Summary
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).
