The Registry Ensures Precision Targeting
• Our Registrants have already said “yes” to study participation
Fully HIPAA compliant, the Clinical Trials Candidate Registry contains nearly 3.9 million patients (across all diseases and illnesses) who are actively seeking clinical study opportunities. The CTCR has been created as a repository for patient information involving patients that have already expressed interest in clinical trial participation. The Registry contains detailed medical information about Patients and Subjects from precious PRi clinical trials, and from continuous patient self-reported surveys conducted on behalf of pharmaceutical companies and healthcare providers.
Patient names and data are derived from national and local patient recruiting programs involving radio, television, internet, newspaper advertising and via the incorporation of specific Investigator patient database information. For purposes of clinical and outcomes research, PRi contacts qualified patients via telephone, direct mail, or email. Interested subjects are presented the study opportunity, asked for their permission to proceed, and screened to determine their eligibility for the study.
The CTCR has patients matching almost every disease profile with strong geographic representation throughout the United States.

276,000 CHF
