Study to Evaluate the Efficacy and Safety of Oral Difelikefalin (CR845) for Moderate to Severe Pruritus in Subjects With Atopic Dermatitis

2019-07-18 10:31:15 | BioPortfolio


This is a multicenter, randomized, double-blind, 4-arm, placebo-controlled study to evaluate the efficacy and safety of twice-daily (BID) oral difelikefalin (CR845) in adult subjects with atopic dermatitis (AD) and moderate to severe pruritus.


The study will consist of a 30-day Screening period, a 7-day Run-In period, a 12-week Placebo-Controlled Treatment period followed by a 4-week Active Extension period and a Follow Up visit approximately 7 days after the last dose of study drug.

All subjects will sign an informed consent form (ICF) and undergo screening for study eligibility.

Subjects will be randomized in a 1:1:1:1 ratio to receive either placebo or difelikefalin (CR845) tablets at a dose of 0.25 mg, 0.5 mg, or 1.0 mg, orally BID. Intake of the first dose of study drug will be at Day 1.

Subjects who complete the Placebo-Controlled Treatment period of the study will transition into the Active Extension upon completion of the Week 12 visit assessments. All subjects in the Active Extension will receive difelikefalin (CR845).
