Study of Clinical Outcomes in Adults with RelapsedRefractory Multiple Myeloma Treated with Teclistamab or Talquetamab Outside Clinical Trials

What this Trial Is About

This observational study aims to describe the use of teclistamab and talquetamab in treating patients with relapsed or refractory multiple myeloma RRMM outside of clinical trial settings. It collects real-world data to better understand how these treatments are used and their outcomes in typical healthcare environments. The study enrolls participants who have received at least one dose of teclistamab or talquetamab outside clinical trials during specified time periods from before December 2022 through December 2025. No study interventions are administered instead, researchers analyze existing medical records to document treatment details and patient experiences with these therapies. Participants medical records are reviewed to capture baseline characteristics, response rates, time to response, duration of response, survival outcomes, safety management, and treatment use up to 40 months. The study focuses on collecting comprehensive retrospective data without requiring active treatment or additional procedures, providing insight into real-world treatment patterns and outcomes for RRMM patients.
