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.

Detailed description

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.

Inclusion criteria

1. Informed consent given by patients and/or patient's parent(s) or legal acceptable representative(s) (guardian(s)) according to national regulations 2.

Patients of childbearing potential must agree to use adequate contraception, until one (1) year after the last administration of Diamyd. Adequate contraception is as follows: For females of childbearing potential: 1. oral (except low-dose gestagen (lynestrenol and norestisteron)), injectable, or implanted hormonal contraceptives 2. combined (estrogen and progestogen containing) 3. oral, intravaginal or transdermal progesterone hormonal contraception associated with inhibition of ovulation 4. intrauterine device 5. intrauterine hormone-releasing system (for example, progestin-releasing coil) 6. bilateral tubal occlusion 7. vasectomized male (with appropriate post vasectomy documentation of the absence of sperm in the ejaculate) 8. male partner using condom 9. abstinence from heterosexual intercourse For males of childbearing potential: 1. condom (male) 2. abstinence from heterosexual intercourse

Exclusion criteria
