The Study Coordinator is a key figure in the operational conduct of clinical trials at the site level. They serve as the organizational interface between the study site and the sponsor or the CRO. The coordinator is responsible for the organizational, administrative, and logistical coordination of all study activities at the site and works in close collaboration with the Principal Investigator (PI), sub-investigators, and the Clinical Research Associate (CRA) of the sponsor organization or CRO. In many study centers, the Study Coordinator is the primary point of contact for study participants and the operational backbone of trial management at the site level. Their work is closely linked to the requirements of Good Clinical Practice (GCP) and is regularly reviewed during monitoring visits and GCP inspections.
Tasks and responsibilities
The scope of duties for a Study Coordinator is broad and encompasses both administrative and clinical-operational activities. Central tasks include: the organization and scheduling of study visits, the management and archiving of study-relevant documents in the Investigator Site File (ISF), the preparation and follow-up of monitoring visits, and the support of study participants throughout the entire study process.
In the area of data management, the Study Coordinator is often responsible for the entry and maintenance of data in the electronic Case Report Form (eCRF), the timely resolution of data queries, and the archiving of source documentation. They coordinate the logistics of the investigational medicinal product (drug accountability), support the investigator with SAE reporting, and ensure that informed consent forms are correctly documented.
Qualification and Training
Study Coordinators often have a nursing or medical-technical background, and increasingly possess scientific or clinical trial specializations. Basic knowledge of GCP is a prerequisite; many study centers require current GCP training according to ICH E6(R3) as a minimum qualification. International certifications such as ACRP (Association of Clinical Research Professionals) or SOCRA (Society of Clinical Research Associates) strengthen the professional profile.
Before the start of any study, the Study Coordinator must be briefed on the study protocol, the sponsor’s SOPs, and specific study requirements during a Site Initiation Visit (SIV). This training must be documented and recorded in the delegation log of the ISF. The PI is responsible for the supervision and appropriate delegation of tasks to the Study Coordinator. For multicenter studies, CROs often organize central remote training or certified online training to ensure uniform training quality across all sites. Supplementary study-specific training on special procedures—e.g., biological sample collection, special measurement instruments, or electronic consent processes (eConsent)—must also be documented in the ISF.
Delegation and GCP Requirements
According to ICH E6(R3), the PI may delegate study-relevant tasks to qualified personnel. Delegation is performed via the Study Delegation and Signature Log, which records all study staff, including the Study Coordinator, along with their delegated tasks, qualifications, proof of training, and signature samples. Any change in the study team must be updated promptly in the delegation log.
The Study Coordinator is not permitted to make medical decisions that are reserved for the Principal Investigator—including the assessment of a patient’s eligibility for the study, the obtaining of informed consent, or the clinical evaluation of adverse events. This distinction is clearly defined by regulation and is specifically verified during GCP inspections and monitoring visits.
Importance for Study Quality
The quality of a Study Coordinator’s work has a direct impact on data quality and compliance with the study protocol. A well-trained and experienced Study Coordinator reduces the rate of protocol deviations, improves the quality of source documentation, and ensures complete and timely SAE documentation. Studies with experienced Study Coordinators generally show fewer findings during GCP inspections. Regular internal quality checks by the Study Coordinator—e.g., weekly ISF reviews, eCRF completeness checks, and query aging controls—are a proven practice for proactive quality assurance at the site level.
For full-service CROs like mediconomics, the early identification of qualified Study Coordinators at potential study sites is an important component of the site feasibility assessment. In the coordination of multicenter studies, uniform training measures and clear communication structures between the CRA, sponsor, and Study Coordinator are crucial for the success of the study.
Frequently Asked Questions (FAQ)
What is the difference between a Study Coordinator and a Clinical Research Associate?
The Study Coordinator works at the study site and coordinates local study conduct on behalf of the Principal Investigator. The Clinical Research Associate (CRA) is usually employed by the sponsor or the CRO and visits the sites for monitoring purposes. The CRA monitors compliance with the protocol and GCP requirements from the outside, while the Study Coordinator ensures the daily operational study work on-site.
Does the Study Coordinator have to complete GCP training?
Yes. According to ICH E6(R3), every member of the study team who undertakes study-relevant tasks must have documented GCP training. The training must be current for the respective study and must be noted in the delegation log. Many sponsors require training that is no older than 2–3 years. Regular refresher training is considered best practice.
What happens if a Study Coordinator leaves the site?
A change in Study Coordinator must be reported to the sponsor immediately. The delegation log must be updated, and the new Study Coordinator must be fully trained before independently performing study tasks. All documents from the departing coordinator remain in the ISF. In the event of an unplanned staff change, the CRA may conduct an unscheduled monitoring visit to ensure the continuity of study activities.
