SWOG Phase III Trial Reports REVLIMID(R) (lenalidomide) Plus Dexamethasone Achieves Superior Progression-Free Survival in Newly Diagnosed Multiple Myeloma Patients77% One-Year Progression-Free Survival In REVLIMID plus dexamethasone arm compared to 55% for dexamethasone alone
85% Overall Response Rate with REVLIMID plus dexamethasone compared to 51% in dexamethasone alone
BOUDRY, Switzerland--(HSMN NewsFeed)--Celgene International Sàrl (NASDAQ: CELG ) announced that results from the Southwest Oncology Group (SWOG) Phase III randomized, controlled trial evaluating REVLIMID (lenalidomide) and the steroid dexamethasone were presented for the first time at the 49th annual American Society of Hematology (ASH) Meeting. The SWOG (S0232) study (Abstract #77) evaluated the combination therapy of REVLIMID and dexamethasone in patients with newly diagnosed Multiple Myeloma and found that patients given the treatment regimen had superior response rates and progression-free survival compared to those who received dexamethasone alone.
According to Brian G.M. Durie, M.D., Chairman of the International Myeloma Foundation and co-chair of the SWOG Myeloma Committee, “REVLIMID with standard dose dexamethasone is among the most active up-front combination regimens against myeloma.”
Overall response rate in patients receiving REVLIMID and dexamethasone was 85.3% with 22.1% of patients achieving complete responses compared to 51.3% and 3.8%, respectively in the dexamethasone only group. Additionally, estimated one year progression-free survival was 77% in patients who received the combined therapy compared to 55% who received dexamethasone alone. The one-year overall survival rates in both arms of the study are among the highest ever reported (93% and 91%), influenced by the fact that patients in the dexamethasone only arm crossed over and received REVLIMID and dexamethasone, at the time of progression or when the study was halted.
“These results demonstrate that REVLIMID plus dexamethasone is an excellent treatment in newly diagnosed multiple myeloma,” said Dr. Durie. “Additionally, REVLIMID offers a quality of life advantage through its oral formulation and rare incidence of peripheral neuropathy, a treatment-limiting side effect.”
The SWOG trial permanently closed enrollment in May after the preliminary one-year survival results from the Eastern Cooperative Oncology Group (ECOG) Phase III study (E4A03) were released. The ECOG trial showed an unprecedented survival advantage in using REVLIMID and low-dose dexamethasone in newly diagnosed Multiple Myeloma patients.
Grade 3/4 adverse events were more frequent in Multiple Myeloma patients who received the combination of lenalidomide/dexamethasone compared to dexamethasone alone. Neutropenia (13.5%; 27/198) and infections (19.1%, 38/198) were the most frequently reported adverse events. DVT occurred in 25% of patients receiving REVLIMID and dexamethasone compared to 7% with dexamethasone alone, however, with the use of aspirin as a prophylaxis the DVT events were 14% and 12% respectively.
REVLIMID is an oral medication currently approved in the United States, the EU and Switzerland for treatment of patients with Multiple Myeloma in combination with dexamethasone who have received at least one prior therapy. REVLIMID is also approved in the United States 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. REVLIMID has obtained Orphan Drug designation in the EU, U.S., Switzerland and Australia.
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.
