Early Phase Clinical Trials

Phase I and IB trials represent the first practical tests of your compound’s clinical relevance and commercial viability. They are the culmination of years or even decades of research. Moreover, they set the stage for subsequent studies that will ultimately determine your compound’s efficacy, safety and positive impact on patient’s lives.

Maximizing success in early phase development requires a highly coordinated effort to anticipate potential challenges, recruit the right patients, engage top investigators and design a trial that will build a platform for later-stage success.

PPD’s dedicated team of global experts in early development and clinical pharmacology perform a critical assessment of your compound’s unique attributes to identify areas of strength and potential weakness that could impact the outcome of your trial and subsequent trials. Next, the team develops an integrated, early-phase program that leverages our facilities, site network, operational expertise and development experience to execute your trial in patients and/or healthy volunteers. Each step of the process is conducted with an eye toward supporting later-phase programs and regulatory submissions.
