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 capsules 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 )] .
Warnings and precautions
Increased Mortality: serious and fatal cardiac adverse reactions occurred in patients with CLL treated with lenalidomide capsules ( 5.5 ). Second Primary Malignancies (SPM): Higher incidences of SPM were observed in controlled trials of patients with MM receiving lenalidomide capsules ( 5.6 ). Increased Mortality: Observed in patients with MM when pembrolizumab was added to dexamethasone and a thalidomide analogue ( 5.7 ). Hepatotoxicity: Hepatic failure including fatalities; monitor liver function. Stop lenalidomide capsules and evaluate if hepatotoxicity is suspected ( 5.8 ). Severe Cutaneous Reactions: Discontinue lenalidomide for severe reactions ( 5.9 ). Tumor lysis syndrome (TLS) including fatalities: Monitor patients at risk of TLS (i.e., those with high tumor burden) and take appropriate precautions ( 5.10 ). Tumor flare reaction: Serious tumor flare reactions, including fatal reactions, have occurred during investigational use of lenalidomide capsules for chronic lymphocytic leukemia and lymphoma ( 5.11 ). Impaired Stem Cell mobilization: A decrease in the number of CD34+ cells collected after treatment (> 4 cycles) with lenalidomide has been reported. Consider early referral to transplant center ( 5.12 ). Early mortality in MCL: Higher rate of early deaths have occurred in patients with MCL ( 5.14 ). Hypersensitivity: Monitor patients for potential hypersensitivity. Discontinue lenalidomide for angioedema and anaphylaxis ( 5.15 ). 5.1 Embryo-Fetal Toxicity Lenalidomide is a thalidomide analogue and is contraindicated for use during pregnancy. Thalidomide is a known human teratogen that causes life-threatening human birth defects or embryo-fetal death [see Use in Specific Populations ( 8.1 )] . An embryo-fetal development study in monkeys indicates that lenalidomide produced malformations in the offspring of female monkeys who received the drug during pregnancy, similar to birth defects observed in humans following exposure to thalidomide during pregnancy. Lenalidomide capsules are only available through the Lenalidomide REMS program [see Warnings and Precautions ( 5.2 )] . Females of Reproductive Potential Females of reproductive potential must avoid pregnancy for at least 4 weeks before beginning lenalidomide capsules therapy, during therapy, during dose interruptions and for at least 4 weeks after completing therapy. Females must commit either to abstain continuously from heterosexual sexual intercourse or to use two methods of reliable birth control, beginning 4 weeks prior to initiating treatment with lenalidomide capsules, during therapy, during dose interruptions and continuing for 4 weeks following discontinuation of lenalidomide therapy. Two negative pregnancy tests must be obtained prior to initiating therapy. The first test should be performed within 10 to 14 days and the second test within 24 hours prior to prescribing lenalidomide therapy and then weekly during the first month, then monthly thereafter in females with regular menstrual cycles or every 2 weeks in females with irregular menstrual cycles [see Use in Specific Populations ( 8.3 )] . Males Lenalidomide is present in the semen of patients receiving the drug. Therefore, males must always use a latex or synthetic condom during any sexual contact with females of reproductive potential while taking lenalidomide capsules and for up to 4 weeks after discontinuing lenalidomide capsules, even if they have undergone a successful vasectomy. Male patients taking lenalidomide capsules must not donate sperm and for up to 4 weeks after discontinuing lenalidomide capsules [see Use in Specific Populations ( 8.3 )] . Blood Donation Patients must not donate blood during treatment with lenalidomide capsules and for 4 weeks following discontinuation of the drug because the blood might be given to a pregnant female patient whose fetus must not be exposed to lenalidomide. 5.2 Lenalidomide REMS Program Because of the embryo-fetal risk [see Warnings and Precautions ( 5.1 )] , lenalidomide capsules are available only through a restricted program under a Risk Evaluation and Mitigation Strategy (REMS), the Lenalidomide REMS program. Required components of the Lenalidomide REMS program include the following: Prescribers must be certified with the Lenalidomide REMS program by enrolling and complying with the REMS requirements. Patients must sign a Patient-Physician agreement form and comply with the REMS requirements. In particular, female patients of reproductive potential who are not pregnant must comply with the pregnancy testing and contraception requirements [see Use in Specific Populations ( 8.3 )] and males must comply with contraception requirements [see Use in Specific Populations ( 8.3 )] . Pharmacies must be certified with the Lenalidomide REMS program, must only dispense to patients who are authorized to receive lenalidomide capsules and comply with REMS requirements. Further information about the Lenalidomide REMS program is available at www.lenalidomiderems.com or by telephone at 1-888-423-5436. 5.3 Hematologic Toxicity Lenalidomide capsules can cause significant neutropenia and thrombocytopenia. Monitor patients with neutropenia for signs of infection. Advise patients to observe for bleeding or bruising, especially with use of concomitant medication that may increase risk of bleeding. Patients taking lenalidomide capsules should have their complete blood counts assessed periodically as described below [see Dosage and Administration ( 2.1 , 2.2 , 2.3 )] . Monitor complete blood counts (CBC) in patients taking lenalidomide capsules in combination with dexamethasone or as lenalidomide capsules maintenance therapy for MM every 7 days (weekly) for the first 2 cycles, on Days 1 and 15 of Cycle 3, and every 28 days (4 weeks) thereafter. A dose interruption and/or dose reduction may be required [see Dosage and Administration ( 2.1 )] .
Side effects
The following clinically significant adverse reactions are described in detail in other sections of the prescribing information: Embryo-Fetal Toxicity [see Boxed Warning , Warnings and Precautions ( 5.1 , 5.2 )] Hematologic Toxicity [see Boxed Warning , Warnings and Precautions ( 5.3 )] Venous and Arterial Thromboembolism [see Boxed Warning , Warnings and Precautions ( 5.4 )] Increased Mortality in Patients with CLL [see Warnings and Precautions ( 5.5 )] Second Primary Malignancies [see Warnings and Precautions ( 5.6 )] Increased Mortality in Patients with MM When Pembrolizumab Is Added to a Thalidomide Analogue and Dexamethasone [see Warnings and Precautions ( 5.7 )] Hepatotoxicity [see Warnings and Precautions ( 5.8 )] Severe Cutaneous Reactions [see Warnings and Precautions ( 5.9 )] Tumor Lysis Syndrome [see Warnings and Precautions ( 5.10 )] Tumor Flare Reactions [see Warnings and Precautions ( 5.11 )] Impaired Stem Cell Mobilization [see Warnings and Precautions ( 5.12 )] Thyroid Disorders [see Warnings and Precautions ( 5.13 )] Early Mortality in Patients with MCL [see Warnings and Precautions ( 5.14 )] Hypersensitivity [see Warnings and Precautions ( 5.15 )] MM: Most common adverse reactions (≥20%) include diarrhea, fatigue, anemia, constipation, neutropenia, leukopenia, peripheral edema, insomnia, muscle cramp/spasms, abdominal pain, back pain, nausea, asthenia, pyrexia, upper respiratory tract infection, bronchitis, nasopharyngitis, gastroenteritis, cough, rash, dyspnea, dizziness, decreased appetite, thrombocytopenia, and tremor ( 6.1 ). MDS: Most common adverse reactions (>15%) include thrombocytopenia, neutropenia, diarrhea, pruritus, rash, fatigue, constipation, nausea, nasopharyngitis, arthralgia, pyrexia, back pain, peripheral edema, cough, dizziness, headache, muscle cramp, dyspnea, pharyngitis, and epistaxis ( 6.1 ). Non-Hodgkin’s Lymphoma (NHL: MCL, FL or MZL): Most common adverse reactions (≥15%) included neutropenia, thrombocytopenia, anemia, leukopenia, diarrhea, constipation, nausea, fatigue, pyrexia, cough, upper respiratory tract infection, and rash ( 6.1 ). To report SUSPECTED ADVERSE REACTIONS contact Teva at 1-888-838-2872 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical 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. Newly Diagnosed MM – Lenalidomide Capsules Combination Therapy: Data were evaluated from 1613 patients in a large phase 3 study who received at least one dose of lenalidomide 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 were infection events (28.8%); overall, the median time to the first dose interruption of lenalidomide was 7 weeks. The most common adverse reactions leading to dose reduction of lenalidomide in the Rd Continuous arm were hematologic events (10.7%); overall, the median time to the first dose reduction of lenalidomide was 16 weeks. In the Rd Continuous arm, the most common adverse reactions leading to discontinuation of lenalidomide 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.
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 capsules (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 [see Warnings and Precautions ( 5.4 )] . 7.3 Warfarin Co-administration of multiple doses of lenalidomide capsules (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 capsules 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.
Use in specific populations
Lactation: Advise not to breastfeed ( 8.2 ). 8.1 Pregnancy Pregnancy Exposure Registry There is a pregnancy exposure registry that monitors pregnancy outcomes in females exposed to lenalidomide capsules during pregnancy as well as female partners of male patients who are exposed to lenalidomide capsules. 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 the REMS Call Center at 1‐888‐423‐5436. 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 the REMS Call Center at 1‐888‐423‐5436. 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% to 4% and of miscarriage is 15% to 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 500 mg/kg (approximately 200 times the human dose of 25 mg based on body surface area). The male offspring exhibited slightly delayed sexual maturation and the female offspring had slightly lower body weight gains during gestation when bred to male offspring. As with thalidomide, the rat model may not adequately address the full spectrum of potential human embryo-fetal developmental effects for lenalidomide. Following daily oral administration of lenalidomide from Gestation Day 7 through Gestation Day 20 in pregnant rabbits, fetal plasma lenalidomide concentrations were approximately 20% to 40% of the maternal C max . Following a single oral dose to pregnant rats, lenalidomide was detected in fetal plasma and tissues; concentrations of radioactivity in fetal tissues were generally lower than those in maternal tissues. These data indicated that lenalidomide crossed the placenta. 8.2 Lactation Risk Summary There is no information regarding the presence of lenalidomide in human milk, the effects of lenalidomide capsules on the breastfed child, or the effects of lenalidomide on milk production. Because many drugs are excreted in human milk and because of the potential for adverse reactions in breastfed children from lenalidomide capsules, advise women not to breastfeed during treatment with lenalidomide capsules. 8.3 Females and Males of Reproductive Potential Pregnancy Testing Lenalidomide capsules can cause fetal harm when administered during pregnancy [see Use in Specific Populations ( 8.1 )] . Verify the pregnancy status of females of reproductive potential prior to initiating lenalidomide capsules therapy and during therapy. Advise females of reproductive potential that they must avoid pregnancy 4 weeks before therapy, while taking lenalidomide capsules, during dose interruptions and for at least 4 weeks after completing therapy. Females of reproductive potential must have 2 negative pregnancy tests before initiating lenalidomide capsules. The first test should be performed within 10 to 14 days, and the second test within 24 hours prior to prescribing lenalidomide capsules. Once treatment has started and during dose interruptions, pregnancy testing for females of reproductive potential should occur weekly during the first 4 weeks of use, then pregnancy testing should be repeated every 4 weeks in females with regular menstrual cycles. If menstrual cycles are irregular, the pregnancy testing should occur every 2 weeks. Pregnancy testing and counseling should be performed if a patient misses her period or if there is any abnormality in her menstrual bleeding.

Pediatric use
8.4 Pediatric Use Safety and effectiveness have not been established in pediatric patients.
Geriatric use
8.5 Geriatric Use MM In Combination : Overall, of the 1613 patients in the NDMM study who received study treatment, 94% (1521/1613) were 65 years of age or older, while 35% (561/1613) were over 75 years of age. The percentage of patients over age 75 was similar between study arms (Rd Continuous: 33%; Rd18: 34%; MPT: 33%). Overall, across all treatment arms, the frequency in most of the adverse reaction categories (eg, all adverse reactions, grade 3/4 adverse reactions, serious adverse reactions) was higher in older (> 75 years of age) than in younger (≤ 75 years of age) subjects. Grade 3 or 4 adverse reactions in the General Disorders and Administration Site Conditions body system were consistently reported at a higher frequency (with a difference of at least 5%) in older subjects than in younger subjects across all treatment arms. Grade 3 or 4 adverse reactions in the Infections and Infestations, Cardiac Disorders (including cardiac failure and congestive cardiac failure), Skin and Subcutaneous Tissue Disorders, and Renal and Urinary Disorders (including renal failure) body systems were also reported slightly, but consistently, more frequently (<5% difference), in older subjects than in younger subjects across all treatment arms. For other body systems (e.g., Blood and Lymphatic System Disorders, Infections and Infestations, Cardiac Disorders, Vascular Disorders), there was a less consistent trend for increased frequency of grade 3/4 adverse reactions in older vs younger subjects across all treatment arms Serious adverse reactions were generally reported at a higher frequency in the older subjects than in the younger subjects across all treatment arms. MM Maintenance Therapy: Overall, 10% (106/1,018) of patients were 65 years of age or older, while no patients were over 75 years of age. Grade 3 or 4 adverse reactions were higher in the lenalidomide capsules arm (more than 5% higher) in the patients 65 years of age or older versus younger patients. The frequency of Grade 3 or 4 adverse reactions in the Blood and Lymphatic System Disorders were higher in the lenalidomide capsules arm (more than 5% higher) in the patients 65 years of age or older versus younger patients. There were not a sufficient number of patients 65 years of age or older in lenalidomide capsules maintenance studies who experienced either a serious adverse reaction, or discontinued therapy due to an adverse reaction to determine whether elderly patients respond relative to safety differently from younger patients. MM After At Least One Prior Therapy : Of the 703 MM patients who received study treatment in Studies 1 and 2, 45% were age 65 or over while 12% of patients were age 75 and over. The percentage of patients age 65 or over was not significantly different between the lenalidomide/dexamethasone and placebo/dexamethasone groups. Of the 353 patients who received lenalidomide/dexamethasone, 46% were age 65 and over. In both studies, patients > 65 years of age were more likely than patients ≤ 65 years of age to experience DVT, pulmonary embolism, atrial fibrillation, and renal failure following use of lenalidomide capsules. No differences in efficacy were observed between patients over 65 years of age and younger patients. Of the 148 patients with del 5q MDS enrolled in the major study, 38% were age 65 and over, while 33% were age 75 and over. Although the overall frequency of adverse reactions (100%) was the same in patients over 65 years of age as in younger patients, the frequency of serious adverse reactions was higher in patients over 65 years of age than in younger patients (54% vs. 33%). A greater proportion of patients over 65 years of age discontinued from the clinical studies because of adverse reactions than the proportion of younger patients (27% vs.16%). No differences in efficacy were observed between patients over 65 years of age and younger patients. Of the 134 patients with MCL enrolled in the MCL trial, 63% were age 65 and over, while 22% of patients were age 75 and over. The overall frequency of adverse reactions was similar in patients over 65 years of age and in younger patients (98% vs. 100%). The overall incidence of grade 3 and 4 adverse reactions was also similar in these 2 patient groups (79% vs. 78%, respectively). The frequency of serious adverse reactions was higher in patients over 65 years of age than in younger patients (55% vs. 41%). No differences in efficacy were observed between patients over 65 years of age and younger patients. FL or MZL in Combination: Overall, 48% (282/590) of patients were 65 years of age or older, while 14% (82/590) of patients were over 75 years of age. The overall frequency of adverse reactions was similar in patients 65 years of age or older and younger patients for both studies pooled (98%). Grade 3 or 4 adverse reactions were higher in the lenalidomide capsules arm (more than 5% higher) in the patients 65 years of age or older versus younger patients (71% versus 59%). The frequency of Grade 3 or 4 adverse reactions were higher in the lenalidomide capsules arm (more than 5% higher) in the patients 65 years of age or older versus younger patients in the Blood and Lymphatic System Disorders (47% versus 40%) and Infections and Infestations (16% versus 11%). Serious adverse reactions were higher in the lenalidomide capsules arm (more than 5% higher) in the patients 65 years of age or older versus younger patients (37% versus 18%). The frequency of serious adverse reactions were higher in the lenalidomide capsules arm (more than 5% higher) in the patients 65 years of age or older versus younger patients in Infections and Infestations (15% versus 6%). Since elderly patients are more likely to have decreased renal function, care should be taken in dose selection. Monitor renal function.
Overdosage
There is no specific experience in the management of lenalidomide overdose in patients with MM, MDS, MCL, FL, or MZL. In dose-ranging studies in healthy subjects, some were exposed to up to 200 mg (administered 100 mg BID) and in single-dose studies, some subjects were exposed to up to 400 mg. Pruritus, urticaria, rash, and elevated liver transaminases were the primary reported AEs. In clinical trials, the dose-limiting toxicity was neutropenia and thrombocytopenia.
Description
Lenalidomide, a thalidomide analogue, is an immunomodulatory agent with antiangiogenic and antineoplastic properties. The chemical name is 3-(4-amino-1-oxo 1,3-dihydro-2 H -isoindol-2-yl) piperidine-2,6-dione and it has the following chemical structure: 3-(4-amino-1-oxo 1,3-dihydro-2 H -isoindol-2-yl) piperidine-2,6-dione The empirical formula for lenalidomide is C 13 H 13 N 3 O 3 , and the gram molecular weight is 259.3. Lenalidomide is a cream to light yellow color powder. It is soluble in organic solvent/water mixtures, and buffered aqueous solvents. Lenalidomide is more soluble in organic solvents and low pH solutions. Solubility was significantly lower in less acidic buffers, ranging from about 0.4 to 0.5 mg/ml. Lenalidomide has an asymmetric carbon atom and can exist as the optically active forms S(-) and R(+), and is produced as a racemic mixture with a net optical rotation of zero. Lenalidomide is available in 2.5 mg, 5 mg, 10 mg, 15 mg, 20 mg, and 25 mg capsules for oral administration. Each capsule contains lenalidomide as the active ingredient and the following inactive ingredients: anhydrous lactose. The capsule shell ingredients common to all strengths are gelatin and titanium dioxide. Additionally, the 20 mg capsule contains FD&C Blue #1, FD&C Yellow #6, and iron oxide yellow. Each capsule is printed with black ink, which includes black iron oxide, potassium hydroxide, propylene glycol, shellac, and strong ammonia solution. 1
Mechanism of action
12.1 Mechanism of Action Lenalidomide is an analogue of thalidomide with immunomodulatory, antiangiogenic, and antineoplastic properties. Cellular activities of lenalidomide are mediated through its target cereblon, a component of a cullin ring E3 ubiquitin ligase enzyme complex. In vitro , in the presence of drug, substrate proteins (including Aiolos, Ikaros, and CK1α) are targeted for ubiquitination and subsequent degradation leading to direct cytotoxic and immunomodulatory effects. Lenalidomide inhibits proliferation and induces apoptosis of certain hematopoietic tumor cells including MM, mantle cell lymphoma, and del (5q) myelodysplastic syndromes, follicular lymphoma and marginal zone lymphoma in vitro . Lenalidomide causes a delay in tumor growth in some in vivo nonclinical hematopoietic tumor models including MM. Immunomodulatory properties of lenalidomide include increased number and activation of T cells and natural killer (NK) cells leading to direct and enhanced antibody-dependent cell-mediated cytotoxicity (ADCC) via increased secretion of interleukin-2 and interferon-gamma, increased numbers of NKT cells, and inhibition of pro-inflammatory cytokines (e.g., TNF-α and IL-6) by monocytes. In MM cells, the combination of lenalidomide and dexamethasone synergizes the inhibition of cell proliferation and the induction of apoptosis. The combination of lenalidomide and rituximab increases ADCC and direct tumor apoptosis in follicular lymphoma cells and increases ADCC in marginal zone lymphoma cells compared to rituximab alone in vitro .
