Chi-Med Highlights Oral Presentations on Savolitinib Lung Cancer Programs at AACR Annual Meeting

Press Release


London: Thursday, March 28, 2019: Hutchison China MediTech Limited (“Chi-Med”) (AIM/Nasdaq: HCM) will share further data on the savolitinib development programs in lung cancer at the American Association of Cancer Research (AACR) Annual Meeting in Atlanta, Georgia, USA, March 31 to April 3, 2019.

Preliminary efficacy and safety results will be presented from the China Phase II study of savolitinib monotherapy in non-small cell lung cancer (“NSCLC”) patients with MET Exon 14 skipping mutations who have failed prior systemic therapy, or are unable to receive chemotherapy (abstract #CT031, clinicaltrials.gov identifier NCT02897479).

In addition, several abstracts will be presented from the TATTON Phase Ib/II trial of savolitinib in combination with Tagrisso® (osimertinib) in patients with epidermal growth factor receptor (“EGFR”) mutation-positive NSCLC and MET-amplification who have progressed following treatment with an EGFR tyrosine kinase inhibitor (“EGFR-TKI”) (clinicaltrials.gov identifier NCT02143466). One presentation will focus on patients who had progressed on a first- or second-generation EGFR-TKI and had not previously received a third-generation EGFR-TKI (abstract #CT032). Another presentation will focus on patients whose disease further progressed despite prior treatment with a third-generation EGFR-TKI (abstract #CT033). These presentations are complemented by a poster presentation on detection methods for identifying MET-driven EGFR-TKI resistance in the TATTON trial (abstract #4897/20).

TATTON preliminary results were presented at the World Conference on Lung Cancer (WCLC) in Yokohama, Japan, in October 2017.[1] The TATTON trial supports SAVANNAH, an ongoing Phase II clinical trial exploring the combination of savolitinib and Tagrisso® to overcome MET-driven EGFR-TKI resistance following treatment with Tagrisso® (clinicaltrials.gov identifier NCT03778229).

Further details of the presentations are as follows:

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 900 patients, savolitinib has shown promising signs of clinical efficacy in patients with c-MET gene alterations in multiple tumor types 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.

This press release contains forward-looking statements within the meaning of the “safe harbor” provisions of the U.S. Private Securities Litigation Reform Act of 1995. 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 Tagrisso®, Iressa® and Imfinzi® as combination therapeutics with savolitinib, such risks and uncertainties include assumptions regarding the safety, efficacy, supply and continued regulatory approval of Tagrisso®, Iressa® and 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.
