Brief Summary:

The primary objective of this clinical investigation is to investigate the safety of implantation of the human islet containing device Beta-Air in type 1 diabetic subjects.

The secondary objective of this clinical investigation is to investigate if the transplantation of macro-encapsulated human islets within the Beta-Air device can provide improved glycaemic control in type 1 diabetes patients with reduced incidences of hypoglycaemic episodes.

  2. 2. Delta changes in insulin requirement/kg body weight at 1, 2, 3, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24 and 26 weeks post-transplantation when compared to before transplantation and 6 months after explantation [ Time Frame: 0-365 days ]
  3. 3. Delta changes in glycosylated hemoglobin (HbA1c) at 2, 4, 8, 12, 14, 18 and 26 weeks post-transplantation when compared to before transplantation and 6 months after explantation. [ Time Frame: 0-365 days ]
  4. 4. Delta changes in P-fructosamine at 2, 4, 8, 12, 18 and 26 weeks post-transplantation when compared to before transplantation and 6 months after explantation. [ Time Frame: 0-365 days ]
  5. 5. Delta changes in glucose variability and hypo/hyper glycaemia duration derived from a continuous glucose monitoring system performed at 12 and 26 weeks post-transplantation when compared to before transplantation and 6 months after explantation. [ Time Frame: 0-365 days ]
  6. 6. Quality of Life in transplanted patients at 12 and 26 weeks post-transplantation when compared to before transplantation and 6 months after explantation. [ Time Frame: 0-365 days ]
  7. 7. Score in diabetes treatment satisfaction questionnaire in transplanted patients at 12 and 26 weeks post-transplantation when compared to before transplantation and 6 months after explantation. [ Time Frame: 0-365 days ]
