PARIS and TARRYTOWN, N.Y., June 4, 2018 /PRNewswire/ -- The New England Journal of Medicine (NEJM) today published pivotal data from two trials evaluating cemiplimab in advanced cutaneous squamous cell carcinoma (CSCC). The results were also presented at the 2018 American Society of Clinical Oncology (ASCO) Annual Meeting. Advanced CSCC, the deadliest nonmelanoma skin cancer, encompasses both patients with metastatic CSCC and those with locally advanced CSCC who are not candidates for surgery; there is currently no approved treatment for these patients. Cemiplimab is an investigational human monoclonal antibody targeting the immune checkpoint PD-1 (programmed cell death protein 1).
"The strong results seen with cemiplimab are noteworthy given that advanced CSCC is a very serious condition that currently has no approved treatments once surgery is no longer an option," said Michael R. Migden, M.D., co-lead author and Associate Professor in the Departments of Dermatology and Head and Neck Surgery at The University of Texas MD Anderson Cancer Center. "Advanced CSCC tumors were shown to be responsive to cemiplimab in both metastatic and locally advanced patients, with the results being clinically meaningful and consistent between the Phase 1 and Phase 2 trials."
Pivotal CSCC trials represent largest prospective data set in this advanced cancer
Data published in NEJM and/or presented at ASCO, and confirmed by independent central review, include:
These findings formed part of the data set used for regulatory applications for cemiplimab as a potential treatment for advanced CSCC. These applications were accepted earlier this year for priority review by the U.S. Food and Drug Administration (FDA) and review by the European Medicines Agency (EMA). The FDA target action date is October 28, 2018, and the EMA review process is expected to be complete by the first half of 2019. Regulatory applications in additional countries are also being considered for submission later in 2018. There are currently no FDA- or EMA-approved treatments for patients with metastatic CSCC or patients with locally advanced CSCC who are not candidates for surgery.
Cemiplimab is being jointly developed by Sanofi and Regeneron under a global collaboration agreement. In addition to CSCC, cemiplimab is also being investigated in potentially pivotal/pivotal trials in non-small cell lung cancer, basal cell carcinoma and cervical cancer alongside exploratory trials in squamous cell carcinoma of the head and neck, melanoma, colorectal cancer, prostate cancer, multiple myeloma, Hodgkin lymphoma and non-Hodgkin lymphoma.
Cemiplimab is currently under clinical development, and its safety and efficacy have not been evaluated by any regulatory authority.
CSCC is the second most common type of skin cancer in the U.S., accounting for approximately 20 percent of all skin cancers and with the number of newly diagnosed cases expected to rise annually. Although CSCC has a good prognosis when caught early, the cancer can prove especially difficult to treat effectively when it is advanced, and patients can experience reduced quality of life due to the impact of the disease as it progresses. Advanced CSCC is the deadliest non-melanoma skin cancer. While estimates vary, sources suggest that between 4,000 to 8,000 people in the U.S. die annually of advanced CSCC.
