Clinical Trial Summary

Study Description:

Background: Well-known fact that the number of cardiovascular diseases is on the rise during influenza epidemic. It is conceivable that influenza may precipitate plaque rupture, increase cytokines with central roles in plaque destabilization and trigger the coagulation cascade. A number of studies have shown that the risk of cardiovascular complications (ACS, stroke, CHF decompensation, cardiac arrhythmias) seem to be reduced following influenza vaccination. The Influenza Vaccination After Myocardial Infarction study data published in September 2021 have demonstrated a significant decrease of mortality (by 40%) during 1 year of follow-up in patients with myocardial infarction (MI) who has been vaccinated during the first 72 hours.

Objective: the objective is to find out whether influenza vaccination protects against cardiovascular events and death in ACS & CHF patients vaccinated during hospitalization Methods: Population: 400 patients aged 65 and older with acute coronary syndrome are randomized 1:1 and followed up via telephone calls and registries (AIS "Mortality").

Patients will be included in the study in cardiology departments № 1, 2, 3, 5, 6 of the State Budgetary Healthcare Institution "Samara Regional Clinical Cardiology Dispensary named after V.P. Polyakov" Intervention: Influenza vaccination. Control: group of unvaccinated patients. Planned study period is 1 year.

Description:

Detailed Description:

Name of investigational treatment: Influenza vaccine ("Ultrix Quadri"™) Planned study period:

October - December 2021 ((influenza season) Long-term follow up to 365 days from the moment of vaccination of the last included patient (approximately November-December 2022) via phone calls.

Methodology: vaccination will be start after informed consent on the day of leaving hospital with "Ultrix Quadri"™ vaccine Intervention Model: Parallel Assignment Number of subjects: 400 Number of vaccinated patients is 200 Number of patients with placebo is 200 Primary endpoint: сomposite of all-cause death, MI, or stent thrombosis at 12 months Secondary endpoints

• The number of participants with all-cause death till 1 year (key secondary outcome)

• The number of participants with myocardial infarction till 1 year (key secondary outcome)

• The number of participants with stent thrombosis till 1 year (key secondary outcome)

• The number of participants with cardiovascular death till 1 year (key secondary outcome)

• The number of participants with a new revascularization till 1 year

• The number of participants with cardiovascular death, a new myocardial infarction or stent thrombosis (first occurring) till 1 year

• The number of participants with stroke, including transient ischemic attack (TIA) till 1 year

• The number of participants with hospitalization for heart failure till 1 year

• The number of participants with hospitalization for arrhythmia till 1 year

• Safety of vaccination (incidence of side effects)

Follow up by telephone and registry information (AIS "Mortality"): the follow up for endpoints will be performed using telephone contacts with the patients or first degree relatives.

Purpose of phone calls:

• to assess the safety of vaccination the day after vaccination (T1) 7 (± 1) day after vaccination (T2)

• to study the effectiveness 365 (± 5) days after vaccination (T3)

Reporting for adverse events: The patients will be informed to contact the investigator or study nurse if any adverse event should occur during this timeframe.

Study Start Date: September 2021 Actual Primary Completion Date (safety assessment): December 2021 Actual Study Completion Date (efficiency mark): December 2022 Experimental Drug: influenza vaccine Ultrix Quadri Standard influenza vaccine administered as a deep subcutaneous injection at one occasion per subject.

The experimental drug is not administered to patients in the control group.
