Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Multiple intradermal implants comprising of three treatments, 3 weeks apart, each consisting of 21 injections in total, each 5mm apart in a grid formation over a 3cm x 3cm area of the mid to deep dermis of the medial aspect of the upper arm. Each injection delivered by the treating doctor will consist of approximately 20ul of product delivered using a 30Gx1/4 inch needle. Each subject will receive ELAPR then Restylane (Registered Trademark) Vital Light (control) to the opposite arm following the same treatment regimen and using the same technique. The concurrent treatment will be administered every three weeks on Day 1, 22 and 43.

Outcomes
Primary outcome [1] 279914 0
To assess the persistence and tissue compatibility of ELAPR following dermal implantation for up to 26 weeks. A 4mm skin biopsy will be taken from each of the implant sites from Cohort A subjects (including replacements) on Day 169, and from Cohort B subjects (including replacements) on Day 85. The biopsy will encompass the needle point tattoo at the centre of the implant site. The biopsy site will be closed with a single stitch followed by standard aftercare procedures with stitch removal 7 to 10 days later.

26 weeks
Secondary outcome [1] 294767 0
To assess the acute and chronic safety of ELAPR. Safety evaluations will consist of monitoring and recording of all spontaneously reported and observed adverse reactions to the study device, general physical examination, clinical laboratory safety testing.
Timepoint [1] 294767 0
26 weeks
Secondary outcome [2] 294768 0
To assess the effects of ELAPR on skin elastin content, At each visit, subjects will be asked questions related to the status of implants, skin site texture and elasticity, skin reactions and any activities undertaken which may impact on the implant. Measurements of skin elasticity and skin thickness will be made using a Dermal Torque Meter (DTM) and skin calipers, respectively.

Secondary outcome [3] 294769 0
To assess the effects of ELAPR on skin elasticity and skin thickness.The physical presence of the implants will be assessed by the investigator at each visit by palpation.

Secondary outcome [4] 294770 0
To assess the effects of ELAPR on subjective comfort and feel of the implant using Visual Analogue Scales at before and one hour post treatment and at each follow-up visit.

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Following a screening period of up to 28 days, subjects who meet the entry requirements will be enrolled to one of two Cohorts, Cohort A or B and randomly assigned to receive treatment with one of two ELAPR formulations plus the control. The patients will be notified at the end of the study which treatment they were allocated to. The PI and study staff are Allocation is not concealed to the PI and study staff. All subjects will receive three treatments, 3 weeks apart.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Once the patient has the subject identification recorded on the enrollment log, they will be allocated into the treatment arms. Treatment allocation was devised by using a randomisation table from a treatment statistic book
The first group of eight patients (01 – 08) will have their biopsy performed at day 169. The second group of eight patients (09 – 16) will have their biopsy at day 85.
Patients with an even subject identification number (SIN) (02, 04, 06, 08, 10, 12, 14, 16) will have ELAPR to the right arm and the control to the left, where patients with an odd subject identification number (01, 03, 05, 07, 09, 11, 13, 15) will have the ELAPR to the left arm and the control to the right.
Patients will receive either device ELAPR002c or ELAPR002e. This will alternate as described to minimize bias between the right and left arms.
