ClinConnect Summary

This study allows patients who have successfully participated in ACTG 347 or other trials involving amprenavir to continue treatment with amprenavir, ZDV, d4T, and 3TC. Additionally, this study provides patients whose HIV-1 RNA was not reduced to undetectable levels or who had a significant increase in plasma levels ("treatment failures") the opportunity to change to a potentially more active regimen that includes indinavir, nevirapine, lamivudine, and stavudine.

Patients with HIV RNA less than 500 copies/ml on a regimen containing amprenavir are treated on Arm A; those with greater than o...

  • • Current use of triple therapy with amprenavir/3TC/ZDV (or d4T) for Arm A patients.
  • • Current use of quadruple therapy with IDV/NVP/3TC/d4T for Arm B patients.\]
  • Patients must have:
  • • HIV-positive status.
  • • Successful response to treatment in ACTG 347 as measured by HIV RNA less than 500 copies/ml (Arm A) OR unsuccessful response to treatment in ACTG 347 or another regimen containing amprenavir OR an increase in plasma HIV RNA above the nadir value to greater than 5,000 copies/ml or by at least one log10 at any time (Arm B) OR intolerance to a regimen containing amprenavir.
  • • Consent for patients less than 18 years of age.
  • \[AS PER AMENDMENT 2/27/98:
  • Arm A patients must have:
  • • HIV RNA less than 500 copies/ml on at least one occasion within 60 days of entry while previously enrolled in ACTG 347 and in one of the following categories: currently receiving amprenavir/3TC/ZDV (or d4T) or randomized to monotherapy arm of ACTG 347 and received open-label amprenavir/3TC/ZDV (or d4T).
  • Arm B patients must have:
  • • Failed prior amprenavir therapy, whether on ACTG 347 or not, i.e., HIV RNA greater than or equal to 500 copies/ml after at least 16 weeks of amprenavir and confirmed within 1-6 weeks OR treatment failure that mandated early permanent discontinuation of randomized ACTG 347 study drugs and defined as HIV RNA of at least one log 10 above the nadir (to at least 5,000 copies/ml) or HIV RNA level above the baseline value before 16 weeks of amprenavir and confirmed within 1-6 weeks.
