Study Assessing Dolutegravir in HIV-1 Infected Subjects With Virus Resistant to Raltegravir and/or Elivitegravir — VIKING-4  

HIV Infections Clinical Trial

Official title: A Phase III Randomized, Double-blind Study to Demonstrate the Antiviral Activity of Dolutegravir (DTG) 50 mg Twice Daily Versus Placebo Both Co-Administered With a Failing Antiretroviral Regimen Over Seven Days, Followed by an Open Label Phase With All Subjects Receiving DTG 50 mg Twice Daily Co-administered With an Optimised Background Regimen (OBR) in HIV-1 Infected, Integrase Inhibitor Therapy-Experienced and Resistant, Adults

Status Completed

Clinical Trial Summary

Study ING116529 is a multicenter, randomized, study with an initial 7 day placebo- controlled, functional monotherapy phase to quantify the antiviral activity attributable to dolutegravir (DTG) in HIV-1 infected, ART-experienced adults who are experiencing virological failure on an Integrase inhibitor containing regimen (current RAL or ELV failures), with evidence of genotypic resistance to RAL or ELV at study entry. Thirty subjects will be randomized (1:1) to receive either DTG 50mg BID (Arm A) or Placebo (Arm B) with the current failing regimen for 7 days (RAL or ELV should be discontinued prior to dosing with DTG). At Day 8, subjects from both arms will enter an open label phase and receive open label DTG 50mg BID with an optimized background regimen containing at least one fully active drug.

Clinical Trial Description

Study ING116529 is a multicenter, randomized, study with an initial 7 day placebo-controlled, functional monotherapy phase to assess the antiviral activity and safety of a dolutegravir (DTG, GSK1349572) containing regimen in HIV-1 infected, ART-experienced adults with virological failure on an integrase inhibitor (INI) containing regimen.

Subjects must have evidence of genotypic resistance to raltegravir [RAL] or elvitegravir [ELV] at Screening and documented current or historical genotypic or phenotypic resistance to at least two other antiretroviral therapy drug classes.

The study is designed to provide an accurate measure of the intrinsic antiviral activity of DTG 50mg twice daily versus placebo both administered with the current failing regimen in a randomised double-blind phase to Day 8. This will be followed by an open label phase with all subjects receiving DTG 50mg twice daily with an optimized background regimen (containing at least one fully active drug) until subjects no longer derive clinical benefit or until DTG is locally available. Thirty subjects will be randomized (1:1) to receive either DTG 50mg BID (Arm A) or Placebo (Arm B) with the current failing regimen for 7 days (RAL or ELV should be discontinued prior to dosing at Day 1). At Day 8, subjects from both arms will enter an open label phase and receive open label DTG 50mg BID with an optimized background regimen containing at least one fully active drug The primary analysis will be conducted after the last subject enrolled has completed the randomised, double-blind phase at Day 8. Additional analyses may be performed prior to study closure when all ongoing subjects transition to locally available commercial DTG. ;
