Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases. In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours, and optionally produces a well-defined JSON output, datasets with results, or files in key-value store. In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server. Actors are written with capital "A". ## How to integrate an Actor? If asked about integration, you help developers integrate Actors into their projects. You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready. The best way to integrate Actors is as follows. In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js.md): ```bash npm install apify-client ``` In Python projects, use official [Python client library](https://docs.apify.com/api/client/python.md): ```bash pip install apify-client ``` In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md): ````bash # MacOS / Linux curl -fsSL https://apify.com/install-cli.sh | bash # Windows irm https://apify.com/install-cli.ps1 | iex ```bash In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/platform/integrations/mcp.md). If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md). For usage examples, see the [API](#api) section below. For more details, see Apify documentation as [Markdown index](https://docs.apify.com/llms.txt) and [Markdown full-text](https://docs.apify.com/llms-full.txt). # README ## WHO ICTRP Clinical Trials Scraper Scrape the [WHO International Clinical Trials Registry Platform (ICTRP)](https://trialsearch.who.int) search portal — a single search interface aggregating clinical trial registrations from 22+ national and regional registries, including ClinicalTrials.gov (USA), EU-CTR/CTIS (Europe), ISRCTN (UK), ChiCTR (China), ANZCTR (Australia/NZ), CTRI (India), DRKS (Germany), jRCT (Japan), IRCT (Iran), and more. HTTP-only, no login, no proxy, no API key. ### What this actor does - **Two modes:** `search` (condition / intervention / title / sponsor / secondary-ID / recruitment-status / date-range) and `byTrialIds` (exact lookup) - **Client-side filters:** phase, source registry, recruiting country, results availability - **Full trial metadata** pulled from each trial's detail page — condition, intervention, sponsor, phase, countries, study type/design, target size, outcomes, results-availability, eligibility criteria (age/gender/inclusion/exclusion), funding source - **Empty fields are omitted** ### Output per trial - `trialId`, `sourceRegistry` — the national/regional registry that owns the record (e.g. `ClinicalTrials.gov`, `ChiCTR`, `EUCTR`) - `title`, `scientificTitle`, `acronym` - `condition`, `intervention` - `sponsor` — primary sponsor - `secondaryId` — supplementary identifier (sponsor protocol number, IND/IDE number), when on file - `recruitmentStatus`, `phase` - `studyType`, `studyDesign`, `allocation`, `assignment` - `gender`, `ageMinimum`, `ageMaximum` — eligibility criteria - `inclusionCriteria`, `exclusionCriteria` — full eligibility criteria text, when split by the source - `sourceOfMonetarySupport` — funding source - `countries[]` — countries of recruitment - `dateRegistration`, `dateEnrollment`, `lastUpdated` - `targetSize` - `resultsAvailable` — boolean - `outcomes[]` — primary/secondary outcome names (up to 10) - `trialUrl` — canonical WHO ICTRP trial detail page (mirror) - `sourceRegistryUrl` — canonical page on the primary registry (e.g. the actual `clinicaltrials.gov` or `chictr.org.cn` page), when linked - `resultsUrl`, `protocolUrl` — links to posted results / study protocol, when published - `recordType: "trial"`, `scrapedAt` ### Input | Field | Type | Default | Description | |---|---|---|---| | `mode` | string | `search` | `search` / `byTrialIds` | | `condition` | string | – | Health condition / disease | | `intervention` | string | – | Drug, device, procedure | | `title` | string | – | Title contains | | `sponsor` | string | – | Primary sponsor (partial match) | | `secondaryId` | string | – | Secondary/supplementary ID (not the primary trial ID) | | `trialIds` | array | – | Exact trial IDs (mode=byTrialIds) | | `recruitingStatus` | string | `ALL` | `ALL` / `Recruiting` | | `dateRegistrationFrom` / `dateRegistrationTo` | string | – | `YYYY-MM-DD` | | `phase` | string | – | Client-side phase filter | | `sourceRegistry` | string | – | Client-side registry filter | | `country` | string | – | Client-side recruiting-country filter (partial match) | | `hasResults` | string (select) | `ALL` | `ALL` / `Yes` / `No` — filter by posted-results availability | | `maxItems` | int | `20` | Hard cap (1-200) | #### Example: recruiting diabetes trials in Germany, phase 3 ```json { "mode": "search", "condition": "diabetes", "recruitingStatus": "Recruiting", "phase": "Phase 3", "country": "Germany", "maxItems": 30 } ```` #### Example: exact trial lookup ```json { "mode": "byTrialIds", "trialIds": ["NCT07670416", "ChiCTR2600127247", "ISRCTN12345678"] } ``` #### Example: trials sponsored by a specific company ```json { "mode": "search", "sponsor": "Pfizer", "sourceRegistry": "ClinicalTrials.gov", "maxItems": 50 } ``` ### Use cases - **Pharma competitive intelligence** — track a competitor's trial pipeline across every major registry from a single feed - **Regulatory / market access research** — monitor trial activity by condition, country, or phase - **Academic research** — bulk-export trial metadata for systematic reviews and meta-analyses - **Patient recruitment platforms** — surface currently-recruiting trials by condition and country - **Investment research** — monitor sponsor trial activity as a pipeline signal ### FAQ **What's WHO ICTRP?** A World Health Organization initiative that aggregates clinical trial registrations from 22+ national/regional primary registries into one searchable index, standardizing on the WHO Trial Registration Data Set. **How is this different from ClinicalTrials.gov?** ClinicalTrials.gov is one of the 22+ registries WHO ICTRP aggregates. Searching WHO ICTRP covers ClinicalTrials.gov *and* every other participating registry (EU-CTR/CTIS, ISRCTN, ChiCTR, ANZCTR, CTRI, DRKS, jRCT, IRCT, and more) in one search. **Why is `secondaryId` different from the trial ID?** WHO ICTRP's "Secondary ID" field holds supplementary identifiers (sponsor protocol numbers, IND/IDE numbers) distinct from the registry's own primary trial ID. Use `mode=byTrialIds` for exact primary-ID lookups. **Why do `phase`, `sourceRegistry`, `country`, `hasResults`, and `secondaryId` filter client-side instead of narrowing the search itself?** The WHO ICTRP portal's phase/country picker controls require JavaScript-driven interactions that can't be reliably replayed as a plain HTTP request, and the server-side `secondaryId` search box does a loose/fuzzy match (verified live — searching `NCT` returned trials whose actual secondary ID had nothing to do with `NCT`). Instead, the actor fetches full trial detail for every search-matched candidate and filters precisely against the real parsed phase/registry/country/results/secondaryId fields — more accurate than the upstream fuzzy match. **Are all of WHO ICTRP's advanced-search checkboxes exposed?** Most are — the ones that map onto a field the actor reliably parses (recruitment status, phase, source registry, recruiting country, results availability). A few niche upstream checkboxes (COVID-19-only, rare diseases/orphan drugs, genome editing, pediatric-only) are not exposed as filters: WHO ICTRP doesn't publish a structured flag for these on the trial detail page, so building a filter would mean guessing from free-text fields (e.g. parsing "Age minimum" strings like `18 Years` / `6 Months` / blank) — too unreliable to ship as a filter. `ageMinimum`, `ageMaximum`, and `gender` are still available as raw output fields for anyone who wants to apply their own logic downstream. **How fresh is the data?** WHO ICTRP re-imports each source registry on its own cadence (typically weekly; some registries daily). Each trial's `lastUpdated` field reflects the underlying registry's own last-modified date. **Is there a rate limit?** No documented hard cap. The actor uses small delays between requests to be polite. **Why do some searches take a while?** `trialsearch.who.int` is a slow legacy IIS server — each trial detail page can take several seconds to render. The actor scans up to ~600 search-matched candidates (6 pages x 100/page) to satisfy `maxItems` and the phase/sourceRegistry/country filters. Broad searches (no client-side filters) usually finish in well under a minute; a narrow phase + registry + country combination layered on top of a broad condition search can legitimately need to scan hundreds of candidates and take several minutes — increase the run timeout under **Run options** for those cases, or narrow the upstream `condition`/`intervention`/`sponsor` terms so fewer candidates need scanning. # Actor input Schema ## `mode` (type: `string`): What to fetch. ## `condition` (type: `string`): Health condition or disease to search for (mode=search), e.g. `diabetes`, `breast cancer`. Leave empty to search by intervention, title, sponsor, or secondaryId alone. If every search filter is left empty, the actor falls back to a demo condition ("cancer") so the daily test run still returns data. ## `intervention` (type: `string`): Drug, device, procedure or other intervention to search for (mode=search), e.g. `metformin`. ## `title` (type: `string`): Restrict to trials whose public/scientific title contains this text. ## `sponsor` (type: `string`): Restrict to trials with this primary sponsor (partial match). ## `secondaryId` (type: `string`): Restrict to trials with this secondary/supplementary ID (e.g. a sponsor protocol number or IND/IDE number) — NOT the primary registry trial ID. To look up an exact trial ID, use mode=byTrialIds instead. ## `trialIds` (type: `array`): Exact WHO ICTRP trial/registration IDs, e.g. `NCT06012345`, `ChiCTR2600127247`, `ISRCTN12345678`. ## `recruitingStatus` (type: `string`): Filter to currently-recruiting trials only, or include all statuses. ## `dateRegistrationFrom` (type: `string`): Only trials registered on/after this date. ## `dateRegistrationTo` (type: `string`): Only trials registered on/before this date. ## `phase` (type: `string`): Filter results to a specific trial phase (client-side, matched against each trial's reported phase). ## `sourceRegistry` (type: `string`): Filter results to trials registered with a specific national registry (client-side). ## `country` (type: `string`): Filter results to trials recruiting in this country (client-side, partial match). ## `hasResults` (type: `string`): Filter to trials that have (or don't have) posted results, mirroring WHO ICTRP's 'Results Only' search option (client-side, matched against each trial's parsed results-availability field). ## `maxItems` (type: `integer`): Hard cap on emitted records. trialsearch.who.int is a slow legacy server — for large values combined with restrictive phase/sourceRegistry/country filters, increase the run timeout under Run options. ## Actor input object example ```json { "mode": "search", "condition": "cancer", "trialIds": [], "recruitingStatus": "ALL", "phase": "", "sourceRegistry": "", "hasResults": "ALL", "maxItems": 20 } ``` # Actor output Schema ## `trials` (type: `string`): Dataset containing all scraped WHO ICTRP clinical trial records. # API You can run this Actor programmatically using our API.
