Submits New Drug Application to CFDA for Fruquintinib in Advanced Colorectal Cancer

– Application accepted by CFDA for technical review by the Center for Drug Evaluation –

– Triggers RMB30.8 million milestone payment from Eli Lilly and Company (“Lilly”) –

Shanghai: Monday, June 12, 2017: Hutchison MediPharma (“HMP”) today announces that the China Food and Drug Administration (“CFDA”) has acknowledged acceptance of the New Drug Application (“NDA”) for fruquintinib for the treatment of patients with advanced colorectal cancer, which triggers a milestone payment of RMB30.8 million (US$4.5 million) from Lilly to HMP.  The NDA is supported by data from the successful FRESCO study, a Phase III pivotal registration trial of fruquintinib in 416 patients with locally advanced or metastatic colorectal cancer (“CRC”) in China, which was highlighted in an oral presentation at the American Society of Clinical Oncology Annual Meeting on June 5, 2017.

About CRC

CRC is the second most common cancer type in China, with about 380,000 new cases per year, according to National Central Cancer Registry of China.  There were approximately 1.5 million new CRC cases globally in 2015 which are expected to increase to approximately 1.7 million new cases per year by 2020, according to Frost & Sullivan.

About Fruquintinib

Fruquintinib is a highly selective small molecule drug candidate that has been shown to inhibit vascular endothelial growth factor receptor (“VEGFR”) 24 hours a day via an oral dose, with lower off-target toxicities compared to other targeted therapies.  Its tolerability, along with its clean drug-drug interaction profile demonstrated to date, may enable rational combination with other cancer therapies such as in our ongoing clinical trials of fruquintinib in combination with chemotherapy and targeted therapy.

At an advanced stage, tumors secrete large amounts of VEGF, a protein ligand, to stimulate formation of excessive vasculature (angiogenesis) around the tumor to provide greater blood flow, oxygen, and nutrients to the tumor.  VEGF and VEGFR play pivotal roles in tumor-related angiogenesis, and fruquintinib inhibits the VEGF/VEGFR pathway.  This represents an important therapeutic strategy in blocking the development of new blood vessels essential for tumors to grow and invade.

Fruquintinib is currently under joint development in China by HMP and its partner Lilly.  HMP and Lilly jointly announced top-line results from the FRESCO CRC trial on March 3, 2017.  In addition, fruquintinib is being studied in China in a Phase III pivotal trial in non-small cell lung cancer (“NSCLC”), known as FALUCA; and a Phase II study using fruquintinib combined with Iressa® (gefitinib) in the first-line setting for patients with advanced or metastatic NSCLC.  Other studies currently being planned, and soon to be initiated, include a Phase III study in gastric cancer in combination with paclitaxel in China, new studies in the United States, and certain exploratory studies in combination with other oncology agents.
