The present invention is directed to combination therapies for treating cell proliferative disorders associated with methylthioadenosine phosphorylase (MTAP) deficient cells in a mammal. The combination therapies selectively kill MTAP-deficient cells by administering an inhibitor of de novo inosinate synthesis and administering an anti-toxicity agent, wherein the inhibitors of de novo inosinate synthesis are inhibitors of glycinamide ribonucleotide formyltransferase (“GARFT”) and/or aminoinidazolecarboximide ribonucleotide formyltransferase (“AICARFT”), and the anti-toxicity agent is an MTAP substrate (e.g. methylthioadenosine or “MTA”), a precursor of MTA, an analog of an MTA precursor or a prodrug of an MTAP substrate.
本发明涉及用于治疗哺乳动物中与甲基硫腺苷磷酸化酶(MTAP)缺乏细胞相关的细胞增殖性疾病的联合疗法。该联合疗法通过给予新生核苷酸合成抑制剂和给予抗毒性剂,选择性地杀死MTAP缺乏细胞,其中,新生核苷酸合成抑制剂是甘氨酰核苷酸甲酰转移酶(“GARFT”)和/或氨基咪唑羧酰核苷酸甲酰转移酶(“AICARFT”)的抑制剂,抗毒性剂是MTAP底物(例如,甲基硫腺苷或“MTA”),MTA的前体,MTA前体的类似物或MTAP底物的前药。
