Real-World Clinical Outcomes in Relapsed/Refractory Multiple Myeloma Treated With Pomalidomide Regimens

This retrospective observational study will use data from the OneOncology United States database to evaluate clinical outcomes in adults with relapsed/refractory multiple myeloma who received pomalidomide-containing or non-pomalidomide-containing treatment as second-line or third-line therapy after prior exposure to lenalidomide and a proteasome inhibitor.
