Подробное описание

Marginal Zone Lymphoma (MZL) is a group of B-cell malignancies believed to originate from B lymphocytes, typically found in the marginal zones of lymphoid follicles in the spleen, lymph nodes, and mucosa-associated lymphoid tissues. Exploring more effective, low-toxicity treatment plans for MZL patients is a scientifically valuable and clinically significant attempt. With the development of new drugs, new drug regimens have become prominent in the treatment of MZL, and there is an increasing amount of research data on BTK inhibitors in the field of MZL. The BTK inhibitor Orelabrutinib has shown good efficacy in MZL and has been approved by the NMPA for the treatment of MZL in patients who have received at least one prior treatment.

This is a multi-center, prospective cohort study. The main purpose of study is to evaluate the efficacy and safety of Orelabrutinib combined with Zuberitamab in the initial treatment of MZL. After receiving 6 cycles of ZO regimen induction therapy, patients were treated with Orelabrutinib combined with Zuberitamab (administered every 2 cycles) for 6 cycles or had disease progression or toxicity intolerance. Main efficacy indicators Complete response rate (CR) at the end of combination therapy.
