IntroductionCOMMODORE 2 (NCT04434092) and COMMODORE 1 (NCT04432584) are global, randomized, open-label, multicenter Phase III trials evaluating crovalimab (crova) vs eculizumab (ecu) in patients (pts) with PNH. COMMODORE 2 tested the non-inferiority of crova vs ecu in C5i-naive pts and demonstrated that crova was non-inferior to ecu for hemolysis control, transfusion avoidance, breakthrough hemolysis, and hemoglobin stabilization (Röth EHA 2023; #S181). In both studies, crova was well tolerated for both C5i-naive and C5i-experienced pts (Röth EHA 2023; #S181, Scheinberg EHA 2023; #S183). To investigate the efficacy of crova vs ecu from a pt perspective, PRO tools were used to assess fatigue, PNH-related symptoms, functioning, and global health status/quality of life (GHS/QoL) among COMMODORE 2 and COMMODORE 1 pts.

Background: BCL-2 inhibition with venetoclax has proved to be highly effective treatment for patients with CLL. However, when administered to patients with CLL who have a high tumor burden, venetoclax is associated with an elevated risk of tumor lysis syndrome (TLS). Because of this risk, venetoclax is initiated with a gradual, 5-week dose ramp-up, requiring close laboratory monitoring over an extended period. Lisaftoclax (APG-2575) is a novel, potent, selective BCL-2 inhibitor under clinical development for hematologic malignancies (HMs). Preliminary data in 18 patients with CLL treated in a first-in-human study suggested the feasibility of an abbreviated ramp-up of lisaftoclax that might also result in a lower incidence of neutropenia (Ailawadhi et al, J Clin Oncol 39, 2021; abstr 7502).
