ABSTRACT
OBJECTIVES:
To review the pragmatism of published randomized trials of remdesivir and favipiravir based on the Pragmatic-Explanatory Continuum Indicator Summary (PRECIS-2) framework. STUDY DESIGN ANDSETTING:
Ten eligible trials were identified from an existing comprehensive living review and were evaluated across the nine PRECIS-2 domains by two independent reviewers.RESULTS:
All 10 trials had mostly pragmatic design characteristics. Four of the domains (i.e., recruitment, setting, organization, and primary analysis) were found to be pragmatic with most trials scoring four or five across the two interventions. In comparison scores for four other design domains (i.e., eligibility, follow-up, flexibility of delivery, and primary outcome) varied across the trials with some design choices being more explanatory.CONCLUSION:
In our descriptive review of randomized controlled trails for two drugs for patients infected with COVID-19 early in the pandemic, we found that most trials had more pragmatic than explanatory characteristics. Some design choices for some of the trials, however, were not consistent with the urgent goal of informing clinical decision making in an epidemic. PRECIS-2 should be used as a guide by trialists, to help them match their trial design choices to the intended purpose of their trial.
