The Steno 1 study: Multifactorial intervention to reduce cardiovascular disease in type 1 diabetes-rationale and protocol of the prospective, randomized, open-labelled multicentre study
Abstract
Aims: Individuals with type 1 diabetes are at high risk of cardiovascular disease (CVD) and chronic kidney disease (CKD) even with optimal glycaemic control. The Steno 1 study will test a strategy of intensified care based on multifactorial intervention (MFI) including treatment with semaglutide, sotagliflozin and finerenone in high-risk individuals with type 1 diabetes. We hypothesize that this strategy will reduce major adverse cardiovascular endpoints (MACE), hospitalization for heart failure (HHF), progression of CKD and mortality.
Materials and methods: The study is a prospective, cluster-randomized, open study with blinded endpoint evaluation. We will enrol 2000 high-risk individuals with type 1 diabetes of >10 years duration. All five Steno Diabetes Centres and 11 partner hospitals in Denmark will participate, with the addition of the Steno Diabetes Centres in Greenland and the Faroe Islands. Sites will be randomized either to receive guideline-recommended standard-of-care, or to receive the MFI. Eligible individuals with type 1 diabetes (≥40 years of age with presence of either CKD, CVD, HF, obesity or a >10% 5-year CVD risk determined by the Steno T1 Risk Engine) will be included. For the MFI group, the intervention will comprise more ambitious treatment targets for blood pressure and lipid levels, and in addition, participants will be allocated to semaglutide, sotagliflozin and/or finerenone based on phenotype.
Results and conclusions: The Steno 1 study will…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design.
