803-P: Superior Glycemic Control with Once-Weekly Insulin Icodec with a Dosing Guide App vs. Once-Daily (OD) Basal Insulin Analogs in Insulin-Naïve T2D—ONWARDS 5

ONWARDS 5 (NCT04760626), a 52-week, open-label, randomized, phase 3a trial with real-world elements, assessed effectiveness and safety of once-weekly insulin icodec with a dosing guide app (icodec) vs OD basal insulin analogs (degludec, glargine U100 or glargine U300) in insulin-naïve adults with T2D. Participants (mean: 59.3 yrs; 32.8 kg/m2) were randomized 1:1 to icodec or OD analogs. The dose guidance app aided icodec titration; OD analogs were titrated as per standard of care. Estimated mean A1C change from baseline (BL) to week 52 was greater with icodec (-1.68%-points, BL 9.0%) vs OD analogs (-1.31%-points, BL 8.9%) confirming non-inferiority (p<0.0001) and superiority (p=0.009) of icodec vs OD analogs. Patient-reported outcomes (DTSQ and TRIM-D) were statistically significant in favor of icodec vs OD analogs at week 52. Rates of level 2 (<54 mg/dL) or level 3 (severe) hypoglycemia were low for both treatments (0.19 [icodec] vs 0.14 [OD analogs] events per person-year of exposure). There were no significant differences between treatments in time to treatment discontinuation/intensification. Overall, icodec with a dosing guide app showed superiority in A1C reduction, and significant improvement in treatment satisfaction and compliance scores vs OD analogs, with low hypoglycemia rates, in insulin-naïve adults with T2D in a real-world setting.
