Shenzhen Chipscreen Biosciences Co., Ltd. (hereinafter referred to as "Chipscreen Biosciences") and its wholly-owned subsidiary Chengdu Chipscreen Pharmaceutical Ltd., received the "Drug Clinical Trial Approval Notice" approved by the National Medical Products Administration. The company's self-developed original new drug, Chiauranib, combined with PD - (L) 1 monoclonal antibody and standard chemotherapy for the first-line treatment of extensive stage small cell lung cancer, has been approved for phase III clinical trials.

Extensive disease small cell lung cancer (ES-SCLC), as a highly aggressive subtype of lung cancer, has long been a huge challenge in the field of treatment. In recent years, chemo-immunotherapy has greatly improved the survival outcomes of patients with small cell lung cancer. However, compared to other types of tumors, there is still great room for improvement in the long-term survival of patients with small cell lung cancer. Chiauranib has a multi pathway pharmacological mechanism and has unique anti-tumor activity against neuroendocrine tumors such as small cell lung cancer. At the same time, it can produce synergistic effects with immunotherapy and chemotherapy through its dual effects of anti-angiogenesis and immune regulatory activity. On the basis of first-line chemo-immunotherapy, the introduction of the new regimen of Chiauranib is expected to further improve the long-term survival of patients with extensive stage small cell lung cancer, demonstrating enormous clinical treatment potential.

In addition to the approved Phase III clinical trial, the phase III clinical trial of Chiauranib monotherapy for the later-line treatment of small cell lung cancer has been completed and the Pre NDA is currently under communication. The phase III clinical trial of Chiauranib combined with chemotherapy for ovarian cancer, and the phase II clinical trial of single or combined treatment for triple negative breast cancer, soft tissue sarcoma and pancreatic cancer are also being progressed. In terms of overseas clinical trials, the phase Ib/II clinical trial of Chiauranib monotherapy for small cell lung cancer / solid tumor is in progress in the United States.
