Brief Summary:
Human immunodeficiency virus (HIV) persists worldwide as an immense health burden among vulnerable populations. HIV pre-exposure prophylaxis (PrEP) has offered the promise of limiting the global burden of HIV. The objective of this proposal is to conduct a pharmacokinetic (PK) study in transgender women to describe the pharmacokinetics of tenofovir disoproxil fumarate/emtricitabine (TDF/FTC) as PrEP within this population.
Detailed Description:
PrEP is a critical component of comprehensive transgender medical care. The proposed open-label, intensive PK study will inform the pharmacologic impact of combining PrEP and concurrent feminizing hormone regimens. The investigators hypothesize transgender women will achieve similar PrEP concentrations compared to the historical controls, and that hormone concentrations (estrogen and testosterone) will not be affected. The aims of this study are to (1) to determine if concurrent use of TDF/FTC as PrEP in combination with feminizing hormones alters the PK of tenofovir (TFV) and FTC and (2) to determine if concurrent use of PrEP with feminizing hormones alters serum estradiol and testosterone concentrations. To achieve these aims, this study will enroll transgender women who are receiving either oral/sublingual or transdermal estradiol with spironolactone. Using intensive PK sampling, plasma and intracellular TDF/FTC concentrations will be measured after 14 days of oral TDF/FTC.
