LONDON, UK I June 14, 2019 I Hutchison China MediTech Limited (“Chi-Med”) (AIM/Nasdaq: HCM) today announces that the independent Data Monitoring Committee (“IDMC”) of the Phase III pivotal study of surufatinib in advanced neuroendocrine tumors – extra-pancreatic (“SANET-ep”) has completed a planned interim analysis. The IDMC determined that the study has already met the pre-defined primary endpoint of progression free survival (“PFS”) and as a result the study will be stopped.
Chi-Med will now arrange for a pre-New Drug Application (“NDA”) meeting with the China National Medical Products Administration (NMPA) to discuss the preparation of the NDA for surufatinib for this indication. We intend to submit the results of the SANET-ep study for presentation at an upcoming scientific conference.
About SANET-ep
SANET-ep is a Phase III study in China of surufatinib in patients with low- or intermediate-grade advanced extra-pancreatic neuroendocrine tumors patients for whom there is no effective therapy. In this study, patients are randomized at a 2:1 ratio to receive either 300 mg of surufatinib orally daily or placebo, on a 28-day treatment cycle. The primary endpoint of the study is to evaluate the PFS, with secondary endpoints including objective response rate (ORR), disease control rate (DCR), time to response (TTR), duration of response (DoR), overall survival (OS), safety, and tolerability. Additional details may be found at clinicaltrials.gov, using identifier NCT02588170.
About Neuroendocrine Tumors
Neuroendocrine tumors form in cells that interact with the nervous system or in glands that produce hormones. They can originate in various parts of the body, most often in the gut or the lungs and can be benign or malignant. Neuroendocrine tumors are typically classified as pancreatic neuroendocrine tumors or other neuroendocrine tumors. Approved targeted therapies include Sutent® and Afinitor® for pancreatic neuroendocrine tumors, or well-differentiated, non-functional gastrointestinal or lung neuroendocrine tumors.
According to Frost and Sullivan, there were 19,000 newly diagnosed cases of neuroendocrine tumors in the U.S. in 2018. Importantly, neuroendocrine tumors are associated with a relatively long duration of survival compared to other tumors. As a result, there were approximately 141,000 estimated patients living with neuroendocrine tumors in the U.S. in 2018 of which over 90%, or approximately 132,000, were non-pancreatic neuroendocrine tumor patients.
In China there were approximately 67,600 newly diagnosed neuroendocrine patients in 2018 and, considering the U.S. incidence to prevalence ratio, potentially as many as 490,000 patients living with the disease.
About Surufatinib
Surufatinib (previously known as HMPL-012 or sulfatinib) is a novel, oral angio-immuno kinase inhibitor that selectively inhibits the tyrosine kinase activity associated with vascular endothelial growth factor receptor (VEGFR) and fibroblast growth factor receptor (FGFR), which both inhibit angiogenesis, and colony stimulating factor-1 receptor (CSF-1R), which regulates tumor-associated macrophages, promoting the body’s immune response against tumor cells. Its unique dual mechanism of action may be very suitable for possible combinations with other immunotherapies. Surufatinib is in proof-of-concept clinical trials in the U.S. and several proof-of-concept and late-stage clinical trials in China.
We currently retain all rights to surufatinib worldwide.
Pancreatic neuroendocrine tumors in China: In 2016, we initiated the SANET-p study, which is a pivotal Phase III study in patients with low- or intermediate-grade, advanced pancreatic neuroendocrine tumors in China. The primary endpoint is PFS. We expect an interim analysis in late 2019 and enrollment to complete in 2020 (clinicaltrials.gov identifier: NCT02589821).
Pancreatic neuroendocrine tumors in the U.S. and Europe: The encouraging data from the Phase II study of surufatinib in pancreatic neuroendocrine tumors in China (clinicaltrials.gov identifier: NCT02267967), and the ongoing Phase Ib/II study in the U.S., have led us to decide to proceed with planning a registration study in pancreatic neuroendocrine tumors patients.
Biliary tract cancer in China: In March 2019, we initiated a Phase IIb/III study comparing surufatinib with capecitabine in patients with advanced biliary tract cancer whose disease progressed on first-line chemotherapy. The primary endpoint is overall survival (OS) (clinicaltrials.gov identifier NCT03873532).
Immunotherapy combinations: In November 2018, we entered into collaboration agreements to evaluate the safety, tolerability and efficacy of surufatinib in combination with checkpoint inhibitors. This included a global collaboration to evaluate the combination of surufatinib with Tuoyi®, a PD-1 monoclonal antibody approved in China in late 2018 by Shanghai Junshi Biosciences Co. Ltd.
