Clinical Utility and Safety of Human Umbilical Cord Mesenchymal Stem Cell Secretome in Drug Resistant Epilepsy Single Center, Non-randomized, Phase I Clinical Trial

The goal of this clinical trial is to learn if Human Umbilical Cord Mesenchymal Stem Cell (HUCMSC) derived secretome injection is safe and effective in patient with epilepsy. The main questions it ams to answer are: 1. How is the relationship between secretome therapy and the reduction in seizure frequency and duration in patients with drug-resistant epilepsy in the adult age group? 2. How does secretome therapy affect EEG and qEEG results in patients with drug-resistant epilepsy in the adult age group? 3. How is the relationship between secretome therapy and the Mini Mental State Examination (MMSE) score in patients with drug-resistant epilepsy in the adult age group? 4. How does secretome therapy affect stress levels as measured by the Perceived Stress Scale (PSS) in patients with drug-resistant epilepsy in the adult age group? 5. How does secretome therapy affect Gait Deviation Index (GDI) scores in patients with drug-resistant epilepsy in the adult age group? 6. How does secretome therapy affect quality of life as measured by the Quality of Life in Epilepsy Inventory (QOLIE-31) in patients with drug-resistant epilepsy in the adult age group?
