A Study of Saxagliptin in Subjects With Type 2 Diabetes Who Have Inadequate Blood Sugar Control With Sulfonylureas

Phase 3
Completed
Conditions
Diabetes
Interventions
Registration Number
NCT00313313
Lead Sponsor
AstraZeneca
Brief Summary

The purpose of this trial is to understand if adding saxagliptin to a sulfonylurea is safe and works better than increasing the amount of sulfonylurea a patient takes

Detailed Description

All subjects will participate in a lead-in period, and qualifying subjects will continue into a short-term randomized treatment period. Subjects who complete the short-term period will be eligible to enter the long term extension period. Also, subjects in the short-term period who have an elevated blood sugar that requires additional medication for blood sugar control (defined as rescue) will be eligible to enter the long-term treatment extension period where they will receive metformin.Rescue treatment with metformin is also available during the long-term extension period for subjects who meet glycemic criteria.
