The goal of this clinical trial is investigate the efficacy of a neuro/vascular-protective treatment with the drug Cerebrolysin in patients with acute ischemic stroke. starting immediately after completion of a EVT therapy. The main question the study aims to answer is: If a 10 days treatment with the neuro/vascularprotective drug Cerebrolysin (30 ml/day as intravenous infusion) is able to increase the overall outcome of EVT therapy? Participants will receive intravenous treatment with Cerebrolysin (30 ml/day) starting immediately after thrombolytic therapy and being continued for 10 consecutive days as one single daily infusion. The modified Rankin Scale (mRS) 90 days after onset of symptoms will be investigated, but also the improvement in other ratings as well as the time course of the improvement. In addition to the clinical outcome measures the study will assess neuroimaging perfusion CT-Perfusion parameters to evaluate possible direct improvement in microcirculation that might be an additional mechanism of action of cerebrolysin. CT-Perfusion being done immediately after EVT will provide ability to stratify the data according to non-favorable CT-Perfusion parameters after EVT versus favoravle.
9.1. Overall Study Design and Plan-Description The study will be conducted as a single center, trial. In patients with AIS after EVT, according to the consensus guidelines, the study drug (Cerebrolysin) will be administered as IV-infusion over 30 minutes. First treatment will be administered up to 3 hours after completion of the EVT intervention.. First treatment will be given after a post EVT CT-Perfusion was performed. The treatment with Cerebrolysin will be repeated until day 10 as a single daily infusion. Patients may be inpatients as long as deemed necessary by the principal investigator. The observation period will last 9 (±14) month days after the administration of study medication. Patients recruited but not treated with the study drug due to various reasons or who do not receive the total dose of study medication will also be observed for 9 month if they survive. The study is planned to be started in October 2023 (first patient in) and should be finished by June 2024. The study will be conducted at the Shaare Zedek Medical Center. Treatments must be performed by a physician specialized in neurological care. 9.2. Discussion of Study Design, Including the Choice of Control Groups 9.2.1. Randomization No Randomization will be needed. 9.2.2. Treatment groups Cerebrolysin has a neuro/vascularprotective mode of action. It is assumed, based on preclinical data and on first findings from clinical studies, that treatment with Cerebrolysin may be able to prevent neuronal death after brain ischemia. Therefore one group of patients should receive intravenous treatment with Cerebrolysin (30 ml/day) starting after post EVT CT-Perfusion that will be performed not later than 3 hours from completion of EVT. Treatment will be continued for 10 consecutive days as one single daily infusion. 9.2.3. Efficacy assessment tools The main goal of this study is to assess efficacy. Potential effects of EVT will be evaluated by using the mRS score at day 90 (primary endpoint). For the list of further endpoints see chapter 9.5.1.1.2. Secondary efficacy parameters. Efficacy parameters: The NIH Stroke Scale will be performed at baseline, 1 hours (after Drug administration), 2 hours (after), 24 hours (after), Day 5, Day 10, on Day 7 and/or discharge, 30 days, 90 days and 9 month after the start of treatment. The Modified Rankin Scale on Day 7 and/or discharge, 30 days, 90 days and 9 month. All investigations should be done by an MRS and NIHSS certified investigator. Length of stay in hospital in both groups will be assessed as well. The patient termination record will be performed at 9 month or if a patient decides to withdraw the consent for further remaining in the study. Additional to clinical efficacy parameters the all outcomes measurements will be stratified by post-EVT CT-Perfusions measurements with a favourable and ubfavorable CT-Perfusion group. 9.2.4. Duration of the treatment No later the 3 hours post EVT patient is brought to the MRI for ASLPV measurement the first infusion of the study medication (Cerebrolysin/Placebo) is administered as an IV-infusion over a time period of 30 min while patient is undergoing further MRI imaging with another ASLPV measurement at the end of the treatment . The treatment with Cerebrolysin will be repeated until day 10 as a single daily infusion every 24 +/- 2h. Patients may be inpatients as long as deemed necessary by the principal investigator. The observation period will last 9 month after the admission to the hospital with symptoms of acute ischemic stroke, qualifying for the study. Patients randomized, but not treated with Cerebrolysin because of any given reason or who do not receive the total dose of study medication, will also be observed for 9 month if they survive. 9.2.5. Choice of Cerebrolysin dosages A dosage of 30 ml of Cerebrolysin per day over a period of 10 days has been chosen based on the results of previous preliminary trials in various indications, proofing to be the most efficacious dose. This finding is in compliance with data from preclinical studies, showing highest degree of neuroprotection in comparable dose ranges. An early start of treatment after EVT should ensure maximum rescue of neurons in the acute stage due to the neuro/vasculareprotective mode of action. The prolongation of the therapy over ten days should help to induce repair processes due to the neurotrophic properties of Cerebrolysin inducing neuronal sprouting reaction and maybe even proliferation and differentiation of neuronal progenitor cells. Drug profile Cerebrolysin is a brain derived peptide preparation produced by a standardised enzymatic breakdown of lipid-free brain proteins. It consists of approximately 25% of low molecular weight peptides, based on the total nitrogen content, stabilised with amino acids. The drug is free from proteins, lipids and antigens and is administered by intravenous infusion (Summary, see also Investigator Brochure). Qualitative and quantitative composition 1. ml contains 215.2 mg porcine brain derived peptide preparation (Cerebrolysin concentrate) in aqueous solution. Pharmaceutical form Cerebrolysin is a solution for injection/concentrate for solution for infusion. The vials ready for infusion have to be stored at room temperature (not over 25°C) in a dry place away from light. 9.2.6. Treatment period The study drug will be administered first time as intravenous-infusion (30 ml of Cerebrolysin in a total volume of 100 ml, diluted with physiological saline) over 30 minutes not later the 3 hours after EVTand after psot EVT CT-Perfusion imaging.. Treatment will be repeated on further 9 consecutive days (total of 10 administrations) if possible always as a morning dose. Patients may be inpatients as long as deemed necessary by the principal investigator. Patients are coming to hospital for all visits up to Day 10, if they can be discharged from hospital earlier. The observation period will last 9 month (±1week) after the first administration of study medication. Patients randomized but not treated with Cerebrolysin or who do not receive the total treatment course of study medication will also be observed for 9 month. 9.3.

Conditions developing during the course of the study listed in the exclusion criteria as well as protocol deviations do not necessarily lead to the patient's withdrawal but should be properly documented. Patients who are withdrawn from the study due to AEs will be treated according to standard clinical strategies and will be followed up until they are resolved or stabilised or until a plausible explanation for the cause of the event has been found. All pertinent information concerning the outcome of the Adverse Event will be documented in the case report form. In accordance with the informed consent and the Declaration of Helsinki, the patient may discontinue the study at any time without any penalty or loss of benefits to which the patient is otherwise entitled. Reason(s) for a premature termination should be documented in the case report form. The final examination should be performed in such cases for safety reasons. Patients discontinuing the study must be fully documented up to the time of discontinuation. Both the discontinuation of the treatment and the reason why the treatment was prematurely terminated must be recorded in the case report form. In addition, time, date and circumstances should also be stated. 9.3.4. Premature termination or suspension of the study The clinical study can be prematurely terminated or suspended by the PI after reassessing the risks of the study. A premature termination may be necessary for the following reasons: * The incidence of Adverse Events constitutes a potential health hazard. * New scientific data on the investigational product do not justify a continuation of the clinical study. * Serious and/or persistent non-adherence to the protocol, GCP and/or applicable regulatory requirements by an investigator/institution. Furthermore, the PI has the right to terminate the study for any reason at any time. If the study is prematurely terminated or suspended, the investigator has to inform the patients and to assure appropriate follow-up for the patients. The PI should promptly inform the investigators/institutions and the regulatory authority(ies) of the termination or suspension and the reason(s) for them. The IRB/IEC should also be informed promptly and provided the reason(s) for the termination or suspension by the sponsor or by the investigator/institution, as specified by the applicable regulatory requirement(s). 9.4. TREATMENTS 9.4.1. Treatments administered The study drug Cerebrolysin will be administered as a single daily dose of 30 ml diluted with physiological saline to a total volume of 100 ml as an intravenous infusion over a time period of 30 min.. 9.4.2. Identity of the investigational product Intravenous Study Medication (Cerebrolysin or Placebo) The IV study medication is packaged in amber glass vials containing 100 ml ready-to-use infusion solution. This infusion solution will either contain 30 ml Cerebrolysin + 70 ml physiological saline (0.9% NaCl) or 100 ml physiological saline (0.9% NaCl) only according to the randomisation plan. Batch number and expiry date are documented in the Trial Master File. Study medication will be infused daily for 10 consecutive days, giving a total of 10 infusions. The first infusion shall start not later than 3 hours after completion of EVT (Visit 1B). Infusions will take place only at the clinical facility. For each patient, 10 plus 2 replacement vials of study medication will be provided. The 10 vials will packaged in a carton; the two replacement vials per patient will be packaged in two separate carton boxes with the appropriate labeling. Preparation of study medication The study medication is supplied as a ready-to-use product for Israel. No special preparation of the study medication is required there.. Sterile NaCl (70 ml) will be available in amber 100 ml glass vials. 30 ml Cerebrolysin (3 x 10 ml) or 3 x 10 ml Placebo will be added under aseptic conditions up to a final volume of 100 ml. In addition, supplies for the administration of the infusions including IV lines, butterfly needles, adhesive tapes and alcohol swabs will be provided. THE STUDY MEDICATION WILL BE LABELLED AS FOLLOWS: Intravenous Study Medication (Cerebrolysin) VIALS: BOXES AND OUTER CARTON: Other information will be included as per specific country requirements. The final label of the study medication will be defined country specific according to ICH-GCP as well as local requirements and will be filed in the investigator and trial master file. BOXES: REPLACEMENT VIALS 9.4.3. Method of assigning subjects to treatment groups Not needed everybody is receiving Cerebrolysin. 9.4.4. Selection of doses in the study The study will be conducted as a fixed-dose study in which one group of patients will receive 30 ml Cerebrolysin diluted with 70 ml physiological saline to a total volume of 100 ml. The other group will receive 100 ml of physiological saline as Placebo as a once daily infusion over a time period of 30 min. Start time and end of the infusion have to be recorded in the CRF. A dosage of 30 ml (OD) of Cerebrolysin is considered to be effective for the treatment of mild to moderately severe Alzheimer's Disease as shown in clinical studies and it has also shown efficacy in preliminary stroke trials. From previous experience it is suggested that this dosage should exert favourable clinical effects. This trial should also provide data on safety and tolerability of Cerebrolysin used immediately after thrombolytic therapy in patients suffering from acute ischemic stroke. Therefore the dosages should be maintained over the whole study period. All patients will receive a total of 10 infusions of study medication during the study on consecutive days. 9.4.5. Selection and timing of dose for each subject The study will be conducted as a fixed-dose study in which Cerebrolysin-treated patients will receive a once daily dosage of 30 ml of the study medication, diluted with 70 ml of physiological saline to a total volume of 100 ml as intravenous infusion over a time period of 30 minutes. Dosage adjustments are not permitted. Patients experiencing dose limiting Adverse Events must be withdrawn from the study. The first dosage will be applied immediately after the 1 hour rating which will be done after the end of the EVT therapy. Regardless the exact time of the first application, the next infusion of the study medication should be done on the next morning, between 07:00 and 10:00 a.m. All other treatments should be applied at approximately the same time of day within a time window of +/-2 hours. 9.4.6. Administration of study medication A butterfly needle will be inserted in a peripheral vein. Active treatment or Placebo will be infused intravenously over a period of approximately 30 minutes. The time of infusion will be recorded. The infusion will take place at approximately the same time every day within a time window of +/-2 hours. The infusion will only be administered, if the patient does have vital sign values within the following ranges: Supine BP systolic \<200 mm Hg Diastolic \<110 mm Hg Heart Rate 45-110/min. Body Temperature \<38.0°C Respiratory Rate 10-30/min. If one of the parameters is above the upper or below the lower limit, the nurse should wait for a few minutes and recheck the parameter. If the second measurement is within the limits, the infusion can be administered. Vital signs will be rechecked and recorded at the conclusion of the infusion. If a patient misses an infusion it may be added at the end of the treatment period to give a total of 10 infusions for that patient. A patient should not miss more than one consecutive infusion during the whole treatment period. 9.4.7. Blinding Not needed all patients are receiving Cerebrolysin. Blind will only exist in term of results of Post-EVT CTP results. 9.4.8. Prior and concomitant therapy Additional thrombolytic medication (e.g. urokinase or streptokinase) is forbidden. Brain protective drugs (e.g. brain specific calcium channel blockers or nootropics) are prohibited during the whole study period. Other drug therapy may be given according to patient needs. Osmotic agents (mannitol, glycerol) may be given, if the intracranial pressure is increased. Medication administered 48 hours prior to entry into the study must be recorded on the appropriate CRF page. All concomitant medication must be recorded (date of onset, highest total daily dose, stop date and route of administration). If usage is prophylactic, this must be indicated on the respective CRF page. 9.4.9. Treatment compliance and drug accountability The study medication (Cerebrolysin/Placebo) will be administered as single daily IV-infusion by the investigator or Coinvestigator for 10 consecutive days, starting not later than 3 hours after completion of EVT and after post EVT CT-Perfusion imaging. Compliance issues therefore do not play a role. Drug supplies, which will be provided by the PI, must be kept in a secure, limited access storage area under the storage conditions defined by the sponsor. Where necessary, a temperature log must be maintained to ensure that the drug supplies are stored at the correct temperature. The investigator and/or pharmacist must maintain records of the product's delivery to the trial site, the inventory at the site, the use by each subject and the return to the sponsor or alternative disposition of unused products. These records will include dates, quantities, batch/serial numbers, expiry dates (if applicable) and the unique code numbers assigned to the investigational products and trial subjects. Investigators will maintain records that document adequately that the subjects were provided the doses specified by the protocol and reconcile all investigational products received from the sponsor. A drug supply inspection for inventory purposes and to ensure proper storage will be conducted at regular intervals throughout the study. 9.5. EFFICACY AND SAFETY VARIABLES 9.5.1. Efficacy and safety measurements assessed and flow chart A patient may be enrolled into the study after giving his/her informed consent (or deferred in exceptional circumstances, according to national regulatory and legal requirements) when entering the clinic with acute stroke symptoms and after successful EVT treatment. All inclusion and exclusion criteria have to be checked prior to administration of the test dose of study medication. The visit 1 is divided into three sub-visits. Five visits will be conducted during the study. At visit 1A (baseline) the documentation of demographics, medical history, clinical lab, physical examination, vital signs, resting 12-lead ECG, concomitant therapy, NIH Stroke Scale at admission to hospital, modified Rankin Scale prior to ischemic stroke event, documentation of Adverse Events, pregnancy test (if appropriate).

The last examination takes place at 9 motnh ±7 days. BP/HR: For assessing safety, blood pressure and heart rate are to be measured supine at baseline (prior to administration of trial medication). Further BP/HR monitoring will take place in the following order: every 15 minutes until Hour 2 (i.e. after 15, 30, 45, 60, 75, 90, 105, 120 minutes starting the infusion of Alteplase), every 30 minutes until Hour 6 (i.e. 150, 180, 210, 240, 270, 300, 330, 360 minutes) and every hour until Hour 24. Thereafter up to Day 10 BP and HR have to be recorded twice daily, before and after each Cerebrolysin-infusion (supine after 5 minutes rest). ECG: Resting 12 lead-ECG readings are to be taken at baseline and on Day 10. Adverse Events (AE): AEs (free reporting by the patient after having been asked by the physician every day during the hospital stay) will be documented until hospital discharge (date and time of onset, date of last occurrence, intensity, etc.). From hospital discharge up to Day 90 only serious AEs will be reported. Efficacy parameters: The NIH Stroke Scale will be performed at baseline and 1 hour (after Drug administration), 2 hours (after), 24 hours (after), Day 5, Day 10 and Day 7/discharge, 30, 90 and 9 month.

Diagnostic variables NA 9.5.2. Appropriateness of measurements Cerebrolysin has already shown efficacy in smaller studies using the same or at least similar rating scales. The rating scales used in the study reflect state of the art as also applied in many other drug studies in stroke. The scales are relevant to document the neurological status of the patient at any given time point of the trial. The selection was also supported by the fact that these scales have been used for the thrombolytic studies as well, so a direct comparison to the results of these studies will be possible, to get additional information about a possible benefit of the adjuvant therapy with Cerebrolysin on outcome of patients suffering from acute ischemic stroke. 9.5.3. Efficacy variables 9.5.3.1. Primary efficacy variable(s) Modified Rankin Scale: a complete description of the scale is given in Appendix 11.4. 9.5.3.2. Secondary efficacy variable(s) A description of the NIH Stroke Scale is given in Appendix 11.1. Descriptions of MoCA, GDS and SF36 are given in Appendices 11.5., 11.6. and 11.7, respectively.
