First-line therapy with bendamustine/prednisone/bortezomib-A GMMG trial for non-transplant eligible symptomatic multiple myeloma patients
Abstract
Objectives: The German-speaking Myeloma Multicenter Group (GMMG) conducted this trial to investigate efficacy and safety of the three-drug combination bendamustine/prednisone/bortezomib (BPV) as first-line therapy for elderly patients with multiple myeloma (MM).
Methods: Elderly MM patients requiring first-line therapy and not eligible for intensive treatment were enrolled in this phase IIb multicenter study. Patients were treated with BPV regimen for a maximum of nine cycles.
Results: Forty-six patients were included in the trial with a median age of 76 years. Nineteen patients had renal impairment at baseline. The ORR was 78.8% for patients treated with 3 and more BPV cycles and 71.1% for all evaluable patients. The median progression-free survival was 25 months, and overall survival at 24 months was 83.3%. The clinical benefit rate including MR was 91.2%. In patients with renal impairment at baseline, a renal response was observed in 11 pts. with complete recovery of the renal function in six patients. The most frequent CTC grade 3/4 AEs experienced by patients were hematological (17.5%) and infectious (9.8%) complications. No new safety signals were observed for the study drugs under investigation.
Conclusions: Bendamustine/prednisone/bortezomib may serve as a first-line regimen for transplant-ineligible elderly MM patients in particular for patients with renal impairment requiring a fast and durable renal response.
