A Study of NCS-01 in Patients With Acute Ischemic Stroke

This is an initial Phase1/2 dose-finding, randomized, multi-center study to evaluate the safety and tolerability of NCS-01 in patients with acute ischemic stroke. All patients will be randomized within 48 hours of stroke onset. This study will be conducted in 2 stages.

Inclusion criteria

  • Males and females, age 18 to 85 years inclusive
  • Clinical evidence of acute ischemic unilateral cerebral infarction
  • - Evidence of neurologic deficits as defined by NIHSS 6 to 18 or NIHSS < 6 with Fugl-Meyer upper extremity subtotal 6 to 40 inclusive
  • Women of child bearing potential who agrees to take acceptable birth control as described in the ICF
  • Provide written informed consent before participation, either by patient or a legal representative

Exclusion criteria

  • An inability to undergo an MRI scan
  • Any malignancies within the last 5 years
  • Previous organ transplantation
  • Participation in another clinical trial with an investigational drug, device or biologic within the preceding 3 months
  • Women of childbearing potential with a positive pregnancy test
  • Already dependent in activities of daily living (Rankin scale 3 or more) before the present acute stroke
  • Known hypersensitivity, allergy or intolerance to the similar biologic interventions
  • Any other clinically relevant acute or chronic diseases which could interfere with patients' safety during the trial, or expose them to undue risk, or which could interfere with study objectives judged by Investigator based on medical history, physical examination, laboratory tests and/or ECG

Treatment and study plan

NCS-01

Biological

single infusion

Primary outcomes

  1. Number of participants with adverse events -Safety by Incidence of Treatment-Emergent Adverse Events

    Time frame: multiple times for the duration of the study (baseline through Month 12)

    Number of participants with treatment-related adverse events as assessed by CTCAE v4.0" . Incidence and nature of adverse events; vital signs;

  2. National Institutes of Health Stroke Scale (NIHSS)

    Time frame: 1 hour, 3 hours, and 6 hours post infusion

    Change from baseline in the NIHSS NIHSS is a systematic assessment tool that provides a quantitative measure of stroke-related neurologic deficit. The score for each ability is a number between 0 and 4, 0 being normal functioning and 4 being completely impaired. The patient's NIHSS score is calculated by adding the number for each element of the scale; 42 is the highest score possible. In the NIHSS, the higher the score, the more impaired a stroke patient is.

  3. Number of participants with change in in physical examination

    Time frame: multiple times from baseline through Month 12

    physical examination changes General appearance ,Head, eyes, ears, nose, and throat, Respiratory, Cardiovascular, Musculoskeletal, Abdomen, Neurologic, Extremities, Dermatologic, Lymphatic)

  4. Number of participants with change in Electrocardiography (ECG)

    Time frame: multiple times for the duration of the study (baseline through Month 12)

    ECG (standard digital 12-lead in singlicate)

  5. Number of participants with change in clinical laboratory evaluations

    Time frame: multiple times for the duration of the study (baseline through Month 12)

    changes in clinical laboratory evaluations (Creatinine, Potassium(K+),Sodium (Na+) , Chloride (Cl-), Magnesium (Mg++), Calcium, Inorganic phosphate, Glucose, Urea,Bilirubin (Total) ,Bilirubin (direct), AST, ALT, GGT, Alkaline phosphatase, Total Protein Albumin,

Secondary outcomes

  1. Number of participants with change in Modified Rankin Scale (mRS)

    Time frame: multiple times for the duration of the study (baseline through Month 12)

    The modified Rankin Scale (mRS) is a commonly used scale for measuring the degree of disability or dependence in the daily activities of people who have suffered a stroke.Score Description 0 No symptoms at all

    • No significant disability despite symptoms; able to carry out all usual duties and activities
    • Slight disability; unable to carry out all previous activities, but able to look after own affairs without assistance
    • Moderate disability; requiring some help, but able to walk without assistance
    • Moderately severe disability; unable to walk without assistance and unable to attend to own bodily needs without assistance
    • Severe disability; bedridden, incontinent and requiring constant nursing care and attention
    • Dead

  2. Number of participants with change in Cytokine panel (IL-1, 6, 8, etc.)

    Time frame: multiple times for the duration of the study (baseline through Month 12)

    blood test for proteins that modulate the inflammatory response

  3. Number of participants with change in MRI

    Time frame: multiple times for the duration of the study (baseline through Month 12)

    global white matter and grey matter volumetrics; cortical thinning on MRI

  4. Number of participants with change in Barthel Index

    Time frame: multiple times for the duration of the study (baseline through Month 12)

    Barthel Index is a 4 point scale of Activities of Daily Living

Other outcomes

  1. Number of participants with change in Domain-specific Scales (Fugl-Meyer)

    Time frame: multiple times for the duration of the study (baseline through Month 12)

    The Fugl-Meyer Assessment (FMA) is a stroke-specific, performance-based impairment index. It is designed to assess motor functioning, sensation, balance, joint range of motion and joint pain in patients with post-stroke hemiplegia (Fugl-Meyer, Jaasko, Leyman, Olsson, & Steglind, 1975; Gladstone, Danells, & Black, 2002). It is applied clinically and in research to determine disease severity, describe motor recovery, and to plan and assess treatment.
