The Dolutegravir Antiretroviral Mono-Therapy for HIV Trial

Status Completed

Clinical Trial Summary

48-week open label randomized phase IV investigator initiated intervention study. The purpose of this study is to evaluate whether HIV-1 suppression can be maintained by DTG monotherapy in HIV-1 infected, virologically suppressed patients on cART.

104 adults fulfilling the in and exclusion criteria and on stable cART will be randomized over 2 investigational arms.

The first arm will contain the direct switch population. This population will switch directly from stable cART to Dolutegravir mono-therapy on baseline visit.

The second arm will contain the delayed-switch population. This group will switch from stable cART to Dolutegravir monotherapy 24 weeks after baseline visit.

The main goal is to investigate if Dolutegravir mono-therapy could be non-inferior to cART in virological suppressed HIV-1 infected adults.

If a interim analysis (performed when 40 patients on dolutegravir monotherapy have passed week 12) shows that it is safe to continue the study, an additional 30 patients will be included on top of the 104 patients needed for the primary endpoint analysis. In contrast to the primary endpoint population, these additional 30 patients will have a CD4 nadir <200 but a CD4 >350 at the time of the screening visit. Besides that, these 30 patients will have to fulfill all other in and exclusion criteria of the primary endpoint population (specifically a viral load never >100.000). These 30 patients are part of a pilot study looking at the possibility to broaden the eligible population in a future larger randomized clinical trial.

Clinical Trial Description

DTG Monotherapy will be considered non-inferior to cART if the lower bound of the one sided 97.5%CI for the difference in proportion of patients reaching the primary endpoint is not lower than -12%. For this purpose, a sample size of 52 per arm would provide 80% power at alpha 0.025 to establish non-inferiority of DTG monotherapy compared with cART when the primary endpoint success rate is 95% in both treatment arms. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
