GTP Bioways CDMO - Antibody drug conjugate development

Accelerate your clinical programme with an expert microbial CDMO

GTP Bioways offers comprehensive CDMO services from strain development to cGMP production of drug substance and drug product.

Our microbial cGMP production facility has been designed to provide maximum flexibility and is perfectly suited to supply clinical batches. We can handle a variety of microbial processes using various strains (E. coli, P. pastoris…) to produce a large panel of proteins for a variety of therapeutic applications.

With our in-house analytical QC capabilities and our seasoned QA team, we ensure consistent, high-quality services.

Best-in-class bioproduction experts

Our teams have gained a unique and recognised expertise in microbial manufacturing, drawn from over 150 processes developed
for a large panel of recombinant proteins such as antibody fragments, cytokines, enzymes, fusion proteins and growth factors.

Their vivid scientific interest in protein science combined with a problem-solving mindset makes us
the best partner to work through any challenge.

Cell line Development process

Cutting-edge microbial GMP production facility

Based on a hybrid design with both stainless steel and single-use equipment, our microbial production facility, allows us to handle a wide range of processes based on various expression strategies (cytoplasmic expression – soluble proteins or inclusion bodies, periplasmic expression or secreted into the media).


  • Our fermentation capacities range up to 350L.
  • To cope with the intrinsic requirements of each production process, our suites include versatile recovery equipment and extraction techniques including batch and continuous centrifuges, HPH with temperature control, a large range of chromatography columns and TFF systems from 0.5 to 15 m².

Exclusive aseptic filling line for microbial drug product

With in-house filling capacities of up to 10 000 units per batch, GTP Bioways is ideally sized to deliver your drug product in vials or pre-filled syringes.

In combining a disposable isolator with automation for filling and stoppering, our exclusive line provides greater efficiency and flexibility, allowing us to shorten timelines for drug product supply.
