Clinical Study of OR for Second-line Treatment of Refractory MZL

Официальное название

Prospective, Multicenter, Single-arm Clinical Study of Orelabrutinib Plus Rituximab for Second-line Treatment of Relapsed/Refractory Marginal Zone Lymphoma

Обзор

The goal of this clinical trial is to test the overall response rate of Orelabrutinib combined with rituximab (OR regimen) for second-line treatment of relapsed/refractory marginal zone lymphoma.

Вмешательства

• Препарат Orelabrutinib combined with rituximab
  This is a single-arm trial. Patients with relapsed/refractory marginal zone lymphoma will be treated with the OR regimen. The treatment plan is as follows: Orelabrutinib 150mg oral administration once a day, Day 1-21; Rituximab 375mg/m² intravenous infusion, Day 1. Each cycle is 21 days. PET-CT evaluation will be conducted after 4 cycles. If a partial response (PR) or better is achieved, the patient will receive further treatment with the OR regimen for an additional 4 cycles before transitionin
