Bioconjugate process development

With our unique combination of knowledge and experience, we provide end-to-end support for your project, covering every stage from initial process development to GMP manufacturing of high-quality bioconjugates.

GTP Bioways CDMO - Antibody drug conjugate development

Expert CDMO for manufacturing of bioconjugates & ADC

Bioconjugation involves linking molecules together with at least one of the reactants being a biomolecule, often an antibody, protein, or oligonucleotide. The successful and safe manufacturing of these complex drugs requires an experienced team and dedicated facilities when cytotoxic compounds are involved.

Our team’s proficiency extends to supporting the development, optimisation, and scale-up of a variety of bioconjugation processes.

Offering both mammalian and microbial manufacturing for the production of the biologics intermediates, GTP Bioways can manufacture a variety of bioconjugates, including but not limited to antibody-drug conjugates (ADC), antibody fragment-drug conjugates (ScFvDC), antibody-oligonucleotide conjugates (AOC) and other protein- and peptide-drug conjugates.




Mammalian or microbial manufacturing capabilities

Our expertise in both mammalian and microbial manufacturing allows us to provide solutions for the manufacturing of a wide range of bioconjugates.

Extended expertise in bioconjugation

For over a decade, our teams have been developing conjugation processes involving a variety of biomolecules (antibodies, proteins, peptides, antibody fragments, oligonucleotides…) and cytotoxic payloads.

Comprehensive process development services for bioconjugates and ADC

Our seasoned team offers a comprehensive range of process development services for antibody-drug conjugates (ADCs) and other drug conjugates:

    • Our team is well-versed in using various conjugation technologies, including, but not limited to, maleimide-, NHS-ester-, oxime-, enzyme-assisted- and glycosylation-based-conjugations
    • Our team has extensive expertise in site-specific conjugation technologies (DAR 2 to DAR 8) and in conjugating diverse linker-payload combinations, including cytotoxins like auristatin, maytansine, camptothecin, and anthracyclines, as well as non-toxic functionalities such as PEG, oligonucleotides, kinase inhibitors, and immunomodulators.
    • Additionally, our downstream process development team has developed a strong expertise in developing purification processes for a wide range of bioconjugates, employing purification methods like UF/DF and column chromatography (IEX, HIC, protein A).
