rFVIIa in ICH in Patients Treated With Anticoagulants or Anti-Platelets

Phase 2 Results N/A

Trial Description

Evaluation of efficacy and safety of recombinant factor VIIa versus standard therapy in preventing early haematoma growth in spontaneous acute intracerebral haemorrhage in patients treated with oral anticoagulants or antiplatelets agents

Detailed Description

Intracerebral hemorrhage (ICH) is the deadliest, most disabling, and least treatable form of stroke. Approximately 40% of patients die within 1 month of ICH onset, and two-thirds of survivors never regain functional independence. Though guidelines for supportive care exist, there is currently no treatment that has been shown in a randomized-controlled trial to definitely improve outcome after ICH. Hematoma volume is a critical determinant of mortality and functional outcome after ICH, and early hematoma growth may be an important cause of early neurological deterioration.
Considerable clinical interest has been given to the relationship between antiplatelet and antithrombotic treatment and ICH.
The reported incidence of major bleeding events in patients undergoing antithrombotic treatment is 5-11/1,000 patients/year, while the overall range of hemorrhages is about 62/1,000 patients/year.In the patients treated with antithrombotic drugs (oral anticoagulants or antiplatelets agent) the incidence rate of ICH has been shown higher than in the general population. Moreover, the mortality rate for both spontaneous and post-traumatic events is higher in antithrombotic treated patients than in controls. [14,15] rFVIIa has been successfully used to control ICH in patients with hemophilia or other coagulation disorders, and can arrest intraoperative bleeding and reverse coagulopathies in patients undergoing neurosurgical procedures.[19] rFVIIa has also been reported to prevent or minimize refractory bleeding in non-coagulopathic patients.

Outcomes

Type Measure Time Frame Safety Issue
Primary Efficacy: change in ICH volume from prior to dosing to 24 hours. Safety: occurrence of clinical adverse events (thromboembolic events, mortality).
Secondary Difference between groups on the modified Rankin Scale, the Barthel Index (BI), the Extended Glasgow Scale (EGCS), and the National Institute of Health’s Stroke Scale (NIHSS) at one and three month follow up.
