Global Imbalances in Funding Sources for HIV Randomized Control Trials.

Abstract

Improving access to grant funding is a critical aspect of strengthening research capacity outside of higher income settings, particularly in HIV/AIDS where randomized control trials (RCTs) that require substantial resources are common. In this article, we assessed recent RCTs to examine variation in how studies were funded, depending on study location and the countries where publication authors were based. We conducted a PubMed literature review to identify RCTs with HIV status or viral load endpoints published in 2019 and 2020, then analyzed cross-tabulations of funding sources by study characteristics. One hundred sixteen publications met the inclusion criteria. Research in higher income countries was most likely to be funded by biotech/pharmaceutical companies, whereas research in lower- and middle-income countries was most likely to be funded by U.S. government sources. Overall, we found the distribution of funding sources differed significantly by study and author location (χ2 = 23, p < .001). Published RCTs with HIV status or viral load endpoints are financed differently based on where studies take place and where the authors are based. As part of future research, understanding why this variation exists is critical for assessing how funding contributes to global imbalances in scientific resources.
