Overview
What is the purpose of this study?
This study is the long-term extension of the PRV-031-001 (PROTECT)
study. PROTECT is a Phase 3, randomized, double-blind,
placebo-controlled, multinational, multi-center study to evaluate the
efficacy and safety of teplizumab, a humanized, anti-CD3 monoclonal
antibody, in children and adolescents ages 8 through 17 recently
diagnosed with type 1 diabetes (within 6 weeks of diagnosis) in which
approximately 300 participants were randomized at a ratio of 2:1 to the
teplizumab or placebo and received two courses of treatment administered
6 or 12 months apart with final follow-up at approximately 18 months
(78 weeks) after the first dose. The purpose of this extension study is to evaluate the long-term safety of teplizumab in participants who previously completed the PRV-031-001 (PROTECT) study for an additional 42 months of follow-up
THIS STUDY IS ENROLLING BY INVITATION ONLY -
This study is only enrolling participants who completed the PROTECT (PRV-031-001) study.
Description
What will happen during the study?
- Participants who complete the PROTECT study are invited to enroll in this observational, extension study to collect long-term safety and other clinical data. The decision to participate can be made within 12 months of completing the PROTECT study.
- No study drug will be administered during this extension study.
- Participants will continue to receive standard care for type 1 diabetes from their primary physicians.
- Participants will return to the study sites for assessments once every 6 months through Month 42. Therefore, the combined duration of the PROTECT and PROTECT Extension studies will be 60 months.
