Controlled Study to Evaluate the Safety and Efficacy of Azficel-T for Vocal Fold Scarring and Age-Related Dysphonia

"Autologous fibroblasts will be cultured from three 3-mm post auricular punch biopsies. Biopsies will be shipped from the clinical sites to the Fibrocell manufacturing site where the cells will be harvested, tested for sterility, endotoxin level, cell identity, viability and concentration. When the desired cell number is reached, cells will be transported to the investigative site as a suspension in shipping media.~Depending upon the clinical circumstances for each subject, the vocal fold(s) will be injected transorally or percutaneously in order to deposit 1.0 mL of study drug into the lamina propria layer of each vocal fold. The injection process will be visualized via a flexible fiberoptic laryngoscope inserted through the nostril."

Subjects randomized to placebo will receive injections of sterile saline into the vocal fold(s).
