# AI clinical-trial patient recruitment

Machine-learning software that scans structured and unstructured electronic health records to identify patients meeting a clinical trial's eligibility criteria and to score candidate trial sites on live population data, replacing the manual chart review that has made patient recruitment the biggest bottleneck before a trial can even begin.

## Overview and value chain

Markers: [EC: AI-based matching of patients to clinical trials and data-driven trial site selection | OECD: Biopharmaceutical clinical development | Regulator: FDA (US), EMA (EU)]

AI clinical-trial patient recruitment platforms scan structured and unstructured electronic health record data to identify patients meeting a trial's eligibility criteria, replacing hours of manual chart review by clinical-research staff. Deep 6 AI optimizes site selection for clinical trials, letting sponsors base site choices on live population and screening data rather than historical site-performance metrics alone. TriNetX unveiled a conversational AI interface and enhanced API capabilities in January 2026, successfully reducing trial costs and timelines as part of platform enhancements designed to democratize clinical-research analytics. Antidote Technologies' Antidote.me offers AI clinical-trial matching for physicians on an enterprise pay-for-performance model, connecting patients to research directly through referring clinicians. Mendel.ai's software aims to save nurses time in pre-screening, and academic research on end-to-end AI-powered trial-recommendation systems (TrialMatchAI, published in Nature Communications 2026) explicitly frames patient recruitment as a major bottleneck calling for scalable, automated solutions — the problem this whole vendor category exists to solve. Paradigm Health's AI-native solution increased screening capacity by 41% in an August 2026 partnership expanding clinical-trial access with Ochsner Health across the US Gulf South, and the company separately submitted a formal response to FDA's Real-Time Clinical Trials Initiative RFI informed by biopharma sponsors and providers.

The key directions of AI clinical-trial patient recruitment are:
1. **EHR-based eligibility matching:** scanning structured and unstructured patient records to automatically identify candidates meeting a trial's specific eligibility criteria.
2. **Data-driven site selection:** scoring candidate trial sites on live patient-population and screening data rather than relying on a site's historical enrollment track record alone.
3. **Physician and patient-facing matching interfaces:** conversational AI and referral tools that connect physicians and patients directly to relevant open trials.
4. **Screening-capacity expansion at health systems:** deploying AI-native screening directly inside health-system workflows to expand the population that can be screened for trial eligibility.

## US

The United States hosts the leading AI patient-recruitment vendors, several with direct 2026 health-system deployments and platform enhancements.

### Deep 6 AI's site-selection optimization, TriNetX's conversational AI, Paradigm Health's 41% screening-capacity gain
- **Deep 6 AI:** optimizes clinical-trial site selection using live population and screening data rather than historical site performance alone.
- **TriNetX:** unveiled a conversational AI interface and enhanced API capabilities in January 2026, reducing trial costs and timelines as part of a broader effort to democratize clinical-research analytics.
- **Antidote Technologies:** its Antidote.me platform offers AI clinical-trial matching for physicians on an enterprise pay-for-performance model.
- **Mendel.ai:** its software aims to save nurses time in pre-screening, applying AI directly to the recruitment bottleneck that academic research has identified as the field's central constraint.
- **Paradigm Health:** an August 2026 partnership with Ochsner Health increased screening capacity by 41% across the US Gulf South, and the company formally responded to FDA's Real-Time Clinical Trials Initiative RFI.

## CN

China is covered qualitatively rather than by a live-screened Chinese vendor: candidate Chinese AI patient-recruitment firms searched during this screen returned only generic market-research reports and academic commentary, not a confirmed named vendor, so no Chinese company is tabled below.

### No confirmed named domestic vendor; market-research coverage describes the category rather than naming a leader
- **Market coverage without a named leader:** Chinese-language sources describe the AI clinical-trial patient-recruitment market's growth and trends extensively, but this screen did not surface a specific China-headquartered vendor confirmed by name in a live 2026 source.
- **Domestic gap:** no China-headquartered AI patient-recruitment platform confirmed by name was found during this screen.

---

## EU

No EU-headquartered vendor cleared the confirmation bar on this screen distinct from the US-headquartered platforms already tabled; European trial sponsors and health systems are served by the same global vendors listed above.

### Served by the same global platforms rather than a distinct EU-headquartered specialist
- **EU deployment of global platforms:** the vendors tabled above serve EU clinical-trial sponsors and health systems directly rather than through a confirmed distinct EU-headquartered competitor.
- **No distinct EU-headquartered vendor confirmed:** this screen did not surface an EU-headquartered AI patient-recruitment specialist distinct from the platforms already listed.

#### Stage 2: AI eligibility matching
AI models identify patients matching a specific trial's eligibility criteria from the structured data.

#### Stage 3: Candidate patient shortlist
Matched candidates are compiled into a shortlist for clinical-research staff review.

#### Stage 4: Site-selection scoring
Candidate trial sites are scored on live population and screening data to inform sponsor site-selection decisions.

#### Stage 5: Referring-clinician connection
A matched, eligible patient is connected to the trial through their referring physician.

#### Stage 6: Patient enrollment
The enrollment process is completed for the referred, eligible patient, closing the loop from EHR data to enrolled participant.
