Clinical Trial Summary

This study will determine whether HIV treatment that is initiated during the acute phase of HIV infection, followed by discontinuation of treatment, is effective in reducing the amount of HIV and an increasing the amount of CD4 cells in the blood of people with HIV, compared to the amounts of HIV and CD4 cells in people who do not receive treatment at this stage.

Description:

Antiretroviral (ARV) therapy for the treatment of HIV infection has been remarkably successful in reducing morbidity and mortality in HIV infected people. This treatment still has its shortcomings, however. Individuals receiving ARV treatment are at risk of toxicity, developing drug resistance, and unknown long-term side effects. Therefore, development of alternative treatment strategies is important. A short course of ARV treatment that is initiated during the acute period of HIV infection, followed by treatment cessation may have a substantial impact on controlling infection and delaying the need for lifelong potent ARV therapy. The purpose of this study is to investigate whether treatment initiated during acute HIV infection and followed by a terminal treatment interruption is effective in lowering the viral load set point and raising CD4 cell counts in people with HIV, as compared to those measures in people with HIV who have received no treatment.

Participants in this study will be randomly assigned to one of three groups. Participants in Group A1 will receive ARV therapy for 12 weeks. Participants in Group A2 will receive ARV therapy for 32 weeks. Participants in Group B will not receive any treatment. This study will not provide medications to any of the groups. All groups will be followed for a total of 72 weeks following study entry. Participants will attend between 30 and 36 study visits over the course of the 72 weeks, depending on their study group. Study visits will occur every week for the first 12 weeks and then every 1 to 6 weeks for the remainder of the study. Tests occurring at study visits may include blood tests, investigational immune system tests, and pregnancy tests. Participants will also undergo a complete physical exam and will be asked to provide information about their medical and medication histories.

Eligibility

Inclusion Criteria:

• Acute HIV infection as determined by a positive HIV viral load (at least 5,000 copies of RNA per ml of plasma) and a negative or indeterminate Western Blot test

• Certain laboratory values. More information about this criterion can be found in the protocol.

• Agrees to use an approved form of contraception

Exclusion Criteria:

• Presence of opportunistic infections or AIDS-defining illnesses, unless they are directly attributable to the acute seroconversion illness

• Receipt of investigational research agents within 30 days prior to study entry

• Receipt of prior experimental HIV vaccines. Individuals who received a saline placebo in a prior HIV vaccine trial are not excluded, provided that they did not receive a sham vector or an adjuvant.

• Receipt of immunosuppressive medications or immunomodulators (e.g., cytokine therapy) within the past 6 months. Participants taking corticosteroid nasal spray for allergic rhinitis; topical corticosteroids for acute, uncomplicated dermatitis; or over the counter medications for acute, uncomplicated dermatitis for a period not longer than 14 days will not be excluded.

• Current use of prohibited concomitant medications

• Current anti-tuberculosis prophylaxis or therapy

• Serious illness other than acute HIV infection requiring systemic treatment or hospitalization until either therapy is completed or patient is clinically stable on therapy

• Hepatitis B surface antigen positivity within 21 days prior to study entry

• Pregnant or breastfeeding

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Difference in the level of HIV RNA at viral load set point if therapy is initiated during acute HIV infection followed by terminal treatment interruption after 12 or 32 weeks of treatment compared to that under no treatment		Week 72
Secondary	Difference in the level of CD4 cells if therapy is initiated during acute HIV infection followed by terminal treatment interruption after 12 or 32 weeks of treatment compared to that under no treatment		Week 72
Secondary	Difference in the level of HIV RNA and CD4 cell numbers between therapy initiated during acute HIV infection followed by terminal treatment interruption after at least 12 weeks of treatment and no therapy at 16 weeks after discontinuation of treatment		Weeks 12 and 16
Secondary	Difference in the level of HIV at viral load set point and CD4 cell number at 72 weeks after study entry if therapy is initiated during acute HIV infection followed by terminal treatment interruption at 12 weeks versus at 32 weeks		Week 72
