Two hundred and sixty-six patients received single agent carfilzomib twice weekly for 3 out of 4 weeks. The study's primary endpoint was overall response rate (ORR; ≥partial response) and secondary endpoints included clinical benefit response rate (≥minimal response), duration of response (DOR), time to progression, progression-free survival, overall survival (OS), and safety.
ORR was 23.7 percent with median DOR of 7.8 months. Median OS was 15.6 months. Adverse events (AEs) were manageable without cumulative toxicities. The researchers concluded that durable responses and an acceptable tolerability profile in this heavily-pretreated population demonstrate the potential of carfilzomib to offer meaningful clinical benefit.
Phase 1/2 Results for Frontline Therapy for Newly Diagnosed Multiple Myeloma Patients
David H. Vesole, M.D., Ph.D., F.A.C.P., Co-Chief and Director of Research served as co-author of a study published on June 4th in Blood, which involved researchers from six leading cancer centers. The multi-center, open-label phase 1/2 study looked at carfilzomib in combination with lenalidomide and low-dose dexamethasone (CRd) as a frontline treatment for multiple myeloma.
"Triple-agent regimens with bortezomib, lenalidomide, and/or thalidomide are currently the preferred frontline strategy for newly diagnosed multiple myeloma. However, maintaining dose levels over time can be limited by the treatments' emerging toxicities," said Dr. Vesole. "This study demonstrated that the combination of carfilzomib, lenalidomide and dexamethasone is well tolerated and highly active for these patients."
The researchers enrolled 53 patients with newly-diagnosed multiple myeloma who had symptomati
