• Current ART includes either a protease inhibitor or efavirenz
• No documented or suspected resistance to integrase inhibitors or to NRTIs
• No prior history of virologic failure. Failure is defined as a confirmed plasma viral load > 200 cop/ml measured no less than six months after initiation or modification of therapy
• Virological blips accepted only if a single viral load measurement has been between 50-200 cop/ml followed by VL < 50 cop/ml without the need to initiate a change in ART and no blip within 12 month window period prior to screening
• Documented evidence of at least two HIV VL < 50 cop/ml measurements conducted during the past 12 months prior to inclusion: one within 6 months prior to screening
• HIV VL < 50 cop/ml at screening
• BMI>25 kg/m2 and at least one metabolic syndrome condition, which are
o BP ≥ 130/≥ 85 mmHg or hypertension medication currently in use or
o fasting glucose ≥ 5.6 mmol/l or B-HbA1C > 42 mmol/mol or diabetes medication currently in use or
o HDL < 1.0 mmol/l in men and < 1.3 mmol/l in women or triglycerides ≥ 1.7 mmol/l or a cholesterol-lowering regimen currently in use or
o waist circumference > 94 cm in men and >80 cm in women (or respective cut off values for non-European ethnic groups as defined by International Diabetes Federation)
OR
• ultrasound or biopsy proven hepatosteatosis
|
|
E.4 | Principal exclusion criteria |
• Within 12 month window period prior to screening, one or more HIV VL measurement of >50 cop/ml
• More than one consecutive HIV VL measurements of > 50 cop/ml in the treatment history after initial viral suppression with ART
• Chronic hepatitis B or C
• Daily alcohol consumption ≥ 30 g for men and ≥ 20 g for women
• Pregnancy or planned pregnancy during the study period
• Lipid or glucose lowering regimen or hormonal supplement started within 3 months before the planned study start
• Psychiatric disorder, which prevents a study subject to understand the study protocol
• Other serious disease, which prevents a study subject to participate in the study
• For MRI/spectroscopy imaging: metal objects in the body or claustrophobia

E.5 End points |
E.5.1 | Primary end point(s) |
