Find clinical trials a glioblastoma patient can actually join.
Glioblastoma (GBM) is a serious brain cancer. Clinical trials test new treatments, but each one has strict rules about who can join. This tool reads a patient's information, checks it against those rules, and shows the trials that fit best. If something's missing, it tells you the exact test that's needed — it never just guesses.
See it work — pick a patient.
Three real example patients. Click one and watch the tool go from a doctor's note to a ranked list of trials — with a plain-English reason for every answer. Every result below is the actual engine output, checked against the golden answer key.

Glioblastoma gives you months, not years — and the clock starts at diagnosis.
Glioblastoma is the most common malignant brain tumor, and one of the deadliest: median survival is about 12–15 months. A clinical trial is often a patient's best shot at a newer treatment, but there are thousands of trials, each with pages of eligibility rules, and families are asked to sort through them during the hardest weeks of their lives. Matching by hand is slow, and a single missed rule can mean chasing a trial the patient could never join — or overlooking one they could. This tool does that first-pass sort in seconds, and when a record is incomplete it says exactly which test is still needed instead of guessing.
Good fit, doesn't fit — or honestly, not sure yet.
Most tools force a plain yes or no. But a patient's records aren't always complete. Forcing a guess could sign someone up using facts no one checked, or hide a trial that might actually work. So this tool has a third answer — “not sure yet” — and instead of guessing, it tells you what's missing.

From a pasted note to a ranked shortlist.
Read the info
Paste a doctor's note or upload a PDF. The tool pulls out the key facts, and leaves anything unclear blank on purpose.
Check the rules
For each trial, every rule is checked against the patient: pass, fail, or missing.
Give an answer
A clear “no” beats a “maybe.” Anything unknown becomes “not sure yet” — never a silent yes.
Rank & locate
The best fits go to the top, and trials with a site closer to the patient get a small boost.

Why this is hard
Glioblastoma (GBM) is the most common and one of the most aggressive brain cancers. Trials open and close all the time, and whether a patient qualifies depends on details scattered across different reports — the stage of the disease, how well the patient can handle daily life, specific lab and gene tests, and past treatments — often measured at different times.
Often a single detail decides everything. In 2021, doctors updated the official definition so that “glioblastoma” always means a specific gene result. Because of that, a similar-looking tumor with a different gene result can qualify for some trials but not GBM-only ones. Getting that difference right is the difference between a real option and a dead end.
The main idea, and why it's safe
Each rule is labeled strict (a hard requirement) or soft, and every patient detail says what should happen if it's missing:
- Must-have facts — age, diagnosis, stage. If one is missing, the tool stops instead of guessing.
- Test results — gene and lab tests, health score, past treatments. If one is missing, the trial becomes “not sure yet,” and the tool says which test is needed.
- Tumor type — the tool carefully tells GBM apart from other high-grade brain tumors, exactly the way the trials do.
Reads notes and PDFs
Paste a doctor's note or upload a report. It's careful on purpose — if something's unclear it stays blank, so it becomes “not sure yet” instead of a wrong guess.
Live recruiting trials
Pulls trials that are recruiting right now from ClinicalTrials.gov — the official U.S. government database — including who can join and where the sites are.
Finds nearby sites
Measures how far the patient is from the closest trial site and gives closer ones a small boost — but never enough to push an unqualified trial ahead.
Ranks the best fits
Trials that pass more of the strict rules rank higher, so a precise, well-matched trial beats a loose one that barely checks anything.
Tells you what's missing
For every near-miss, it lists the exact test to get done — a specific lab or gene test — to turn a “not sure yet” into a match.
Proves it's right
A built-in test checks the tool against a known answer key, every single case. The “it works” claim is something you can actually check, not just a promise.
Here's how I checked it: I run the tool on 25 example patients and compare its answers to an answer key. To build that key, I worked through each trial's eligibility requirements with the help of both ChatGPT and Claude, compared their readings, and reconciled any disagreements before locking in the expected answers. The tool has to match all 625 patient-and-trial cases — and every “not sure yet” has to ask for the right missing test. It does, exactly.
What this tool is
A helper, not a doctor. It checks the parts of trial eligibility that a computer can check from clear facts, and shows options with a plain reason for every answer.
Every match it shows is a starting point for a conversation — it comes with the reason it fits, or the exact test still needed — so a doctor can act on it.
What it is not
It is not a replacement for the full trial rules, whether a site has open spots, or a doctor's judgment. The rules it checks are only part of the full picture.
The 25 example patients mix real, anonymized data with a clearly-labeled made-up layer that exists only to test every rule — it's never shown as real patient data.
Try it with a patient.
Paste a doctor's note to fill the form automatically, or type the details in yourself. Leave anything you don't know blank — the tool will mark those trials “not sure yet” and tell you exactly what's needed. It never guesses.
