Antibodies specific for CD38 and uses thereof

CD38 is also expressed in a variety of hematological malignancies, including multiple myeloma. In the present invention, the inventors obtained a new antibody against CD38 that can be used to produce bispecific antibodies and CAR T cell populations. In particular, the inventors reported the development of Bi38-3, a new bispecific T cell engager that targets CD38 on MM cells and forms cytotoxic T cells through CD3ε. Bi38-3 lacks the Fc region of natural mAbs, which contributes to the resistance process, but triggers T cell proliferation, cytokine release, and lysis of CD38-positive MM cells in vitro. Similarly, Bi38-3 induces autologous T cells to eliminate tumor plasma cells isolated from MM patients at diagnosis and relapse. The cytotoxicity triggered by Bi38-3 is limited to cells expressing high levels of CD38 and maintains the integrity of T, B, and NK lymphocytes in vitro. Importantly, Bi38-3 rapidly reduced tumor cells in the MM1.S xenograft mouse model of human MM. In summary, the results show that the antibody of the present invention is an effective agent for specifically eliminating CD38-positive malignant cells without significantly affecting CD38-low-expressing cells, and is a promising new immunotherapy tool for treating malignant blood diseases, especially multiple myeloma.
