Description of intervention(s) / exposure
AWBAT is a second generation temporary epidermal replacement. It is to be compared with Biobrane (a first generation product with the same indications). Both materials are applied to meticulously cleaned superficial partial thickness burns under general anaesthesia in theatre. The piorcine peptide component in the materials stimulates the conversion of fibrinogen in the burn exudate to fibrin, firmly adhering the material to the burn. Both materials then stay in-situ until the burn re-epithelialises beneath. Both materials then spontaneously separate. The length of material adherence depends on the burn depth - very superficial 4-5 days, mid-dermal up to 14 days. All participants will receive both Biobrane and AWBAT thus acting as their own controls since Biobrane is the material we currently use routinely according to our surgical protocols.

Treatment: Devices
Comparator / control treatment
Biobrane (like AWBAT) contains fragments of porcine type 1 collagen which convert burn exudate fibrinogen into fibrin. Both materials work identically except the peptide fragments in AWBAT are less sterically obstructed, therefore the conversion (and thus adhesion) are quicker.All participants will receive both Biobrane and AWBAT thus acting as their own controls since Biobrane is the material we currently use routinely according to our surgical protocols.

Outcomes
Primary outcome [1] 240693 0
Length of stay
Timepoint [1] 240693 0
Daily from randomisation to discharge
Primary outcome [2] 240702 0
Rate of epithelialisation (although the length of stay is often not directly related to healing and more dependent on the ease of treating these patients as out-patients post-application). In burns of the depth studies, epithelialisation will be completed by day 14 at the latest.
Timepoint [2] 240702 0
Daily from randomisation until discharge.
Secondary outcome [1] 257332 0
Perceived pain measured according to Mayo Clinic Visual analogue scale.
Timepoint [1] 257332 0
Daily from randomisation until discharge. Additional measures may be made during therapy and procedures (dressing changes)

Eligibility
Key inclusion criteria
Superficial partial thickness burns
Two non-contiguous burn sites of the same approximate size/depth for comparison,
OR
One burn site large enough to accommodate both a 6” square AWBAT (Trademark) dressing AND a 6” square Biobrane (Registered Trademerk) dressing
Burn wounds ranging between 2% < Total Body Surface Area <40%
Minimum age
18 Years
Maximum age
70 Years
Sex
Both males and females
Can healthy volunteers participate?
Yes
Key exclusion criteria
Delayed presentation (>48 hours)
Ventilator dependence
Signs of burn wound infection
Pregnancy/Lactation
Electrical, chemical or frostbite injury
Non-English speakers (from an informed consent perspective)
Patient from a rural centre where there is a burns link-nurse (Port Pirie, Mount Gambier, Adelaide Hills, Gawler)
Co-morbidity which may compromise healing
Known allergy to porcine products

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Randomisation tables linked to sealed envelopes will be used.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
All patients meeting inclusion criteria and displaying no exclusion criteria will be approached to participate. Treatment allocation is per randomisation tables in study appendix (pertains to site to receive AWBAT vs site to receive Biobrane
Masking / blinding
Open (masking not used)
Who is / are masked / blinded?



Intervention assignment
Single group
Other design features
Patients receive both AWBAT and Biobrane to burns at separate sites or the same site (large area) thus acting as their own active control

Summary
Brief summary
Biobrane is our gold standard for superficial partial thickness burns. AWBAT is very similar but adheres more rapidly to the wound. This is the rate limiting step in healing and allowing theses patients to be treated as outpatients. The study aims to compare the two in rate of epithelialisation and pain perception (the other issue which keeps burn patients in hospital).
