From the early 2000s, Mak concentrated his efforts on the emerging field of cancer metabolism. Mak, Lewis C. Cantley, and Craig B. Thompson together founded Agios Pharmaceuticals, a biotech pharmaceutical company whose sole purpose is to discover methods of targeting cancer metabolism. The trio have contributed immensely in a few years to what was originally a forgotten paradigm. The discovery of the involvement of particular enzymes such as PKM2, mutated IDH as well as novel oncometabolites such as 2-hydroxyglutarate in cancer development have once again brought cancer metabolism back to the forefront of cancer biology. On August 1, Agios announced that the FDA had approved their lead compound, IDHIFA®, for the treatment of acute myeloid leukemia. IDHIFA® targets a mutant form of Isocitrate dehydrogenase 2 and is the first drug specifically targeting cancer metabolism to be used for cancer treatment.
