Inclusion Criteria

1. Signed informed consent prior to trial participation.
2. HIV-1 infected male or female > 18 years of age.
3. Three-class (NRTI, NNRTI, and PI) treatment-experienced patients (a minimum of 3 months duration for each class or documented class hypersensitivity/intolerance) with resistance (minimal or reduced response) to more than one PI on the screening virtual phenotype resistance testing. In the case of NNRTIs, NNRTI resistance in the absence of exposure is equivalent to being NNRTI treatment experienced.
4.Patient’s optimized background regimen must contain one of the following ARV options:
• A minimum of two genotypically active nucleoside/nucleotide reverse transcriptase inhibitors (NRTIs) reported as maximal response” or sensitive” on the screening virtual phenotype report.
•A minimum of one genotypically active NRTI reported as maximal response” or sensitive” on the screening virtual phenotype report plus Enfuvirtide if not used previously.
•A minimum of one genotypically active NRTI reported as maximal response” or sensitive” on the screening virtual phenotype report plus an integrase inhibitor if not used previously and if available through an expanded access program and allowed by local regulatory authorities.
•A minimum of one genotypically active NRTI reported as maximal response” or sensitive” on the screening virtual phenotype report plus the CCR5 chemokine receptor antagonist Maraviroc (Pfizer) if available through an expanded access program, not used previously and allowed by local regulatory authorities.
•Zero or one genotypically active NRTI reported as maximal response” or sensitive” on the screening virtual phenotype report plus two of the following drugs, Enfuvirtide, integrase inhibitor and Maraviroc if available, not used previously and allowed by local regulatory authorities.
•Two genotypically partially active NRTIs (provided that they are not part of the current failing regimen) reported as reduced response” on the screening virtual phenotype report plus one of the following drugs, Enfuvirtide, an integrase inhibitor or Maraviroc if available, not used previously and allowed by local regulatory authorities.
For patients who had previously taken 3TC (lamivudine) or FTC (emtricitabine), these drugs are not considered as sensitive regardless of the virtual phenotype report.
5.Patient has been on their current (failing) PI-containing regimen for at least 8 weeks prior to randomization.
6.Patient has on-going viral replication (defined as an HIV-1 viral load
of =500 copies/mL) and a successful virtual phenotype obtained at screening.
7.Any baseline CD4 cell count will be allowed.
8.Karnofsky performance score of = 70 (Appendix 10.7).
9.Acceptable screening laboratory values that indicate adequate baseline organ function.
Laboratory values are considered acceptable if the following apply:
•ALT =2.5 x ULN and AST =2.5 x ULN (?DAIDS Grade 1, Appendix 10.1).
•Any DAIDS grade cholesterol, triglycerides, GGT, CPK or LDH is acceptable.
•All other laboratory test values must be =DAIDS Grade 2.

10.Willingness to initiate CD4+ cell count-guided chemoprophylaxis to prevent opportunistic infections as defined in Appendix 10.3.2.
11.Willingness to abstain from ingesting substances which may alter plasma study drug levels by interaction with the cytochrome P450 system during the study.

Exclusion Criteria

1.Previous use of TPV or DRV.
2.Full genotypic resistance (reported as minimal response”) to TPV or DRV on screening virtual phenotype:
•Minimal response” is defined by the fold change above the Virco upper clinical cutoff values.
3.Female patient of child-bearing potential who:
•has a positive serum pregnancy test at screening
•is breast feeding,
•is planning to become pregnant,
•is not willing to use barrier method protection (listed in Section 3.3.2) or requires ethinyl estradiol administration.

4.History of Progressive Multifocal Leukoencephalopathy (PML), Visceral Kaposi's Sarcoma (KS).
5.Any AIDS defining illness (Appendix 10.3.1) that is unresolved, symptomatic or not stable on treatment for at least 12 weeks at screening visit.
6.Use of immunomodulatory drugs (such as interferon, cyclosporin, hydroxyurea and interleukin 2) within 30 days prior to randomization.
7.Current use of systemic cytotoxic chemotherapy.
8.Inability to adhere to the requirements of the protocol, including active substance abuse as assessed by the investigator.
9.All contraindications listed in the product monographs of Aptivus, Prezista and Norvir.
