NCT02215200

Brief Summary

This is a three-arm, 1:1:1 randomized, placebo controlled, double- blinded trial in which at least 28 subjects will receive active Anti-Thymocyte Globulin and Granulocyte colony-stimulating factor (ATG-GCSF), at least 28 subjects will receive ATG alone and at least 28 subjects will receive placebo alone within 100 days from diagnosis of Type 1 Diabetes (T1D). The primary objective of the study will be to determine the safety and ability of low dose ATG plus GCSF and low dose ATG alone to retain/enhance C-peptide production in new onset T1D patients demonstrating residual beta cell function.

Outcome Measures

Primary Outcomes (1)

  • Change in Area Under the Stimulated C-peptide Curve From Baseline to 12 Months.

    The C-peptide 2 hour area under the curve (AUC) mean is calculated at baseline and 12 months and measured in nmol/L. The calculation for the concentration of c-peptide is a weighted average of the 6 timed measurements of c-peptide in nano-moles/Liter. We try to distinguish this calculation from the AUC by referring to it as the "AUC mean" and may be expressed algebraically as the AUC/(120 min.); thus, the units are the same as the y-axis").

    -10, 0 15, 30, 60, 90, and 120 minutes post-dose at baseline and 12 months

Study Arms (3)

Anti-Thymocyte Globulin (ATG) and Placebo

EXPERIMENTAL

Anti-Thymocyte Globulin (ATG)/Placebo: Anti-Thymocyte Globulin (ATG) will be administered at a dose of 2.5mg/kg as two divided IV infusions of 0.5mg/kg and 2mg/kg. First dose (0.5mg/kg) will be infused over a minimum of 12 hours, and the second dose (2mg/kg) over a minimum of 8 hours. The second dose should be given no less than 12 and no more than 24 hours after the previous dose. Placebo(for GCSF) treatment will begin 6 hours after completion of the ATG. Placebo will be given subcutaneously every 2 weeks for a total of 6 doses

Drug: Anti-Thymocyte Globulin (ATG)Drug: Placebo (for GCSF)

ATG plus Granulocyte colony stimulating factor (GCSF)

EXPERIMENTAL

Granulocyte colony stimulating factor (GCSF) is supplied in 0.6 mL prefilled syringes for subcutaneous injection. Each syringe contains 6 mg GCSF (based on protein weight), in a sterile, clear, colorless, preservative-free solution (pH 4.0) containing acetate (0.35 mg), sorbitol (30.0 mg), polysorbate 20 (0.02 mg), and sodium (0.02 mg) in water for injection, U.S. Pharmacopeial Convention (USP). The standard 6mg dose will be given with the exception of subjects who weigh less than 45 kg. GCSF treatment will begin 6 hours after completion of the ATG / Placebo. GCSF will be given subcutaneously every 2 weeks for a total of 6 doses

Drug: Anti-Thymocyte Globulin (ATG)Drug: Granulocyte colony stimulating factor (GCSF)

Placebo

PLACEBO COMPARATOR

Placebo for ATG will be administered by IV infusion in 2 doses. Placebo for GCSF will be administered subcutaneously every 2 weeks for a total of 6 doses
