Hagimo's CTI database includes more than 200,000 accredited and verified US-based trial investigators with full contact information, specialty and license information, trial participation histories, and more. Hagimo's CTI database is the largest privately-held database of US-based clinical trials investigators available anywhere. The data has been sourced and aggregated over nearly a decade from multiple sources and has been fully cross-referenced with Hagimo's 'US Medical Providers' (~6.6M medical providers with full contact information). Additionally, information on studies each investigator has participated in are included (with links to clinicaltrials.gov study pages), and FDA' Clinical Investigator Inspection List' inspection results have been integrated as well. Hagimo can also provide additional information, such as referral patterns (in and out) and local populations of eligible patients based on trial cohort specifications - please inquire for more information. Too often, clinical trial investigators are chosen based on 'we've worked with him before', or 'he's a thought-leader in the field', etc. If you want sites that successfully enrol, if you want investigators that consistently perform, select them based on their experience, their success, and their clean audit records; otherwise, you'll get what so many studies get all too often - underperforming sites that don't enrol and don't perform.
