May 7, 2020 ,Shanghai, China - Haihe Biopharma, a company focusing on the discovery, development and commercialization of innovative anti-tumor drugs, announced that the company has recently obtained the IND approval from the US Food and Drug Administration (FDA) for its isocitrate dehydrogenase-1 (IDH1) inhibitor HH2301 developed by the company. It is intended to be used to treat solid tumors with IDH1 mutations including Advanced cholangiocarcinoma, chondrosarcoma and glioma.

Abnormal metabolism is one of the ten major characteristics of malignant tumors. Targeting tumor metabolism has become a new anti-tumor strategy with great potential. Isocitrate dehydrogenase (IDH) is a rate-limiting enzyme in the tricarboxylic acid cycle (TCA), and one of the most common metabolic enzymes mutated in human tumors. Mutant isocitrate dehydrogenase 1 (mIDH1) can catalyze α-ketoglutarate (α-KG) to produce (R)-2-hydroxyglutarate (2-HG). As a recognized cancer metabolite, 2-HG can participate in the regulation of many important cell processes through different mechanisms and promote tumor occurrence and malignancy. IDH1 mutations occur widely in many tumors such as cholangiocarcinoma, chondrosarcoma, glioma, and acute myeloid leukemia (AML). More and more studies have confirmed that mIDH1 inhibitors have good therapeutic prospects and safety for the aforementioned tumors. Currently, two IDH inhibitors have been approved by the US Food and Drug Administration (FDA) for the treatment of acute myeloid leukemia with IDH1 or IDH2 mutations, but no such target inhibitor has been approved for the treatment of solid tumors with IDH1 mutations.

HH2301 refers to a new, potent and selective mIDH1 inhibitor jointly developed by Haihe Biopharma and Shanghai Institute of Meteria Medica. Systematic non-clinical studies have shown that the compound has excellent anti-tumor activity in vivo and in vitro, has good pharmacokinetic properties and safety in all tested species. In a variety of solid tumor xenograft models (PDX models) derived from patients with IDH1 mutations, HH2301 exhibits significant anti-tumor activity and has a good prospects for clinical application and development.
