Key characteristics of (most) PHRI studies • Scientifically interesting question • Collaborate with National Leaders: • Expert trialists ’ and not just key opinion leaders • Member of the Steering Committee • Involved in developing protocol, CRFs, study procedures www. phri .ca

How can the process be improved? Common issues plaguing study conduct • Individual case safety reporting • Event adjudication • Excessive monitoring www. phri .ca

Streamlining: Safety Reporting • First studies to use the triple “and” - serious and unexpected and associated • National Leaders defend approach: • Locally (ethics) • Nationally (regulatory bodies) www. phri .ca

Streamlining: Adjudication www. phri .ca

Event Adjudication • No effect on study outcomes/conclusions • Is it worthwhile? How can we streamline? • Use event definitions that closely resemble usual practice • Only adjudicate those events which don’t meet the criteria • Ask National Leaders to adjudicate (in local language) www. phri .ca

Streamlining: Monitoring www. phri .ca

Monitoring • Risk based approach • Used in APOLLO (2011), HOPE-3, TIPS-3 and COMPASS • Implemented through National Leader’s office • ADAMON study (2017) showed risk-based monitoring was non-inferior to extensive monitoring • At best, on site may reduce major GCP findings by 8% • Congruent with recent ICH E6 R2 (revision) www. phri .ca

Collaborating to resolve fundamental clinical trial issues 2007 – Duke, Oxford and PHRI organize the first Sensible Guidelines meeting • Academics, regulators, industry sponsors invited • Objective is to identify biggest barriers to trial conduct • 8 publications 2009 , 2012 Repeat Workshops 2017 ICH E6 modified www. phri .ca

Which led to other initiatives • Initiatives to Streamline Clinical Trials – Canada • India – Efforts with DCGI • MoreTrials (http://moretrials.net) www. phri .ca

Collaboration: Low & middle income countries • INTERHEART, INTERSTROKE, INTERBLEED • PURE (~180,000) • IMPI (Investigation of the Management of Pericarditis) • No effective treatment for TB pericarditis: Anti- inflammatory may work • Collaboration with University of Cape Town, Bongani Mayosi, Mpiko Ntsekhe www. phri .ca

Collaboration today.. Necessary for: • Detecting modest but worthwhile treatment effects • Accurate estimates of treatment effects across different ethnicities and health care systems • Efficient knowledge translation Progressive • Two way street And it is an incredibly rewarding experience! www. phri .ca
