E.2 Objective of the trial |
E.2.1 | Main objective of the trial |

E.3 | Principal inclusion criteria |
1. Written informed consent signed by either both parents or legal guardian(s). 2. Children aged 1 year to 7 years (randomization must be performed prior to 8th birthday) who: a. have the HLA DR3-DQB1*0201/DR4-DQB1*0302 or HLA DR3-DQB1*0201/DR4-DQB1*0304 genotype or b. have a first degree relative with type 1 diabetes, and have a HLA genotype that includes a HLA DR4-DQB1*0302 or HLA DR4-DQB1*0304 haplotype, and does not include one of the following alleles: DR11, DR12, DQB1*0602, or haplotypes: DR7-DQB1*0303, DR14-DQB1*0503, DR13-DQB1*0603 and 3. are islet autoantibody negative (autoantibodies against insulin, GAD, IA-2 and ZnT8) at the time of screening (time between screening sample collection and randomization must not exceed 90 days).
|
|
E.4 | Principal exclusion criteria |
Participants meeting any of the following criteria will NOT be eligible for inclusion into the study: 1. Concomitant disease or treatment that may interfere with assessment or cause immunosuppression, as judged by the investigators. 2. Any condition that could be associated with poor compliance. 3. Any defect or pathology of nasal passage that would preclude application of the intranasal spray. 4. Any moderate to severe intolerance to ingredients of the investigational medicinal product.

Definition of the end of the trial and justification where it is not the last
visit of the last subject undergoing the trial
|
End of trial will be the time when all mechanistic assays have been completed all lab results are available. Mechanistic assays can only start after LPLV and measurement of all study related lab values including T-cell-stimulation tests is very complex and time-consuming. It's expected that it will take several months until these data are available and can be entered into the database. |
