Description of intervention(s) / exposure
This study is prospective, non-controlled, pilot proof-of-concept study of safety and design property achievement. It is a combination of two clinically approved products; cadaveric islets - transplanted into the liver for treatment of hypoglycemic unaware type 1 diabetics with poorly controlled disease and the Biodegradable Temporizing Matrix (BTM) - a synthetic polymer approved for the treatment of full thickness burns.
In combination, the BTM is implanted into a surgically created wound (approximately 10X4cm elliptical wound) in the inter-biceps/triceps groove of the medial arm in the trial participant. Then following a period of integration (>17 days) cadaveric islets from a consented organ donor are transplanted into the newly created hypervascular site (an alternative to the intrahepatic site).
The wound creation and BTM implant will be performed by a burns sugeon (Royal Adelaide Hospital) who has many years experience performing similar surguries to treat full thickness burns using the BTM. It is anticipated this process will take less than a hour to complete.
The islet transplant process will take less than 1 hour to complete and will be performed by the Islet transplant scientist, who has over 10 years experience performing islet transplants within the Nationally Funded Centres - Islet transplant program at the Royal Adelaide Hospital.
Wound site and BTM integration will be monitored at dressing changes and photographed to document progress.

Efficacy
Statistical methods / analysis
This is a pilot study and the recruitment number is small (5). However, some statistical significance may be produced and will be determined by analysis of variance (ANOVA), multiple logistic regression analysis, and by independent t-tests corrected for the numbers of comparisons, as appropriate for the data set. The two-sided probability level of 0.05 will be used as the criterion for significance.
