Study Endpoints
Primary Endpoints
To assess the safety of the Cell Pouch following implantation, and islet transplantation, by evaluating the incidence and severity of adverse events (AEs) determined to be probable or highly probable to the Cell Pouch
365 days ±14 days

Safety will be assessed by evaluating the incidence and severity of adverse events (AEs) determined to be probable or highly probable to the Cell Pouch following initial Cell Pouch implantation, at the time of islet transplantation, and following islet transplantation, and throughout the study up to 365 days ±14 days post-islet transplantation

Secondary Endpoints
Survival of endocrine tissue in the Cell Pouch (defined by positive staining of islets during histological analysis)
90±5 days post-transplant for sentinel Cell Pouch
Proportion of participants with a reduction in severe hypoglycemic events
From Day 0 to 90±5 ; Day 90±5 to Day 180±5; Day 180±5 to Day 365±14 following final Cell Pouch transplant and/or last transplant
Proportion of participants with a reduction in HbA1c >1mg%
From Day 0 to 90±5 ; Day 90±5 to Day 180±5; Day 180±5 to Day 365±14 following final Cell Pouch transplant and/or last transplant

Sernova Cell PouchCOMBINATION_PRODUCTThe Sernova Cell Pouch will be implanted against the rectus abdominis. The patient will receive either an 8-plug or 10-plug Cell Pouch configuration depending on Cohort assignment. A minimum of three weeks after Cell Pouch implantation, immunosuppression will be initiated and optimized for another 3 weeks. This will allow for proper vascularization of the Cell Pouch chambers and the patient to be stabilized on immunosuppression prior to islet transplantation. A mass of highly purified islets will be transplanted in the Cell Pouch. Patients who elect to retain the Cell Pouch after completion of the study will be asked to consent to long term safety follow-up, with data collected beyond the study scheduled visits every 3 months for up to 5 years until the last Cell Pouch explant (and then for a minimum of 3 months thereafter).
