Participant Flow

Recruitment Details	Thirteen Clinical Centers at academic institutions recruited and enrolled 126 subjects ages 8 to 45 years with autoimmune T1D for less than 3 months.
Pre-assignment Details	Subjects were screened for evidence of autoantibodies and c-peptide >0.2 pmol on a stimulated 2 hr Mixed Meal Tolerance Test to determine eligibility for the study.The MMTT must be conducted at least 21 days from the diagnosis of diabetes and no more than one month (37 days) prior to the date of randomization.

Outcome Measures

1. Primary Outcome

Title	Mean Stimulated C-peptide Area Under the Curve
Description	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.
Time Frame	2 years

Outcome Measure Data

Analysis Population Description

Participants who completed a 4-hour mixed meal glucose tolerance test at the two-year visit were included in the analysis

Statistical Analysis 1

Statistical Analysis Overview	Comparison Group Selection	MMF and DZB, Placebo Control
	Comments	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.
