SECONDARY outcome

Timeframe: 18 months

Measure liver function tests at 6 and 12 months and at 6 months after drug or placebo is stopped to ensure that no abnormalities (liver function blood tests outside of normal reference range) of liver function occur with the drug.

OTHER_PRE_SPECIFIED outcome

Timeframe: 1 week

Population: Biopsy samples were collected, but not sent for pathological analysis due to trial futility. There are no results available to report.

It is believed that the autoimmune assault of new onset type 1 diabetes leads to stress to the part of the beta cell that folds proteins; referred to as endoplasmic reticulum stress. When endoplasmic reticulum stress increases, changes in protein levels in beta cells occur. The investigators will measure markers of endoplasmic reticulum stress in beta cells taken from skin biopsies from subjects before treatment with TUDCA or placebo.
