About PRCC in the CALYPSO study
PRCC is a subtype of kidney cancer that is unusually difficult to treat, with low response rates from current treatment options and no treatments approved for this specific indication. The CALYPSO study is an independently sponsored open-label Phase II study of Imfinzi® in combination with several drug candidates in the treatment of renal cell carcinoma in the U.K. and Spain. Several arms of CALYPSO are evaluating the treatment of PRCC and clear cell renal carcinoma (ccRCC) with savolitinib, a highly selective inhibitor of the c-MET receptor tyrosine kinase, both as a monotherapy and in combination with Imfinzi® (durvalumab), AstraZeneca’s anti-programmed death-ligand 1 (“PD-L1”) antibody. CALYPSO enrolls an all-comer PRCC population with planned retrospective molecular profiling. For further details, please refer to clinicaltrials.gov number NCT02819596.
Savolitinib is a potential first-in-class inhibitor of c-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 c-MET inhibitors. In clinical studies to date, involving over 700 patients, savolitinib has shown promising signs of clinical efficacy in patients with c-MET gene alterations in PRCC, NSCLC, colorectal cancer (CRC) and gastric cancer with an acceptable safety profile. Chi-Med is currently testing savolitinib in partnership with AstraZeneca in Phase Ib/II studies, in multiple solid tumor indications, both as a monotherapy and in combinations.

These forward-looking statements reflect Chi-Med’s current expectations regarding future events, including its expectations for the clinical development of savolitinib, plans to initiate clinical studies for savolitinib, its expectations as to whether such studies would meet their primary or secondary endpoints, and its expectations as to the timing of the completion and the release of results from such studies. Forward-looking statements involve risks and uncertainties. Such risks and uncertainties include, among other things, assumptions regarding enrollment rates, timing and availability of subjects meeting a study’s inclusion and exclusion criteria, changes to clinical protocols or regulatory requirements, unexpected adverse events or safety issues, the ability of drug candidate savolitinib to meet the primary or secondary endpoint of a study, to obtain regulatory approval in different jurisdictions and to gain commercial acceptance after obtaining regulatory approval, the potential market of savolitinib for a targeted indication and the sufficiency of funding. In addition, as certain studies rely on the use of Imfinzi® as combination therapeutics with savolitinib, such risks and uncertainties include assumptions regarding the safety, efficacy, supply and continued regulatory approval of Imfinzi®. Existing and prospective investors are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date hereof. For further discussion of these and other risks, see Chi-Med’s filings with the U.S. Securities and Exchange Commission and on AIM.
