Interferon-Alpha for Diabetes Mellitus Type 1

Phase 2
Completed
Conditions
Insulin-Dependent Diabetes Mellitus
Interventions
Other: Placebo
Drug: 5,000 hrINF-alpha
Drug: 30,000 units hrINF-alpha
Registration Number
NCT00024518
Lead Sponsor
The University of Texas Health Science Center, Houston
Brief Summary

This study will see if interferon-alpha given early in the disease can stop or slow the immune attack on insulin-producing cells. In addition, the study will examine the safety and efficacy of interferon-alpha (given by mouth) to protect beta cell function. Patients between 3 and 25 years of age with Type 1 Diabetes Mellitus less then six weeks may be eligible for this study. All study-related tests and medications at the NIH Clinical Center are provided at no cost.

Detailed Description

Type 1 diabetes mellitus (T1DM) results from autoimmune destruction of the insulin-producing pancreatic beta-cells. The onset of clinical symptoms represents the endpoint of a chronic progressive decline in beta-cell function when the number of functional beta-cells descends below the critical mass required for maintenance of euglycemia (\[1\], \[2\]). However, the pancreas still retains the ability to produce a substantial amount of insulin. The goal of secondary prevention in T1DM is to avert further destruction of the remaining beta-cells and therefore delay or stop entry into the final stages of the disease associated with end organ damage.

The rationale for this study is to interfere with the autoimmune beta-cell destruction early on in order to preserve as much residual endogenous insulin production as possible. We plan to administer oral interferon-alpha (IFN-a) on a daily basis, which has been shown to modify the clinical course of diabetes, to alter cytokine release, and reduce expression of T cell activation markers in an animal model (\[3\]) and a pilot project in humans (S. Brod, University of Texas, unpublished data). The one-year study is designed as a double blind randomized protocol using either 5,000 or 30,000 units of IFN-a versus placebo. Five centers will participate in this protocol (University of Texas Health Science Center in Houston; Dallas; Children's Hospital, St. Paul, MN; Kansas City and NIH, Bethesda, Maryland).

Primary Outcome Measures
NameTimeMethod
C-Peptide LevelBaseline - 3mth, 6mnth, 9mnth, 12mnth

The Connecting Peptide, or C-peptide, is a short 31-amino-acid protein that connects insulin's A-chain to its B-chain in the proinsulin molecule.

Secondary Outcome Measures
NameTimeMethod
Serum glucosebaseline - 3mths, 6mnths, 9mnths, 12mnths

Serum glucose or blood sugar measurements determine how much sugar is in the blood.

Hemoglobin A1CBaseline - 3mnths, 6mnths, 9mnths, 12mnths

a form of hemoglobin that is measured primarily to identify the average plasma glucose concentration over prolonged periods of time.
