Clinical Trials
Previously Treated MM
Two randomized studies were conducted to evaluate the efficacy and safety of REVLIMID. These multicenter, multinational,
double-blind, placebo-controlled studies compared REVLIMID plus oral pulse high-dose dexamethasone (dex) therapy to dex
therapy alone in patients with MM who had received at least one prior treatment.
In both studies, patients in the REVLIMID/dex group took 25 mg of REVLIMID once daily on Days 1-21 of each 28-day cycle.
Patients in both treatment groups took 40 mg of dex once daily on Days 1-4, 9-12, and 17-20 of each 28-day cycle for the
first 4 cycles of therapy. The dose of dex was reduced to 40 mg once daily on Days 1-4 of each 28-day cycle after the
first 4 cycles of therapy. In both studies, treatment was to continue until disease progression.
The primary efficacy endpoint in both studies was time to progression (TTP). TTP was defined as the time from randomization
to the first occurrence of progressive disease.

Significantly superior TTP with REVLIMID/dexamethasone (REV/dex) vs placebo/dex in 2 studies (P<0.001)
- Median TTP was:
- Study 1: 13.9 months (95% CI, 9.5-18.5) with REV/dex vs 4.7 months (95% CI, 3.7-4.9) with placebo/dex
- Study 2: 12.1 months (95% CI, 9.5-NE) with REV/dex vs 4.7 months (95% CI, 3.8-4.8) with placebo/dex
- Results of 2 randomized, double-blind, placebo-controlled studies comparing REV/dex to placebo/dex in
patients who had received at least 1 prior treatment. TTP, time from randomization to the first
occurrence of disease progression based on the myeloma response criteria developed by Bladé, et al.,
treatment discontinuation due to disease progression according to the investigator (whether or not
confirmed by the Bladé, et al. criteria), or death due to disease progression while on treatment. (TTP was
measured to the date of last visit or to death if death occurred on or before treatment discontinuation)1,2
- TTP was based on data up to cutoff (June 7, 2005, for Study 1; August 3, 2005, for Study 2)

Important dosing information
- Lenalidomide is primarily excreted unchanged by the kidney. Since elderly patients are more likely to have decreased renal function, care should be taken in dose selection. Monitor renal function
- Monitor CBCs every 2 weeks for the first 12 weeks, then monthly thereafter
- Treatment is continued or modified based on clinical and laboratory findings
- Dose modification guidelines are recommended to manage Grade 3/4 neutropenia or thrombocytopenia, or other Grade 3/4 toxicity judged to be related to lenalidomide
- Patients may require dose interruption and/or reduction
- Patients may require the use of blood product support and/or growth factors

Important Safety Information
WARNING: FETAL RISK, HEMATOLOGIC TOXICITY, and DEEP VEIN THROMBOSIS AND PULMONARY EMBOLISM
Do not use REVLIMID 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 death to a developing baby. In women of childbearing potential, obtain 2 negative pregnancy tests before
starting REVLIMID treatment. Women of childbearing potential must use 2 forms of contraception or continuously abstain from heterosexual sex
during and for 4 weeks after REVLIMID treatment. To avoid fetal exposure to lenalidomide, REVLIMID is only available under a restricted
distribution program called "RevAssist®."
Information about the RevAssist program is available at www.REVLIMID.com or
by calling the manufacturer’s toll-free number 1-888-423-5436.
HEMATOLOGIC TOXICITY (NEUTROPENIA AND THROMBOCYTOPENIA)
REVLIMID can cause significant neutropenia and thrombocytopenia. Eighty percent of patients with del 5q MDS 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 MDS 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)
DEEP VEIN THROMBOSIS AND PULMONARY EMBOLISM
REVLIMID has demonstrated a significantly increased risk of deep vein thrombosis (DVT) and pulmonary embolism (PE) in patients
with MM who were treated with REVLIMID and dexamethasone therapy. Patients and physicians are advised to be observant for the signs
and symptoms of thromboembolism. Patients should be instructed to seek medical care if they develop symptoms such as shortness
of breath, chest pain, or arm or leg swelling. It is not known whether prophylactic anticoagulation or antiplatelet therapy
prescribed in conjunction with REVLIMID may lessen the potential for venous thromboembolic events. The decision to take prophylactic
measures should be done carefully after an assessment of an individual patient’s underlying risk factors.
CONTRAINDICATIONS:
Pregnancy Category X:
- Lenalidomide is contraindicated in pregnant women and women capable of becoming pregnant. Females of childbearing potential
may be treated with lenalidomide provided adequate precautions are taken to avoid pregnancy
Allergic Reactions:
- REVLIMID is contraindicated in patients who have demonstrated hypersensitivity (e.g., angioedema, Stevens-Johnson syndrome,
toxic epidermal necrolysis) to lenalidomide
WARNINGS AND PRECAUTIONS:
Fetal Risk:
- REVLIMID is an analogue of thalidomide, a known human teratogen that causes life-threatening human birth defects.
An embryofetal development study in non-human primates 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. If REVLIMID is used during pregnancy, it may cause birth defects
or death to a developing baby
- Females of childbearing potential must be advised to avoid pregnancy while on REVLIMID. Two effective contraceptive
methods should be used during therapy, during therapy interruptions, and for at least 4 weeks after completing therapy
- Male Patients: It is not known whether lenalidomide is present in the semen of patients receiving the drug.
Therefore, males receiving REVLIMID must always use a latex condom during any sexual contact with females
of childbearing potential, even if they have undergone a successful vasectomy
Reproductive Risk and Special Prescribing Requirements (RevAssist® Program):
- Because of this potential toxicity and to avoid fetal exposure, REVLIMID is only available under a special
restricted distribution program called "RevAssist." Prescribers and pharmacists registered with the program
can prescribe and dispense the product to patients who are registered and meet all the conditions of
the RevAssist® program
Hematologic Toxicity—Multiple Myeloma:
- REVLIMID can cause significant neutropenia and thrombocytopenia
- Patients taking REVLIMID for MM should have their complete blood counts monitored every 2 weeks for
the first 12 weeks and then monthly thereafter
- In the pooled MM studies Grade 3 and 4 hematologic toxicities were more frequent in patients treated with
the combination of REVLIMID and dexamethasone than in patients treated with dexamethasone alone
- Patients may require dose interruption and/or dose reduction
Deep Vein Thrombosis:
- Venous thromboembolic events (predominantly deep venous thrombosis and pulmonary embolism) have occurred in patients
with MM treated with lenalidomide combination therapy and patients with MDS treated with lenalidomide monotherapy
Allergic Reactions:
- Angioedema and serious dermatologic reactions including Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN)
have been reported. These events can be fatal. Patients with a prior history of Grade 4 rash associated with thalidomide treatment
should not receive REVLIMID. REVLIMID interruption or discontinuation should be considered for Grade 2-3 skin rash. REVLIMID must be
discontinued for angioedema, Grade 4 rash, exfoliative or bullous rash, or if SJS or TEN is suspected, and should not be resumed
following discontinuation for these reactions
Tumor Lysis Syndrome:
- Fatal instances of tumor lysis syndrome have been reported during treatment with lenalidomide. The patients at risk of
tumor lysis syndrome are those with high tumor burden prior to treatment. These patients should be monitored closely
and appropriate precautions taken
Tumor Flare Reaction:
- Tumor flare reaction has occurred during investigational use of lenalidomide for chronic lymphocytic leukemia (CLL) and lymphoma,
and is characterized by tender lymph node swelling, low grade fever, pain and rash. Treatment of CLL or lymphoma with lenalidomide
outside of a well-monitored clinical trial is discouraged
DRUG INTERACTIONS:
- Erythropoietic agents, or other agents, that may increase the risk of thrombosis, such as estrogen containing therapies,
should be used with caution in MM patients receiving lenalidomide with dexamethasone
USE IN SPECIAL POPULATIONS:
Nursing Mothers:
- It is not known whether REVLIMID is excreted in human milk
- Because of the potential for adverse reactions in nursing infants, a decision should be made whether to discontinue nursing
or the drug, taking into account the importance of the drug to the mother
Geriatric Use:
- Since elderly patients are more likely to have decreased renal function, care should be taken in dose selection. Monitor renal function
Renal Impairment:
- Since REVLIMID is primarily excreted unchanged by the kidney, adjustments to the starting dose of REVLIMID are recommended to
provide appropriate drug exposure in patients with moderate or severe renal impairment (CLcr < 60 mL/min) and in patients on dialysis
ADVERSE REACTIONS:
