Brief summary
The study hypothesis is that XOMA 052 may inhibit beta-cell destruction and enhance beta-cell regeneration. The purpose of this study is to assess the effects of XOMA 052 on beta-cell function and insulin production.

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Change in beta-cell function as measured by change in C-peptide level during thd MMTT (Mixed meal tolerance test) at Day 112 compared to baseline (Day 0 pre-dose) | Day 0 pre-dose and Day 112 |
Secondary
| Measure | Time frame |
|---|---|
| Change in insulin requirements | Day -3 through Day 0 pre-dose and Day 109 through Day 112) |
| Change in HbA1c levels | Day 0 pre-dose and Day 112 |
| Change in fasting glucose | Day 0 pre-dose and Day 112 |
| Change in fasting glucagon and cortisol | Day 0 pre-dose and Day 112 |
| Safety assessed by pre- and post-treatment serial measurements of vital signs, clinical laboratory assessments, and treatment-emergent adverse events. | Day 0 (baseline) through Day 364 |
| Change in meal-stimulated GLP-1 and GIP | Day 0 pre-dose and Day 112 |
