Presentations of Fruquintinib Phase I Clinical Data and Volitinib Preclinical Data

at the 2013 AACR Annual Meeting

London: Monday, 8 April 2013: Chi-Med today announces that data from the recently completed Phase I clinical trial of Fruquintinib (HMPL-013) and from preclinical studies of Volitinib (HMPL-504), two of the novel small molecule targeted anti-cancer drugs of Hutchison MediPharma Limited ("HMP"), its majority owned R&D company, are being presented at the 2013 American Association for Cancer Research ("AACR") Annual Meeting held in Washington, DC, USA from 6 to 10 April 2013. Presentations on Volitinib are prepared jointly with HMP's collaboration partner AstraZeneca PLC.

AACR is the world's first and largest professional organisation dedicated to advancing cancer research and its mission to prevent and cure cancer. AACR membership includes more than 34,000 laboratory, translational and clinical researchers; population scientists; other health care professionals; and cancer advocates residing in more than 90 countries. AACR marshals the full spectrum of expertise of the cancer community to accelerate progress in the prevention, biology, diagnosis and treatment of cancer by annually convening more than 20 conferences and educational workshops, the largest of which is the AACR Annual Meeting with more than 17,000 attendees.

One presentation will report on the final results of the Fruquintinib Phase I study, which demonstrated favourable clinical safety profile, pharmacokinetic properties and preliminary clinical efficacy. Additionally, three presentations relating to the pharmacokinetics and efficacy of Volitinib in preclinical models are being presented.

The presentations are as follows:

·; Phase I study of safety and pharmacokinetics of Fruquintinib, a selective inhibitor of VEGF receptor -1, -2, and -3 tyrosine kinases in patients with advanced solid tumours

·; Preclinical disposition and pharmacokinetics of Volitinib, a novel selective c-Met inhibitor

·; Synergistic effect of c-Met inhibitor Volitinib in combination with EGFR inhibitor Gefitinib on EGFR-TKI resistant NSCLC model HCC827C4R harbouring acquired Met gene amplification

·; Volitinib (HMPL-504), a novel, selective and potent c-Met inhibitor, is efficacious in primary tumour models of c-Met-driven gastric cancer

Notes to Editors

About VEGF/VEGFR Inhibitors and Fruquintinib

At an advanced stage, tumours secrete large amounts of vascular endothelial growth factor ("VEGF"), a protein, to stimulate formation of excessive vasculature (angiogenesis) around the tumour in order to provide greater blood flow, oxygen, and nutrients to the tumour. Vascular endothelial growth factor receptor ("VEGFR") inhibitors stop the growth of blood vessels around the tumour and thereby starve the tumour of the nutrients it needs to grow rapidly.

Fruquintinib (HMPL-013) is a novel small molecule compound that is highly selective in inhibiting certain VEGF receptors, namely VEGFR1, VEGFR2, and VEGFR3, and consequently has an attractive anti-tumour profile. Fruquintinib has shown highly potent inhibitory effects on multiple human tumour xenografts, including some refractory tumours such as pancreatic cancer and melanoma and anti-tumour and anti-angiogenic effect compares favourably to approved VEGF drugs.

About the c-Met Signal pathway and Volitinib

The c-Met (also known as HGFR) signalling pathway has specific roles particularly in normal mammalian growth and development. However, this pathway has been shown to function abnormally in a range of different cancers. Volitinib is a potent and highly selective c-Met inhibitor, which has been demonstrated to inhibit the growth of tumours in a series of pre-clinical disease models, especially for those tumours with aberrant c-Met signalling such as gene amplification or c-Met over-expression. In addition these biomarkers provide the potential to explore patient selection strategies in later stage clinical trials.
