Based on dialogue with the Japanese Pharmaceuticals and Medical Devices Agency (PMDA), it was agreed that the surufatinib Japanese new drug application ("NDA") for the treatment of advanced NETs include results from a pivotal study to be conducted in Japan, to complement the registration data package supporting the NDA to the U.S. Food and Drug Administration ("FDA") (accepted for review in June 2021) and the Marketing Authorization Application ("MAA") to the European Medicines Agency ("EMA") (validated in July 2021). The basis for the NDA and the MAA includes data from a U.S. Phase I/II study, as well as the completed Phase III SANET-ep and SANET-p studies used to support marketing authorization in China in advanced NETs, where surufatinib is currently marketed under the brand name SULANDA.

This Japan study is a two-stage, open label study of surufatinib where approximately 34 patients are expected to be recruited. In Part 1 of the study, the safety and tolerability of surufatinib 300mg once daily after 28 days of treatment will be assessed in patients with relapsed/refractory non-hematological malignancies; pharmacokinetics ("PK") and anti-tumor activity of surufatinib are secondary endpoints. In Part 2 of the study, efficacy will be assessed in patients with locally advanced or metastatic NETs; the primary outcome measure is objective response rate (ORR). The secondary outcome measures include disease control rate (DCR), progression free survival ("PFS"), duration of response (DoR), safety, and PK.

Surufatinib is the third potential new medicine discovered by HUTCHMED to enter into clinical development in Japan. A global Phase III registration study for fruquintinib, known as the FRESCO-2 study, is ongoing in patients with refractory metastatic colorectal cancer and is expected to enroll over 680 patients from over 150 sites in 14 countries, including Japan. A global single-arm, open-label study, known as the SAVANNAH study, is ongoing for savolitinib (partnered with AstraZeneca PLC) in combination with TAGRISSO in non-small cell lung cancer patients whose disease progressed following TAGRISSO due to MET amplification or overexpression.

About NETs
NETs 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. NETs are typically classified as pancreatic NET ("pNET") or extra-pancreatic (non-pancreatic) NET ("epNET").

According to Frost & Sullivan, there were 19,000 newly diagnosed cases of NET in the U.S. in 2020. Rates across the European Union (E.U.) appear largely similar to the U.S. This is supported by an analysis of global epidemiologic trends, which also show growth in the incidence of NETs worldwide.[i] Importantly, NETs are associated with a relatively long duration of survival compared to other tumors. As a result, there were approximately 140,000 estimated patients living with NET in France, Germany, Italy, Spain, and the United Kingdom in 2020.[ii] In Japan, approximately 6,700 people were diagnosed with gastro-entero-pancreatic neuroendocrine neoplasms in 2016.[iii]

About Surufatinib
Surufatinib is a novel, oral angio-immuno kinase inhibitor that selectively inhibits the tyrosine kinase activity associated with vascular endothelial growth factor receptors (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.

HUTCHMED currently retains all rights to surufatinib worldwide.

About Surufatinib Development
epNETs in China: On December 29, 2020, surufatinib was granted drug registration approval by the National Medical Products Administration of China ("NMPA") for the treatment of epNET. Surufatinib is marketed in China under the brand name SULANDA. The approval was based on results from the SANET-ep study, a Phase III trial (clinicaltrials.gov identifier: NCT02588170) in patients with advanced epNETs conducted in China. The study met the pre-defined primary endpoint of PFS at a preplanned interim analysis, and was published in The Lancet Oncology[iv]. Median PFS was significantly longer for patients treated with surufatinib at 9.2 months, compared to 3.8 months for patients in the placebo group (HR 0.334; 95% CI: 0.223-0.499; p<0.0001). Surufatinib had an acceptable safety profile, with the most common treatment related adverse events of grade 3 or worse being hypertension (36% of surufatinib patients vs. 13% of placebo patients), proteinuria (19% vs. 0%) and anemia (5% vs. 3%).

pNETs in China: On June 16, 2021, surufatinib was granted drug registration approval by the NMPA for the treatment of pNET. The approval was based on results from the SANET-p study, a Phase III trial (clinicaltrials.gov identifier: NCT02589821) in patients with advanced pNET in China. The pre-defined primary endpoint of PFS was met at a preplanned interim analysis and was published in The Lancet Oncology[v], demonstrating that surufatinib reduces the risk of disease progression or death by 51% in patients, with a median PFS of 10.9 months compared to 3.7 months on placebo (HR 0.491; 95% CI: 0.391-0.755; p=0.0011). The safety profile of surufatinib was manageable and consistent with observations in prior studies.

Immunotherapy combinations: HUTCHMED 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), TUOYI (toripalimab) and TYVYT (sintilimab), which are approved as monotherapies in China.

NETs in the U.S. and Europe: A FDA NDA submission was accepted in June 2021, followed by a MAA submission to the EMA validated in July 2021. The basis to support these filings includes the completed SANET-ep and SANET-p studies, along with existing data from surufatinib in U.S. epNET and pNET patients (clinicaltrials.gov identifier: NCT02549937). In the U.S., surufatinib was granted Fast Track Designations for development in pNET and epNET in April 2020, and Orphan Drug Designation for pNET in November 2019.

HUTCHMED has initiated an Expanded Access Protocol (EAP) in the U.S. to ensure patients with NET with limited therapeutic options have access to this treatment. Regulatory clearance of this protocol has been granted by the FDA and this program is open for site activation (clinicaltrials.gov identifier: NCT04814732).

Professor Shen Lin, the lead principal investigator of the study and Vice President of Peking University Hospital and Cancer Institute, said: "There is a large unmet clinical need for patients with NEC, many of whom have a bleak prognosis. Following the encouraging preliminary data from the Phase II trial, we are excited to move into the next stage of development in combining the novel, oral angio-immuno kinase inhibitor surufatinib with the anti-PD-1 antibody toripalimab. We look forward to further testing the synergistic anti-tumor effects of this combination that could benefit NEC patients who have limited treatment options."

At the American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) 2021 Annual Meeting, encouraging preliminary data from the Phase II trial were disclosed for the surufatinib and toripalimab combination1. For the 20 patients in the NEC cohort as of December 31, 2020, who received an average of 5 cycles of treatments and are efficacy evaluable, objective response rate ("ORR") was 20% and disease control rate ("DCR") was 70%. Median progression-free survival ("PFS") was 3.9 months (95% CI: 1.3 – not reached). Grade 3 or higher treatment-related adverse events occurred in 33% of patients. Treatment related adverse events ("TRAEs") were manageable, with surufatinib or toripalimab interruption occurred in 6 (28.6%) and 4 (19%) patients respectively. There were neither serious adverse events ("AEs") nor AEs inducing treatment discontinuations or deaths. Updated data will be presented at the Chinese Society of Clinical Oncology (CSCO) 2021 Annual Meeting in late September.

The SURTORI-01 Phase III study is a randomized, controlled, open-label, multi-center study where approximately 200 patients are expected to be enrolled. For the study group, all patients will receive study treatment in 21-day cycle and the treatment will continue until there is a progression of disease, death, intolerable toxicity, or the end of study treatment (as other criteria specified in the protocol are met), whichever occurs first. The primary outcome measure is OS. The secondary outcome measures include PFS, ORR, duration of response (DoR), and DCR. Additional details may be found at clinicaltrials.gov, using identifier NCT05015621.

HUTCHMED is the sponsor of SURTORI-01 and responsible for all clinical and regulatory execution of the Phase III study. HUTCHMED and Junshi Biosciences are jointly funding the study.

Surufatinib is marketed in China under the brand name SULANDA for treating advanced neuroendocrine tumors ("NETs").

About NEC

Neuroendocrine neoplasms ("NEN") occur almost everywhere in the body but are most common in the gastrointestinal tract, pancreas, and lungs. NEC is one of the two common phenotypes of NEN. NECs are poorly differentiated, highly proliferating NENs, while NETs are well-differentiated, low-proliferating NENs. NECs are aggressive, fast-growing neoplasms that usually fail to express hormones or produce hormonal syndromes, and are not associated with hereditary tumor diseases.2

About Surufatinib

Surufatinib is a novel, oral angio-immuno kinase inhibitor that selectively inhibits the tyrosine kinase activity associated with vascular endothelial growth factor receptors (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.

About Toripalimab

Toripalimab is the first domestic anti-PD-1 monoclonal antibody to obtain marketing approval in China. So far, more than thirty company-sponsored clinical studies covering more than fifteen indications have been conducted globally including in China and the United States. On December 17, 2018, toripalimab was granted conditional approval from the NMPA for the second-line treatment of patients with unresectable or metastatic melanoma. In December 2020, toripalimab was successfully included in the updated National Reimbursement Drug List. In February 2021, toripalimab received NMPA’s conditional approval for the treatment of patients with recurrent or metastatic nasopharyngeal carcinoma ("NPC") after failure of at least two lines of prior systemic therapy. In April 2021, toripalimab received NMPA’s conditional approval for the treatment of patients with locally advanced or metastatic urothelial carcinoma who failed platinum-containing chemotherapy or progressed within 12 months of neoadjuvant or adjuvant platinum-containing chemotherapy. In addition, toripalimab has been included in the Guidelines of the Chinese Society of Clinical Oncology (CSCO) for the Diagnosis and Treatment of Melanoma, Head and Neck Tumors, Urothelial Carcinoma and other indications.

In February 2021, the supplemental new drug application (the "sNDA") of toripalimab in combination with cisplatin and gemcitabine as the first-line treatment for patients with locally recurrent or metastatic NPC was accepted for review by the NMPA. In March 2021, toripalimab received Breakthrough Therapy Designation for the first-line treatment of advanced mucosal melanoma by the NMPA. In July 2021, the sNDA for toripalimab in combination with platinum-containing chemotherapy as the first-line treatment for patients with locally advanced or metastatic esophageal squamous cell carcinoma was accepted for review by the NMPA.

In terms of international development, the first toripalimab Biological License Application (BLA) has been submitted to the FDA for the treatment of recurrent or metastatic NPC. The FDA has granted two Breakthrough Therapy designations for toripalimab in combination with chemotherapy for the first line treatment of recurrent or metastatic NPC and also for toripalimab monotherapy in second or third line treatment of recurrent or metastatic NPC.
