First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study tests a gene therapy called Zopapogene imadenovec (Zopa) in 30 adults with recurrent respiratory papillomatosis (RRP), a condition causing non-cancerous throat tumors that often require repeated surgeries. One group will check how the virus used in the therapy leaves the body, while another group will see if retreatment can eliminate the need for surgery for a full year. The goal is to control the disease and reduce the burden of frequent procedures.
