Evaluation of Maintenance With Bortezomib Plus Daratumumab (V-Dara) After Induction With Bortezomib, Melphalan, Prednisone Plus Daratumumab (VMP-Dara) in Newly Diagnosed Multiple Myeloma (MM) Patients Non-eligible for autoSCT

This is a prospective, observational, single group and multicenter study to describe the effectiveness and safety of maintenance with V-Dara after induction with the VMP-Dara regimen in newly diagnosed MM patients who are not eligible for ASCT. Patients will be enrolled in the study during a regularly scheduled office visit in clinical practice (screening and enrollment visit) and followed during 3-4 years in what will be called the Observational Phase. During this phase, the patient will be followed by his/her doctor as per routine clinical practice, according to his/her disease. The patient will not suffer any changes in his/her treatment or follow-up due to his/her participation in the study. The patient will receive standard clinical practice and he/she will not do any other study-specific visit. During this 3-4-year observational phase, the patient might discontinue V or V-Dara,depending on toxicity, efficacy or due to other medical reasons, according to his/her physician decision.
