Guidance for best practices for clinical trials

This document responds to requests by the World Health Assembly to the Director-General in resolution WHA75.8 (2022) on strengthening clinical trials to provide high-quality evidence on health interventions and to improve research quality and coordination to identify and propose best practices and other measures to strengthen the global clinical trial ecosystem and to review existing guidance and develop new guidance as needed on best practices for clinical trials. This guidance updates and adapts the previous work of the World Health Organization (WHO) on research capacity for the context of well-designed and well-implemented clinical trials as framed in resolution WHA75.8 (2022). It aims to enhance clinical research efficiency, minimize research waste and provide guidance on sustained clinical trials that are always functional and active for endemic conditions and can pivot in time of emergency or pandemics.
