A Phase II, Randomized, Double-Blind, Placebo-Controlled Study to Evaluate the Safety and Efficacy of Azficel-T for the Treatment of Vocal Fold Scarring and Age-Related Dysphonia
In Brief
A Phase 2 clinical trial evaluating Azficel-T (autologous fibroblasts) and Placebo for Dysphonia Resulting From Vocal Fold Scarring and Age-related Dysphonia. Completed, enrolled 21 participants across 3 sites.
Detailed Summary
The objectives of this study are to assess the safety of azficel-T treatment for dysphonia related to vocal fold function and to evaluate the efficacy of azficel-T for the treatment of dysphonia related to vocal fold function.
Study Details
Timeline
Interventions
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).
