How Clinical Site Operations Work
Clinical sites are where studies are conducted, often in hospitals, private clinics, or specialized research facilities. These sites are responsible for recruiting participants, collecting data, and ensuring the trial is executed per protocol and regulatory standards.
1. Study Feasibility and Site Selection
Before a site is selected, it has to go through a few steps. First, the site would assess if a study is feasible for the site based on resources, patient demographics, and expertise. Sometimes the protocol can be too stringent for a particular site to be successful in a study, so it becomes important for both the site and the sponsor to review if the relationship would be a good fit for the proposed study.
2. Contract and Budget Management
Typically, the finance and legal team at the site level will collaborate with sponsors or CROs to finalize budgets and contracts. These teams will track and ensure timely payments from sponsors are made for all completed trial activities.
3. Regulatory Compliance
The regulatory team will work with the sponsor and the CRO to prepare and submit study protocols, informed consent forms, and other required documents to the IRB (Institutional Review Board) or Ethics Committee (EC) as necessary. They also provide sponsors and CROs with requested documents in the trial process. The site also maintains essential documents such as training records and delegation logs in the regulatory binder at all times.
4. Patient Recruitment and Retention
Once the clinical trial begins, the site pursues various recruitment strategies to ensure study goals are met while maintaining the integrity of the study and adhering to all regulatory guidelines. The study team will develop and implement strategies to identify eligible participants. These strategies include advertising using flyers and community outreach. Many sites create an internal list of potential people interested in participating in a study. Reaching out to these people and being available to clarify any questions they may have is crucial. When retaining participants, it also becomes important to ensure they are engaged through regular follow-ups, clear communication, and addressing concerns.
5. Study Start-Up Activities
One of the important steps in the study’s start-up is the site initiation Visit (SIV). SIVs are when the CRO or the sponsor will facilitate site initiation meetings to review study protocols, procedures, and sponsor expectations. This is a great meeting to take in-depth notes and gather questions to ask. The CRO or sponsor may also choose to train site personnel on protocol requirements, GCP, and any study-specific tasks.
6. Clinical Trial Conduct
When it comes to the study staff performing the clinical trials, the three main components are screening and enrollment, informed consent, and study visits. During the screening and enrollment process, the study staff will identify and enroll eligible participants based on the inclusion and exclusion criteria. It is extremely important to ensure participants fully understand the study and provide clear, documented consent. Once that is completed, the study staff can perform the study visits based on the protocol. The visits may include assessments, procedures, randomization, and data collection.
7. Data Collection and Management
During the visit, all data must be collected properly and should be accurately documented in the Case Report Forms (CRFs). Some sites opt in for the electronic CRFs. The data in the source documents (CRFs) should match the data entered into the EDC. If the site has a separate team to transcribe data into the EDC, it’s important to double-check to ensure the accuracy and quality of the data are maintained and consistent. If the CRO or sponsor raises any data queries or even the internal quality assurance team, it’s important to resolve any discrepancies and respond to the raised queries in a timely manner.
8. Investigational Product (IP) Management
When there is an IP (drug) involved, it must be stored per protocol at the required temperatures. When these IP drugs are dispensed to the subjects/participants, the distributions must be tracked and maintained in accurate logs. Typically, the sponsors provide these logs. Just like dispensing, any returns or destruction of these IPs must also be tracked and managed by coordinating with the sponsors.
9. Monitoring
The sites will host sponsor or CRO monitoring visits for regular checks on data quality, compliance, and progress. Some sponsors or CROs prefer remote visits while others prefer physically coming to the sites. During these visits, the monitor will inform the site of their findings as needed.
10. Participant Safety and Adverse Event (AE) Reporting
It’s important to conduct regular assessments to monitor participant health. If something seems out of the norm, the study staff must report to the responsible parties immediately. If it looks like it is an adverse event (AE) or a serious adverse event (SAE), these should be reported to the sponsor, IRB, or regulatory authorities as required.
11. Communication and Collaboration
As the study team, it’s important to provide regular updates on trial progress and address sponsor/CRO requests. The study team should be all over their emails and address any inquiries on time. Additionally, the study team should also coordinate regularly with physicians, nurses, lab technicians, and other site staff for smooth operations.
12. Logistics and Operational Support
The site staff must ensure that all equipment like freezers, ECG machines, and centrifuges are working properly, calibrated, and are available for use when needed. If the shipments require ice packs, cold packs, or dry ice, freezers, and refrigerators should be stocked accordingly. Also, the site staff should ensure there are enough supplies available and order if they are running low. There should also be a dedicated space for study binders and a separate space for lab sample handling.
13. Close-Out Activities
When the study is closing, there is a COV (close-out visit) conducted to ensure all data and IP are accounted for. If there is a PD (Protocol Deviation), the site will have to address that before closing. All data and files must be organized and secured for the retention period. This is based on the sponsor and how long you need to retain the documents. GCP and regulatory guidelines also play a role in this.
14. Continuous Improvement
The study team might have an internal meeting after the close out to discuss any feedback and refine any processes based on learnings and apply them to future studies. The site will also ensure all staff is updated on regulatory changes, new technologies, and the company’s best practices.
Overall, patient safety is above everything. A good clinical site’s operation is the backbone of successful clinical trials as they perform their studies ethically, follow all regulatory guidelines, and continue learning from any mistakes.
