Ustekinumab Offers Potential in Protecting Beta-Cells for Adolescents with Type 1 Diabetes, Study Suggests
UK: A multicenter, double-blind, randomized phase 2 trial of Ustekinumab for adolescents with type 1 diabetes was featured in an article in Nature Medicine.
The study found that ustekinumab, a monoclonal antibody approved for psoriasis, psoriatic arthritis, and inflammatory bowel disease, seems to safely preserve pancreatic beta-cell function in children with new-onset type 1 diabetes (T1D) by targeting the interleukin (IL)-12/IL-23 pathway.
Type 1 diabetes results from the autoimmune, T-cell-mediated destruction of insulin-producing β-cells. Unlike other autoimmune diseases where immunomodulatory therapies are well-established, the primary treatment for Type 1 diabetes for over a century has been insulin replacement. However, this approach often fails to achieve optimal glycemic control, particularly in younger patients. Research has shown that even preserving a small amount of endogenous insulin production after diagnosis can significantly reduce both short- and long-term complications. This underscores the importance of targeting immune pathways involved in the Type 1 diabetes pathogenic process.
In the study conducted by Danijela Tatovic, Division of Infection and Immunity, Cardiff University School of Medicine, a report on a phase 2, multicenter, double-blind, randomized, placebo-controlled trial of ustekinumab in children and adolescents within 100 days of T1D diagnosis (the USTEKID study) was conducted.
The findings of the study highlight the crucial role of a small proinflammatory subset of TH17.1 cells in β-cell destruction and demonstrate that targeting this subset through IL-12/IL-23 inhibition helps preserve C-peptide levels.
The key findings of the study are as follows:
- A double-blind, randomized controlled trial was conducted on 72 adolescents aged 12-18 years with recent-onset T1D.
- After 12 months, β-cell function, measured by stimulated C-peptide, was 49% higher in the intervention group, meeting the prespecified primary outcome.
- The preservation of C-peptide was correlated with the reduction of T helper cells co-secreting IL-17A and interferon-γ.
- There was a notable reduction in a subset of TH17.1 cells co-expressing IL-2 and granulocyte-macrophage colony-stimulating factor.
- A significant decrease in β-cell-targeted IL-17A-secreting T cells was observed.
- These findings suggest that targeting an activated subset of TH17.1 cells in Type 1 diabetes can reduce C-peptide loss with minimal adverse effects, though confirmation in a larger study is needed.
The study concluded that ustekinumab showed a high safety profile and effectively preserved β-cells in children and adolescents with recently diagnosed Type 1 diabetes by targeting the IL-12/IL-23 pathway. This trial provides the first prospective, randomized controlled evidence of the pathogenic role of TH17 cells in Type 1 diabetes, confirming the preliminary findings from the earlier pilot study.
