- •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).

- •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.
