Inclusion Criteria

• •1. HIV-1 infected males or females at least 18 years of age.
• •2. Three-class (Nucleoside reverse transcriptase inhibitor (NRTI), Non nucleoside reverse transcriptase inhibitor (NNRTI), and Protease inhibitor (PI)) treatment-experienced (a minimum of 3-months duration for each class) with resistance to more than one PI (on the screening resistance testing). Patients that are NNRTI-naïve patients but who have genotypically documented NNRTI-resistance mutations on past or screening resistance testing would be eligible.
• •3. CD4+ T lymphocyte count ≥50 cells/µl and HIV-1 VL ≥1000 copies/mL at screening.
• •4. The ARV study treatment regimen must consist of new TPV/r in combination with an OBR of 2-4 agents of the following: N(t)RTIs (NRTI or NtRTI), enfuvirtide (ENF), and/or, where available, an Expanded Access Program (EAP) investigational agent (Section 3.3). In total, patients are to have an ARV study treatment regimen consisting of at least 3 agents (TPV/r and two OBRs).
• •5. Chronic hepatitis C Virus (HCV) infection demonstrated by HCV-ribonucleic acid (RNA) positivity or, Chronic hepatitis B (HB) infection demonstrated by anti HBc IgG Antibody and HB Surface Antigen positivity.
• •6. Acceptable screening laboratory values that indicate adequate baseline organ function.
• •7. Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) \< Division of AIDS (DAIDS) Grade 3.
• •8. Acceptable medical history, as assessed by the investigator.
• •9. Any AIDS defining illness listed in the Appendix 10.3.1 should be accepted as long as is resolved, asymptomatic or stable on treatment for at least 12 weeks before screening (Visit 1); the AIDS defining events listed below are not acceptable History of Progressive Multifocal Leukoencephalopathy (PML), Visceral Kaposi's Sarcoma (KS), and/or any malignancy.
• •10. A reliable method of barrier contraception will be used by all female patients who are of reproductive potential, for at least three months prior to Visit 3, during the trial, and 30 days after completion or termination from the trial.
• •11. Karnofsky performance score ≥70.
• •9. Use of concomitant drugs that may significantly reduce plasma levels of the study medications.
• •10. Use of immunomodulatory drugs or antineoplastic agents within 30 days before study entry or during the trial.
• •11. Inability to adhere to the requirements of the protocol, including active substance abuse, as defined by the investigator.
• •12. Anticipated need for an interferon-based regimen in the 48 weeks following the study entry.
• •13. Any other or additional plausible cause for chronic liver disease, including the presence of other viruses known or suspected to cause hepatitis.
• •14. Any active infection or neoplasm currently being treated.
• •15. Patients with history of hemorrhagic stroke or intracranial aneurysm.
• •16. Patients with history of ischemic stroke, neurosurgery, skull trauma and/or intracranial pathology (arteriovenous malformation, brain tumors and cerebral venous thrombosis) within 4 weeks prior to screening (Visit 1) as assessed by investigator.
• •17. Patients with current history of alcohol abuse defined as alcohol consumption that would interfere with patient's compliance or result in biological abnormalities.
