Biotechnological active ingredient production at the company Merz Group Services

Cleaning validation

For Merz Pharmaceuticals, Testo Industrial Services took over the structuring and processing of the cleaning validation activities within a tight schedule. Complex cleaning processes were developed and implemented especially for this purpose.

Merz Pharmaceuticals is an innovative pharmaceutical company with a focus on the research and marketing of drugs for the treatment of neurological and psychiatric diseases. The site in Dessau-Roßlau is used for the production of a parenteral drug containing a highly active biological agent.

The aim of this project was the holistic handling of the cleaning validation including all development and optimisation activities of the cleaning process in the field of active ingredient production. Throughout the production process, various plant parts, tools and equipment come into contact with the highly active protein, which necessitated cleaning validation adapted to the process requirements. In the further course of the project, the service life validation was connected.
