YPrime eCOA makes the study easier for participants and sites, so the endpoint data holds up.
Electronic clinical outcome assessment (eCOA) is the clinical trial technology that captures endpoint data directly from participants, sites, clinicians, and observers on validated electronic instruments. It covers ePRO, eClinRO, eObsRO, and ePerfO in one place, replacing paper with time-stamped, audit-ready data.
Clinical trials demand accurate, timely, patient-friendly data collection across regions, languages, and complex protocols. YPrime eCOA combines configurable workflows, advanced reporting, and participant-centered design to support global trials without compromising compliance or data integrity.
Speed, flexibility, and certainty in every study
YPrime’s configurable eCOA software adapts to protocol complexity, regional requirements, and mid-study change, without slowing trials down.
Speed
A pre-validated eCOA platform cuts build, translation, and validation timelines, and rapid updates absorb protocol amendments without rework.
Data quality
Investigators review and sign off electronically, edit checks catch problems at entry, and every entry, update, and correction stays traceable.
Global execution
AI-powered localization covers 250+ languages across 100+ countries, with device strategies that suit each region and population.
The eCOA Portal
Sites should spend their time on participants, not on your software.
The YPrime eCOA Portal lets sponsors and sites manage participant workflows, maintain visit schedules, and see study progress in one place, with the setup work already done.
✓ Effortless management
Intuitive tools for quick setup and streamlined participant tracking, tuned to the site user experience.
✓ Flexible scheduling
Adapt visit schedules to real life at the site, which keeps windows intact and reduces avoidable queries.
✓ Real-time insight
Dynamic reporting across the study, so decisions rest on current data rather than last month’s extract.
Patient Engagement
Adherence is a design
problem, not a
reminder problem.
Missed diary entries and dropout rarely come from unwillingness. They come from participants not knowing what happens next. The YPrime Participant Hub embeds structured guidance directly in the eCOA app, so the study explains itself, visit by visit.
Better engagement is not a soft benefit. It shows up as completion rates, cleaner endpoint data, and fewer queries at database lock.
Explore patient engagement →Guided experience
In-app study guidance and real-time visit visibility through the Participant Hub.
Device flexibility
BYOD, provisioned devices, or both in the same study, per region and population.
Connected devices
Integrations with wearables, glucometers, and sensors feeding the same record.
Global access
Localized experiences for global populations across 250+ languages.
AI in platform builds
YPrime incorporates AI in
platform builds carefully,
ensuring no access to
patient data.
AI is used to accelerate the build and ensure quality, with human accountability at every step. It is built into processes across the YPrime eCOA build, from specification and configuration through testing, localization, and documentation. Two of them show what it changes for your timeline and your data.
AI-powered localization
Translation and in-app localization across 250+ languages and 100+ countries, drafted by AI and reviewed by linguistic specialists. Screen-level context comes with the text, so reviewers see how a translation behaves in the instrument rather than in a spreadsheet.
Speed: translation moves off the critical path for startup and amendments
Quality: consistent terminology across locales, with linguistic validation preserved
AI-assisted calculations
Scoring algorithms, derived endpoints, and edit-check logic are generated and cross-checked against the instrument specification, then verified in validation. Thorough checks that once took days run in a fraction of the time, so teams can test more scenarios before go-live.
Speed: less manual specification work and fewer build-test-fix cycles
Quality: more thorough verification in less time, supporting better data quality across the study
AI supports work across the platform, well beyond localization and calculations. Ask us where else it applies to your study.

eCOA case study · Pediatric migraine
eCOA for pediatric clinical trials: capturing migraine events as they happen
Pediatric migraine studies have to capture unpredictable symptom onset and patient response. In a global trial spanning 200+ sites and more than 800 participants, a pharmaceutical leader’s existing eCOA platform could not support real-time event documentation or offline randomization.

Timed assessments per qualifying migraine event
Offline
Randomization triggered from the participant’s device, no connectivity required
Challenge
Migraine episodes arrive without warning, often away from connectivity, and young participants need instruments they can actually understand.
Delivered
A pediatric-friendly eCOA build: seven timed questionnaires triggered after each qualifying migraine event, randomization triggered from the participant’s device that works offline, age-appropriate visual interfaces, daily check-ins between episodes, and visual medication guidance with dosing confirmation.
Results
Rolled out ahead of First Patient In (FPI) and stable across an extended study: consistent data collection from all 800+ participants, reliable real-time capture across 200+ sites and multiple languages, and high retention and compliance from the patient-centered design.
“YPrime has a clean and seamless UI. It is able to take the data and put it into graphs and figures to show where the data is trending.”
