What to evaluate for AAV programs
Both Ascend Advanced Therapies and BioReliance (Merck) qualify as AAV CDMOs. When choosing between them for AAV programs, weigh these four dimensions specifically — each carries through to the side-by-side scorecard above.
Platform & scale
Suspension processes scale better than adherent (HEK293) for commercial volumes. Confirm the CDMO's largest validated bioreactor scale and serotype track record.
Capsid quality
Full/empty capsid ratio and aggregate control drive potency and safety. Ask about AUC, anion-exchange separation, and the analytics package for capsid characterization.
Regulatory readiness
For programs heading to BLA, a strong FDA inspection history and EMA/MHRA GMP coverage matter — both are shown above and on each profile.
Capacity & timelines
AAV manufacturing slots can be constrained. Weigh the capacity signal and clinical-program load before committing.
