New treatment option for Presymptomatic Diabetes Type 1 (Stage 1)
Official title Treatment of Presymptomatic (Stage 1) Type 1 Diabetes Pediatric Patients With Treg Cell Preparations and Anti-CD20 Antibody
ClinicalTrials.gov ID: NCT06688331
What this study is testing
What is ex vivo expanded CD4+CD25+CD127- regulatory T cells (Tregs)?
ex vivo expanded CD4+CD25+CD127- regulatory T cells (Tregs) is an investigational medicine, given as an infusion into a vein, being studied as a potential treatment for presymptomatic diabetes type 1 (stage 1).
Also referred to as Tregs, regulatory T cells.
Plain-language explanation of the investigational treatment - it is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- The main purpose of the study is to check: Can therapy with a preparation of regulatory cells (Tregs lymphocytes) and/or an anti-CD20 antibody preparation (rituximab) be successfully used in children with pre-diabetes to treat or delay type 1 diabetes? Is therapy with a preparation of regulatory cells (Tregs lymphocytes) and/or a preparation of antiCD20 antibodies (rituximab) safe for children with pre-diabetes, and what side effects may be associated with it?
- Phase 2: a mid-size study of how well it works
- You might receive a placebo (an inactive treatment) instead of the study drug, decided by chance. You may not know which one you got.
A plain-language read of the study's public ClinicalTrials.gov listing. The study team confirms the details.
