Cardiovascular disease (CVD) risk remains high but unevenly distributed in patients with type 2 diabetes mellitus (T2DM). Current risk stratification strategies are far from optimal, leading to both undertreatment and overtreatment of patients. The STENO INTEN-CT trial aims to evaluate a strategy of improved CVD risk management by using cardiac CT (coronary artery calcification (CAC)) for stratification and tailoring of multifactorial cardiovascular treatment based on CAC score. We hypothesise that (1) intensified medical treatment will lower CVD event rates in high-risk patients (CAC≥100), and (2) less intensive multifactorial treatment is safe in very low-risk patients (CAC=0).

The Steno INTEN-CT trial is an investigator-initiated, pragmatic, open-label, event-driven randomised controlled trial including patients with T2DM without known CVD. All participants (expected n=7300) will be invited for a non-contrast coronary CT scan. After the scan, participants will be randomised to either standard treatment (blinded for CAC results) or CAC-based treatment. Participants in CAC-based treatment and their general practitioner (GP) will receive information on CAC and a recommendation of multifactorial treatment. High-risk participants in the interventional arm will be invited for one or more initial study visits to intensify treatment with a combination of sodium glucose co-transporter 2 inhibitors, glucagon-like peptide 1 receptor agonists, high-dose lipid-lowering, antihypertensive and antithrombotic treatment. Very low-risk patients in the interventional arm will be recommended less intensive treatment targets. After initial study-related activities, all participants will continue to be taken care of by their GP guided by specific treatment recommendations. The primary outcome in the primary hierarchical analysis (the rate of the combined CVD endpoint of cardiovascular death, non-fatal myocardial infarction, non-fatal stroke and hospitalisation for heart failure) will be monitored through national health registries. The trial is event-driven, but a median follow-up of 5 years is expected. Key secondary outcomes include patient-reported outcomes, quality-adjusted life years and healthcare costs.

The protocol V.1.9 is approved by the Research Ethics Committee and the Danish Medicines Agency and the Danish Data Protection Agency. The results of the study—positive, negative or neutral—will be published in peer-reviewed journals and through www.clinicaltrials.org.

Total diet replacements (TDRs) and weight loss medications (WLMs) have proven effective in producing substantial weight loss for individuals with obesity. Evidence is lacking on whether combining these treatments is effective and cost-effective in primary care for adults with obesity class I (body mass index (BMI) 30–34.9) or uncomplicated obesity class II or higher (BMI≥35 without obesity-related disease).

LightCARE is a 2-year 1:1 randomised, parallel-group, clinical superiority trial with blinded outcome assessment evaluating the benefits and harms of an intensive weight loss (IWL) intervention compared with usual care for adults with obesity in Denmark and the UK. The trial will include 400 participants aged 18–60 years with obesity class I or uncomplicated obesity class II or higher. The IWL programme aims to achieve and maintain a weight loss of ≥20% through a flexible and individualised combination of TDR, behavioural support, including physical activity and sleep guidance, and WLM if needed and will continue for 2 years. The control group will receive usual care offered in each country, typically consisting of brief behavioural support for weight loss. The primary outcome is body weight 2 years after randomisation. Secondary outcomes will include the proportion of participants achieving ≥20% weight loss, Short-Form-36 Mental Component Score, 4-m gait speed and Metabolic Syndrome Severity-Z score. Serious adverse events, the incidence of eating disorders and bone mineral density will be evaluated as safety outcomes. We will also examine the cost-effectiveness of the intervention, within the trial and in the longer term through modelling. We will conduct a process evaluation to inform any future implementation.

Ethical approval was granted in Denmark (December 2023, H-23051332) and the UK (August 2024, 24/SC/0210). Findings from the trial will be disseminated through peer-reviewed journals and scientific conferences.
