It Worked in the Trial but No One Will Take It Improving Methods for Moving from Clinical Trials into the Real World Manya Magnus, PhD, MPH Professor | Associate Chair Department of Epidemiology Milken Institute School of Public Health George Washington University I would like to extend my thanks to the organizers for including me in this exciting panel. In the next 10 minutes I would like to identify a key challenge in moving effective treatments to scale and offer a potential methodologic solution.

Pre-clinical drug development Phase I, II, III clinical trials
FDA review Success! The Drug WORKS and is approved for use -Policy and program changes -Demonstration projects -Implementation science Identification of challenges and innovation surrounding removal of barriers Eventually successful implementation and realized outcomes (But many years post-approval) Purpose of this talk is to identify common barriers to moving from discovery to scale up, and to suggest reorganizing our conceptualization about where implementation science methods belong in the drug development process. First let’s talk about how this usually works: Note this is for US drug development but similar for EMA. After 9-14 years of drug development, plus additional ~2 for review, we waiting for a drug that we know works – and this can apply to prevention, treatment, eventually cure. How can we reduce the time from approval to successful implementation and scale up of a medication? Approximately 9 to 15 years1

PrEP in US as an example Since 2012: Pre-2012
Studies to examine populations inadequately included in iPrEX2,3,4 Implementation science studies to decrease barriers and increase adherence (e.g., technology) Continued poor PrEP delivery to those at highest risk of HIV and payor structures slow to resolve Mistrust, stigma, provider barriers, structural barriers to PrEP and other prevention services care3,4,6,7 Success! 2012 TDF/FTC to prevent HIV and is approved for use by FDA Eventually successful implementation and realized outcomes

There Remains Disproportionate PrEP Use
Men and 25- to 44-year olds were more likely to be PrEP users 8 93% of all PrEP users in 2016 were male Geographic differences 8 Nearly 50% of PrEP users in 2016 were located in five states: New York, California, Florida, Texas, and Illinois The South has the highest number of new HIV diagnoses in the U.S. but disproportionately fewer people using PrEP MSM at greatest risk are Black and Latinx yet least likely to receive PrEP 3,4,5,8 With 2017 guidelines, 1.23 million adults at risk for HIV acquisition for whom PrEP and other prevention methods are indicated from 25% in 2015 to 45%9,10
6
What are the challenges and barriers?
Generalizability Clinical trials population does not reflect real world Structural barriers Cost and accessibility Stigma Political will Providers Adherence Real world issues in adherence Physical challenges (e.g., side effects) Fatigue Knowledge of importance Acceptability of regimen What are the challenges and barriers? As I am both a clinical trials person and a structural barriers person, this gives me the opportunity to consider how and why this considerable delay is occurring. In order to shrink this timeline from drug approval to effective scale up we need to move more rapidly from studies of efficacy in ideal situations to effectiveness in the real world situations. Similar for all HIV medications
7
What Can We Do?
8
Shortening the Timeline from Discovery to Implementation
The barriers are not a mystery All treatment, prevention, cure strategies are likely to have the same challenges We know what the issues are Generalizability in trial samples Identification of and proactive removal of expected structural barriers simultaneous with implementation Including studies to elucidate these and identify solutions Adherence
9
Solution: We need to move from sequential to simultaneous
Implementation science concomitant with clinical trials Collaboration of multi-disciplinary investigators – remove siloes Increasing examples of this (e.g., CAB LA development program), but we can do more Address cost and access issues in studies (policies and barriers) Improve understanding of challenges with adherence Learn what they are from both clinical trial and community-based samples simultaneously Develop, deploy, and measure adherence strategies at the same time as study drug rollout - not after Make innovations that focus on the root causes and not just the app/vendor/etc. methods for identifying what will be successful Positive changes: 083 composition of sample, in trial + community studies on acceptability of injectables,

What might implementation look like with this approach?

The Drug WORKS and is approved for use, and methods
Pre-clinical drug development Phase I, II, III clinical trials FDA review -Policy and program changes -Demonstration projects -Implementation science Identification of challenges and innovation surrounding removal of barriers Success! The Drug WORKS and is approved for use, and methods to overcome barriers deployed at same time as initial drug launch Subsequent implementation science approaches to refine rather than create ways to scale up to communities Successful implementation and realized outcomes (Nearly simultaneous with approval)
19
Conclusions Urgent need to develop methods that decrease time from drug discovery to scale-up and implementation Improvement of methods and integration of implementation science concerns into clinical trials Especially critical for populations at greatest risk of not accessing medication While barriers to effective scale up may vary by location or sub-population, what we need to examine does not, making it possible to be proactive Simultaneous rather than sequential application of methods is critical Generalizability of sample Addressing structural barriers Overcoming eventual barriers to adherence For HIV especially, the issues are unlikely to differ by drug allowing us to start earlier in the process
