NCT00160329

Brief Summary

The study is looking to compare the impact of lipid levels and HIV viral loads between three different drug regimens: Continuing current regimen (ritonavir boosted regimen), Switching to Atazanavir, or Switching to Atazanavir in combination to Ritonavir.

Outcome Measures

Primary Outcomes (1)

  • Compare the three arms (ATV, ATV/r and continued ritonavir boosted-PI) in the following primary endpoint: % subjects who have normal serum lipid profile off lipid lowering agents and maintain CD4 counts > 75% of baseline line values.

    48 weeks

Secondary Outcomes (7)

  • % subjects with serum lipids within normal limits at week 48 off of any lipid lowering agent.

    48 weeks

  • % subjects who maintain CD4 counts > 75% of baseline values at week 48.

    48 weeks

  • Compare the change in CD4 count and CD4 % at 24 and 48 weeks between the three study arms.1.2.4Compare HIV plasma viral load profile over 24 and 48 weeks as DAVG between the three study arms.

    24 and 48 weeks

  • Compare lipid profile over 48 weeks, change in total cholesterol, TC/HDL ratio and triglycerides.

    48 weeks

  • Compare the evolution of genotypic and phenotypic drug resistance over 12 and 48 weeks between the three arms.

    12 and 48 weeks

  • +2 more secondary outcomes

Interventions

300 mg with ritonavir boosting or 400 mg without

  • Female study volunteers who are not of reproductive potential (who have reached menopause or undergone hysterectomy, bilateral oophorectomy, or tubal ligation) or whose male partner has undergone successful vasectomy with documented azoospermia or has documented azoospermia for any other reason, are eligible without requiring the use of contraception. Acceptable documentation of menopause, sterilization, and azoospermia are as follows:
