|---|---|
|
Experimental: Switch ART

B/FTC/TAF is bictegravir + tenofovir alafenamide + emtricitabine in one pill (single tablet regimen)
|
|
Active Comparator: Continue Current ART
Continue current antiretroviral therapy (ART) therapy (which is emtricitabine plus tenofovir disoproxil fumarate or tenofovir alafenamide plus 3rd agent) for 48 weeks.

Hepatic Fat Content
Time Frame: Baseline
|
The controlled attenuation parameter (CAP) indicates quantity of fat in the liver (that is, hepatic fat content).
CAP is assessed by performing transient elastography (TE) using a FibroScan device, which uses ultrasound.
The CAP score is measured in decibels per meter (dB/m).
CAP score ranges from 100 dB/m to 400 dB/m, and a higher score indicates greater hepatic fat content.

Insulin Resistance
Time Frame: Baseline
|
The Homeostatic Assessment Model of Insulin Resistance (HOMA-IR) is an index used to determine if insulin resistance is present.
HOMA-IR is calculated as ([(fasting insulin in mU/L) x (glucose in mmol/L)]/22.5).
Higher HOMA-IR values indicate greater insulin resistance.
The threshold HOMA-IR value that indicates insulin resistance differs among different populations, but a common clinical cutoff is 2.6 (in other words, a HOMA-IR value of 2.6 or above is commonly interpreted to indicate insulin resistance).

Hepatic Fibrosis as Indicated by Liver Stiffness Measurement
Time Frame: Baseline
|
Fibrosis (that is, scarring of the liver) results in liver stiffness, and liver stiffness can be measured by liver elastography using a FibroScan device, which uses ultrasound.
The liver stiffness measurement ranges from 2 kPa to 75 kPa, with a higher score indicating greater liver scarring and stiffness
