Outcomes

Primary Outcome Measures

Cohort 1: Skin Irritation Index
The skin irritation index is a common measure of skin irritation potential (safety criteria) of investigational product and derived using skin irritation scores. Individual skin irritation score ranges from 0-4, where 0 = no reaction, 0.5 = mild erythema, 1 = erythema, 2 = erythema with edema and papula, 3 = erythema with edema, papula and small water blister, 4 = large water blister, higher score indicates more skin irritation. For each investigational product, the skin irritation index was calculated as the sum of the maximum individual skin irritation scores divided by the number of evaluable participants and multiplied by 100, which ranged from 0 to 400; where, lower score indicated less skin irritation and higher score indicated more skin irritation.
Cohort 2: Number of Participants With Treatment-Emergent Adverse Events (AEs) And Serious Adverse Events (SAEs)
An AE was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. 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 28 days after last dose of study drug (up to Day 36) that were absent before treatment or that worsened relative to pre-treatment state. AEs included both SAEs and non-serious AEs.
Cohort 2: Number of Participants With Clinically Significant Vital Signs Abnormalities
Vital signs included pulse rate and blood pressure. Clinical significance of vital signs was determined at the investigator's discretion.
Cohort 2: Number of Participants With Laboratory Tests Abnormalities
Laboratory tests abnormalities included: hematology (haemoglobin[Hb], haematocrit and erythrocytes<0.8*lower limit of normal[LLN]; erythrocyte mean corpuscular volume, erythrocyte mean corpuscular Hb and erythrocyte mean corpuscular Hb concentration <0.9*LLN and >1.1*upper limit of normal[ULN]; platelets <0.5*LLN and >1.75*ULN; leukocytes <0.6*LLN and >1.5*ULN; lymphocytes/leukocytes[%], neutrophils/leukocytes[%] <0.8*LLN and >1.2*ULN; basophils/leukocytes[%], eosinophils/leukocytes[%], monocytes/leukocytes[% ]>1.2*ULN); clinical chemistry(bilirubin>1.5*ULN; aspartate aminotransferase, alanine aminotransferase and alkaline phosphatase>3.0*ULN; protein and albumin<0.8*LLN and >1.2*ULN; urea nitrogen and creatinine >1.3*ULN; urate>1.2*ULN; sodium <0.95*LLN and >1.05*ULN; potassium, chloride and calcium <0.9*LLN and >1.1*ULN; fasting glucose <0.6*LLN and >1.5*ULN); and urinalysis (pH <4.5 and >8; glucose, ketones, protein, Hb, urobilinogen, bilirubin, nitrite and leukocyte esterase >=1).
Cohort 2: Number of Participants With Clinically Significant Electrocardiogram (ECG) Abnormalities
Criteria for clinically significant ECG abnormalities included: QT interval >=500 milliseconds (msec); QT interval corrected using the Fridericia's formula (QTcF) >=450 msec to <480 msec, >=480 msec and >=500 msec; increase from baseline in QTcF interval >=30 msec to <60 msec and >=60 msec.

Secondary Outcome Measures

Cohort 1: Number of Participants With Treatment-Emergent Adverse Events (AEs) And Serious Adverse Events (SAEs)
An AE was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. 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 28 days after last dose of study drug (up to Day 29) that were absent before treatment or that worsened relative to pre-treatment state. AEs included both SAEs and non-serious AEs.
Cohort 2: Maximum Observed Plasma Concentration (Cmax) of Crisaborole and Its Identified Main Oxidative Metabolites
AN7602 and AN8323 were the main identified oxidative metabolites of Crisaborole.
Cohort 2: Time to Reach Maximum Observed Plasma Concentration (Tmax) of Crisaborole and Its Metabolites
AN7602 and AN8323 were the main identified oxidative metabolites of Crisaborole.
Cohort 2: Area Under the Plasma Concentration-Time Curve From Time Zero Until the Last Measurable Concentration (AUClast) of Crisaborole and Its Identified Main Oxidative Metabolites
AN7602 and AN8323 were the main identified oxidative metabolites of Crisaborole.
Cohort 2: Area Under the Plasma Concentration-Time Curve From Time Zero to the 24 Hours Post-Dose (AUC24) of Crisaborole and Its Identified Main Oxidative Metabolites (AN7602 and AN8323)
AN7602 and AN8323 were the main identified oxidative metabolites of Crisaborole.
Cohort 2: Area Under the Plasma Concentration-Time Curve From Time Zero to Tau (12 Hours Dosing Interval) (AUCtau) of Crisaborole and Its Identified Main Oxidative Metabolites

Cohort 2: Accumulation Ratio for Cmax (Rac [Cmax]) of Crisaborole and Its Identified Main Oxidative Metabolites
AN7602 and AN8323 were the main identified oxidative metabolites of Crisaborole. Accumulation ratio for Cmax (Rac, Cmax) was calculated as Cmax on Day 8 divided by Cmax on Day 1. Cmax was the maximum plasma concentration of Crisaborole and its identified main oxidative metabolites.
Cohort 2: Accumulation Ratio for AUCtau (Rac [AUCtau]) of Crisaborole and Its Identified Main Oxidative Metabolites
AN7602 and AN8323 were the main identified oxidative metabolites of Crisaborole. Accumulation ratio for AUCtau (Rac) was calculated as area under the curve from time zero to end of dosing interval (AUCtau) on Day 8 divided by AUCtau on Day 1. Dosing interval = 12 hours.
