GSK's B7-H3 ADC delivers first Phase III survival win in relapsed lung cancer

14 September 2026

UK pharma major GSK (LSE: GSK) has set out full survival data for risvutatug rezetecan, its B7-H3 targeted antibody-drug conjugate (ADC), in what it says are the first Phase III results showing a survival gain for the target class in any tumor type. The trial was run in China by partner Hansoh Pharmaceutical Group (HKEX: 3692).

In the ARTEMIS-008 study, presented at the World Conference on Lung Cancer in Seoul, the drug cut the risk of death by 54% against topotecan in patients whose small cell lung cancer (SCLC) had progressed after platinum-based first-line treatment. Median overall survival (OS) was 18.5 months versus 10.3 months for topotecan.
