Brief Summary:
Evaluate the safety, tolerability, and preliminary efficacy of GD-iEXo-002 nasal drops in the treatment of focal refractory epilepsy
Detailed Description:
Epilepsy patients can achieve good control after treatment, but still 30% of patients are medically refractory epilepsy, with the vast majority being focal epilepsy. Recurrent seizures seriously affect the normal development, learning, and life of patients. There is an urgent need for effective drugs to treat refractory focal epilepsy in clinical practice.
Exosomes are a kind of vesicle structures secreted by cells, with a diameter of 30-150 nm, carrying proteins, nucleic acids and other substances. Exosomes have many advantages. As naturally occurring nanoscale secretory membrane vesicles, they have extremely low immunogenicity and good safety, and can cross biological barriers such as the blood-brain barrier and the blood-tumor barrier. Exosomes have specific bioactive substances related to source cells, while stem cell exosomes contain TGF- β、 Functional factors such as BDNF can inhibit cell apoptosis, inhibit inflammatory response, promote angiogenesis, inhibit fibrosis, and enhance tissue repair potential, with a wide range of potential applications.
Induced pluripotent stem cell (iPSC) originates from single cell amplification, with infinite proliferation ability, good consistency and stability; MSCs exhibit significant heterogeneity.
The purpose of this single center, open label clinical trial is to evaluate the safety, tolerability, and preliminary efficacy of induced pluripotent stem cell derived exosomes (iPSC-Exos) nasal drops in the treatment of focal refractory epilepsy.
