A Multicenter, Randomized, Double-Blind, Vehicle-Controlled Study of the Safety and Efficacy of AN2728 Topical Ointment, 2% in Children, Adolescents, and Adults (Ages 2 Years and Older) With Atopic Dermatitis

Number of Participants With Treatment-Emergent Adverse Events (AEs) And Serious Adverse Events (SAEs)

Time Frame: AEs: Baseline (Day 1) up to Day 29, SAEs: Baseline (Day 1) up to Day 36

An AE was any untoward medical occurrence attributed to a participant who received study drug without regard to possibility of causal relationship. An SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; Initial or prolonged inpatient hospitalization; life threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. Treatment-emergent were events between first dose of study drug and up to end of study that were absent before treatment or that worsened relative to pre-treatment state.

Percentage of Participants Who Achieved Treatment Success Based on Investigator's Static Global Assessment (ISGA) at Day 29

Time Frame: Day 29

ISGA assessed the severity of AD (except scalp and venous access area) on a 5-point scale ranged from 0 (clear) to 4 (maximum severe), where higher scores indicate higher degree of AD. Grades for classification of severity: 0= clear (minor residual hypo/hyper pigmentation, no erythema or induration or papulation, no oozing or crusting), 1= almost clear (trace faint pink erythema, with barely perceptible induration or papulation and no oozing or crusting), 2= mild (faint pink erythema with mild induration or papulation and no oozing or crusting), 3= moderate (pink-red erythema with moderate induration or papulation with or without oozing or crusting) and 4= severe (deep or bright red erythema with severe induration or papulation and with oozing or crusting). Treatment success was defined as an ISGA score of Clear (0) or Almost Clear (1) with at least a 2-grade improvement from baseline.

Number of Participants With Clinically Significant Change From Baseline in Vital Signs at Day 29

Time Frame: Baseline, Day 29

Following parameters were analyzed for examination of vital signs: systolic and diastolic blood pressure, respiratory rate and body temperature. Vital sign measurements were performed with the participant in the seated or supine position. Clinical significance of change from baseline value was determined by investigator.

Number of Participants With Clinically Significant Change From Baseline in Laboratory Values at Day 29

Time Frame: Baseline, Day 29

Laboratory values included: Alkaline Phosphatase, Alanine Aminotransferase, Aspartate Aminotransferase, Albumin, Blood Urea Nitrogen, Creatinine, Hematocrit, Hemoglobin, Lymphocytes, Monocytes, Neutrophils, Platelets, Basophils, Eosinophils, Red blood cell count, White blood cell count, Total bilirubin and Glucose (nonfasting), Potassium, Total Protein, and Sodium. Clinical significance of change from baseline value was determined by investigator.
