In 2023, the therapy for newly diagnosed MM with the longest progression free survival (PFS) is an induction with a combination of an anti-CD38 mAb, a proteasome inhibitor, lenalidomide, and dexamethasone (Voorhees et al. 2020), followed by consolidation with high-dose melphalan and autologous stem cell transplantation, and then maintenance lenalidomide until progression. Here, CD38 is linked to Miyoshi myopathy.
