What Medellis Match Actually Does

We help you discover trials worth exploring — but final eligibility is always determined by the study team and your doctor.

Filters 1000s
of trials down to a manageable list based on your condition and location
Explains Why
each trial might or might not be relevant, in plain language you can understand
Guides Next Steps
so you know what to ask your doctor and how to contact study sites

Important: This is a Starting Point

  • • Match scores are estimates based on the information you provide — they are not guarantees of eligibility
  • • Only the study team can determine if you truly qualify after a screening visit
  • • Always discuss clinical trial participation with your doctor before contacting a study site
  • • We're a tool to help you discover options — not a replacement for medical advice

Our Multi-Pronged AI Approach

We don't rely on a single method. Each technique catches matches the others miss.

Semantic Search

Vector embeddings understand that "NSCLC" and "lung cancer" mean the same thing

Keyword Search

BM25 full-text search catches exact biomarkers like "EGFR exon 19 deletion"

Eligibility Parsing

LLM structures eligibility criteria, then rule-based matching checks age, stage, treatments

Location Aware

Boosts trials with sites near you — because travel matters for participation

Results are combined using Reciprocal Rank Fusion — a proven method from information retrieval research

Document Extraction

Upload lab results or medical records. AI extracts diagnosis, stage, biomarkers, and treatments to improve matching.

Privacy Focused

Your profile is stored locally on your device. Search queries are processed but we don't permanently store your health data.
