What is being measured

The primary outcome is the main question the study is designed to answer.

  1. 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.

    Measured: Day 3 to 4

  2. 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.

    Measured: Baseline up to Day 36

  3. 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.

    Measured: Baseline up to end of treatment (Day 8)

  4. 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).

    Measured: Baseline up to end of treatment (Day 8)

  5. 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.

    Measured: Baseline up to end of treatment (Day 8)

Secondary outcomes (8)
  1. 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.

    Measured: Baseline up to Day 29

  2. 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.

    Measured: Pre-dose, 3, 12 and 24 hours post-dose on Day 1 and Day 8

  6. 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

    AN7602 and AN8323 were the main identified oxidative metabolites of Crisaborole. AUC tau was defined as area under the plasma concentration-time curve from time 0 to time tau, the dosing interval, where tau =12 hours.

    Measured: Pre-dose, 3, 12 and 24 hours post-dose on Day 1 and Day 8

  7. 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.

    Measured: Pre-dose, 3, 12 and 24 hours post-dose on Day 1 and 8

  8. 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.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Crisaborole ointment 2% in people with Healthy and Atopic Dermatitis, run by Pfizer at 1 site in Japan.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 8 inclusion and 16 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 1 Mar 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Japan. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 1 Mar 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Cohort 1: Skin Irritation Index (time frame: Day 3 to 4). The study lists 5 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 Mar 2019.
