Официальное название

Zanubrutinib Plus Rituximab as Front-line Treatment for Mucosa-associated Lymphoid Tissue Lymphoma (MALT): a Single-arm, Open-label, Multicenter, Phase II Study（ZAMA）

Обзор

This is a prospective, single-arm, multicenter, phase II clinical trial to evaluate the efficacy and safety of Zanubrutinib in combination with Rituximab as a first-line treatment for patients with mucosa-associated lymphoid tissue (MALT) extranodal marginal zone lymphoma.

Подробное описание

The purpose of this study is to evaluate the efficacy and safety of Zanubrutinib in combination with Rituximab as a first-line treatment for patients with mucosa-associated lymphoid tissue (MALT) extranodal marginal zone lymphoma.

Treatrment:

1. Rituximab: 375 mg/m², administered once a week in Cycle 1 (C1) and on Day 1 (D1) of Cycles 2-6 (C2-C6). 2. Zanubrutinib: 160 mg, administered twice daily from Day 1 to Day 28 (D1-D28). Each cycle lasts 28 days. After 6 cycles of treatment, patients who achieve complete remission (CR) will end treatment and enter observation follow-up. Patients with partial remission (PR) or stable disease (SD) will receive 2 additional cycles.

The primary study endpoint is the complete remission rate of Zanubrutinib in combination with Rituximab in the treatment of newly diagnosed mucosa-associated lymphoid tissue (MALT) extranodal marginal zone lymphoma.
