Description of intervention(s) / exposure
Eligible subjects will be randomized to receive both NEO101 0.95% gel and vehicle-containing placebo gel twice daily for 14 days. Treatment (blinded to treatment assignment) will be administered to the left and right side target skin surface areas for 14 days. A 14-day safety and efficacy assessment period will follow the treatment period.

Outcomes
Primary outcome [1] 3181 0
The primary objective of this study is to evaluate the safety and local tolerability of twice-daily topical application of NEO101 gel for 14 days in subjects with a clinical diagnosis of at least moderate atopic dermatitis.
Timepoint [1] 3181 0
Safety and local tolerability will be assessed during the 14-day treatment period and through the 14-day follow-up period. Physical examinations will be performed at Screening, and on Days 1, 15 and 29.
Secondary outcome [1] 5305 0
1) To make a preliminary evaluation of the efficacy of bid topical application of NEO101 in the reduction or eradication of Staphylococcus aureus.
Timepoint [1] 5305 0
Cultures will be performed on Days 1, 2, 4, 8, 15 and 22
Secondary outcome [2] 5306 0
2) To make a preliminary evaluation of the efficacy of bid topical application of NEO101 in the reduction or eradication of other microorganisms including Streptococci and gram-negative bacteria such as Proteus or Pseudomonas.
Timepoint [2] 5306 0
Cultures will be performed on Days 1, 8 and 15.

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Once a subject is identified as eligible to be randomized into the study, he/she will be assigned a unique subject number, which will correspond to the randomization code indicating which side (left or right) is to be treated with NEO101, while the other side is to be treated with vehicle. The study site will be supplied with blinded numbered study drug kits and a drug dispensation list. Subjects will be randomized to treatment side using the order established on the drug dispensation list. Blinding of treatment assignment is achieved using vials distinguished by a yellow (lemon)-colored label (to be used ONLY for left side application) and a white label (to be used ONLY for right side application).
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Subjects will be assigned a unique subject number, which will correspond to the randomization code indicating which side (left or right) is to be treated with NEO101, while the other side is to be treated with vehicle. The study site will be supplied with blinded numbered study drug kits and a drug dispensation list. Subjects will be randomized to treatment side using the order established on the drug dispensation list. The randomization schedule was developed using a blocked randomization scheme.
