The European Commission (EC) has granted conditional marketing authorization for Libtayo (cemiplimab) for the treatment of adults with metastatic or locally advanced cutaneous squamous cell carcinoma (CSCC) who are not candidates for curative surgery or curative radiation.
Libtayo is a fully-human monoclonal antibody targeting the immune checkpoint receptor PD-1 (programmed cell death protein-1) and is the only treatment approved in advanced CSCC in the European Union (EU).
Libtayo is being jointly developed by Sanofi and Regeneron under a global collaboration agreement.
In addition to the EU, Libtayo is also approved in the US, Canada and Brazil for adult patients with metastatic CSCC or locally advanced CSCC who are not candidates for curative surgery or curative radiation. In the US, the generic name for Libtayo is cemiplimab-rwlc, with rwlc as the suffix designated in accordance with Nonproprietary Naming of Biological Products Guidance for Industry issued by the US Food and Drug Administration.
Beyond the ongoing EMPOWER-CSCC-1 trial, Libtayo is also being investigated in adjuvant and neoadjuvant trials in CSCC and in potential registrational trials in non-small cell lung cancer, basal cell carcinoma and cervical cancer. Additional studies include trials in squamous cell carcinoma of the head and neck, melanoma, colorectal cancer, prostate cancer, multiple myeloma, Hodgkin’s lymphoma and non-Hodgkin’s lymphoma. These trials are designed to investigate Libtayo as monotherapy; in combination with conventional treatments like chemotherapy; or in combination with other investigational agents, including vaccines, oncolytic viruses and bispecific antibodies, among others. These potential uses are investigational, and their safety and efficacy have not been evaluated by any regulatory authority.
