Main objective

Scope: Safety, Efficacy, Pharmacokinetic

To evaluate the safety of the investigational treatment compared to best medical therapy (BMT), on hemorrhagic transformation.

Secondary objectives 10

  1. To evaluate the impact of the investigational treatment compared to BMT on the degree of disability in patients with stroke
  2. To evaluate the impact of the investigational treatment, compared to BMT, on the final infarct volume.
  3. To evaluate the impact of the investigational treatment, compared to BMT on recanalization of the occluded vessel
  4. To assess the impact of the investigational treatment, compared to BMT, on the impairment caused by the stroke as assessed by various aspects of brain function
  5. To evaluate the safety and tolerability of study intervention
  6. To assess the impact of the investigational treatment, compared to BMT, on all-cause mortality
  7. To assess the impact of the investigational treatment on the development of depression following the stroke
  8. To assess the impact of the investigational treatment compared to BMT, on the levels of selected biomarkers
  9. To assess plasma levels of the investigational combination treatments
  10. To evaluate the correlation between the plasma concentrations of investigational combination treatments with the safety, response, and compliance to treatment

  5. A maximum of 36 h may elapse from symptoms’ onset to treatment initiation.
  6. Pre-stroke (36 hours prior to stroke onset) independent functional status in activities of daily living (ie, patients must have been living without requiring nursing care) based on information provided by the patient or his/her caregivers.
  7. Patient not a candidate for thrombolysis with tPA.
  8. Patient not a candidate for thrombectomy.
  9. A diabetic patient must have been on a stable antidiabetic regimen at least 8 weeks before inclusion in the study.
  10. Patient with either no history of depression or treated for depression with a stable combination of antidepressants for at least 8weeks before inclusion in the study.
  11. Patient with no known history of dementia.
  12. Provision of signed informed consent by the patient or caregiver/legal representative, which includes compliance with the requirements and restrictions listed in the informed consent form (ICF) and in the protocol.
  13. Expectation that the patient will receive standard physical, occupational, and speech rehabilitation therapies as indicated for post-stroke deficits.
  14. Patient or caregivers understand study procedures and are willing to comply with them for the entire length of the study.

Exclusion criteria 17

  1. Allergy/sensitivity to study drugs or their ingredients.
  2. Current drug or alcohol use or dependence that, in the opinion of the site Investigator, would interfere with adherence to study requirements.
  3. Inability or unwillingness of patient or caregiver/legal guardian/representative to give written informed consent.
  4. Pregnancy or lactation, at screening.
  5. Patient who plans to become pregnant within 6 months, or women in childbearing age with negative pregnancy test but who refuses to accept contraception.

Total bilirubin >1.5xULN (Participants with Gilbert’s syndrome can be included with total bilirubin >1.5 x ULN as long as direct bilirubin is ≤1.5 x ULN) c. Current or chronic history of liver disease.
  13. Concurrent treatment with any of the investigational drugs in this study.

  17. Treatment with medications/agents which are contraindicated based on the SmPCs of the combination IMPs for usage in combination with the study interventions.

Endpoints

Primary and secondary outcome measures (English text)

Primary endpoints 1

  1. Percentage of patients with hemorrhagic transformation as depicted in a CT or MRI.

Secondary endpoints 10

  1. Degree of disability based on the mRS score
  2. • Infarct volume defined as MRI lesion volume on Day 5 • Infarct volume defined as MRI lesion volume on Day 90 • Change in DWI lesion volume from Day 5 to Day 90, based on MRI • Change in PWI lesion volume from Day 5 to Day 90, based on MRI
  3. Change in recanalization of the occluded vessel based on MR angiography (MRA).
  4. Percentage of patients with clinically meaningful improvement in NIHSS score (improvement >4 points).
  5. • Percentage of patients treated with investigational combination therapy on top of BMT and those treated with BMT only, experiencing all-cause on-treatment AEs, analyzed for: o patients that complete the study period, and o patients who discontinue from the study period due to an AE. • Percentage of patients with abnormal clinically significant laboratory test results.
