The US Food and Drug Administration (FDA) has approved the use of carfilzomib (Kyprolis) in combination with dexamethasone or lenalidomide plus dexamethasone to treat patients with relapsed or refractory multiple myeloma (MM) who have received 1 to 3 prior lines of therapy.

The FDA also approved use of carfilzomib as a single agent to treat patients with relapsed or refractory MM who have received 1 or more lines of therapy.

This decision converts to full approval the initial accelerated approval granted for single-agent carfilzomib in July 2012.

In July 2015, the FDA approved the use of carfilzomib in combination with lenalidomide and dexamethasone for the treatment of patients with relapsed MM who have received 1 to 3 prior lines of therapy.

The latest approval of carfilzomib is based on results from the phase 3 ENDEAVOR study.

Trial results

The ENDEAVOR trial included 929 MM patients whose disease had relapsed after 1 to 3 prior therapeutic regimens. The patients received either carfilzomib plus dexamethasone (n=464) or bortezomib plus dexamethasone (n=465) until disease progression.

The primary endpoint was progression-free survival. The median was 18.7 months in the carfilzomib arm and 9.4 months in the bortezomib arm. The hazard ratio was 0.53 (P<0.0001).

Overall survival data are not yet mature and continue to be monitored.

Treatment discontinuation due to adverse events and on-study deaths were comparable between the 2 treatment arms.

However, a number of known adverse events were reported at a higher rate in the carfilzomib arm than the bortezomib arm, including any-grade dyspnea (28% vs 13%), hypertension (25% vs 3%), pyrexia (27% vs 14%), cough (25% vs 15%), cardiac failure (8% vs 3%), and acute renal failure (8% vs 5%).

Carfilzomib is marketed as Kyprolis by Onyx Pharmaceuticals, Inc., a subsidiary of Amgen that holds development and commercialization rights to the drug globally, with the exception of Japan. For more information on the drug, visit www.kyprolis.com.
