Search
Studies with results posted on ClinicalTrials.gov are usually completed. Use Status: All statuses or Completed to broaden the result set.
Live ClinicalTrials.gov API search is active. This tool can load up to 1,000 records per search. ClinicalTrials.gov may have more matching records, so use specific search terms and filters when possible. Charts and preview filters are based only on the loaded records.

Intervention Types
Preview filter — applies only to loaded records, not the full registry.
Number of trials by enrollment size
Based on enrollment count as registered on ClinicalTrials.gov for the records loaded in this search. Values may be anticipated (planned) or actual — check individual records. Does not reflect actual recruitment performance, screen-failure rates, or site capacity.
Trials by registered start year
Preview filter — applies only to loaded records, not the full registry.
Preview only — filters loaded records, not the full registry. Does not change the ClinicalTrials.gov search.
Countries
Top countries are clickable preview filters. "Other countries" is a grouped display bucket and is not clickable.

CSV export reflects the records currently visible in the results table. Search details export documents the search, filters, counts, source, and limitations. Both are based on records loaded in this search, not necessarily all matching records on ClinicalTrials.gov.
Limitations
Outputs are based on a limited preview set of public ClinicalTrials.gov records and do not determine feasibility, predict recruitment performance, recommend sites, identify vendors, or use private clinical operations data.
Public registry data generally cannot confirm: actual site enrollment performance, PI interest or availability, sponsor budget, CRO or vendor identity, recruitment velocity, screen-failure rates, site capacity, or protocol feasibility.
"Results posted on ClinicalTrials.gov" means structured registry results have been submitted to the ClinicalTrials.gov record. It does not necessarily mean a peer-reviewed publication is available.
The ClinicalTrials.gov Visual Navigator is not a standalone feasibility, site-selection, or recruitment-prediction engine. It can support early trial landscape exploration and feasibility-support discussions by making public registry data easier to search, visualize, trace, and interpret.
About this project
This tool was built as a learning and portfolio project to explore how public clinical trial registry data can be made more accessible through search, visualization, and traceability. It uses the ClinicalTrials.gov API v2 to fetch public records in real time.
It is not affiliated with ClinicalTrials.gov, the National Library of Medicine, or any sponsor, CRO, or clinical operations organization. Outputs reflect public registry data as loaded and have not been independently verified against the source ClinicalTrials.gov records. The project owner does not accept responsibility for decisions made based on this tool.
