Tolerability Study of the Application of a 3M Microstructure Transdermal System

November 30, 2021 updated by: Murad Alam, Northwestern University

Tolerability Study of the Application of a 3M Microstructure Transdermal System by Finger Pressure to the Face in Healthy Subjects Stratified by Age and Fitzpatrick Skin Type

The purpose of this study is to evaluate the safety and tolerability of an experimental device that introduces microscopic channels into the skin. Creating microscopic channels in the skin allows for better absorption of various medications applied to the skin, and this study will determine if the study device offers a tolerable method by which to introduce these holes. The study population will include 54 individuals, ages 18-74 years old, with a roughly equal distribution of skin colors. Each subject will have a total of three visits 24 hours apart from one another. The study device will be applied at the Baseline and Day 1 visits. At various timepoints before and after device application, skin assessments for irritation will be completed using a 7-point Skin Reaction Scale and photographs will be taken. Subjects will report pain associated with device application using a standardized pain scale. At the baseline visit, a member of the research staff will administer applications of the study device on the side of the subject's forehead, temple and the area below and to the side of the nose on randomly selected sides of the face. The side of the face at each location not receiving application of the study device will receive applications of a "dummy" device. Subjects will not be informed of which device is the study device and which is the "dummy" device. At the Day 1 visit, a member of the research staff will administer study device applications to the center of the subject's forehead. The subject will also self-apply the study device to the chin, under the instruction of the research staff member. At the Day 2 visit, final skin assessments will be made and the subject will be evaluated and treated for any persistent skin irritation. Differences in skin irritation between sites of study device application and "dummy" device application will be determined, as well as several other endpoints.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Actual)

Enrollment

54

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 74 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Age 18-74 years old
  • Subject in good health as determined by the investigator
  • Subject has the willingness and the ability to understand and provide informed consent and communicate with the investigator

Exclusion Criteria:

  • Subjects with active systemic or skin disease (including acne) or skin infection that could, in the opinion of the investigator, interfere with accurate study assessments
  • Baseline skin irritation as defined by a local skin reaction score greater than "0" at any of the application areas (Appendix 1)
  • Facial cosmetic procedures performed within 4 weeks of the baseline visit that may, in the opinion of the investigator, have an impact on skin assessment results†
  • Topical medications applied to the face within 2 weeks of the baseline visit that may, in the opinion of the investigator, have an impact on skin assessment results†
  • Subjects with skin disease such as atopic dermatitis, urticaria or dermatographism that may be exacerbated by device application †Subjects may enroll after a corresponding washout period

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Study device
The study device is a transdermal microneedle array designed to introduce microscopic channels into the skin. The study device arm will receive application of this device.
Device: Transdermal Microchannel Skin System
A member of the research staff will apply the study device to the subject's lateral forehead, temple and nasolabial area on randomly selected sides of the face, 3 times at each anatomical location, for a total of 9 applications. All subjects will also receive 9 adjacent applications to the central forehead, and they will self-administer 3 adjacent applications to the chin under instruction of study staff.
Sham Comparator: Sham device
The sham device will be very similar in appearance to the study device. The sham device arm will receive application of this device.
Device: Sham device
The side not receiving application of the study device at each anatomical location will receive a comparable number of applications of a sham device.
