The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Outcomes
Primary outcome [1] 0 0
Proportion of participants with substantial reperfusion at final angiography (15 +/- 5min after final nanoparticle injection) without symptomatic intracranial hemorrhage on CT/MRI at 24h
Timepoint [1] 0 0
24 hours +/- 6 hours

Eligibility
Key inclusion criteria
* Patients presenting with ischemic stroke within 24 hours of the time they were last known to be well
* Patient's age is =18 years
* Legal requirements for consent as per local legislative requirements are satisfied.
* Distal medium vessel intracranial arterial occlusion visible on CT-angiography, MR-angiography or catheter digital subtraction angiography (DSA) in the middle cerebral, anterior or posterior cerebral artery. The occlusion may be primary or secondary (ie following initial mechanical thrombectomy of a large vessel occlusion)
Minimum age
18 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
* Intracranial hemorrhage (ICH) identified by CT or MRI
* Rapidly improving symptoms at the discretion of the investigator
* Pre-stroke mRS score of = 3 (indicating functional dependence)
* Frank hypodensity in >1/3 of the affected arterial territory on non-contrast CT
* CT Perfusion ischemic core volume > 100 ml
* Known automated implantable cardiac defibrillator, pacemaker, cerebral aneurysm clip, cochlear implant, cranial neurostimulator or other device implant that is incompatible with the external magnetic field
* Known allergy or sensitivity to iron
* Known hemochromatosis, or known liver disease such as cirrhosis.
* Known aortic dissection
* Suspected septic embolization
* Contra indication to imaging with contrast agents
* Pregnant or lactating women
* Any terminal illness such that patient would not be expected to survive more than 6 months
* Current participation in another investigational drug or device treatment study
* Any condition that, in the judgment of the investigator could impose hazards to the patient if study therapy is initiated or affect the participation of the patient in the study.
