Bispecific anti-CD38/CD28 antibodies for treatment of multiple myeloma

Since CD38 is a protein expressed at high levels in multiple myeloma cells, it is an ideal target for antibody design for treatment. Patent US11905332, which describes two anti-CD38/CD28 bispecific antibodies (bsAb6031 and bsAb7945) with the potential for the treatment of multiple myeloma, was evaluated. The results described in the patent show that the anti-CD38/CD28 bispecific antibodies caused elevated in vitro cytotoxicity in tumor cells through increased proliferation of CD4+ and CD8+ cells, and the release of IFN-γ, IL-2, and TNF-α, as well as efficacy in a mouse model of multiple myeloma. Anti-CD38/CD28 bispecific antibodies have the potential to be used alone or in combination with other antibodies, including anti-BCMA/CD3 antibodies, for the treatment of multiple myeloma.
