Papilozumib Vaginal Gel for Exocervical Mucosal Restoration in Women With Human Papillomavirus (HPV)

Condition(s) studied

Investigational drug(s) / intervention(s)

Papilozumib vaginal gel: Papilozumib® is a single-dose vaginal gel administered for 6 months. During the first 3 months, participants apply one vaginal applicator daily for 21 days followed by 7 days without treatment. During the following 3 months, participants apply one applicator on alternate days, excluding menstrual periods.

Papilozumib oral supplement: Papilozumib® oral supplement is provided as capsules containing mushroom extracts, vitamins, minerals, and probiotics. Participants take three capsules daily for 6 months: two capsules while fasting and one capsule before dinner, separated from meals.

Study summary

This randomized, open-label, multicenter clinical study is designed to evaluate Papilozumib® vaginal gel in women aged 30 to 50 years who test positive for human papillomavirus (HPV) and present with either normal cervical cytology or cytological findings of atypical squamous cells of undetermined significance (ASC-US), low-grade squamous intraepithelial lesion (LSIL), or atypical glandular cells (AGC), accompanied by corresponding colposcopic findings.

Eighty-one participants will be randomly assigned in equal groups to receive either Papilozumib® vaginal gel, Papilozumib® vaginal gel plus an oral supplement, or standard clinical care without study treatment. All participants will be followed for six months.

The primary objective is to assess exocervical mucosa restoration 30 days after treatment initiation using a 5-point colposcopic scale. Additional assessments include cervical cytology, HPV clearance, vaginal health, treatment adherence, satisfaction, tolerability, safety, and exploratory analyses of the vaginal and intestinal microbiota.

Eligibility

Primary outcome measure(s)

• Exocervical mucosal restoration score at Day 30 — Day 30 after treatment initiation
  Exocervical mucosal restoration will be assessed by colposcopy in participants assigned to Papilozumib® vaginal gel alone. The investigator will score the exocervical mucosa using a 5-point scale: 1, severe ectopia with bleeding; 2, severe or extensive ectopia involving more than 50% from the external cervical opening; 3, moderate ectopia involving 25% to 50%; 4, mild ectopia involving less than 25%; and 5, no ectopia. Higher scores indicate greater exocervical mucosal restoration.
• Participants with concordant cytology and colposcopy at Day 30 — Day 30 after treatment initiation
  In participants assigned to Papilozumib® vaginal gel alone, the investigator will record whether the cervical cytology result is concordant with the colposcopic finding using a "Yes" or "No" response. The outcome will be reported as the percentage of participants with concordant findings.
