A Safety Evaluation of the Use of Magnetic-guided Iron Particles
A Safety Evaluation of the Use of Magnetic-guided Iron Particles
This study is a prospective trial wherein each included subject will receive the experimental
 magnetically enhanced diffusion therapy. It will be conducted on a maximum of ten adult male
 or female patients who meet the inclusion and exclusion criteria and informed consent has
 been obtained. Subjects presenting in the emergency department with acute ischemic stroke and
 are eligible for tPA therapy may be considered for inclusion in the study.
This study is a prospective trial wherein each included subject will receive the experimental
 magnetically enhanced diffusion therapy. It will be conducted on a maximum of ten adult male
 or female patients who meet the inclusion and exclusion criteria and informed consent has
 been obtained. Subjects presenting in the emergency department with acute ischemic stroke and
 are eligible for tPA therapy may be considered for inclusion in the study.

 Subjects who meet the eligibility criteria will be treated with Magnetically Enhanced
 Diffusion (MED) concurrently with tPA infusion. Perfusion will be assessed using CTA/CTP at
 2-4 hours upon completion of tPA infusion and using MRI at 24 hours upon completion of tPA
 infusion. Subjects are followed at 14 days, 30 days and 90 days post-treatment.
Inclusion Criteria:

 -  Subject is between 18 and 80 years of age.

 -  Subject has moderate to large (NIHSS ≥ 10 and ≤24) ischemic stroke

 -  Subject has an intracranial arterial occlusion of the middle cerebral artery (MCA),
 anterior cerebral artery (ACA), internal carotid artery (ICA), posterior cerebral
 artery (PCA) or distal basilar artery confirmed by CT or MR angiography.

 -  Subject is eligible for initiation of intravenous tPA within three hours of stroke
 onset, where time of stroke onset is defined as the last time the patient was
 witnessed to be at baseline.

 Exclusion Criteria:

 -  Subject has known sensitivity to iron or PEG products.

 -  Subject has recently (within 30 days) received iron replacement therapy.

 -  Subject has known or suspect liver function abnormality.

 -  Subject has known or suspect severe renal impairment.

 -  Subject has a high-density lesion on baseline CT scan consistent with hemorrhage of
 any degree.

 -  Subject has a significant mass on baseline CT consistent with midline shift.

 -  Subject has a large (greater than one-third of the middle cerebral artery) regions of
 clear hypodensity on the baseline CT scan.

 -  Subject has evidence of intraparenchymal tumor on baseline CT scan.

 -  Subject experiences a seizure at the onset of stroke.

 -  Subject has known hemosiderosis or hemochromatosis.

 -  Subject has an implantable cardioverter defibrillator, pacemaker, neurostimulator or
 other device incompatible with MRI.

 -  Subject has a history of stroke within the last three months.

 -  Subject has a previous or existing intracranial hemorrhage, neoplasm, subarachnoid
 hemorrhage or arteriovenous malformation.

 -  Subject has experienced any active or recent (within 30 days) hemorrhage.

 -  Subject has systolic blood pressure > 185 mmHg or diastolic > 110 mmHg.

 -  Subject has presumed septic embolus or suspicion of bacterial endocarditis.

 -  Subject has presumed pericarditis including pericarditis after acute myocardial
 infarction.

 -  Subject is suspected to have an aortic dissection.

 -  Subject has recently (within 30 days) undergone surgery or biopsy of a parenchymal
 organ.

 -  Subject has recently (within 30 days) experienced trauma with internal injuries or
 ulcerative wounds.

 -  Subject has recently (within 90 days) experienced severe head trauma with loss of
 consciousness.

 -  Subject has known hereditary or acquired hemorrhage diathesis, coagulation factor
 deficiency, or oral anticoagulant therapy with INR > 1.7 or institutionally equivalent
 prothrombin time.

 -  Subject has a glucose level of < 50 mg/dl or >400 mg/dl, or a platelet count less than
 100,000, or an Hct level less than 25.

 -  Subject has taken dabigatran within the last 48 hours or any new anticoagulant which
 cannot be monitored by traditional.

 -  Subject requires hemodialysis or peritoneal dialysis, or has a contraindication to
 angiogram.

 -  Subject has prolonged partial thromboplastin time (PTT) (in the case where heparin or
 a direct thrombin inhibitor has been administered within 48 hours).

 -  Subject has had a recent (within 7 days) lumbar puncture or arterial puncture at a
 non-compressible site.

 -  Subject has a pre-existing neurological or psychiatric disease that would confound
 evaluations.

 -  Subject is pregnant, nursing or intends to become pregnant during the trial period.

 -  Subject is currently enrolled in other potentially confounding research.

 -  Subject has any condition that, at the discretion of the investigator, would preclude
 participation in the trial.
