What is being measured

The primary outcome is the main question the study is designed to answer.

The Primary Efficacy Endpoint is the Number of Subjects Whose Identified Common Warts Are Determined to be Clear on the PWA Scale (PWA=0) at Visit 10 (Day 60)
The primary efficacy endpoint is the number of subjects whose identified common warts are determined to be clear on the Physician Wart Assessment (PWA) scale (PWA=0) at Visit 10 (Day 60).
Efficacy will be assessed using the Physician's Wart Assessment Scale (PWA) which is a 4 point scale. A higher amount of warts cleared represents a better outcome.
Measured: Day 60

Secondary outcomes (4)

Number of Subjects With Complete Clearance of All Treated Common Warts Between Active and Vehicle on the Physician Wart Assessment (PWA) Scale (PWA=0) at Visit 13 (Day 137)
Number of subjects whose identified common warts are determined to be clear on the Physician Wart Assessment (PWA) scale (PWA=0) at Visit 13 (Day 137).
Efficacy will be assessed using the Physician's Wart Assessment Scale (PWA) which is a 4 point scale. A higher amount of warts cleared represents a better outcome.
Measured: Day 137
Mean Per-Subject Percent of All Warts That Were Clear on the Physician Wart Assessment (PWA) Scale Between Active and Vehicle That Are Clear (PWA=0) at Visit 13 (Day 137)
Mean Per-Subject Percent of All Warts That Were Clear on the Physician Wart Assessment (PWA) Scale Between Active and Vehicle That Are Clear (PWA=0) at Day 137.
Clearance of all treated warts will be assessed using the Physician Wart Assessment (PWA) scale which is a four point scale. A higher amount of warts cleared represents a better outcome.
Measured: Day 137
Number of Subjects With a Single Wart at Baseline Whose Wart Was Clear on the PWA Scale Between Active and Vehicle Group (PWA=0) at Visit 10 (Day 60)
Comparison between Active (A-101 45%) and Vehicle of subjects with a single wart at baseline, whose wart is clear (PWA=0) at Day 60.
Clearance of the single wart at baseline will be assessed using the Physician Wart Assessment (PWA) scale which is a four point scale. A higher amount of warts cleared represents a better outcome.
Measured: Day 60
Median Time for Subjects to Achieve Clearance (PWA=0) of All Treated Common Warts
Comparison between Active (A-101 45%) and Vehicle with respect to the median time to achieve onset of clearance (PWA=0) for all treated warts at Day 137.
Clearance of all treated warts will be assessed using the Physician Wart Assessment (PWA) scale which is a four point scale. A higher amount of warts cleared represents a better outcome.
Measured: Day 137

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing A-101 in people with Common Wart, run by Aclaris Therapeutics, Inc. at 24 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 15 inclusion and 27 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 5 Oct 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 24 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. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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 5 Oct 2020). 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?

The Primary Efficacy Endpoint is the Number of Subjects Whose Identified Common Warts Are Determined to be Clear on the PWA Scale (PWA=0) at Visit 10 (Day 60) (time frame: Day 60). 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 NCT03687372.

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 5 Oct 2020.
