Find a clinical trial
Choose a condition, then filter recruiting trials by phase and Australian sites. Already have a trial ID such as NCT01234567? Enter it below to go straight to that trial. Each result gives you enough to decide whether it is worth opening, and every trial has a plain-English summary of who may be able to join on its own page. Updated daily from public registries. Not medical advice.
Those plain English summaries are AI generated from the official criteria and checked on a sample basis. They can contain mistakes, so confirm anything important with the trial site. How we use AI

What do the trial phases mean?
- Phase 1
- The first tests in people, usually in a small group. Mainly about safety, side effects, and finding a workable dose.
- Phase 2
- A larger group. Looks at whether the treatment actually works for the condition, and keeps checking safety.
- Phase 3
- Larger again, often across many hospitals and countries. Compares the treatment against current standard care. This is normally the last step before a regulator such as the TGA will consider approving it.
- Phase 4
- After approval. The treatment is already approved and in use, and the trial follows how it performs in everyday practice: long-term safety, and how well it works in wider groups of people than the earlier trials covered. A Phase 4 trial is not an early experiment. It studies a medicine a doctor may already be able to prescribe.
- Early Phase 1
- Very small exploratory studies that come before Phase 1 proper, often using tiny doses to see how the body handles a drug.
- Not phased, or Not applicable
- The study is not on the drug approval pathway at all. For example an observational study, a medical device, a behavioural study, or a registry.
Phases describe where a treatment sits in the testing pathway. They are not a rating of how good or how safe a particular trial is. For more on how a treatment moves from research to the pharmacy, see how it works.

This tool shows publicly listed trials. Results give a short extract of a trial's plain-English eligibility summary; the full summary is on each trial's own page. It does not tell you whether you personally are eligible, and it is not medical advice. Eligibility is decided by the trial team, so always confirm directly with the trial site before acting. You do not need an account, and no name or email address is collected to use this page. If a search returns no results we record the search term on its own, with no identifier attached to it — see our privacy policy.
