Zillion: Zanubrutinib Combined With Chemotherapy for Newly Diagnosed CNS Lymphoma

Официальное название

Clinical Study on the Efficacy and Safety of Zanubrutinib Combined With Chemotherapy for Continuous Maintenance Treatment of Newly Diagnosed Central Nervous System Lymphoma

Обзор

Subjects who met the inclusion/exclusion criteria were included in the experimental group after signing the informed consent form. One course of Z(R)-MTX(TMZ) treatment was given. After the results of the second-generation sequencing were reported, selinisol was added to the original treatment plan for those with TP53 mutations, and the original treatment plan was continued for those without TP53 mutations. Each course of treatment lasts for three weeks. A mid-term assessment is conducted after three courses of treatment, and a final assessment is carried out after six courses of treatment. After the mid-term or final assessment: If the PR is not achieved or the disease progresses at any time, the subjects are withdrawn from the group and receive salvage treatment. If the subjects achieve CR or PR, they enter maintenance treatment and continue with zanubrutinib for 2 years. For young patients (\< 65 years old), they can choose whether to receive ASCT as consolidation treatment according to their personal will, and then follow up and observe until 3 years have passed. SD/PD patients receive subsequent treatment after being judged by the researchers

Вмешательства

• Препарат Zanubrutinib + Rituximab + MTX ± Selinexor
  This is a single-arm interventional study. Participants will undergo an induction phase consisting of six 21-day cycles. During induction, all participants receive: Zanubrutinib 160 mg orally twice daily, Rituximab 375 mg/m² intravenous on Day 0, MTX 3.5 mg/m² intravenous on Days 1. Before the second treatment cycle, participants will be tested for TP53 mutation status. Participants who test positive for the TP53 mutation will receive Selinexor 40 mg orally on Days 1 weekly added to their trea
