TransThera Sciences Achieves Key Milestone with Phase II Clinical Trial Approval for Innovative Prostate Cancer Therapy
Highlights from the Announcement
- Regulatory Green Light: TransThera Sciences (Nanjing), Inc. has obtained approval from China’s National Medical Products Administration (NMPA) to begin a Phase II clinical trial for its core product, Tinengotinib (TT-00420), in combination with a novel hormone therapy (NHT) for metastatic castration-resistant prostate cancer (mCRPC) patients who have progressed after prior treatments. The approval was granted on 25 May 2026.
- Unique Mechanism of Action: Tinengotinib is the world’s first and only investigational drug that simultaneously inhibits the FGFR and JAK pathways. This dual inhibition approach has demonstrated clinical evidence in treating mCRPC, a patient population with significant unmet needs.
- Strategic Combination Therapy: The trial will assess the safety, efficacy, and pharmacokinetics of Tinengotinib combined with NHT. While NHT is the current standard of care, resistance typically develops over time. Tinengotinib is designed to address this resistance by targeting the pathways that drive the transformation of androgen-sensitive cancer cells into neuroendocrine cancer cells, which are more drug-resistant.
- Potential to Reverse Drug Resistance: By inhibiting both FGFR and JAK pathways, Tinengotinib could reverse the cell state transformation (lineage reprogramming), restoring cancer cells’ sensitivity to androgens and re-sensitizing them to NHT treatment.
- Positive Clinical Signals: Tinengotinib monotherapy has already shown encouraging antitumor efficacy in heavily pre-treated mCRPC patients. Importantly, the drug received Fast Track Designation from the U.S. FDA for this indication in June 2025, highlighting its potential and regulatory momentum.
Implications for Shareholders and Potential Price Sensitivity
- Major Pipeline Progress: The NMPA’s approval to commence Phase II trials in China is a substantial development for the company, potentially accelerating the path to commercialization and expanding the market for Tinengotinib.
- First-Mover Advantage: As the only drug in clinical development with this dual-targeted mechanism for mCRPC, Tinengotinib positions TransThera as a front-runner in addressing drug resistance for advanced prostate cancer.
- Regulatory Recognition: Fast Track Designation by the U.S. FDA adds international validation to Tinengotinib’s promise and could attract further investor interest or strategic partnerships.
- Caution: Shareholders should note the warning that there is no assurance of successful product development or commercialization. Clinical development risks remain.
About the Study and Next Steps
The approved Phase II trial is an open-label, multicenter study focused on patients with mCRPC who have experienced disease progression after prior treatments. The primary objectives are to evaluate safety, efficacy, and pharmacokinetics of the combination therapy. The company’s Board, led by Dr. Frank Wu (Chairman and CEO), sees this as a critical step in advancing its pipeline and reinforcing its leadership in precision oncology.
Board Composition
As of the announcement date, the Board comprises Dr. Frank Wu and Mr. Wu Di as executive directors, Ms. Jia Zhongxin as a non-executive director, and Mr. Li Shu Pai, Ms. Chui Hoi Yam, and Ms. Zheng Zhelan as independent non-executive directors.

天境生物重大進展：Tinengotinib聯合新型內分泌治療獲批中國II期臨床試驗
公告重點
- 監管批准：天境生物（南京）有限公司獲中國國家藥品監督管理局（NMPA）批准，於2026年5月25日開展核心產品Tinengotinib（TT-00420）聯合新型內分泌治療（NHT）治療既往治療後進展的轉移性去勢抵抗性前列腺癌（mCRPC）患者的II期臨床試驗。
- 獨特機制：Tinengotinib是全球首款同時抑制FGFR及JAK通路的在研藥物，並已在mCRPC臨床治療中有相關證據。
- 創新聯合治療：臨床試驗將評估Tinengotinib聯合NHT的安全性、有效性及藥代動力學。NHT雖為現時標準治療，但患者多會產生耐藥。Tinengotinib有望通過針對驅動細胞轉化的通路，克服耐藥難題。
- 有潛力逆轉耐藥性：同時抑制FGFR及JAK通路可逆轉細胞狀態轉化（譜系重編程），令癌細胞重新對雄激素敏感，重獲NHT治療效果。
- 單藥療效良好：Tinengotinib單藥已在多線治療後mCRPC患者中展現鼓舞人的抗腫瘤活性，並於2025年6月獲美國FDA授予快速通道資格（FTD），進一步肯定其潛力。
對股東及股價的潛在影響
- 重大管線進展：NMPA批准開展II期臨床，或有助加快產品商業化步伐，擴大Tinengotinib市場前景。
- 領先優勢：作為唯一進入臨床開發的雙靶點mCRPC藥物，公司有望搶佔耐藥前列腺癌新治療領域先機。
- 國際認可：美國FDA快速通道資格加強產品潛力及監管信心，或吸引更多投資者及合作夥伴關注。
- 風險提示：公司提醒未來產品能否成功開發及上市尚無保證，臨床開發存有風險。
關於研究與未來計劃
此次獲批的II期臨床為多中心、開放標籤研究，針對既往治療後進展的mCRPC患者，重點評估聯合療法的安全性、有效性及藥代動力學。董事會主席兼行政總裁吳豐博士表示，這將進一步鞏固公司精準腫瘤治療領域的地位。
董事會組成
截至公告日，董事會成員包括執行董事吳豐博士、吳迪先生；非執行董事賈中欣女士；獨立非執行董事李恕培先生、徐海欣女士、鄭哲蘭女士。
