FREE Study: Efficacy and Toxicity of Trizivir - Full Text View

Purpose

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.

Primary Outcome Measures:

Plasma HIV-RNA < 400 cop/ml at week 96 for the Intent- To-Treat (ITT).

Secondary Outcome Measures:

HIV-RNA <50 cop at week 96
HIV-RNA <400 and <50 cop/ml at week 48
Time to virological failure
Immunological efficacy at week 48 and 96 measured by absolute change from baseline in CD4 cell counts
Duration of change in CD4 cell count from baseline to >200,
Proportion of subjects experiencing one or more predefined values of fasting glucose and triglycerides, LDL and LDL/HDL ratio
Development of adverse events

Arms	Assigned Interventions
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)	Drug: zidovudine,lamivudine,abacavir zidovudine 300 mg bid, lamivudine 150mg bid, abacavir 300mg bid
Experimental: Trizivir patients who reach undetectable HIV-RNA within 24 weeks are randomized to switch to trizivir or continuation of combivir/kaletra	Drug: Trizivir

Detailed Description:

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.
