Trial Summary

What is the purpose of this trial?

This trial tests a new vaccine mixed with a booster substance to help patients with type 1 diabetes. The goal is to retrain their immune system to stop attacking insulin-producing cells, potentially improving their condition.

Do I need to stop my current medications for the trial?

The trial requires that you do not use medications that influence glucose tolerance or systemic immunosuppressants. If you are using non-insulin drugs to control blood sugar, you will need to stop those as well.

What data supports the effectiveness of the MAS-1 adjuvanted immunotherapy treatment for type 1 diabetes?

Research shows that MAS-1 adjuvanted immunotherapy can generate strong immune responses that help prevent diabetes in mice, with a significant number remaining diabetes-free for up to a year. Additionally, insulin B-chain immunotherapy has been effective in reducing diabetes incidence in animal models, suggesting potential benefits for type 1 diabetes. ^{1 2 3 4 5}

Is MAS-1 adjuvanted immunotherapy safe for humans?

The MAS-1 adjuvanted immunotherapy has been evaluated in a phase I clinical trial for type 1 diabetes and was found to be generally safe and well-tolerated in humans. ^{1 2 3 4 6}

How is the MAS-1 adjuvanted Insulin B-chain treatment different from other treatments for type 1 diabetes?

The MAS-1 adjuvanted Insulin B-chain treatment is unique because it uses a nanoparticular, emulsion-based adjuvant (a substance that enhances the body's immune response to an antigen) to promote Th2 and regulatory immune responses, which can provide long-term protection against type 1 diabetes. This approach focuses on modulating the immune system rather than directly affecting blood sugar levels, which is different from standard insulin therapies. ^{1 2 3 4 7}

Eligibility Criteria

This trial is for adults aged 18-45 with Type 1 Diabetes diagnosed in the last 2 years, positive for an islet cell autoantibody, and have certain levels of C-peptide. Participants must not be pregnant or planning pregnancy soon, avoid other vaccines initially, and manage diabetes intensively. Exclusions include those with significant complications or infections, drug sensitivities, or unwilling to use birth control.

Inclusion Criteria

I agree not to get routine vaccines for the first 100 days after starting the study drug, except for the COVID-19 vaccine after 60 days.

I am not pregnant and agree to prevent pregnancy during and up to 2 months after treatment.

It has been over a month since my last vaccination.

Exclusion Criteria

I have had cancer before.

I have serious diabetes complications like kidney issues or eye problems.

I am taking medication that affects my blood sugar levels.

Treatment Details

Interventions

• MAS-1 adjuvanted Insulin B-chain (Immunotherapy)

Trial Overview The study tests MAS-1 adjuvanted Insulin B-chain's safety and its ability to promote immune tolerance in Type 1 Diabetes. It's a randomized (participants are chosen by chance), double-masked (neither researchers nor participants know who gets the real treatment), placebo-controlled trial that gradually increases doses.

Participant Groups

Group I: TBD ug IBC in 0.25 mL MAS-1 emulsion Experimental Treatment 1 Intervention

7 participants to be randomized between placebo and MAS-1 adjuvanted insulin B-chain (2:5) with the optimal IBC dose selected from the first 3 groups (either 33 µg, or 109 µg, or 327 µg IBC) in 0.25 mL MAS-1 emulsion

Group II: 33 ug IBC in 0.25 mL MAS-1 emulsion Experimental Treatment 1 Intervention

7 participants to be randomized between placebo and MAS-1 adjuvanted insulin B-chain (2:5) with a 33 ug IBC dose in 0.25 mL MAS-1 emulsion

Group III: 327 ug IBC in 0.25 mL MAS-1 emulsion Experimental Treatment 1 Intervention

7 participants to be randomized between placebo and MAS-1 adjuvanted insulin B-chain (2:5) with a 327 ug IBC dose in 0.25 mL MAS-1 emulsion

Group IV: 109 ug IBC in 0.25 mL MAS-1 emulsion Experimental Treatment 1 Intervention

7 participants to be randomized between placebo and MAS-1 adjuvanted insulin B-chain (2:5) with a 109 ug IBC dose in 0.25 mL MAS-1 emulsion

Autoantigen-specific regulatory T cells induced in patients with type 1 diabetes mellitus by insulin B-chain immunotherapy. Orban, T., Farkas, K., Jalahej, H., et al.[2021]

Intermittent immunizations with insulin's B-chain in nonobese diabetic (NOD) mice effectively prevent diabetes, suggesting a potential therapeutic approach for autoimmune diabetes.

The mechanism involves inducing a protective immune response that alters the nature of insulitis lesions, reducing harmful inflammation and promoting a more protective state, although it does not decrease the overall inflammation present.
