Step by Step: Find a Trial for You on Official Registries
Before you search, get these ready
A little prep makes the search much faster — and much easier to judge which trials might fit you. Before opening the search page, gather these:
- A clear diagnosis name, as specific as possible (e.g. write "non-small cell lung cancer," not just "lung cancer")
- Your current medication list: drug names plus doses — a photo on your phone works
- Test results from the last 3–6 months: pathology, imaging, blood work, and the like
- Key details of your condition: stage, genetic test results (if any), treatments you've already had
- Your city, and how far you're willing to travel (same city? same region? anywhere?)
Only trust official trial registries. Legitimate clinical trials never charge participants — anyone asking you to pay an "application fee" or a "grease fee" is a scammer. Walk away. And don't trust shady "guaranteed enrollment" ads either.
First stop: ClinicalTrials.gov (the world's largest)
Run by the U.S. National Institutes of Health, this is the world's largest clinical trial registry, with trials from around the globe. It's free. Follow these steps:
Step 1: Type a keyword. In the search box, enter your condition's name in English, e.g. "lung cancer." Not sure of the English name? Ask your doctor, or use your browser's translation feature to help.
Step 2: Filter to "Recruiting." In the filters, set the recruitment status to "Recruiting" — that way you only see trials currently enrolling. Skip the ones that have ended.
Step 3: Filter by location. Add your country or city to narrow the results to places you can actually get to — no point getting excited about a trial across the world.
Step 4: Open a record and read the details. Click into a promising listing and focus on the 5 key lines we'll cover below to decide whether it's worth contacting.
Keyword tips: Too many results? Add the stage or gene mutation to narrow it down, e.g. "lung cancer EGFR." Too few? Try a broader term — swap "non-small cell lung cancer" for "lung cancer" and see.
Second stop: WHO ICTRP and national registries
The World Health Organization's ICTRP (International Clinical Trials Registry Platform) lets you search across many countries' registries at once — a great complement to ClinicalTrials.gov.
Many countries also run their own official registries — China, for example, has the China Drug Trials Registry (chinadrugtrials.org.cn), which some patients find easier to use in their local language. They're all free to use.
Our suggestion: check more than one registry. ClinicalTrials.gov has the broadest coverage, while national registries may have details closer to your local hospitals — together, they make it harder to miss something.
Once you find a trial you like, write down its trial number (usually a code starting with "NCT"). When you call or email the study site, quoting the number lets them pull up the trial instantly — it makes the conversation much smoother.
Reading a trial record: focus on these 5 lines
Every trial record is packed with information. Don't panic — these 5 lines are all you need:
1. Title and phase. The title tells you what the drug is and what it treats; the phase (I / II / III) tells you where the trial stands — the later the phase, the more mature the data.
2. Recruitment status. It must say "Recruiting" — you can skip listings in any other status.
3. Inclusion and exclusion criteria. This is the key to judging whether you fit. A shortcut: read the exclusion criteria first — if even one applies to you, you can pass on this trial. That's the fastest way to filter.
4. Study sites and cities. Check which hospitals are running the trial and in which cities — is one near you, and can you manage the travel and follow-ups?
5. Contact information. Records usually list a phone number for the study site or the person in charge. Call them directly with your questions — it's far better than guessing on your own.
Found one — what's next?
Show it to your doctor first. Send the trial link or number to your doctor and ask them to sanity-check it: is this trial legitimate, and does it fit your current condition? Move forward only after your doctor gives the nod.
Contact the study site directly. Call the number in the record, describe your condition, and send your diagnosis and test reports as requested. They'll tell you what tests come next and when to come in for an interview.
One iron rule: never pay. From sign-up to screening to enrollment, a legitimate trial never charges participants. If anyone asks you to pay at any step, stop immediately and tell your doctor. Fee policies differ from trial to trial — clarify them before signing the informed consent form.
