Assessment of Drug-drug Interactions Between Masculinizing Hormone Therapy and Antiretroviral Agents Concomitantly for Pre-exposure Prophylaxis Among Transgender Men

Brief summary (registry, in English)

There are currently no published studies addressing drug-drug interactions (DDI) between masculinizing hormone therapy (MHT) and pre-exposure prophylaxis (PrEP) among transgender men (TGM). This could lead to concerns and subsequent prioritizing MHT over PrEP among TGM. Because tenofovir alafenamide (TAF) can achieve higher intracellular tenofovir diphosphate (TFV-DP) levels with lower tenofovir plasma concentrations, it is promising that both plasma tenofovir (TFV) and intracellular TFV-DP levels might not be significantly affected by MHT. The current study aims to determine the pharmacokinetics (PK) DDI between MHT and daily PrEP among TGM.
