Recruiting now · Phase 1

Conditions studied: Type 2 Diabetes

In brief

In this study, the investigational product will be compared with insulin degludec (Tresiba®) and insulin icodec (Awiqli®). The comparator products are approved for the treatment of T2DM in the European Union.

Who can join

Age: 18 and older, up to 70. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Signed and dated informed consent obtained before any trial-related activities. Trial-related activities are any procedures that would not have been done during normal management of the participant. 2. Male or female person with type 2 diabetes mellitus. 3. Age between 18 and 70 years, both inclusive. 4. Body Mass Index (BMI) between 27.0 and 38.0 kg/m\^2, both inclusive. 5. Diabetes duration of at least 12 months. 6. Stable basal insulin regimen for at least 3 months. 7. Total daily basal insulin dose between 0.2-0.7 (I)U/kg/day, both inclusive. 8. HbA1c <= 9.0%. 9. Have venous access sufficient to allow cannulation for blood sampling as required by the protocol.

You may not qualify if…

• Known or suspected hypersensitivity to IMPs or any of the excipients or to any component of the IMP formulations. 2. Previous participation in this trial. Participation is defined as randomized at Visit 2.
• Receipt of any medicinal product in clinical development within 30 days or at least 5 half-lives of the related substances and their metabolites (whichever is longer) before randomization in this trial. 4. Use of insulin icodec as basal insulin. 5. History of multiple and/or severe allergies to drugs or foods or a history of severe anaphylactic reaction. 6. Any history or presence of cancer except basal cell skin cancer or squamous cell skin cancer as judged by the investigator during the last 5 years prior to screening. 7. Clinically relevant comorbidity, capable of constituting a risk for the participant when participating in the trial or of interfering with the interpretation of data. Signs of acute illness as judged by the investigator. 9. Any serious systemic infectious disease during four weeks before randomization in this trial, as judged by the investigator. 10. Clinically significant abnormal values for hematology, biochemistry, coagulation, or urinalysis as judged by the investigator. 11. Estimated glomerular filtration rate (eGFR) < 60.0 mL/min/1.73m2. 12. Systolic blood pressure < 90 mmHg or >159 mmHg and/or diastolic blood pressure < 50 mmHg or > 99 mmHg at screening (one repeat test will be acceptable in case of suspected white-coat hypertension). 13. Heart rate at rest (as measured in vital sign assessment at screening) outside the range of 50-90 beats per minute at screening. This exclusion criterion also applies to participants who are on anti-hypertensives. 14. Clinically significant abnormal standard 12-lead electrocardiogram (ECG) after 5 minutes resting in a supine position at screening, as judged by the investigator. 15. Proliferative retinopathy or maculopathy as judged by the investigator based on a recent (<1.5 years) ophthalmologic examination. 16. Severe neuropathy, in particular autonomic neuropathy, as judged by the investigator.
• Recurrent severe hypoglycemia (more than 1 severe hypoglycemic episode requiring assistance from another person within 180 days before screening). 18. Hypoglycemic unawareness as judged by the investigator. 19. Hospitalization for diabetic ketoacidosis during the previous 6 months. 20. Use of oral antidiabetic drugs (OADs) within 1 month or 5 half-times (whichever is longer) prior to screening with the exception of stable doses (for at least 3 months prior to screening) of metformin, DPP4, SGLT2 inhibitors and GLP-1 receptor agonists. 21. Increased risk of thrombosis, e.g. participants with a history of deep leg vein thrombosis or family history of deep leg vein thrombosis, as judged by the investigator. 22. Significant history of alcoholism or drug abuse as judged by the investigator or consuming more than 24.0 grams alcohol/day (for males), 12.0 grams alcohol/day (for females) on average. 23. A positive result in the alcohol and/or urine drug screen at the screening visit.
• Smoking more than 5 cigarettes or the equivalent per day. 25. Inability or unwillingness to refrain from smoking and use of nicotine substitute products during the inpatient period Tested positive for hepatitis Bs antigen. 27. Tested positive for hepatitis C antibodies. (Presence of hepatitis C antibodies will not lead to exclusion if liver function tests are normal, and a hepatitis C polymerase chain reaction is negative). 28. Positive result to the test for HIV-1/2 antibodies or HIV-1 antigen. 29. Current treatment with systemically effective corticosteroids, monoamine oxidase inhibitors, systemic non-selective beta-blockers, growth hormone, non-routine vitamins or herbal products. 30. Use of non-prescription medication, including herbal products and non-routine vitamins, within 2 weeks prior screening that will interfere with PK of GZR4, insulin degludec or insulin icodec, as judged by the investigator. 31. Blood donation or blood loss of more than 500 mL within the last 3 months before screening.
• Mental incapacity, unwillingness or language barriers precluding adequate understanding or co-operation. 33. Committed to an institution by virtue of an order issued either by the judicial or the administrative authorities. 34. If female, pregnancy or breast-feeding. 35. Women of childbearing potential who are not using a highly effective contraceptive method.
• Men with non-pregnant partner(s) of childbearing potential not willing to use male contraception (condom) in addition to a highly effective contraceptive method during trial participation. 37. The investigator considers a person as unsuitable for inclusion in the trial for any other reason.
