Weekly insulin shot plus skin sensor could simplify diabetes care
NCT ID NCT05823948
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested a new approach for people with type 2 diabetes: a once-weekly insulin injection (insulin icodec) combined with a flash glucose monitor, a small sensor worn on the arm that tracks blood sugar continuously. The goal was to see if this combination helps control blood sugar levels over 26 weeks. The study involved 51 adults with type 2 diabetes who had never used insulin before. Participants injected insulin once a week and scanned the sensor four times daily using a study phone.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- insulin icodec (once-weekly insulin injection)
- What this could lead to
- If successful, this could make managing type 2 diabetes easier with a once-weekly insulin shot and a simple sensor to track blood sugar.
- What could go wrong
- This is a small, completed Phase 3 trial with only 51 participants. Results may not apply to everyone, and insulin can cause low blood sugar or other side effects.

Inclusion Criteria: * Informed consent obtained before any study-related activities. Study-related activities are any procedures that are carried out as part of the study, including activities to determine suitability for the study * Age above or equal to 18 years at the time of signing informed consent * Diagnosed with type 2 diabetes (T2D) greater than or equal to (\>=) 180 days before screening * HbA1c from 7.0%-11.0% (53.0-96.7 millimoles per mole \[mmol/mol\]) both inclusive at screening confirmed by central laboratory analysis * Insulin-naïve. However, short term insulin treatment for a maximum of 14 consecutive days before screening is allowed, as is prior insulin treatment for gestational diabetes * Stable daily dose(s) \>=90 days before screening of any of the following antidiabetic drug(s) or combination regimen(s) at effective or maximum tolerated dose as judged by the investigator: 1. Any metformin formulations \>= 1500 milligrams (mg) or maximum tolerated or effective dose or 2. Any metformin combination formulations \>=1500 mg or maximum tolerated or effective dose or 3. Other antidiabetic Drugs including combination products (\>=half of the maximum approved dose according to local label or maximum tolerated or effective dose) of the classes specified below: Sulfonylureas, Meglitinides (glinides), Dipeptidyl peptidase-4 (DPP-4) inhibitors, Sodium-dependent glucose cotransporter 2 (SGLT2) inhibitors, Thiazolidinedione, Alpha-glucosidase inhibitors, Oral combination products (for the allowed individual oral antidiabetic drugs, Oral or injectable glucagon-like peptide-1 (GLP-1) receptor agonists * Intensification with basal insulin is indicated to achieve fasting glycaemic target (4.4-7.2 millimoles per liter \[mmol/L\]; 80-130 milligrams per deciliter \[mg/dL\]) at the discretion of the treating investigator * Body mass index (BMI) less than or equal to (\<=) 40.0 kilograms per meter square (kg/m\^2) Exclusion Criteria: * Unwilling or unable to avoid concomitant medication e.g., ascorbic acid (vitamin C) that can influence the flash glucose monitoring (FGM) sensor throughout the study and contraindications e.g., implanted medical devices such as pacemakers * Any episodes of diabetic ketoacidosis within 90 days before screening as declared by the participant or in the medical records * Myocardial infarction, stroke, transient ischaemic attack or hospitalisation for unstable angina pectoris within 180 days before the day of screening and between screening and initiation visits * Chronic heart failure classified as being in New York Heart Association (NYHA) Class IV at screening * Anticipated initiation or change in concomitant medications (for more than 14 consecutive days) known to affect weight or glucose metabolism (e.g., treatment with orlistat, thyroid hormones, or corticosteroids) * Uncontrolled and potentially unstable diabetic retinopathy or maculopathy. Verified by a fundus examination performed within 90 days before the day of screening or in the period between screening and initiation visits. Pharmacological pupil dilation is a requirement unless using a digital fundus photography camera specified for non-dilated examination
