Carfilzomib (Kyprolis, Onyx Pharmaceuticals, South San Francisco, CA) is a proteasome inhibitor that recently received accelerated FDA approval as single-agent treatment for relapsed or refractory multiple myeloma (RRMM),¹ as well as designation as a “Preferred Regimen” for salvage therapy according to the National Comprehensive Cancer Network (NCCN) guidelines.² Carfilzomib differs structurally and mechanistically from bortezomib; it functions by irreversibly inhibiting chymotrypsin-like activity of the constitutive proteasome and the immunoproteasome and offers a novel treatment option for patients with advanced MM.³

Introduction

The proteasome inhibitor carfilzomib is a promising new agent for the treatment of multiple myeloma (MM). Data presented at the 53rd Annual Meeting of the American Society of Hematology (ASH) highlighted a role for this agent in both the frontline and relapsed and/or refractory settings.
