Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 to 55 years
  • All sexes
  • Healthy volunteers accepted
  • Adult

Who may be able to join

  • Male and female adult participants who are overtly healthy as determined by medical evaluation including medical history, physical examination, and laboratory tests.

Who cannot join

  • Prior self-reported history of any chronic relapsing inflammatory skin disease, including atopic dermatitis.
  • Evidence or history of clinically significant hematological, renal, endocrine, pulmonary, gastrointestinal, cardiovascular, hepatic, psychiatric, neurological, or allergic disease (including drug allergies, but excluding untreated, asymptomatic, seasonal allergies at the time of dosing). Any clinically significant medical conditions or history of such conditions that, in the opinion of the Investigator may place the participant at an unacceptable risk as a participant in this trial.
  • History of human immunodeficiency virus (HIV) infection, hepatitis B, or hepatitis C; positive testing for HIV, hepatitis B surface antigen (HBsAg), hepatitis B core antibody (HBcAb), or hepatitis C antibody (HCVAb). Hepatitis B vaccination is allowed.
  • History of serious adverse reactions or hypersensitivity to any topical drug (eg, crisaborole); or known allergy to any of the test product(s) or any components (eg, lactic acid) in the test product(s) or history of hypersensitivity; or allergic reactions to any of the study preparations
  • Abnormal physical findings of clinical significance or dermatological condition (eg extensive tattooing or excessive scarring at 14 sensitive skin application sites) at the Screening examination or Baseline which would interfere with the objectives of the study in the opinion of the Principal Investigator.
  • Daily use of medications that could interfere with the objectives of the study (such as lidocaine, gabapentin, pregabalin, narcotics, antihistamines, oral or parenteral corticosteroids, non-narcotic analgesics and anti-inflammatories) within 1 week of screening and during the study.
  • Not willing to refrain from shaving, the use of depilatories or other hair-removal activities, antiperspirants, lotions, skin creams, fragrances or perfumes, or body oils (eg, baby oil; coconut oil), use of hair products, hair gels, and hair oil in the treatment areas for 48 hours prior to admission to the PCRU and for the duration of the stay in the PCRU.

About this study

Official title: PHASE 1 RANDOMIZED, DOUBLE-BLIND, VEHICLE-CONTROLLED, INTRA-SUBJECT STUDY TO ASSESS LOCAL TOLERABILITY OF CRISABOROLE 2% OINTMENT AND VEHICLE IN HEALTHY PARTICIPANTS USING SUBJECT-REPORTED ASSESSMENTS AND OBJECTIVE MEASUREMENTS

A double-blind within-subject study to estimate observed application site adverse events following topical applications of crisaborole and vehicle in healthy participants

Read the detailed description

To further understand the potential for crisaborole to evoke skin irritancy, a within-subject comparison study, C3291042 will assess the local tolerability of crisaborole 5 mg/cm² in healthy participants, who have had baseline assessments of surrogate markers of skin sensitivity-i.e. current perception threshold (CPT) measurements and standardized lactic acid stinging test (LAST) assessments. To further the clinical understanding of application site pain, responses to crisaborole ointment compared to crisaborole vehicle ointment will be assessed in comparisons based upon CPT (low versus high; symmetry versus asymmetry) and response to LAST ("stingers" versus "non-stingers"). This exploration of skin sensitivity characterizations in healthy participants exposed to crisaborole 5 mg/cm² will assess application site burning, stinging, and pain as well as other application site characteristics selected from a MedDRA-based list of terms by the participants. More advanced understanding of baseline application site sensation in healthy participants prior to higher local application rate of topical crisaborole may provide strategies for topical dermatologic product development programs striving to prevent or minimize application site sensory adverse events.

What is being measured

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

  1. Frequency and Severity of Application site treatment emergent adverse events (TEAEs) in crisaborole treated versus vehicle-treated prespecified sensitive skin sites

    Comparison of investigator-reported (Application Site Skin Examination [0 to 3 points]) and participant-reported (Local Tolerability Assessment Scale scores [0 to 3 points]) application site TEAEs in crisaborole treated versus vehicle-treated at all 7 prespecified sensitive skin sites.

    Measured: 3 days

Secondary outcomes (2)
  1. Neurometric Measurement (Current Perception Threshold in mAmps) on Right-side and Left-side of Body (face, upper and lower extremities bilaterally)

    Comparison of Current Perception Threshold (CPT) measurements in participants bilaterally (face, upper extremities, lower extremities) to summarize CPT (absolute value in milliAmperes and right-left differential in milliAmperes) prior to study drug dosing (CPT assessments performed at 5 Hz, 250 Hz, and 2000 Hz) .

    Measured: 1 day

  2. Quantify Participant's response to Lactic Acid Stinging Test (LAST) utilizing the Local Tolerability Assessment Scale (ranging from 0 to 3 points) to categorize as Stinger or Non-stinger

    Lactic Acid Stinging Test assessment showing Local Tolerability Assessment Scale score of 2 or 3 on lactic acid treated side AND a difference of at least 1 between lactic acid treated side and placebo treated side (ie, "stingers") versus Local Tolerability Assessment Scale score [ranging from 0 to 3 points] of 1 or less on lactic acid treated side (ie, "non-stingers").

    Measured: 1 day

Model description
Using surrogate markers of skin sensitivity (current perception threshold and lactic acid stinging test responses) to stratify risk for developing application site treatment emergent adverse events (AS-TEAEs), within-subject comparisons will quantify AS-TEAE frequency and severity in healthy participants following double-blind applications of crisaborole ointment and vehicle ointment at 7 sensitive skin anatomic locations.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study of Healthy, run by Pfizer at 1 site in United States.

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 1 inclusion and 7 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 24 Jun 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 United States. 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. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Frequency and Severity of Application site treatment emergent adverse events (TEAEs) in crisaborole treated versus vehicle-treated prespecified sensitive skin sites (time frame: 3 days). 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 24 Jun 2019.
