Clinical Trial: Anti-HIV Treatment Interruptions in HIV Infected Adults in South Africa
This study is not yet open for patient recruitment.
HIV infected people often must take anti-HIV drugs for long periods, leading to long-term drug exposure and toxicity. Interruptions in anti-HIV therapy, also known as structured treatment interruptions (STIs), may have few negative health effects and may be helpful to the overall long-term health of HIV infected people. The purpose of this study is to determine if consecutive STIs are of benefit to HIV infected people who have not previously taken anti-HIV drugs.
|Condition||Treatment or Intervention|
|HIV Infections || Behavior: Structured treatment interruption |
Vaccine: Rabies de novo antigen

Study Type: Interventional
Study Design: Treatment, Randomized, Open Label, Active Control, Parallel Assignment, Safety/Efficacy Study
Expected Total Enrollment: 90
Expected completion: December 2007
Long-term toxicity and the high cost of medications are two problems faced by HIV infected people taking antiretroviral therapy (ART). Previous studies in HIV infected patients suggest that ART with STIs may decrease drug exposure and lessen long-term drug toxicity, while not sacrificing viral suppression and patient health. This study will determine if ART with STIs can maintain the same level of immune function in HIV infected people as continuous ART. This study will recruit patients in South Africa.
This study will last 3.5 years. At study entry, all participants will begin daily ART consisting of lamivudine, lopinavir/ritonavir, and stavudine. At Month 6, only participants who have responded well to ART (CD4 count greater than 250 cells/mm3 and viral load less than 50 copies/ml at Month 6) will be randomly assigned to one of two groups. Group 1 participants will participate in STIs during therapy, and Group 2 participants will receive continuous therapy. People in Group 1 will have treatment interruptions of 2, 4, 8, 8, and 8 weeks of duration in between 12-week periods of ART. People in Group 2 will continue taking ART throughout the study.
At screening, participants will undergo medical history assessment, a physical exam, and magnetic resonance imaging (MRI) and dual energy x-ray absorptiometry (DEXA) scans. There will be at least 27 study visits occurring approximately every 8 weeks, each lasting 45 to 60 minutes. At each study visit, participants will be asked about their quality of life. Blood collection will occur at selected visits. Participants will receive rabies vaccinations at Weeks 40, 41, and 46. A visit at Week 164 will include MRI and DEXA scans, and participants will receive a rabies vaccine booster.
Ages Eligible for Study: 18 Years and above, Genders Eligible for Study: Both
- HIV infected
- CD4 count of 200 to 350 cells/mm3 within 60 days of starting study treatment

- History of AIDS-defining illness (CDC category C). Patients with a history of pulmonary tuberculosis are not excluded.
- Newly diagnosed AIDS-defining opportunistic infection or other condition requiring acute therapy at study entry
- Previous therapy with agents with significant myelosuppressive, neurotoxic, pancreatotoxic, hepatotoxic, or cytotoxic potential within 30 days prior to study entry
- History of immunomodulatory therapy within 4 weeks prior to screening, or cannot abstain from immunomodulators during the study
- Previously received rabies vaccine
- Current alcohol or drug abuse that, in the opinion of the investigator, may interfere with the study
- Diarrhea (more than 6 stools per day for 7 consecutive days) within 30 days prior to study entry
- Active or suspected acute hepatitis within 30 days of study entry
- Bilateral peripheral neuropathy of Grade 2 or higher at screening
- Inability to tolerate oral medication
- Any clinical condition that, in the opinion of the investigator, would interfere with the study
- Pregnancy or breastfeeding
