Sanofi grants Regeneron worldwide exclusive license rights to Libtayo

3 June 2022

French pharma major Sanofi (Euronext SAN) yesterday said it is restructuring its immuno-oncology collaboration with Regeneron Pharmaceuticals (Nasdaq: REGN).

Under the amended and restated license and collaboration agreement, Regeneron will obtain worldwide exclusive license rights to Libtayo (cemiplimab).

The Sanofi and Regeneron global immuno-oncology license and collaboration agreement was originally executed in 2015. Prior to Thursday, the companies had split Libtayo’s worldwide operating profits equally and co-commercialized Libtayo in the USA, with Sanofi solely responsible for commercialization in the rest of the world.
