Orelabrutinib Combined With Obinutuzumab and Lenalidomide (OGL Regimen) as First-line Treatment for Marginal Zone Lymphoma：a Multicenter Prospective Single Arm Trial

Обзор

This is a multicenter prospective single arm phase II study, and the purpose of this study is to evaluate the safety and efficacy of orelabrutinib combined with obinutuzumab and lenalidomide in untreated marginal zone lymphoma. The primary objective was the best complete response rate (CRR).

Подробное описание

Marginal zone lymphomas (MZL) are a type of lymphoma that originates from the marginal zone tissue of the lymphoid follicles (Mucosa-associated lymphoid tissue, MALT), and include three subtypes: MALT lymphoma, nodal MZL, and splenic MZL. The incidence of MZL is second only to diffuse large B-cell lymphoma (DLBCL) and follicular lymphoma (FL), accounting for approximately 7.8% of all non-Hodgkin lymphomas (NHL). MZL is considered an indolent lymphoma, with patients generally having a better overall survival prognosis. Despite this, some patients still face the challenges of disease relapse or transformation into large cell lymphoma, leading to a poor prognosis.

We conduct this prospective, phase II, single-arm clinical study to initially explore the efficacy and safety of Orelabrutinib combined with obinutuzumab and lenalidomide in patients with previously untreated marginal zone lymphoma. The patients will be treated with 6 cycles of OGL regimen. Patients with CR/PR after 6 cycles of OGL treatment will be treated with 6 cycles of single-agent orelabrutinib regimen.
