Subcutaneous Selatogrel Inhibits Platelet Aggregation in Patients With Acute Myocardial Infarction

ABSTRACT

BACKGROUND - Oral P2Y12 receptor antagonists exhibit delayed onset of platelet inhibition in patients with acute myocardial infarction (AMI). Selatogrel is a potent, highly selective, and reversible P2Y12 receptor antagonist with a rapid onset and short duration of action.

 

OBJECTIVES - This study sought to assess inhibition of platelet aggregation following subcutaneous administration of selatogrel in patients with AMI.

 

METHODS - Patients with AMI were randomized to a single subcutaneous dose of selatogrel of 8 or 16 mg. The primary endpoint was response to treatment (P2Y12 reaction units <100; measured by VerifyNow) at 30 min post-dose. Safety was assessed up to 48 h post-injection.

 

RESULTS - Forty-seven patients received selatogrel 8 mg (n = 24) or 16 mg (n = 23) followed by ticagrelor (n = 43) or clopidogrel (n = 1). The proportion of responders 30 min post-dose was 91% (one-sided 97.5% confidence interval [CI]: 80% to 100%) and 96% (97.5% CI: 87% to 100%) with 8 and 16 mg, respectively (p values for responders >85% target; p = 0.142 and p = 0.009, respectively). Response rates were independent from type of AMI presentation, age, or sex. A similar response rate was observed at 15 min (8 mg: 75% [97.5% CI: 58% to 100%]; 16 mg: 91% [97.5% CI: 80% to 100%]), which was sustained at 60 min post-dose (8 mg: 75% [97.5% CI: 58% to 100%]; 16 mg: 96% [97.5% CI: 87% to 100%]). At 15 min, median P2Y12 reaction units was 51 (range: 4 to 208) for 8 mg and 9 (range: 2 to 175) for 16 mg. Selatogrel was well tolerated, without major bleeding complications.

 

CONCLUSIONS - Single-dose subcutaneous administration of selatogrel in patients with AMI was safe and induced a profound, rapid, and dose-related antiplatelet response. (A Medical Research Study to Evaluate the Effects of ACT-246475 in Adults With Heart Attack; NCT03487445, 2018-000765-36 [EudraCT])
