Why It Matters
India, China, and Brazil are emerging as alternative research partners for Africa, potentially disrupting the traditional North-South axis of clinical trial sponsorship.
The Evidence 130 words · target 156
In the governance and sovereignty of African clinical trials, does the pattern of south-south collaboration index 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 ARIMA-forecast trend as the primary estimand using registry metadata for each nation. Africa registered 1,444 relevant trials compared to 5,486 in the United States, revealing an 4-fold absolute gap in research volume. Temporal analysis showed 17.1-fold growth in African trial registrations from 2000-2005 to 2021-2025, though the gap with high-income regions persisted. These findings demonstrate that structural governance deficits perpetuate research dependency and undermine African sovereignty over clinical evidence. Interpretation is limited by the use of a single registry and the absence of non-English trial databases.
