You want the best-performing sites with a patient population representative of your target market. You want experienced staff, down to the site level. And, you want complete data to inform early decisions.

These aspects of site selection and enrollment are often promised, but are they attainable? Yes. They’re possible with PPD.

Going beyond traditional CRO-site models, PPD leverages the sites it owns and the PPD Select network, our top highest-performing sites based on past performance. PPD Select sites leverage streamlined feasibility processes to achieve 30% faster startup, while our Accelerated Enrollment Solutions (AES) sites achieve 2x faster enrollment than industry average.

Data are the currency of clinical trials. The better the data, the more precisely you can plan, budget and execute.

Not relegated to a single source, PPD leverages de-identified, pre-identified and fully identified patient data to determine feasibility and accurately predict true enrollment.

Looking beyond your own trial’s footprint, PPD evaluates local competitive environments to identify concurrent trials, epidemiologic trends and other key determinants of recruitment success in each geographic region.

When it’s time to scale up, PPD’s site network — and site-level infrastructure — is built for immediacy and flexibility globally.
