New vaccine aims to reverse HPV-Linked cervical changes without surgery

NCT ID NCT07454915

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

Summary

This phase 2 trial tests a DNA vaccine called PVX4 in 138 women with HPV16-related high-grade cervical dysplasia (CIN2/3). The vaccine is given as a shot with a small electrical pulse to help it enter cells. The goal is to see if it can clear the virus and make abnormal cervical tissue return to normal within 6 months, potentially avoiding the need for surgery.
