Proportion of Subjects With Treatment Emergent AEs After Application of A-101 45% for the Treatment of Common WartsBaseline to a maximum of 341 daysSafety exposure will be measured by the proportion of subjects exposed to A-101 45% who have emergent adverse events. In order to be eligible for A-101-WART-303, subjects must have completed protocol treatment on either the A-101-WART-301 or A-101-WART-302 study. The A-101-WART-303 study was an open-label with a single arm where all subjects received A-101 Topical Solution 45% twice a week. Since A-101-WART-303 is an extension study, statistical analyses were performed by stratifying patients by treatment arms in the A-101-WART-301 or A-101-WART-302 studies. In the A-101-WART-303 study, subjects will be followed every 6 weeks to assess for a recurrence or development of new common warts. If a recurrence occurs or a new wart develops these subjects may return to the site to receive A-101 Topical Solution 45% twice a week for an additional treatment cycle of 8 weeks.

Proportion of Subjects With Treatment Emergent AEs After Application of A-101 45% for the Treatment of Common Warts

Time frame: Baseline to a maximum of 341 days

Population: The amount of patients in the various treatment cycles differs because patients without wart recurrences or new warts developing may not return for additional treatment cycles.

The A-101-WART-303 study was an open-label with a single arm where all subjects received A-101 Topical Solution 45% twice a week. Since A-101-WART-303 is an extension study, statistical analyses were performed by stratifying patients by treatment arms in the A-101-WART-301 or A-101-WART-302 studies. 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.

Time frame: Baseline to a maximum of 248 days

Population: The amount of patients in the various treatment cycles differs because patients without wart recurrences or new warts developing may not return for additional treatment cycles.
