Hong Kong, Shanghai & Florham Park, NJ - Friday, November 22, 2024: HUTCHMED (China) Limited ("HUTCHMED") (Nasdaq/AIM:HCM; HKEX:13) today announces that it will receive a milestone payment following the pricing approval and launch of FRUZAQLA^® (fruquintinib) 1mg/5mg capsules in Japan by its partner Takeda (TSE:4502/NYSE:TAK) for patients with previously treated metastatic colorectal cancer ("CRC"). This follows approval for the manufacturing and marketing of FRUZAQLA^® by the Japanese Ministry of Health, Labour and Welfare.

FRUZAQLA^® is the first novel oral targeted therapy in Japan to be approved for metastatic CRC, regardless of biomarker status, in over a decade. FRUZAQLA^® is indicated for the treatment of advanced or recurrent colorectal cancer that is neither curable nor resectable, and that has progressed after chemotherapy. CRC is the most prevalent type of cancer in Japan, with an estimated 161,000 new cases and 54,000 deaths in 2023, according to statistics from the National Cancer Center.[1]

On the launch of FRUZAQLA^® in Japan by Takeda, Dr Weiguo Su, Chief Executive Officer and Chief Scientific Officer of HUTCHMED, said: "The launch of FRUZAQLA^® in Japan highlights the continued progress of our partnership with Takeda across the globe. Takeda is well positioned to build on more than a decade of leadership in the treatment of metastatic CRC in Japan and bring a differentiated treatment option in FRUZAQLA^® to patients."

The launch of FRUZAQLA^® in Japan follows its approval in September 2024, primarily based on results from the Phase III FRESCO-2 trial conducted in the US, Europe, Japan and Australia. Data from FRESCO-2 were published in The Lancet in June 2023. Takeda has the exclusive worldwide license to further develop, commercialize, and manufacture fruquintinib outside of mainland China, Hong Kong and Macau, and markets under the FRUZAQLA^® brand name. It received approval in the US in November 2023, in the EU in June 2024, in Switzerland in August 2024, in Canada, Japan and the United Kingdom in September 2024 and in Argentina, Australia and Singapore in October 2024. Regulatory applications are progressing in many other jurisdictions.

About CRC

CRC is a cancer that starts in either the colon or rectum. According to the International Agency for Research on Cancer/World Health Organization, CRC is the third most prevalent cancer worldwide, associated with more than 1.9 million new cases and 900,000 deaths in 2022. In Japan, CRC was the most common cancer, with an estimated 146,000 new cases and 60,000 deaths, in 2022. In Europe, CRC was the second most common cancer in 2022, with approximately 538,000 new cases and 248,000 deaths.[2]^,[3] In the US, it is estimated that 153,000 patients will be diagnosed with CRC and 53,000 deaths from the disease will occur in 2024.[4] 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.[5]^,[6]^,[7]^,[8]^,[9]

About Fruquintinib

Fruquintinib is a selective oral inhibitor of all three VEGF receptors (VEGFR-1, -2 and -3). VEGFR inhibitors play a pivotal role in inhibiting tumor angiogenesis. Fruquintinib was designed to have enhanced selectivity that limits off-target kinase activity, allowing for drug exposure that achieves sustained target inhibition and flexibility for potential use as part of a combination therapy.

About Fruquintinib Approvals

Global regulatory submissions are based on data from two large, randomized, controlled Phase III trials, the global, multi-regional FRESCO-2 trial and the FRESCO trial conducted in China, showing consistent benefit among a total of 734 patients treated with fruquintinib. Safety profiles were consistent across trials. Results from the FRESCO-2 trial were published in The Lancet in June 2023,[10] while results from the FRESCO trial were published in The Journal of the American Medical Association, JAMA.[11]

In mainland China, Hong Kong and Macau, fruquintinib is co-marketed by HUTCHMED and Eli Lilly and Company under the brand name ELUNATE^®. It was included in the China National Reimbursement Drug List (NRDL) in January 2020. Since its launch in China, over 100,000 patients with colorectal cancer have been treated with fruquintinib.

JAPAN IMPORTANT SAFETY INFORMATION

Please consult the FRUZAQLA (fruquintinib) Japan package insert (J-PI) before prescribing.

WARNING: FRUZAQLA should be administered only to patients for whom the use of FRUZAQLA is considered appropriate under the supervision of a physician with sufficient knowledge of and experience in cancer chemotherapy at a medical institution where adequate emergency care can be provided. Prior to treatment initiation, the efficacy and risks should be fully explained to the patient and/or his/her family and informed consent should be obtained; Severe gastrointestinal hemorrhage, including fatal cases, has been reported. Patients should be carefully monitored, and if any abnormalities are observed, administration of FRUZAQLA should be withheld and appropriate measures should be taken. If severe hemorrhage occurs, FRUZAQLA should not be re-administered; Gastrointestinal perforation has been reported with some fatal cases. Patients should be carefully monitored, and if any abnormalities are observed, administration of FRUZAQLA should be withheld and appropriate measures should be taken. If gastrointestinal perforation occurs, FRUZAQLA should not be re-administered.

CONTRAINDICATIONS: Patients with a history of hypersensitivity to any of the ingredients of FRUZAQLA.

IMPORTANT PRECAUTIONS: Hypertension, including hypertensive crisis, may occur. Blood pressure should be measured prior to the initiation of FRUZAQLA treatment and periodically during this treatment; Proteinuria may occur. Urinary protein should be monitored prior to the initiation of FRUZAQLA treatment and periodically during this treatment; If a surgical procedure is to be performed, patients are recommended to withhold FRUZAQLA before the surgery because wound healing may be delayed. Treatment resumption after the surgical procedure should be determined depending on the patient's condition upon confirmation of adequate wound healing.

PRECAUTIONS CONCERNING PATIENTS WITH SPECIFIC BACKGROUNDS: Patients with hyper-ten-sion: Hypertension may worsen; Patients with bleeding diathesis or abnormal coagulation system: Hemorrhagic events may occur; Patients with hemorrhage such as gastrointestinal hemorrhage: Hemorrhage may be enhanced; Patients with a complication of intra-abdominal inflammation in the gastrointestinal tract, etc.: Gastrointestinal perforation may occur; Patients with current or a history of thromboembolism: Transient ischaemic attack, thrombotic microangiopathy, pulmonary embolism, portal vein thrombosis, deep vein thrombosis, etc. may occur; Patients with severe hepatic impairment (Child-Pugh Class C): Since FRUZAQLA is metabolized mainly in the liver, blood concentrations may be increased.
