Zanubrutinib and Rituximab Followed by R-DHAOx Then Maintenance With Zanubrutinib for Newly-Diagnosed MCL
Study Details
Study Description
Brief Summary
This phase 2 trial studies the efficacy and safety of zanubrutinib plus rituximab followed by R-DHAOx (rituximab, dexamethasone, cytarabine and oxaliplatin) regimen then maintenance with zanubrutinib for newly-diagnosed Mantle Cell Lymphoma (MCL).

Experimental: zanubrutinib, rituximab, consolidation chemotherapy and zanubrutinb maintenance Part A (Zanubrutinib and Rituximab): Patients receive zanubrutinib on days 1-28 and rituximab on day 1. Treatment cycles repeat every 28 days for up to 12 cycles in the absence of disease progression or unacceptable toxicity or until patients achieve CR. PART B (Consolidation chemotherapy of R-DHAOx): Patients receive R-DHAOx regimen every 21 days for up to 4 cycles in the absence of disease progression or unacceptable toxicity. Elderly patients (> 65 years old) and patients who achieved CR and minimal residual disease negative after PART B receive zanubrutinb maintenance therapy. Young patients (<65 years old) who achieved CR but minimal residual disease positive after PART B can receive autologous stem cell transplantation and then zanubrutinb maintenance therapy. Patients with PD, SD or PR after PART B quit the trial. ZANUBRUTINB MAINTENANCE: Patients receive zanubrutinib every day for up to one year. |
