Who We Are
Precefi was founded by a team of biotech industry veterans with deep experience at companies like Allergan, Regeneron, AstraZeneca, and Incyte — and a track record that includes contributions to the development and approval of Botox®, Eylea®, Kybella®, Opzelura®, and more.
We built Precefi to solve a fundamental problem in clinical research: sponsors shouldn’t have to manage dozens of relationships to run a single trial. Our network of KOL-led dermatology and ophthalmology sites operates under one contract and one price, with integrated biomarker services, our Appiell virtual platform, and a team that understands drug development from the inside out.
We are a site network built on decades of experience, leading KOLs, and a commitment to redefining clinical research.
