Amgen today announced the submission of a supplemental New Drug Application (sNDA) to the U.S. Food and Drug Administration (FDA) for Kyprolis (carfilzomib) for injection to seek an expanded indication for the treatment of patients with a form of blood cancer, relapsed multiple myeloma, who have received at least one prior therapy. Kyprolis currently has accelerated approval in the U.S. for the treatment of patients with relapsed multiple myeloma as a monotherapy. 

The sNDA is based on data from the global Phase 3 ENDEAVOR trial. The ENDEAVOR study is the first of two head-to-head Phase 3 trials of Kyprolis versus Velcade (bortezomib). Relapsed multiple myeloma patients treated with Kyprolis and dexamethasone in the ENDEAVOR study lived twice as long without their disease worsening, demonstrating statistically and clinically significant superiority over Velcade (median progression-free survival [PFS] 18.7 months versus 9.4 months, HR=0.53, 95 percent CI, 0.44 – 0.65; p<0.0001).  

"Submission of this new sNDA for Kyprolis is important because if approved, it will mean more treatment options for patients with this serious disease. Multiple myeloma has historically been one of the most difficult to treat diseases because of the inherent complexities related to the recurring pattern of remission and relapse," said Sean E. Harper, M.D., executive vice president of Research and Development at Amgen. "The ENDEAVOR study showed that patients who had failed at least one prior therapy were half as likely to see their disease worsen if they received Kyprolis. This is yet another data set that illustrates Kyprolis' potential to extend the time patients live without their disease progressing and improve the depth and duration of a response."
