Understand the cost of using paper PROs

With paper, you could be paying more for less.

See if paper is draining your budget.

Before your next trial, use our paper-cost calculator to estimate the potential expense of your patient-reported outcomes (PROs).


eCOA Platform

Our world-class scientific expertise drives solutions which are built around your patient, powered by innovative technology, flexible device modalities, and supported by over 25 years of experience.

Clario eCOA Live offers patients the choice of how and where to take part in clinical trials

This unique decentralized clinical trial solution enables patients to complete ePROs, which were traditionally done at site, from the comfort and safety of their own home.

Alternative virtual solutions require clinicians to complete these assessments alongside the patient, either via phone or video call. With the eCOA home data assessment tool, live patients enter their responses electronically and in complete privacy. This minimizes the risk of clinician bias and results in more accurate, honest and high quality responses.
