A Phase 3, Randomized, Double-Blind, Switch Study to Evaluate F/TAF in HIV-1 Positive Subjects Who Are Virologically Suppressed on Regimens Containing FTC/TDF

This study will evaluate the efficacy of switching from emtricitabine/tenofovir disoproxil
fumarate (FTC/TDF) fixed dose combination (FDC) to emtricitabine/tenofovir alafenamide
(F/TAF) FDC in HIV-1 positive participants who are virologically suppressed on regimens
containing FTC/TDF.

This study will consist of a 96 week double-blind treatment period. After Week 96, all
participants will continue on blinded study drug treatment and attend visits every 12 weeks
until treatment assignments are unblinded. All participants will return for an unblinding
visit and will be given the option to receive open-label F/TAF and attend visits every 12
weeks until F/TAF is commercially available, or the sponsor terminates the F/TAF clinical
development program.


Key Inclusion Criteria:

- Ability to understand and sign a written informed consent form, which must be obtained
prior to initiation of study procedures

- Currently receiving antiretroviral regimen containing FTC/TDF in combination with one
third agent for ≥ 6 consecutive months prior to screening.

- Plasma HIV-1 RNA levels < 50 copies/mL for at least 6 months preceding the screening
visit (measured at least twice using the same assay) and not experienced two
consecutive HIV-1 RNA above detectable levels after achieving a confirmed (two
consecutive) HIV-1 RNA below detectable levels on the current regimen in the past
year.

- Plasma HIV-1 RNA should be < 50 copies/mL at the screening visit.

- Normal electrocardiogram (ECG)

- Estimated glomerular filtration rate (eGFR) ≥ 50 mL/min according to the
Cockcroft-Gault formula for creatinine clearance

- Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ≤ 5 × the upper
limit of the normal range (ULN)

- Total bilirubin ≤ 1.5 mg/dL, or normal direct bilirubin (individuals with documented
Gilbert's syndrome or with Atazanavir-associated hyperbilirubinemia may have total
bilirubin up to 5 x ULN)

- Adequate hematologic function

- Serum amylase ≤ 5 × ULN

- Females of childbearing potential must agree to utilize highly effective contraception
methods or be non-heterosexually active, or practice abstinence from screening
throughout the duration of the study treatment and for 30 days following the last dose
of the study drug.

- Females who have stopped menstruating for ≥ 12 months but do not have documentation of
ovarian hormonal failure must have a serum follicle stimulating hormone (FSH) level at
screening within the post-menopausal range based on the Central Laboratory reference
range.

- Females who utilize hormonal contraceptive as one of their birth control methods must
have used the same method for at least three months prior to study dosing.

- Males must agree to utilize a highly effective method of contraception during
heterosexual intercourse or be non-heterosexually active, or practice sexual
abstinence from first dose throughout the study period and for 30 days following the
last study drug dose.

Key Exclusion Criteria:

- A new AIDS-defining condition diagnosed within the 30 days prior to screening

- Hepatitis C virus (HCV) antibody positive and HCV RNA detectable

- Individuals experiencing decompensated cirrhosis (e.g., ascites, encephalopathy, etc.)

- Individuals receiving ongoing treatment with bisphosphonate to treat bone disease (eg,
osteoporosis)

- Females who are breastfeeding

- Positive serum pregnancy test

- Have an implanted defibrillator or pacemaker

- Current alcohol or substance use judged by the investigator to potentially interfere
with study compliance

- A history of malignancy within the past 5 years (prior to screening) or ongoing
malignancy other than cutaneous Kaposi's sarcoma (KS), basal cell carcinoma, or
resected, non-invasive cutaneous squamous carcinoma.

- Active, serious infections (other than HIV-1 infection) requiring parenteral
antibiotic or antifungal therapy within 30 days prior to Day 1 Visit

- Individuals receiving ongoing therapy with any of the medications not to be used with
FTC, TAF, TDF or other antiretroviral third agents.

Note: Other protocol defined Inclusion/Exclusion criteria may apply.
