Abstract
There is accumulating evidence of BCMA and GPRC5D loss after treatment with T-cell redirecting therapies in patients with relapsed/refractory multiple myeloma (RRMM).
While complete CD38 loss is not observed upon relapses after treatment with anti-CD38 monoclonal antibodies (mAb), there is downregulation of surface CD38 expression and decreased number and function of NK cells, which renders these patients resistant to retreatment with anti-CD38 mAb.
Here, we provide preclinical evidence that RRMM patients previously exposed to anti-CD38 mAb could benefit from T-cell-based immunotherapy that depend less on CD38 antigen density and NK-cell activity, such as the novel CD38/CD3xCD28 trispecific T-cell engager, SAR442257.
