Title: 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
Brief Summary: 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.

A: Inclusion Criteria:

* Female or male inpatients.

* 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.

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.
