This project aims to assess different antiretroviral treatment strategies, optimally controlled and conventional, in relation to drug resistance and virological treatment failure. A Randomised Controlled trial (RCT) where Vietnamese HIV+ patients with CD4+ T-cells <200/ul are randomized into either enhanced treatment support (ETS) through peer supporters or The National AIDS Control Program recommended self supervised treatment (SST). The treatment strategies will be assessed and compared in relation to treatment adherence and drug resistance development with virological treatment failure as primary endpoint. The results from this project will lead to an increased knowledge in relation the impact of treatment support on adherence, virological suppression and resistance development and have an impact on HIV treatment policies in low income settings globally.

Further study details as provided by Karolinska Institutet:

Primary Outcome Measures:
  • Virological treatment failure [ Time Frame: 24 months ]
    HIV viral load of 1 fg reverse transcriptase activity/ml, corresponding to 200 copies/ml, at 1 year and 2 years after starting treatment.

Secondary Outcome Measures:
  • Immunological treatment failure [ Time Frame: 24 months ]

    Immunological treatment failure

    • CD4 count returns to or falls below pre-therapy baseline level or
    • 50% decline from the on-treatment peak value since the initiation of ART (if known); or
    • CD4 count < 100 cells/mm3 after a year without any increase.

  • Clinical treatment failure [ Time Frame: 24 months ]
    Occurrence or recurrence of stage 4 diseases or conditions after at least 6 months of therapy

Enrollment: 640
Study Start Date: August 2007
Estimated Study Completion Date: November 2011
Estimated Primary Completion Date: November 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
No Intervention: Self Supervised Treatment (SST)
Treatment according to the National Treatment Guidelines in Vietnam including treatment counseling before initiation of ART and clinical follow up every 3 months. The patient is self responsible to take the drugs and no additional adherence support is provided.
Experimental: Enhanced Treatment Support (ETS)
Treatment according to the National Treatment Guidelines in Vietnam including treatment counseling before initiation of ART and clinical follow up every 3 months. In addition adherence support is provided according to the description under intervention.
Behavioral: Enhanced Treatment Support (ETS)
An "internal supporter" - family member or other person trusted by the patient is trained to fill in a checklist whether the drugs has been taken and if this was observed. An"external supporter" - a peer selected PLWHA visit the patient twice weekly the first two months. The external supporter follows a checklist and ask about general well being, psychological problems or adverse drugs reactions as well as go through the adherence since last visit, using the internal supporter checklist. If the adherence is good, the number of visits are decreased to once weekly after two months, if not, the number of visits are intensified. If there are any symptoms of opportunistic infections, immunological reconstruction syndrome or adverse drug reactions the patient are refered for medical checkup.
Other Names:
