Effects of Ledipasvir/Sofosbuvir Treatment on the Pharmacokinetics and Renal Safety of Tenofovir Alafenamide (TAF) in Patients With HIV.
In Brief
A Phase 4 clinical trial evaluating TDF with a boosted protease inhibitor, TAF with a boosted protease inhibitor, and 1 other intervention for Hepatitis C and HIV Coinfection. Completed, enrolled 10 participants across 1 site.
Detailed Summary
This study will evaluate the effect of ledipasvir/sofosbuvir (LDV/SOF) treatment on the pharmacokinetics (PK) and renal safety of tenofovir in the form of tenofovir alafenamide (TAF). Subjects living with human immunodeficiency virus (HIV) who are receiving tenofovir-based antiretroviral therapy (in the form of tenofovir disoproxil fumarate \[TDF\]), and are also taking a ritonavir- or cobicistat-boosted protease inhibitor will be invited to participate. The study will consist of five visits: a screening visit, three abbreviated 4-hour pharmacokinetic visits, and one end-of-study follow-up visit. Subjects will also be asked to use a Wisepill device, which will track medication adherence throughout the study.

Timeline
Interventions
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
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
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
