简要总结

The objectives of this study is to

  • evaluate the safety and influence of treatment with GAD-Alum (Diamyd) combined with Vitamin D and Ibuprofen on preservation of residual insulin secretion in recently diagnosed Type 1 Diabetes
  • evaluate how the above mentioned treatments influence the immune system of the subjects and interact with any viral infections
  • evaluate the safety and influence of treatment with double dose of GAD-Alum (Diamyd) plus Vitamin D on the immune system, viral infections, and on preservation of residual insulin secretion in recently diagnosed Type 1 Diabetes

入选标准

  • Male and female patients between 10 and 18 years of age
  • Insulin dependent Type 1 Diabetes mellitus diagnosed within the previous 4 months at time of screening
  • Fasting C-peptide level at time of screening above or equal to 0.12 nmol/L
  • Elevated GAD65 antibodies (GADA) at time of screening

排除标准

  • Treatment with immunosuppressants, continuous anti-inflammatory drug, Vitamin D or any anti-diabetic medications other than insulin
  • A history of certain diseases or conditions (e.g. anemia, HIV, epilepsy, head trauma, neurological diseases or cerebrovascular accident, alcohol or drug abuse etc)
  • Treatment with any vaccine within 4 months prior to first planned administration of GAD-Alum/placebo or planned treatment with vaccine up to 4 months after the last injections with GAD-Alum/Placebo, including influenza vaccines
  • Participation in other clinical trials with a new chemical entity within the previous 3 months
  • Pregnancy or planned pregnancy within 1 year after the last GAD-Alum/placebo dose
  • Presence of associated serious disease or condition which in the opinion of the investigator makes the patient non-eligible for the study
