Orelabrutinib Plus Lisaftoclax and Rituximab in Untreated Mantle Cell Lymphoma With High-Risk Disease
Trial Parameters
Brief Summary
This multicenter, open-label, trial aims to evaluate the efficacy and safety of orelabrutinib plus lisaftoclax and rituximab in patients with high-risk mantle cell lymphoma (MCL). The primary objective is to assess the optimal complete response (CR) rate during the induction phase, with secondary objectives including progression-free survival (PFS), overall survival (OS), objective response rate (ORR), and safety. Exploratory analysis will investigate the correlation between tumor biomarkers and treatment efficacy.
Eligibility Criteria
Inclusion Criteria: * Diagnosed with MCL (mantle cell lymphoma) through flow cytometry or histopathology, and has not received prior treatment. * Age \> 14 years of age, both genders are eligible. * Ann Arbor stage II-IV; for stage II subjects, those who require systemic therapy based on the investigator's judgment are eligible. * At least one measurable lesion. * Any one of the following high-risk factors is present: MIPI score of 6-11, Ki67 \> 30%, TP53 mutation/loss or p53 protein expression \>50%, blastic or pleomorphic variation. * Laboratory tests (blood routine, liver and kidney function) meet the following requirements: a) Blood routine: White blood cell count ≥3.0×10\^9/L, absolute neutrophil count ≥1.5×10\^9/L, hemoglobin ≥90g/L, platelet count ≥75×10\^9/L. b) Liver function: Transaminases ≤2.5 times the upper limit of normal, bilirubin ≤1.5 times the upper limit of normal. c) Serum creatinine 44-133 mmol/L. * The investigator judges that the subject's life expectancy is grea
