Brief Summary
Purpose: Perform a 3-phase (single dose, multi dose, dose proportionality) study in healthy volunteers using daily tenofovir+emtricitabine, dolutegravir, and maraviroc dosing to quantify intra- and inter-subject variability and dose proportionality. The influence of covariates on ARV hair distribution (e.g., hair growth rate, race, hair color, hair treatment) will also be measured. Using both population PK modeling and physiologic based PK (PBPK) approaches, a statistical model to quantify ARV adherence patterns based on signal intensity/pattern will be developed. Participants: Healthy volunteers, aged 18 to 70 years of age, inclusive on the date of screening, with an intact gastrointestinal system and at least 1cm caput hair. Procedures (methods): Participants will be sequentially assigned to enroll in a dosing arm, beginning with maraviroc (MVC), then dolutegravir (DTG), and ending with tenofovir/emtricitabine (TFV/FTC). All participants will take a single observed dose of study product in Phase 1, with blood and hair samples obtained on Days 3, 7, 14, 21 and 28 days post-dose. In Phase 2, all participants take 28 days straight of daily dosing, observed, of the same study product. Blood and hair samples obtained on the same days post-dose. In Phase 3, participants will be randomized to stop their drug, or decrease dosing to one or three doses weekly. Hair and blood samples will again be obtained on the same days post-dose. All participants will complete a follow-up safety visit with 14 days of completing study sampling.

Outcome Measures
Primary Outcomes (1)
Hair Antiretroviral Imaging
Signal Strength concentrations will be measured in hair for all study drugs, inclusive of FTC (emtricitabine), tenofovir (TFV), maraviroc (MRV), and dolutegravir (DTG) using Matrix-assisted Laser Desorption Electrospray Ionization (IR-MALDESI) to be reported by signal abundance (au). Signal abundance is the industry standard unit, and higher values represent greater signal with capability to relate to comparative concentrations.
Up to 28 days post dose
Secondary Outcomes (3)
Peripheral Blood Mononuclear Cells (PBMC) Antiretroviral Concentrations
Up to 28 days post-dose
Plasma Antiretroviral Concentrations
Up to 28 days post-dose
Whole Blood Antiretroviral Concentrations
Up to 28 days post-dose
Study Arms (3)
Maraviroc
EXPERIMENTAL12 Healthy subjects will dose with Maraviroc Pill and we will collect blood and hair over all three phases
Dolutegravir
EXPERIMENTAL12 Healthy volunteers will dose with Dolutegravir Pill and we will collect blood and hair over all three phases
Truvada
EXPERIMENTAL12 healthy volunteers will dose with Truvada Pill and we will collect blood and hair over all three phases
Interventions
Subjects will take a single dose in Phase 1, Daily Doses in Phase 2 for 28 days, and then be randomized in Phase 3 to zero doses, one dose a week or three doses weekly

Eligibility Criteria
You may qualify if:
- Healthy volunteer between the ages of 18 and 70, inclusive on the date of screening, with an intact gastrointestinal tract. Healthy is defined as no clinically relevant abnormalities identified by a detailed medical history, full physical examination, including blood pressure and pulse rate measurement, and clinical laboratory tests
- Recent medical history in good medical standing, without evidence of fever five days prior to enrollment
- HIV-negative
- Able to swallow pills
- Has minimum hair required to provide study samples
- Not allergic to any component of the study drug
- Signed and dated informed consent indicating that they have been informed of all pertinent details of the trial and are willing to participate
- Willing and able to comply with scheduled visits, laboratory tests and trial procedures
- Willing to use at least one form of acceptable birth control throughout the duration of the study
- Negative, or receiving treatment, for syphilis at screening
- Hemoglobin Grade 2 or lower, with no clinically significant medical issues that would preclude blood sampling
You may not qualify if:
- Age outside of desired range
- Confirmed positive results for HIV, Hepatitis B or C at screening
- Subjects of all genders actively involved in the conception process, in addition to cisgender female subjects who are in the immediate post-partum period or breastfeeding
- Insufficient amount of hair or unwilling to keep hair length at least 1 centimeter throughout duration of study
- Unable or unwilling to comply with all lifestyle measures and/or visits
- Impaired renal function, as documented by a creatinine clearance \<80 mL/min with the Cockcroft-Gault equation
- Has donated blood within the past 56 days in the amount greater than 500 mL
- Has taken an investigational drug in the past 4 months
- Clinical, laboratory, or surgical abnormalities that would preclude sample collection
- Has a condition, which, in the opinion of the investigator, is likely to interfere with follow-up or ability to take the study medication appropriately
- Any clinically significant laboratory result Grade 2 or greater according to the Division of AIDS (DAIDS) Laboratory Grading Tables
- History of regular alcohol consumption exceeding 14 drinks (1 drink = 5 ounces (150 mL) of wine or 12 ounces (360 mL) of beer or 1.5 ounces (45 mL) of spirits) per week
