Study of Protease Inhibitor Regimen Switch in HIV-1 Infected Patients With Undetectable Viral Load to Prove the Non-inferiority of Once Daily Dose Regimen Versus the Current Twice Daily Regimen to Maintain the Viral Load Under the Limit of Detection. — RADAR  

HIV Infections Clinical Trial

Official title:
Non-comparative, Opened Study, Evaluating in HIV-1 Infected Patients With Undetectable Viral Load, Treated by an Antiretroviral Combination Including a Protease Inhibitor Boosted With Ritonavir and Administered by Oral Route Twice a Day, the Substitutability of the Current Protease Inhibitor Regimen by the Association Darunavir/Ritonavir 800/100 mg Once a Day to Maintain the Viral Load Under the 50 Copies/ml Limit of Detection After 24 Weeks of Treatment.

Clinical Trial Summary

Darunavir boosted with ritonavir (darunavir/r) is a powerful protease inhibitor, able to reduce the viral load in patients infected with multi-resistant HIV strains; In vitro and in vivo studies have shown that the induction of resistance mutations in the protease gene is much more difficult with the association darunavir/r compared to the other ritonavir-boosted protease inhibitors (PI/r), testifying of a significantly higher genetic barrier to resistance. Moreover, the tolerance to darunavir is good, and the pharmacologic profile of this molecule allows a once daily administration with a 800/100 mg dose in patients infected with a wild HIV strain or with a slightly resistant to darunavir/r strain.

Thus, we propose to evaluate the efficacy of the darunavir/r association once daily as a substitute to a protease inhibitor regimen administered twice daily in patients with undetectable viral load receiving a tritherapy including a protease inhibitor administered twice daily.
