Identifying immune responses in women treated with imiquimod for cervical lesions

Immunophenotyping, Microbiome, Clinical Outcome and Biomarkers for Predicting Immunological Response in Patients with High-grade Cervical Intraepithelial Lesions Treated with Imiquimod

Phase 4 Interventional Barretos Cancer Hospital · NCT06356012

This study is testing how well the immune system responds to a cream called imiquimod in women with high-grade cervical lesions compared to those getting standard treatment or who have no lesions.

What this trial studies

This clinical trial aims to characterize the immune response and microbiological profile in women diagnosed with high-grade cervical intraepithelial lesions (CIN 3) treated with imiquimod. Participants will be divided into three groups: those receiving imiquimod treatment, those undergoing standard excisional treatment, and those with negative cytology and HPV. Blood and cervicovaginal samples will be collected at various points to analyze the immune response to treatment. The study seeks to improve understanding of how imiquimod works and its effects on patients.

Who should consider this trial

Good fit: Ideal candidates are women aged 25 to 45 with a histological diagnosis of CIN 3 and high-risk HPV.

Not a fit: Patients with invasive cervical cancer, those who are pregnant or breastfeeding, or those with immunodeficiency conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more personalized and effective treatments for women with high-grade cervical lesions.

How similar studies have performed: Previous studies have shown the efficacy of imiquimod in treating CIN lesions, indicating potential for success in this approach.
