accelerating g.i. research

Founded by noted gastroenterologist Charles W. Randall, Primera is the first CRO that is completely focused on G.I. research. Through our optimized model, Primera can significantly accelerate the initiation of G.I. studies, greatly reducing the cost and time for a trial.

efficiency through expertise

Our team’s presence in the G.I. research community has forged an unrivaled network of investigators throughout the nation. This allows Primera immediate site acquisition and the simplicity of a single contract versus multiple individual contracts, thus decreasing time and expense. From personal relationships developed over the years with numerous physician-investigators, Primera can begin a dialogue with research centers across the country and complete an inventory of sites best suited for each individual clinical trial within days of a sponsor’s request.
