| Scientific title | A randomised, triple-arm study to compare the viral and immunological outcome of highly active anti-retroviral therapy during six versus 15 months versus no treatment in patients with primary human immunodeficiency virus-1 (HIV 1) infection |
| Study acronym | Primo-SHM |
| Study objectives | The aim of this study is to provide data on the effect of treatment during primary human immunodeficiency virus infection (PHI) on the viral set-point and the optimal duration of such treatment. |
| Ethics approval(s) | Approval received from the AMC Medical Ethics Committee (ref: MEC 03/059). |
| Health condition(s) or problem(s) studied | Human immunodeficiency virus (HIV), primary human immunodeficiency virus-1 (HIV-1) infection |
| Intervention | Six or 15 months of highly-active anti-retroviral therapy (HAART) initiated during primary HIV-1 infection. As of 11/08/2010 the status of this record is that inclusion to the trial has stopped and follow-up is ongoing. |
| Intervention type | Drug |
| Pharmaceutical study type(s) | |
| Phase | Not Specified |
| Drug / device / biological / vaccine name(s) | Highly active anti-retroviral therapy (HAART) |
| Primary outcome measure | Plasma HIV-1 RNA at week 96: 1. Magnitude of viral set-point will be evaluated for both treatment groups 36 weeks after treatment discontinuation, and a comparison will be made between all groups at week 96 (= study end) 2. Comparison between all three groups of viral kinetics (including rebound) during the off-treatment periods |
| Secondary outcome measures | 1. CD4+ cell counts 2. Safety: (serious) adverse events, HIV related events and death 3. Quality of life 4. Time between diagnosis and start/reinitiation of HAART 5. Time between treatment discontinuation and reinitiation of HAART In selected groups/individuals: 6. HIV-1 specific CD4+ and CD8+ T-cell response and their state of activation and maturation 7. Humoral immune response parameters |
| Overall study start date | 01/05/2003 |
| Completion date | 01/02/2012 |
Eligibility

Enzyme-linked immunosorbent assay (ELISA): HIV-1 specific antibodies negative, or 2. ELISA: low level antibodies or HIV-1 specific antibodies positive and a negative, incomplete or indeterminate Western Blot (antibodies against a maximum of three of the HIV specific proteins), or 3. ELISA: HIV-1 specific antibodies positive and positive Western Blot, but with documented negative HIV-1 ELISA in the preceding 180 days |
| Key exclusion criteria | Does not comply with the above inclusion criteria |
