Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
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.
TDF with a boosted protease inhibitor
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.
Other: Blood draws for tenofovir PK, renal function assessment
TAF with a boosted protease inhibitor
Participants will be switched from tenofovir disoproxil fumarate to tenofovir alafenamide 25 mg/emtricitabine 200 mg with a boosted protease inhibitor.
Other: Blood draws for tenofovir PK, renal function assessment
TAF with a boosted protease inhibitor and LDV/SOF
After taking tenofovir alafenamide/emtricitabine for 12 weeks, participants will then start taking ledipasvir 90 mg/sofosbuvir 400 mg (Harvoni) in combination with the tenofovir alafenamide 25 mg/emtricitabine 200 mg (Descovy) and a boosted protease inhibitor for 4 weeks. Subjects will then return to taking tenofovir alafenamide 25 mg/emtricitabine 200 mg (Descovy) and a boosted protease inhibitor for the final 12 weeks.
Other: Blood draws for tenofovir PK, renal function assessment
