Phase II Study of Dysplasix™ Intravaginal Suppositories in Patients Patients With High-Risk HPV and Mild Cervical Cytologic Abnormalities
A Phase II, Randomized, Double-blind, Placebo-Controlled, Proof of Concept Study to Assess the Safety and Efficacy of Dysplasix™ Intravaginally-Administered Suppositories in Patients With High-Risk Human Papillomavirus (Hr-HPV) as Determined by HPV Testing, and Accompanied by Either (1) Atypical Squamous Cells of Undetermined Significance (ASC-US) or (2) Low-Grade Squamous Intraepithelial Lesions (LSIL), as Determined by Cytology
The goal of this clinical trial is to learn if an investigational vaginal suppository therapy works to treat low-grade cervical lesions (ASC-US and LSIL) associated with high-risk human papillomavirus (hr-HPV) infection in women. It will also learn about the safety and tolerability of this investigational therapy. The main questions it aims to answer are:
- Does the investigational therapy lead to regression of cervical lesions?
- Does the investigational therapy help clear hr-HPV infection?
- Do any adverse effects occur from using this medical product?
Researchers will compare the investigational therapy to a placebo (a look-alike substance that contains no active drug) to see if the investigational therapy works.
Participants will:
- Be screened for hr-HPV, cervical abnormalities, and other conditions to be assessed for eligibility
- Self-administer 15 doses of the investigational therapy or placebo as a vaginal suppository over 19 calendar days
- Attend scheduled clinic visits for examinations, testing, and monitoring for a period of two months
- Undergo assessments to evaluate cervical lesion status, hr-HPV infection, and safety outcomes
- Keep a daily diary of investigational therapy use and associated information

Yksityiskohtainen kuvaus
AMP.2025.001 is a Phase II, Double-Blind, randomized, Placebo-Controlled, Proof-of-Concept study to assess the safety and efficacy of Dysplasix™ Intravaginal Suppositories in females with hr-HPV and one of the following: cytologically confirmed (1) Atypical Squamous Cells of Undetermined Significance (ASC-US) or (2) Low-Grade Squamous Intraepithelial Lesions (LSIL)
Participants must undergo both (1) HPV testing and (2) a liquid-based exfoliative cytology test.
If, at laboratory screening, high-risk HPV and either (1) ASC-US or (2) LSIL cytologic abnormalities are detected, participants will be eligible for inclusion. If high-grade SIL (HSIL) or glandular abnormalities (AGC-NOS, AGC-N, AIS) are detected, participants will be excluded.
Eligible participants with high-risk HPV and either (1) ASC-US or (2) LSIL cytology will be randomized in a 1:1 ratio to Dysplasix™ or a matching Placebo until participants who meet eligibility are enrolled. Suppositories (Dysplasix™) or placebo will be intravaginally self-administered once nightly for a fifteen (15) day course of therapy (3 cycles of 5 days followed by two days off between cycles) applied at night immediately before sleep, beginning shortly after the end of menses. Tolerability of the drug will be recorded in daily participant diaries and assessed at regularly scheduled clinical assessment visits.
Participants will undergo complete cervical screening, including hr-HPV testing and cytology 30 (+/- 14) days after completion of treatment in addition to adverse events assessments.
Adverse events are evaluated using Common Terminology Criteria for Adverse Events v5.0.
