Combination of Zanubrutinib, Rituximab and Venetoclax in Patients With Previously Untreated Follicular Lymphoma

Официальное название

Safety and Efficacy of Zanubrutinib in Combination With Rituximab and Venetoclax in Previously Untreated Follicular Lymphoma: An Open Label, Phase 2 Study

Обзор

This is a single center, open label, single arm phase II clinical trial. The objective of this study is to assess the feasibility and efficacy of zanubrutinib combined with venetoclax and Rituximab in patients with previously untreated follicular lymphoma (FL) .

Подробное описание

Follicular lymphoma (FL)is the most common inert non Hodgkin's lymphoma (iNHL). Their natural courses are slow but highly variable. The standard first-line treatment of advanced FL is based on rituximab. Whether combined with chemotherapy or not, it can induce lasting remission, but it is usually incurable. Although the first-line immunochemotherapy regimen has high efficacy, it also has high toxicity. Cytotoxic chemotherapy is related to many side effects, including bone marrow suppression and immunosuppression, gastrointestinal and cardiac toxicity, neurotoxicity and the occurrence of secondary tumors. About 20% of FL patients relapse within 2 years after first-line chemotherapy. The overall prognosis of these patients is poor. This clinical trial aims to evaluate the feasibility and efficacy of free-chemotherapy regimen (zanubrutinib combined with venetoclax and Rituximab) in patients with previously untreated follicular lymphoma.
