Regeneron Libtayo sBLA for Cervical Cancer
FDA has accepted for review a Regeneron Pharmaceuticals supplemental BLA for PD-1 inhibitor Libtayo (cemiplimab-rwlc) to treat patients with recurrent or metastatic cervical cancer whose disease progressed on or after chemotherapy. The user fee review action target date is 1/30/2022.
The submission is based on data from the Phase 3 EMPOWER-Cervical 1 clinical trial that evaluated Libtayo monotherapy versus an investigator’s choice of chemotherapy in patients with recurrent or metastatic cervical cancer who had progressed on platinum-based chemotherapy, according to the company. The primary endpoint for the trial was overall survival.
Regeneron describes Libtayo as a fully human monoclonal antibody targeting the PD-1 immune checkpoint receptor on T-cells. By binding to PD-1, Libtayo has been shown to block cancer cells from using the PD-1 pathway to suppress T-cell activation, it says.
Libtayo is currently approved for treating several types of skin cancer. It is also approved for treating non-small cell lung cancer.
