Cohort A: Primary HIV infection:

Documented acute or early infection diagnosed by:

Acute infection:

< 3 bands on Western Blot and any one of: i. positive p24 antigen ii. positive proviral DNA

Early infection:

i. Positive detuned or BED ELISA result OR ii. Previously negative serology within 6 months
of confirmed positive serology.

Cohort B: Chronic HIV infection:

Documented HIV-infection of at least 12 months duration.
Minimum age
18 Years
Maximum age
No limit
Both males and females
Can healthy volunteers participate?
Key exclusion criteria
- Pregnancy or breastfeeding.

- Receipt of investigational products within 1 month of study entry.

- Receipt of any of the following within 6 months of study entry:

- interferon alpha or gamma

- oral corticosteroids (inhaled or topical corticosteroids are permitted)

- cyclosporin

- alkylating agents

- other immunosuppressive agents

- rifampin

Brief summary
The purpose of this study is to measure the decay characteristics of HIV in the blood of
patients after taking a combination of anti-HIV drugs, which includes a new class of anti-HIV
drug, an integrase inhibitor. This study explores how this new combination of therapy reduces
virus in various compartments of the body and immune system.
