NCT03207763

Brief Summary

Microneedles can be prepared as a low-cost patch that is simple for patients to apply for vaccine delivery targeting the many antigen-presenting cells present in the skin. Data regarding the safety, reactogenicity, tolerability, and acceptability of a microneedle patch in children are lacking. The goal of this study is to evaluate the safety, reactogenicity, and acceptability of placement of a placebo microneedle patch to the skin of children.

Outcome Measures

Primary Outcomes (3)

  • Number of Participants With Placebo Microneedle Patch-related Serious Adverse Events (SAE).

    To evaluate safety following application of the patch topically, microneedle patch-related serious adverse events were recorded. Information collected included event description, date of onset, severity and date of resolution/stabilization of the event. Severity and relationship to study product was assessed by the Investigator or sub-investigator.

    Day 1 through the Final Study Visit (Day 27 - 38)

  • Number of Participants With Grade 3 Placebo Microneedle Patch-related Solicited Adverse Events (AE).

    The occurrence of Grade 3 solicited adverse events related to the placebo microneedle patch was recorded. Solicited adverse events were irritability (fussiness), lethargy (drowsiness), decreased appetite, vomiting, and fever. The severity of these adverse events was graded on a scale from 0 to 3 where 0 = not present and 3 = significant, preventing daily activity or a fever of \>102.1 degrees Fahrenheit (F).

    Up to Day 8 for Patch 1, Day 8 to Day 15 if received Patches 2 and 3

  • Number of Participants With Solicited Application Site Reactogenicity Events.

    The occurrence of solicited reactogenicity events at the application site was recorded. The solicited reactogenicity events are reactions that are common or expected to occur with application of a microneedle patch and include induration/swelling, erythema, ecchymosis, itching, pain, and tenderness. The Legally Authorized Representatives (LARs) of participants were provided with a memory aid, thermometer and ruler to record the presence of solicited symptoms and oral temperature. Reactogenicity event details were collected via review of the subject's memory aid and by interview with the subject LAR. Reactogenicity events were graded on a scale from 0 (not present) to 3 (significant or severe).

    Up to Day 8 for Patch 1, Day 8 to Day 15 if received Patches 2 and 3

Secondary Outcomes (4)

  • Number of Participants With Grade 3 Placebo Microneedle Patch-related Unsolicited Adverse Events

    Day 1 through the Final Study Visit (Day 27 - 38)

  • Number of New-onset Medical Conditions (NOMC)

    Day 1 through the Final Study Visit (Day 27 - 38).

  • Acceptability of Vaccination Methods

    Final Visit (Day 27 - 38)

  • Overall Experience

    Day 1, Day 2, Day 8, Final Visit (Day 27-38)

Study Arms (2)

Cohort 1

EXPERIMENTAL

Participating infants and children will receive Microneedle Formulation 1. At least 4 infants or children must complete Day 8 without halting criteria having been met before subjects will be enrolled into the next younger age group within a Cohort. At least the first 2 children will have a microneedle patch initially applied to the skin overlying the shoulder blade. If this site is well tolerated without halting criteria having been met additional microneedle patches may be applied to the same participants and in subsequent participants to the upper arm, forearm, wrist and/or thigh.

Device: Microneedle Formulation 1

Cohort 2

EXPERIMENTAL

Participating infants and children will receive Microneedle Formulation 2. At least 4 infants or children must complete Day 8 without halting criteria having been met before subjects will be enrolled into the next younger age group within a Cohort. At least the first 2 children will have a microneedle patch initially applied to the skin overlying the shoulder blade. If this site is well tolerated without halting criteria having been met additional microneedle patches may be applied to the same participants and in subsequent participants to the upper arm, forearm, wrist and/or thigh.

Device: Microneedle Formulation 2

Interventions

Microneedle patches will be made of solid conical structures made of water-soluble excipients that from the Food and Drug Administration's Generally Recognized as Safe (GRAS) list and/or on the FDA list of inactive ingredients in approved products. The total mass of excipients delivered by placebo microneedle patch will be \<1.5 mg. The adhesive backing component is made from hypoallergenic material (commercial medical tapes designed to adhere to skin). Microneedle patches will be administered topically by manual application to the skin. The sites of microneedle patch application will be cleaned with an alcohol swab and allowed to dry before the microneedle patch is applied. The microneedle patches will be packaged and provided as single patches.

Cohort 1

Microneedle patches will be made of solid conical structures made of water-soluble excipients that from the Food and Drug Administration's Generally Recognized as Safe (GRAS) list and/or on the FDA list of inactive ingredients in approved products. The ratio of the excipients and excipients used will vary slightly from Formulation 1. The total mass of excipients delivered by placebo microneedle patch will be \<1.5 mg. The adhesive backing component is made from hypoallergenic material (commercial medical tapes designed to adhere to skin). Microneedle patches will be administered topically by manual application to the skin. The sites of microneedle patch application will be cleaned with an alcohol swab and allowed to dry before the microneedle patch is applied. The microneedle patches will be packaged and provided as single patches.

  • Subject has used long-term\* high-dose\*\* oral or parenteral glucocorticoids, or high-dose inhaled steroids.\*\*\*
  • \* Long term is defined as taken for 2 weeks or more in total at any time during the past 2 months.
  • \*\* High dose defined as prednisone ≥ 20 mg total daily dose, or equivalent dose of other glucocorticoids.

  • Subject has a history of an underlying skin condition (e.g., eczema, atopic dermatitis) or an open lesion (e.g., laceration, abrasion), scar, or rash in the areas of the planned microneedle patch administration which will interfere with the assessment of reactogenicity.
  • Subject or family members have a history of keloid formation.
  • Subject has any condition that, in the opinion of the investigator, may put the subject at increased risk of harm, may cause the subject to be unable to meet the requirements or might otherwise interfere with evaluations required by the study.
