The AI-powered clinical trial matching service — built from the ground up on HealthKey's open source infrastructure — is now part of the HealthKey family.
What is CancerBot
CancerBot is the first AI-powered clinical trial matching service built on an open, oncology-grade patient record. It connects cancer patients with potentially life-saving trials in minutes — not months — and shows patients precisely which criteria they meet, and which they don't.
No opaque scores. No black boxes. Every match is explained in plain language so patients and navigators can act on reasons, not guesses.
How It Works
Answer structured questions about your diagnosis, labs, prior treatments, and current status. Your data is stored in CTOMOP format — an open, oncology-grade OMOP extension.
Your CTOMOP profile is evaluated against every open trial by EXACT — HealthKey's open source trial matching engine. Every criterion returns a pass, fail, or indeterminate verdict with the patient value behind it.
See only the trials you're eligible for, ranked and explained. Each match shows exactly which criteria you meet — and why.
A patient navigator reviews your matches with you, answers questions, and supports you through the enrollment process.
What makes it different
Open Source Foundation
CancerBot is built entirely on HealthKey's two open source properties. The patient data model and the matching engine are both on GitHub — so the logic that determines a patient's trial eligibility can be inspected by clinicians, researchers, and patients themselves.
A superset of OMOP CDM v6.0 with oncology and genomics extensions — lines of therapy, TNM staging, genomic assays, biomarker profiles, and a 266-field PatientInfo projection that's purpose-built for trial eligibility matching.

View on GitHubWhy CancerBot was built
"I was diagnosed with follicular lymphoma and experienced firsthand how broken the trial-finding process was. I built CancerBot on HealthKey's open infrastructure so the matching logic could be audited, extended, and trusted — by patients, not just vendors."
— Adam Blum, Founder of CancerBot
Why This Acquisition
CancerBot was founded on HealthKey's open source infrastructure from day one. The acquisition formalises that relationship — bringing CancerBot's patient-facing trial matching directly into the HealthKey platform, and giving HealthKey's PHR users seamless access to personalised, explainable trial matches.
CancerBot's matching runs directly on the HealthKey PHR. Patients no longer need to enter their data twice — their existing record powers their trial matches.
CTOMOP and EXACT remain open and publicly licensed on GitHub. The acquisition changes nothing about their open source status.
HealthTree Foundation, CancerBot, and future partners all run on the same open infrastructure — a shared foundation for patient-owned cancer data.
