Two-part, randomised, double-blind, placebo-controlled study in healthy participants to investigate the skin tolerability of micro-projection array patches coated with inactivated split influenza virus haemagglutinin (HA) from A/Singapore/GP1908/2015 (A/Michigan/45/2015(H1N1)-like) vaccine.

Brief summary

This study is designed to test the hypothesis that MAP application to the skin using a small number of healthy adult subjects with a well characterised influenza vaccine antigen (A/Singapore/GP1908/2015) results in comparable safety / local skin reaction to conventional intramuscular vaccination. This study represents the first time that polymer MAPs with an active vaccine will be applied to humans. Therefore, this study will assess both systemic and the local reaction to application of the A/Sing MAP delivering a 15 mcg HA intramuscular-equivalent dose with the application of three MAPs, in comparison to uncoated MAPs, intramuscular injection with Afluria Quadrivalent (delivering 15 mcg A/Sing HA) and intramuscular injection with 15 mcg A/Sing HA (as a monovalent antigen). The local skin response will be monitored for up to 60 days. On-site clinic assessments will be performed up to 2 hours post application and at 1, 3, 7, 21 and 60 days (if required) post application. Phone calls will be made at Day 36 and Day 50

Interventions

The study is in 2 parts,with 4 parallel treatment groups in Part A and 9 parallel treatment groups in Part B. In both study parts the interventional exposure group being studied is the Micro array projections (MAPs) coated with A/Singapore/GP1908/2015 antigen (A/Sing) in various doses. The comparator products are listed in the section below. The A/Sing MAP comes in 2 doses; 5mcg Haemagglutinin protein (HA) or 2.5 mcg HA. They are single use. For each subject, a MAP is applied for 2 mins then

The study is in 2 parts,with 4 parallel treatment groups in Part A and 9 parallel treatment groups in Part B. In both study parts the interventional exposure group being studied is the Micro array projections (MAPs) coated with A/Singapore/GP1908/2015 antigen (A/Sing) in various doses. The comparator products are listed in the section below. The A/Sing MAP comes in 2 doses; 5mcg Haemagglutinin protein (HA) or 2.5 mcg HA. They are single use. For each subject, a MAP is applied for 2 mins then removed then the next patch is applied for 2 mins then removed etc. The MAP is applied by a trained medical professional. Study Part A: Group 1 subjects will receive 3 x 5mcg A/Sing coated MAPs to the forearm, total dose 15mcg HA. Groups 2, 3 and 4 will receive comparator products (described in section below) Study Part B: Group 1 subjects receive 3 x 5mcg A/Sing coated MAPs to the forearm, total dose 15mcg HA Group 2 subjects receive 3 x 5mcg A/Sing coated MAPs to the forearm, total dose 15mcg HA and they will undergo additional testing of punch biopsy of application site. Group 3 subjects receive 2 x 5mcg A/Sing coated MAPs to the forearm plus 1 uncoated (placebo MAP, total dose 10mcg HA Group 4 subjects receive 1 x 5mcg A/Sing coated MAP to the forearm plus 2 uncoated (placebo MAPs, total dose 5mcg HA Group 5 subjects receive 1 x 2.5mcg A/Sing coated MAP (2.5mcg HA) plus 2 uncoated (placebo) MAPs to the forearm, total dose 2.5 mcg HA Group 8 subjects receive 3 x 5mcg A/Sing coated MAPs to the deltoid muscle, total dose 15 mcg HA The MAP delivery device is a hand-held mechanical, spring loaded, disposable applicator (Vaxxas Clinical Applicator, disposable, CAP) calibrated at a specific speed of 20 m/s. Each MAP will be delivered to the skin and left in situ for 2 minutes. It will then be removed by a gloved finger by gently tensioning the skin around the patch with one hand, whilst pulling the MAP directly up and away from the skin with the other hand.
