Cancer vaccine for treating premalignant cervical lesions

A Phase II Study to Determine the Efficacy and Safety of Vvax001, a Therapeutic Semliki Forest Virus Based Cancer Vaccine, in Patients With HPV-16 Induced Grade 3 Cervical Intraepithelial Neoplasia

Phase 2 Interventional University Medical Center Groningen · NCT06015854

This study is testing a new cancer vaccine to see if it can help people with early-stage cervical lesions caused by HPV16 get better without needing surgery.

What this trial studies

This phase II study evaluates the efficacy of the Vvax001 cancer vaccine in patients with newly diagnosed HPV16-induced cervical intraepithelial neoplasia grade 3 (CIN3). Participants will receive three doses of the vaccine, administered three weeks apart, to stimulate an immune response aimed at regressing CIN3 lesions and clearing HPV. The effectiveness of the treatment will be monitored through colposcopy and biopsy at specified intervals to assess histopathological regression. If successful, patients may avoid standard surgical interventions typically required for CIN3.

Who should consider this trial

Good fit: Ideal candidates are women aged 18 and older with newly diagnosed HPV16-positive CIN3.

Not a fit: Patients with PAP5 lesions or those who have previously undergone treatment for CIN lesions may not benefit from this study.

Why it matters

Potential benefit: If successful, this vaccine could provide a non-surgical treatment option for patients with premalignant cervical lesions, reducing the risk of complications associated with surgery.

How similar studies have performed: Previous studies have shown promising results with similar immunotherapy approaches, indicating potential for success in this novel application.
