Study summary

The purpose of this study is to determine the effectiveness of three doses of orvepitant, taken once a day, in the treatment of chronic refractory cough.

Read the detailed description

A multi-center, double-blind, randomized, parallel group, placebo-controlled dose range study in subjects with chronic refractory cough (CRC).

Doses of orvepitant (10 mg/day, 20 mg/day and 30 mg/day) and placebo will be investigated in four parallel groups.

Each group will compromise of approximately 73 subjects, randomized 1:1:1:1 (approximately 292 subjects in total).

All subjects will enter a three-week screening period to determine eligibility. Eligible subjects will be randomized at the Baseline/Day 1 visit and enter a 12-week double-blind dosing period. During this period there will be four visits at Weeks 2, 4, 8 and 12. There will be a final safety follow-up visit at Week 14.

SecondaryChange in the Cough Severity Visual Analogue Scale (VAS) at Week 2 Compared to Baseline - Day-time

The cough VAS is a 100 mm scale on which subjects indicated their severity of cough over the previous 24 hours, both during the day-time and during night time separately. The VAS ranged from "no cough" (0 mm) on the left to "worst cough" (100 mm) on the right. Subjects completed the cough severity VAS at baseline/Day 1 (pre dose) and at Weeks 2, 4, 8, and 12.

In the Global Rating of Change scale, subjects indicated if there had been a change in their symptoms (cough frequency and, separately, cough severity) since starting the IMP. Subjects responded with "worse", "about the same" or "better". If subjects indicated a change (either "worse" or "better") they then indicated on a 7 point scale the degree of change ranging from 1 (almost the same, hardly any change) to 7 (a very great deal changed).

In the Global Rating of Change scale, subjects indicated if there had been a change in their symptoms (cough frequency and, separately, cough severity) since starting the IMP. Subjects responded with "worse", "about the same" or "better". If subjects indicated a change (either "worse" or "better") they then indicated on a 7 point scale the degree of change ranging from 1 (almost the same, hardly any change) to 7 (a very great deal changed). Subjects documented their Global Rating of Change in cough frequency and cough severity at Weeks 2, 4, 8, and 12.
