Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Polyacrolein polyethylene glycol oligomer mixture (0.045 gram/gram) will be administered topically as a spray solution to saturate the wound over a 14 day treatment period.

The first ten participants will be allocated to daily application; in practical terms this will mean at least five applications within the first seven days of treatment. The next twenty participants will be allocated to three times a week application. Dressing changes will be aligned with antibiotic application.

During each outpatient clinic visit, the burn wound site will be assessed clinically and study assessments completed. Thereafter, as needed, irrigation and debridement of the wound will be performed in accordance with the standard Burns Unit procedures avoiding chlorhexidine and other cleansing agents with residual effect.

Antibiotic will be administered by a dressing clinic nurse. The antibiotic will be sprayed onto the whole of the infected burn ulcer until the wound is visibly wet/saturated throughout. The wound will be then left open until visibly dried or for at least five minutes before applying a dressing. This will be to ensure adequate absorption of the topical antibiotic into the burn wound bed, to prevent immediate uptake into dressings and maximise the clinical efficacy of this antimicrobial preparation. The wound will then be covered using a standard foam dressing.

Adherence to the intervention will be monitored with records of the number of dressings attended, the number of antibiotic administrations and the number of pumps delivered.

All the procedures, including opening the wound, irrigation, debridement, the preparation and application of the topical antibiotic, and re-dressing, should take approximately 15 min to complete.

Statistical methods / analysis
Statistical analysis will be descriptive providing details of the clinical characteristics and microbiology of the infected wounds as well as the outcomes (clinical or toxicity) at the end of therapy, and also 2 weeks thereafter. Analysis of the primary outcome will be conducted using all participants that have received at least one dose of the study drug. Pre-defined sub-group analysis will separate (1) daily and three times a week dosing intervals; (2) early and late burn wound infections with late being greater than 6 weeks from date of injury. We consider a desirable outcome of this novel therapy to be at least 70% complete response, which would be a clinically significant improvement to the previously reported 50% response rate.

Summary
Brief summary
Burn wound infections continue to cause significant health problems for patients following a range of burn injuries. Current therapeutic options are sub-optimal and are often associated with delayed wound healing. We therefore plan to study the antibiotic, RECCE®327 to assess the clinical effectiveness and safety of this agent for the treatment on infected chronic burn ulcers. The study is exploratory and will deliver the new RECCE®327 antimicrobial via an innovative spray-on formulation, specially developed for this study. We plan to study two dosing schedules with ten participants receiving daily and a further twenty receiving three times a week application of the spray-on RECCE®327 antibiotic, over a 14 day study period. If this exploratory study suggests clinical effectiveness and no toxicity signal, we then plan to undertake a much larger study of the novel RECCE®327 antibiotic comparing it to standard care.
