Old drug, new trick: can spironolactone silence HIV?
NCT ID NCT07415811
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This small, early study is testing whether spironolactone, a drug already approved for high blood pressure, can reduce the hidden HIV reservoir in people on effective HIV treatment. Researchers will give the drug to 12 adults (both with and without HIV) to see how it affects a key protein and how the body processes it. The goal is to gather initial safety and biological data to see if spironolactone could one day be part of an HIV cure strategy.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Adults aged 18 to 60 years. * Able and willing to provide written informed consent. * For HIV-negative cohort: documented HIV-negative test result at screening. * For HIV-positive cohort: * documented HIV-1 infection; * on stable antiretroviral therapy (ART); .plasma HIV-1 RNA below the limit of detection at screening. Exclusion Criteria: * Pregnancy or breastfeeding. * Known hypersensitivity or contraindication to spironolactone. * Clinically significant baseline electrolyte abnormalities, including hyperkalemia, or conditions that increase the risk of hyperkalemia. * Clinically significant renal dysfunction or hepatic dysfunction that, in the investigator's judgment, increases risk with spironolactone. * History of clinically significant cardiac arrhythmias or screening electrocardiogram findings that contraindicate spironolactone in the investigator's judgment. * Use of aspirin (acetylsalicylic acid) on a continuous basis or recent use prior to screening, or planned use during the study. * Current use of medications or supplements that increase potassium levels or otherwise substantially increase the risk of hyperkalemia, or inability/unwillingness to avoid high-potassium supplements and products during the intervention period. * Use of non-steroidal anti-inflammatory drugs (NSAIDs) or systemic corticosteroids that cannot be discontinued for the duration of study drug administration. * Any condition that, in the investigator's judgment, would interfere with study participation, study procedures, or participant safety.
