Advanced Physician Search: Mantle Cell

This study aims to evaluate the efficacy and safety of an induction regimen combining Bendamustine, Rituximab, Cytarabine (AraC), and Zanubrutinib (BRAZAN), followed by maintenance therapy with Zanubrutinib and Rituximab with or without Sonrotoclax in participants with Mantle Cell Lymphoma (MCL). The names of the study drugs involved in this study are: * bendamustine (a type of alkylating agent) * rituximab (a type of monoclonal antibody) * cytarabine (a type of antineoplastic) * zanubrutinib (a type of kinase inhibitor) * sonrotoclax (a type of BCL2 inhibitor)

Drug: Rituximab, Drug: Zanubrutinib, Drug: Sonrotoclax

This phase III trial tests whether continuous or intermittent zanubrutinib after achieving a complete remission (CR) with rituximab works in older adult patients with mantle cell lymphoma (MCL) who have not received treatment in the past (previously untreated). Rituximab is a monoclonal antibody that may interfere with the ability of cancer cells to grow and spread. Zanubrutinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. When zanubrutinib is used in MCL, the current standard of care is to continue administering the drug indefinitely until disease progression. This continuous treatment comes with clinical as well as financial toxicity, which could be especially detrimental in older patients. For patients who achieve a CR after initial zanubrutinib plus rituximab therapy, it may be safe and equally effective to stop treatment and restart zanubrutinib upon disease progression rather than continuing indefinitely in previously untreated older adult patients with MCL.
