WARNING: EMBRYO-FETAL TOXICITY, HEMATOLOGIC TOXICITY, and VENOUS and ARTERIAL THROMBOEMBOLISM WARNING: EMBRYO-FETAL TOXICITY, HEMATOLOGIC TOXICITY, and VENOUS and ARTERIAL THROMBOEMBOLISM Embryo-Fetal Toxicity Do not use lenalidomide capsules during pregnancy. Lenalidomide, a thalidomide analogue, caused limb abnormalities in a developmental monkey study. Thalidomide is a known human teratogen that causes severe life-threatening human birth defects. If lenalidomide is used during pregnancy, it may cause birth defects or embryo-fetal death. In females of reproductive potential, obtain 2 negative pregnancy tests before starting lenalidomide capsules treatment. Females of reproductive potential must use 2 forms of contraception or continuously abstain from heterosexual sex during and for 4 weeks after lenalidomide capsules treatment [ see Warnings and Precautions ( 5.1 ), and Medication Guide ( 17 ) ] . To avoid embryo-fetal exposure to lenalidomide, lenalidomide capsules are only available through a restricted distribution program, the Lenalidomide REMS program ( 5.2 ). Information about the Lenalidomide REMS program is available at www.lenalidomiderems.com or by calling the manufacturer’s toll-free number 1-866-604-3268. Hematologic Toxicity (Neutropenia and Thrombocytopenia) Lenalidomide capsules can cause significant neutropenia and thrombocytopenia. Eighty percent of patients with del 5q myelodysplastic syndromes had to have a dose delay/reduction during the major study. Thirty-four percent of patients had to have a second dose delay/reduction. Grade 3 or 4 hematologic toxicity was seen in 80% of patients enrolled in the study. Patients on therapy for del 5q myelodysplastic syndromes should have their complete blood counts monitored weekly for the first 8 weeks of therapy and at least monthly thereafter. Patients may require dose interruption and/or reduction. Patients may require use of blood product support and/or growth factors [see Dosage and Administration ( 2.2 )] . Venous and Arterial Thromboembolism Lenalidomide capsule has demonstrated a significantly increased risk of deep vein thrombosis (DVT) and pulmonary embolism (PE), as well as risk of myocardial infarction and stroke in patients with multiple myeloma who were treated with lenalidomide capsules and dexamethasone therapy. Monitor for and advise patients about signs and symptoms of thromboembolism. Advise patients to seek immediate medical care if they develop symptoms such as shortness of breath, chest pain, or arm or leg swelling. Thromboprophylaxis is recommended and the choice of regimen should be based on an assessment of the patient’s underlying risks [see Warnings and Precautions ( 5.4 )] . WARNING: EMBRYO-FETAL TOXICITY, HEMATOLOGIC TOXICITY, and VENOUS and ARTERIAL THROMBOEMBOLISM See full prescribing information for complete boxed warning. EMBRYO-FETAL TOXICITY Lenalidomide, a thalidomide analogue, caused limb abnormalities in a developmental monkey study similar to birth defects caused by thalidomide in humans. If lenalidomide is used during pregnancy, it may cause birth defects or embryo-fetal death. Pregnancy must be excluded before start of treatment. Prevent pregnancy during treatment by the use of two reliable methods of contraception ( 5.1 ). Lenalidomide capsules are available only through a restricted distribution program, called the Lenalidomide REMS program ( 5.2 , 17 ). HEMATOLOGIC TOXICITY . Lenalidomide capsules can cause significant neutropenia and thrombocytopenia ( 5.3 ). VENOUS AND ARTERIAL THROMBOEMBOLISM Significantly increased risk of deep vein thrombosis (DVT) and pulmonary embolism (PE), as well as risk of myocardial infarction and stroke in patients with multiple myeloma receiving lenalidomide capsules with dexamethasone. Anti-thrombotic prophylaxis is recommended ( 5.4 ). 5 WARNINGS AND PRECAUTIONS Increased Mortality: serious and fatal cardiac adverse reactions occurred in patients with CLL treated with lenalidomide capsules …

4 CONTRAINDICATIONS Pregnancy (Boxed Warning, 4.1 , 5.1 , 8.1 ). Demonstrated severe hypersensitivity to lenalidomide ( 4.2 , 5.9 , 5.15 ). 4.1 Pregnancy Lenalidomide can cause fetal harm when administered to a pregnant female. Limb abnormalities were seen in the offspring of monkeys that were dosed with lenalidomide during organogenesis. This effect was seen at all doses tested. Due to the results of this developmental monkey study, and lenalidomide’s structural similarities to thalidomide, a known human teratogen, lenalidomide is contraindicated in females who are pregnant [ see Boxed Warning ] . If this drug is used during pregnancy or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential risk to a fetus [see Warnings and Precautions ( 5.1 , 5.2 ), Use in Special Populations ( 8.1 , 8.3) ] . 4.2 Severe Hypersensitivity Reactions Lenalidomide capsules are contraindicated in patients who have demonstrated severe hypersensitivity (e.g., angioedema, Stevens-Johnson syndrome, toxic epidermal necrolysis) to lenalidomide [see Warnings and Precautions ( 5.9 , 5.15 )] .

7 DRUG INTERACTIONS Digoxin: Monitor digoxin plasma levels periodically due to increased C max and AUC with concomitant lenalidomide capsules therapy ( 7.1 ). Concomitant use of erythropoietin stimulating agents or estrogen containing therapies with lenalidomide capsules may increase the risk of thrombosis ( 7.2 ). 7.1 Digoxin When digoxin was co-administered with multiple doses of lenalidomide (10 mg/day) the digoxin C max and AUC inf were increased by 14%. Periodically monitor digoxin plasma levels, in accordance with clinical judgment and based on standard clinical practice in patients receiving this medication, during administration of lenalidomide capsules. 7.2 Concomitant Therapies That May Increase the Risk of Thrombosis Erythropoietic agents, or other agents that may increase the risk of thrombosis, such as estrogen containing therapies, should be used with caution after making a benefit-risk assessment in patients receiving lenalidomide capsules [see Warnings and Precautions ( 5.4 )] . 7.3 Warfarin Co-administration of multiple doses of lenalidomide (10 mg/day) with a single dose of warfarin (25 mg) had no effect on the pharmacokinetics of lenalidomide or R- and S-warfarin. Expected changes in laboratory assessments of PT and INR were observed after warfarin administration, but these changes were not affected by concomitant lenalidomide administration. It is not known whether there is an interaction between dexamethasone and warfarin. Close monitoring of PT and INR is recommended in patients with MM taking concomitant warfarin.

4.1 Pregnancy Lenalidomide can cause fetal harm when administered to a pregnant female. Limb abnormalities were seen in the offspring of monkeys that were dosed with lenalidomide during organogenesis. This effect was seen at all doses tested. Due to the results of this developmental monkey study, and lenalidomide’s structural similarities to thalidomide, a known human teratogen, lenalidomide is contraindicated in females who are pregnant [ see Boxed Warning ] . If this drug is used during pregnancy or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential risk to a fetus [see Warnings and Precautions ( 5.1 , 5.2 ), Use in Special Populations ( 8.1 , 8.3) ] . 8.1 Pregnancy Pregnancy Exposure Registry There is a pregnancy exposure registry that monitors pregnancy outcomes in females exposed to lenalidomide during pregnancy as well as female partners of male patients who are exposed to lenalidomide. This registry is also used to understand the root cause for the pregnancy. Report any suspected fetal exposure to lenalidomide capsules to the FDA via the MedWatch program at 1-800-FDA-1088 and also to Cipla Ltd. at 1-866-604-3268. Risk Summary Based on the mechanism of action [ see Clinical Pharmacology ( 12.1 )] and findings from animal studies [see Data], lenalidomide can cause embryo-fetal harm when administered to a pregnant female and is contraindicated during pregnancy [ see Boxed Warning , Contraindications ( 4.1 ), and Use in Specific Populations ( 5.1 )] . Lenalidomide is a thalidomide analogue. Thalidomide is a human teratogen, inducing a high frequency of severe and life-threatening birth defects such as amelia (absence of limbs), phocomelia (short limbs), hypoplasticity of the bones, absence of bones, external ear abnormalities (including anotia, micropinna, small or absent external auditory canals), facial palsy, eye abnormalities (anophthalmos, microphthalmos), and congenital heart defects. Alimentary tract, urinary tract, and genital malformations have also been documented and mortality at or shortly after birth has been reported in about 40% of infants. Lenalidomide caused thalidomide-type limb defects in monkey offspring. Lenalidomide crossed the placenta after administration to pregnant rabbits and pregnant rats [see Data] . If this drug is used during pregnancy, or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential risk to a fetus. If pregnancy does occur during treatment, immediately discontinue the drug. Under these conditions, refer patient to an obstetrician/gynecologist experienced in reproductive toxicity for further evaluation and counseling. Report any suspected fetal exposure to lenalidomide capsules to the FDA via the MedWatch program at 1-800-FDA-1088 and also to Cipla Ltd. at 1-866-604-3268. The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. The estimated background risk in the U.S. general population of major birth defects is 2%-4% and of miscarriage is 15%-20% of clinically recognized pregnancies. Data Animal data In an embryo-fetal developmental toxicity study in monkeys, teratogenicity, including thalidomide-like limb defects, occurred in offspring when pregnant monkeys received oral lenalidomide during organogenesis. Exposure (AUC) in monkeys at the lowest dose was 0.17 times the human exposure at the maximum recommended human dose (MRHD) of 25 mg. Similar studies in pregnant rabbits and rats at 20 times and 200 times the MRHD respectively, produced embryo lethality in rabbits and no adverse reproductive effects in rats. In a pre- and post-natal development study in rats, animals received lenalidomide from organogenesis through lactation. The study revealed a few adverse effects on the offspring of female rats treated with lenalidomide at doses up to 50…

Newly Diagnosed MM – Lenalidomide Capsule Combination Therapy: Data were evaluated from 1613 patients in a large phase 3 study who received at least one dose of lenalidomide capsule 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 cap…
