A Study to evaluate the safety and feasibility of Diamyd® in individuals at risk for Type 1 diabetes
EU CTIS ID: 2024-513350-30-00
What this study is testing
The primary objective is to evaluate the feasibility and safety of two and three intralymphatic injections of Diamyd (one month apart) in individuals aged 8 - <18 years with HLA haplotype DR3-DQ2 and multiple islet autoantibodies (Stage 1 or Stage 2) at increased risk for T1D.
- Therapeutic exploratory (Phase II)

Who can take part
You may be able to join if
- Written informed consent/assent from the individual and the individual's parents or caretaker(s)
- Males and females aged ≥8 and <18 years old at the time of Screening.
- Possess the HLA DR3-DQ2 haplotype.
- Seropositive for GADA and at least one additional T1D-associated autoantibody (IA-2A, ZnT8A or IAA).
You likely can't join if
- Diagnosis of T1D (stage 3 T1D, according to the American Diabetes Association [ADA] classification).
- Treatment with any (live or inactive) vaccine, including influenza vaccine and Coronavirus Disease 2019 (COVID-19) vaccine, within 4 weeks prior to planned first dose of study drug; or planned treatment with any vaccine up to 4 weeks after the last injection with study drug.
- Ongoing diagnosed post-COVID19 syndrome.
- Known diagnosis of human immunodeficiency virus (HIV), hepatitis B or hepatitis C infection. Individuals with previous hepatitis C infection that is now cured may be eligible.
- Any clinically significant concomitant medical condition, including but not limited to other autoimmune diseases, cardiovascular, gastrointestinal, hematological, immune, renal including a history of renal transplantation or neurological that in the opinion of the investigator would interfere with trial participation or procedures. Celiac disease with adequate diet as well as stable autoimmune thyroiditis will be permitted.
- Any clinically significant abnormal findings detected during Screening that might jeopardize the individual's safety or ability to complete the trial.
