A Phase III Study to Investigate the Impact of Diamyd in Patients Newly Diagnosed With Type 1 Diabetes (EU) - Full Text View

Purpose

The purpose of this study is to determine whether Diamyd (rhGAD65 formulated in alum) is effective in preserving the body's own insulin producing capacity in patients recently diagnosed with type 1 diabetes.
