Cemiplimab is a programmed cell death protein 1 (PD-1) antibody formulated with Regeneron’s VelocImmune technology that is designed to generate optimised fully human antibodies.

The drug is being developed by Regeneron under a global collaboration agreement with Sanofi.

Regeneron Clinical Sciences vice-president Israel Lowy said: “Regeneron continues to expand and advance our immuno-oncology programme by studying multiple combination therapies in order to fully explore the scientific possibilities in this relatively new field.

“We’re eager to investigate the impact of adding cemiplimab with the goal of further enabling the body’s immune system to attack the cancer.”

“Early clinical results with ISA101 in HPV16-positive indications have been promising, and we’re eager to investigate the impact of adding cemiplimab with the goal of further enabling the body’s immune system to attack the cancer.”
