When a clinical trial
can be the only treatment.
Eligible 4 is the European network connecting complex patients to the right clinical trials. AI checks inclusion and exclusion criteria. Doctors refer. The best recruiters get recognised.
- Confirm treatment against past trials
- Find active trials in CT.gov + CTIS
- Accelerate your next study with AI
Three ways we help before the network is full.
Networks take time to grow. The tools are ready today.
Confirm your treatment plan
Validation against published evidence
The AI cross-references your patient profile against the inclusion criteria of completed clinical trials in the same condition. When there's a match, the treatment that trial validated becomes direct evidence for today's decision.
- Comparison against I/E criteria from published phase 2 and 3 trials
- Link to original paper and trial registry
- Useful in refractory and salvage decisions
Find an active trial
ClinicalTrials.gov + CTIS, in seconds
The AI cross-references your patient profile against every recruiting trial in ClinicalTrials.gov and the European CTIS. Returns matches ranked by eligibility and direct contact path to the responsible investigator — including a fast-track invitation to the network.
- Cross-checked against >450,000 indexed trials
- Pre-validation of key I/E criteria
- Network invitation to responsible investigators
Accelerate your next study
Protocol, consent, ethics
When it's your turn to design a study, the AI generates the protocol, informed consent, and Ethics Committee documentation. Before real submission, a panel of 12 specialised agents reviews your package — so the first submission to the ethics committee is the next one to be approved.
- Protocol generation from research question
- GDPR-compliant informed consent
- 12-agent AI panel pre-reviews your submission
- Automated Data Protection Authority report
Anonymize clinical records on-device. Patient data never leaves your browser.
Snap a photo of a paper record, upload a scan, or paste raw text. OCR and a small Llama 3.2 model run entirely in your browser tab — your patient data is never uploaded.
Try the anonymizerA patient on fourth line. A colleague in Porto. A trial in Spain.
Before Eligible 4 existed, a colleague oncologist in Porto found a clinical trial in Spain for a patient on fourth-line therapy. It worked. But it depended on knowing the right person at the right moment — an informal network of phone calls, conferences, and personal contacts.
Eligible 4 exists so cases like this stop depending on the luck of who your doctor happens to know. To make systematic what already happens in fragmented form — because in oncology and rare diseases, a clinical trial can literally be the only treatment available.
“The trial was the only option left. We found it by luck.”— a real, anonymised case
Anonymised case, shared with consent. Pre-Eligible 4.
A good referral is seen — and rewarded.
Doctors refer because it's right for the patient. The network makes that gesture visible, comparable, and — when your institution chooses to — rewarded.
Individual recognition
Every triaged and accepted referral counts towards your public profile on the network. Eligible 4's Hall of Fame shows top contributors by specialty, institution, and country.
Institutional Hall of Fame
Your institution sees its aggregate impact: how many patients referred, how many enrolled, across how many partner centres. Scientific contribution metrics ready to present in board meetings.
Award campaigns
Each institution can launch internal campaigns: "best recruiter of the quarter", "first cross-border referral", "rare disease patient routed to active trial". Eligible 4 provides the auditable ranking.
Where we stand today
The network is in open beta. Each pro tool is open with 100 free uses to try — no card, no individual subscription. Subscriptions are institutional only.
The network also handles referrals for doctoral theses, basic-science sample collection, and scientific collaboration in general — not just clinical trials.
In second-line oncology, weeks lost to a failed screening can be weeks the patient does not have.
Most clinical recruitment platforms optimise for volume: how many patients entered the funnel. The number that counts is different: how many of those patients were truly eligible.
It's called screening failure rate — and in oncology trials, in rare diseases, in refractory populations, it sits between 70% and 85%.
Eligible 4 works to bring that number down two ways:
- AI checks inclusion and exclusion criteria before the referral
- The referral comes from a doctor who has actually seen the patient, not from automated chart extraction
We don't replace clinical judgment. We add a validation layer before the patient leaves the consultation.
Volume-optimised platforms:
- Maximise automated matching
- OCR-scrape patient records
- Funnel against many criteria
Result: 70-85% screening failure
Eligible 4 — quality screening:
- Doctor-to-doctor, validated before referral
- AI on I/E criteria + human endorsement
- Network that rewards precision, not volume
Target: lower screening failure in complex trials
Every patient you fail to enrol is lost revenue — and your next grant depends on it.
80% of clinical trials miss their enrolment targets. Roughly half of all sites under-enrol. See what that costs your institution.
European median. Phase 3 oncology can reach €30-40k. Observational studies sit between €2k and €5k. Adjust to your study mix.
