Combined Treatment With Alteplase (Rt-PA) and Cerebrolysin® in Acute Ischemic Hemispheric Stroke (CERE-LYSE-1)

A Prospective, Randomised, Placebo Controlled, Double Blind Trial About Safety and Efficacy of Combined Treatment With Alteplase (Rt-PA) and Cerebrolysin® in Acute Ischemic Hemispheric Stroke

It should be shown that Cerebrolysin in combination with Alteplase, the medication that should recover the blood flow through the brain, is an effective and save medication to treat ischeamic stroke.

Study Overview

• Status: Completed
• Conditions: Stroke
• Intervention / Treatment: Drug: Cerebrolysin; Drug: 0.9% Saline Solution

Detailed Description

The current trial should evaluate a combined treatment using Cerebrolysin immediately after thrombolysis to guarantee that the neurotrophic components are able to reach the endangered brain areas efficiently. An early start of treatment should guarantee rescue of most of the neurons reducing the overall damage.The study follows the design of pure thrombolytic trials to investigate, if the early neuroprotective treatment with Cerebrolysin is able to improve the overall outcome of patients at the day 90 evaluation visit. Due to the initial findings special emphasis will be also put on analysing the speed of recovery.

Participation Criteria

Eligibility Criteria

• Ages Eligible for Study: 18 years to 80 years (Adult, Older Adult)
• Accepts Healthy Volunteers: No
• Genders Eligible for Study: All

Description

Inclusion Criteria:

• Female or male inpatients.
• Age: 18-80 years.
• If female, patient must not be pregnant
• Clinical diagnosis of ischemic stroke causing a measurable neurological deficit defined as impairment of language, motor function, cognition and/or gaze,vision or neglect. Ischemic stroke is defined as an event characterized by the sudden onset of an acute focal neurologic deficit presumed to be due to cerebral ischemia after CT scan excludes haemorrhage.
• Onset of symptoms within 3 hours prior to initiation of rt-PA administration.
• Stroke symptoms are to be present for at least 30 minutes and have not significantly improved before treatment. Symptoms must be distinguishable from an episode of generalized ischemia (i.e. syncope), seizure or migraine disorder.
• Patient is willing to participate voluntarily and to sign a written patient informed consent. Informed consent will be obtained from each patient or the subject's legally authorized representative or relatives, or deferred where applicable, according to the regulatory and legal requirements of the participating country.
• Patients who are unable to sign but who are able to understand the meaning of participation in the study may give an oral witnessed informed consent. These patients have to make clear undoubtful that they are willing to participate voluntarily and must be able to understand an explanation of the contents of the information sheet. A written consent has to be obtained as soon as possible.
• Willingness and ability to comply with the protocol.

Exclusion Criteria:

• Evidence of intracranial haemorrhage (ICH) on the CT-scan
• Violation of inclusion criteria not approved by clinical study director or study safety officer
• Failure to perform or to evaluate screening or baseline examinations
• Hospitalisation (except for study purposes) or change of concomitant medication 4 weeks prior to screening or during screening period
• Participation in another therapeutic clinical trial 3 months before baseline
• Patients with any history of prior stroke and concomitant diabetes
• Prior stroke within the last 3 months
• Platelet count of below 100x103/mm3
• Blood glucose <50 or >400 mg/dl (<2.77 or >22.15 mmol/L)
• Known haemorrhagic diathesis
• Manifest or recent severe or dangerous bleeding
• Known bacterial endocarditis, pericarditis
• Acute pancreatitis
• Documented ulcerative gastrointestinal disease during the last 3 months, oesophageal varices, arterial-aneurysm, arterial/venous malformation
• Neoplasm with increased bleeding risk
• Severe liver disease, including hepatic failure, cirrhosis, portal hypertension, oesaphageal varices) and active hepatitis
• Major surgery or significant trauma in past 3 months
• Lab values seriously abnormal, and/or more than 2 lab values abnormal not approved by clinical study director or study safety officer
• Serious drug allergies
• Hypersensitivity to one of the components of the drug
• Severe renal impairment
• Systolic blood pressure >185 mmHg or diastolic blood pressure >110 mmHg, or aggressive management (IV medication) necessary to reduce BP to these limits
• Recent (less than 10 days) traumatic external heart massage, obstetrical delivery, recent puncture of a non-compressible blood-vessel (e.g. subclavian or jugular vein puncture)
• Chronic intoxication or chronic substance use disorder with pharmaceuticals, drugs, alcohol or industrial poisons
• Symptoms of ischemic attack began more than 3 hours prior to start of thrombolytic therapy or if time of symptom onset is unknown
• Minor neurological deficit or symptoms rapidly improving before start of infusion
• Severe stroke as assessed clinically (e.g. NIHSS >25) and/or by appropriate imaging techniques
• Epilepsy or epileptic seizure at onset of stroke
• Symptoms suggestive of subarachnoid haemorrhage, even if the CT-scan is normal
• Known history of or suspected intracranial haemorrhage
• Suspected subarachnoid haemorrhage or condition after subarachnoid hemorrhage from aneurysm
• Any history of central nervous system damage (i.e. neoplasm, aneurysm, intracranial or spinal surgery)
• Haemorrhagic retinopathy, e.g. in diabetes (vision disturbances may indicate haemorrhagic retinopathy)
• Administration of heparin within the previous 48 hours and a thromboplastin time exceeding the upper limit of normal for laboratory
