About DCT

※ Decentralized Clinical Trial

Patient-oriented clinical trials that do not rely on visits to trial site

Decentralized Clinical Trial (DCT) refers to a clinical trial that does not rely on visits to a trial site by utilizing telemedicine, home nursing and digital devices, such as wearables. DCT contributes to ease the burdens placed on patients due to their physical condition and distance from the trial site, improving patient enrollment and reducing the trial cost related.
