Trial Outcomes & Findings for Differentiating the Effects of Substance P and Beta-endorphin (NCT NCT01854177)

NCT ID: NCT01854177

Last Updated: 2018-10-30

Results Overview

Unpleasantness of breathlessness was reported each minute by the patient on a visual analog scale. The scale range is 0-10 where 0 = No breathlessness and 10 = Severe breathlessness. The measures were collected up to 20 minutes per visit and combined for a final score. Total minimum score = 0, total maximum score 200. Data is collected during Resistive Load Breathing at Period 1 (Day 3 or 4) and Period 2 (Day 5, 6 or 7) during which either Placebo or Aprepitant was administered. A high unpleasantness indicates that breathing difficulty feels very bad or terrifying regardless of whether the intensity is high or low

PRIMARY outcome

Timeframe: Visit 2 (Approximately Day 3 where either Placebo or Aprepitant was administered).and Visit 3 (approximately Day 6 where either Placebo or Aprepitant was administered)

Population: One patient was excluded from analysis because there was a 28% difference in her post-bronchodilator FEV1 between visits 2 and 3.

PRIMARY outcome

Timeframe: Visit 2 (Approximately Day 3 where either Placebo or Aprepitant was administered).and Visit 3 (approximately Day 6 where either Placebo or Aprepitant was administered)

Intensity of Breathlessness was recorded on a visual analog scale. The scale range is 0-10 where 0 = minimum and 10 = maximal intensity. At each visit, participants were asked to report unpleasantness at 1 minute intervals. The measures were collected up to 20 minutes per visit and combined for a final score. Total minimum score = 0, total maximum score 200. Data is collected during Resistive Load Breathing at Period 1 (Day 3 or 4) and Period 2 (Day 5, 6 or 7) during which either Placebo or Aprepitant was administered.
