METHODS FOR CANCER TREATMENT USING A RADIOLABELED ANTI-CD45 IMMUNOGLOBULIN AND ADOPTIVE CELL THERAPIES

摘要

Methods for the treatment of a proliferative disorder include administration of a radiolabeled anti-CD45 antibody in concert with an adoptive cell therapy. The adoptive cell therapy may include administration of cells expressing a chimeric antigen receptor or a T-cell receptor (CAR/TCR). The radiolabeled anti-CD45 antibody may be administered before administration of the population of cells expressing the CAR/TCR, either alone or in conjunction with standard lymphodepletion agents. The radiolabeled anti-CD45 antibody may be administered after administration of the population of cells expressing the CAR/TCR in preparation for transplantation of autologous stem cells and/or administration of a second effective amount of the populations of cells expressing the CAR/TCR. These methods may improve treatment outcomes for hematological malignancies including solid tumors, and/or may lessen side effects associated with adoptive cell therapies.
