Официальное название

Zanubrutinib Combined With Rituximab and Lenalidomide (ZR2) Versus R2 Regimen in the Treatment of Newly Diagnosed Follicular Lymphoma: A Randomized, Multicenter, Open-Label Phase II Clinical Study

Обзор

Primary Objective: To compare the complete response rate (CR rate) after induction treatment between the ZR2 regimen and the R2 regimen.\<br/\>\<br/\>Secondary Objectives: To compare the objective response rate (ORR) after induction treatment, progression-free survival (PFS), progression of disease within 24 months (POD24) rate, duration of response (DOR), overall survival (OS), treatment-related adverse events (AEs), and patient quality of life between the two groups.\<br/\>\<br/\>Exploratory Objectives: To compare the histological .transformation (HT) rate at disease progression, minimal residual disease (MRD) negativity rate, changes in tumor microenvironment (TME) biomarkers, and the relationship between genetic biomarkers and efficacy/prognosis between the two groups; to further reveal the unique pattern of systemic immune status remodeling by the ZR2 regimen and identify potential efficacy-predictive biomarkers.
