes from ASCEMBL are summarized in Table 11.

With a median duration of follow-up of 28 months (range, 1 day to 45 months), the median duration of response for patients treated with SCEMBLIX had not yet been reached.

14.3Ph+ CML-CP with the T315I Mutation

The efficacy of SCEMBLIX in the treatment of patients with Ph+ CML-CP with the T315I mutation was evaluated in a multi-center open-label study CABL001X2101 (NCT02081378). Testing for T315I mutation utilized a qualitative p210 BCR::ABL1 mutation test on peripheral blood using Sanger Sequencing.

Efficacy was based on 45 patients with Ph+ CML-CP with the T315I mutation who received SCEMBLIX at a dose of 200 mg twice daily. Patients continued treatment until unacceptable toxicity or treatment failure occurred.

Of the 45 patients, 80% were male and 20% female; 31% were 65 years or older, while 9% were 75 years or older with a median age of 54 years (range, 26 to 86 years). The patients were White (47%), Asian (27%), and Black or African American (2.2%), and 24% were unreported or unknown. Seventy-three percent and 27% of patients had ECOG performance status 0 and 1, respectively. Patients who had previously received 1, 2, 3, 4, and 5 or more TKIs were 18%, 31%, 36%, 13%, and 2.2%, respectively. MMR was achieved by 24 weeks in 42% (19/45, 95% CI: 28% to 58%) of the 45 patients treated with SCEMBLIX. MMR was achieved by 96 weeks in 49% (22/45, 95% CI: 34% to 64%) of the 45 patients treated with SCEMBLIX. The median duration of treatment was 108 weeks (range, 2 to 215 weeks).
