Phase 12 Open-Label Study of Oral BGB-16673 for Treating B-Cell Blood Cancers Including Lymphomas and Leukemias

What this Trial Is About

Researchers are evaluating BGB-16673, an oral drug, in adults with various types of B-cell malignancies such as marginal zone lymphoma, follicular lymphoma, mantle cell lymphoma, chronic lymphocytic leukemia, Waldenstrm macroglobulinemia, diffuse large B-cell lymphoma, and Richters transformation. This study includes Phase 1 dose finding and safety expansion, followed by Phase 2 expansion cohorts to determine recommended doses and further assess safety and efficacy. The study is divided into several parts, starting with Phase 1 dose escalation to find safe dosage levels, including monotherapy dose escalation and safety expansion in selected doses. Phase 2 involves expansion cohorts where participants receive the recommended doses identified in Phase 1 for further safety and efficacy evaluation. Some cohorts include participants who have not received prior BTK inhibitors, and Japanese participants are also enrolled to assess safety. Treatments are orally administered. Participants will undergo regular assessments including monitoring for adverse events, disease response, and drug concentration levels in the blood at various time points. Researchers will measure outcomes such as overall response rate and progression-free survival over approximately three years. Safety and tolerability will be closely tracked, and quality of life questionnaires will be completed at scheduled intervals. Participation may last several years, including follow-up periods to monitor long-term effects.
