The eClinical Ecosystem — Defining the Digital Trial
The term "eClinical" refers to the suite of software applications designed to replace traditional paper-based research. In 2026, the ecosystem is built around four core pillars:
Electronic Data Capture (EDC): The digital "case report form" where doctors and site staff enter patient data.
Electronic Clinical Outcome Assessment (eCOA): Tools that allow patients to report their own symptoms directly via smartphones or wearables (also known as ePRO).
Clinical Trial Management Systems (CTMS): The "operational brain" that tracks site monitoring, investigator payments, and study milestones.
Interactive Response Technology (IRT): Systems that manage patient randomization and the automated supply of investigational drugs.
