Non-rodent In Vivo PK Service
Creative Biolabs' non-rodent in vivo PK service is designed to deliver definitive exposure and kinetics data essential for advancing your therapeutic candidate. We provide expert selection of the most translationally relevant non-rodent models (NHP, Canine, Minipig) and employ specialized surgical and bioanalytical techniques. Clients gain high-confidence data packages that accurately predict human pharmacokinetics, enabling optimized dosing, mitigating safety risks early, and efficiently meeting all requirements for advanced research applications.
Enhancing Drug Translation via Non-Rodent PK
Non-rodent in vivo pharmacokinetic (PK) studies involve assessing the behavior of drugs within living organisms that are not rodents, such as dogs, non-human primates (NHPs), pigs, rabbits, or other species. These studies are essential in preclinical drug development to understand how drugs are absorbed, distributed, metabolized, and excreted in non-rodent species, which can provide valuable insights into human pharmacokinetics. Non-rodent in vivo PK studies provide valuable insights into drug behavior, efficacy, and safety across various therapeutic areas, complementing rodent models and enhancing the translational relevance of preclinical research.

What We Can Offer
Species for Non-rodent Pharmacokinetics
Non-rodent species have unique advantages and physiological characteristics that, in some cases, can better mimic human pharmacokinetics. Here are some common non-rodent species used in pharmacokinetic studies:
| • Dogs | • Birds | • (Non-Human Primates) NHPs | • Fish |
| • Pigs | • Guinea Pigs | • Rabbits | |
Advantages of Non-rodent Species
Closer Physiological and Anatomical Similarity to Humans
Non-rodent species often exhibit physiological and anatomical similarities to humans in key organs and systems. This similarity can enhance the predictive value of preclinical PK data for human pharmacokinetics.
Metabolic and Renal Function
Some non-rodent species have metabolic and renal functions that are more similar to those of humans, allowing for more accurate predictions of drug metabolism, clearance, and excretion in humans.
Pharmacodynamic Relevance
Non-rodent species may better replicate human pharmacodynamic responses to drugs, allowing for more accurate predictions of therapeutic efficacy and safety.
CNS Penetration and Drug Distribution
Larger non-rodent species, due to their larger size and more developed central nervous system anatomy, provide a better model for studying the penetration of the central nervous system (CNS) and the distribution of drugs in the brain.
Longitudinal Studies and Chronic Effects
Due to its longer life span and larger size, it is more suitable for longitudinal studies and evaluation of chronic drug effects. This allows researchers to assess long-term persistent drug exposure, long-term toxicity, and potential adverse effects.
Translational Relevance
Non-rodent species provide a more translational bridge between preclinical and clinical trials, particularly in assessing drug safety, efficacy, and pharmacokinetics.

Highlights
Biologic PK Expertise
We possess extensive experience with large molecules where challenges like target-mediated drug disposition (TMDD) and immunogenicity are prevalent. Our specialized protocols mitigate the data confounding effects of anti-drug antibodies (ADAs) in NHP studies.
Scientifically Driven Species Selection
Species determination is based on rigorous in vitro and in silico target-homology analysis. This process ensures the selected non-rodent model maximizes the predictive correlation to subsequent human study outcomes.
Advanced Specialized Sampling Capabilities
Our facilities accommodate complex surgical models, including the cisterna magna cannula for conscious cerebrospinal fluid (CSF) collection and bile duct cannulation, essential for comprehensive ADME characterization.
Unwavering Adherence to Highest Quality Standards
All definitive studies are executed within AAALAC-accredited facilities under strict adherence to the highest quality standard compliance. This ensures the data is scientifically defensible and immediately suitable for global advanced research filings.

Customer Reviews
-
High Correlation to Human PK
The integration of the Creative Biolabs' service yielded substantially enhanced translational accuracy for the prospective human starting dose. Specifically, the NHP pharmacokinetic data demonstrated superior concordance with preliminary human study projections, consequently augmenting confidence in the calculated safety margin beyond estimates provided by in silico modeling. - K*n A**s. -
Specialized Dosing Access
Creative Biolabs' capability to perform cervical cisterna magna cannula (CMC) surgery in our canine model was invaluable. We were able to get consistent, high-quality CSF samples to accurately measure CNS penetration of our small molecule drug candidate - a critical data point that few other CROs could offer reliably. - T**y H**t.
FAQs
How to choose non-rodent species?
The choice of non-rodent species for pharmacokinetic studies depends on various factors, including the specific research objectives, drug properties, anatomical and physiological similarities to humans, ethical considerations, availability, and practical constraints. Each species offers unique advantages and may be best suited for specific research questions or experimental conditions.
What specialized sampling is available beyond standard blood collection, and is the data verified to the highest quality standards?
Yes, we routinely perform complex surgical procedures to access unique matrices critical for ADME. This includes sampling CSF, collecting bile via cannulation, and targeted tissue biopsies. All definitive studies are conducted under the strict highest quality standards to ensure the data is suitable for your advanced research application.
