Trial Outcomes & Findings for Observational Study of Nevirapine Extended Release in Human Immunodeficiency Virus (HIV) Patients in Daily Clinical Practice (NCT NCT01524900)

NCT ID: NCT01524900

Last Updated: 2015-06-02

Results Overview

SECONDARY outcome

Timeframe: 24 weeks

Population: Patients from the Full analysis set (FAS): This patient set includes all patients in the treated set who have analysable data in at least one efficacy endpoint.

Virologic response is defined as confirmed Human Immunodeficiency Virus (HIV) viral load of \< 50 copies/mL (at two consecutive measurements after baseline) up to week 24 and without subsequent rebound or change of anti-retroviral (ARV) therapy up to week 24. A rebound is defined as two consecutive measurements of viral load (VL) ≥ 50 copies/mL, at least two weeks apart, after two consecutive measurements of VL\< 50 copies/mL. A change of ARV therapy is defined as a permanent discontinuation of nevirapine extended release, addition of new ARV drugs, or alteration in background therapy. A change in the background therapy due to toxicity or intolerance is not considered as treatment failure. If no follow-up viral load was available the virologic response is Missing.

SECONDARY outcome

Timeframe: baseline and week 24

Population: Patients from FAS with documented CD4+ at baseline and after 24 weeks.

The change in the Cluster of differentiation 4 (CD4+) cell count from baseline after 24 weeks was calculated by subtracting the baseline value from the value after 24 weeks. Therefore, a positive change represents an increase in CD4+ cell count.

SECONDARY outcome

Timeframe: baseline and week 24

Population: Patients from FAS with documented MMAS-8 score at baseline and after 24 weeks.

The Morisky Medication Adherence scale (MMAS-8 scale) is a recognized indicator of medication adherence, consisting of 8 questions with a sum score ranging between 0 and 8 points. The higher score indicates higher adherence to the prescribed therapy recommendation. It has been agreed that the score of 8 could be categorized as having high adherence, score between 6 and 7 as medium adherence and scores of 5 and less as low adherence. The change is presented as the score after 24 weeks minus the score at baseline. Therefore, a positive change score reflects an improvement in the adherence.
