  • Hepatic transaminases (AST and ALT) less than or equal to 2x upper limit of normal (ULN)
  • Total bilirubin less than or equal to 1.5 mg/dL
  • Absolute neutrophil count at least 1,500/mm3;
  • Platelets at least 100,000/mm3;
  • Hemoglobin at least 9.5 g/dL
  • Serum amylase less than or equal to 1.5 x ULN
  • Biochemical profile: within normal limits for serum phosphorus, potassium, sodium, and calcium.

排除标准

  • Active untreated syphilis
  • Current uncontrolled hypertension (blood pressure > 160/100 mmHg)
  • Mutually monogamous for > one year with a known HIV antibody negative partner
  • History of chronic renal disease, known osteoporosis, osteomalacia, or osteopenia
  • Current or expected participation in other longitudinal HIV behavioral or biomedical research study
  • Current HIV antiretroviral use
  • Receiving or planning to receive on-going therapy with any nephrotoxic agents or experimental/investigational agents
  • Previous or expected requirements for the administration of immunosuppressive/ immunomodulatory therapy (e.g. chronic systemic steroids, interferon, interleukins, chemotherapy, radiation).
  • Evidence of a gastrointestinal malabsorption syndrome or chronic nausea or vomiting which may confer an inability to receive an orally administered medication.
  • Current alcohol or substance abuse judged by the investigator to potentially interfere with participant compliance.
  • Imminently life-threatening medical conditions (malignancy, immunosuppressive disease [e.g. lymphoma]), or other serious disease or conditions (e.g. cardiovascular, renal, diabetes) within the last 5 years or that are unstable and/or require chronic medication that would impede compliance with study requirements and complicate the interpretation of adverse events
  • Expected to be non-compliant with study visits or planning to move within 24 months to an area where the study will not be conducted
  • Any other clinical or social condition, prior therapy, occupation, or other responsibility, that, in the opinion of the investigator, would interfere with, or serve as a contraindication to study participation or compliance with the dosing requirements.
