The Challenges and Strategies of Participant Recruitment in LMIC Clinical Trials
A Global Health Crisis: Tuberculosis and Beyond
Tuberculosis (TB) is a deadly infectious disease that continues to claim millions of lives each year. Despite its devastating impact, especially in low- and middle-income countries (LMICs), there is only one vaccine available, BCG, which has its limitations. This stark reality highlights the urgent need for innovative solutions and effective vaccines.
The Gates Medical Research Institute (Gates MRI) Steps In
At Gates MRI, we are dedicated to addressing global health threats, particularly TB and malaria. Our mission is to develop vaccines that can prevent these diseases and save lives. One of our key projects is the M72 vaccine, designed to prevent pulmonary TB in adolescents and adults, who bear the brunt of this disease.
The Importance of Participant Recruitment
Participant recruitment is a critical aspect of any clinical trial, and it becomes even more complex and nuanced in LMICs. The high burden of infectious diseases in these regions creates a sense of urgency and relevance for vaccine trials. People in LMICs often have personal connections to those affected by diseases like TB, which motivates their participation.
But here's where it gets controversial...
While this motivation is a powerful force, it also presents ethical considerations. It's crucial to ensure that participants fully understand the aims of the trial and their role in it. This is where community engagement and trust-building become essential.
Building Trust and Collaboration
At Gates MRI, we recognize that participant recruitment is not just about numbers; it's about building long-term relationships and fostering a sense of shared ownership. We engage with communities, involving local leaders, advisory boards, and health workers from the very beginning. This approach ensures that we address any concerns and work together towards a common goal.
For instance, in the M72 study, we established community advisory boards (CABs) at most trial sites. These CABs, similar to our global board but with a local focus, played a vital role in shaping our recruitment strategies and ensuring community involvement.
The Power of Local Partnerships
Collaboration with local healthcare providers, such as TB clinics, is another key strategy. By working together, we can more effectively identify and reach communities with a high burden of TB. This approach not only improves our recruitment efforts but also strengthens the local healthcare infrastructure.
And this is the part most people miss...
The epidemiology study we conducted before the M72 trial was not just about identifying TB hotspots. It was an opportunity to test and improve our intake procedures and ensure that our clinical sites were well-prepared. This study allowed us to provide valuable hands-on experience to our sites, giving them a head start for the upcoming M72 Phase 3 trial.
The Bigger Picture
Clinical trials are not isolated events; they are part of a larger ecosystem. Participant recruitment is the gateway to a long-lasting collaboration with the community, which extends beyond the trial's lifespan. It's about building trust, improving healthcare, and ultimately, saving lives.
