Effect of a Multi-Ingredient Coriolus-versicolor-Based Vaginal Gel in Women with HPV-Dependent Cervical Lesions: The Papilobs Real-Life Prospective Study.

Human papillomavirus (HPV) is responsible for virtually all cervical cancers in women. HPV infection and persistency may lead to different-grade squamous intraepithelial lesions that can result in high-grade lesions and cancer. The objective was to prospectively evaluate the results of using a Coriolus-versicolor-based vaginal gel (Papilocare®) on HPV-dependent low-grade cervical lesion repair in a real-life scenario. HPV-positive women ≥ 25 years with ASCUS/LSIL cervical cytology results and concordant colposcopy images were included, receiving the vaginal gel one cannula/day for 21 days (first month) + one cannula/alternate days (five months). A 6-month second treatment cycle was prescribed when needed. Repair of the cervical low-grade lesions through cytology and colposcopy, HPV clearance, and level of satisfaction, and tolerability were evaluated. In total, 192 and 201 patients accounted for the total and safety analyses, respectively, and 77.1% repaired cervical lesions at 6 or 12 months (76.0% for high-risk HPV). Additionally, 71.6% achieved HPV clearance throughout the study's duration (70.6% for high-risk HPV). Satisfaction level was rated 7.9 and 7.5 out of 10 at 6 and 12 months, respectively. Only three mild-moderate product-related adverse events were reported, and all of them were resolved by the end of the study. In our study, we observed higher regression rates of low-grade cervical lesions in women treated with Papilocare® vaginal gel than spontaneous regression rates reported in the literature.

Efficacy of a Coriolusversicolor-Based Vaginal Gel in Human Papillomavirus-Positive Women Older Than 40 Years: A Sub-Analysis of PALOMA Study.

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.
