Efficacy and Safety Study of Proposed Biosimilar Product Reveliza vs Actilise in Patients With ST-segment Elevation Myocardial Infarction

Thi is is a multi-center, randomized, single-blind, parallel group clinical trial to evaluate the efficacy and safety of the intravenious thrombolysis with Revelise® (GENERIUM, Russia) in comparosin with the Actilyse® (Boehringer Ingelheim Pharma GmbH and Co.KG, Germany) in patients with acute myocardial infarction (MI) with ST-segment elevation on the electrocardiogram (ECG). The thrombolisis was performed within the period of up to 6 hours and from 6 to 12 hours from the MI symptoms onset.

Revelise®, lyophilizate for solution for infusion, 50 mg, is the proposed biosimilar recombinant human tissue plasminogen activator developed by GENERIUM JSC (Russia). All the patients with acute myocardial infurction, enrolled into the study, have been randomised to receive either biosimilar product or a reference produc. The stratification factor was the time from the MI symptoms onset: 1) within the 6 hours and 2) from 6 to 12 hours. Each patient was then followed-up for 3 months, including up to 14 days in an inpatient facility. Coronary angiography was to be performed within the first 24 hours after the administration of the study products, but not earlier than 3 hours after beginning of infusion in case of confirmed thrombolysis (onset of myocardial reperfusion) and immediately - in the absence of reperfusion according to ECG data (ST-segment reduction by less than 50% afterthe infusion start). The patients' condition will be assessed at the scheduled visits.
