Client stories: what they were looking for in a CDMO

We’ve helped our customers develop and manufacture innovative therapies for more than 20 years.

“The team at BrainEver really valued working with GTP Bioways. They quickly captured our needs and came back with suitable solutions that fit our tight timelines. Their experience in protein production was, without question, a strong asset in moving from academia research into the inital development phases.”

Hubert Mechain, BrainEver


“With GTP Bioways, Osivax found a reliable GMP-compliant formulation and aspetic filling service provider. Their understanding of our needs, commitment to quality and customer-oriented focus were appreciated. They are also our partners for some R&D and analytical activities with relevant and problem-solving scientific discussions”

Imène Turki, Osivax

“We are happy to work with GTP Bioways for our very first clinical trial. This collaboration is a key point in the preparation of our clinical product before its administration to patients. With their brand-new facilities in Toulouse and their aseptic fill and finish operations, GTP Bioways shows all the guarantees requested for our lead anticancer compound ABD-3001 during our first-in-human clinical trial in acute myeloid leukemia upcoming soon. During the set-up of our GMP production, GTP Bioways team has been quite flexible and reactive to our needs “

Ismail Ceylan, Founder and CEO of Advanced Biodesign

“At European Vaccine Initiative, we have found GTP Bioways to be a very reliable partner. I specifically appreciated the intelligence their team put in the process development, going beyond merely executing our instructions.”

Nicolas Havelange, EVI
