Health condition(s) or problem(s) studiedLatent autoimmune diabetes in adults.
InterventionTreatment with subcutaneous injections of DiaPep277 or placebo in three different treatment groups with different schedules for a period of approximately 18-20 months. Follow up until 2 years after the first administration of study drug.

Group A: Administration of 1 mg DiaPep277 or placebo at the start of the study and 1 month, 6 months, 12 months and 18 months later. In total five administrations.
Group B: Administration of 1 mg DiaPep277 or placebo at the start of the study and 2 weeks, 4 weeks, 6 weeks and 8 weeks later. Further administrations in intervals of approximately 3 months. In total 10 administrations.
Group C: Administration of 0.2 mg DiaPep277 or placebo at the start of the study and 2 weeks, 4 weeks, 6 weeks and 8 weeks later. This course is repeated 6 months, 12 months and 18 months after the first administration. In total 20 administrations.
