CHMP recommendation is primarily based on the results of GEMSTONE-302, a multi-center, randomized, double-blind, Phase 3 clinical trial. Sugemalimab in combination with chemotherapy significantly improved PFS and OS compared to placebo in combination with chemotherapy in previously untreated stage IV NSCLC patients. The study results have been published in The Lancet Oncology and Nature Cancer and reported in oral sessions at various international academic conferences.

Sugemalimab is an anti-PD-L1 monoclonal antibody developed by CStone, which has been approved in China for five indications, including stage III and IV NSCLC, extranodal NK/T-cell lymphoma, esophageal squamous cell carcinoma, and gastric cancer. Additionally, the U.K. Medicines and Healthcare products Regulatory Agency (MHRA) is currently reviewing the marketing authorization application for sugemalimab combined with chemotherapy as a first-line treatment for metastatic NSCLC. The company is also in communications with regulatory authorities such as the EMA, MHRA, and U.S. Food and Drug Administration (FDA) regarding additional indications for sugemalimab and is actively seeking development and commercialization partnerships in other countries and regions worldwide.
