FREE Study: Efficacy and Toxicity of Trizivir
Free Study: a Randomised, Open Label, Multicentre Strategic Study to Evaluate the Efficacy and Toxicity of an Early Switch From a PI-containing Regimen to Trizivir ® on Guidance of Viral Load in HIV-1 Infected , Antiretroviral naïve Adults
Antiretroviral naïve patients with <350 xE6/l CD4 cells and a HIV-viral load of > 30.000 cop/ml are started on combivir ® and Kaletra ®. When patients have reached an undetectable viral load of< 50 cop/ml on two consecutive occasions at least at week 12, but no later than week 24, they are randomised in either continuation with Combivir/Kaletra or switch to Trizivir ® twice daily one pill during 96 weeks. All patients randomised in the combivir/Kaletra arm are eligible to switch to Trizivir at any post randomisation visit when they reach predefined switch criteria for elevated levels of fasting glucose or lipids.
The primary objective is to compare the antiviral efficacy of an early switch from a boosted PI/2NRTI regimen to Trizivir (after undetectability of HIV-RNA has been achieved on 2 consecutive occasions) with uninterrupted use of the PI/2NRTI regimen for 96 weeks.
Phase 3
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
HIV Infections
  • Drug: Trizivir
  • Drug: zidovudine,lamivudine,abacavir
    zidovudine 300 mg bid, lamivudine 150mg bid, abacavir 300mg bid
  • Active Comparator: combivir/kaletra
    All patients started with combivir/Kaletra and were randomized if they reached undetectable viral load (2 times) within 24 weeks into continuation of the same regimen or Trizivir (2 arms)
    Intervention: Drug: zidovudine,lamivudine,abacavir
  • Experimental: Trizivir
    patients who reach undetectable HIV-RNA within 24 weeks are randomized to switch to trizivir or continuation of combivir/kaletra
    Intervention: Drug: Trizivir
