Phase 1 Study of BHT-3021 in Subjects With Type 1 Diabetes Mellitus

Phase 1
Completed
Conditions
Hypoglycemia
Diabetes
Interventions
Drug: BHT-Placebo
Registration Number
NCT00453375
Lead Sponsor
Bayhill Therapeutics
Brief Summary

The purpose of this study is to determine the safety of BHT-3021 injections given weekly for 12 weeks and to evaluate the effect of BHT-3021 on antibody and immune (T cell) responses to autoantigens (e.g. insulin). Changes in pancreatic beta cell function, insulin requirements and blood glucose levels will also be evaluated.

Detailed Description

Type 1 diabetes results from an attack by the body's own immune system on the insulin producing cells in the pancreas. Around 80% of diagnosed patients have detectable antibodies to islet cell self-proteins including, insulin IA-2 and glutamic acid decarboxylase. The drug, BHT-3021 is being studied because an agent that stops autoimmune damage could offer patients benefit.

Study Description: A Randomized, Blinded, Placebo Controlled, Safety and Pharmacodynamic Study of BHT-3021 with Open Label Cross-Over in Subjects with Type I Diabetes Mellitus that will enroll up to 72 subjects in this trial. Subjects will be randomized to BHT-3021 or BHT-placebo in a 2:1 ratio.

The duration of the study is approximately 25 to 37 months depending on treatment assignment: 4 week Screening Period; 12 month Blinded Treatment and Evaluation Period; 12 month Cross-over Treatment and Evaluation Period (BHT-placebo subjects only); 12 month Long Term Follow-Up period.
