The TB Practecal trial’s Project Management Team, housed in the Manson Unit at MSF UK, manages the project on a day-to-day basis, overseen by a strong governance structure including a Steering Committee and an external Scientific Advisory Committee consisting of world-renowned experts.

An external and independent Data and Safety Monitoring Board also ensure that the highest standards in patient safety and data reliability are met.


Ethics Oversight

Independent Ethics Review Boards (ERBs) are charged with protecting the rights, safety and wellbeing of clinical trial participants.

They review all aspects of a study before deciding whether it can go ahead or not. Before a site is allowed to start enrolling patients, the ERB will review all study-related materials including the protocol, standard operating procedures and patient materials. ERB’s also perform periodic reviews throughout the study’s duration.

TB Practecal is being reviewed by the following independent Ethics Review Boards (ERB):
