The GPPAD-04 SINT1A study will evaluate whether early, regular supplementation with a daily dose of a probiotic can reduce the risk of developing beta-cell autoimmunity in children identified by GPPAD-02 as being genetically predisposed to developing type 1 diabetes. Children will be enrolled at age 7 days to 6 weeks (+14 days) and the study product (B. infantis EVC001 or Placebo) will be administered orally once per day from enrollment until age 12 months (+14 days). The hypotheses is that administration of B. infantis may have a positive influence on the intestinal flora and thus have a regulating effect on the immune system. The study is designed to investigate whether pathogenic immune reactions as in type 1 diabetes but also in other diseases, such as celiac disease, can be reduced and if the disease can be prevented. Children will be followed until age 3.5 - 6.5 years (2.5 - 5.5 years after end of treatment). Throughout the study data will be collected by regular study visits, phone calls with the families and electronic questionaires. Blood samples will be collected to investigate glucose, HbA1c, beta-cell autoantibodies, transglutaminase antibodies, vaccine responses, genetic susceptibility and mechanistic markers. Stool samples will be collected for further assessments such as colonization,microbiome, pH and calprotectin. Exploratory outcomes (allergy, vaccine responses, stool microbiome, blood metabolomics, stool pH and calprotectin or site specific ancillary measurements) may be assessed or in part assessed on a portion of the participants after unblinding the study. They may not necessarily be included in the primary outcome analysis and publication.
