Research has progressed furthest in cancer, where scientists have shown that PD-1 can shut down immune responses when it is activated by certain types of tumor cells. Last month, the U.S. Food and Drug Administration approved human testing of an experimental antibody designed to reverse the shutdown and permit the immune system to resume fighting cancer cells. The experimental drug is being developed by Medarex Inc., of Princeton, N.J., and Ono Pharmaceutical Co., of Japan.
