Purpose
The purpose of this study is to assess the long term safety and efficacy in subjects with Type 1 Diabetes Mellitus who completed the Protege Study (CP-MGA031-01).
| Condition | Intervention | Phase |
|---|---|---|
|
Type 1 Diabetes Mellitus |
Drug: Teplizumab |
Phase 2 Phase 3 |
| Study Type: | Interventional |
| Study Design: | Allocation: Randomized Endpoint Classification: Safety/Efficacy Study Intervention Model: Parallel Assignment Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor) Primary Purpose: Treatment |
| Official Title: | An Extension of Study CP-MGA031-01 to Evaluate the Long-Term Efficacy and Safety of Teplizumab (MGA031), a Humanized, FcR Non-Binding, Anti-CD3 Monoclonal Antibody, in Patients With Recent-Onset Type 1 Diabetes Mellitus |
- Primary outcome measures will include the number and percentage of subjects who experience a SAE, Adverse Event of Special Interest (including Opportunistic Infection, Lymphopoliferative disease), or other Immediately Reportable Event. [ Time Frame: Duration of the study- 3 years ] [ Designated as safety issue: Yes ]
- A secondary endpoint will be determining the efficacy of teplizumab by measuring the subject's total daily insulin usage and HbA1c levels. [ Time Frame: Month 6, 12, 18, 24, 30, 36 ] [ Designated as safety issue: No ]
- C-peptide secretory response will be analyzed in terms of basal levels of C-peptide produced before a mixed meal and stimulated levels after a mixed meal, measured as AUC and peak post-meal production. [ Time Frame: Month 6, 12, 18, 24, 30, 36 ] [ Designated as safety issue: No ]
- Immunophenotyping of blood mononuclear cells will be summarized by visit and graphed over time, as appropriate. [ Time Frame: Month 6, 12, 18, 24, 30, 36 ] [ Designated as safety issue: No ]
- A secondary efficacy endpoint will be assessing Heath Related Quality of Life Questionnaires filled out by subjects at different timepoints in the study. [ Time Frame: Month 6, 12, 18, 24, 30, 36 ] [ Designated as safety issue: No ]

|---|---|
|
Experimental: 1 Active
Protege had 4 study arms, 3 were dosed with different doses of teplizumab, and 1 was a control group given placebo. This Extension study will continue to assess the subjects from these 4 arms. In Protege: Experimental Drug: Teplizumab, IV dosing daily for 14 days times 2 courses |
Drug: Teplizumab
No additional drug or placebo will be administered in this study. Blood will be drawn every 6 months after the last visit of the Protege Study for 3 years. Blood will be collected for chemistry, hematology, thyroid function, immunology, serology, autoantibodies, and metabolic function.

Detailed Description:
The primary objective of the extension study is to assess long-term safety, with particular focus on the development of serious adverse events (SAEs), adverse events of special interest (AESIs) including opportunistic infections and lymphoproliferative disease, and other immediately reportable events (IREs), in subjects with recent-onset T1DM who complete CP-MGA031-01.
The secondary objectives of the extension study are to: 1) assess long-term efficacy; 2) evaluate immunological effects(North America only); 3) measure anti-teplizumab antibody levels;4) assess Health Related Quality of Life Questionnaires.
