The Department of Defense, through the Defense Health Agency (DHA), is seeking contractor support for a clinical study titled "Malaria Radical Cure Drug Efficacy Clinical Study." This initiative involves two clinical studies over a four-year period, focusing on the efficacy of tafenoquine against Plasmodium vivax in Thailand and its safety and pharmacokinetics in healthy adults in the U.S. The project is structured into three phases: pre-study preparation, clinical study execution and reporting, and data analysis and manuscript preparation, with ongoing malaria research and laboratory support also required. Interested parties must submit their responses to the Request for Information (RFI) by 11:00 AM ET on December 10, 2025, via email to Ashley N. Atkins at ashley.n.atkins.civ@health.mil.
