Co-creation of practical "how-to guides" for patient engagement in key phases of medicines development-from theory to implementation.

Background: The effective impact of patient engagement (PE) across the medicines development continuum is widely acknowledged across diverse health stakeholder groups, including health authorities; however, the practical applications of how to implement meaningful and consistent PE are not always addressed. Guidance for the practical implementation of PE requires granularity, and the need for such guidance has been identified as a priority. We describe the co-production and summarize the content of how-to guides that focus on PE in the early stages of medicines development.
