简要总结
This study is a phase 3, randomized, double blind and vehicle study to evaluate the efficacy and safety of Crisaborole ointment, 2% in Chinese and Japanese subjects with mild to moderate atopic dermatitis involving at least 5% treatable BSA. Eligible subjects will be randomized in a 2:1 ratio to one of 2 treatment groups (Crisaborole BID, Vehicle BID, respectively).

入选标准
- •Is male or female 2 years and older at the Screening visit/time of informed consent/assent diagnosed with mild-moderate AD (according to the criteria of Hanifin and Rajka), of at least 5% BSA.
排除标准
- •Has any clinically significant medical disorder, condition, or disease (including active or potentially recurrent non AD dermatological conditions and known genetic dermatological conditions that overlap with AD, such as Netherton syndrome) or clinically significant physical examination finding at Screening that in the PI's or designee's opinion may interfere with study objectives.
- •Has participated in a previous crisaborole clinical study.

结局指标
主要结局
Percentage of Participants With Treatment-Emergent Adverse Events (AEs) or Serious Adverse Events (SAEs)
时间窗: Baseline up to Day 60
An adverse event was considered as a treatment-emergent adverse event (TEAE) if the event started after the first dose of treatment regardless of whether a similar event of equal or greater severity existed in the baseline period. 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. AEs are classified according to the severity in 3 categories a) mild - AEs does not interfere with participant's usual function b) moderate - AEs interferes to some extent with participant's usual function c) severe - AEs interferes significantly with participant's usual function.
Percentage of Participants With Clinically Significant Changes From Baseline in Vital Signs
时间窗: Baseline up to Day 29
Vital signs (temperature, respiratory rate, pulse, systolic and diastolic blood pressure) were obtained with participants in the seated position, after having sat/lied calmly for at least 5 minutes. Clinically significant vital signs criteria included Diastolic Blood Pressure (DBP) Value \<50 mmHg, DBP Change ≥20 mmHg increase, DBP Change ≥20 mmHg decrease, Pulse Rate Value \>120 beats per minute (bpm), Systolic Blood Pressure (SBP) Value \<90 mmHg, SBP Change ≥30 mmHg increase, SBP Change ≥30mmHg decrease
Percent Change From Baseline in Eczema Area and Severity Index (EASI) Total Score at Day 29
时间窗: Baseline, Day 29
The EASI quantifies the severity of a participant's AD based on both severity of lesion clinical signs and the percent of body surface area (BSA) affected. EASI is a composite scoring of the degree of erythema, induration/papulation, excoriation, and lichenification (each scored separately) for each of four body regions, with adjustment for the percent of BSA involved for each body region and for the proportion of the body region to the whole body. Total EASI score ranged from 0.0 to 72.0, higher scores = greater severity of AD.
Percentage of Participants With Clinically Significant Changes From Baseline in Clinical Laboratory Parameters
时间窗: Baseline up to Day 29
Laboratory parameters included: hematology and chemistry. Clinically significant laboratory abnormalities are defined as abnormal values that have clinical manifestations or require medical intervention. Clinically significant laboratory criteria included Hemoglobin \<0.8 x lower limit of normal (LLN), Leukocytes \>1.5 x upper limit of normal (ULN), Lymphocytes \<0.8 x LLN, Lymphocytes/Leukocytes \>1.2 x ULN, Neutrophils \<0.8 x LLN, Neutrophils \>1.2x ULN, Neutrophils/Leukocytes \<0.8 x LLN, Basophils/Leukocytes \>1.2 x ULN, Eosinophils \>1.2 x ULN, Eosinophils/Leukocytes \>1.2 x ULN, Monocytes \>1.2 x ULN, Monocytes/Leukocytes (%) \>1.2 x ULN, Bicarbonate \<0.9 x LLN, and Glucose \>1.5x ULN.
