What is Trial Matcher (Preview)?

The Trial Matcher is an AI model, offered within the context of the broader Azure AI Health Insights. Trial Matcher is designed to match patients to potentially suitable clinical trials or find a group of potentially eligible patients to a list of clinical trials.

• Trial Matcher receives a list of patients, including their relevant health information and trial configuration. Then it returns a list of inferences – whether the patient appears eligible or not eligible for each trial.
• When a patient appears to be ineligible for a trial, the model provides evidence to support its conclusion.
• In addition to inferences, the model also indicates if any necessary clinical information required to qualify patients for trials has not yet been provided by the patient. This can be sent back to the model to continue the qualification process for more accurate matching.

Two different modes

Trial Matcher provides the user of the services two main modes of operation: patient centric and clinical trial centric.

• On patient centric mode, the Trial Matcher model bases the patient matching on the clinical condition, location, priorities, eligibility criteria, and other criteria that the patient and/or service users may choose to prioritize. The model helps narrow down and prioritize the set of relevant clinical trials to a smaller set of trials to start with, that the specific patient appears to be qualified for.
• On clinical trial centric, the Trial Matcher is finding a group of patients potentially eligible to a clinical trial. The Trial Matcher narrows down the patients, first filtered on clinical condition and selected clinical observations, and then focuses on those patients who met the baseline criteria, to find the group of patients that appears to be eligible patients to a trial.

Trial information and eligibility

The Trial Matcher uses trial information and eligibility criteria from clinicaltrials.gov. Trial information is updated on a periodic basis. In addition, the Trial Matcher can receive custom trial information and eligibility criteria that were provided by the service user, in case a trial isn't yet published in clinicaltrials.gov.
