PG - 899-906 LID - 10.1182/blood-2014-02-556308 [doi] AB - Standard carfilzomib (20 mg/m(2) cycle 1, 27 mg/m(2) thereafter; 2- to 10-minute infusion) is safe and effective in relapsed or refractory multiple myeloma (R/RMM). We report phase 2 results of carfilzomib 20 mg/m(2) on days 1 to 2 of cycle 1, 56 mg/m(2) thereafter (30-minute infusion), in R/RMM with the option of adding dexamethasone (20 mg) for suboptimal response/progression. Forty-four patients enrolled, all having prior bortezomib and immunomodulatory drugs and a median of 5 prior regimens. Of 42 response-evaluable patients, 23 (55%) achieved at least partial response (PR). Median (95% confidence interval) duration of response, progression-free, and overall survival were 11.7 (6.7-14.7), 4.1 (2.5-11.8), and 20.3 months (6.4-not estimable), respectively. High-risk cytogenetics did not impact outcomes. Treatment was active in bortezomib-refractory subgroups, but these patients tended to have poorer outcomes. Four/10 patients with prior allogeneic transplant achieved at least PR. Of 6 patients who responded, progressed and had dexamethasone added, 4 achieved at least stable disease. The most frequent grade 3/4 adverse events (AEs) possibly related to carfilzomib included lymphopenia (43%), thrombocytopenia (32%), hypertension (25%), pneumonia (18%), and heart failure (11%). Seven patients (16%) discontinued treatment due to AEs. Carfilzomib 56 mg/m(2) +/- dexamethasone was tolerable and provided durable responses. This trial was registered at www.clinicaltrials.gov as #NCT01351623. CI - (c) 2014 by The American Society of Hematology.
