Orelabrutinib

This is a three-arm, multicenter, randomized controlled trial. Eligible participants will be randomized to one of three induction regimens via stratified block randomization at a 2:2:1 ratio. Induction regimens: Arm A: Teniposide + orelabrutinib + rituximab + methotrexate (MTX) + dexamethasone, administered in 21-day cycles. Arm B: Orelabrutinib + rituximab + MTX + dexamethasone, administered in 21-day cycles. Arm C: Rituximab + MTX + dexamethasone, administered in 21-day cycles. Participants achieving complete response (CR) or unconfirmed complete response (CRu) post-induction will proceed to consolidation therapy, with options including: MTX + rituximab (once every 3 months for 1 year); high-dose chemotherapy followed by autologous stem cell transplantation (ASCT); dose-reduced whole brain radiotherapy; or other modalities (as determined by the investigator).

This multicenter, open-label, trial aims to evaluate the efficacy and safety of orelabrutinib plus lisaftoclax and rituximab in patients with 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.

This study aims to evaluate the safety and efficacy of orelabrutinib (O) in combination with obinutuzumab (G) and short-course venetoclax (V) in patients with treatment-naïve MCL.
