Researchers are evaluating the effectiveness, safety, and patient-reported outcomes of standard treatments for people with relapsed or refractory multiple myeloma in real-world clinical settings. This study follows participants over 24 months to observe how current standard care works for those who have previously received treatment for this condition. The research includes participants who meet specific diagnostic criteria and have measurable disease based on recognized myeloma guidelines. The study does not involve any experimental treatment; instead, it observes patients receiving standard care as decided by their doctors. Participants include those who have undergone multiple prior therapies, including specific drug classes and targeted treatments, depending on the study period. The study covers different periods with slightly varied eligibility and treatment histories, including a group starting talquetamab treatment for relapsed or refractory multiple myeloma. Participants will be monitored for up to 52 months to evaluate their response to treatment, including overall response rates. Researchers will collect data on their health status, treatment history, and patient-reported outcomes. Safety and effectiveness will be assessed based on clinical evaluations and disease progression as determined by their healthcare providers throughout the study period.
