ClinicalTrials.gov API.
The platform uses the public ClinicalTrials.gov API as its primary trial source. Each trial record links back to the official ClinicalTrials.gov study page when available.

Transparent limitations of public trial data.
Public trial records may be incomplete, delayed, or changed by the sponsor, site, or registry after Varda Clinical last refreshed the database. Varda Clinical does not estimate participant compensation from a study's phase or type. When a public record mentions compensation or reimbursement, patients should confirm the amount and terms directly with the official study team. Patients, caregivers, sites, CROs, and sponsors should verify all study status, eligibility, location, compensation, and contact information before making decisions.

If a public listing appears outdated or incorrect, email support@vardaclinical.com with the NCT ID and a short description. We will review the public source record and refresh or annotate as appropriate.
