The Change in Clarke Score From Baseline in GLASSIA Treated Versus Control CIT06 Subjects
Clarke Score is a 7 question patient report of hypoglycemia awareness. Answers provide a rating of either A (aware) or R (reduced). Four or more R ratings suggest impaired hypoglycaemia awareness; \< or equal to 2 = normal awareness, 3=borderline. A higher Clarke Score indicates reduced awarness.

Cardiovascular Events [Death, Cerebrovascular Accident (CVA), Myocardial Infarction (MI)] and Changes in Atherogenic Profile for GLASSIA Treated Versus Control Subjects
Subjects experience of cardiovascular events and changes in atherogenic profile were examined for the timepoints listed below. Data utilized were baseline lipid labs (triglycerides, total cholesterol, HDL, LDL, and Non-HDL Cholesterol) and lipid labs taken at specified timepoints. An improvement would be an overall improvement of the lipid profile (e.g. reduction in non-HDL cholesterol/overall cholesterol, decrease in LDL, increase in HDL, etc.). Due to the COVID-19 pandemic and increased risk faced by transplant/immunosuppressed individuals, some lipid labs were not collected and data has been indicated as NA due to reduction in sample collection/prioritizing safety labs for subjects.
Time frame: 1 year and 2 years following the first and last islet transplant(s)
