Trial of Otelixizumab for Adolescents and Adults With Newly Diagnosed Type 1 Diabetes Mellitus (Autoimmune): DEFEND-2 (DEFEND-2)
DEFEND-2 is a Phase 3 confirmatory study for the Phase 3 DEFEND-1 study. The study objective is to find out if an 8-day series of otelixizumab infusions leads to greater improvement in insulin secretion as compared with placebo. Insulin secretion will be assessed using mixed meal-stimulated C-peptide.
Subjects will be assigned to receive either otelixizumab or placebo at a ratio of 2:1 (2/3 otelixizumab, 1/3 placebo). These study agents will be administered as an addition to insulin, diet, and other standard of care treatments.

- Amount of C-peptide (a protein that shows how much insulin the body is producing) during a mixed meal stimulation test. [ Time Frame: at 12 months ] [ Designated as safety issue: No ]
- Average daily insulin use, HbA1c (a measurement of blood glucose control), and incidence of abnormal blood glucose levels. [ Time Frame: at Week 12, Months 6, 12, 18, and 24 ] [ Designated as safety issue: No ]
|Study Start Date:||May 2010|
|Study Completion Date:||March 2012|
|Primary Completion Date:||March 2012 (Final data collection date for primary outcome measure)|
Placebo Comparator: placebo
The following visits are required:
- Screening Visits: 2 to 3 appointments will be conducted to determine eligibility. At 2 of these visits participants will drink a liquid meal and have blood tests done over the post-meal period. Participants will also be required to wear a continuous glucose monitor for a short period of time.
- Dosing Visits: 8 outpatient visits on consecutive days, each lasting about 2-4 hours.
- Follow-up Visits: weekly for the first month, then every 2 weeks for 3 months, followed by monthly visits through 1 year. There will be 3 visits in the second year.
- The total duration of the study is 2 years.
- Glucose test strips and glucose monitors will be provided to participants for the duration of the study. Frequent glycemic monitoring will occur through lab testing and blood glucose self-monitoring to help facilitate tight glycemic control in all subjects. Subjects will be asked to intermittently record their insulin doses using a telephone or web based system and continuous glucose monitoring will be performed every 6 months.
