Acquired in 2011, the Osny site specializes in the development and production of highly active solid pharmaceutical forms (hormonal and allergens). This 4,000 m² pharmaceutical plant located 36 km northwest of Paris employs around a hundred people*.

This site’s tablet and capsule development and manufacturing capacities are used to manufacture the hormonal and anti-allergenic products Cenexi supplies to the pharmaceutical sector.

The site is also home to a dozen of the 110 experts of Cenexi Services*, the entity supporting formulation activities, analytical and pharmaceutical form developments, industrial transfer, and regulatory support for experimental products or products already on the market to be manufactured on Cenexi sites. They are grouped within the Development Center for solid oral forms specialized in highly active products (allergens and hormones) and complex processes (controlled release, microdosing). This center is composed of a non-GMP area for the manufacture of test batches, a GMP area (white room) for the manufacture of pilot batches and clinical batches and finally an analytical development laboratory.
