Research

Studies & key findings

  • The REWIND cardiovascular outcomes trial (Lancet 2019, n=9,901, median follow-up 5.4 years) showed once-weekly dulaglutide reduced the primary MACE composite endpoint by 12% (HR 0.88, p=0.026) in T2D patients, including a notably large proportion with no prior cardiovascular disease — supporting cardioprotection even in lower-risk populations.
  • The AWARD clinical development program (six Phase 3 trials) established dulaglutide 1.5 mg as superior to exenatide, insulin glargine, metformin, and sitagliptin comparators on HbA1c reduction, with AWARD-1 demonstrating -1.51% HbA1c vs -0.99% for exenatide at 52 weeks.
