  8. Patients must follow the Swedish vaccination programme
  9. Patients of childbearing potential must agree to using adequate contraception, if sexually active, until 1 year after the last administration of GAD-alum and etanercept. Adequate contraception is as follows:

For females of childbearing potential:

  1. oral (except low-dose gestagen (lynestrenol and norethisterone), injectable, or implanted hormonal contraceptives (females)
  2. intrauterine device (females)
  3. intrauterine system (for example, progestin-releasing coil) (females)

For males of childbearing potential:

a. Condom (male)

Exclusion Criteria
  1. Previous or current treatment with immunosuppressant therapy (although topical or inhaled steroids are accepted)
  2. Continuous treatment with anti-inflammatory drug (sporadic treatment e.g. because of headache or in connection with fever a few days will be accepted)

  17. Males or females not willing to use adequate contraception, if sexually active, until 1 year after the last GAD-Alum and etanercept administration, respectively
  18. Presence of associated serious disease or condition, including active skin infections that preclude subcutaneous injection, which in the opinion of the investigator makes the patient non-eligible for the study.
  19. Deemed by the investigator not being able to follow instructions and/or follow the study protocol
  20. Active infection, including chronic and local infection or a history of previous tendency to serious infections, recent or ongoing uncontrolled bacterial, viral, fungal or other opportunistic infections, or known infection with active EBV or CMV
  21. Hypersensitivity to the active substance in Enbrel (etanercept) or other ingredients in Enbrel

  28. Arrhythmia
  29. Pancreatitis
  30. Vitamin D serum levels >100 nmol/L at screening
