About this study

Official title: A Phase 2, Double-Blind, Placebo-Controlled Study to Determine the Dose Regimen, Efficacy, Safety, and Tolerability of VP-102 in Subjects With External Genital Warts

This is a Phase 2, double-blind, placebo-controlled study to determine the dose regimen, safety, tolerability, and efficacy of VP-102 in subjects with External Genital Warts (EGW). This study is divided into two parts (Part A and Part B). Increasing durations of skin exposure to study drug (VP-102 or placebo) will be evaluated in three treatment groups prior to progressing to enrollment in Part B. Part A \& B will enroll a approximately 108 subjects completing 4 treatment applications every 21 days and continuing with follow-up assessments at Day 84, 112 and 147.

Read the detailed description

This study is to determine the Dose Regimen, Efficacy, Safety, and Tolerability of VP-102 in Subjects with External Genital Warts. It is divided into two parts (Part A and Part B). The aim of Part A is to determine the two best treatment regimens for evaluation of safety and efficacy in Part B.In Part A, Study drug (VP-102 or placebo) will be administered once every 21 days for up to four applications. Enrollment will begin in Group 1, then proceed into Group 2, and lastly into Group 3. A safety review will be conducted to determine whether enrollment can be initiated into the next Group. An additional blinded safety review will be performed after all six subjects in Group 3 have completed the 48-hour Visit, in order to support dose selection for Part B (Safety and Efficacy). Part B of the study will begin enrollment only after the Sponsor has selected the two dose regimens from Part A. The study will remain blinded until completion of both parts of the study.

In Part A, up to 18 subjects will be randomized to VP-102 or placebo treatment with three different regimens. When Part B is open an additional ~90 subjects will be enrolled and randomized to VP-102 or placebo with two treatment regimens. Two of the treatment arms will be VP-102 Regimen 1 and VP-102 Regimen 2. The other two treatment arms will be placebo (Placebo Regimen 1 and Placebo Regimen 2), with corresponding durations of skin exposure matching those selected for VP-102 Regimen 1 and Regimen 2. As an example, if the regimens selected from Part A are the 2-hour and 6-hour applications of VP-102, then VP-102 Regimen 1 would be VP-102 treatment for 2-hours and VP-102 Regimen 2 would be VP-102 treatment for 6-hours. Likewise, Placebo Regimen 1 would be placebo treatment for 2 hours and Placebo Regimen 2 would be placebo treatment for 6-hours. Randomization of the four treatment arms (VP-102 Regimen 1:VP-102 Regimen 2:Placebo Regimen 1:Placebo Regimen 2) will be 3:3:2:2. In both Regimen 1 and Regimen 2, study drug will be administered to EGW once every 21 days for up to four applications. Subjects will be asked to remove the study drug at the designated time selected from the dose regimen findings in Part A of the study. Treatment will continue with a minimum of every 21 days, until complete clearance or a maximum of four treatment sessions. Safety assessments including recording of local skin reactions are conducted at each treatment visit and at follow up visits Day 84, 112, and 147.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • VP-102 and applicatorCombination product

    Also called VP-102 (cantharidin) 0.7% w/v topical solution

    In part A, VP-102 will be applied for either 2, 6 or 24 hours with each regimen compared to placebo. For part B, 2 of the regimens from part A will be chosen for Part B with each compared to Placebo. Only 4 arms are actually being studied.

  • PlaceboCombination product

    The placebo single-use applicator contains the same formulation as the VP-102 applicator but does not contain the active pharmaceutical ingredient cantharidin

Model description
The aim of Part A is to determine the two best treatment regimens for evaluation of safety and efficacy in Part B. Increasing durations of skin exposure to study drug (VP-102 or placebo) will be evaluated in three treatment groups (n=6/group) that will enroll progressively. Part B of the study will begin enrollment only after the Sponsor has selected the two dose regimens in Part A, which will be called VP-102 Regimen 1 and Regimen 2.Approximately 90 subjects will be enrolled and randomized to one of four treatment arms (two treatment regimens, each with VP-102 and Placebo). Randomization will be stratified by sex so that neither gender exceeds \~60% of any treatment arm. Two of the treatment arms will be VP-102 Regimen 1 and VP-102 Regimen 2. The other two treatment arms will be placebo (Placebo Regimen 1 and Placebo Regimen 2), with corresponding durations of skin exposure matching those selected for VP-102 Regimen 1 and Regimen 2.

A Phase 2 study testing VP-102 and applicator in people with Condylomata Acuminata and Papillomavirus Infections, run by Verrica Pharmaceuticals Inc. at 4 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 27 Nov 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 22 Sep 2021). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Proportion of Subjects Exhibiting Complete Clearance of All Treatable Warts at the Study Day 84 (End of Treatment) Visit. (time frame: Compares baseline wart count to Day 84, end of treatment.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03981822, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 27 Nov 2024.
