New Onset of Type 1 Diabetes Mycophenolate Mofetil-Daclizumab Clinical Trial

Study Summary

The objective of this study is to identify immune intervention strategies that will preserve residual beta cell function at the onset of type 1 diabetes. Scientific evidence developed over the last 10 - 20 years suggests that type 1 diabetes is a chronic, slowly progressive autoimmune disease and that clinical symptoms do not develop until at least 80% - 90% of beta cell mass has been destroyed as a result of the autoimmune process. It is now recognized that preservation of remaining beta cells is clinically important as the ability to secrete, even small amounts of insulin, can make the disease easier to control and help minimize complications associated with having years of inadequate glycemic control. This clinical trial is the first in a series of studies to be launched by the TrialNet Study Group to test various interventions for preserving residual beta cell function in new onset type 1 diabetes. Specifically, this study is designed to determine the ability of Mycophenolate Mofetil (MMF/CellCept) used alone, or in combination with Daclizumab (DZB/Zenapax) to see if it is possible to stop the immune system from destroying beta cells in new onset type 1 diabetes patients (within 3 months of diagnosis.) Researchers have made great strides in understanding how the immune system works and in changing the activity of immune cells with medicines called immunotherapies. Some immunotherapies work by making the immune system less active. Scientists have discovered that key immune cells, called T cells, help to cause type 1 diabetes. These T cells are largely responsible for attacking the beta cells that produce insulin. Doctors have found medicines that slow or suppress the activity of T cells. It is hoped that these immunosuppressive medicines can help treat type 1 diabetes by stopping T cells before they destroy all of the beta cells. Medicines that make the immune system less active have been developed and studied for other diseases. Mycophenolate mofetil (MMF) an

Primary Outcome

The primary outcome is the area under the stimulated C-peptide curve (AUC) based on data collected at time 0 to 2 hours of a 4-hour mixed meal glucose tolerance test (MMTT) conducted at the primary endpoint visit. The timed measurements are done at: 0, 15, 30 60, 90, and 120 minutes.
