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.
About Savolitinib
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.
