Description of intervention(s) / exposure
NexoBrid is a bromelain-based enzymatic debriding agent that is well established in many European burn centres. It is a lyophilised, partially purified, proteolytic protein mixture with increased specific enzyme activity derived from Bromelain raw material extracted from pineapple stems.
In the pilot study, NexoBrid will be administered to mid- to deep dermal and full thickness burns of the upper limb.
Nexobrid will be administered topically in a single session by a specialist Burns Surgeon for a total of 4 hours with an occlusive dressing.
Eligible patients will be consecutively allocated into either the NexoBrid or SOC group.
Intervention code [1] 323175 0
Treatment: Other
Comparator / control treatment
Early surgical debridement followed by autologous skin grafting is considered to be the standard of care (SOC) internationally for the treatment of burn injury as it prevents early complications and minimises hypertrophic scarring.
Control group
Active

Summary
Brief summary
In this pilot study, NexoBrid will be administered and its effectiveness will be assessed compared to the current surgical standard of care (SOC). This study will recruit 10 patients with upper limb burns treated with NexoBrid compared to 10 patients with upper limb burns receiving the SOC. It is hypothesised that the use of NexoBrid on acute thermal upper limb burns will reduce the patient length of stay in hospital.
