B. infantis: Activated B. infantis EVC001; Bifidobacterium longum subsp. infantis; 8 x 109 colony forming units (CFU) per day
Placebo: Lactose identical in appearance and taste to the active supplement
Study summary
Investigator initiated, randomised, placebo-controlled, double-blind, multi-centre primary intervention study to assess whether daily administration of B. infantis EVC001 from age 7 days to 6 weeks (+14 days) until age 12 months (+ 14 days) to children with elevated genetic risk for type 1 diabetes reduces the cumulative incidence of beta-cell autoantibodies in childhood.

Inclusion Criteria:
1. Infants between the ages of 7 days and 6 weeks (+14 days in case of illness or COVID-19 related issues or unexpected delay in result reporting) at the time of randomisation.
2. A 10% or higher genetic risk to develop multiple beta-cell autoantibodies by age 6 years:
1. For infants without a first-degree family history of type 1 diabetes, high genetic risk is defined as a DR3/DR4-DQ8 or DR4-DQ8/DR4-DQ8 genotype and a genetic risk score that is in the upper 25th centile (\>14.4) or a DR3/DR4-DQ8 genotype with a GRS between the upper 50th (14.0) and 25th centile and a GG genotype at the rs3763305 SNP. These represent around 1% of all newborns.
2. For infants with a first-degree family history of type 1 diabetes, high genetic risk is defined as having HLA DR4 and DQ8, and none of the following protective alleles: DRB1\*1501, DQB1\*0503, DRB1\*1303. These represent around 30% of infants with a first-degree family history of T1D.
3. Written informed consent signed by the custodial parent(s).-
Exclusion Criteria:
1. Any medical condition, concomitant disease or treatment that may interfere with the assessments or may jeopardize the participant's safe participation in the study, as judged by the Investigators.
2. Preterm delivery \< 36 weeks of gestation.
3. Proven immunodeficiency.
4. Any condition that could be associated with poor compliance.5. Diagnosis of diabetes at the time of recruitment
Primary outcome measure(s)
Persistent confirmed multiple beta-cell autoantibodies — Through study completion, up to 6.5 years Persistent confirmed multiple beta-cell autoantibodies is defined as confirmed IAA, confirmed GADA, confirmed IA-2A, or confirmed ZnT8A in two consecutive samples, AND a confirmed second antibody from these four antibodies in one sample.
The primary outcome is the elapsed time from the random treatment assignment to the first confirmed autoantibody positive sample used in defining the persistent confirmed multiple beta-cell autoantibody positive status. Diabetes in the absence of multiple beta-cell autoantibodies is also considered as a primary outcome endpoint, and in this case, the date of diagnosis is the time of the end point.
