Chimeric antigen receptor T-cell therapy, or CAR T, has made a big impact on the treatment of certain blood cancers, allowing patients with relapsed/refractory disease to live longer, healthier lives. But in clinical study, the cellular therapy has not been as successful for patients with solid tumors, due in part to the lack of tumor targets not expressed in vital tissues. In a new study published in Molecular Cancer Therapeutics, a journal of the American Association for Cancer Research, Moffitt Cancer Center researchers share the identification of a new potential target for CAR T cells called OR2H1 that they have demonstrated inhibits growth in lung and ovarian tumors.
