CSTONE PHARMA-B (02616) surged nearly 7% intraday, and as of press time, it was up 5.22% at HK$6.25, with a turnover of HK$39.03 million.
The catalyst behind the rally is the announcement 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, stated, "Following the EC's initial approval of sugemalimab for first-line treatment of metastatic squamous and non-squamous NSCLC in 2024, this new indication approval comes just one year later. This marks sugemalimab's full coverage from Stage III to IV NSCLC in Europe, offering a new treatment option for a broader patient population. CSTONE PHARMA-B remains committed to enhancing global accessibility to sugemalimab, fulfilling our long-term promise to patients."
