About CRO
Custom Biologics specializes in GLP-compliant bioanalytical services for biologics, vaccines, and gene therapies across preclinical and clinical development stages. With over 20 years of experience, Custom Biologics has supported more than 200 preclinical and clinical studies for over 125 clients worldwide.
Technology & Expertise
At Custom Biologics, we draw on over 20 years of large‑molecule bioanalytical experience to support biologics, vaccines, cell and gene therapies. Our scientists specialize in functional assays (cell‑based, ligand/receptor binding), pharmacokinetic/toxicokinetic quantification, immunogenicity evaluation and genomics methods for gene‑therapy vectors and transgenes.
Core Services
We offer a comprehensive suite of services that includes assay development and validation (for potency, mechanism of action, and bioactivity), stability and lot‑release testing, pharmacokinetics and immunogenicity studies, and molecular/genetic analyses. Whether for discovery, CMC, or clinical phases, our services are designed for full regulatory submission support.
Accreditations & Compliance
Our operations are run under a rigorous quality system aligned with GLP and regulatory expectations—our independent Quality Assurance Unit ensures adherence to 21 CFR Part 11 and Part 58 guidelines. We also maintain a Canadian GMP Drug Establishment Licence, reinforcing our global compliance readiness.
