# Adjuvant Skin Cancer Immunotherapies Health Canada Approves Libtayo for High-Risk CSCC By Mursal Rahman | Published 2026-09-11 | Lifestyle Source: Trend Hunter, https://www.trendhunter.com/trends/adjuvant-skin-cancer-immunotherapies References: [newswire](https://www.newswire.ca/news-releases/libtayo-r-cemiplimab-for-injection-receives-health-canada-approval-for-adjuvant-treatment-of-high-risk-cutaneous-squamous-cell-carcinoma-809797655.html)  Regeneron Canada is expanding adjuvant skin cancer immunotherapies following Health Canada’s approval of Libtayo for adults with [cutaneous squamous cell carcinoma](https://www.trendhunter.com/trends/oncology-skin-database) (CSCC) at high risk of recurrence after surgery and radiation. The fully human monoclonal antibody targets the PD-1 immune checkpoint receptor, helping prevent cancer cells from suppressing T-cell activation. In the phase 3 C-POST trial, Libtayo reduced the risk of disease recurrence or death by 68% compared with placebo after a median follow-up of 24 months. The approval extends immunotherapy into an earlier stage of CSCC care, giving clinicians an additional option after surgery and radiation rather than reserving systemic treatment for advanced disease. For Regeneron, the expanded indication increases the potential patient population for an existing therapy while strengthening Libtayo’s role across multiple cancers. It also demonstrates how established [checkpoint inhibitors](https://www.trendhunter.com/trends/sophia-genetics) can gain additional value through new treatment settings.
