Brief Summary:
Objective: to evaluate the efficacy and safety of intra-arterial intrathrombus administration of the recombinant non-immunogenic staphylokinase (Fortelyzin®) in patients with acute limb ischemia (ALI) vs surgery.
Detailed Description:
Fortelyzin® (the active substance Forteplase) is a recombinant non-immunogenic staphylokinase with high fibrinselective thrombolytic activity. In a multicentre, randomised clinical trial in patients with ST-segment elevation myocardial infarction (FRIDOM), non-immunogenic staphylokinase was administered as a single intravenous bolus of 15 mg in all patients, regardless of bodyweight, and showed similar high reperfusion patency and fewer minor bleeding events compared with tenecteplase, as well as the absence of neutralising IgGs. Results of the multicentre, randomised clinical trial in patients with an acute ischaemic stroke (FRIDA) suggested that the non-immunogenic staphylokinase administrated as a single intravenous bolus of 10 mg in all patients within the 4-5 h after the onset of symptoms is non-inferior to alteplase. Mortality, symptomatic intracranial haemorrhage, and serious adverse events did not differ between treatment groups.
Mortality in the ALI continues to be high. According to the Guidelines on the management of patients with ALI, intravenous systemic thrombolysis is ineffective in patients with this condition. In contrast, catheter-directed thrombolysis based on the principle that activation of fibrin-bound plasminogen to the active enzyme plasmin is the most effective approach of lysing pathologic thrombi in the lower extremities of I-II b degree of ALI (Evidence level I-A).
So the main objective of this study is to evaluate the efficacy and safety of intra-arterial intrathrombus administration of the recombinant non-immunogenic staphylokinase (Fortelyzin®) in patients with ALI vs surgery.
