First seen Jan 10, 2026 · Last updated May 14, 2026 · Updated 21 times

Summary

This study tests a gene therapy called Zopapogene imadenovec (Zopa) in adults with recurrent respiratory papillomatosis (RRP), a rare condition causing non-cancerous throat tumors that often come back after surgery. The study has two groups: one checks how the virus used in the therapy leaves the body, and the other sees if retreating with Zopa can prevent the need for surgery for a full year. About 30 participants will be enrolled to evaluate safety and effectiveness.
