RecruitingPhase 2Drug trialOrelabrutinib and Rituximab With Optional Autologous Hematopoietic Stem Cell Transplantation in MCL TreatmentThis multicenter, open-label, trial aims to evaluate the efficacy and safety of orelabrutinib in combination with rituximab with optional autologous hematopoietic stem cell transplantation in patients with non-high-risk mantle cell lymphoma (MCL). The primary objective is to assess the optimal 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.
