A Study of the Efficacy and Safety of Orvepitant in Subjects With Pruritus Associated With Atopic Dermatitis
- Registration Number
- NCT03464526
- Lead Sponsor
- Nerre Therapeutics Ltd.
- Brief Summary
The purpose of this study is to determine the effectiveness of three doses of orvepitant, taken once a day, in the treatment of pruritus associated with atopic dermatitis.
- Detailed Description
A multi-center, double-blind, randomized, parallel group, placebo-controlled dose range study in subjects with pruritus associated with atopic dermatitis.
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 100 subjects, randomized 1:1:1:1 (approximately 400 subjects in total).
All subjects will enter a two-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 four weeks after the end of the treatment period.
