BOUDRY, Switzerland, Jun 06, 2010 (BUSINESS WIRE) --Celgene International Sàrl (NASDAQ: CELG) announced clinical data from an investigational study of patients with multiple myeloma who were younger than 65 years old and received either lenalidomide (REVLIMID), melphalan and prednisone (MPR) or melphalan plus autologous stem cell transplant (MEL200) following an induction treatment of lenalidomide plus low-dose dexamethasone (Rd) were presented at the American Society of Clinical Oncology annual meeting.
In the study, 402 patients received four 28-day cycles of Rd as an induction therapy. Patients were then randomized to receive either six 28-day courses of MPR or tandem autologous stem cell transplant (MEL200). Upon completion of this regimen, patients were randomized to either continuous lenalidomide or no continuous therapy until relapse.
Following the Rd induction phase, 86% (318/370) of patients achieved a partial response (PR) or better and 37% (137/370) achieved at least a very good partial response (VGPR). After randomization, 55% of those who received at least three cycles of MPR (64/117) achieved at least a VGPR, with 13% (15/117) achieving a complete response (CR). Fifty-three percent of patients who received the first of the tandem autologous stem cell transplant (MEL200) (65/122) achieved at least a VGPR, with 16% (20/122) (p=0.82) achieving a CR.
Progression-free survival was the primary endpoint of the trial. At a median follow-up of 14 months the 1-year progression free survival rate was 91% for both the MPR and autologous stem cell transplant (MEL200) arms (p=0.77). Additionally, the 1-year overall survival rate for the MPR arm was 97% compared to 98% (p=0.27) for the MEL200 arm.
In the study, the most common grade 3 or 4 adverse events were neutropenia (Rd 9%, MPR 48%, MEL200 84%), thrombocytopenia (Rd 3%, MPR 8%, MEL200 84%), infection (Rd 5%, MPR 0%, MEL200 17%) and gastrointestinal events (MPR 0%, MEL200 22%).
These data are from an investigational study. REVLIMID is not approved as a treatment for patients newly diagnosed with multiple myeloma.
REVLIMID is an IMiDs compound. REVLIMID and other IMiDs continue to be evaluated in over 100 clinical trials. The IMiDs pipeline is covered by a comprehensive intellectual property estate of issued and pending patent applications in the US, EU and other regions, including composition-of- matter and use patents.
REVLIMID is approved in combination with dexamethasone for the treatment of patients with multiple myeloma who have received at least one prior therapy in nearly 50 countries, encompassing Europe, the Americas, the Middle-East and Asia, and in combination with dexamethasone for the treatment of patients whose disease has progressed after one therapy in Australia and New Zealand.
REVLIMID is also approved in the United States, Canada and several Latin American countries, as well as Malaysia and Israel, for transfusion-dependent anemia due to low- or intermediate-1-risk MDS associated with a deletion 5q cytogenetic abnormality with or without additional cytogenetic abnormalities. Marketing Authorization Applications are currently being evaluated in a number of other countries.
REVLIMID(lenalidomide) in combination with dexamethasone is indicated for the treatment of multiple myeloma patients who have received at least one prior therapy.
REVLIMID (lenalidomide) is indicated for patients with transfusion-dependent anemia due to low- or intermediate-1-risk MDS associated with a deletion 5q cytogenetic abnormality with or without additional cytogenetic abnormalities.
Important Safety Information
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).
Male Patients:It is not known whether lenalidomide is present in the semen of patients receiving the drug.Therefore, males receiving REVLIMID® (lenalidomide) must always use a latex condom during any sexual contact with females of childbearing potential even if they have undergone a successful vasectomy.
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. In the U.S., 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.

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.
