PHT

PHT Corporation was a leading provider of electronic Clinical Outcome Assessment (eCOA) solutions for the global clinical research industry. The company specialized in capturing patient-reported outcomes (ePRO) and clinician-reported outcomes (ClinRO) using digital devices to ensure data accuracy and regulatory compliance. Their product suite, including the LogPad and SitePad systems, replaced traditional paper diaries with electronic interfaces that improved patient engagement and trial oversight. PHT's solutions were utilized in hundreds of clinical trials globally, supporting the development of numerous approved therapies. In 2015, the company was acquired by ERT (now Clario), integrating its market-leading eCOA capabilities into a larger clinical trial technology platform.
