Thank you for visiting our website. Our goal is to introduce our “turn-key” clinical research capabilities alongside our enduring commitment to ophthalmology.
Drawing from many years of vigorous participation and a broad network of mature contractors in the ophthalmic community, PRN capably provides all aspects of clinical trial management and consulting in both the US and EU.
PRN’s mission is to fight blindness through outstanding research and development advice.
PRN was founded by Dr. William Stewart and his wife Jeanette Stewart in 1999 as 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 69 trials for 18 sponsors, from large pharmaceutical companies to startups, 51 of which were conducted in the US and 18 in Europe and the rest of the world. Four projects had more than 100 sites; the largest project included approximately 7,500 subjects and the duration of the longest project was 3 years. PRN has an outstanding contractor retention track record; to date almost every project has been completed by the project team initially assigned.
