As the first oral GLP-1 receptor agonist (GLP-1RA), oral semaglutide (sema) may facilitate increased access to the benefits of GLP-1RA therapy in broader care settings. Understanding the management of GLP-1RA therapy when intolerability occurs, including gastrointestinal (GI) adverse events (AEs), is important to overcome potential barriers to treatment persistence. The PIONEER 6 trial (NCT02692716; N=3183) examined the efficacy and safety of oral sema in patients (pts) with T2D either ≥50 years with established cardiovascular (CV) or kidney disease, or ≥60 years with CV risk factors. In total, 27% of pts stopped taking oral sema at least once during the trial due to an AE, but only 12% permanently discontinued due to an AE. We thus evaluated medication management strategies within PIONEER 6 to assess their role in supporting treatment continuation. Pts on oral sema underwent dose escalation starting at 3 mg, increasing to 7 mg after 4 weeks, and 14 mg after 8 weeks. Investigators were permitted to reduce the dose if AEs developed and to re-escalate the dose once symptoms had resolved or diminished. Pts were educated as needed to address GI tolerability issues throughout the trial. Pts who discontinued treatment because of an AE were encouraged to resume treatment once willing or once the AE had ceased. The time off oral sema was considered a treatment pause. If treatment pauses were >21 days, re-escalation from a lower dose was recommended to mitigate GI AEs. Discontinuation of oral sema (temporary and permanent) mostly occurred during the initial dose escalation period. In total, 23% of pts receiving oral sema had ≥1 treatment pause, the majority of whom (72%) had just one pause. The median duration of treatment pause was 21 (IQR 7-51) days. Importantly, 75% of pts restarted oral sema after the first AE-related treatment discontinuation. These data highlight the role of treatment pauses, flexibility, and education in mitigating potential AEs to support treatment persistence on GLP-1RAs. Disclosure V. R.

Glucagon-like peptide-1 receptor agonists (GLP-1RA) and SGLT2 inhibitors (SGLTi) are widely used to treat type 2 diabetes (T2D) but trial data on their combined use are limited. We report the first data on oral semaglutide in combination with SGLT2i. This was a post-hoc subgroup analysis of the 52-week, double-blind, double-dummy PIONEER 4 trial (NCT02863419), in which patients with T2D uncontrolled on metformin with or without SGLT2i were randomized 2:2:1 to once-daily oral semaglutide 14 mg, subcutaneous (s.c.) liraglutide 1.8 mg or placebo. Glycated hemoglobin (HbA1c) and body weight (BW) data presented are for the trial product estimand (on-trial product without rescue medication). In total, 183 (26%) of 711 patients were receiving SGLT2i treatment at baseline which continued throughout the trial. Subgroups of patients receiving SGLT2i had a lower percentage of females, slightly longer mean T2D duration and higher BW. Changes in HbA1c and BW were similar in patients receiving oral semaglutide or s.c. liraglutide with or without SGLT2i. Occurrence of most gastrointestinal adverse events was similar in patients on GLP-1RA with and without SGLT2i. In conclusion, improvements in HbA1c and BW after one year as well as safety profile were similar in patients on GLP-1RA with or without background SGLT2i. Disclosure R.E.
