Phase 3 Randomized, Double-blind, Placebo Controlled, Multicenter Study to Compare the Efficacy and Safety of Lenalidomide (CC-5013) Plus R-CHOP Chemotherapy (R2-CHOP) Versus Placebo Plus R-CHOP Chemotherapy in Subjects With Previously Untreated Activated B-Cell Type Diffuse Large B-Cell Lymphoma
This research study is for patients with newly diagnosed Diffuse Large B-cell Lymphoma (DLBCL) of the activated B-cell (ABC) type who have not yet been treated. DLBCL is a cancer of a type of blood cell called B-lymphocytes. B lymphocytes are part of the body's immune system. There are different types of DLBCL. About a third of newly diagnosed DLBCL cancers are the ABC type. It has been observed that treatment does not work as well for patients with the ABC type compared to patients with other DLBCL types who receive standard treatment. However, at this time both ABC type and other DLBCL type patients receive the same standard treatments.
Patients with DLBCL who are otherwise healthy are usually treated first with the chemotherapy drug combination called R-CHOP. The drugs in this combination are "R" for rituximab, "C" for cyclophosphamide, "H" for doxorubicin which has a chemical name of hydroxydaunomycin, "O" for vincristine which has a trade name of oncovin, and "P" for prednisone. Depending on the local practice where you are treated, R-CHOP may be given for 6 or 8 cycles. A cycle could last for 14 or 21 days. The R-CHOP drug combination is approved for the treatment of DLBCL of all types, including ABC type. R-CHOP is standard care. In this study, R-CHOP is given for 6 cycles. Each cycle will last 21 days. It is called R-CHOP21 x 6. In this study, the standard treatment is R-CHOP21 x 6.
This study will test the standard R-CHOP21 against R-CHOP21 plus lenalidomide. The purpose is to see whether adding lenalidomide works better and is as safe as R-CHOP by itself. This study is only for patients with ABC type DLBCL who have not yet been treated. Lenalidomide is not approved for use in DLBCL. Its use in this disease is experimental. In this study, the experimental treatment is lenalidomide + R-CHOP21 x 6.
This study will use a gene expression profile (GEP) test to see if a patient has the ABC type. The results of this GEP test affect whether you may be treated on this study. Because the performance of this test has not been proven, it is for investigational use only, and is still under development. This means the GEP test is an experimental test.
