Challenges of sharing individual participant data for secondary research on neglected tropical diseases: the experience of Drugs for Neglected Diseases initiative and a call for action.

Introduction: The Drugs for Neglected Diseases initiative (DNDi) is committed to maximising the scientific value of the individual participant data (IPD) it has collected during its 20 years of activity and the IPD it will collect in the future, while safeguarding research participants' privacy and their right to know how their data will be processed.

Objective: The objective of this article is to share what DNDi has learnt while working on its commitment to data sharing. It also aims to advance the debate about best practice in the research community to avoid 'IPD sharing paralysis', with a focus on multistakeholder projects involving patients and researchers based in countries with various levels of data privacy regulations and measures.
