Innovent Biologics Achieves NMPA Approval for TYVYT® (Sintilimab) + ELUNATE® (Fruquintinib) Combination in Advanced Renal Cell Carcinoma
Key Highlights
- Regulatory Approval: The National Medical Products Administration (NMPA) of China has granted approval for the combination therapy of TYVYT® (sintilimab injection) and ELUNATE® (fruquintinib) for the treatment of patients with locally advanced or metastatic renal cell carcinoma (RCC) who have failed prior VEGFR-TKI therapy and have not received PD-1/PD-L1 inhibitor therapy in the first-line setting.
- Milestone for Innovent Biologics: This marks the 10th approved indication for TYVYT® (sintilimab), further strengthening the company’s oncology portfolio and market position in China.
- Potential Share Price Catalyst: Regulatory approvals for new indications, especially in large oncology markets like China, are typically considered highly price-sensitive and can drive share price appreciation due to anticipated revenue growth and expanded addressable patient populations.
Details of the Approval and Supporting Clinical Data
The approval is based on positive results from the FRUSICA-2 Phase III registration study, a randomized, open-label, active-controlled clinical trial. The study compared the combination of sintilimab and fruquintinib against monotherapy with axitinib or everolimus in the second-line treatment of Chinese patients with advanced or metastatic RCC.
- Primary Endpoint Met:
- Median Progression-Free Survival (PFS): 22.2 months with sintilimab + fruquintinib vs. 6.9 months with control arm (HR 0.373, p<0.0001).
- Objective Response Rate (ORR): 60.5% vs. 24.3% (Odds Ratio 4.622, p<0.0001).
- Median Duration of Response (DoR): 23.7 months vs. 11.3 months.
- Overall survival data are still maturing (~20% maturity at cutoff).
- Efficacy benefits seen across all risk groups (IMDC criteria).
- Safety profile consistent with known profiles of individual agents.
- Study Details: Results were presented at the 2025 European Society for Medical Oncology (ESMO) Congress, with a data cutoff of February 17, 2025 and median follow-up of 16.6 months.
Market and Product Overview
- Renal Cell Carcinoma Epidemiology: In 2022, there were approximately 435,000 new kidney cancer cases worldwide, with 74,000 cases in China. RCC accounts for about 90% of kidney tumors.
- Sintilimab (TYVYT®): A PD-1 monoclonal antibody co-developed by Innovent and Eli Lilly, approved in 10 indications in China, acting as a cornerstone immunotherapy in the company’s portfolio.
- Fruquintinib (ELUNATE®): A highly selective oral inhibitor of VEGFR-1, -2, and -3, developed by HUTCHMED and Eli Lilly. Fruquintinib is approved in China for metastatic colorectal cancer and conditionally approved (with TYVYT®) for advanced endometrial cancer. Outside China, Takeda holds worldwide rights and markets it as FRUZAQLA®, with approvals in the US, Europe, Japan, and other territories.
Strategic and Financial Implications for Investors
- Expanded Oncology Franchise: The approval solidifies Innovent’s leadership in the immuno-oncology combination space and provides a new revenue stream from RCC, a major cancer indication in China.
- Broader Addressable Population: The new label expands access to the combination for patients who have failed VEGFR-TKI therapy and have not received PD-1/PD-L1 inhibitors, addressing an area of high unmet need.
- Potential for Further Indications: The company emphasizes ongoing commitment to clinical value optimization and further expansion of TYVYT® and fruquintinib into new indications.
- Shareholder Value: Regulatory milestones of this magnitude are typically seen as catalysts for share price re-rating due to the expected increase in product uptake, enhanced competitive positioning, and long-term revenue growth.

信達生物自主公告：TYVYT® 聯合 ELUNATE® 治療晚期腎細胞癌獲中國NMPA批准
重點摘要
- 監管批准：中國國家藥品監督管理局（NMPA）批准 TYVYT®（信迪利單抗注射液）聯合 ELUNATE®（呋喹替尼）用於治療既往接受 VEGFR-TKI 治療失敗、且一線未用過 PD-1/PD-L1 抑制劑的局部晚期或轉移性腎細胞癌患者。
- 重大里程碑：這是 TYVYT®（信迪利單抗）第 10 個已獲批適應症，進一步鞏固公司在中國腫瘤市場的領導地位。
- 潛在股價催化劑：新適應症獲批通常被視為高度敏感、能夠推動股價的消息，因為預計將帶來收入增長和擴大潛在患者人群。
批准詳情及臨床數據
本次批准基於 FRUSICA-2 Ⅲ期註冊臨床試驗的陽性結果。這項隨機、開放標籤、陽性對照試驗，評估了信迪利單抗+呋喹替尼與阿昔替尼或依維莫司單藥二線治療中國晚期或轉移性腎細胞癌患者的療效和安全性。
- 主要終點達標：
- 中位無進展生存期（PFS）：信迪利單抗+呋喹替尼組為 22.2 個月，對照組為 6.9 個月（HR 0.373，p<0.0001）。
