Clinical Trials Registry

IntuiTek · Trial landscape research

Export ClinicalTrials.gov study records for trial landscape and sponsor research. Find studies for a condition or sponsor, then review a consistent table of study titles, status, phase, sponsor and registry updates. Every record includes a link to its official source.

Run your first search

1. Open Try for free and sign in to Apify. Enter a Condition or disease and, optionally, a Sponsor.
2. Choose Maximum studies. Start with 20 studies, which have a maximum result charge of $0.16 at the current price. Review the run options and set a finite maximum cost before starting.
3. Start the run. When it succeeds, open Search summary to check coverage, then Studies to review your records.
4. For a spreadsheet, choose Export → All fields → CSV → Download. Keep the search summary with your export so its coverage is clear. CSV flattens lists into columns and represents missing values as blank cells; use JSON when you need the original list and null types.

The example condition is diabetes. Clear it when searching only by sponsor, exact study IDs or another filter. All filters you leave filled are combined. More search filters contains study status, update date, exact IDs and additional terms. Advanced run settings contains optional request and time limits; the supplied defaults are suitable for a small first search.

An Apify account is required. The platform's “Try for free” button does not guarantee a free run: usage depends on your available credit and account terms. No ClinicalTrials.gov API key, proxy or language-model account is needed.

Understand your results

View	What you get
Search summary	A readable study count and a clear explanation of whether the query finished or stopped at a limit.
Studies	A focused table of study titles, registry status, sponsor, phase, update dates and source links.
Source details	A second dataset view with source references, retrieval time and record identifiers.
Technical summary (JSON)	Machine-readable counts, query identifier and completeness report for integrations.

A successful run can contain only part of the matching studies. Complete query means the source returned no further page for your query. Capped means a study, page or budget limit stopped the export. Zero studies in a complete query means no matches were returned; zero studies in a capped query does not establish that there are no matches. A failed run may contain partial records without a final summary.

For a larger landscape, review the summary before deciding whether to increase limits. Separate runs can overlap and charge again for the same studies; this product does not automatically track changed fields or deduplicate across independent runs.

Pricing

$0.008 per delivered study — $8 per 1,000 studies.

Studies delivered	Result charge
20	$0.16
100	$0.80
1,000	$8.00

These fractional-cent charges accumulate as usage against your Apify account or available credit; there is no separate checkout for each study. The current Actor price includes platform usage and has no configured start fee. Search summaries and empty results add no study charges. Your Apify plan, credit availability and account requirements still apply. Check the Pricing tab for the active price.

The saved Console budget is specific to that saved run setup. API callers must supply their own finite maximum charge; the Actor does not impose an account-wide spending cap. Interrupted runs may already contain billable studies. Inspect them before retrying.

Source and scope

ClinicalTrials.gov's source API is public and free. IntuiTek adds normalized fields, validation, bounded pagination, clear coverage reporting and delivery into Apify. This is a research data tool: it exports public registry metadata, not patient records or medical recommendations. A recruitment status reflects what the registry reports and is not independent confirmation that a site is currently recruiting.

For example, a real completed exact-ID search on 2026-10-17 returned the following registry record:

Study	Sponsor	Registry status	Phase
A Trial of HR17031 Injection With Hepatic Insufficiency	Jiangsu HengRui Medicine Co., Ltd.	Unknown	Phase 1

The historical record and exact input are included below for reproducibility. Registry information can change.

Developer reference

The input remains a flat JSON object. This bounded example combines a condition and recruitment status:

{
  "condition": "diabetes",
  "statuses": ["RECRUITING"],
  "maxItems": 20,
  "pageSize": 20,
  "maxPages": 5
}

For exact identifiers, use ids rather than entering an NCT identifier as a text search:

{"ids":["NCT05151705"],"maxItems":2,"pageSize":2,"maxPages":3}

At least one condition, term, sponsor, identifier or update date is required. updatedSince accepts an inclusive YYYY-MM-DD date. Status values use the registry's uppercase names, such as RECRUITING, COMPLETED or UNKNOWN. These are search filters, not conclusions about clinical outcomes.

Results and completeness

The Studies output contains the full normalized records. The table provides an overview and a separate Source details view. Exported fields include NCT ID, title, status, type, phases, enrollment, sponsor, conditions and registry dates. Missing values remain null; zero enrollment and false flags retain their meaning. Dates preserve the precision provided by the registry.

The Technical summary (JSON) output is a separate machine-readable summary. Search summary presents the same completion status in readable form. Always inspect the summary before treating an export as exhaustive:

Summary	Meaning
complete: true, stopReason: exhausted	The upstream API supplied no continuation token. Zero rows means no matching records were returned for that query.
complete: false, stopReason: maxItems	The requested result limit stopped the export.
complete: false, stopReason: maxPages	The page limit stopped the export.
complete: false, stopReason: budget	The remaining event budget could not cover another whole row.

A successful run can intentionally be partial. A failed run can contain partial data and may have no final summary; inspect its status and error rather than interpreting it as an empty successful search.

recordHash identifies normalized study content. queryHash binds a row to its query and limits. The registry can change between pages and runs, so an export is not a transactional snapshot or an automatic change feed. Independent runs can contain the same study.

Example from a completed run

This illustrative record was captured on 2026-10-17 in a real completed run. The input, full delivered study record and completeness report below were retrieved directly from that run's storage. The record links to its official registry source. Registry information can change; these are historical reported values, not medical advice or verification of treatment safety, effectiveness or current recruitment.

Completeness report:

  "finishedAt": "2026-10-17T15:59:34.067Z"
}

Here, complete: true applies to the exact-ID query. The single delivered record has the same query hash as the summary; its UNKNOWN status and hasResults: false are preserved as reported.

Limits and billing

maxItems supports 1–1,000 rows; pageSize supports 1–100; maxPages supports 1–100. Source requests are serial and start at most once per second. Reads have bounded retries and timeouts. Large or slow queries can stop before exhausting the source; use the summary to distinguish that outcome.

Where paid pricing is enabled, the pricing tab governs the price per delivered default-dataset item. There is no separately configured start fee. Summaries, empty results and duplicate IDs suppressed within the same run do not add dataset items. An interrupted run may already have delivered billable rows. Do not blindly repeat a failed paid run: inspect its dataset and contact the operator if delivery is uncertain. This service does not promise exactly-once delivery across network failures or independent runs.

No source API key, proxy or language-model account is required. Your Apify authentication and platform account requirements still apply.
