Diabetes Mellitus, Type 1 Clinical Trial

Official title: MELD-ATG: Phase II, Dose Ranging, Efficacy Study of Anti-thymocyte Globulin (ATG) Within 6 Weeks of Diagnosis of Type 1 Diabetes (T1D)

Status Active, not recruiting

Clinical Trial Summary

This study has been set up within the framework of the INNODIA network. INNODIA is a global partnership between 31 academic institutions, 6 industrial partners, a small sized enterprise and 2 patient organizations, bringing their knowledge and experience together with one common goal: "To fight type 1 diabetes". (www.innodia.eu) The overall aim of INNODIA is to advance in a decisive way how to predict, stage, evaluate and prevent the onset and progression of type 1 diabetes (T1D).

For this, INNODIA has established a comprehensive and interdisciplinary network of clinical and basic scientists, who are leading experts in the field of T1D research in Europe and UK (United Kingdom), with complementary expertise from the areas of immunology, Beta-cell biology, biomarker research and T1D therapy, joining forces in a coordinated fashion with industry partners and two foundations, as well as with all major stakeholders in the process, including regulatory bodies and patients with T1D and their families.

The MELD-ATG trial is a phase II, Multi-centre, randomised, double-blind, placebo-controlled, Multi-arm parallel cohort trial.

• to investigate the effect of 2.5 mg/kg og ATG on the preservation of stimulated C-peptide at 12 months compared to placebo

• to identify the minimally effective dose of ATG that shows an effect on C-peptide when compared to placebo at 12 months

Clinical Trial Description

A phase II, Multi-centre, randomised, double-blind, placebo-controlled, Multi-arm parallel cohort trial.

Randomisation wil be stratified by age. The trial consist of seven cohorts. The first cohort of 30 participants will be randomised to placebo, 2.5 mg/kg, 1.5 mg/kg, 0.5 mg/kg and 0.1 mg/kg.

ATG total dose in a 1:1:1:1 allocation ratio. There will be an initial age step down selection of this cohort with recruitment starting with dose aged 12-25 years and, providing no new safety concerns are raised in the first 10 participants to receive active dose, progressing to all ages (5-25 years) The next two cohorts of 12 participants will be randomised to placebo, 2.5 mg/kg, and 2 specified middle ATG total doses in a 1:1:1:1 allocation ratio.

The next four cohorts of 15 participants will be randomised to placebo, 2.5 mg/kg, and a single selected middle ATG total doses in a 1:1:1 allocation ratio.

This design allows sequential adjustment of the middle doses to be explored following review of all safety and early efficacy data by the Independent Data Monitoring Committee ( IDMC) and Dose Determine Committee (DDC) to seek the minimum effective dose ;
