Best Exosome / Extracellular Vesicle CDMOs by Signal Score
Exosome and extracellular vesicle (EV) CDMOs manufacture next-generation delivery vehicles for RNA, proteins, and small molecules. As an emerging modality, the field is still standardizing cell-source, isolation, and potency methods.
Choosing an exosome CDMO turns on cell-source and culture scale, isolation method (TFF, chromatography), characterization, and a clean regulatory record. The rankings below score each CDMO on FDA inspections, GMP certification, clinical activity, and capacity.
FDA inspection outcomes across these CDMOs: 1 NAI (no action), 0 VAI (voluntary action), 0 OAI (official action). Leading inspection & GMP sites: United States (1).
