Clinical Trial Site Selection

Site selection used to depend heavily on networking and manual processes, but targeted strategies and data-driven decision-making are expanding clinical trials to new locations and reaching more diverse populations. However, the human element of site selection remains essential. To participants, sites represent the trial itself, so in-person visits and interviews are necessary to make informed, measured decisions.

 

Steps In Site Selection

The site selection process entails developing criteria based on the protocol, identifying potential sites, and conducting feasibility studies.

Developing Protocol-Specific Site Requirements 

First, researchers use the study protocol to define key site characteristics. This step establishes the desired geographical location, staffing and facility requirements, study duration, and startup timelines. Additionally, researchers determine the participant population and enrollment goals. Researchers must prioritize criteria to ensure that sites have the necessary capabilities to run the trial without unduly narrowing the list of possible sites.

Identifying Potential Sites

Once the protocol-specific criteria are established, researchers identify potential sites using specialized databases, search tools, and professional networks. That initial list should include a variety of sites, including community hospitals, specialized clinics, and primary care facilities.

Conducting Pre-Selection Surveys And Feasibility Assessments 

Potential sites are evaluated through surveys and feasibility assessments. First, sponsors send the primary investigator (PI) an inquiry with a study synopsis and a request for the PI’s CV. If the PI is interested and qualified, the next step is to share the study protocol and provide a detailed survey based on protocol criteria. Meanwhile, sponsors gather and review the site’s enrollment track record, regulatory compliance history, infrastructure, costs, and staff expertise.

These surveys should be unambiguous and produce scorable answers that can be objectively compared and analyzed. Sponsors should consider providing additional support in areas such as good clinical practice (GCP) training or patient recruitment tools for sites that also meet the study criteria.

 

Site Evaluation And Final Selection 

Finally, sponsors evaluate and select the best sites for the trial, then notify the sites and send clinical trial agreements (CTAs) to formalize the partnership.

Leveraging Historical Performance Data 

Historical performance data like patient enrollment, retention, and protocol adherence are examined to evaluate the site. Data from the previous five years and information on ongoing or planned studies in the same field are especially relevant. Normalized metrics compare site performance across trials and study designs, while data-visualization tools highlight high-performing investigators and sites.

Site capacity should also be considered. Highly sought-after sites frequently engage in multiple trials, which could stretch their resources and limit their ability to handle new studies efficiently.

Assessing Regulatory Compliance

Sponsors also evaluate a site’s regulatory compliance track record and look for the following red flags:

• Protocol deviations or missed deadlines
• Adverse findings from past audits
• Inadequate documentation of previous trials
• Poor track record in data submission or patient safety concerns
• Lack of robust patient safety protocols and transparent processes for monitoring adverse events
• Insufficient or outdated data management systems
• Inadequate informed consent procedures
• Conflicts of interest or exploitation of vulnerable populations
• Lack of transparency in contractual arrangements with vendors or other trial participants
• Unclear payment structures, including requests to be paid in different countries or through separate legal entities
• Guarantees of expedited regulatory submissions or patient recruitment without disclosing the approach
• Incomplete or inaccurate medical records
• Missing policies or inconsistent coding practices

Considering Geographical Factors 

Sponsors also should assess a site’s local healthcare infrastructure and any potential site congestion in areas where multiple trials for the same indication are already taking place. For the latter, one option is to consider working with a qualified but research-naïve site. Country and regional trends, as well as cultural and technological factors, also affect site performance. 

Performing On-Site Visits, Investigator Meetings, And Interviews 

The last evaluation stage entails direct interaction with potential sites. In-person visits help sponsors evaluate investigators, staff, facilities, and equipment firsthand to ensure that the site is fully capable of managing the trial.

Clinical Trial Site Activation

Once sites are selected, they undergo the activation process to prepare them to begin enrolling participants and running the study. Site activation can be lengthy, so sponsors should aim to standardize and streamline it as much as possible.

 

Steps In The Site Activation Process 

Site activation is a multi-stage process that prepares the site to meet regulatory and ethical standards, prove financial viability, and create operational readiness.

Regulatory And Ethics Committee Approvals 

Before the study begins, regulatory authorities and ethics committees rigorously review the protocol. In the U.S., the FDA reviews IND applications for drug products, while institutional review boards (IRBs) evaluate the study’s ethics. Criteria include scientific merit, potential risks and benefits to participants, and informed consent procedures. This process can take several months, but regulatory and ethics committee approvals must be granted before enrollment begins.

Contract And Budget Negotiations 

Contract and budget negotiations often run parallel to the regulatory approval process. Sites require funding for personnel, procedures, and overhead expenses, which vary according to the protocol and the site’s cost structure. Sponsors, CROs, and sites work together to negotiate the study’s financial and legal framework, and the resulting CTA details all parties’ responsibilities, intellectual property rights, publication terms, and other trial aspects. Ideally, the relationship is mutually beneficial, with the site receiving adequate support to run the study and sponsors receiving an efficient, timely, and productive trial.

Training And Site Initiation 

Lastly, staff training and site initiation prepare site personnel and infrastructure for the study. Typically, this stage begins after the contract is executed and regulatory approval is secured to ensure the site can safely conduct the trial while maintaining data integrity and regulatory compliance.

The study team is trained in the protocol, GCP guidelines, and study-specific procedures. Typically, sponsors or CROs conduct a site initiation visit to ensure the site is fully prepared to start enrolling participants. They review the protocol, discuss recruitment strategies, and verify that all required equipment, supplies, and documentation are in place. In addition, the site’s data management systems and procedures for managing adverse event reporting are evaluated.

 

Streamlining The Activation Process 

Strategic planning can streamline activation, reducing startup timelines. First, initiating the process during the clinical design stage helps sponsors identify potential bottlenecks and implement mitigation measures, improving resource allocation.

Standardizing and simplifying processes also streamlines activation. SOPs should cover contract negotiation, ethics review, and regulatory submission to minimize back-and-forth communication and reduce errors. Likewise, contracts and budgets can be standardized to accelerate negotiations and CTAs.

Technology such as EDC, CTMS, and e-consent also can improve activation timelines, expedite document collection/review processes, and reduce manual errors.

Clear communication channels for sponsors, CROs, and sites are essential to ensure all parties are informed and aligned. Comprehensive site staff training in the study protocol, procedures, and data management minimizes deviations and errors.

Site staff also need comprehensive training on the protocol and ongoing support. Performance-based incentives and regular updates keep staff engaged in the trial’s success. Sponsors should also meet with sites and investigators regularly to ensure the trial is following the protocol and meets its primary objectives.

 

Budget Optimization Strategies 

Clinical trials significantly increase drug development’s price tag, so budget optimization is crucial to conserving resources. Streamlined study designs and procedures focusing on primary objectives and endpoints can reduce costs. A risk-based monitoring strategy also optimizes resource allocation and reduces on-site monitoring costs. Additionally, choosing sites with successful track records in participant recruitment, retention, and protocol adherence helps sponsors stay on budget.

Expenses should be regularly tracked and managed throughout the trial, and periodic budget reviews can identify areas for cost savings. Finally, alternative funding sources and partnerships with academic institutions or government agencies can provide additional financial support.
