Guides and comparisons for outsourcing drug development
Practical, neutral resources for biotech and pharma teams sourcing CRO and CDMO partners across discovery, preclinical, clinical, and CMC. Written by the BioBridgeX team.
Guides
In-depth, practical explainers on outsourcing drug development, from IND-enabling studies to choosing a CRO.
CRO vs CDMO vs CMO: What Each One Actually Does, and When to Use Them
CRO vs CDMO vs CMO, explained by an outsourcing practitioner: what each actually does, where they overlap, and when to engage which across the drug lifecycle.
What Is a CDMO (Contract Development and Manufacturing Organization)?
A CDMO develops the process and manufactures your drug under GMP. See what CDMOs do, the modalities they cover, and how a CDMO differs from a CMO and a CRO.
What Are IND-Enabling Studies? The Preclinical Package That Gets You to First-in-Human
IND-enabling studies are the GLP tox, safety pharmacology, ADME/DMPK, genotox and CMC work before an FDA IND. See the package, timelines, costs and how to outsource.
How to Choose a CRO: A Practical Selection Framework for Drug Developers
How to choose a preclinical CRO: scope, GLP/GMP/GCP fit, capacity, quality systems, pricing, IP, references, and the red flags that wreck programs.
