P1 | "Tal-DP exhibits a deep, long-term impact on efficacy through complementary mechanisms of action and may be especially beneficial in pts with prior BsAb exposure, who typically have unfavorable BL immune profiles. Ongoing analyses of tec-DP from MajesTEC-2 (NCT04722146) will be presented."

Teclistamab continues to demonstrate deep and durable responses, including in pts who switch to less frequent dosing. The safety profile of teclistamab remains consistent with that of BCMA-targeted bispecific therapies, with a notable decrease in new onset of severe infections with time.

Preliminary data from the MajesTEC-2 trial ( NCT04722146 ) demonstrated that teclistamab, daratumumab, and lenalidomide combination ( teclistamab + DR ) is tolerable, with promising efficacy in patients with relapsed/refractory multiple myeloma and NDMM. The phase 3 MajesTEC ‑ 7 ( NCT05552222 ) study will compare teclistamab + DR vs DR + dexamethasone in patients with NDMM who are ineligible/not intended for autologous stem cell transplant as initial treatment... These results from the first safety run-in of MajesTEC-7 demonstrate a manageable safety profile with early efficacy of teclistamab + DR in NDMM. Two additional safety run-ins are ongoing investigating teclistamab( less frequent dosing ) + DR and talquetamab + DR

Prior therapy-mediated loss of plasma cell BCMA expression before teclistamab treatment, measured by immunohistochemistry, was observed in 3 patients, none of whom responded to teclistamab, and one of whom also did not respond to ciltacabtagene autoleucel. Whole exome sequencing of tumor DNA from one patient revealed biallelic loss of TNFRSF17 following treatment with belantamab mafodotin. Low-to-undetectable peripheral blood soluble BCMA levels correlated with the absence of BCMA expression by bone marrow plasma cells. Thus, although rare, loss of BCMA expression following TNFRSF17 gene deletions can occur following any BCMA-directed therapy and prevents response to subsequent anti-BCMA-directed treatments, underscoring the importance of verifying the presence of a target antigen.

Primary resistance is characterized by a low T-cell/MM cell-ratio and Treg-driven immunosuppression, while reduced T-cell fitness due to continuous BsAb-mediated T-cell activation may contribute to development of acquired resistance.

These findings illustrate the importance of the contribution of the immune landscape to T-cell redirection therapy response. This trial was registered at www.ClinicalTrials.gov, NCT03145181/NCT04557098.
