Brief 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.


Eligibility criteria: Inclusion Criteria:

* Between 18-70 years of age
* Have been taking TDF and a ritonavir- or cobicistat-boosted protease inhibitor as part of standard care for treatment of HIV

Exclusion Criteria:

* eGFR \< 30 mL/min
* Pregnant or planning pregnancy
* Breastfeeding
* Any medical, social, or mental-health issue(s) that, in the opinion of the investigators, could interfere with study participation or the study outcomes
* Signs or symptoms of decompensated liver disease
* Hepatitis B infection
* Medications that may cause unwanted drug interactions with ledipasvir/sofosbuvir or emtricitabine/tenofovir alafenamide
* Unwillingness or inability to comply with study procedures
* Chronic hepatitis C infection
