About this study

The study GPPAD-05 AVAnT1A is a phase 4 clinical trial intending to enroll 2252 children, who will be randomly assigned to receive COVID-19 vaccination (Comirnaty® 3 μg Omicron XBB.1.5 or new variant Comirnaty vaccines ) or placebo from age 6 months. The study is an investigator initiated, randomized, controlled, multicentre, multinational, primary prevention trial for children at increased risk of type 1 diabetes. The primary objective is to determine whether vaccination of children with elevated genetic risk for type 1 diabetes against COVID-19 from 6 months of age reduces the cumulative incidence of islet autoantibodies or type 1 diabetes in childhood. Secondary objectives are: 1. to determine whether vaccination against COVID-19 similarly reduces the cumulative incidence of multiple islet autoantibodies in childhood. 2. to determine whether vaccination against COVID-19 similarly reduces the cumulative incidence of type 1 diabetes in childhood and 3. to determine whether vaccination against COVID-19 similarly reduces the cumulative incidence of celiac disease-associated transglutaminase autoantibodies in childhood. Further exploratory objectives are described in the study protocol. Study participants will be identified through an ongoing study screening for genetic risk of type 1 diabetes using a polygenic risk score (NCT03316261). Eligible participants will be enrolled at age 3.00 to 4.00 months (baseline visit). Randomization to vaccine or placebo will occur at a…
