How it works

Three steps, about two minutes

  1. Step 1

    Tell us about you

    Age, sex, and whether you have a diagnosis being studied. Three fields, no account.

  2. Step 2

    Answer a few questions

    Each question is chosen because it narrows your remaining studies the most — not because it is on a form.

  3. Step 3

    Talk to the study team

    Your shortlist shows what the registry lists and what it does not. The team confirms the rest.

What this is

Three things you can check

Every trial is a real registry record
Records come from ClinicalTrials.gov. We never generate, paraphrase, or invent a study — if it is not in the registry, it is not here.
Screening, not a diagnosis
We show which listed criteria you meet and which the registry leaves unstated. Eligibility is decided by the study team after tests no questionnaire can perform.
Your answers stay in this browser
The questionnaire runs against a public registry. No account, no profile, and no answers stored on the server.

Common questions

The things people ask before they call

Does searching cost anything?
No. Searching and screening are free and need no account. The study itself may bill your insurance or cover some costs — that is between you and the study team, and it is written in the consent form.
Will I have to pay for travel?
Sometimes. Some studies reimburse travel or offer a stipend; many do not. The listing and the study coordinator are the authoritative source, not this site.
Could I get a placebo?
Some trials compare a treatment against a placebo. If a study uses one, the consent form says so before you enrol, and you can decline. No study should hide it from you.
How long does a trial take?
It varies from a single visit to several years. The registry lists the expected enrolment, and the study team gives you the actual schedule before you consent.
What happens to my answers?
They stay in your browser. The questionnaire turns them into filters against a public registry; nothing is attached to an account, because there is no account. See the note on the questionnaire itself.
Does this tell me whether I am eligible?
No, and it will not pretend to. It tells you which listed criteria you appear to meet and which the registry leaves unstated. Organ function, imaging results, and measurable disease are assessed by the study team, not by a web form.
Where does the data come from?
ClinicalTrials.gov, the U.S. National Library of Medicine's registry. Every row is a real record; we do not generate studies. This site is not affiliated with or endorsed by NLM.

Not sure where to start?

Answer a few questions and we will show you the studies that remain — and be plain about what the registry does not tell us.
