Registered outcomes5
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | 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) | 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. |
| Secondary | 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) | 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. |
| Secondary | 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) | 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. |
| Secondary | 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) | 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. |
| Secondary | Median Time for Subjects to Achieve Clearance (PWA=0) of All Treated Common Warts | Day 137 | 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. |

|---|---|---|---|---|---|
| PRIMARY | 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) | Day 60 | The study's primary endpoint was to evaluate the amount of patients achieving a clearance of all baseline WARTS. Patients were stratified by the amount of WARTS at Baseline. | Participants | COUNT_OF_PARTICIPANTS |
| SECONDARY | 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) | Day 137 | The secondary 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 13 (Day 137).~Efficacy will be assessed using the Physician's Wart Assessment Scale (PWA) which is a 4 point scale. | Participants | COUNT_OF_PARTICIPANTS |
