Contributor list

The PeRSEVERE project has been initiated and led by Will Cragg, Regulatory and Governance Affairs Manager & Methodology Lead for Trial Conduct at the Clinical Trials Research Unit, University of Leeds.

Many others have helped with the project at different stages. See below details of project steering group members, contributors to the writing groups (which drafted the original PeRSEVERE principles), and other key project contributors.

The PeRSEVERE project steering group is also very grateful for the contributions of others not mentioned here, including others who have contributed to wider discussions on the topic of withdrawal of consent in clinical trials, and all those who took time to provide their feedback via our public consultation.

We are also indebted to the UKCRC Registered Clinical Trials Unit Network, including the Executive Group, Programme and Delivery Manager, and Senior Administrative Assistant, for their support.
