Libtayo® (cemiplimab) Recommended for EU Approval by the CHMP for Adjuvant Treatment of CSCC with a High Risk of Recurrence After Surgery and Radiation
The positive opinion is supported by results from the global Phase 3 C-POST trial investigating adjuvant Libtayo versus placebo in patients with CSCC at high risk of recurrence following surgery and radiation. In the trial, Libtayo reduced the risk of disease recurrence or death by 68% compared to placebo (hazard ratio [HR]: 0.32; 95% confidence interval [CI]: 0.20-0.51; p<0.0001). Fewer patients treated with Libtayo had locoregional or distant recurrence compared with those who received placebo (4% vs. 17% and 5% vs. 13%, respectively). Detailed data were published in the New England Journal of Medicine (NEJM) in May 2025.
