Clinical trials form the backbone of modern drug development and are critical for ensuring that new therapies are safe, effective, and able to reach patients in need. Clinical trials are complex endeavors and hence, behind every successful trial is a team of dedicated professionals responsible for its smooth execution. One of the most critical amongst these team members are Clinical Research Associates (CRAs) who form the vital link between sponsors, CRO, and clinical research site staff.
The clinical research industry continues to expand rapidly and according to Grand View Research, the global clinical trials market was valued at over $69 billion in 2022 and is anticipated to grow steadily in the coming years 2. With oncology alone accounting for more than 30% of all ongoing clinical trials, the demand for expert oncology monitoring and high-quality clinical trial monitoring services has never been higher. This growth and associated demand places CRAs and their role firmly at the center of trial success.
In this article, we shall explore the responsibilities, skills, and evolving role of CRAs, and highlight how Palleos, a leading full-service CRO, supports sponsors with top-tier CRA services and CRO solutions.
A CRA’s responsibilities span across the entire clinical trial lifecycle all the way from study start-up to close-out. Each task they oversee or perform directly impacts patient safety, data quality, and regulatory compliance. Some of these responsibilities include:
CRAs actively participate in initiating clinical trial sites based on factors such as patient population, site infrastructure, efficacy endpoints and investigator experience. During initiation visits, they ensure staff are trained on the protocol, adhere to regulatory guidelines, informed consent process, and study systems.
Why it matters: Proper site initiation reduces protocol deviations, ensures staff readiness, and creates the foundation for high-quality data collection.
The core of CRA work involves routine monitoring visits, either physical on-site visits or remote coordination. CRAs review source documents, verify and ensure accuracy of the data entered into the Electronic Data Capture (EDC) system, and confirm adherence to Good Clinical Practices (GCP) and International Council for Harmonization (ICH) guidelines.
Why it matters: Monitoring ensures that patient safety is safeguarded, adverse events are accurately reported, and trial data remains valid for submission to regulatory authorities.
CRAs work closely with site staff to reinforce protocol requirements and provide ongoing training. They help resolve questions about dosing schedules, eligibility criteria, endpoint measurements and reporting obligations.
Why it matters: Protocol deviations can compromise patient safety, skew data, or even invalidate a study. Any deviation from the protocol or regulatory guidelines can result in an FDA hold on the trials resulting in substantial financial losses 3. By supporting and empowering site teams, CRAs help trials remain compliant and credible.
CRAs ensure that essential documents such as ethics committee approvals, informed consent forms, institute review board (IRB) coordination and regulatory submissions are accurate and up to date.
Why it matters: Inaccurate or incomplete documentation can delay approvals or lead to regulatory holds. CRAs uphold compliance across local regulations as well as international standards.
CRAs act as problem-solvers, addressing site challenges such as recruitment delays, data discrepancies, site coordination issues, or equipment problems. They serve as the primary communication channel between sponsors and site teams.
Why it matters: Timely resolution of problems minimizes trial disruptions, keeps studies on track, and ensures smooth collaboration across stakeholders.
CRAs balance scientific knowledge, regulatory expertise, project management and interpersonal skills. The best CRAs excel in:
The CRA role is evolving alongside advances in digital technology and decentralized trial models 4. Here’s what the future looks like:
