Takeda and HUTCHMED Announce New Drug Application (NDA) for Fruquintinib for Treatment of Previously Treated Metastatic Colorectal Cancer Granted Priority Review

− Prescription Drug User Fee Act (PDUFA) Target Action Date Set for November 30, 2023

− NDA Includes Results From the Phase 3 FRESCO-2 and FRESCO Clinical Trials

Takeda (TSE:4502/NYSE:TAK) and HUTCHMED (China) Limited (Nasdaq/AIM:HCM, HKEX:13) (HUTCHMED) today announced that the U.S. Food and Drug Administration (FDA) has granted priority review of the New Drug Application (NDA) for fruquintinib, a highly selective and potent inhibitor of vascular endothelial growth factor receptors (VEGFR) -1, -2 and -3 for the treatment of adult patients with previously treated metastatic colorectal cancer (CRC). If approved, fruquintinib will be the first and only highly selective inhibitor of all three VEGF receptors approved in the U.S. for previously treated metastatic CRC.^1,2 The Prescription Drug User Fee Act (PDUFA) goal date assigned by the FDA for this NDA is November 30, 2023.

“We are confident that fruquintinib has the potential to transform the treatment landscape for those living with previously treated metastatic colorectal cancer, as demonstrated by its strong clinical profile,” said Awny Farajallah, M.D., head of Global Medical Affairs Oncology at Takeda. “There are significant needs for patients with this disease in the U.S., and we believe fruquintinib has the potential to address these needs regardless of patients’ biomarker status. We look forward to continuing conversations with the FDA with the goal to make this therapy available to patients as soon as possible.”

The NDA for fruquintinib includes results from the Phase 3 FRESCO-2 trial along with data from the Phase 3 FRESCO trial conducted in China. FRESCO-2 is a global Phase 3 multi-regional clinical trial (MRCT) conducted in the U.S., Europe, Japan and Australia investigating fruquintinib plus best supportive care (BSC) vs placebo plus BSC in patients with previously treated metastatic CRC. The FRESCO-2 trial met its primary and key secondary endpoints, showing a significant and clinically meaningful improvement in overall survival (OS) and progression-free survival (PFS), respectively. Fruquintinib has been generally well tolerated in patients to date.

“The clinical benefit of fruquintinib has been confirmed in multiple ways, from global clinical studies to commercialization in China. We are pleased to have Takeda as our partner furthering development and commercialization of fruquintinib outside of China,” said Dr. Michael Shi, Head of R&D and Chief Medical Officer, HUTCHMED. “Today’s acceptance marks a significant advancement towards the goal of providing patients with previously treated metastatic colorectal cancer a much-needed therapeutic option, given the limited treatment options currently available to patients. This also supports our ongoing vision to design and develop differentiated molecules that help patients with high unmet needs globally.”

Fruquintinib is currently approved in China under the brand name ELUNATE^®. Approval in China was based on the results of the FRESCO study, a Phase 3 pivotal registration trial of fruquintinib in 416 patients with metastatic CRC in China, published in The Journal of the American Medical Association, JAMA, in June 2018 (NCT02314819).³ In March 2023, HUTCHMED and Takeda closed an exclusive licensing agreement to further the global development, commercialization and manufacture of fruquintinib outside of China.

About Fruquintinib

Fruquintinib is a highly selective and potent oral inhibitor of VEGFR -1, -2 and -3. VEGFR inhibitors play a pivotal role in blocking tumor angiogenesis. Fruquintinib was designed to improve kinase selectivity with the intention of minimizing off-target toxicities, improving tolerability and providing more consistent target coverage. Fruquintinib has been generally well tolerated in patients to date and is being investigated in combinations with other anti-cancer therapies.

About FRESCO-2

The FRESCO-2 study is a multi-regional clinical trial conducted in the U.S., Europe, Japan and Australia investigating fruquintinib plus BSC vs placebo plus BSC in patients with previously treated metastatic CRC. As previously disclosed, the 691-patient study met its primary endpoint of OS in patients with metastatic CRC who had progressed on standard chemotherapy and relevant biologic agents and who had progressed on, or were intolerant to, TAS-102 and/or regorafenib. In addition to OS, a statistically significant improvement in PFS, a key secondary endpoint, was observed. Fruquintinib has been generally well tolerated in patients to date. Summary results were initially presented at the European Society for Medical Oncology (ESMO) Congress in September 2022.⁴ Additional details of the study may be found at clinicaltrials.gov, using identifier NCT04322539.

About CRC

CRC is a cancer that starts in either the colon or rectum. According to the International Agency for Research on Cancer, CRC is the third most prevalent cancer worldwide, associated with 935,000 deaths in 2020.⁵ In the U.S., it is estimated that 153,000 patients will be diagnosed with CRC and 53,000 deaths from the disease will occur in 2023.⁶ In Europe, CRC was the second most common cancer in 2020 with approximately 520,000 new cases and 245,000 deaths. In Japan, CRC was the most common cancer with an estimated 148,000 new cases and 60,000 deaths in 2020.⁵ Although early-stage CRC can be surgically resected, metastatic CRC remains an area of high unmet need with poor outcomes and limited treatment options. Some patients with metastatic CRC may benefit from personalized therapeutic strategies based on molecular characteristics; however, most patients have tumors that do not harbor actionable mutations.^7,8,9,10,11
