Abstract CT149: Copanlisib in patients with relapsed or refractory indolent B-cell lymphoma: Primary results of the pivotal Chronos-1 study
Notice bibliographique
Résumé
Abstract Introduction: There are limited treatment options for patients with indolent B-cell lymphoma who have relapsed or are refractory to standard therapies. Copanlisib is an intravenously administered pan-Class I phosphatidylinositol 3-kinase (PI3K) inhibitor with predominant activity against PI3K-α and PI3K-δ isoforms. We report here the primary results from a pivotal phase II study (NCT01660451, part B). Methods: Patients with indolent B-cell non-Hodgkin lymphoma (4 subtypes: follicular [FL], marginal zone [MZL], small lymphocytic [SLL] and lymphoplasmacytoid/Waldenström macroglobulinemia [LPL-WM]) and relapsed after, or refractory to, ≥2 prior lines of treatment were eligible. Previous treatment had to include rituximab and an alkylating agent. Copanlisib (60 mg, I.V.) was intermittently administered on days 1, 8 and 15 of a 28-day cycle. The primary efficacy endpoint was objective tumor response rate (ORR) as assessed per independent radiologic review (Cheson et al., JCO 20:579, 2007). Results: The full analysis set comprised 142 patients, of which 141 patients had indolent lymphoma (FL/MZL/SLL/LPL-WM: 104/23/8/6). At the time of primary analysis, median duration of treatment was 22 weeks (range 1-105); 46 patients remained on treatment. The most common treatment-related AEs (all grade/grade 3+) were transient hyperglycemia (49%/40%) and hypertension (29%/23%). Other AEs of interest included neutropenia (25%/19%), diarrhea (18%/4%), lung infection (14%/11%), pneumonitis (7%/1.4%), and colitis (0.7%/0.7%). No colonic perforations occurred. There were two non-fatal opportunistic infections. Laboratory toxicities of interest were principally grade-1, including alanine aminotransferase (23% all-grade/19% grade-1) and aspartate aminotransferase (28%/25%). There were 6 deaths, 3 of which were attributed to copanlisib: lung infection, respiratory failure, and a thromboembolic event. The ORR was 59.2%, including 12.0% complete response (CR) and 47.2% partial response (PR), with stable disease in 29.6% of patients and progressive disease in 2.1% of patients. In the FL subset, the ORR was 58.7%, including 14.4% CR and 44.2% PR. In the MZL subset, the ORR was 69.6%, including 8.7% CR and 60.9% PR. The estimated Kaplan-Meier (KM) median duration of response in the full analysis set was 687 days (range 0-687) and 370 days (range 0-687) in the FL subset. The KM-estimate of median PFS was 340 days (range 0-736). Median overall survival had not yet been reached. Conclusions: Treatment of patients with relapsed or refractory indolent B-cell lymphoma with copanlisib resulted in durable tumor responses. Administration of copanlisib had a manageable safety profile, with low rates of severe hepatic enzymopathy, diarrhea or inflammatory events, as well as low rates of opportunistic infections, fatal infections or other fatal serious adverse events.
