Comparing GZR4 versus insulin icodec for adults with type 2 diabetes on basal insulin

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This Phase IIIb interventional trial randomizes adults with type 2 diabetes who are treated with basal insulin to receive either GZR4 or insulin icodec, with or without background non‑insulin antidiabetic medications. The study will track blood sugar control, adverse events, and patient‑reported outcomes over the treatment period. Investigators will compare efficacy and safety between the two treatment arms and collect data on tolerability and patient experience. Results will inform whether GZR4 offers comparable or improved outcomes relative to insulin icodec in this population.

* Subjects who are pregnant, lactating or planning to become pregnant during the study at screening.
