Trial Outcomes & Findings for Addition of Raltegravir to Established Antiretroviral Suppressive Therapy (NCT NCT01245101)

NCT ID: NCT01245101

Last Updated: 2016-12-23

Results Overview

These are linear viral cDNAs that are subsequently circularized by the DNA repair apparatus of the host cell to form episomes. They are markers of ongoing viral replication.

Participant Flow

Please note: because of poor enrollment and inability to find the originally planned 40 patients, the study was terminated after only 15 of 20 planned patients had been enrolled into the Raltegravir Then Observation arm. No patients were enrolled into the Observation Then Raltegravir arm.

PRIMARY outcome

Timeframe: 16 weeks

Population: 11 of 12 subjects meeting the per protocol definition were analyzed for the Raltegravir then Observation arm. Poor enrollment led to early termination of study before second arm was activated.

SECONDARY outcome

Timeframe: 16 weeks

Population: 11 of 12 subjects meeting the per protocol definition were analyzed for the Raltegravir then Observation arm. Poor enrollment led to early termination of study before second arm was activated.

Flow cytometry will be performed in whole blood for analysis of markers of immune activation by standard methodology using a LSR-II flow cytometer. Percentage and absolute counts of CD8+CD38+ cells will be determined as the main outcome measure.
