About Savolitinib

Savolitinib is an inhibitor of MET, an enzyme which has been shown to function abnormally in many types of solid tumors.  Chi-Med designed savolitinib to be a potent and highly selective oral inhibitor, which, through chemical structure modification, addresses human metabolite-related renal toxicity, the primary issue that halted development of several other selective MET inhibitors.  In clinical studies to date, involving over 1,000 patients, savolitinib has shown promising signs of clinical efficacy in patients with MET gene alterations in multiple tumor types with an acceptable safety profile.

About Surufatinib

Surufatinib is a novel, oral angio-immuno kinase inhibitor that selectively inhibits the tyrosine kinase activity associated with vascular endothelial growth factor receptor (VEGFR) and fibroblast growth factor receptor (FGFR), which both inhibit angiogenesis, and colony stimulating factor-1 receptor (CSF-1R), which regulates tumor-associated macrophages, promoting the body’s immune response against tumor cells.  Its unique dual mechanism of action may be very suitable for possible combinations with other immunotherapies. 

A New Drug Application (“NDA”) for surufatinib for the treatment of patients with advanced non-pancreatic NET was accepted for review by the China National Medical Products Administration (NMPA) and granted Priority Review status in December 2019.  A second NDA for surufatinib for the treatment of patients with advanced pancreatic NET is being prepared for submission.  We are preparing for regulatory interactions in the U.S., Europe and Japan to confirm clinical development and path to registration.  In the U.S., surufatinib was granted Fast Track Designations for development in pancreatic and non-pancreatic (extra-pancreatic) NET, and Orphan Drug Designation for pancreatic NET.  Additionally, surufatinib is in several late-stage and proof-of-concept trials in China, including in combination with immunotherapies, and proof-of-concept clinical trials in the U.S.

Chi-Med currently retains all rights to surufatinib worldwide.

About Fruquintinib

Fruquintinib is a highly selective and potent oral inhibitor of VEGFR 1/2/3.  VEGFR inhibitors play a pivotal role in blocking tumor angiogenesis.  Fruquintinib was designed to improve kinase selectivity to minimize off-target toxicities, improve tolerability and provide more consistent target coverage.  The generally good tolerability in patients to date, along with fruquintinib’s low potential for drug-drug interaction based on preclinical assessment, suggests that it may be highly suitable for combinations with other anti-cancer therapies.

Fruquintinib was approved for marketing in China by the NMPA in September 2018 and commercially launched by Eli Lilly and Company (“Lilly”) in late November 2018 under the brand name Elunate®, for the treatment of patients with metastatic colorectal cancer (“CRC”).  We also intend to initiate a Phase III registration study for CRC in the U.S., Europe and Japan.  A Phase III registration study is also ongoing in China for the treatment of patients with gastric cancer, in combination with paclitaxel.  Additionally, fruquintinib is in several other proof-of-concept trials in China and the U.S., including in combination with immunotherapies.

Chi-Med retains all rights to fruquintinib outside of China and is partnered with Lilly in China.
