Naobios provides bioprocess development and contract manufacturing services for viral vaccines and viral vectors. The company was acquired by Clean Biologics on March 1st, 2019 and now supports clients for process development and the manufacture of preclinical and clinical batches.

Facilities and capabilities

Naobios is located in Saint Herblain (France) and is composed of independent biomanufacturing and R&D areas. The biomanufacturing and QC areas operate according to European GMP. The company has the capacity and expertise to handle complete projects for process development and GMP manufacturing of cell banks, virus seeds and clinical batches of Drug Substance. Extensive use is made of Single-use-Systems (SUS) to improve efficiency, minimize cleaning and avoid cross contamination. The production clean rooms can accommodate Single-use Bioreactors up to 250 litres, together with an homogenizer, TFF systems, Single-use filtration and chromatography systems for DSP operations.


The QC unit handles environmental monitoring and in-house testing for raw materials, media, buffers and intermediates as well as Drug Substance.
