Primary Outcome Measures:
  • Proportion of patients with viral load < 400 copies/ml at week S24

Secondary Outcome Measures:
  • Clinical and biological safety of the reduced doses of stavudine at week 24. Percentage of patients with viral load < 400 copies/ml at week 48, evolution of Cd4 count from baseline to W24 and 48. Evolution of metabolic parameters from baseline to W24 and

Estimated Enrollment: 57

Estimated Study Completion Date: March 2006
Detailed Description:

Stavudine is a nucleoside inhibitor larged used in HIV treatments and has been associated to mithocondrial toxicity. As it is still largely used in developping countries,the evaluation of reducing dose is of importance.

A single-arm open pilot 48 weeks study to evaluate the capacity of a switch from d4T 40 mg to 30 mg bid in patients with body weight > 60kg to maintain full viral load suppression. Clinical and biological evaluations were carried out at baseline, W24 and W48. Primary end-point is viral load suppression (<400 coies/ml) at W24.

Secondary end-points are : Evolution of CD4 count at W24 and W48, neurological examination at Baseline, W24 and W48, metabolic parameters and stavudine PK at W24.
