Chi-Med Plans to Submit Marketing Authorization Application for Surufatinib Following Scientific Advice from EMA’s CHMP

Hong Kong, Shanghai, & Florham Park, NJ: Monday, August 10, 2020: Hutchison China MediTech Limited (“Chi-Med”) (Nasdaq/AIM: HCM) today announces that it received scientific advice from the European Medicines Agency's (“EMA”) Committee for Medicinal Products for Human Use (“CHMP”) for surufatinib for the treatment of patients with advanced neuroendocrine tumors (“NET”).  Based on the CHMP advice, we have concluded that the completed SANET-ep (non-pancreatic NET) and SANET-p (pancreatic NET) studies, along with existing data from surufatinib in U.S. non-pancreatic and pancreatic NET patients, could form the basis to support a marketing authorization application (“MAA”).  Given that no filing issues were identified, the MAA submission is planned for 2021, following submission for the U.S. Food and Drug Administration (“FDA”) new drug application (“NDA”).



About Surufatinib


Surufatinib 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, where there may be synergistic anti-tumor effects.


Chi-Med currently retains all rights to surufatinib worldwide.



About Surufatinib Development


NET in the U.S., Europe and Japan: In the U.S., surufatinib was granted Fast Track Designations for development in pancreatic and non-pancreatic (extra-pancreatic) NET in April 2020, and Orphan Drug Designation for pancreatic NET in November 2019.  A U.S. FDA NDA submission is being prepared, to be followed by a MAA submission to the EMA in Europe.  All such interactions are based on the robust data from the two positive Phase III studies of surufatinib in NET in China, and the ongoing multi-cohort Phase Ib study in the U.S. that began in November 2015 ( identifier: NCT02549937). 


Non-pancreatic NET in China: In November 2019, a NDA for surufatinib for the treatment of patients with advanced non-pancreatic NET was accepted for review by the China National Medical Products Administration (“NMPA”) and granted Priority Review status in December 2019.  The NDA is supported by data from the successful SANET-ep study, a Phase III study of surufatinib in patients with advanced non-pancreatic NET in China for whom there is no effective therapy.  A 198-patient interim analysis was conducted in June 2019, leading the Independent Data Monitoring Committee (“IDMC”) to determine that the study met the pre-defined primary endpoint of progression-free survival (“PFS”) and should be stopped early.  The positive results of this trial were highlighted in an oral presentation at the 2019 European Society for Medical Oncology Congress (“ESMO”) ( identifier: NCT02588170). 


Pancreatic NET 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 NET in China.  Following an interim analysis review conducted in January 2020 by the IDMC that recommended the registrational study be terminated early as the pre-defined primary endpoint of PFS had already been met ( identifier: NCT02589821), we submitted our second NDA to the China NMPA and are now waiting for formal acceptance.  The results of this study will be presented at ESMO 2020.


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) ( identifier NCT03873532).


Immunotherapy combinations: We have entered into collaboration agreements to evaluate the safety, tolerability and efficacy of surufatinib in combination with anti-PD-1 monoclonal antibodies, including with tislelizumab (BGB-A317, developed by BeiGene, Ltd.), Tuoyi® (toripalimab, developed by Shanghai Junshi Biosciences Co. Ltd.) and Tyvyt® (sintilimab, developed by Innovent Biologics, Inc.), which are approved in China.
