Study Summary

This is a double-blind, randomized, vehicle-controlled study to assess the efficacy, safety, and tolerability of 2 doses of B244 for the treatment of pruritus in adults with a history of atopic dermatitis. Subjects who meet the study entry criteria will be randomized in a 1:1:1 ratio to receive twice daily topical doses of B244 O.D. 5.0, B244 O.D. 20.0, or vehicle (placebo) for 4 weeks.

Primary Outcome

The Itch Numeric Rating Scale (I-NRS) is a validated, self-reported instrument for measurement of itch intensity. It uses a 24-hour recall period and asks subjects to rate the intensity of their itch on an 11-point scale ranging from 0 (no itch) to 10 (worst itch imaginable). Higher scores indicate greater itch intensity. Worst itch intensity (WI-NRS) during a 24-hour recall period will be captured. The question for WI-NRS would be, "Please rate the itching severity due to your atopic dermatitis
