About this study

Official title: CERebrolysine Effect on Blood-brain Barrier / Endothelium Integrity During Reperfusion Therapy of acUte Ischemic Stroke (CERBERUS Study)

The study investigates whether Cerebrolysin stabilizes blood-brain barrier integrity in a manner that can be monitored using serum levels of the principal tight junction proteins, e.g., occludin (OCL), claudin-5 (CLN), and zonula occludens-1 (ZO-1), or other molecules known to be involved in BBB degradation, e.g., S100B and whether it protects against hemorrhagic transformation in ischemic stroke patients after reperfusion therapy (i.e. thrombolysis and/or mechanical thrombectomy).

Read the detailed description

Hemorrhagic transformation (HT) of ischemic stroke can be identified in 3-40% of patients. The incidence varies depending on the definition used and the studied population. The severity of HT can be described using clinical and radiological tools and classified as asymptomatic/symptomatic, according to European Cooperative Acute Stroke Study classification and Heidelberg Bleeding Classification. Breakdown of the blood-brain barrier (BBB) is associated with an increased risk of developing a hemorrhagic transformation (HT) of ischemic stroke. In patients who received reperfusion therapy (thrombolysis, mechanical thrombectomy), secondary HT had a negative influence on the clinical course and outcome.

Tight junction (TJ) proteins are important cell adhesion components that stabilize endothelium cells lining and are responsible for maintaining the BBB integrity.

Biomarkers of BBB damage that can be evaluated during the early phases of stroke might be useful for predicting the risk of HT. Such biomarkers could also facilitate the decision of whether to begin thrombolytic therapy in acute ischemic stroke patients. Experimental data support the evidence for protective effect of Cerebrolysin on BBB integrity. Moreover, it diminished and reversed negative effect of recombinant tissue plasminogen activator (rtPA) used as thrombolytic agent on endothelial cells integrity. Cerebrolysin stabilized tight junction proteins expression: occludin, claudin-5 and zona occludens 1 (ZO1). In our previous study we have found that circulating TJs predict HT in ischemic stroke patients. Clinically evident HTs were associated with increased concentrations of occludin and S100B, an increase in the claudin-5/ZO-1 ratio, and a decreased level of vascular endothelial growth factor (VEGF). Claudin-5 levels also correlated with HT occurrence when estimated within 3 hours of stroke onset. The protective effects of Cerebrolysin were already clinically evidenced, however there are no available studies using biomarkers of BBB.

Aim of the study

We aim to investigate whether Cerebrolysin stabilizes BBB integrity in a manner that can be monitored using serum levels of the principal TJ proteins, e.g., occludin (OCL), claudin-5 (CLN), and zonula occludens-1 (ZO-1), or other molecules known to be involved in BBB degradation, e.g., S100B and whether it protects against HT in ischemic stroke patients after reperfusion therapy.

Study design

A prospective longitudinal study will be performed in ischemic stroke patients who:

  1. are included for reperfusion therapy (intravenous thrombolysis and/or mechanical thrombectomy - control (group A),
  2. are included for reperfusion therapy (intravenous thrombolysis and/or mechanical thrombectomy plus Cerebrolysin (group B)
  3. are not referred to reperfusion therapy nor Cerebrolysin (group C).

All patients with NIHSS score > 8 will receive 30 ml Cerebrolysin in 500 ml of buffered crystalloid solution intravenously initiated within 12 hours from symptoms onset.

Whole blood samples will be withdrawn at the admission, then within 1 to 3 days after stroke onset and at 7th day after stroke onset or when the endpoint will be reached by the patient. Occludin, claudin 5 and ZO-1 concentrations will be analyzed by means of home-made enzyme-linked immunosorbent assay.

Endpoint will include clinical worsening (increase in the NIHSS by > 4 points), radiologically evident hemorrhage or radiologically evident brain edema at control CT performed within 1 to 3 days after stroke onset.

Standard head CT will be performed in all patients at the admission, within 1 to 3 days after stroke onset, after worsening of clinical status and additionally when the differentiation between hemorrhage and contrast staining will be required in thrombectomy patients. Hemorrhagic transformation of ischemic stroke will be classified according to Table 1.

Clinimetric evaluation of all patients will include NIHSS every day for 7 days and at day 30. Modified Rankin scale (mRS) will be evaluated at visit 1,2,3,4 and 5; Barthel index at visit 4 and 5 and Montreal Cognitive Assessment Test at visit 5.

All patents will undergo current American Heart Association Guidelines for the Early Management of Patients with Acute Ischemic Stroke.

Expected results It is expected that Cerebrolysin can stabilize blood-brain barrier in ischemic stroke patients treated with reperfusion therapies via remodelling of tight junction proteins between endothelial cells. Such an effect measured by the levels of circulating tight junction proteins can translate into prevention of hemorrhagic transformation. To summarize, Cerebrolysine can guard blood-brain barrier integrity in ischemic stroke (Cerberus effect).

What does the primary outcome measure?

National Institute of Health Stroke Scale (time frame: every day for 7 days after stroke onset). The study lists 9 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT06078215, which also lists 6 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Oct 2023.
