Protege Extension Trial - Long Term Follow Up Trial for Subjects Who Completed the Protege Study (CP-MGA031-01)

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

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.

Pediatric Quality of Life Questionnaire Total ScoreMonth 6The 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.

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.
