Detailed Description
This is a Prospective, Vehicle Controlled, Double-Blind, Multicenter, Randomized Phase II Trial, comparing the effect of twice daily B244 applications for 4 weeks vs vehicle applications on treatment of mild to moderate pruritus associated with atopic dermatitis.
- Approximately 576 subjects may be enrolled.
- The total duration of the study will be approximately 11 weeks. Participants will report for a Screening visit and if all inclusion/exclusion criteria are met, subjects will go through a two-week washout phase before reporting for a Baseline visit.
- After screening and baseline, participants will be randomized to one of two doses of B244 or vehicle application for 4 weeks.
- Randomization will be 1:1:1 so that an equal number of patients will be treated in each Arm of the study.
- All B244 randomized subjects will be treated at the dose of O.D. 5.0 or O.D. 20.0
- Subjects must be willing and able to complete diary within a consistent time frame on a daily basis and to comply with restrictions on allowable therapies for the duration of the study.
- All subjects will attend a screening visit not more than 21 days prior to Baseline (Day 0).
- Subjects will be required to return to the clinic at Baseline, Day 14 (Week 2) and Day 28 (Week 4) visits. All subjects will be asked to attend a Week 8 follow-up visit 4 weeks (28 (±3) days) after the last dose of study medication.
- Subjects will apply a total of 10 pumps of IP per application across all affected areas twice-a-day (i.e. 10 pumps in the morning and 10 pumps again at night) for 4 weeks.
- Safety evaluations will consist of review of participant's medical history at screening and on-going assessment of adverse events reported throughout the study duration.
