Clinical Trial Summary

This is a prospective, 2-part, multi-center, open-label, non-randomized clinical trial to assess safety and effectiveness of APrevent® VOIS Implants for the treatment of patients with Unilateral Vocal Fold Paralysis (UVFP). In total 30 evaluable patients are planned to be enrolled.


Clinical Trial Description

The APrevent® VOIS is intended to be permanently implanted during a type I thyroplasty in individuals suffering from permanent unilateral vocal fold paralysis of various etiologies. Four post-operative follow-up visits are planned: Week 1 (± 7 days), Week 7 (-7/+28 days), Month 6 (-14/+28 days) and Month 12 (-14/+28 days). This 2-part study will consist of Part A to assess safety of the patients and the following Part B to assess the performance (effectiveness) of the investigational device. In Part A of the study 8 patients will be enrolled sequentially within three groups (N=1, N=2, N=5). After enrolment and 1st Follow-up Visit of each group, a Local Safety Board will review safety and study data. No preliminary/interim analysis of safety and effectiveness data will be performed before the end of the study. ;
