A Study to Compare the Effects of Elranatamab (PF 06863135) Versus Standard of Care (SOC) in Patients With Multiple Myeloma (MM) in Germany and US

The purpose of the study is to understand how well elranatamab (PF-06863135) may be used for relapsed refractory multiple myeloma (RRMM). MM is a type of cancer that begins in plasma cells (white blood cells that produce antibodies). Sometimes MM might improve at first, but then gets resistant to the treatment and starts growing again (known as relapsed refractory). This study medicine will be compared with standard-of-care (SOC) therapies. SOC are treatments that are accepted by medical experts as a proper treatment for a certain type of disease and that are widely used by doctors in real world. For people receiving elranatamab, the study doctors will use data from the other clinical trial (MagnetisMM-3). The study doctors will also use data from multiplemany real-world sources (TherapyMonitor MM Germany and Flatiron Health), for SOC in clinical practice. This study does not seek any participants for enrollment. The study doctors will compare the experiences of people receiving elranatamab to people receiving SOC therapies. This way, it will help the study doctors to know how well elranatamab can be used for RRMM treatment.
