Detailed Description:
All patients take ABT-378/ritonavir and efavirenz; there are no placebos in this study. Patients take study medications for 48 weeks, during which time there will be 15 study visits. There is a possibility of a study extension after 48 weeks.

Ages Eligible for Study:   Child, Adult, Senior
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria

Patients may be eligible for this study if they:

  • Are HIV-positive.
  • Have a viral load (level of HIV in the blood) of at least 1,000 copies/ml.
  • Have been receiving stable (no changes) anti-HIV treatment that includes at least 1 PI for at least 8 weeks prior to study entry.
  • Have received more than 1 PI for at least 12 weeks each at some time in the past.

Exclusion Criteria

Patients will not be eligible for this study if they:

  • Have had any active opportunistic (AIDS-related) infections within the past 30 days.
  • Have ever received nonnucleoside reverse transcriptase inhibitors (NNRTIs), such as delavirdine, nevirapine, or efavirenz.
