  Purpose
This is a randomized placebo controlled study to test whether a single 14 course of treatment with the anti-CD3 monoclonal antibody, hOKT3gamma1(Ala-Ala),Teplizumab will prevent the loss of insulin secretory capacity in individuals with Type 1 diabetes of 4 - 12 months duration since diagnosis.

Condition Intervention Phase
Type 1 Diabetes Mellitus Drug: mAb hOKT3gamma1(Ala-Ala), Teplizumab Drug: Placebo Arm Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Triple (Participant, Care Provider, Investigator)
Primary Purpose: Treatment
Official Title: Phase II Trial of hOKT3gamma1(Ala-Ala) Teplizumab for Treatment of Patients With Recent Onset Type 1 Diabetes

Primary Outcome Measures:
  • C-peptide Area Under the Curve (AUC) Response to a Mixed Meal Tolerance Test (MMTT) at 12 Months [ Time Frame: At month 12 post-treatment ]

    C-peptide secretory response was calculated as ln[(Area Under the Curve of the C-peptide from the 240 minute MMTT/240 +1]

    For presentation, the C-peptide data were converted to the AUC as pmol/ml. This is adjusted for baseline.


  • C-peptide Area Under the Curve (AUC) Response to a Mixed Meal Tolerance Test (MMTT) at Baseline [ Time Frame: At Baseline (before treatment) ]

    C-peptide secretory response was calculated as ln[(Area Under the Curve of the C-peptide from the 240 minute MMTT/240 +1]

    For presentation, the C-peptide data were converted to the AUC as pmol/ml. This baseline data was used to adjust for the C-peptide AUC primary endpoint measure at 12 months.



Secondary Outcome Measures:
  • Hemoglobin A1c [ Time Frame: At 12 months post-treatment ]
  • Average Insulin Use Over 12 Months [ Time Frame: After 12 months post-treatment ]
  • Baseline Insulin Use [ Time Frame: At baseline (before treatment) ]
  • Baseline Hemoglobin A1c [ Time Frame: At baseline (before treatment) ]

Arms Assigned Interventions
Experimental: 1
The course of Teplizumab comprises daily doses of 51 µg/m2, 103 µg/m2, 207 µg/m2, 413 µg/m2, and 10 of 826 µg/m2 over a 14 day treatment period.
Drug: mAb hOKT3gamma1(Ala-Ala), Teplizumab
This is a randomized, two-arm, double blind placebo controlled phase II trial in which 60 participants with recent-onset T1DM are randomized at a 1:1 ratio to receive Teplizumab or placebo over a 14 day treatment period. The course of Teplizumab comprises daily doses of 51 µg/m2, 103 µg/m2, 207 µg/m2, 413 µg/m2, and 10 of 826 µg/m2.
Other Name: mAb hOKT3gamma1(Ala-Ala), MGA031, Teplizumab
Placebo Comparator: 2
Normal saline infusion
Drug: Placebo Arm

Detailed Description:
The study design is a double blind placebo controlled trial that will enroll subjects between the ages of 8 - 30 who have had the diagnosis of Type 1 diabetes made 4 - 12 months prior to enrollment. A single 14 course of treatment with mAb hOKT3gamma1(Ala-Ala), Teplizumab will be given. The primary endpoint is the C-peptide response to a mixed meal at 12 months. A total of 60 subjects will be enrolled (30 in the drug treatment and 30 in the placebo groups) at 4 study sites: Yale University,the University of California at San Francisco, Children's Hospital of Philadelphia, and the Barbara Davis Diabetes Center.
