Non-Human Primate Studies

Incomparable Translational Relevance for Critical Therapeutic Assets

For today’s most advanced therapeutics — including complex biologics, cell and gene therapies, and vaccines — the cynomolgus non-human primate (NHP) model is the indispensable bridge to human clinical trials. BioLegacy leverages NHPs profound immunological, metabolic, and genetic parallels to humans for sponsors’ most critical safety and efficacy studies. Our expertise in navigating the complexities of NHP research ensures the generation of definitive, translationally relevant data to de-risk your most innovative programs and meet the stringent expectations of global regulatory agencies.

BioLegacy maintains an on-site, AAALAC-accredited non-human primate colony, ensuring that studies can be initiated rapidly without the significant delays often associated with sourcing. Combined with our experienced scientific and veterinary staff, BioLegacy provides unparalleled skill and agility in study design and execution, providing sponsors with a clear, predictable path to confident first-in-human dose selection and successful IND submissions.

A Leader in Bioethics & NHP Animal Welfare

Exceptional science is inseparable from exceptional ethics. BioLegacy’s leadership in non-human primate welfare is reflected in a comprehensive husbandry program that goes beyond basic regulatory compliance. We are committed to the principles of the “3Rs” (Replacement, Reduction, and Refinement), ensuring studies are conducted with the utmost respect for our animals. Our husbandry practices are designed to support the complex psychological and social needs of NHPs, because their well-being is not only an ethical imperative but is also essential for generating robust, reliable, and translatable scientific data.

  • AAALAC International Accreditation
  • IACUC Oversight
  • Comprehensive Veterinary Care from board-certified veterinarians.
  • Social Housing & Enrichment provides opportunities for species-typical behaviors, including foraging, climbing, and socialization.
  • Specialized Staff & Training dedicated to NHP care and handling
  • Positive Reinforcement Training (PRT) trains animals to cooperate voluntarily with common procedures, reducing stress and improving well-being.
  • Transparent Operations: Sponsor site visits and full transparency into our animal welfare programs.
De-Risking the Most Advanced Therapies

As therapeutic innovation moves toward complex biologics, including antibody-drug conjugates (ADCs), and advanced therapy medicinal products (ATMPs), predicting human safety and efficacy becomes exponentially more complex. De-risking these programs requires a translational model with profound immunological and physiological fidelity to humans. BioLegacy specializes in designing and executing NHP studies that interrogate the risks of novel modalities, from immunogenicity and cytokine release to biodistribution and on-target toxicity, providing the data you need to confidently proceed to clinical trials.

  • Complex Biologics & ADCs: We evaluate all formats (mAbs, bispecifics, ADCs, etc.), including comprehensive immunogenicity (ADA/NAb) and PK/PD characterization.
  • Gene & Cell Therapy / ATMP Programs: Safety, biodistribution, and shedding studies for AAV, lentiviral, and cellular therapy platforms.
  • Cytokine Release Syndrome (CRS) Assessment: In vitro screening and in vivo monitoring capabilities to evaluate and mitigate the risk of CRS.
  • Integrated Biomarker & Bioanalytical Support: In-house ligand-binding (MSD, ELISA) and flow cytometry platforms to correlate exposure with pharmacodynamic response.
  • Targeted Therapeutic Area Expertise: Proven NHP models in immunology, infectious disease, neuroscience, and ophthalmology to assess efficacy for advanced therapeutics.
