Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Type 1 diabetes is caused by an autoimmune destruction of the insulin producing cells of the pancreas. The investigators have discovered the specific autoimmune cells responsible for destroying the insulin-producing cells in an animal model of type 1 diabetes, and the means of destroying those cells.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The investigators are now aiming to use a similar strategy (vaccination with BCG, the vaccine used world-wide to protect against tuberculosis) in human type 1 diabetes to see if the abnormal immune cells can be depleted. This is the first step in trying to cure established type 1 diabetes.
