Clinical Trial Summary

This research study is evaluating a combination of four drugs -- lenalidomide, bortezomib, dexamethasone and elotuzumab -- as therapy for newly diagnosed multiple myeloma.

Description:

This research study is a Phase II clinical trial testing the safety and effectiveness of an investigational drug (in this case elotuzumab) in combination with lenalidomide, bortezomib and dexamethasone to learn more about the side effects of this regimen and whether it is effective in newly diagnosed multiple myeloma.

"Investigational" means that the drug elotuzumab and the combination of this agent with lenalidomide, bortezomib, and dexamethasone are being studied. It also means that the the U.S. Food and Drug Administration (FDA) has not yet approved elotuzumab for the treatment of cancer. The drugs, lenalidomide, bortezomib, and dexamethasone are approved by the FDA. Participants in this trial will have the option to undergo autologous stem cell transplantation (ASCT) following initial therapy with elotuzumab, lenalidomide, bortezomib, and dexamethasone. ASCT is a standard of care in the treatment of multiple myeloma. All participants, including those who undergo ASCT and those who choose not to, will receive what is referred to as "maintenance therapy" - or continuous treatment - after the initial cycles of treatment with elotuzumab, lenalidomide, bortezomib, and dexamethasone. The specific maintenance regimen will be determined by risk category.
