Official title:
A Perspective and Multicenter Phase II Trial of Tirelizumab Combined With R2-ICE Regimen (Rituximab, Lenalidomide, Ifosfamide, Carboplatin, Etoposide) in the Treatment of Refractory or Relapse DLBCL or HGBL
This study was a prospective, multi-center, single-arm, Phase II clinical study. Compared with the literature data, objective response rate (ORR) and complete response rate (CR) were the primary endpoint, and 1-year and 2-year progression-free survival (PFS) and 2-year overall survival (OS) were the secondary endpoint. To evaluate the efficacy and safety of TR2-ICE sequential Tirelarizin, lenalidomide alone, or both maintenance therapy in the rescue of patients with relapsed and refractory diffuse large B or high-grade B-cell lymphoma.
All patients eligible for inclusion were treated with TR2-ICE, and the first efficacy evaluation was conducted after the second course of treatment. If the patient can achieve complete response (CR), partial response (PR), and disease stability (SD), the clinical benefit is considered, and the TR2-ICE treatment regimen is continued. The second efficacy assessment was performed after the 4th course of treatment. If patients achieved complete response (CR) or partial response (PR) compared to baseline, the clinical treatment was considered effective and the TR2-ICE treatment regimen was continued. After the completion of six courses of induction chemotherapy, an end-of-course assessment was performed. Patients with CR and PR can choose to undergo autologous hematopoietic stem cell transplantation consolidation therapy, or lenalidomide or Tirelarizin monotherapy or both combination maintenance therapy. If patients still had SD after four courses of treatment or PD at any time during the study, they were dropped out of the study and given salvage therapy. ;
