Scientific titleShort Pulse AntiRetroviral Therapy At human infection immunodeficiency virus (HIV) seroConversion: a Multicentre randomised trial of therapeutic intervention at primary HIV-1 infection
Study acronymSPARTAC
Study hypothesisThe study is a randomised controlled trial comparing three different strategies of intervention in Primary Human Immunodeficiency Virus (HIV) Infection (PHI). The primary objective is to determine the effect of two anti-HIV treatment schedules of limited duration in PHI on the rate of CD4 decline and, consequently, on the time to initiating long-term anti-HIV therapy. The secondary objective is to evaluate the effect of different durations of treatment during PHI on HIV-specific immune response and disease progression. The aim of early antiretroviral intervention is to preserve HIV-specific CD4+ T-cell responses from HIV-induced lysis in order to confer enhanced control of viral replication when therapy is subsequently discontinued.
Ethics approval(s)The London Multicentre Research Ethics Committee (MREC), 29/07/2004, ref: 04/2/025
ConditionHuman immunodeficiency virus (HIV)
InterventionParticipants will be randomly allocated in a 1:1:1 ratio at trial entry to start one of the regimens of open treatment with:
Arm A: Long course Combination AntiRetroviral Therapy (LCART) for 48 weeks
Arm B: Short course Combination AntiRetroviral Therapy (SCART) for 12 weeks
Arm C: No antiretroviral therapy

The regimen should be started, ideally, on the day of randomisation, or within 72 hours.
Intervention typeDrug
Pharmaceutical study type(s)
PhaseNot Applicable
Drug / device / biological / vaccine name(s)
Primary outcome measureTime to CD4 cell count less than 350 cells/l (excluding counts in the first three months after diagnosis) on two consecutive occasions not more than four weeks apart. Intervention at PHI is termed PTX (primary treatment) to distinguish it from late treatment (LTX), which may be administered according to local HIV treatment guidelines when indicated.
Secondary outcome measures1. HIV-specific CD4+ and CD8+ T-cell responses at week 60
2. Slope of CD4 decline
3. Time from randomisation to virological failure of first regimen of late treatment (LTX) or death
4. Development of drug resistance not present at baseline, before starting LTX or at week 120 whichever is earlier
5. Development of an AutoImmune Deficiency Syndrome (AIDS) defining illness or death
6. Time from randomisation to the initiation of late treatment (LTX)
7. Differences in blood pressure from randomisation at week 12 and week 48
