Trial Outcomes & Findings for Ledipasvir/Sofosbuvir Fixed-Dose Combination on Cerebral Metabolism and Neurocognition in Treatment-Naive and Treatment-Experienced Participants With Chronic Genotype 1 HCV Infection (NCT NCT02219685)

NCT ID: NCT02219685

Last Updated: 2018-11-16

Results Overview

MRS was analyzed in the LCmodel program and measured in 3 specific areas of brain (basal ganglia, frontal cortex, and dorsolateral prefrontal cortex). The cerebral metabolic signal N-acetylaspartate (NAA) + N-acetylaspartylglutamate (NAAG) was analyzed. Spectroscopy results are expressed as metabolic ratio with creatine used as the control metabolite, so there are no units of measure.

The SF-36 Health Survey is a self-reporting, multi-item scale measuring 8 health concepts: 1) physical functioning, 2) role limitations due to physical health problems, 3) bodily pain, 4) general health, 5) vitality (energy/fatigue), 6) social functioning, 7) role limitations due to emotional problems and 8) mental health (psychological distress and psychological well-being). The first 6 concepts constitute the physical component summary. The total score is an average of the individual question scores, which are scaled 0-100 with lower scores representing more disability and higher scores representing less disability.

The CLDQ-HCV is a disease-specific questionnaire measuring health-related quality of life. CLDQ-HCV scores are calculated using participant responses to 29 questions divided into 4 domains: Activity/Energy, Emotion, Worry, and Systemic. An overall CLDQ-HCV score is calculated by taking the mean of all domain scores. Overall CLDQ-HCV scores range between 1 and 7, with higher scores representing better quality of life.

Timeframe: Baseline; Posttreatment Weeks 4 and 24

Population: Participants in the Full Analysis Set with available data were analyzed.

The FACIT-Fatigue score was measured using a 40-item questionnaire that assesses self-reported fatigue and its impact upon daily activities and function. Participants scored each item on a 5-point scale from 0 (Not at all) to 4 (Very much). The FACIT-F total score was calculated by taking the sum of all 40 individual scores and ranged from 0-160, with higher scores indicating better quality of life.

Impairment in overall work productivity was measured using the WPAI: Hepatitis C questionnaire completed by participants during study visits throughout the study. This questionnaire measured the effect of hepatitis C on the ability to work and perform regular activities. Overall work impairment is expressed as a percentage and ranges from 0% (no effect) to 100% (completely prevented from working).

The BHS is a 20-item scale for measuring the extent of negative attitudes about the future (pessimism) as perceived by adolescents and adults. The BHS consists of 20 true-false statements. Each of the 20 statements is scored 1 or 0. Of the 20 true-false statements, 9 are keyed FALSE, and 11 are keyed TRUE to indicate endorsement of pessimism about the future. The item scores are summed to yield a total score that can range from 0 to 20 with higher scores indicating greater hopelessness.
