• For the efficacy estimand, efsitora reduced A1C by 1.31% compared to 1.27% for insulin glargine, resulting in an A1C of 6.92% and 6.96%, respectively.
• For the treatment-regimen estimand, efsitora reduced A1C by 1.19% compared to 1.16% for insulin glargine, resulting in an A1C of 7.05% and 7.08%, respectively.

Additionally, participants taking efsitora or insulin degludec spent approximately two hours more time in range (glucose 70-180 mg/dL) per day for weeks 22-26 compared to baseline.
