Primary

MeasureTime frame
Secondary Objective: The secondary objectives of the extension study are to: 1) assess long-term efficacy; 2) measure anti-teplizumab antibody levels; and 3) assess PRO (Patient Reported Outcomes).;Main Objective: 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.;Primary end point(s): Safety Endpoints Safety endpoints will include the number and percentage of subjects who experience an SAE, AESI, or other IRE. Efficacy Endpoints With regard to HbA1c levels and total daily insulin use, efficacy endpoints will include: • the proportion of subjects who have a total daily insulin dose <0.5 U/kg/day and an HbA1c level <6.5%; • the proportion of subjects who have a total daily insulin dose <0.5 U/kg/day and an HbA1c level <7.0%; • the proportion of subjects who have a total daily insulin dose <0.5 U/kg/day; • the proportion of subjects with an HbA1c level <6.5%; • the proportion of subjects with an HbA1c level <7.0%; and • mean HbA1c levels within each treatment group.
