Frequently Asked Questions

What is an eCOA clinical trial?

An eCOA clinical trial uses technology to accelerate clinical data collection and ensure proper data quality analyses. More sponsors are choosing eCOA for their clinical trials to gain a better understanding of how patients feel and function in near real-time.

What is the difference between eCOA and ePRO?

The difference between Electronic Clinical Outcome Assessment (eCOA) and Electronic Patient-Reported Outcome (ePRO) is that ePRO systems are a type of eCOA. Clinical trial patients often use eCOA system technologies on mobile devices to remotely send their ePRO symptoms and experience directly to site staff. Other types of COAs include Electronic Performance Outcome (ePerfO), Electronic Clinician-Reported Outcome (eClinRO), and Electronic Observer-Reported Outcome (eObsRO).

Does Signant have an instrument library?

Signant’s instrument library contains over 50 instruments commonly used in clinical trials. In many cases, we offer pre-approved versions, which means an author review step is not required. Additionally, our library instruments are designed using best practices and are pre-validated, so they do not require additional testing when implemented in a new clinical study, saving you time and ensuring high quality.

Can you provide scientific consulting to support our eCOA approach?

Signant proudly provides expert consulting with our solutions, like eCOA.
