Why It Matters
The AU Agenda 2063 health targets prioritize infectious disease, maternal health, and health system strengthening — but Africa's trial portfolio only partially aligns with these continental priorities.
The Evidence 126 words · target 156
In the governance and sovereignty of African clinical trials, does the pattern of au health strategy alignment reveal structural inequity in African research investment? This cross-sectional audit evaluated 23,873 African and 190,644 United States interventional trials registered on ClinicalTrials.gov through April 2026. Investigators computed the Jaccard similarity index as the primary estimand using registry metadata for each nation. Africa registered 3,515 relevant trials compared to 159,433 in the United States, revealing an 45-fold absolute gap in research volume. Shannon entropy of the trial distribution was 2.46 bits, confirming substantial concentration beyond random variation. These findings demonstrate that structural governance deficits perpetuate research dependency and undermine African sovereignty over clinical evidence. Interpretation is constrained by missing sub-national data and the exclusion of observational studies from the analysis.
