Top Providers of ePRO and eCOA in Clinical Trials

Electronic clinical outcome assessment (eCOA) in clinical trials

In electronic clinical outcome assessments (eCOA), clinical outcome data is collected in clinical trials using electronic devices such as smartphones, tablets, or computers[

]. Patient-reported outcomes (PROs) refer to clinical outcomes reported directly by the patient, without interpretation by a healthcare professional or researcher[

]. Clinical outcomes can include aspects such as a patient’s health status, symptom severity, quality of life, and response to treatment, amongst many other possibilities.[

] Using eCOA in clinical trials can improve data quality and reduce errors that are more common with paper-based methods, through the real-time data input that is enabled through various technologies and setups which we will discuss further in this article before getting to our curated list of 11 reliable providers of eCOA solutions for clinical trials.

eCOA is designed to be implemented over electronic devices such as smartphones, tablets, or computers, and is becoming increasingly popular in clinical trials because it offers several advantages over traditional paper-based assessments. Some of the main working principles involved in eCOA deployment in a clinical study include[

What is the difference between eCOA and ePRO?

eCOA, meaning electronic clinical outcome assessment, and ePRO (electronic patient-reported outcomes) are both digital methods used to collect clinical outcome data in clinical trials, but they are not the same thing.

To begin, eCOA is a broad term encompassing various electronically-assisted methods of collecting data related to the patient’s condition and clinical outcomes. eCOA data can be collected using various devices such as smartphones, tablets, and computers, and enables health outcomes to be reported remotely, in real-time, or even passively. eCOA includes patient-reported outcomes (PRO), clinician-reported outcomes (ClinRO), observer-reported outcomes (ObsRO), and performance outcomes, reflecting the fact that data can be entered by various different actors, be it the patient themself, their caretaker, or their study physician or investigator. In other words, ePRO specifically refers to clinical outcomes reported directly by patients, and is a specific type of eCOA, where eCOA also encompasses other digitally enabled outcome assessments that may involve interpretation by a physician or assistance with data entry by a caregiver. ePRO may be collected using web-based questionnaires, surveys, rating scales, or other types of inquiries.

The purpose of ePRO in clinical trials is to obtain accurate and reliable data directly from patients regarding their symptoms, quality of life, and treatment-related adverse events. This approach empowers patients to engage more actively in their participation, and real-time data entry reduces bias that can arise when patients try to recall how they felt at certain points in the past or when potentially feeling uncomfortable in clinical settings.

Traditionally, patient-reported data were collected through paper-based questionnaires, which are relatively more subject to errors due to incomplete or inaccurate responses. Electronic data collection using ePRO has several advantages over traditional methods, including[

Now that we have covered the utility of eCOA in its various forms, including ePRO, let’s take a look at some of the most widely used and established eCOA/ePRO solutions available for clinical researchers and sponsors.

Questions to ask when choosing an eCOA/ePRO vendor

As clinical trials become increasingly complex, eCOA and ePRO systems have become essential tools for collecting patient data reliably, quickly, and accurately. Choosing the right eCOA/ePRO vendor can be a daunting task given the numerous great options available in the market. Asking the right questions can help you identify a vendor that meets the unique needs of your study or organization. Here are some essential questions to keep in mind when evaluating eCOA/ePRO vendors for clinical trials.

1. Can you describe your experience in the eCOA/ePRO space?

Choosing a vendor with extensive (and relevant) experience in the eCOA/ePRO space is essential. This will ensure that they thoroughly understand the regulatory requirements and industry standards for collecting and managing patient data in clinical trials.

2. How customizable is your eCOA/ePRO system?

Every clinical trial is unique, so it's crucial to choose a vendor with an eCOA/ePRO system that is highly customizable to meet the specific needs of your study. This includes the ability to create custom questionnaires, integrate with other systems, and adapt to different languages and cultures[

3. What types of devices does your eCOA/ePRO system support?

The eCOA/ePRO system should support various devices, including smartphones, tablets, and wearable devices[7]. This will ensure that patients can easily and conveniently complete their questionnaires regardless of where they are or what types of technology they may have access to.

4. How does your system ensure data quality and patient compliance?

Both data quality and patient compliance are critical to the success of a clinical trial. Choosing an eCOA platform with built-in edit checks and validation rules is important to ensure data accuracy and completeness. Ask about features that help keep patients engaged such as reminders and notifications, and try out the interface to ensure it is interactive, intuitive, and user-friendly to avoid potential frustration or loss of interest that could lead to drop-outs.

5. Does your system integrate with other clinical trial systems, such as EDC, IRT/RTSM, and eConsent?

The eCOA/ePRO system should seamlessly integrate with any other eClinical solutions you plan to use or that are already in your workflow, such as electronic data capture (EDC), interactive response technology (IRT/RTSM), and electronic informed consent (eConsent)[

]. This will ensure that data is transferred accurately and efficiently across all systems, removing redundancies and errors related to duplicate data entry and manual validation.

6. Does your system support multi-language studies?

Global clinical trials often require support for multiple languages. Choosing a vendor with a system that supports a wide range of languages (including consideration of cultural nuances) is essential to ensure patient engagement and accurate data.

Finally, it's important to understand the vendor's pricing structure, including any additional fees for customization, support, and training. Ensure that the vendor's pricing aligns with your study budget and requirements. Some providers may offer stripped-down or simplified packages for trials or sponsors requiring only certain core functionalities and wishing to avoid paying for unused features.

Choosing the right eCOA/ePRO vendor is critical to the success of your clinical trial. Ensure you partner with an eCOA and/or ePRO provider that provides the functionalities necessary for your specific trial(s), integrates with any other eClinical solutions you already use or plan to use, offers strong support for both the sponsor and patients, and has a good reputation regarding its use in prior trials.
