Type 1 Diabetes study: Anti-thymocyte globulin
Official title Precision Administration of Anti-thymocyte Globulin With or Without Verapamil
ClinicalTrials.gov ID: NCT06455319
What this study is testing
What is Anti-thymocyte globulin (ATG)?
This is an investigational medicine being studied as a potential treatment for Type 1 Diabetes. It is designed to target and reduce the activity of specific immune cells that may attack the body's insulin-producing cells.
Also referred to as Thymoglobulin.
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
- This study is testing whether a small amount of ATG can keep the body’s insulin working in people with newly diagnosed type 1 diabetes. It also looks at whether adding verapamil after ATG makes it work better.
- Who it's for
- You may be able to join if you are a person who was diagnosed with type 1 diabetes within the last year and are willing to try a new treatment.
- What's involved
- You would receive a low dose of ATG, and later you might take verapamil. You will have blood tests and other checks to see how your immune system and insulin cells are doing. The study will also look for a blood marker that predicts if ATG will help you.
- Time commitment
- The study lasts about one year, with several visits for blood tests and health checks throughout that time.
- 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.
