The cited answer
A short, structured answer where every sentence carries the NCT numbers or PMIDs it rests on. One click opens the source record.
Clinical trial search that answers the question, not just lists records
Ask a clinical question in plain language. ClinicalEvidence searches registered trials and published studies, writes an answer where every sentence is cited to an NCT number or PMID, and puts every matching study in one table you can sort, filter and export.
Why a manual clinical trial lookup takes hours
A registry search returns records, not answers. You type a condition and an intervention, get hundreds of entries, and then the real work starts: opening each record, checking the phase, reading the eligibility criteria, finding out whether results are posted and looking for the paper that reported them.
- Synonyms and drug codes split one question into many searches
- Status, phase and enrolment sit in different parts of each record
- Results live in the registry for some trials and only in journals for others
- Nothing tells you which trials are missing from your list
For a single clinical study search this is tedious. For a landscape question asked by a medical affairs team, a CRO feasibility lead or a clinician preparing a case review, it becomes a day of copying fields into a spreadsheet.
A clinical trial search tool that reads the records for you
ClinicalEvidence understands the question behind your words. Semantic and full text search run together over our index of ClinicalTrials.gov, PubMed, the open access subset of PubMed Central, the EU Clinical Trials Register and the WHO ICTRP where licences allow. The index is refreshed every day.
-
Write the question the way you would ask a colleague, for example which phase 3 trials test a checkpoint inhibitor after progression on first line chemotherapy
-
Narrow the search with filters for condition, intervention, phase, status, study type, date range, sponsor type, country and results available
-
The answer is written only from passages retrieved from the index, never from model memory
-
Automatic citation verification checks that each cited ID exists in the index and that the passage supports the sentence
-
An answer without verified sources is not shown, and when the index holds no evidence you are told so plainly

What you see after every clinical study search
Each question returns three things on one screen, so you never switch between tabs to connect a claim to its record.
The citations and sources searched
A reference list with links to each trial record and publication, and a "Sources searched" panel that lists only the sources actually searched for your question.
The trial table
Every matching study in rows: phase, population, interventions, primary and secondary endpoints, results posted, sponsor, status, enrolment, dates and locations. Sort by any column and filter down to what matters. Read more about the clinical trial table.
Oncology trial search for professionals
Oncology questions are where a simple keyword search breaks down fastest. Tumour type, line of therapy, biomarker status and combination regimens all change which trials are relevant. If you are used to oncology trial finders that filter by cancer type and treatment, ClinicalEvidence adds the step those tools leave to you: a written, cited answer that explains what the trials test and what the published results report, alongside a table you can hand to a colleague.
- Ask about a biomarker defined population and get the trials that enrol it
- Compare regimens across trials with intervention comparison
- Save the question and receive clinical trial alerts when new studies are registered or results are posted
Who uses this clinical trials finder for professionals
ClinicalEvidence is built for people who need to cite what they find. It is a professional research tool, not a service for patients looking for a trial, and it does not give medical advice.
- Physicians and clinical pharmacists checking the evidence behind a treatment decision
- Medical affairs teams answering medical information requests with sources
- Clinical development and CRO feasibility teams mapping competing trials before protocol design
- Researchers and HEOR consultants scoping the trial landscape for a review or a dossier

Clinical trial search questions
Is this different from searching a trial registry directly?
Yes. A registry search lists records that match your terms. ClinicalEvidence searches several registries and the literature together, writes a cited answer and builds a trial table, so the reading and cross checking is done before you start.
Can it invent a trial that does not exist?
No. Every NCT number and PMID in an answer is checked against our index before you see it, and the cited passage must support the sentence. An answer without verified sources is not shown.
How current are the trial records?
The index is refreshed every day, so new registrations, status changes and newly posted results reach your searches within a day.
Can I search for trials that are recruiting in a specific country?
Yes. Filter by status and country, and the trial table shows the locations listed in each record.
Is this a tool for patients looking for a trial?
No. ClinicalEvidence is for healthcare and life science professionals. It summarizes what studies report and does not give medical advice or match patients to trials.
