Arms of the Study
Arm 1
Experimental
TAF with a boosted PI and LDV/SOF
Participants who are already taking tenofovir disoproxil fumarate 300 mg (in the form of Viread or Truvada) in combination with either a ritonavir- or cobicistat-boosted protease inhibitor for HIV treatment will continue to take their prescribed treatment for 12 weeks after enrollment. Participants will be switched from tenofovir disoproxil fumarate to tenofovir alafenamide (TAF) 25 mg/emtricitabine (FTC) 200 mg (Descovy) with a boosted protease inhibitor for the next 12 weeks. After taking TAF/FTC for 12 weeks, participants will then start taking ledipasvir 90mg/sofosbuvir 400mg (LDV/SOV, Harvoni) in combination with TAF/FTC and a boosted protease inhibitor for 4 weeks. Participants will then return to taking TAF/FTC with a boosted protease inhibitor for the final 12 weeks of the study.
