|---|---|
| Main Objective: To evaluate if Fibrinogen replacement could prevent haemorrhagic complications in ischemic stroke patients with secondary post-rtPA hypofibrinogenemia. To evaluate the efficacy of fibrinogen infusion in stroke patients with secondary post-rtPA hypofibrinogenemia in: - sICH according NINDS, ECASS and SITS classifications. - extracerebral bleedings;Secondary Objective: To evaluate the safety of fibrinogen infusion in stroke patients with secondary post-rtPA hypofibrinogenemia: - Serious thromboembolic adverse events at 7 days after randomization (deep vein thrombosis, pulmonary embolism, myocardial infarct, recurrence of ischemic stroke, MACE defined as all-cause mortality, nonfatal myocardial infarction, andnonfatal stroke) To evaluate the efficacy of fibrinogen infusion in stroke patients with secondary post-rtPA hypofibrinogenemia in the clinical outcome defined as: - National Institutes of Health Stroke Scale score (NIHSS) at day 7 - disability at 3 months, assessed with the modified Rankin Scale (mRS). Good outcome is considered as mRS 0-2 - To evaluate the diagnosis of hyperfibrinolysis detected with Rotation thromboelastometry (ROTEM) in the whole ischemic stroke population randomized in the RCT (200 patients) - To correlate hyperfibrinolysis with cerebral bleeding in the whole ischemic stroke population and in each arm;Primary end point(s): To evaluate the efficacy of fibrinogen infusion in stroke patients with secondary post-rtPA hypofibrinogenemia in reducing the rate of ICH defined as parenchymal hematoma (PH1, PH2 and remote ones) To evaluate the efficacy of fibrinogen infusion in stroke patients with secondary post-rtPA hypofibrinogenemia in: - sICH according NINDS, ECASS and SITS classifications. - extracerebral bleedings;Timepoint(s) of evaluation of this end point: 24 hours after the rtPA infusion, or earlier in case of clinical deterioration, and on day 7 (or at discharge, if earlier). | — |

| Timepoint(s) of evaluation of this end point: For symptomatic cerebral haemorrhage at 24h and 7 days, as well as extracerebral haemorrhages; Clinical severity measured as NIHSS score at baseline and day 7; disability at 3 months 90 days (90 + 7) will be defined according to the mRS scale, with a good outcome defined as mRS 0-2.;Secondary end point(s): To evaluate the safety of fibrinogen infusion in stroke patients with secondary post-rtPA hypofibrinogenemia: - Serious thromboembolic adverse events at 7 days after randomization (deep vein thrombosis, pulmonary embolism, myocardial infarct, recurrence of ischemic stroke, MACE defined as all-cause mortality, nonfatal myocardial infarction, andnonfatal stroke) To evaluate the efficacy of fibrinogen infusion in stroke patients with secondary post-rtPA hypofibrinogenemia in the clinical outcome defined as: - National Institutes of Health Stroke Scale score (NIHSS) at day 7 - disability at 3 months, assessed with the modified Rankin Scale (mRS). Good outcome is considered as mRS 0-2 - To evaluate the diagnosis of hyperfibrinolysis detected with Rotation thromboelastometry (ROTEM) in the whole ischemic stroke population randomized in the RCT (200 patients) - To correlate hyperfibrinolysis with cerebral bleeding in the whole ischemic stroke population and in each arm | — |
