DS320 may stop the growth of tumor cells by blocking some of the enzymes needed for c growth. Immunotherapy with monocional antibodies, such as ipilimumab, may help the body's immune system attack the cancer, and may infecterg with the ability of tumor cells to grow and spread. Sting B63201 and ipilinumab may help te contral the diseaseDS3201 is an orally available potent and selective inhibitor of EZH1 and EZH2 (th histone lysine methyltransferases enhancer of zeste homolog 1 and 2) (both wild-type and mutated forms) with IC50s in nanomolar concentrationsIpilimumab is an IV infusion monocional antibody that works to activate the immu system by targeting CTLA-4, a protein receptor that downregulates the immune system
