Brief Summary:
The objective of DIAGNODE-2 is to evaluate the efficacy of Diamyd compared to Placebo, upon administration directly into a lymph node in combination with an oral vitamin D/Placebo regimen, in terms of preserving endogenous insulin secretion as measured by C-peptide.

The study is a 2-arm, randomized, double-blind, placebo-controlled, multicenter, clinical trial. Eligible patients will receive injections of Diamyd/placebo into an inguinal lymph gland at three occasions, with one month intervals in combination with an oral vitamin D/placebo regimen (starting 1 month ahead of injections) during 4 months. All patients will continue to receive intensive insulin treatment from their personal physicians during the whole study period. The patients will be followed in a blinded manner for a total of 15 months. All patients that have not performed the 15 months visit when the updated protocol is implemented, will be asked to participate in the Extension Study Period which includes an additional visit at month 24.

Exclusion Criteria:
- 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)
- Treatment with any oral or injected anti-diabetic medications other than insulin
- A history of anemia or significantly abnormal hematology results at screening
- A history of epilepsy, head trauma or cerebrovascular accident, or clinical features of continuous motor unit activity in proximal muscles

- Inability or unwillingness to comply with the provisions of this protocol
- A history of alcohol or drug abuse
