简要总结
This research application will explore the impact of the Non-nucleoside reverse transcriptase inhibitor (NNRTI) doravirine in the setting of established Nucleoside reverse transcriptase inhibitors (NRTIs) backbone [Tenofovir alafenamide (TAF) / Emtricitabine (FTC) as a possible therapeutic strategy to minimize the detrimental impact of ART-related toxicities on metabolism and instigators of atherosclerosis. Given the possible favorable role of NNRTI in pathogenesis of HIV-related dyslipidemia and cardiovascular disease (CVD), this research will provide mechanistic insights into HIV pathogenesis and safety data regarding doravirine (DOR). These data may promote DOR as a robust "HDL friendly" and "metabolism friendly", therapeutic agent that may attenuate morbidity in chronic treated HIV infection. Towards this aim, the investigators will study DOR-related effects on HDL (HDL-C levels and function) and ex vivo assays that determine key molecular determinants of atherogenesis.
详细描述
Aim 1: To evaluate the relative in vivo impact of DOR on independent measures of HDL function (antioxidant function, cholesterol efflux) compared to integrase inhibitors (raltegravir, dolutegravir, elvitegravir, bictegravir) in the setting of TAF backbone in HIV infected persons with dyslipidemia. Aim 2: To evaluate the relative in vivo impact of DOR on ex vivo atherogenesis (monocyte-derived foam cell efflux and chemotaxis) compared to integrase inhibitors (raltegravir, dolutegravir, elvitegravir, bictegravir) in the setting of TAF backbone.

入排标准
入选标准
- •18 years of age or older
- •Cases: Chronically infected and on anti-retroviral therapy with suppressed viremia for at least 3 months (viral RNA \<50 copies per ml)
- •On stable antiretroviral therapy for \>6 months with Genvoya (elvitegravir 150 mg/cobicistat 150 mg/emtricitabine 200 mg/tenofovir alafenamide 10 mg; E/C/F/TAF) 2) Biktarvy (bictegravir 50 mg/ emtricitabine 200 mg/tenofovir alafenamide 25 mg; B/F/TAF).
- •Dyslipidemia (Defined based on use of lipid lowering medications or abnormal baseline lipids (total cholesterol, triglycerides, high density lipoprotein): Rationale: Enrolling participants with dyslipidemia will determine whether switching from TAF/FTC/integrase inhibitor regimen to TAF/FTC/doravirine regimen will directly improve the lipids over 3 months within the same participant.
- •Adequate renal function determined by the Cockcroft-Gault formula for creatinine clearance (\>60 mL/min/1.73 m2
- •Able and willing to provide written consent
排除标准
- •• Pregnancy
- •Hepatitis; no evidence of acute hepatitis in the prior 30 days
- •History of severe renal impairment (eGFR \< 30 ml/min/1.73 m2)
- •History of severe or recent cardiac event
- •Current alcoholism or IV drug abuse
- •Use of systemic immunomodulatory medications (e.g. steroids) within 4 weeks of enrollment
- •Anemia precluding safe donation of blood (For men, anemia is typically defined as hemoglobin level of less than 13.5 gram/100 ml and in women as hemoglobin of less than 12.0 gram/100 ml).
- •Use of any investigational products within 4 weeks of enrollment
- •Any other clinical condition or prior therapy that, in the opinion of the investigator, would make the patient unsuitable for the study or unable to comply with the study requirements. Such conditions may include, but are not limited to, current or recent history of severe, progressive, or uncontrolled renal, hepatic, hematological, gastrointestinal, endocrine, pulmonary, neurological, or cerebral disease.
- •Subjects who are on medications that are strong inducers of CYP3A (as these may decrease the efficacy of Stribild or Genvoya). Examples include phenobarbital, phenytoin, carbamazepine, and rifampin.
研究组 & 干预措施

PIFELTRO (doravirine) 100 mg tablet one daily for 3 months Descovy (200 mg emtricitabine + 10 mg tenofovir alafenamide fumarate) tablet one daily for 3 months

结局指标
主要结局
HDL function
时间窗: 12 weeks post switch of antivirals
Primary outcome (instigator of atherosclerosis). This is a measure of the lipid peroxide content of HDL per specific amount of HDL relative to the measure of this value in a pooled healthy control (normalized ratio; no units).
Monocyte chemotaxis
时间窗: 12 weeks post switch of antivirals
Primary outcome (instigator of atherosclerosis). This is a measure of the ability of isolated blood monocytes to migrate through a trans endothelial layer in an ex vivo model of atherogenesis. Units are % of monocytes that migrated (% chemotaxis).
Monocyte derived foam cell formation of monocytes
时间窗: 12 weeks post switch of antivirals
Primary outcome (instigator of atherosclerosis). This is a measure of the ability of isolated blood monocytes to take up lipids and form foam cells in an ex vivo model of atherogenesis. Units are % of monocytes that became foam cells (% Monocyte derived foam cell formation).
次要结局
- Total cholesterol(12 weeks post switch of antivirals)
