Vvax001 is safe and feasible and shows preliminary clinical effectiveness in patients with HPV16-associated CIN3 lesions.
In this study, we investigated the clinical efficacy of Vvax001 in patients with HPV16-positive cervical intraepithelial neoplasia (CIN) grade 3 (CIN3). A total of 18 patients were enrolled and fully immunized. Colposcopic examination revealed a reduction in CIN3 lesion sizes in 17/18 (94%) patients already evident from 3 weeks onward after the last immunization. A histopathologic complete response (regression to CIN grade 1 or no dysplasia) was observed in 9/18 patients (50%) at 6 months and HPV16 clearance in 10/16 patients (63%). Vvax001 did not induce clearance of other HPV types. To date, no recurrences have been observed, with a median and longest disease-free survival of 20 and 30 months, respectively. No serious adverse events were observed. |
