Plain-language summary

This study is being done to look at the effect and safety of different doses of NNC0662-0419 in people living with type 2 diabetes when compared to placebo or semaglutide. The purpose of this clinical study is to find out if NNC0662-0419 is effective and safe for treating people living with type 2 diabetes. Participants will get either NNC0662-0419, semaglutide or placebo. Which treatment participants get is decided by chance. NNC0662-0419 is a new medicine which cannot be prescribed by doctors but has previously been tested in humans. Semaglutide is an approved medication to treat type 2 diabetes.

Inclusion criteria * Male or female (sex at birth). * Age 18-75 years (both inclusive) at the time of signing the informed consent. * Glycated haemoglobin (HbA1c) of 7.0-10.0 percent (%) (53-86 millimoles per mole \[mmol/mol\]) (both inclusive) as assessed by central laboratory at screening. * Willingness to obtain a high weight loss (greater than \[\>\] 25% of weight at baseline). Exclusion criteria * Treatment with any medication for the indication of diabetes or obesity other than stated in the inclusion criteria within 90 days before screening. However, short term insulin treatment for a maximum of 14 consecutive days and prior insulin treatment for gestational diabetes are allowed. * Uncontrolled and potentially unstable diabetic retinopathy or maculopathy. Pharmacological pupil-dilation is a requirement unless using a digital fundus photography camera specified for non-dilated examination. * Known hypoglycaemic unawareness as indicated by the investigator according to Clarke's Questionnaire.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
