**Connect® MM- The Multiple Myeloma Disease Registry** The Connect® MM Registry is a study to learn more about multiple myeloma (MM), a type of blood cancer. It looks at how this disease affects people and how it is treated in real life. To join, you must be newly diagnosed with MM and be over 18 years old. You also need to agree to fill out some questionnaires about your health. For those who have already had treatment but their disease has worsened, you can still join if you start new treatment within 90 days. The study does not accept people who are part of other similar studies or have had treatments for other types of MM, like smoldering MM or MGUS, which are less severe forms. **Key Points:** - Participants must be newly diagnosed with symptomatic MM or have started a new treatment after previous treatment failed. - Must be willing to fill out health questionnaires. - Cannot be in another MM study at the same time.
