Phase 1 Pilot Study of an ART Bridging Regimen in Highly Experienced Patients Unable to Achieve Viral Suppression

Inclusion Criteria:

1. Men and women age > 18 years of age.
2. Ability and willingness to give written informed consent.
3. HIV-1 infection as documented by any licensed ELISA test kit and confirmed by either Western blot, HIV-1 culture, HIV-1 antigen, plasma HIV-1 RNA, or a second antibody test by a method other than ELISA prior to study entry.
4. Patient failed multiple treatment regimens due to development of viral resistance/and or intolerance.
5. Patient's provider feels that patient has exhausted currently available treatment options and that it is highly unlikely that a regimen (including one that contains T-20) could be constructed that would result in sustained virologic suppression at this time.
6. Evidence of MDR virus (broad 3 class resistance) based on the results of the MDR-HIV qualifying screening genotypic resistance test or a history of a previous genotypic resistance test.

7. The following screening laboratory values obtained within 30 days prior to study entry:

   • HIV-1 RNA or BDNA > 10,000 copies/mL

Exclusion Criteria:

1. Active drug or alcohol abuse or dependence which, in the opinion of the investigator, would interfere with adherence to study requirements.
2. History of any illness that, in the opinion of the study investigators, might confound the results of the study or pose additional risk in administering study drugs to the subject.

3. Acute therapy for a serious infection or other serious medical illnesses that are potentially life threatening and require systemic therapy and/or hospitalization.

   NOTE: Subjects with a serious infection or serious medical illness must complete acute therapy at least 7 days prior to study entry. Subjects with all other infections or medical illnesses (e.g., vaginitis, folliculitis, bronchitis, pharyngitis, thrush) must receive appropriate therapy prior to study entry (no time restriction).

4. Significant Renal Insufficiency - calculated creatinine clearance < 50
5. Upon reviewing medication history and genotypic resistance testing, study investigators feel that would be inappropriate to enroll patient in this protocol.
