Efficacy of a <i>Coriolus</i><i>versicolor</i>-Based Vaginal Gel in Human Papillomavirus-Positive Women Older Than 40 Years: A Sub-Analysis of PALOMA Study

Abstract

In the PALOMA trial, Papilocare® demonstrated efficacy in repairing low-grade cervical lesions related to human papillomavirus (HPV). This sub-analysis aimed to evaluate its efficacy in repairing these cervical lesions and clearing HPV in women aged older than 40 years. This was a multicenter, randomized, open-label, parallel-group, controlled clinical trial. Patients with low-degree HPV-dependent cervical lesions receiving 6-month treatment with the vaginal gel were compared to those with a watchful waiting approach. Among the 41 women analyzed (aged 47.7 years), 31 presented high-risk (HR) oncogenic HPV subtypes, and 14 had 16-18-31 HPV genotypes. After 6 months, normalized cytology and concordant colposcopy were achieved by a greater percentage of treated women. The difference was significant in the total population (92.3% vs. 50.0%, p = 0.007), and HR-HPV subpopulation (90.5% vs. 33.3%, p = 0.003). In the HR HPVs-16-18-31 subpopulation, the values were 75.0% and 40.0% (p = 0.293). In the total population, 61.5% of treated patients obtained HPV clearance, compared to 50.0% in the control group. Regarding the HR-HPV subpopulation, these values were 66.7% and 44.4%, respectively. Papilocare® demonstrated significant efficacy in repairing low-degree HPV-related cervical lesions and a positive trend to clear HPV in women older than 40 years old in comparison to the watchful waiting approach.
