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

- Prior or active viral hepatitis B or C infection
- Females who are lactating or pregnant (for females who have started menstruating the possibility of pregnancy must be excluded by urine βHCG on-site within 24 hours prior to the GAD-Alum and etanercept administration, respectively)
- Males or females not willing to use adequate contraception, if sexually active, until 1 year after the last GAD-Alum and etanercept administration, respectively
- 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.
- Deemed by the investigator not being able to follow instructions and/or follow the study protocol
- 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
- Hypersensitivity to the active substance in Enbrel (etanercept) or other ingredients in Enbrel
- Active or inactive (latent) tuberculosis (TBC) at screening
- History of malignancy or significant cardiovascular disease
- Current or history of leukopenia, anemia and/or thrombocytopenia
- Liver disease (clinical or hepatic enzymes >3 times the upper limit of normal (ULN))

Group Intervention Description A Etanercept All patients will from Day 1 receive 2 000 IU vitamin D per os per day during 15 months, and from Days 1-90 receive etanercept (Enbrel) injected subcutaneously 0.8 mg/kg body weight (max 50 mg) once a week, and receive 2 subcutaneous injections of 20 μg Diamyd in a prime-and-boost regimen on Days 30 and 60. A GAD-Alum All patients will from Day 1 receive 2 000 IU vitamin D per os per day during 15 months, and from Days 1-90 receive etanercept (Enbrel) injected subcutaneously 0.8 mg/kg body weight (max 50 mg) once a week, and receive 2 subcutaneous injections of 20 μg Diamyd in a prime-and-boost regimen on Days 30 and 60. A Vitamin D All patients will from Day 1 receive 2 000 IU vitamin D per os per day during 15 months, and from Days 1-90 receive etanercept (Enbrel) injected subcutaneously 0.8 mg/kg body weight (max 50 mg) once a week, and receive 2 subcutaneous injections of 20 μg Diamyd in a prime-and-boost regimen on Days 30 and 60.
