CSTONE PHARMA-B (02616) surged more than 5%, reaching HK$5.94 by the time of writing, with a trading volume of HK$8.23 million. The uptick follows the announcement on November 25 that the European Commission (EC) has approved a new indication for Sugemalimab: as a monotherapy for adult patients with unresectable Stage III non-small cell lung cancer (NSCLC) whose tumor cells express PD-L1 ≥1%, lack EGFR-sensitive mutations or ALK/ROS1 genomic alterations, and have not progressed after platinum-based chemoradiotherapy (CRT).
Dr. Yang Jianxin, CEO, R&D President, and Executive Director of CSTONE PHARMA-B, noted that this approval comes just one year after the EC first greenlit Sugemalimab for first-line treatment of metastatic squamous and non-squamous NSCLC in 2024. The latest approval marks Sugemalimab's expanded coverage in Europe, spanning Stage III to IV NSCLC, offering a new therapeutic option for a broader patient population.
