Drawing from many years of vigorous participation and a broad network of mature contractors in the ophthalmic community, PRN has the capability to provide all aspects of clinical trial management and consulting in both the US and EU.

PRN was founded by Dr. and Mrs. William Stewart in 1999. After founding and directing a successful ophthalmic site management organization (PRC) in 1992, the Stewarts perceived a need for an ophthalmic specific CRO. PRN was created to provide a superior standard for clinical trials in ophthalmology to the pharmaceutical community.

PRN has managed over 50 trials for 12 different sponsors, 37 of which were conducted in the US and 16 in Europe and the rest of the world. Four projects had more than 100 sites; the largest project included approximately 5,000 subjects and the duration of the longest project was 3 years. PRN has provided consulting advice to more than 20 ophthalmic companies. PRN has an outstanding contractor retention track record; to date every project has been completed by the project team initially assigned.

PRN’s mission is to fight blindness through outstanding research.
