Trial Outcomes & Findings for Nevirapine vs. Atazanavir Boosted With Ritonavir on a Background of Truvada in Human Immunodeficiency Virus (HIV) Infected Naive Patients (NEwArT) (NCT NCT00552240)

NCT ID: NCT00552240

Last Updated: 2014-01-27

Results Overview

VR is defined as HIV viral load of \<50 copies/ml measured at two consecutive visits PRIOR TO Week 48 and without subsequent rebound or change of ARV therapy prior to Week 48.

Participant Flow

Patients were recruited from 28 Sep 2007 through 23 Mar 2009 at 18 sites throughout the US. The sites were comprised of medical centers or private practice physicians.

There was a 28 day screening period where a genotype report was run. If patients were resistant to any of the study medication, they were not to be randomized into the study. Patients also needed to meet all inclusion/exclusion criteria in order to be eligible. 154 patients were enrolled but 2 were not treated, leaving 152 in full analysis set.
