Safety and Durability ofTenofovir and a Cell Cycle Agent for Viral Suppression — HADIT  

HIV Infections Clinical Trial

Official title: A Study to Probe The Safety And Durability of Tenofovir And a Cell Cycle Agent to Maintain Viral Suppression

Status Completed

Clinical Trial Summary

Study Hypothesis Evaluation of the durability of the combination Tenofovir and Hydroxyurea to maintain viral suppression below 50 copies/ml in volunteers who have achieved viral suppression on a standard HAART regimen.

Clinical Trial Description

This is a 48 week open-label, randomized study comparing the safety and durability of a highly active de-intensified therapy (Tenofovir/Hydroxyurea) to a simplified standard of care therapy (Tenofovir plus 3TC or Emtriva plus Sustiva or Nevirapine) to maintain a durable viral suppression.

Up to 20 subjects with chronic HIV-1 infection, suppressed on highly active antiretroviral therapy, and without evidence of viral resistance will be enrolled in this study. Their present HAART therapy will be stopped.

Half of the 20 volunteers will be randomized to the Tenofovir 300 mg qd/Hydroxyurea 500mg qd arm and those subjects will have Hydroxyurea added to their current screening regimen for 4 weeks prior to de-intensifying to Hydroxyurea and Tenofovir. The other half will be randomized to Sustiva 600 mg qd or Nevirapine 200 mg twice a day); Tenofovir 300 mg qd, 3TC 300 mg qd or Emtriva 200 mg once a day. Volunteers will continue on this regimen for 48 weeks. Patients will be monitored for immunological and virological parameters as well as the incidence of toxicity and side effects during the study. If a patient's viral load reaches >400 copies/ml on 3 consecutive measurements over a 6 week period, they will be terminated from the study and started back on their HAART. ;
