Brief summary
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).
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.

(EQ-5D) | Month 6 | The EQ-5D is a self-reported survey that measures quality of life across 5 domains: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. Each dimension is scored on a 3-level severity ranking that ranges from no problems, some problems, and extreme problems. The lowest possible score is 5 and the highest possible score is 15. Lower scores indicate better quality of life. |

Lower scores indicate better quality of life. |
| Pediatric Quality of Life Questionnaire Total Score | Month 6 | The 23-item PEDs QL generic core scales were designed to measure the core dimensions of health (physical, emotional, social and school functioning). Answers are scored from 0 meaning never to 4 meaning almost always. Lower scores indicated higher quality of life. Items on the questionnaire were reversely scored and linearly transformed to a 0-100 scale, so that higher scores indicated better patient reported outcome. The mean was computed as the sum of the items over the number of items answered (to account for missing data). If more than 50% of the items in the scale were missing, the score was not computed. |

Mean Values for Participant-reported Outcomes on the 5-dimension European Quality of Life Questionnaire. (EQ-5D)
The EQ-5D is a self-reported survey that measures quality of life across 5 domains: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. Each dimension is scored on a 3-level severity ranking that ranges from no problems, some problems, and extreme problems. The lowest possible score is 5 and the highest possible score is 15. Lower scores indicate better quality of life.

Pediatric Quality of Life Questionnaire Total Score
The 23-item PEDs QL generic core scales were designed to measure the core dimensions of health (physical, emotional, social and school functioning). Answers are scored from 0 meaning never to 4 meaning almost always. Lower scores indicated higher quality of life. Items on the questionnaire were reversely scored and linearly transformed to a 0-100 scale, so that higher scores indicated better patient reported outcome. The mean was computed as the sum of the items over the number of items answered (to account for missing data). If more than 50% of the items in the scale were missing, the score was not computed.

Proportion of Subjects in Segment 2 With Both a Total Daily Insulin Dose of Less Than 0.5 U/kg/Day and Hemoglobin A1c (HbA1c) Level of Less Than 6.5%.
Time frame: Month 6
Population: Because the study was terminated early with a limited number of subjects and subject visits, the data are only summarized. Too few data are available for meaningful analysis.
