Trulicity® (dulaglutid): Kardiovaskulära resultat jämfört med andra GLP-1 receptoragonister

Då REWIND-studien inte omfattade aktiva jämförelsepersoner finns inga data tillgängliga för jämförelse med andra GLP-1-receptoragonister vad gäller kardiovaskulära resultat.

Detailed Information

The Researching CV Events with a Weekly INcretin in Diabetes (REWIND) study was an event-driven, randomized, double-blind, phase 3 study evaluating once-weekly dulaglutide 1.5 mg treatment compared with placebo when added to standard of care on a composite endpoint of MACE-3 in adults with T2DM and established CV disease and/or risk factors.1,2

Since the REWIND study did not include active comparators, there is no data available on how dulaglutide would compare with other GLP-1 receptor agonists in regards to cardiovascular outcomes.1

Design

The study evaluated the risk of MACE with once-weekly dulaglutide 1.5 mg treatment compared with placebo when added to standard of care in patients 50 years of age and older with T2DM and CV risk factors.3

The primary CV outcome measure was the first occurrence of the composite MACE-3, which includes death due to CV causes, nonfatal MI, or nonfatal stroke.3

Results

Dulaglutide 1.5 mg significantly reduced MACE-3 when compared to placebo (HR=0.88 [95% CI 0.79, 0.99]; p=.026), demonstrating a decrease in CV events and showing safety in a population that included a majority of participants without established CV disease.2

Other GLP-1 Receptor Agonists CV Outcome Trials

Per regulatory guidance, CV outcome trials were conducted for other marketed GLP-1 receptor agonists. The table below describes the CV outcomes across the GLP-1 receptor agonist class(Table 1).

Abbreviations: BMI = body mass index; CAD = coronary artery disease; CHF = congestive heart failure; CKD = chronic kidney disease; CRF = chronic renal failure; CV = cardiovascular; CVD = cardiovascular disease; ELIXA = the Evaluation of Lixisenatide in Acute Coronary Syndrome trial; EXSCEL = the EXenatide Study of Cardiovascular Event Lowering; GLP-1 RA = glucagon-like peptide-1 receptor agonist; HbA1c = glycated hemoglobin; HF = heart failure; LEADER = the Liraglutide Effect and Action in Diabetes: Evaluation of Cardiovascular Outcome Results; MACE = major adverse cardiovascular events; MACE-3 = 3-component MACE; MACE-4 = 4-component MACE; MI = myocardial infarction; p = p-value; PAD = peripheral artery disease; PVD = peripheral vascular disease; REWIND = Researching Cardiovascular Events with a Weekly INcretin in Diabetes; SUSTAIN 6 = the Trial to Evaluate Cardiovascular and Other Long-term Outcomes with Semaglutide in Subjects with Type 2 Diabetes.

a Definitions of prior CVD vary by study, thus making cross-trial comparisons difficult.

b ELIXA: acute coronary event within 180 days before screening.

c LEADER: CVD, cerebrovascular disease, PVD, CRF, CHF.

d 83.0% established CVD including CKD of stage 3 or higher.

e EXSCEL: 73% at least one prior CV event (70% CAD, 24% PAD, 22% cerebrovascular disease).

f HARMONY: established CVD includes at least one of the following: CAD, cerebrovascular disease, or PAD.

g REWIND: ≥1 of the following, prior MI, ischemic stroke, unstable angina, revascularization, hospitalization for ischaemia-related events, or documented myocardial ischemia.

h Median.

GLP-1 Receptor Agonist CV Outcome Trials Compared to US T2DM Population

Boye et al examined the generalizability of results from CV outcome trials in the US T2DM population with results from the 4 GLP-1 receptor agonist CV outcome trials

  • EXSCEL

  • LEADER

  • REWIND, and

  • SUSTAIN-6.9

When inclusion and exclusion criteria for each trial were applied to the US T2DM population, eligibility were

  • 42.6% for REWIND

  • 15.9% for EXSCEL

  • 13.0% for SUSTAIN-6, and

  • 12.9% for LEADER.9
