“This NMPA approval of fruquintinib in combination with sintilimab represents a significant advancement for patients with advanced endometrial cancer who have long await more effective treatments. It underscores the potential of fruquintinib to be used with other therapeutic agents to improve patient outcomes,” said Dr. Michael Shi, Head of R&D and Chief Medical Officer of HUTCHMED. “It is also a testament to our ongoing efforts to extend the clinical benefit of fruquintinib to a broader patient population. We are eager to make this innovative treatment available to advanced endometrial cancer patients as soon as we can and will continue to explore further opportunities to bring hope to more patients battling cancer.”

Dr. Hui Zhou, Senior Vice President of Innovent, stated: “This approval of sintilimab and fruquintinib combination therapy marks a meaningful advancement in the treatment landscape for advanced endometrial cancer. Together with HUTCHMED, we aim to provide a novel treatment option that improves survival rates and quality of life for patients facing limited treatment options against this aggressive cancer. TYVYT^® (sintilimab injection), as a cornerstone in immuno-therapy, continues to be evaluated in clinical trials in combination with novel modalities. We remain steadfast in our commitment to reinforcing the leadership position of TYVYT^® (sintilimab injection) in immuno-therapy and driving forward treatment solutions through innovation and cooperation.”

In July 2023, the NMPA granted Breakthrough Therapy Designation to the combination of fruquintinib and sintilimab for this potential indication. This designation recognizes the potential of a therapy to address a severe condition with no effective treatment options, and where clinical evidence demonstrates substantial advantages over existing therapies.

A Phase III confirmatory study of the fruquintinib and sintilimab combination in this setting has been planned (NCT06584032).

About Endometrial Cancer

Endometrial cancer originates in the uterus and remains a significant global health challenge. In 2020, approximately 417,000 people were diagnosed with endometrial cancer, resulting in around 97,000 deaths.² Іn China alone, an estimated 82,000 new cases and 17,000 were reported in 2020.³ While early-stage endometrial cancer can often be surgically resected, recurrent and/or metastatic endometrial cancer remains an area of high unmet need with poor outcomes and limited treatment options.^4,5,6

About Fruquintinib

Fruquintinib is a selective oral inhibitor of all three vascular endothelial growth factor (“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

Fruquintinib is approved for marketing for the treatment of patients with metastatic colorectal cancer who have previously received fluoropyrimidine, oxaliplatin and irinotecan-based chemotherapy, and those who have previously received or are not suitable for receiving anti-VEGF therapy or anti-epidermal growth factor receptor (“EGFR”) therapy (RAS wild-type) in China, where it is co-developed and 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.

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. Fruquintinib 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.

The 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 2023,⁷ while results from the FRESCO trial were published in The Journal of the American Medical Association, JAMA.⁸

About Sintilimab

Sintilimab, marketed as TYVYT^® (sintilimab injection) in China, is a PD-1 immunoglobulin G4 monoclonal antibody co-developed by Innovent and Eli Lilly and Company. Sintilimab is a type of immunoglobulin G4 monoclonal antibody, which binds to PD-1 molecules on the surface of T-cells, blocks the PD-1 / PD-Ligand 1 (PD-L1) pathway, and reactivates T-cells to kill cancer cells.⁹

In China, sintilimab has been approved and included in the updated NRDL for seven indications. The updated NRDL reimbursement scope for TYVYT^® (sintilimab injection) includes:

• For the treatment of relapsed or refractory classic Hodgkin’s lymphoma after two lines or later of systemic chemotherapy;

• For the first-line treatment of unresectable locally advanced or metastatic non-squamous non-small cell lung cancer lacking EGFR or ALK driver gene mutations;

• For the treatment of patients with EGFR-mutated locally advanced or metastatic non-squamous non-small cell lung cancer who progressed after EGFR-TKI therapy;

• For the first-line treatment of unresectable locally advanced or metastatic squamous non-small cell lung cancer;

• For the first-line treatment of unresectable or metastatic hepatocellular carcinoma with no prior systematic treatment;

• For the first-line treatment of unresectable locally advanced, recurrent or metastatic esophageal squamous cell carcinoma;

• For the first-line treatment of unresectable locally advanced, recurrent or metastatic gastric or gastroesophageal junction adenocarcinoma.
  

Furthermore, sintilimab’s eighth indication, in combination with fruquintinib for the treatment of patients with advanced endometrial cancer with pMMR tumors that have failed prior systemic therapy and are not candidates for curative surgery or radiation, has been approved by the NMPA in December 2024.

In addition, two clinical studies of sintilimab have met their primary endpoints:

• Phase II study of sintilimab monotherapy as second-line treatment of esophageal squamous cell carcinoma;

• Phase III study of sintilimab monotherapy as second-line treatment for squamous non-small cell lung cancer with disease progression following platinum-based chemotherapy.

Statement: Innovent does not recommend the use of any unapproved drug(s)/indication(s).
