Clinical Trial Summary

The investigators propose to infuse healthy autologous mitochondria into cerebral vessels supplying brain tissue experiencing ischemia in patients who undergo standard-of- care endovascular reperfusion therapy.

Description:

Stroke is one of the leading causes of morbidity and mortality worldwide. More than 80% of strokes are the result of ischemia caused by blockage of one or more cerebral arteries. Lack of blood supply starves brain cells of necessary glucose and oxygen, and disturbs cellular homeostasis, eventually resulting in neuronal death.

Mitochondria are tiny organelles present in nearly all types of human cells and are vital to our survival. Much like a battery, they generate most of our adenosine triphosphate (ATP), the energy currency of the cell. Mitochondria are also involved in other tasks, such as signaling between cells and cell death. All these functions can be impaired during ischemia because of the damage caused to mitochondria.

Based on many preclinical studies in animals, damage caused by ischemia can be reversed after infusing healthy mitochondria into injured tissues. An ongoing clinical trial in human hearts at Boston Children's Hospital has also demonstrated that transplanting autologous mitochondria via infusion or direct injection is well-tolerated and safe.

The investigators at the University of Washington are recruiting subjects for a first-in-human-brain trial to confirm the safety of autologous mitochondrial transplant during brain ischemia. The transplantation will be performed within the same procedure as the clinically indicated reperfusion treatment.

During standard-of-care endovascular treatment for cerebral ischemia, the investigators will obtain a very small biopsy from the muscle tissue adjacent to our surgical access site. Muscle tissue will be processed at bedside to extract the autologous mitochondria as performed in prior human cardiac trial and validated in animal studies. The endovascular treatment proceeds without disruption as clinically indicated, and the mitochondria are infused into the brain artery via micro-catheter during reperfusion.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Incidence of severe adverse events during mitochondrial infusion	Cerebral angiography is performed and reviewed in real-time throughout the standard of care reperfusion treatment, including before and after microcatheter infusion of mitochondria.	Through completion of reperfusion therapy, up to one hour post-infusion
Primary	Incidence of severe adverse vascular events immediately post-mitochondrial infusion	Post-reperfusion therapy, CT scans are performed as part of the standard of care. The post-procedure CT scan will be reviewed for severe adverse events associated with the microcatheter infusion of mitochondria.	Up to 3 hours post-mitochondrial infusion
Primary	Incidence of severe systemic adverse events associated with mitochondrial infusion	Post-reperfusion therapy, peripheral blood studies are performed and reviewed as part of the standard of care to assess systemic function. These include complete blood counts, coagulation studies, and serum chemistry.	Up to seven days after procedure completion
Primary	Incidence of severe adverse events related to muscle biopsy	Muscle biopsy is obtained through the same incision as vascular access. The access site is evaluated via physical examination by medical personnel for six hours post-intervention per standard of care protocol.	Up to six hours after procedure completion
Secondary	Reduction of infarct volume post-mitochondrial infusion	Patients undergo brain MRI as part of standard of care evaluation after reperfusion therapy. These studies are compared with initial brain imaging studies obtained prior to reperfusion therapy.	Up to seven days after procedure completion.
