WHO International Clinical Trials Registry Platform (trialsearch.who.int): one search across ClinicalTrials.gov and the WHO primary registries (ChiCTR, jRCT, CTRI, IRCT, DRKS, ANZCTR, ISRCTN, EU CTR/CTIS and more), plus the WHO Trial Registration Data Set for any one trial. It is the practical way to find Chinese, Japanese, Indian and Iranian trials next to the rest.

Tools

• ictrp_search({query?, condition?, intervention?, sponsor?, registry?, recruiting_only?, limit?}) — trials matching a free-text query (titles, conditions, interventions, with WHO synonym expansion) and/or condition / intervention / sponsor fields. Each row carries the trial id, the source registry (code and name), recruitment status, registration date, whether results are posted and the ICTRP record URL. registry keeps only one source registry (ChiCTR, CTRI, IRCT, DRKS, jRCT, CT.gov, …). A search with no matches returns total_trials: 0 with the query used.
• ictrp_trial({trial_id}) — the full record for one trial by its registry id: source registry and its record URL, titles, primary sponsor, status, study type and design, phase, countries of recruitment, conditions, interventions, outcomes, eligibility, sample size, dates, funding sources, secondary ids, ethics review status. An id ICTRP does not know returns found: false.

Every response carries data_as_of (the time the portal was read). ICTRP itself refreshes from the registries weekly; ictrp_trial returns last_refreshed_on for the record.

Use alongside clinicaltrials (the US registry’s own API, richer for NCT trials), isrctn and anzctr.

Data sources

• https://trialsearch.who.int/Default.aspx — free-text search (ASP.NET postback).
• https://trialsearch.who.int/AdvSearch.aspx — field search: title, condition, intervention, primary sponsor, recruiting status.
• https://trialsearch.who.int/Trial2.aspx?TrialID=ChiCTR2400080001 — the public record page for one trial.

The portal has no JSON API. Things the next person would otherwise rediscover:

• Search is a WebForms postback. GET the page for its __VIEWSTATE, __EVENTVALIDATION and the ApplicationGatewayAffinity cookies, then POST the whole form back with TextBox1 + Button1=Search (basic) or the ctl00$ContentPlaceHolder1$txt… fields + btnSearch (advanced). Posting a control the page did not render (e.g. a page size on the first POST) fails event validation and 302s to /NoAccess.aspx.
• Page size is a second postback. __EVENTTARGET=DropDownList1, DropDownList1=100 (basic) or ctl00$ContentPlaceHolder1$ddlPageSize (advanced). 100 is the maximum.
• The advanced search renders no pager, so a field search returns at most the newest 100 trials; the response says so in note when there are more. The basic search pages with __EVENTTARGET=GridView1, __EVENTARGUMENT=Page$N; with a registry filter the tool scans up to 5 pages (500 trials).
• The result count wording changes: “407 records for 385 trials found” vs “1 trial found”. A record is one registry entry; a trial groups the entries that cite each other as secondary ids.
• Country is not filterable. The advanced search’s country filter is a two-step listbox postback and its free-text box did not change the result count when tested (stroke: 18,749 records with and without “China”). Use registry for China/Japan/India/Iran, or ictrp_trial’s countries.
• The XML/CSV export is not used. It sits behind an “I agree” to terms that restrict commercial use of the downloaded data; this pack only reads the public result and record pages.
• An unknown trial id answers HTTP 200 with the empty record template.
• Records include contact persons (names, addresses, phone numbers, emails), including the ethics committee’s contact. The tool does not return them.
• Edge-probed 2026-10-09 from a throwaway wrangler dev --remote Worker: GET 200, search POST 200 (“407 records for 385 trials found for: psilocybin”), record page 200. No bot challenge on any of the three.
