Inclusion Criteria:

• HIV RNA ≥5000 c/ml

Exclusion Criteria:

• Any antiretroviral therapy within 30 days prior to screening;
• Women of Childbearing potential (WOCBP) unwilling or unable to use an acceptable method to avoid pregnancy for the entire study and for up to 8 weeks after the study;
• WOCBP using a prohibited contraceptive method
• WOCBP who are pregnant or breastfeeding;
• Women with a positive pregnancy test on enrollment or prior to study drug administration;
• Presence of a newly diagnosed HIV-Related opportunistic infection or any medical condition requiring acute therapy at the time of enrollment;
• Suspected primary (acute) HIV infection;
• Prior antiviral therapy (>30 days of NRTI and/or >7 days of non-nucleoside reverse transcriptase inhibitor (NNRTI) or PI therapies) or any antiretroviral therapy within 30 days prior to screening; some exceptions are allowed for ARV therapy in use for Mother-to-child transmission;
• Subjects with Cushing's syndrome;
• Untreated hypothyroidism or hyperthyroidism. A patient who is euthyroid on a stable replacement dose of thyroid hormone is acceptable provided the TSH performed within 30 days of screening is within normal drug range;
• Recent therapy with agents with significant systemic myelosuppressive, neurotoxic, pancreatotoxic, hepatotoxic or cytotoxic potential within 3 months of study start or expected need for such therapy at the time of enrollment; or therapy with methadone or ribavirin/interferons or treatment with neurotoxic drugs or drugs that affect CYP3A4;
• Subjects with obstructive liver disease;
• Active alcohol or substance use sufficient, in the Investigator's opinion, to prevent adequate compliance with study therapy or to increase the risk of developing pancreatitis or chemical hepatitis;
• Proven or suspected acute hepatitis in the 30 days prior to study entry;
• Intractable diarrhea (≥6 loose stools/day for at least 7 consecutive days) within 30 days prior to study entry;
• Inability to swallow capsules;
• Active peripheral neuropathy;
• Presence of cardiomyopathy (due to any cause) or any significant cardiovascular disease, such as unstable ischemic heart disease;
• Known, clinically significant cardiac conduction system disease.

• Baseline laboratory values measured within 2 weeks prior to initiating study drugs as follows:

  1. calculated creatine clearance <60 mL/min as estimated by the Cockcroft-Gault equation;
  2. total serum lipase ≥ 1.4 times the upper limit of normal;
  3. liver enzymes (AST, ALT) ≥ 5 times the upper limit of normal;
  4. total serum bilirubin ≥ 1.5 times the upper limit of normal.
• Hypersensitivity to any component of the formulation of study drug;
• Prohibited therapies;
• Any other clinical conditions or prior therapy that, in the opinion of the Investigator, would make the subject unsuitable for study or unable to comply with the dosing requirements;
• Prisoners or subjects who are compulsorily detained (involuntarily incarcerated) for treatment of either a psychiatric or physical (e.g., infectious disease) illness must not be enrolled into this study.
