Trial Outcomes & Findings for Modulation of Monocyte Activation by Atorvastatin in HIV Infection (NCT NCT01263938)

NCT ID: NCT01263938

Last Updated: 2019-05-01

Results Overview

Effects of Atorvastatin on immune activation associated surface markers (CD16, CD163 and CCR2) of monocytes were assessed in chronic HIV+/HAART+ subjects following 12 weeks of treatment. Whole blood drawn from these subjects were stained with fluorochrome tagged antibodies to the surface markers. Stained whole blood cells were then acquired on a flow cytometer and analyzed using the Flowjo software to determine the percentage of cells (monocytes) expressing the specific marker. This was done before starting and after completing drug treatment to assess the effect of drug.

Participant Flow

Subjects were recruited from the AIDS Clinical Trial Unit (ACTU) at the Hospital of University Of Pennsylvania, Philadelphia, PA. The screening and recruitment process was carried out during the period September 2011 thru April 2012.

Enrolled participants were assigned to treatment groups based on the nature of HAART therapy (PI- or non-PI based).

PRIMARY outcome

Timeframe: Subjects enrolled in the study following the screening visit were assessed for the primary outcome measures at T=0 (drug intervention begins); T=12wks (intervention ends)

Population: 1\) Percentage of peripheral blood monocyte surface markers: CD16, CD163, CCR2

Effects of Atorvastatin on immune activation associated surface markers (CD16, CD163 and CCR2) of monocytes were assessed in chronic HIV+/HAART+ subjects following 12 weeks of treatment. Whole blood drawn from these subjects were stained with fluorochrome tagged antibodies to the surface markers.
