New Research Statement Recommends Streamlining and Standardizing Clinical Trial Site Feasibility Assessments

Get Permission

Feasibility assessments for clinical trials are conducted to establish that prospective trial sites can safely and effectively meet study goals and protocol requirements; however, a new research statement from ASCO asserts that current standards are “costly, inconsistent, inefficient, labor intensive, and of uncertain effectiveness.” These deficiencies ultimately result in fewer patients with timely access to clinical trials and delays in advancing novel safe and effective treatments.

The research statement, which was published in JCO Oncology Practice,1 provides concrete recommendations to improve the effectiveness and efficiency of the feasibility assessment process to ensure that more trial sites and patients can participate in oncology clinical trials. These recommendations also help address a goal established in ASCO’s Road to Recovery Report to simplify, streamline, and standardize clinical trials.

The following recommendations were developed through an ASCO task force and incorporate feedback from stakeholders including trial sites, biotech-pharma sponsors, and contract research organizations. The recommendations were approved by ASCO’s Board of Directors.

Streamlining Feasibility Assessments

During the typical feasibility assessment process, sponsors and contract research organizations assess the ability of a site to conduct clinical trials and implement specific trial protocols. The feasibility assessment process typically includes completion of a comprehensive and lengthy site feasibility questionnaire and an in-person prestudy site visit prior to selecting the site for a trial.

“Stakeholders who participated in this initiative described existing site feasibility methods as burdensome, inefficient, time-consuming, redundant, and resource intensive. They also reported that the process causes delays in time to enrollment and affects the capacity for sites to participate in clinical trials, particularly smaller research programs with limited resources and infrastructure,” the authors write.

ASCO recommends the implementation of a streamlined and uniform feasibility assessment process for use by all trial sponsors and contract research organizations. Feasibility assessments should be conducted in one of the three ways: (1) a short feasibility questionnaire and a prestudy site visit; (2) a long feasibility questionnaire alone (no prestudy site visit); or (3) a prestudy site visit or teleconference alone (no feasibility questionnaire). All stakeholders identified benefits with the recommended process changes, including time savings, expedited start-up, reduction in personnel resources, and cost savings.

In addition to recommended process changes, the research statement also outlines best practices for sponsors, contract research organizations, and trials sites to adopt to improve efficiencies throughout the feasibility assessment process. For example, each organization should consider establishing standard operating procedures, designating a single point of contact, and conducting as much of the process as possible remotely. Trial sites should also consider maintaining a standardized site capabilities document to share with sponsors and contract research organizations.

Minimizing Questions

Questions asked through feasibility questionnaires and prestudy site visits are often redundant and highly variable across sponsors and contract research organizations. ASCO recommends sponsors and contract research organizations standardize feasibility assessment questions with common nomenclature, questions, and response options. Feasibility assessment questions should also be kept to the minimum necessary (ie, need-to-know) and focus on two factors: (1) site capability to conduct clinical trials and (2) specific protocol feasibility.

Minimizing and standardizing feasibility assessment questions would save sites a significant amount of time and effort and would help them respond with accurate and consistent information.

Centralizing Information Exchange

ASCO recommends all sites, trial sponsors, and contract research organizations use a universally accessible and accepted database and portal to centralize feasibility assessments, improve efficiencies, and expedite clinical trial start-up. The database should be a Web-based portal that can integrate as seamlessly as possible into clinical and research staff workflows.

The research statement acknowledges existing portals have limitations and/or are not widely used, and competition among sponsors, contract research organizations, and vendors might make agreement on a single portal unlikely in the near future. In the absence of a portal, sites, sponsors, and contract research organizations should use a universal and standardized site profile and capabilities form to more efficiently share information.

“All stakeholders stand to benefit from implementing these recommendations,” the authors write. “To have meaningful impact, adoption and consistent execution of these recommendations across all trials, sponsors, contract research organizations, and sites are essential.
