What to evaluate for Biologics programs
Both Ajinomoto Bio-Pharma Services and Merck KGaA / MilliporeSigma (CDMO) qualify as Biologics CDMOs. When choosing between them for Biologics programs, weigh these four dimensions specifically — each carries through to the side-by-side scorecard above.
Scale & bioreactor fit
Match validated bioreactor scale (from a few hundred litres clinical to 2,000L+ commercial) and single-use vs stainless to your dose and indication. Confirm titer expectations for your construct.
Cell line & process development
Ask whether the CDMO offers its own expression platform/cell line or works from yours, and how process development and tech transfer are handled.
Regulatory track record
Biologics programs heading to BLA/MAA need a strong commercial-scale inspection history. Cross-check FDA 483s, warning letters, and EMA/MHRA GMP coverage — all shown above.
Drug substance to drug product
Confirm whether the CDMO covers fill-finish and formulation in-house or coordinates a separate site, which affects timelines and comparability.
