Proof-of-Concept Testing

Proof of Concept (POC) testing is the initial stage of product commercialization. The development in this stage involves taking an idea and conducting enough research to prove that the idea is feasible and can work. Walker Downey & Associates, Inc. prides itself in being able to offer POC testing in the domestic pig (sp. Sus scrofa) using our dedicated animal isolation facility. For all POC testing, animals of the client’s desired age/weight are carefully selected from our reputable supplier, physically examined for good health by our veterinarian, and monitored round-the-clock by our dedicated animal caretaker.

Walker Downey & Associates, Inc. will collaborate with you early in product development to provide critical proof-of-concept data. We can serve as an incubator for successful biotechnology companies and support fundraising efforts by generating proof-of-concept data, assisting with presentations to investors and serving as a subcontractor on grant proposals.

Experts in large animal studies, we can quickly set up studies to test medical device functionality and safety, drug and biologics safety, or obtain pharmacokinetic profiles or metabolism. We will assist you in selecting the best model for your scientific end-point. Data are presented to you in a written report. We will define and defend our findings in applications for 510(k), IND and NDA before the FDA.


Our Peterson Isolation Facility (PIF) is environmentally controlled to USDA standards and contains four (4) separate stalls that can hold animals of various ages/sizes. Typically a single stall will hold ~15 young animals (6-12 weeks of age). Larger older animals are grouped in smaller numbers, as required by guidelines. We will conduct testing on a single animal and up to our PIF animal number limitation. Please contact us for additional discussion.
