Dulaglutide reduces:
- Myocardial infarction
- Stroke
- Cardiovascular death
Particularly beneficial in patients with established ASCVD or multiple risk factors.
Major Trial
REWIND Trial:
- Reduced major adverse cardiovascular events
- Included many patients without established ASCVD
- Demonstrated strong primary prevention benefit
Dosing
- Once-weekly subcutaneous injection
- No oral formulation
- Gradual dose escalation improves tolerability

Dulaglutide:
- Strong ASCVD reduction
- Modest weight loss
- Minimal heart failure benefit
- Strong heart failure benefit
