N1 - Funding Information:
The MERIT trial is being financially supported by the US Department of Defense Peer Reviewed Medical Research Program (W81XWH1810742 to A.A.R.T). The sponsor does not have a role in the study design; collection, management, analysis, or interpretation of data; writing of the manuscript; or decision to submit the manuscript for publication. The US Army Medical Department Board (AMEDD) is assisting in evaluating medical devices, materials, and products for the US Army. The NIH National Institute of Allergy and Infectious Diseases Office of Cyber Infrastructure and Computational Biology is providing support for data management. In addition, the HHV-8 testing is supported in part with federal funds from the Frederick National Laboratory for Cancer Research, under contract number HHSN261200800001E and NCI contract 75N91019D00024. TQ is supported by the Division of Intramural Research, National Institute of Allergy and Infectious Diseases (NIAID). We also appreciate that Terumo BCT is providing the equipment and disposables as a donation to the trial. The funders did not play a role in the study design, decision to publish, or preparation of the manuscript.
Funding Information:
This trial would not be possible without the dedication of the study participants. We also appreciate the support of the study staff and the UBTS blood bank, as well as the careful ongoing reviews by the Data Safety Monitoring Board.

N2 - Background: Transfusion-transmitted infections (TTIs) are a global health challenge. One new approach to reduce TTIs is the use of pathogen reduction technology (PRT). In vitro, Mirasol PRT reduces the infectious load in whole blood (WB) by at least 99%. However, there are limited in vivo data on the safety and efficacy of Mirasol PRT. The objective of the Mirasol Evaluation of Reduction in Infections Trial (MERIT) is to investigate whether Mirasol PRT of WB can prevent seven targeted TTIs (malaria, bacteria, human immunodeficiency virus, hepatitis B virus, hepatitis C virus, hepatitis E virus, and human herpesvirus 8). Methods: MERIT is a randomized, double-blinded, controlled clinical trial. Recruitment started in November 2019 and is expected to end in 2024. Consenting participants who require transfusion as medically indicated at three hospitals in Kampala, Uganda, will be randomized to receive either Mirasol-treated WB (n = 1000) or standard WB (n = 1000). TTI testing will be performed on donor units and recipients (pre-transfusion and day 2, day 7, week 4, and week 10 after transfusion). The primary endpoint is the cumulative incidence of one or more targeted TTIs from the Mirasol-treated WB vs. standard WB in a previously negative recipient for the specific TTI that is also detected in the donor unit. Log-binomial regression models will be used to estimate the relative risk reduction of a TTI by 10 weeks associated with Mirasol PRT. The clinical effectiveness of Mirasol WB compared to standard WB products in recipients will also be evaluated. Discussion: Screening infrastructure for TTIs in low-resource settings has gaps, even for major TTIs. PRT presents a fast, potentially cost-effective, and easy-to-use technology to improve blood safety. MERIT is the largest clinical trial designed to evaluate the use of Mirasol PRT for WB. In addition, this trial will provide data on TTIs in Uganda. Trial registration: Mirasol Evaluation of Reduction in Infections Trial (MERIT) NCT03737669. Registered on 9 November 2018.
