Oral Semaglutide and Cardiovascular Outcomes in People With Type 2 Diabetes, According to SGLT2i Use: Prespecified Analyses of the SOUL Randomized Trial

CirculationPublished Secondary analysis of the SOUL randomised trial

Authors' conclusion

Oral semaglutide reduced major adverse cardiovascular event outcomes independently of concomitant SGLT2i treatment, and this combination appeared to be safe.

Study context

Population
T2DM with atherosclerotic CVD and/or CKD, analysed by baseline SGLT2i use (yes n=2596; no n=7054) and any in-trial SGLT2i use (yes n=4718; no n=4932)
Participants
9,650 participants
Comparison
Oral semaglutide vs placebo, by SGLT2i use
Primary endpoint

  • CV death
  • Nonfatal MI
  • Nonfatal stroke
Follow-up
Mean 47.5±10.9 months
Methodological detailsprespecified subgroup analysis, placebo-controlled
