Research Article: Real-world effectiveness and safety of carfilzomib, pomalidomide, and dexamethasone in relapsed/refractory multiple myeloma: a retrospective analysis from China
Abstract:
Pomalidomide, a next-generation immunomodulatory drug (IMiD), and carfilzomib, a novel proteasome inhibitor (PI), have been separately approved in combination regimens for relapsed/refractory multiple myeloma (RRMM). However, real-world data, particularly for Chinese RRMM patients with prior-line treatment, including lenalidomide and bortezomib, remain limited.
We retrospectively analyzed RRMM patients treated with KPd between October 2022 and December 2024 at two Chinese centers.
This study included 34 patients who received KPd. The median age was 65 years. All patients were bortezomib-exposed, 91.2% were lenalidomide-exposed (and refractory), and 50.0% were daratumumab-exposed. The overall response rate (ORR) was 82.4% and was significantly influenced by high-risk cytogenetics, prior daratumumab exposure, and the receipt of ? 3 prior lines of therapy. The median progression-free survival (PFS) was 13 months, with a 2-year PFS rate of 40.3%. Hematologic toxicities were the most common adverse events (AEs) (73.5%), and grade 3/4 AEs occurred in 58.8% of patients.
KPd exhibited substantial effectiveness in this real-world cohort of heavily pretreated Chinese RRMM patients, including those with lenalidomide-refractory disease. However, the high incidence of hematologic toxicities necessitates careful monitoring and management.
