Penetrance Precision oncology · Trial matching

Eligibility, line by line.
Cited every time.

Penetrance is an auditable clinical trial matching engine for precision oncology. It reads every inclusion and exclusion criterion, returns a verdict per line, and points to the exact source span in the patient's notes. Deployed on-prem.

01  ·  The problem

Trials can't find their patients.

Clinical trials are how oncology moves forward, yet most fail to recruit enough patients in time. The bottleneck is not interest. It is screening: matching one patient's history against pages of dense eligibility criteria is slow, manual, and easy to get wrong.

01

Screening is done by hand, one chart at a time.

A coordinator reads the full chart, then a protocol's criteria, line by line, ~30 minutes per patient, per trial.

02

Eligibility lives in unstructured text, both sides.

Stage, biomarkers and labs are scattered across notes. Criteria are dozens of free-text lines with negation and thresholds.

03

Existing tools return a score, not a reason.

Black-box matching gives a number. A clinician can't see what it read, so they re-check by hand, or skip it.

Most eligible patients never reach a trial
Every oncology trial, one structured library
02  ·  The scale of it

A bottleneck measured in lost time and missed patients.

The cost is not abstract, it is coordinator hours, trials that close under-enrolled, and patients eligible for a study no one had time to check. We have indexed every oncology trial on ClinicalTrials.gov and broken each into structured criteria; the engine runs on that library.

80%

~30m
coordinator time to screen one chart against one trial.
1/5
fewer than one in five eligible patients is ever screened.

03  ·  What Penetrance is

An auditable trial-matching engine for precision oncology.

It reads the chart, reads the protocol, and shows its work on every single criterion, never one opaque number.

Not a score
Every inclusion and exclusion line gets its own verdict, met, not met, or unknown.
Always cited
Each verdict points to the exact line in the source notes. A coordinator verifies in seconds.
Behind your firewall
Runs on-prem or in your private VPC. Patient data never leaves your network.
Criterion → verdict → citation
04  ·  How it works

The pipeline, from raw records to a cited verdict.

Two streams of unstructured text, the patient's record and the trial's protocol, are made structured, compared criterion by criterion, then ranked. Every step is traceable end to end.

1 · Extract
Turns messy EMR notes into a clean, structured patient profile, the same facts a coordinator would pull, made machine-readable.
2 · Parse
Breaks each trial's free-text eligibility into atomic, testable rules, so every criterion can be checked on its own.
3 · Evaluate
Judges every criterion against the profile, met, not met, or unknown, and cites the exact source line behind each call.
4 · Rank
Aggregates the per-criterion verdicts into a calibrated, ranked shortlist a coordinator can verify in minutes.
The name, reliable expression, by design
05  ·  Who we are

Built on one belief about trust.

Trial matching only earns a clinician's trust when every verdict is shown. A score they cannot interrogate is a score they will not act on, so Penetrance shows its work, always, back to the source.

Our mission

Every cancer patient screened against every trial they could qualify for.

Our vision

Trial matching clinicians trust, shown, sourced, reproducible.

Built by a senior data scientist with seven years across machine learning, deep learning, and AI for medicine, working directly with cancer-center trial offices.

Designing with a small group of cancer centers.

We are onboarding a handful of cancer centers ahead of general availability. If you run a molecular tumor board or lead a clinical trials office, we would like to talk.
