Theliatinib (HMPL-309) is a novel small molecule, epidermal growth factor receptor tyrosine kinase inhibitor with potential antineoplastic and anti-angiogenesis activities. Theliatinib is being developed as an oral formulation for the treatment of solid tumors like non-small cell lung cancer.
Theliatinib pre-clinical studies were conducted in China. In vitro studies suggest that Theliatinib is a potent EGFR kinase inhibitor with good kinase selectivity and in vivo data demonstrated broad spectrum anti-tumor activity via oral dosing in multiple xerographs such as A-431, Bcap-37 and Fadu. Non-clinical safety studies have indicated that Theliatinib is generally well tolerated in animals.
In November 2012, HMP initiated the first-in-human clinical trials of theliatinib.
