Overview
The purpose of the study is to provide a first assessment of safety, tolerability and efficacy of Ir-CPI, administered on top of standard-of-care, on secondary brain injury in patients with spontaneous intracerebral haemorrhage.
Eligibility
Inclusion Criteria:
- Male or female patients aged ≥ 18 years.
- Written informed consent obtained before any study assessment. If the patient is not able to give the informed consent personally, consent by a legal representative as defined by local law and regulation is acceptable.
- First-ever, spontaneous, supratentorial intracerebral haemorrhage in cerebral cortex or deep brain structures (putamen, thalamus, caudate, and associated deep white matter tracts) with a volume ≥ 5 mL and ≤ 60 mL determined by non-contrast CT scan.
- Patients with Glasgow Coma Scale (GCS) best motor score no less than 5.
- Modified Rankin Scale (mRS) score 0-2 prior to ICH symptom onset.
Exclusion Criteria:
- History of personal or familial bleeding disorders; including prolonged or unusual bleeding.
- Known deficiency in factor XII (FXII) or haemophilia type A (FVII) or type B (FIX) or type C (FXI).
- Infratentorial (midbrain, pons, medulla, or cerebellum) ICH.
- Secondary ICH due to aneurysm, brain tumour, arteriovenous malformation, thrombocytopenia, coagulopathy, acute sepsis, traumatic brain injury (TBI), or disseminated intravascular coagulation (DIC).
- Planned neurosurgical hematoma evacuation or other urgent surgical intervention (i.e., surgical relief of increased intracranial pressure) on initial presentation.
- Planned anticoagulation reversal treatment.
- Patients with intraventricular haemorrhage (IVH) having a Graeb score of >3 on initial presentation. Patients must not have blood in the 4th ventricle and may only have blood in the 3rd ventricle in the absence of ventricular expansion. Trace or mild haemorrhage in either or both lateral ventricles is permitted. Patients with hydrocephalus determined radiologically on initial presentation are excluded regardless of Graeb score.
- Use of immunosuppressive or immune-modulating therapy at admission (e.g., steroids, methotrexate, monoclonal antibodies, etc).
- Patients with active systemic bacterial, viral or fungal infections.
- Women of childbearing potential.
- Have a body weight > 120 kg at screening.
- Severe renal impairment (eGFR < 30 mL/min/1.73 m2).
