Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This trial will study the safety and efficacy of intranasal instillation of cultured allogeneic adult umbilical cord derived mesenchymal stem cell exosomes for the treatment of Stroke

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This patient funded trial aims to study the safety and efficacy of intranasal instillation of cultured allogeneic adult umbilical cord derived mesenchymal stem cell (UC-MSC) exosomes for the treatment of Stroke. Patients will receive intranasal instillations between both nasal cavities of UC-MSC exosomes. The total dose will be 4 CC of AlloEx, approximately 800 billion exosomes, for each day. Patients will receive instillations on back-to-back days totaling 2 doses. Patients will be evaluated within one month pre treatment and at 1, 6, 12, 24, 36, and 48 months post treatment for safety and efficacy.

For patients with more severe disease an autologous Effector cells (activated lymphocytes) treatment will be utilized created from the patient's own cells obtained by apheresis.
