Bone, Immunologic, and Virologic Effects of a Antiretroviral Regimen

Brief Summary
The main purpose of this study was to compare the effects on bones of the following two drug combinations:
- maraviroc (MVC), emtricitabine (FTC), plus darunavir/ritonavir (DRV/r)
- tenofovir (TDF) plus emtricitabine (FTC) plus darunavir/ritonavir (DRV/r) Additional study objectives were the following:
- To see how the drug combinations affect the brain and kidneys.
- To see how well the drug combinations lower the HIV viral load.
- To see how safe the drug combinations are, how well people are able to take the study drug combinations, and how well their immune systems respond to the study drugs.

Study Arms (2)
MVC Arm: DRV/r + MVC + FTC + TDF placebo
EXPERIMENTALDarunavir 800 mg PO QD + Ritonavir 100 mg PO QD + Maraviroc 150 mg PO QD + Emtricitabine 200 mg PO QD + Placebo for Tenofovir disoproxil fumarate PO QD
TDF Arm: DRV/r + TDF + FTC + MVC placebo
EXPERIMENTALDarunavir 800 mg PO QD + Ritonavir 100 mg PO QD + Emtricitabine 200 mg PO QD + Tenofovir disoproxil fumarate 300 mg PO QD + Placebo for Maraviroc PO QD
Interventions
Darunavir was administered orally once a day as two 400 mg tablets with food. When the 800 mg formulation tablet became available, it was substituted for the two 400 mg tablet.
Ritonavir was administered orally together with darunavir as one 100 mg tablet once daily with food.
Tenofovir disoproxil fumarate was administered orally as one 300 mg tablet once a day.
Emtricitabine was administered orally once a day as one 200 mg capsule.
Placebo for tenofovir disoproxil fumarate was administered orally once a day as one tablet.
Placebo for maraviroc was administered orally once a day as one tablet.
Maraviroc was administered orally once a day as one 150 mg tablet.
Eligibility Criteria
You may qualify if:
- HIV-1 infection
- ARV drug-naïve, defined as \</=10 days of ART at any time prior to study entry, except in the instances defined in section 4.1.3 of the protocol.
- R5-only tropism based on Trofile testing performed within 90 days prior to study entry.
- Screening HIV-1 RNA \>1000 copies/mL obtained within 90 days prior to study entry by any FDA-approved test for quantifying HIV-1 RNA at any laboratory that has a CLIA certification or its equivalent.
- Known hepatitis C virus (HCV) antibody status (performed at any laboratory that had a CLIA certification or its equivalent).
- Certain laboratory values obtained within 60 days prior to study entry, as defined in section 4.1.7 of the protocol.
- For women of reproductive potential, negative serum or urine pregnancy test with a sensitivity of ≤25 mIU/mL within 72 hours prior to study entry.
- Female subjects of reproductive potential, who were participating in sexual activity that could lead to pregnancy, must agree to use at least one reliable method of contraception (as defined in section 4.1.9.1 of the protocol) while receiving the study drugs and for 6 weeks after stopping the medications.
- Female subjects who were not of reproductive potential or whose male partner(s) had azoospermia were eligible to take study drugs without the use of contraceptives.
- Ability and willingness of subject or legal guardian/representative to give written informed consent.
- Willingness to undergo neuropsychological testing.
- DXA scan performed after confirmation of the subject's eligibility by Trofile testing but no more than 4 weeks prior to randomization.
You may not qualify if:
- Use of immunomodulators (e.g., interleukins, interferons, cyclosporine), HIV vaccine, systemic cytotoxic chemotherapy, or investigational therapy within 30 days prior to study entry.
- New use of hormonal therapies within 6 months prior to study entry. (Stable therapy for ≥6 months was permitted.)
- New use of oral contraceptive pills (OCPs) in the past 3 months. (Stable therapy for ≥3 months was permitted.)
- Any oral, intravenous, or inhaled steroids within 30 days prior to study entry. (Intranasal steroids and topical corticosteroids were allowed.)
- Known hypersensitivity to soy lecithin.
- Requirement for any current medications that were prohibited with any study drugs. (Prohibited medications must be discontinued at least 30 days prior to entry. Refer to the A5303 PSWP for a list of prohibited medications.)
- The presence of decompensated cirrhosis.
- A history of or current, active HBV infection defined as positive hepatitis B surface antigen test (or positive HBV DNA in subjects with isolated HBcAb positivity, defined as negative HBsAg, negative HBsAb, and positive HBcAb) at screening.
- Current or prior use of biphosphonates, teriparatide, raloxifene, or denosumab.
- Weight \>300 lbs (exceeds weight limit of DXA scanners).
- History after 18 years of age of fracture of the spine, hip, wrist, or other site thought to be related to osteoporosis or bone fragility.
- Currently breastfeeding.
- Any active psychiatric illness including schizophrenia, severe depression, or severe bipolar affective disorder that, in the opinion of the investigator, could confound the analysis of the neurological examination or neuropsychological test results.
- Active drug or alcohol abuse that, in the investigator's opinion, could prevent compliance with study procedures or confound the analysis of study endpoints.
- Active brain infection (except for HIV-1), fungal meningitis, toxoplasmosis, central nervous system (CNS) lymphoma, brain neoplasm, or space-occupying brain lesion requiring acute or chronic therapy.
