Bone marrow samples were treated ex vivo with BCMA CAR T cells, TCEs (elranatamab, SAR442257), or activated T cells, and analyzed by flow cytometry. CD45 upregulation was validated in patient samples before and after idecabtagene vicleucel therapy (anti-BCMA CAR T-cell therapy), and by using in an in vivo mouse model of disseminated MM...Mechanistic studies implicated secreted HSP70, while bulk RNA-sequencing revealed increased LAG-3, IFN-γ signaling, and PD-L1 expression. These findings suggest T cell-redirecting therapy (TCRT) drives an immuno-evasive phenotype defined by CD45 upregulation and immune checkpoint activation, supporting combination strategies of TCRT with checkpoint inhibitors to overcome resistance in relapsed/refractory MM.

In newly diagnosed MM (NDMM), minimal residual disease (MRD)-adaptive consolidation with linvoseltamab in IMMUNOPLANT converted persistent MRD positivity to MRD negativity in all evaluable patients, supporting biologically guided treatment intensification...In early relapsed/refractory MM (RRMM), the pioneering phase III MajesTEC-3 trial demonstrated significant progression-free survival (PFS) and overall survival (OS) benefits with BsAb teclistamab plus daratumumab compared to other standard triplets, with response rates approaching those historically observed with chimeric antigen receptor (CAR) T cell therapy. A novel rational BsAb combination of BsAb elranatamab anda cereblon E3 ligase modulatory drug (CELMoD) iberdomide in MagnetisMM-30 showed promising synergy despite cytopenias and updates to combination BsAb targeting in RedirecTT-1 demonstrated major activity in difficult to treat extramedullary myeloma (EMM). First-in-human inMMyCAR data showcased the forefront of engineered immune strategies, by introducing an in vivo CAR-T product as a proof-of-concept platform, with tremendous potential to streamline the access to therapy. Collectively, these studies signal a shift toward earlier and adaptive immunotherapy in all phases of MM disease, while underscoring the importance of infection mitigation and long-term safety evaluation.
