LONDON, UK I March 02, 2016 I Hutchison China MediTech Limited (“Chi-Med”) (AIM: HCM) today announces that Hutchison MediPharma Limited (“HMP”), its drug R&D subsidiary, has initiated an open-label Phase II clinical trial to evaluate the efficacy and safety of sulfatinib (HMPL-012) in patients with locally advanced or metastatic radioactive iodine-refractory differentiated thyroid cancer (“DTC”) or medullary thyroid cancer (“MTC”) in China. The first patient was dosed on March 1, 2016.

HMP plans to enroll approximately 50 DTC and MTC patients into this study, with approximately 25 patients in each tumor type. The primary objective is to evaluate the objective response rate (“ORR”), while secondary and exploratory objectives include the evaluation of safety and tolerability, other efficacy parameters, pharmacokinetics, and tumor biomarkers. The study employs a two-stage design in which 15 subjects of each tumor type will be enrolled in the first stage. An additional 10 subjects in each tumor type will be enrolled after efficacy assessment in the second stage. Additional details about this study may be found at clinicaltrials.gov, using identifier NCT02614495.

Sulfatinib is an oral drug candidate that selectively inhibits the tyrosine kinase activity associated with the vascular endothelial growth factor receptor (“VEGFR”) and fibroblast growth receptor (“FGFR”), two tyrosine kinase receptors associated with angiogenesis and tumor growth. HMP believes that sulfatinib’s VEGFR/FGFR1 inhibition profile has strong potential in second-line thyroid cancer patients, particularly in China where there are few safe and effective treatment options for this patient population.

In addition to the thyroid cancer trial, HMP is conducting or in the process of initiating four clinical trials in neuroendocrine tumors (“NETs”).

About thyroid cancer

Thyroid cancer is the most commonly diagnosed endocrine malignancy. Global incidence rates have increased sharply and continuously over the past few decades. According to the National Cancer Institute (“NCI”), in the U.S., incidence rates of thyroid cancer have increased by an average of 5% each year over the last 10 years. Further, an article published in Cancer Research estimates that it could become the fourth most commonly diagnosed cancer by 2030. In China, thyroid cancer is now the fastest growing tumor type and accounted for approximately 2% of all new cancer cases reported in 2015, according to the National Central Cancer Registry of China (“NCCRC”).

This rise in incidence has been most dramatic in women. According to through the NCCRC, 67,900 new cases were reported in women compared to just 22,200 in men in China in 2015. Thyroid cancer now represents the most frequently diagnosed cancer in Chinese women under the age of 30. In the U.S., incidence rates of thyroid cancer are three-fold higher in women than in men, according to the NCI.
