PG - 428-435 LID - 10.1002/ajh.26088 [doi] AB - The maximum tolerated dose of the panobinostat and carfilzomib combination in patients with relapsed/refractory multiple myeloma (RRMM) was not reached in our previous dose-escalation study. We report additional dose levels in the phase I/II, single-arm, multicenter, standard 3 + 3 dose-escalation expansion-cohort study (NCT01496118). Patients with RRMM were treated with panobinostat 30 mg, carfilzomib 20/56 mg/m(2) (N = 3), or panobinostat 20 mg, carfilzomib 20/56 mg/m(2) (N = 33). Treatment cycles lasted 28 days; panobinostat: days 1, 3, 5, 15, 17, 19; carfilzomib: days 1, 2, 8, 9, 15, 16. For dose level 6 (DL 6), median age was 63 years (range, 49-91 years), 60.6% were male, 42.4% were high risk. Patients received a median of two prior therapies (range 1-7); proteasome inhibitors (PI; 100%), immunomodulatory imide drugs (IMiD; 78.8%), and stem cell transplant (36.4%); 48.5%, 51.1%, and 24.2% were refractory to prior PI or prior IMiD treatment or both, respectively. Patients completed a median of seven (range 1-40) treatment cycles. Overall response rate (primary endpoint) of evaluable patients in the expansion cohort (N = 32): 84.4%; clinical benefit rate: 90.6%. With a median follow-up of 26.1 months (range, 0-72.5 months), median (95% CI) progression-free survival, time-to-progression and overall survival of patients was 10.3 (6.1, 13.9), 11.7 (5.6, 14.5), and 44.6 (20.8, N/A) months, respectively. Common adverse events (AEs) included thrombocytopenia (78.8%), nausea (63.6%), fatigue (63.6%), diarrhea (51.5%), and vomiting (51.5%). Seven patients had serious treatment-related AEs. There was one treatment-related death. In conclusion, panobinostat plus carfilzomib is an effective steroid-sparing regimen for RRMM. CI - (c) 2021 The Authors.
