FDA grants REVLIMID® NDA approval

December 28, 2005

Celgene Corporation (NASDAQ: CELG) announced that the U.S. Food and Drug Administration (FDA) granted approval of REVLIMID (lenalidomide) which is indicated 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 will be available through a REVLIMID Education and Prescribing Safety Program, called RevAssistsm via contracted pharmacies.

"The clinical data from a Phase II trial of 148 patients demonstrated that Revlimid can reduce or even eliminate the need for transfusions in many patients with del 5q MDS," said Dr. Alan List, Professor of Oncology and Medicine, and Chief Division of Hematologic Malignancies Hematologic Malignancies at H. Lee Moffitt Cancer Center, Tampa, Florida, and the study's lead investigator. "I am extremely pleased with the FDA's action today."

The safety profile for REVLIMID has shown that neutropenia and/or thrombocytopenia were the most common adverse event (AE) and that patients may require a dose adjustment. Other observed and common AE's include diarrhea, pruritis, rash, fatigue, constipation, nausea, nasopharyngitis, arthralgia, pyrexia, back pain, peripheral edema, cough, dizziness, headache, muscle cramp, dyspnea, and pharyngitis.

"Being able to use an oral therapy such as REVLIMID to treat del 5q MDS could reduce or even eliminate the need for red blood cell transfusions in MDS patients," said Dr. John Bennett, Professor of Oncology in Medicine, Pathology, and Laboratory Medicine, University of Rochester.

"The FDA approval of REVLIMID offers a new therapeutic option to this particular group of patients with myelodysplastic syndromes," said Graham Burton, M.D., SVP, Regulatory Affairs and Pharmacovigilance for Celgene.

The timing of this approval will result in most initial shipments of REVLIMID to be distributed in early 2006. This later than anticipated approval has also resulted in an increase in pre-launch expenses of approximately $5 million, with 2005 full-year adjusted earnings per share now expected to be approximately $0.36-$0.38 per diluted share.

Safety notice: REVLIMID® (lenalidomide) Capsules 5 mg & 10 mg

WARNING: 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 LENALIDOMIDE. BECAUSE OF THIS POTENTIAL TOXICITY AND TO AVOID FETAL EXPOSURE TO REVLIMID (lenalidomide), IT IS ONLY AVAILABLE UNDER A SPECIAL RESTRICTED DISTRIBUTION PROGRAM. THIS PROGRAM IS CALLED "REVASSISTSM". UNDER THIS PROGRAM, ONLY PRESCRIBERS AND PHARMACISTS REGISTERED WITH THE PROGRAM ARE ALLOWED TO PRESCRIBE AND DISPENSE THE PRODUCT. IN ADDITION, PATIENTS MUST AGREE TO COMPLY WITH THE REQUIREMENTS OF THE REVASSISTSM PROGRAM TO RECEIVE DRUG.

WARNING: HEMATOLOGICAL TOXICITY (NEUTROPENIA AND THROMBOCYTOPENIA)
LENALIDOMIDE IS ASSOCIATED WITH SIGNIFICANT NEUTROPENIA AND THROMBOCYTOPENIA. PATIENTS SHOULD HAVE THEIR CBC CHECKED WEEKLY FOR THE FIRST 8 WEEKS OF REVLIMID® (lenalidomide) TREATMENT AND AT LEAST MONTHLY THEREAFTER TO MONITOR FOR CYTOPENIAS. MOST DELETION 5q MDS PATIENTS STUDIED REQUIRED A DOSE ADJUSTMENT FOR NEUTROPENIA AND THROMBOCYTOPENIA.

WARNING: DEEP VEIN THROMBOSIS AND PULMONARY EMBOLISM REVLIMID® (lenalidomide) HAS DEMONSTRATED SIGNIFICANT RISK OF DEEP VEIN THROMBOSIS AND PULMONARY EMBOLISM IN SOME PATIENTS WITH CERTAIN MEDICAL CONDITIONS.

IMPORTANT SAFETY INFORMATION
Hypersensitivity: REVLIMID® (lenalidomide) is contraindicated in any patients who have demonstrated hypersensitivity to the drug or its components.

Other adverse events: Other most frequently reported adverse events were diarrhea, pruritis, rash, fatigue, constipation, nausea, nasopharyngitis, arthralgia, pyrexia, back pain, peripheral edema, cough, dizziness, headache, muscle cramp, dyspnea, and pharyngitis. REVLIMID® (lenaliodomide) is substantially excreted by the kidney, so the risk of toxic reactions may be greater in patients with impaired renal function.

About Myelodysplastic Syndromes
Myelodysplastic syndromes (MDS) are a group of hematologic malignancies that affect approximately 300,000 people worldwide. Myelodysplastic syndromes occur when blood cells remain in an immature or "blast" stage within the bone marrow and never develop into mature cells capable of performing their necessary functions. Eventually, the bone marrow may be filled with blast cells suppressing normal cell development. According to the American Cancer Society, 10,000 to 20,000 new cases of MDS are diagnosed each year in the United States, with mean survival rates ranging from approximately six months to six years for the different classifications of MDS. MDS patients must often rely on blood transfusions to manage symptoms of anemia and fatigue and may develop life-threatening iron overload and/or toxicity from frequent transfusions, thus underscoring the critical need for new therapies targeting the cause of the condition rather than simply managing its symptoms.

About Deletion 5q Chromosomal Abnormality
Chromosomal (cytogenetic) abnormalities are detected in more than half of patients with myelodysplastic syndrome (MDS), and involve a deletion in all or part of one or more specific chromosomes. The most common cytogenetic abnormalities in MDS are deletions in the long arm of chromosomes 5, 7, and 20. Another common abnormality is an extra copy of chromosome 8. A deletion involving the 5q chromosome may be involved in 20 percent to 30 percent of all MDS patients. The World Health Organization has also recently identified a unique subset of MDS patients with a "5q- Syndrome" where the only chromosomal abnormality is a specific portion of the 5q chromosome.
