Study of the Effects of XOMA 052 on Insulin Production in Subjects With Well Controlled Type 1 Diabetes
A Randomized, Double-blind, Placebo-controlled, Phase 2 Study of the Effects of XOMA 052 on Insulin Production in Subjects With Well-controlled Type 1 Diabetes
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.
