GPPAD-POInT (Global Platform of Autoimmune Diabetes - Primary Oral Insulin Trial)

October 4, 2024 updated by: Technical University of Munich

Oral Insulin Therapy for Prevention of Autoimmune Diabetes

The GPPAD-POInT Study is designed as a randomized, placebo-controlled, double blind, multicentre, multinational primary prevention phase IIb study aiming to induce immune tolerance to beta-cell autoantigens through regular exposure to oral insulin for a period of 29 to 32 months. The hypothesis is that regular exposure to oral insulin throughout the period in life where beta-cell autoimmunity usually initiates will tolerize against insulin and train the body's immune system to recognize the treatment product without reacting adversely to it in a manner seen in children who develop T1D. This immune tolerance induction therapy would reduce the likelihood of beta-cell autoimmunity. The study objective is to determine whether daily administration of oral insulin from age 4 months - 7 months until age 3.00 years to children with elevated genetic risk for type 1 diabetes reduces the cumulative incidence of beta-cell autoantibodies and diabetes in childhood.

Detailed Description

The GPPAD-POInT-Study aims to determine whether daily administration of oral insulin to children from age 4 months - 7 months with elevated genetic risk for type 1 diabetes reduces the cumulative incidence of beta-cell autoantibodies and diabetes in childhood. The purpose of the GPPAD-POInT-Study is to induce immune tolerance to beta-cell autoantigens through regular exposure to oral insulin for a period of 29 to 32 months. Together with the results of the Pre-POINT-Early Study, this phase IIb study aims to investigate and consolidate the findings from the pilot Pre-POINT Study, namely safety and immune efficacy at a daily dose of 67.5 mg oral insulin. Since babies and young children will be tested in the GPPAD-POInT-Study, the 67.5 mg dose will be reached by dose escalation starting at 7.5 mg for 2 months, followed by exposure to 22.5 mg for 2 months, and reaching the desired 67.5 mg dose. The GPPAD-POInT-Study aims to recruit 1040 children into the trial.

The active substance for oral application is human insulin. Oral Insulin will be applied as a capsule containing 7.5, 22.5 and 67.5 mg of the active substance together with filling substance microcrystalline cellulose.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

Accepts Healthy Volunteers

Yes

Inclusion Criteria:

1. Infant between the ages of 4 months and 7 months at the time of randomization.
