eCOA vs ePRO: Understanding the differences in clinical trials
Digital data capture has become essential to modern clinical research. Sponsors and research organizations increasingly rely on electronic outcome assessment tools to collect high quality patient data, reduce manual errors, and improve regulatory compliance.
Two terms appear frequently in this space: eCOA (electronic Clinical Outcome Assessment) and ePRO (electronic Patient Reported Outcome).
These terms are closely related. However, they are not interchangeable.


eCOA standards and KPIs to include in your next RFI
According to Gartner, a request for information, or a request for proposal, is defined as “both the process and documentation used in soliciting bids for potential business or IT solutions required by an enterprise or government agency. The RFI document typically outlines a statement of requirements (SOR) to be met by prospective respondents wishing to make a bid to deliver the required solutions. It might cover products and/or services to meet the given requirements.”
Yet, for anyone entering into a long-term business agreement, a well-written RFI can do so much more than just assess and collect vendor capabilities.
For the last decade, Medable has been transforming the capabilities of organizations across clinical research using the latest in new technologies. In this time, we’ve learned the best RFIs are able to define what success looks like, create alignment on measurable outcomes, and establish accountability on roles and responsibilities well before a contract is ever signed. When done correctly, it becomes a decision-making framework that offers clear vision to both organizations.
Recently, Medable received two RFIs around eCOA from top pharmaceutical organizations. They stood out to us because they were structured around performance, not promises, a distinction that makes all the difference.


From bottlenecks to breakthroughs: How AI is transforming translation timelines
According to ClinicalTrials.gov, there are 3,046 multi-country trials being conducted this year. While many trials remain localized within a single country, there has been a definitive movement towards conducting trials in multiple countries, especially for larger, later-stage trials. This is driven by the positives that multi-country trials offer, like faster patient recruitment, lower costs in some regions, and the need for diverse patient populations.. However, behind the scenes, a critical bottleneck has been slowing many trials down. This bottleneck is the translation process that’s required to make trials work across multiple languages, locales, and regulatory bodies/organizations.


The Top 5 myths about eCOA in 2025
With MarketsandMarkets projecting the global electronic Clinical Outcome Assessments (eCOA) solutions market to grow at compound annual growth rate (CAGR) of 16.1% each year until 2030, it’s clear the eCOA has made its impact within the clinical research landscape.
Yet despite growing adoption, electronic Clinical Outcome Assessments (eCOA) are still surrounded by misconceptions that hinder their full potential. From concerns about patient usability to assumptions about cost and implementation timelines, these myths can create hesitation among sponsors and research teams alike.
Thus, we’re here to cut through the noise and set the record straight with a summary of a recent webinar featuring speakers from Transcelerate and Medable.

Tips for better eCOA experiences from our Patient Caregiver Network
Electronic Clinical Outcome Assessments (eCOA) have revolutionized data collection in clinical trials, offering convenience and real-time insights that traditional methods cannot match.
However, the effectiveness of these digital tools hinges on the quality of the daily experience they offer participants. Read below to see direct feedback from patients and caregivers across multiple conditions in our Patient Champion Network (PCN), as we identify ten critical factors that can improve the eCOA experience.


The science behind Medable’s HEOR
“No one knows their level of pain and how they feel or function better than the patient. Capturing the patient’s response to an electronic Patient Reported Outcome (ePRO) is always the best option.”
Since its inception, Medable has prioritized scientific integrity and rigor around various aspects of clinical trials. As part of its science team, Cindy Howry, VP of eCOA Science, plays a crucial role in ensuring that Medable’s clinical trial platform accurately captures electronic Clinical Outcome Assessments (eCOAs). Hired in 2023, Howry’s chief purpose at Medable is to ensure that the health economics and outcomes research (HEOR) science behind our technology is based on best practices and regulatory guidance.


Explore Medable Studio
A decade ago, our founders’ experiences in clinical research and life sciences drove them to create Medable, a simple cloud-based platform that could improve theconduct of trials. Over the last ten years, we’ve conducted nearly 400 trials on our platform, continually refining it to provide a better experience for sites, patients, and caregivers.Today, we’re excited to announce that our customers are entering a new era of control, ease of use, and simplicity.


Clinical Leader Solutions Expo: eCOA/ePRO
The next level of clinical trial data capture is here. Gone are the days of paper, illegible handwriting, and data quality nightmares. eCOA, or electronic Clinical Outcome Assessments, and ePRO, or electronic Patient-Reported Outcomes, are revolutionizing the way clinical trials generate data. Both leverage digital tools to collect information electronically, offering a treasure trove of benefits. eCOA acts as the umbrella term, encompassing data from various sources like patients (ePRO), clinicians, observers, and even performance-based assessments. This holistic approach paints a more complete picture of a patient's experience. ePRO, as a subset, shines the spotlight directly on the patient's voice, capturing their symptoms, quality of life, and other critical self-reported measures.

Defining “evidence generation” within modern clinical trials
Medable has always been, at its core, a platform that enables clinical trial sponsors to collect data and generate evidence to answer scientific questions.
But from the start, Medable has done things differently. Today, the flexibility, purpose, and build of Medable’s evidence-collection platform is what sets us apart from others in our space.

Taking eCOA technology deployment off the critical path
Within the context of clinical trials, the "critical path" refers to the sequence of activities, tasks, or events that, if delayed or extended, would directly impact the overall timeline for the trial.
These essential steps and dependencies must be completed in a specific order to ensure the trial stays on schedule. Any delay in the critical path can potentially lead to a delay in the entire trial, affecting its completion date and potentially increasing costs. Identifying and managing the critical path is crucial for efficient trial management and timely delivery of treatments to patients.
For a simpler example, take a look at how Monday.com describes the critical path within the context of building a house and their visual aid in Exhibit 2. “For example, if you’re building a house, the critical path might include digging the foundations, building the walls, and installing the roof. If any of these critical activities fall behind schedule the whole project gets delayed.”


Amplifying Evidence with Unified Clinical Trial Data Collection
Join us for a discussion about how combining a unified clinical trial data collection platform with intelligent automation can revolutionize drug development and why the current status quo is no longer sufficient. With novel capabilities, the industry can now explore new possibilities, such as incorporating additional sensors to identify surrogate or alternative endpoints, rethinking adaptive trial designs, and quickly responding to emerging data.
