6.1Clinical Trials 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 rates in the clinical trials of another drug and may not reflect the rates observed in practice.

Data were evaluated from 1613 patients in a large phase 3 study who received at least one dose of lenalidomide capsules with low dose dexamethasone (Rd) given for 2 different durations of time (i.e., until progressive disease [Arm Rd Continuous; N = 532] or for up to eighteen 28-day cycles [72 weeks, Arm Rd18; N = 540] or who received melphalan, prednisone and thalidomide (Arm MPT; N = 541) for a maximum of twelve 42-day cycles (72 weeks). The median treatment duration in the Rd Continuous arm was 80.2 weeks (range 0.7 to 246.7) or 18.4 months (range 0.16 to 56.7).

In general, the most frequently reported adverse reactions were comparable in Arm Rd Continuous and Arm Rd18, and included diarrhea, anemia, constipation, peripheral edema, neutropenia, fatigue, back pain, nausea, asthenia, and insomnia. The most frequently reported Grade 3 or 4 reactions included neutropenia, anemia, thrombocytopenia, pneumonia, asthenia, fatigue, back pain, hypokalemia, rash, cataract, lymphopenia, dyspnea, DVT, hyperglycemia, and leukopenia. The highest frequency of infections occurred in Arm Rd Continuous (75%) compared to Arm MPT (56%). There were more grade 3 and 4 and serious adverse reactions of infection in Arm Rd Continuous than either Arm MPT or Rd18.

In the Rd Continuous arm, the most common adverse reactions leading to dose interruption of lenalidomide capsules were infection events (28.8%); overall, the median time to the first dose interruption of lenalidomide capsules was 7 weeks. The most common adverse reactions leading to dose reduction of lenalidomide capsules in the Rd Continuous arm were hematologic events (10.7%); overall, the median time to the first dose reduction of lenalidomide capsules was 16 weeks. In the Rd Continuous arm, the most common adverse reactions leading to discontinuation of lenalidomide capsules were infection events (3.4%).

In both Rd arms, the frequencies of onset of adverse reactions were generally highest in the first 6 months of treatment and then the frequencies decreased over time or remained stable throughout treatment, except for cataracts. The frequency of onset of cataracts increased over time with 0.7% during the first 6 months and up to 9.6% by the 2nd year of treatment with Rd Continuous.

Table 4 summarizes the adverse reactions reported for the Rd Continuous, Rd18, and MPT treatment arms.

Data were evaluated from 1018 patients in two randomized trials who received at least one dose of lenalidomide capsules 10 mg daily as maintenance therapy after auto-HSCT until progressive disease or unacceptable toxicity. The mean treatment duration for lenalidomide capsule treatment was 30.3 months for Maintenance Study 1 and 24.0 months for Maintenance Study 2 (overall range across both studies from 0.1 to 108 months). As of the cut-off date of 1 Mar 2015, 48 patients (21%) in the Maintenance Study 1 lenalidomide capsules arm were still on treatment and none of the patients in the Maintenance Study 2 lenalidomide capsules arm were still on treatment at the same cut-off date.

The adverse reactions uled from Maintenance Study 1 included events reported post-transplant (completion of high-dose melphalan/auto-HSCT), and the maintenance treatment period. In Maintenance Study 2, the adverse reactions were from the maintenance treatment period only. In general, the most frequently reported adverse reactions (more than 20% in the lenalidomide capsules arm) across both studies were neutropenia, thrombocytopenia, leukopenia, anemia, upper respiratory tract infection, bronchitis, nasopharyngitis, cough, gastroenteritis, diarrhea, rash, fatigue, asthenia, muscle spasm and pyrexia. The most frequently reported Grade 3 or 4 reactions (more than 20% in the lenalidomide capsules arm) included neutropenia, thrombocytopenia, and leukopenia. The serious adverse reactions lung infection and neutropenia (more than 4.5%) occurred in the lenalidomide capsules arm.

For lenalidomide capsules, the most common adverse reactions leading to dose interruption were hematologic events (29.7%, data available in Maintenance Study 2 only). The most common adverse reaction leading to dose reduction of lenalidomide capsules were hematologic events (17.7%, data available in Maintenance Study 2 only). The most common adverse reactions leading to discontinuation of lenalidomide capsules were thrombocytopenia (2.7%) in Maintenance Study 1 and neutropenia (2.4%) in Maintenance Study 2.

The frequencies of onset of adverse reactions were generally highest in the first 6 months of treatment and then the frequencies decreased over time or remained stable throughout treatment.

Table 5 summarizes the adverse reactions reported for the lenalidomide capsules and placebo maintenance treatment arms.

Data were evaluated from 703 patients in two studies who received at least one dose of lenalidomide capsules/dexamethasone (353 patients) or placebo/dexamethasone (350 patients).

In the lenalidomide capsules/dexamethasone treatment group, 269 patients (76%) had at least one dose interruption with or without a dose reduction of lenalidomide capsules compared to 199 patients (57%) in the placebo/dexamethasone treatment group. Of these patients who had one dose interruption with or without a dose reduction, 50% in the lenalidomide capsules/dexamethasone treatment group had at least one additional dose interruption with or without a dose reduction compared to 21% in the placebo/dexamethasone treatment group. Most adverse reactions and Grade 3/4 adverse reactions were more frequent in patients who received the combination of lenalidomide capsules/dexamethasone compared to placebo/dexamethasone.

Tables 6, 7, and 8 summarize the adverse reactions reported for lenalidomide capsules/dexamethasone and placebo/dexamethasone groups.

Median duration of exposure among patients treated with lenalidomide capsules/dexamethasone was 44 weeks while median duration of exposure among patients treated with placebo/dexamethasone was 23 weeks. This should be taken into consideration when comparing frequency of adverse reactions between two treatment groups lenalidomide capsules/dexamethasone vs placebo/dexamethasone.

[See Boxed Warning, Warnings and Precautions (5.4).]

VTE and ATE are increased in patients treated with lenalidomide capsules.

Deep vein thrombosis (DVT) was reported as a serious (7.4%) or severe (8.2%) adverse drug reaction at a higher rate in the lenalidomide capsules/dexamethasone group compared to 3.1% and 3.4% in the placebo/dexamethasone group, respectively in the 2 studies in patients with at least 1 prior therapy with discontinuations due to DVT adverse reactions reported at comparable rates between groups. In the NDMM study, DVT was reported as an adverse reaction (all grades: 10.3%, 7.2%, 4.1%), as a serious adverse reaction (3.6%, 2.0%, 1.7%), and as a Grade 3/4 adverse reaction (5.6%, 3.7%, 2.8%) in the Rd Continuous, Rd18, and MPT Arms, respectively. Discontinuations and dose reductions due to DVT adverse reactions were reported at comparable rates between the Rd Continuous and Rd18 Arms (both < 1%). Interruption of lenalidomide capsule treatment due to DVT adverse reactions was reported at comparable rates between the Rd Continuous (2.3%) and Rd18 (1.5%) arms. Pulmonary embolism (PE) was reported as a serious adverse drug reaction (3.7%) or Grade 3/4 (4.0%) at a higher rate in the lenalidomide capsules/dexamethasone group compared to 0.9% (serious or grade 3/4) in the placebo/dexamethasone group in the 2 studies in patients with, at least 1 prior therapy, with discontinuations due to PE adverse reactions reported at comparable rates between groups. In the NDMM study, the frequency of adverse reactions of PE was similar between the Rd Continuous, Rd18, and MPT Arms for adverse reactions (all grades: 3.9%, 3.3%, and 4.3%, respectively), serious adverse reactions (3.8%, 2.8%, and 3.7%, respectively), and grade 3/4 adverse reactions (3.8%, 3.0%, and 3.7%, respectively).

Myocardial infarction was reported as a serious (1.7%) or severe (1.7%) adverse drug reaction at a higher rate in the lenalidomide capsules/dexamethasone group compared to 0.6% and 0.6% respectively in the placebo/dexamethasone group. Discontinuation due to MI (including acute) adverse reactions was 0.8% in lenalidomide capsules/dexamethasone group and none in the placebo/dexamethasone group. In the NDMM study, myocardial infarction (including acute) was reported as an adverse reaction (all grades: 2.4%, 0.6%, and 1.1%), as a serious adverse reaction, (2.3%, 0.6%, and 1.1%), or as a severe adverse reaction (1.9%, 0.6%, and 0.9%) in the Rd Continuous, Rd18, and MPT Arms, respectively.

Stroke (CVA) was reported as a serious (2.3%) or severe (2.0%) adverse drug reaction in the lenalidomide capsules/dexamethasone group compared to 0.9% and 0.9% respectively in the placebo/dexamethasone group. Discontinuation due to stroke (CVA) was 1.4% in lenalidomide capsules/dexamethasone group and 0.3% in the placebo/dexamethasone group. In the NDMM study, CVA was reported as an adverse reaction (all grades: 0.8%, 0.6%, and 0.6%), as a serious adverse reaction (0.8%, 0.6%, and 0.6%), or as a severe adverse reaction (0.6%, 0.6%, 0.2%) in the Rd Continuous, Rd18, and MPT arms respectively.

In these 2 studies, the following adverse drug reactions (ADRs) not described above that occurred at ≥ 1% rate and of at least twice of the placebo percentage rate were reported:

Blood and Lymphatic System Disorders: pancytopenia, autoimmune hemolytic anemia

Cardiac Disorders: bradycardia, myocardial infarction, angina pectoris

Endocrine Disorders: hirsutism

Eye Disorders: blindness, ocular hypertension

Gastrointestinal Disorders: gastrointestinal hemorrhage, glossodynia

A total of 148 patients received at least 1 dose of 10 mg lenalidomide capsules in the del 5q MDS clinical study. At least one adverse reaction was reported in all of the 148 patients who were treated with the 10 mg starting dose of lenalidomide capsules. The most frequently reported adverse reactions were related to blood and lymphatic system disorders, skin and subcutaneous tissue disorders, gastrointestinal disorders, and general disorders and administrative site conditions.

Thrombocytopenia (61.5%; 91/148) and neutropenia (58.8%; 87/148) were the most frequently reported adverse reactions. The next most common adverse reactions observed were diarrhea (48.6%; 72/148), pruritus (41.9%; 62/148), rash (35.8%; 53/148) and fatigue (31.1%; 46/148). Table 9 summarizes the adverse reactions that were reported in ≥ 5% of the lenalidomide capsule-treated patients in the del 5q MDS clinical study. Table 10 summarizes the most frequently observed Grade 3 and Grade 4 adverse reactions regardless of relationship to treatment with lenalidomide capsules. In the single-arm studies conducted, it is often not possible to distinguish adverse reactions that are drug-related and those that reflect the patient’s underlying disease.

In the AUGMENT trial, patients received lenalidomide capsules 20 mg daily by mouth on days 1-21 of each 28-day cycle with rituximab 375 mg/m² weekly (days 1, 8, 15 and 22 in cycle 1) then on day 1 of cycles 2-5 (n = 176) or placebo with rituximab 375 mg/m² weekly (days 1, 8, 15 and 22 in cycle 1) then on day 1 of cycles 2-5 (n = 180) for up to 12 cycles. In the MAGNIFY trial, patients received lenalidomide capsules 20 mg by mouth daily, days 1-21 of each 28-day cycle with rituximab 375 mg/m² weekly (days 1, 8, 15 and 22 in cycle 1) then on day 1 of cycles 3, 5, 7, 9 and 11 in the induction phase of the trial (n = 222). In the AUGMENT trial, 88.1% of patients completed at least 6 cycles of lenalidomide capsules/rituximab, and 71% of patients completed 12 cycles. In the ongoing MAGNIFY trial as of May 1, 2017, 62.2% of patients completed at least 6 cycles of lenalidomide capsules/rituximab, and 30.6% of patients completed 12 cycles.

Across both clinical trials (AUGMENT and MAGNIFY), patients had a median age of 64.5 years (26 to 91); 49% were male; and 81% were White.

Fatal adverse reactions occurred in 6 patients (1.5%) receiving lenalidomide capsules/rituximab. Fatal adverse reactions (1 each) included cardio-respiratory arrest, arrhythmia, cardiopulmonary failure, multiple organ dysfunction syndrome, sepsis, and acute kidney injury. Serious adverse reactions occurred in 26% of patients receiving lenalidomide capsules/rituximab in AUGMENT and 29% in MAGNIFY. The most frequent serious adverse reaction that occurred in ≥ 2.5% of patients in the lenalidomide capsules/rituximab arm was febrile neutropenia (3%). Permanent discontinuation of lenalidomide capsules or rituximab due to an adverse reaction occurred in 14.6% of patients in the lenalidomide capsules/rituximab arm. The most common adverse reaction (in at least 1%) requiring permanent discontinuation of lenalidomide capsules or rituximab was neutropenia (4.8%).

The most common adverse reactions occurring in at least 20% of subjects were; neutropenia (48%), fatigue (37%), diarrhea (32%), constipation (27%), nausea (21%), and cough (20%).

6.2Postmarketing Experience

The following adverse drug reactions have been identified from the worldwide postmarketing experience with lenalidomide capsules. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure [see Warnings and Precautions Section (5.8, 5.9, 5.10, 5.11, and 5.13)].

Endocrine Disorders:  Hypothyroidism, hyperthyroidism

Hepatobiliary Disorders:  Hepatic failure (including fatality), toxic hepatitis, cytolytic hepatitis, cholestatic hepatitis, mixed cytolytic/cholestatic hepatitis, transient abnormal liver laboratory tests

Immune System Disorders:  Angioedema, anaphylaxis, acute graft-versus-host disease (following allogeneic hematopoietic transplant), solid organ transplant rejection

Infections and Infestations:  Viral reactivation (such as hepatitis B virus and herpes zoster), progressive multifocal leukoencephalopathy (PML)

Neoplasms Benign, Malignant and Unspecified (Including Cysts and Polyps):  Tumor lysis syndrome, tumor flare reaction

Respiratory, Thoracic and Mediastinal Disorders:  Pneumonitis

Skin and Subcutaneous Tissue Disorders:  Stevens-Johnson Syndrome, toxic epidermal necrolysis, drug reaction with eosinophilia and systemic symptoms (DRESS)
