Discover Grünenthal


Aachen, Germany, November 27, 2014. Grünenthal announced the termination of the license agreement with Actavis for the development and commercialization of Cebranopadol, a novel analgesic for the treatment of chronic pain.

Grünenthal continues the clinical program as planned

Actavis’ subsidiary Forest Laboratories Ireland Limited and Grünenthal GmbH had entered into a license agreement on Cebranopadol in December 2010. This agreement included the co-development and commercialization of Cebranopadol (GRT6005), with exclusive rights for Actavis in the United States and Canada, while Grünenthal held the rights in Europe and the rest of the world.

Grünenthal continues the development program as planned. The termination of the license agreement does not have any impact on the enrollment status of patients who are currently participating in the ongoing clinical trials in Europe and the US.

“We will work with Actavis to fully transition the development activities under the license agreement”, said Klaus-Dieter Langner, PhD, Grünenthal Chief Scientific Officer. “We will continue the development of Cebranopadol to define the best direction for this innovative compound.”
