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

How can the process be improved?
Common issues plaguing study conduct• Individual case safety reporting• Event adjudication• Excessive monitoring
![Page 9: Clinical Research and the Importance of Collaboration · HOPE –A large, simple, trial N Pts N Sites N Countries In the beginning (1993) 6,500 130 10But finally (1995) 9,541 267](https://reader034.fdocuments.net/reader034/viewer/2022050103/5f41e29dba2f5a5fa06b4bd4/html5/thumbnails/9.jpg)
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)
![Page 10: Clinical Research and the Importance of Collaboration · HOPE –A large, simple, trial N Pts N Sites N Countries In the beginning (1993) 6,500 130 10But finally (1995) 9,541 267](https://reader034.fdocuments.net/reader034/viewer/2022050103/5f41e29dba2f5a5fa06b4bd4/html5/thumbnails/10.jpg)

Streamlining: Adjudication
![Page 11: Clinical Research and the Importance of Collaboration · HOPE –A large, simple, trial N Pts N Sites N Countries In the beginning (1993) 6,500 130 10But finally (1995) 9,541 267](https://reader034.fdocuments.net/reader034/viewer/2022050103/5f41e29dba2f5a5fa06b4bd4/html5/thumbnails/11.jpg)
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)
![Page 12: Clinical Research and the Importance of Collaboration · HOPE –A large, simple, trial N Pts N Sites N Countries In the beginning (1993) 6,500 130 10But finally (1995) 9,541 267](https://reader034.fdocuments.net/reader034/viewer/2022050103/5f41e29dba2f5a5fa06b4bd4/html5/thumbnails/12.jpg)

Streamlining: Monitoring

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)
![Page 14: Clinical Research and the Importance of Collaboration · HOPE –A large, simple, trial N Pts N Sites N Countries In the beginning (1993) 6,500 130 10But finally (1995) 9,541 267](https://reader034.fdocuments.net/reader034/viewer/2022050103/5f41e29dba2f5a5fa06b4bd4/html5/thumbnails/14.jpg)

Collaborating to resolve fundamental clinical trialissues
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

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!
