What this trial studies

This clinical trial investigates the safety and efficacy of autologous regulatory T cell therapy in patients with Type 1 Diabetes Mellitus (T1DM). The study aims to address the immune dysfunction associated with T1DM by utilizing ex vivo expanded human autologous Tregs, which are designed to restore immune tolerance to pancreatic beta cells. Participants will undergo a modified preparation protocol for Tregs, and their responses will be monitored throughout the trial. The study is conducted at The Affiliated Nanjing Drum Tower Hospital, focusing on a specific patient population aged 8 to 65 years.

Who should consider this trial

Good fit: Ideal candidates are individuals aged 8 to 65 years diagnosed with Type 1 Diabetes and showing specific autoimmune markers.

Not a fit: Patients with uncontrolled diabetic ketoacidosis, severe allergies, or other significant health conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this therapy could help restore insulin production and improve blood sugar control in patients with Type 1 Diabetes.

How similar studies have performed: Previous studies have indicated potential therapeutic effects of autologous Treg transplantation in Type 1 Diabetes, suggesting this approach may be promising.
