News Release - April 4, 2007
ECOG Phase III Newly Diagnosed Multiple Myeloma Trial (E4A03) Reports LENALIDOMIDE Plus Low-Dose Dexamethasone Suggests Survival Advantage for Patients with Multiple MyelomaSUMMIT, N.J., April 4 (HSMN NewsFeed) -- Celgene Corporation (Nasdaq: CELG ) announced that the Eastern Cooperative Oncology Group (ECOG) has reported that its Data Monitoring Committee's (DMC) review of preliminary results from a large, randomized clinical trial for patients with newly diagnosed Multiple Myeloma has found that the use of a low dose of dexamethasone (Decadron) in combination with lenalidomide suggests survival advantage for patients when compared to the higher, standard-dose of dexamethasone that is used in combination with lenalidomide to treat the disease.
REVLIMID (lenalidomide) is approved by the U.S. Food and Drug Administration for use as a treatment in combination with standard-dose dexamethasone for patients with Multiple Myeloma who have received at least one prior therapy. REVLIMID is also approved for the treatment of patients with transfusion-dependent anemia due to low- or intermediate-1-risk myelodysplastic syndromes (MDS) associated with a deletion 5q cytogenetic abnormality with or without additional cytogenetic abnormalities. REVLIMID recently received a positive opinion from the European Medicines Agency (EMEA) for use in combination with dexamethasone as a treatment for patients with Multiple Myeloma who have received at least one prior therapy.
1. POTENTIAL FOR HUMAN BIRTH DEFECTS.
LENALIDOMIDE IS AN ANALOGUE OF THALIDOMIDE. THALIDOMIDE IS A KNOWN HUMAN TERATOGEN THAT CAUSES SEVERE LIFE-THREATENING HUMAN BIRTH DEFECTS. IF LENALIDOMIDE IS TAKEN DURING PREGNANCY, IT MAY CAUSE BIRTH DEFECTS OR DEATH TO AN UNBORN BABY. FEMALES SHOULD BE ADVISED TO AVOID PREGNANCY WHILE TAKING REVLIMID® (lenalidomide).
Special Prescribing Requirements
BECAUSE OF THIS POTENTIAL TOXICITY AND TO AVOID FETAL EXPOSURE TO REVLIMID® (lenalidomide), REVLIMID® (lenalidomide) IS ONLY AVAILABLE UNDER A SPECIAL RESTRICTED DISTRIBUTION PROGRAM. THIS PROGRAM IS CALLED "RevAssist®". UNDER THIS PROGRAM, ONLY PRESCRIBERS AND PHARMACISTS REGISTERED WITH THE PROGRAM CAN PRESCRIBE AND DISPENSE THE PRODUCT. IN ADDITION, REVLIMID® (lenalidomide) MUST ONLY BE DISPENSED TO PATIENTS WHO ARE REGISTERED AND MEET ALL THE CONDITIONS OF THE RevAssist® PROGRAM.
2. HEMATOLOGIC TOXICITY (NEUTROPENIA AND THROMBOCYTOPENIA).
THIS DRUG IS ASSOCIATED WITH 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)
3. DEEP VENOUS THROMBOSIS AND PULMONARY EMBOLISM.
This drug has demonstrated a significantly increased risk of deep venous thrombosis (DVT) and pulmonary embolism (PE) in patients with Multiple Myeloma who were treated with REVLIMID® (lenalidomide) combination 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® (lenalidomide) 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.

ADDITIONAL WARNINGS: HEMATOLOGIC TOXICITY
In the pooled Multiple Myeloma studies Grade 3 and 4 hematologic toxicities were more frequent in patients treated with the combination of REVLIMID® (lenalidomide) and dexamethasone than in patients treated with dexamethasone alone. Patients on therapy should have their complete blood counts monitored every 2 weeks for the first 12 weeks and then monthly thereafter. Patients may require dose interruption and/or dose reduction.
Hypersensitivity: REVLIMID® (lenalidomide) is contraindicated in any patients who have demonstrated hypersensitivity to the drug or its components.
Renal impairment: REVLIMID® (lenalidomide) is substantially excreted by the kidney, so the risk of toxic reactions may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it would be prudent to monitor renal function.
Nursing mothers: It is not known whether REVLIMID® (lenalidomide) 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.
In the REVLIMID® (lenalidomide)/dexamethasone treatment group, 151 patients (45%) underwent at least one dose interruption with or without a dose reduction of REVLIMID® (lenalidomide) compared to 21% in the placebo/dexamethasone treatment group. Of these patients who had one dose interruption with or without a dose reduction, 50% in the REVLIMID® (lenalidomide)/dexamethasone treatment group underwent at least one additional dose interruption with or without a dose reduction compared to 21% in the placebo/dexamethasone treatment group.
Other adverse events reported in Multiple Myeloma patients (REVLIMID® (lenalidomide)/dexamethasone vs dexamethasone/placebo): constipation (39% vs 19%), fatigue (38% vs 37%), insomnia (32% vs 37%), muscle cramp (30% vs 21%), diarrhea (29% vs 25%), neutropenia (28% vs 5%), anemia (24% vs 17%), asthenia (23% vs 25%), pyrexia (23% vs 19%), nausea (22% vs 19%), headache (21% vs 21%), peripheral edema (21% vs 19%), dizziness (21% vs 15%), dyspnea (20% vs 15%), tremor (20% vs 7%), decreased weight (18% vs 14%), thrombocytopenia (17% vs 10%), rash (16% vs 8%), back pain (15% vs 14%), hyperglycemia (15% vs 14%), and muscle weakness (15% vs 15%).
Other adverse reactions reported in del 5q MDS patients (REVLIMID®): diarrhea (49%), pruritus (42%), rash (36%), fatigue (31%), constipation (24%), nausea (24%), nasopharyngitis (23%), arthralgia (22%), pyrexia (21%), back pain (21%), peripheral edema (20%), cough (20%), dizziness (20%), headache (20%), muscle cramp (18%), dyspnea (17%), and pharyngitis (16%).
DOSAGE AND ADMINISTRATION:
Dosing is continued or modified based upon clinical and laboratory findings. Dosing modifications are recommended to manage Grade 3 or 4 neutropenia or thrombocytopenia or other Grade 3 or 4 toxicity judged to be related to lenalidomide. For other Grade 3 or 4 toxicities judged to be related to lenalidomide, hold treatment and restart at next lower dose level when toxicity has resolved to less than or equal to Grade 2.

About Multiple Myeloma
Multiple Myeloma (also known as myeloma or plasma cell myeloma) is a cancer of the blood in which malignant plasma cells are overproduced in the bone marrow. Plasma cells are white blood cells that help produce antibodies called immunoglobulins that fight infection and disease. However, most patients with Multiple Myeloma have cells that produce a form of immunoglobulin called paraprotein (or M protein) that does not benefit the body. In addition, the malignant plasma cells replace normal plasma cells and other white blood cells important to the immune system. Multiple Myeloma cells can also attach to other tissues of the body, such as bone, and produce tumors. The cause of the disease remains unknown.
