Magnesium And Verapamil After Recanalization in Ischemia of the Cerebrum: a Clinical and Translational Study.

NCT02912663 | Completed Phase 1 DMC FDA Drug

• 1 other identifier: Verapamil & magnisium sulfate
• Study Type: interventional
• Target: 10
• Locations: 1 country
• Sites: 1

Brief Summary

This is a phase 1, blinded-outcome, randomized, placebo controlled study to investigate the safety and feasibility of super-selective intra-arterial administration of verapamil and magnesium sulfate immediately following successful endovascular thrombectomy as a potential neuroprotective synergistic therapeutic strategy in emergent large vessel occlusion stroke. This trial represents the first time that magnesium sulfate will be evaluated in human subjects as a superselectively administered neuroprotective agent administered in an acute time frame as an adjunct to intra-arterial thrombectomy. Furthermore, it will represent the first trial to evaluate combinational therapy for acute stroke neuroprotection.

Conditions

Ischemic Stroke

Outcome Measures

Primary Outcomes (1)

• Number of participants having no symptomatic intracranial hemorrhage

  Defined as a hemorrhage occurring within 48 hours after study inclusion, temporally related to the intervention, and occurring with worsening neurological status as documented in the clinical exam.

  within 48 hours after treatment

Secondary Outcomes (1)

• Number of participants who had no systemic side effects from verapamil and magnesium sulfate

  within 90 days

Study Arms (2)

Verapamil and Magnesium Sulfate

EXPERIMENTAL

10mg of verapamil in 10 cc of normal saline and 1000mg of magnesium sulfate in 20cc of normal saline will be administered over 20 minutes (1cc/minute) through the microcatheter and into the vessel previously obstructed by clot to the treatment group

Drug: Verapamil and Magnesium Sulfate

Eligibility Criteria

• Age: 18 Years - 101 Years
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Signed and dated informed consent and HIPAA form. Participants with impaired capacity may be included provided a Legally Authorized Representative as recognized by the the State of Kentucky, signs the informed consent.
• Willingness to comply with all study procedures and availability for the duration of the study.
• Male or female, aged 18 years or older
• Suspected acute ischemic stroke based on clinical and radiographic evidence as determined and documented by the Stroke Neurology team at University of Kentucky.
• Participants must meet criteria for intra-arterial thrombectomy as determined and documented by Interventional Neuroradiology attending physician at University of Kentucky.
• Participants must have an acute thromboembolus within an intracranial artery in the anterior circulation (internal carotid, anterior cerebral, middle cerebral), which undergoes mechanical thrombectomy.
• Participant must have a TICI 2B or better revascularization via thrombectomy.
• For females of reproductive potential a negative pregnancy test at baseline is required.

You may not qualify if:

• Pregnant/lactating women
• Therapeutic anticoagulation prior to admission as it is a relative contraindication to thrombectomy
• Participants who undergo intra-arterial thrombectomy for acute stroke, in whom only TICI 0-2A revascularization is obtained.
• Known allergic reactions to components of Verapamil or magnesium sulfate.
• Verapamil should not be given to individuals who have a serious heart condition such as:
• sick sinus syndrome or AV block
• severe heart failure;
• fainting do to slow heartbeats
• certain heart rhythm disorders of the atrium (excluding atrial fibrillation)
• active congestive heart failure;
• low blood pressure;
• a nerve-muscle disorder such as myasthenia gravis or muscular dystrophy.
• Magnesium Sulfate should not be given to individuals with heart block or heart damage.
