4. High GADA titers (>190 U/ml)
5. Patients must be insulin independent at baseline by clinical judgement and C-peptide criteria
6. Antidiabetic medication in the form of metformin is acceptable for inclusion as well as medications not mentioned under exclusion criteria
7. Females must agree to avoid pregnancy, and must have a negative urine pregnancy test.
