Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The vaccine delivery device consists of two parts. The first part is the 1cm² patch that has a series of micro-projections that hold the vaccine coating (placebo in this study). The second part is an applicator device that holds the patch in place and applies it to the skin.
the study is in 2 parts: Part A will be completed before recruitment to part B starts. Subjects in part A cannot re enter into part B
Part A:
Group A: Twenty subjects receive six gas-jet coated High Density Micro Array patches (HD-MAPs): one on each of the volar forearm, upper arm (over the deltoid muscle), and posterior shoulder (over the upper trapezius muscle) on each side of the body. A trained user will apply a HD-MAP to each anatomical site on the side of the body of the subject’s dominant hand. The subject will self-administer a HD-MAP to each site on the opposite side of the body, at the same sites. All applications are for 30 seconds.
Part B:
Forty subjects receive six Micro jet (MJet) coated HD-MAPs: one on each of the volar forearm, upper arm (over the deltoid muscle), and posterior shoulder (over the upper trapezius muscle). On one side of the body MAP applications will be 30 seconds. For 20 of these subjects, MAP applications will be 10 seconds on the opposite side of the body. For 20 of these subjects MAP applications will be 2 seconds on the opposite side of the body. This will be determined sequentially.

There is no active vaccination delivered in this study

Outcomes
Primary outcome [1] 322193 0
Primary study endpoint (outcome)
• Number of subjects with SAEs deemed possibly, probably, or definitely related to treatment administration.
• Number of subjects with AEs deemed possibly, probably, or definitely related to treatment administration.
• Local skin response (erythema, oedema, redness extent, induration, skin flaking, application site visibility) and photo imaging thirty minutes post-application. Local skin response and other recorded adverse events will be assessed at Day 7 (±1 day). Any local skin responses still present at Day 28 (±2 days) will be followed up to resolution, or until the subject is lost to follow-up.
the outcome for Part A is the same as for Part B but with an increased number of subjects in part B

Statistical methods / analysis
All collected subject information will be included within subject listings and summarized in tables with treatment received (forearm, upper arm, and trapezius applications).
Treatment site reaction and skin irritation index will be summarised at each assessment time. Comparisons between degree of engagement and estimated delivery efficiency at sites of application will be analysed using appropriate statistical tests.
Descriptive statistics of demographics (age, height and weight at screening, race/ethnic origin) will be presented. Medical history information collected at screening will be listed. All adverse events will be listed by subject and will include details of the onset date and time, duration, severity, causality and treatment/medications administered.
Vital signs (blood pressure, heart rate, and oral temperature) will be listed by subject and summarised in tables by treatment group.
Physical examination data will be listed by subject.
Local reactions will be listed by subject and summarised in tables by treatment group.
Concomitant medications will be entered as Trade names and coded using the WHO DD according to the ATC codes. All medications will be listed by subject, start and stop date and time, end date and time, dose, route of administration and reason for administration.

Summary
Brief summary
The aim of this study is to assess the safety and performance of a new vaccine delivery device that uses a patch to deliver vaccines. This study will show how the device performs, whether patients could use it themselves to apply the patches, and how long the patch should be left on the skin. No vaccine is used in this study. A placebo coating on the patch is used to represent the vaccine.
