About

A prospective, randomised, open-labelled, multi-center study. The aim of the Steno 1 study is to test multifactorial intervention in individuals with type 1 diabetes at high risk of CVD with ambitious treatment targets. We will include 2000 participants. Follow-up is 5 years.

Full description

Background: Individuals with type 1 diabetes (T1D) are at high risk for cardiovascular disease (CVD). Even with optimal glycemic control, the risk is doubled compared to healthy individuals. Treatment of type 2 diabetes (T2D) is based on multifactorial intervention (MFI). The development of new drug classes has had profound impact on treatment guidelines through a documented reduction in mortality and morbidity in individuals with T2D. MFI acknowledges the need for control and interventions directed towards several risk factors for CVD, and not focus merely on glucose levels. A fundamental change in risk management with a strong focus on MFIs to lower CVD risk in individuals with T1D and comorbidity of CVD, CKD, HF or obesity, has the potential to improve morbidity and survival in T1D.

Objective: The aim of the Steno 1 study is to test MFI in individuals with T1D at high risk of CVD with ambitious treatment targets. We hypothesize, that the MFI reduces major adverse cardiovascular endpoints (MACE) hospitalization for heart failure (HHF), kidney failure and mortality.

Design: This study uses a PROBE design (prospective, cluster-randomized, open, blinded endpoint evaluation), as it will not be possible to mask the MFI. The study is a superiority trial.

Patient population: High-risk individuals with T1D of >10 years duration (>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). Participants are recruited from Steno Diabetes Centres or partner clinics.

Randomization: There will be formed three clusters (large patient pool, intermediate- and small). Within each cluster, participating centers will be randomised to either group A or group B. Group A will receive current guideline-recommended standard of care and group B will receive the multifactorial risk based intensive therapy. Participants are allocated to centers based on geography and not based on phenotype.

Intervention: For the intensively treated group, the MFI will be determined by the risk profile and risk markers of each individual and the participants will be allocated to Semaglutide, sotagliflozin, finerenone, ezetimibe and/ or PCSK9-inhibitors. The intervention will also comprise more ambitious treatment targets for blood pressure and lipid levels. In addition, all participants will take aspirin 75 mg OD.

Endpoints: The primary endpoint is to determine whether MFI is superior to standard care with respect to MACE+HHF (composite of time to first non-fatal myocardial infarction, first non-fatal stroke, cardiovascular death or first hospitalization for heart failure). Secondary endpoints are to determine whether MFI is superior to standard care with respect to all-cause mortality, a composite endpoint of renal function (end-stage kidney disease (ESKD) (dialysis, renal death, transplantation) or >50% sustained decline in eGFR) compared to standard of care and to determine whether MFI including the use of SGLT2i and GLP1RA leads to an increased frequency of diabetic ketoacidosis compared to standard of care.

Enrollment: 2,000 estimated patients

Sex: All

Ages: 40 to 90 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

1. Given written informed consent
2. Male or female patients ≥40 years old with type 1 diabetes (diagnosis before age 30 with insulin from onset or if diagnosis after 30 years of age insulin from onset and DKA or positive autoantibodies ( in accordance with local guidelines)) during >10 years.
3. Presence of chronic kidney disease (UACR >30 mg/g or eGFR < 60 ml/min/1.73 m2) OR history of ischemic heart disease (previous myocardial infarction, stroke or angina) OR history of heart failure OR obesity grade 2 and 3 (BMI>35 kg/m2) OR 10-year CVD risk >10% according to Steno Type 1 Risk Engine.
4. Fertile females must use highly efficient chemical, hormonal and mechanical contraceptives during the whole study and at least 2 months after cessation of study drug. The following contraceptive methods are approved: IUD or hormonal contraception that inhibits ovulation, i.e. pills, implantations, transdermal patches, vaginal ring or depot injection. Alternatively, be in menopause (i.e. must not have had regular menstrual bleeding for at least one year), have undergone bilateral oophorectomy or have been surgically sterilized or hysterectomised at least 12 months prior to screening. Fertile participants will be pregnancy tested every six months with urine HCG.
5. Ability to communicate with the investigator and understand informed consent.

Exclusion criteria

1. Type 2 diabetes, MODY, secondary diabetes.
2. History of pancreatitis.
3. Body mass index < 18.5 kg/m2
4. Females of childbearing potential who are pregnant, breast-feeding, intend to become pregnant or are not using adequate contraceptive methods.
5. Known or suspected abuse of alcohol or recreational drugs.
6. Participant in another intervention study.
7. CKD stage 5.

Trial design

Primary purpose: Treatment

Allocation: Randomized

Interventional model: Parallel Assignment

Masking: None (Open label)

---

2,000 participants in 2 patient groups

Multifactorial intervention group

Active Comparator group

Description:

The multifactorial intervention will be determined by the risk profile and risk markers of each individual and the participants will be allocated to Semaglutide, sotagliflozin or finerenone. The intervention will also comprise more ambitious treatment targets for blood pressure and lipid levels. In addition, all participants will take aspirin 75 mg OD.

Treatment:

Drug: Sotagliflozin

Drug: Semaglutide

Drug: Finerenone

Drug: Aspirin tablet

Standard intervention group

No Intervention group

Description:

During the whole study period the standard intervention shall be done according to current Danish and international (ADA/EASD) guidelines. This will address similar risk factors as in the intensive group, but to a less ambitious treatment target for blood pressure and lipid lowering and will not include the use of SGTL2i, finerenone or GLP-1RA, unless these drug classes become recommended in future versions of guidelines.
