Multiple Myeloma Kyprolis Study in Newly Diagnosed Disease Doesn’t Meet Primary Endpoint—PFS
Amgen announced top-line results of the phase III CLARION trial, which evaluated an investigational regimen of Kyprolis (carfilzomib), melphalan and prednisone (KMP) versus Velcade() (bortezomib), melphalan and prednisone (VMP) for 54 weeks in patients with newly diagnosed multiple myeloma who were ineligible for hematopoietic stem-cell transplant.
The trial did not meet the primary endpoint of superiority in progression-free survival (PFS) (median PFS 22.3 months for KMP versus 22.1 months for VMP, HR = 0.91, 95 percent CI, 0.75 – 1.10). While the data for overall survival, a secondary endpoint, are not yet mature, the observed hazard ratio (KMP versus VMP) was 1.21 (95 percent CI, 0.90 – 1.64). Neither result was statistically significant.
Overall, the adverse events in the KMP arm were consistent with the known safety profile of Kyprolis. The incidence of Grade 3 or higher adverse events was 74.7 percent in the KMP arm and 76.2 percent in the VMP arm. Fatal treatment-emergent adverse events occurred in 6.5 percent of KMP patients and 4.3 percent of VMP patients. The incidence of Grade 2 or higher peripheral neuropathy, a secondary endpoint, was 2.5 percent in the KMP arm and 35.1 percent in the VMP arm.
These data will be submitted to a future medical conference and for publication, … Continue reading CCL Oct 2016 – Kyprolis Study in Newly Diagnosed Disease Doesn’t Meet Primary Endpoint—PFS
