The Challenges and Rewards of Recruiting Participants for Clinical Trials in Low- and Middle-Income Countries (LMICs)
A Global Health Crisis Demands Innovative Solutions
In the fight against infectious diseases, particularly tuberculosis (TB), the world turns to clinical trials for potential vaccines. But conducting these trials in LMICs presents unique challenges and opportunities.
The Urgent Need for TB Vaccines
TB, the world's deadliest infectious disease, has only one vaccine, BCG, which offers limited protection against pulmonary TB in adolescents and adults. This is a critical gap, as these age groups bear the highest burden of the disease and are the primary transmitters. At Gates Medical Research Institute (Gates MRI), we're developing the M72 vaccine to address this gap.
Recruitment: The Key to Success
Participant recruitment is a critical aspect of clinical trials, and in LMICs, it involves a delicate balance of urgency and respect. We must respond to the community's needs while ensuring they understand the aims and their role in the research.
Strategies for Success in the M72 Trial
Our M72 Phase 3 clinical trial, a massive undertaking across 54 sites in Indonesia, Kenya, Malawi, South Africa, and Zambia, required innovative recruitment strategies. Here's how we did it:
1. Advance Work: Identifying Hotspots
TB primarily affects LMICs, so we conducted an epidemiological study across 14 countries and 45 sites. This study helped us identify TB hotspots and prepare clinical sites. By understanding the disease burden, we could focus our efforts where they were needed most.
2. Building Trust: Community Engagement
Community outreach is about more than recruitment; it's about building long-term relationships. We engaged with a global community advisory board, presenting our program and listening to their feedback. Local trial sites also involved community leaders, advisory boards, and health workers from the start. This approach ensures that the community feels heard and invested in the research.
3. Leveraging Local Partnerships and Expertise
Collaborating with local healthcare providers, such as TB clinics, helped us identify and reach high TB burden communities more effectively. The epidemiology study we conducted ahead of the M72 trial allowed us to assess and improve our infrastructure and support services, ensuring a smooth process for the upcoming trial.
The Impact of Community Collaboration
Clinical trials are not isolated events; they are a collaboration with the community that extends beyond the trial's lifespan. By involving the community in design and recruitment, we foster a sense of ownership and trust. This approach is critical to the success of our research and the well-being of the communities we serve.
