Banniere ADC 728x90 V3

Novasep has been a leading contract service provider in the ADC arena for more than 10 years. Today we propose a fully integrated supply chain for the cGMP manufacturing of ADCs, including bioconjugation, payload, linker & mAbs.

Our commitment to ADCs is underlined by the recent €11M investment in a stand-alone bioconjugation unit at our Le Mans site in France. This state-of-the-art facility is now fully operational.

For the 3rd consecutive year, Novasep has been nominated as a finalist for Best Contract Manufacturing (CMO) Provider at the 2017 World ADC Awards. The company was also rewarded at the CMO Leadership Awards 2017 with recognition in 6 core categories (capabilities, compatibility, development, expertise, quality, reliability) and 7 specialty categories (accessible senior management, cultural fit, innovation, on-time, reputation, state-of-the-art, strength of science).

Production of ADC payload and linker

We offer a full range of integrated CMO services including process development, cGMP clinical lots and validation, as well as commercial cGMP manufacturing.

With 25 years’ experience in the synthesis and HPLC purification of cytotoxics at industrial scale, the team is particularly well trained and skilled to support our customers for their ADC payload and linker production projects. 

ADC Equipment


Novasep team has worked on all of the main payload platforms (e.g. maytansins, auristatins, pyrrolo-benzodiazepines), and can support your projects at any scale of production.

Due to their high toxicity, payload manufacturing at industrial scale requires specifically designed facilities for contained production activities. Novasep has put in place detailed practices for the controlled and safe manufacture of highly potent active pharmaceutical ingredients.

Our dedicated manufacturing facility for the commercial cGMP production of payloads with an Occupational Exposure Level (OEL) of 0.03 µg.m-3.8h-1 and lower was commissioned in 2014.

The Le Mans site was successfully inspected by the FDA in May 2016.
