Kyprolis® Significantly Improves Overall Survival Compared To Velcade®

The ENDEAVOR trial results were updated at the 16th International Myeloma Workshop in New Delhi.

The trial demonstrated that Kyprolis (Carfilzomib) not only significantly extended progression-free survival compared to Velcade (Bortezomib), but also overall improved overall survival, making it a clinically meaningful advance in the treatment of relapsed or refractory multiple myeloma.  Patients with relapsed or refractory multiple myeloma treated with Kyprolis® and dexamethasone lived 7.6 months longer than those treated with Velcade® and dexamethasone.1

Multiple myeloma is a cancer of plasma cells, which are a special type of white blood cell that are part of the body’s immune system. In the U.S., approximately 70,000 people are living with multiple myeloma and approximately 24,000 new individuals are diagnosed annually. Patients with multiple myeloma have increased numbers of abnormal plasma cells that may produce increased quantities of dysfunctional antibodies detectable in the blood and/or urine. Patients with multiple myeloma who have become refractory, or resistant have limited treatment options. There is no standard treatment for these patients and they typically have a poor prognosis.

Kyprolis belongs to a class of drugs known as proteasome inhibitors. They work by preventing the breakdown of protein in cancer cells, triggering their death.  Normal cellular processes include the breakdown of proteins that are no longer being used. It is important for cells to get rid of the used proteins to function normally. Proteasomes, structures found in healthy cells, play an important role in the breakdown and recycling of these used proteins.

The ENDEAVOR study is the first of two head-to-head studies for Kyprolis versus Velcade, an established proteasome inhibitor, currently approved to treat multiple myeloma. The randomized ENDEAVOR (RandomizEd, OpeN Label, Phase 3 Study of Carfilzomib Plus DExamethAsone Vs Bortezomib Plus DexamethasOne in Patients With Relapsed Multiple Myeloma) trial of 929 patients evaluated Kyprolis in combination with low-dose dexamethasone, versus Velcade with low-dose dexamethasone in patients whose multiple myeloma has relapsed after at least one, but not more than three prior therapeutic regimens. This study was conducted at 235 sites worldwide.2
