What you need to know

What is a Clinical Trial?

A clinical trial tests new medications, treatments, or medical devices in volunteer participants. Before reaching this stage, every treatment undergoes years of laboratory and preclinical testing and must receive FDA authorization.

At CRP, we conduct Phase 2 through Phase 4 trials. Every study is overseen by the FDA, approved by an independent Institutional Review Board, and supervised by our board-certified physicians. Over 500 trials since 1996.

Each study has specific eligibility criteria based on age, medical history, current medications, and the condition being studied. Some studies are open to healthy volunteers, while others require a specific diagnosis such as Type 2 diabetes, high cholesterol, or eczema.

The best way to find out if you qualify is to browse our active studies or call us at (215) 676-6696. Our team will walk you through the screening process over the phone before you ever come in for a visit.

Your safety is our top priority. Every clinical trial at CRP is:
