GZR33 vs insulin degludec
Same mechanism, same race: design-graded trial evidence for both assets, with the grading rationale shown. Grades describe the quality of the evidence, never the merits of either security.

The trial was randomized and actively controlled, with 1,030 participants, but it was not blinded and its primary endpoint was the surrogate measure of change in HbA1c rather than a hard clinical outcome. HbA1c changed by -1.06% with insulin degludec versus -1.19% with insulin glargine, but no statistical comparison is reported, so whether the primary endpoint was met is unclear.
