Brief Summary

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

The purpose of this study is to determine what corticosteroid receptor (and the dose of) is responsible for cortisol inducing hypoglycemia associated autonomic dysfunction in Type 1 DM. Specifically, we aim to determine whether stimulating the type 1 corticosteroid receptor (via fludrocortisone), the type 2 corticosteroid receptor (via dexamethasone), or both causes hypoglycemia associated autonomic dysfunction in Type 1 DM.

Participants

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

1

Day 1 hyperinsulinemic euglycemic clamps with either 0.2 mg fludrocortisone, 0.75 mg Dexamethasone, or both given orally before each morning and afternoon clamp. Day 2 hyperinsulinemic hypoglycemic glucose clamp.

Group Type EXPERIMENTAL

Fludrocortisone

Intervention Type DRUG

Oral Fludrocortisone 0.2 mg x 2 prior to each experimental period on Day 1

2

Fludrocortisone will be administered in doses of 0.05mg, 0.1mg and 0.2 mg form at the start of each clamp period on day 1. Dexamethasone will be administered orally in the doses of 0.18 mg, 0.375mg and 0.75mg doses. The combination of the 0.05mg fludrocortisone and 0.18mg dexamethasone and 0.1mg of fludrocortisone and 0.375 mg doses will be administered at the start of each day 1 clamp period. Day 2 90 minutes of moderate exercise.

Group Type EXPERIMENTAL

Dexamethasone

Intervention Type DRUG
