• Status: Recruiting
• Trial end date: 2022-12-01
• Target enrollment: 0
• Participant gender: All

Summary

Randomized controlled parallel open-label study in people living with HIV and at least 6 month of treatment with dolutegravir/abacavir/lamivudine prior to inclusion.

Participants (n=95) are randomized to continue 3 drug-regimen dolutegravir/abacavir/lamivudine (control) or switch to two-drug regimen with dolutegravir/lamivudine (intervention). Follow-up is 48 weeks. Data is collected at baseline and week 48. Primary outcome is changes in weight from baseline of more than 2 kg. Secondary outcomes are changes in cardiac risk, composition and calcification of the heart tissue, and changes in body composition and metabolism, inflammation and coagulation. A MRI substudy is applied to focus on the cardiac adverse effects of abacavir.
