Basic Information

• Recruitment Status: COMPLETED

Brief Summary

The goal of the study was to evaluate the effect of single administration of RPH-104 at 80 mg and 160 mg on parameters of systemic inflammation and outcomes of the disease in subjects with ST-segment elevation myocardial infarction (STEMI)

Detailed Description

After signing the informed consent form, the investigator assessed the subject's eligibility for the study. The following procedures were performed during the screening: collection of medical history, recording previous and concomitant therapy, demographic data, recording 12-lead ECG findings on which STEMI diagnosis was based, recording date and time of STEMI symptom development, recording date, time and results of coronary angiography (CAG) at admission to the study site, measurement of blood neutrophil count, vital signs, physical examination including measurement of body weight (if hospital bed is available), blood sampling for hematology, biochemistry, determination of concentration of hsCRP and brain natriuretic peptide (BNP; N-terminal (NT)-pro hormone brain natriuretic peptide (NT-pro-BNP)), for females with retained reproductive potential - pregnancy test (test strips).

The subjects meeting selection criteria were randomized to one of the three groups (in 1:1:1 ratio) for single subcutaneous administration of RPH-104 80 mg, RPH-104 160 mg or placebo.

Screening, randomization and administration of the study products were made on the same (first) study day.

Further 4-week (28-day) clinical follow-up and additional 6- and 12-month clinical follow-up period were performed.

The end of clinical part of the study was the date of the last visit of the last subject within additional 12-month clinical follow-up.

The maximum number of screened patients was planned to be 146 subjects, 102 subjects were randomized, 34 subjects per group.

Eligibility Criteria

Inclusion Criteria

• Subjects who gave voluntary written Informed consent to participate in the study and to follow all Protocol procedures.
• STEMI diagnosis defined as chest pain or its equivalent with ECG findings evidencing ST elevation (>1 mm) in two or more consecutive leads or acute left bunch branch block according the investigator's judgement.
• Percutaneous coronary intervention (PCI) with stenting was performed within no more than 12 hours after onset of chest pain or its equivalent and randomization was performed in no more than 12 hours after PCI (overall within 24 hours of onset of chest pain or equivalent).
• Consent of female subjects with childbearing potential defined as all female subjects with physiological potential to conceive, to use highly effective contraceptive methods throughout the study starting from screening (signing Informed Consent Form) and negative pregnancy test.

Highly effective contraceptive methods include combination of two of the following methods (a+b or a+c or b+c):

1. oral, injection or implanted hormonal contraceptives; in case of oral contraceptives, the female subjects should administer the same product for at least 3 months prior to the study therapy;

2. intrauterine device or contraceptive system;

3. barrier methods: condom or occlusive cap (diaphragm or cervical cap / vaginal fornix cap) with spermicidal foam/gel/film/cream/vaginal suppository

• Ability and willingness of the subject, according to the reasonable investigator's judgment, to attend the study site at all scheduled visits, undergo the study procedures and follow the Protocol requirements including subcutaneous injections by qualified site personnel.

Exclusion Criteria

• Hypersensitivity to test product (RPH-104) and/or its ingredients/excipients.
• Pregnancy and breastfeeding.
• Verified chronic heart failure (The American Heart Association / The American College of Cardiology (AHA/ACC) C-D class, New York Heart Association (NYHA) Functional class (FC) III-IV)
• Pre-existing severe valvular heart disease according to the investigator's assessment.
• Pre-existing left ventricular (LV) dysfunction (ejection fraction (EF)<40%)
• History of STEMI
• Complications of acute myocardial infarction (MI) in the form of acute left ventricular failure and cardiogenic shock defined as stable blood pressure decrease (SBP<90 mm Hg) associated with signs of hypoperfusion as well as cases when inotropic and/or mechanical support is required to maintain SBP; and / or unstable hemodynamics.
• Active infections (acute or chronic); active tuberculosis.
• Recent (less than 5 half-life periods) or current administration of colchicine, as well as agents with an immunosuppressant mechanism of action, including, but not limited to:

glucocorticoids at doses of > 1 mg/kg of methylprednisolone equivalent, tumor necrosis factor-alfa (TNFα) blockers, Interleukin-1 (IL-1) and other biological drugs, cyclosporine and other immunosuppressants. Non-steroidal anti-inflammatory drugs (NSAIDs) are allowed.

• Immunization with live vaccines within 90 days prior to the study product administration.
• Chronic systemic autoimmune or autoinflammatory diseases
• Suspected necessity in cardiosurgery.
• Oncology (or diagnosis of oncology within the last 5 years).
• History of organ transplantation or necessity in transplantation at the screening initiation or scheduled transplantation during the study.
• Neutropenia (absolute neutrophil count <1800/mm^3).
• Participation in another clinical study within the previous 3 months prior to Screening visit.
• Other medical (including mental) conditions or abnormal laboratory findings which may increase the risk for the subject associated with the study participation or administration of the study products or which may affect interpretation of the study results and, according to the investigator, render the subject ineligible for the study.*

*If, in the Investigator's opinion, administration of a non-live COVID-19 (SARS-CoV-2) vaccine increases the risk for the patient related to his/her participation in the study, the Investigator can make a decision not to include this patient into the study.
