Patients (pts) with T2D uncontrolled on insulin ± metformin were randomized to oral semaglutide (sema) 3 mg (N=184), 7 mg (N=182) or 14 mg (N=181), or placebo (pbo; N=184) in a 52-week (week) double-blind trial (NCT03021187). Total daily insulin dose was reduced by an optional 20% and capped at baseline (BL) level for week 0-26 and freely adjustable for week 26-52. Endpoints were change from BL to week 26 in HbA1c (primary) and body weight (BW; confirmatory secondary). Two scientific questions were addressed by defining two estimands: a treatment policy estimand (regardless of trial product discontinuation or rescue medication use), and a trial product estimand (on trial product without rescue medication use) in all randomized pts. Oral sema was superior to pbo in reducing HbA1c and BW at week 26 (treatment policy estimand). Significantly greater, dose-dependent HbA1c and BW reductions vs. pbo were achieved at week 26 and 52 (both estimands; Table). Total daily insulin dose was significantly reduced from BL with oral sema vs. pbo at week 26 (except 3 mg) and 52. The rate of hypoglycemia was not significantly different vs. pbo (Table). Most frequent AE with oral sema was nausea (11.4-23.2% of pts vs. 7.1% with pbo) and 7.1-13.3% of pts prematurely discontinued due to AEs (vs. 2.7% with pbo). As add-on to insulin ± metformin, oral sema had superior HbA1c and BW reductions vs. pbo at week 26. It also reduced insulin use by week 52 and was well tolerated without significantly increasing hypoglycemia rate.
