Shenzhen Chipscreen Biosciences Co., Ltd. has received approval from the National Medical Products Administration for a Phase III clinical trial of Chiauranib in combination with a PD-(L)1 monoclonal antibody and standard chemotherapy. This trial will evaluate the efficacy of the combination as a first-line treatment for extensive-stage small cell lung cancer (ES-SCLC).
Addressing Unmet Needs in ES-SCLC
ES-SCLC is an aggressive subtype of lung cancer that presents significant treatment challenges. While chemo-immunotherapy has improved survival outcomes, there remains a need for therapies that can further enhance long-term survival. Chiauranib's multi-pathway pharmacological mechanism offers a potential solution by targeting neuroendocrine tumors and synergizing with both immunotherapy and chemotherapy through its anti-angiogenic and immune-regulatory activities.
Chiauranib's Mechanism of Action
Chiauranib, a novel molecular entity developed by Chipscreen Biosciences, is a selective inhibitor of Aurora B, a key mitotic regulator. It also targets VEGFR to inhibit tumor angiogenesis and blocks CSF1R and DDR1 pathways to reduce immunosuppressive cell infiltration, thereby enhancing the tumor immune microenvironment. This triple-pathway mechanism allows Chiauranib to exert a comprehensive anti-tumor effect.
Ongoing Clinical Trials
In addition to the newly approved Phase III trial, a Phase III clinical trial of Chiauranib monotherapy for later-line treatment of small cell lung cancer has been completed, and pre-NDA communication is underway. Further clinical trials are in progress, evaluating Chiauranib in combination with chemotherapy for ovarian cancer, as well as single or combined treatments for triple-negative breast cancer, soft tissue sarcoma, and pancreatic cancer. An ongoing Phase Ib/II clinical trial in the United States is also assessing Chiauranib monotherapy for small cell lung cancer and solid tumors.
