Summary
Brief summary (as posted)
This multicenter, open-label, randomized controlled trial aims to evaluate the efficacy and safety of Orelabrutinib in combination with Bendamustine and Rituximab (OBR) versus Bendamustine and Rituximab (BR) in patients with intermediate- to high-risk mantle cell lymphoma (MCL) who are ineligible for transplantation. The primary objective is to assess the complete response (CR) rate during the induction phase, with secondary objectives including progression-free survival (PFS), overall survival (OS), objective response rate (ORR), and safety. Exploratory analysis will investigate the correlation between tumor biomarkers and treatment efficacy.
