Brief Summary:
This study will randomize patients recently discharged from the hospital with a confirmed diagnosis of type 1 acute myocardial infarction (Thygesen et al. 2018) and having additional cardiovascular risk factors.

Condition or disease Intervention/treatment Phase
Acute Myocardial Infarction Combination Product: Selatogrel Combination Product: Placebo Phase 3

Detailed Description:
The purpose of this study is to assess the clinical efficacy of selatogrel when self-administered upon occurrence of symptoms suggestive of an acute myocardial infarction (AMI) in participants at risk of having a recurrent AMI.

Arms and Interventions
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Arm Intervention/treatment
Experimental: Selatogrel
Study treatment administration may occur at any time between the randomization visit and the final study visit when the participant experiences symptoms suggestive of an acute myocardial infarction. Study treatment administration triggers protocol pre-defined assessments or visits.
 Combination Product: Selatogrel

Selatogrel is a reversible P2Y12 receptor antagonist for subcutaneous administration. Selatogrel will be administered as a liquid formulation in a sealed prefilled syringe in an autoinjector forming an integral ready-to-use, single-dose drug delivery system.

Participants will self-administer 16 mg of selatogrel subcutaneously with the autoinjector upon occurrence of symptoms suggestive of an acute myocardial infarction. Self-administration encompasses the use of the autoinjector by another person (e.g., partner, close relative, friend, caregiver) who may be called for help during the emergency situation of a suspected AMI.

Other Name: ACT-246475
Placebo Comparator: Placebo
Study treatment administration may occur at any time between the randomization visit and the final study visit when the participant experiences symptoms suggestive of an acute myocardial infarction. Study treatment administration triggers protocol pre-defined assessments or visits.
 Combination Product: Placebo

Placebo will be administered as a liquid formulation in a sealed prefilled syringe in an autoinjector forming an integral ready-to-use, single-dose drug delivery system.

Participants will self-administer placebo subcutaneously with the autoinjector upon occurrence of symptoms suggestive of an acute myocardial infarction. Self-administration encompasses the use of the autoinjector by another person (e.g., partner, close relative, friend, caregiver) who may be called for help during the emergency situation of a suspected AMI.


Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Clinical status as assessed by a 6-point ordinal scale [ Time Frame: Total duration: up to 7 days ]

    The clinical status will be assessed using a 6-point ordinal scale after any study treatment self-administration. Only the worst clinical outcome will be retained as the primary efficacy outcome. The 6 mutually exclusive outcomes ranked from worst to best are:

    1. Death (all causes), within 7 days after study treatment administration.
    2. Acute myocardial infarction with compromised electro-hemodynamics, within 2 days after study treatment administration.
    3. ST-Elevation Myocardial Infarction (STEMI), within 2 days after study treatment administration.
    4. High-risk Non-ST-Elevation Myocardial Infarction (NSTEMI), within 2 days after study treatment administration.
    5. NSTEMI with peak cardiac troponin greater than 10 times upper limit of normal, within 2 days after study drug administration.
    6. None of the above

  2. Occurrence of Type 3 or 5 treatment-emergent bleeding events according to the Bleeding Academic Research Consortium (BARC) definition [ Time Frame: Total duration: up to 2 days ]

    The number of:

    • Type 3 treatment-emergent bleeding events and
    • Type 5 treatment-emergent bleeding events

    will be assessed according to the Bleeding Academic Research Consortium (BARC) definition (Mehran et al. 2011), within 2 days after study treatment administration.

    The Bleeding Academic Research Consortium (BARC) definitions are:

    • Type 3, bleeding is divided into 3 categories, a through c, and includes clinical, laboratory, and/or imaging evidence of bleeding with specific healthcare provider responses.
    • Type 5, bleeding is fatal.


Secondary Outcome Measures :
  1. Occurrence of death, non-fatal acute myocardial infarction, hospitalization or unplanned emergency department visit for heart failure (Composite endpoint) [ Time Frame: Total duration: up to 30 days ]
    Occurrence death, non-fatal acute myocardial infarction, hospitalization or unplanned emergency department visit for heart failure within 30 days after any self-administration.
