Libtayo® (cemiplimab) Neoadjuvant Treatment Demonstrates Encouraging Event-Free Survival in Patients with Resectable Cutaneous Squamous Cell Carcinoma (CSCC)
TARRYTOWN, N.Y., Oct. 21, 2023 (GLOBE NEWSWIRE) -- Regeneron Pharmaceuticals, Inc. (NASDAQ: REGN) today announced the first presentation of key secondary endpoints for an investigational regimen of PD-1 inhibitor Libtayo® (cemiplimab) as a neoadjuvant monotherapy in stage II to IV resectable cutaneous squamous cell carcinoma (CSCC). The results from an international Phase 2 trial were presented in an oral session at the European Society for Medical Oncology (ESMO) Congress 2023 and concurrently published in The Lancet Oncology.
- “Advanced, resectable cutaneous squamous cell carcinoma can lead to reduced patient function and quality of life following the cumulative effects of treatment, typically surgery and radiation.
- “Results from both the single-institution pilot trial and the multi-center Phase 2 trial found neoadjuvant cemiplimab was highly active in patients with resectable cutaneous squamous cell carcinoma.
- These robust responses were durable, translating into event-free survival for the vast majority of patients at one and two years.”
The multicenter, single-arm Phase 2 trial included two parts. - In Part 1, patients (n=79) received Libtayo 350 mg every three weeks for up to four doses, followed by curative-intent surgery.
