MISSISSAUGA, ON, March 25, 2022 /CNW Telbec/ - Today sanofi-aventis Canada Inc. (Sanofi) announced the approval of Libtayo® (cemiplimab) for the treatment of adult patients with cervical cancer who have progressed on or after prior platinum-based chemotherapy and who require additional systemic therapy to treat recurrent or metastatic disease. The approval is based on the Phase 3 EMPOWER-Cervical 1 Study of Cemiplimab in Adults With Cervical Cancer (NCT03257267). The trial, which was the largest-ever randomized clinical trial in advanced cervical cancer, included patients with recurrent or metastatic cervical cancer whose histology was either squamous cell carcinoma or adenocarcinoma. Participants were randomized to receive either cemiplimab or the investigator's choice of chemotherapy. The primary endpoint for the trial was overall survivali.

"While rates of cervical cancer in Canada are thankfully decliningii, due in large part to the effectiveness of the HPV vaccine in preventing cervical pre-cancers from formingiii, Canada still sees 1400 women diagnosed with this disease every yeariv and who need treatment options. We're proud to have brought Libtayo to approval for the women who are diagnosed with recurrent or metastatic cervical cancer, and the healthcare professionals who treat them."
With today's announcement, Libtayo is now approved as an immunotherapy option for four advanced cancers:
Cervical cancer is a type of cancer that occurs in the cells of the cervix, which is the lower part of the uterus that connects to the vagina. The human papilloma virus (HPV), which is a sexually transmitted infection, is implicated in most cases of cervical cancer, though the factors that lead an infection with HPV to become cancerous are unknownvi. While cervical cancer is highly preventable and treatable, and Canada has set the goal of eliminating cervical cancer by 2040iii, in 2021 an estimated 1450 Canadians were diagnosed with the disease, and 380 died as a result of itvii.
Libtayo is a fully human monoclonal antibody targeting the immune checkpoint receptor PD-1 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.
The extensive clinical program for Libtayo is focused on difficult-to-treat cancers. Current clinical development programs include Libtayo in combination with chemotherapy for advanced NSCLC irrespective of PD-L1 expression and Libtayo in combination with either conventional or novel therapeutic approaches for other solid tumors and blood cancers. These potential uses are investigational, and their safety and efficacy have not been evaluated by any regulatory authority.
Libtayo is being jointly developed by Sanofi and Regeneron under a global collaboration agreement.
