• Status: Completed
• Trial end date: 2006-07-01
• Target enrollment: 0
• Participant gender: All

Summary

This was a study designed to evaluate the efficacy of multiple doses of an investigational drug, NBI-6024, in adult (18 to 35 years of age) and adolescent (10 to 17 years of age) patients with new onset type 1 diabetes mellitus, on endogenous insulin production.

A total of 188 patients were enrolled in the study. The study was divided into three periods:

screening, treatment (comprising an induction phase and maintenance phase), and follow-up.

NBI-6024 was generally well tolerated and exhibits a benign safety profile, as there were no significant safety issues with NBI-6024 treatment. In summary, NBI-6024 did not demonstrate statistically significant efficacy compared with placebo.
