GAD-Alum (Diamyd) Administered Into Lymph Nodes in Combination With Vitamin D in Type 1 Diabetes (DIAGNODE-1) (DIAGNODE)
Open Label Pilot Trial in Adults With Recent-onset T1D to Evaluate the Safety, Diabetes Status and Immune Response of GAD-antigen (Diamyd®) Therapy Administered Into Lymph Nodes in Combination With an Oral Vitamin D Regimen
The objectives of the main study is to:
- Evaluate the safety of giving GAD-Alum (Glutamic acid decarboxylase) (Diamyd) directly into lymph glands in combination with an oral vitamin D regimen
- Evaluate how the above mentioned treatments influence the immune system and endogenous insulin secretion.
The objective of the sub-study is to:
- Evaluate safety after a fourth injection with 4 μg GAD-Alum direct into an inguinal lymph gland in 3 adult patients from the main study
- Evaluate how the above mentioned treatment influences the immune system and endogenous insulin secretion.

Intervention / Treatment
Detailed Description
Eligible patients will be treated with 4 µg GAD-Alum into an inguinal lymph gland at three occasions, with one month intervals in combination with Vitamin D (14 000 IU/week) for 4 months, starting 1 month prior to first GAD-Alum injection.
A sub-study will include three adult patients from the main study and evaluate safety after a fourth injection with 4 μg GAD-Alum into an inguinal lymph gland in combination with oral vitamin D intake. The Prolonged Extension Study Period is 12 months and will start 30,5 months after baseline.

Description
Inclusion Criteria:
- Informed consent given by patients
- Type 1 diabetes according to the ADA (American Diabetes Association) classification with < 6 months diabetes duration
- Age 12.00-29.99 years at diagnosis of Type 1 diabetes
- Fasting C-peptide ≥0.12 nmol/L
- Pos GADA(Antibodies to GAD with molecular mass 65,000) but < 50 000 random units
- Females must agree to avoid pregnancy and have a negative urine pregnancy test
- Patients of childbearing potential must agree to using adequate contraception, until 1 year after the last administration of GAD-Alum.
Exclusion Criteria:
- Previous or current treatment with immunosuppressant therapy (although topical or inhaled steroids are accepted)
- Continuous treatment with any 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
- Treatment with Vitamin D, marketed or not, or unwilling to abstain from such medication during the trial
- A history of anaemia or significantly abnormal haematology results at screening
- A history of epilepsy, head trauma or cerebro-vascular accident, or clinical features of continuous motor unit activity in proximal muscles
- Clinically significant history of acute reaction to vaccines or other drugs in the past
- Treatment with any vaccine, including influenza vaccine, within 4 months prior to planned first study drug dose or planned treatment with any vaccine up to 4 months after the last injection with study drug.
- Participation in other clinical trials with a new chemical entity within the previous 3 months
- Inability or unwillingness to comply with the provisions of this protocol
- A history of alcohol or drug abuse
- A significant illness other than diabetes within 2 weeks prior to first dosing
- Known human immunodeficiency virus (HIV) or hepatitis
- Females who are lactating or pregnant (the possibility of pregnancy must be excluded by urine βHCG (beta-human chorionic gonadotropin) on-site within 24 hours prior to the GAD-Alum treatment)
- Males or females not willing to use adequate contraception until 1 year after the last GAD-Alum treatment
- 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
