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.

Primary Outcome Measures:
  • 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) [ Time Frame: Day 0 pre-dose and Day 112 ]

Secondary Outcome Measures:
  • Safety assessed by pre- and post-treatment serial measurements of vital signs, clinical laboratory assessments, and treatment-emergent adverse events. [ Time Frame: Day 0 (baseline) through Day 364 ]
  • Change in insulin requirements [ Time Frame: Day -3 through Day 0 pre-dose and Day 109 through Day 112) ]
  • Change in HbA1c levels [ Time Frame: Day 0 pre-dose and Day 112 ]
  • Change in fasting glucose [ Time Frame: Day 0 pre-dose and Day 112 ]
  • Change in fasting glucagon and cortisol [ Time Frame: Day 0 pre-dose and Day 112 ]
  • Change in systemic inflammation markers [ Time Frame: Day 0 pre-dose and Day 112 ]
  • Change in meal-stimulated GLP-1 and GIP [ Time Frame: Day 0 pre-dose and Day 112 ]
  • Change in lipids profile [ Time Frame: Day 0 pre-dose and Day 112 ]
  • Measurement of serum concentrations of XOMA 052 [ Time Frame: Day 0 pre-dose, Day 28, Day 56, Day 84, Day 112, Day 182, and Day 364 ]
