Detailed Description

This patient funded trial aims to study the safety and efficacy of cultured allogeneic adult umbilical cord derived mesenchymal stem cell (UC-MSCs) exosomes for the treatment of Trigeminal Neuralgia. Patients will receive an intranasal instillation of UC-MSCs exosomes. The total dose will be approximately 800 billion exosomes split evenly between both nasal cavities via Tian Syringe through 4 CCs of AlloEx. 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.
