About this study

People who participated in either the COVE-2 or COVE-3 study for common warts, may be eligible to enroll into this Long Term Follow Up (LTFU) study COVE-4. The main question(s) to answer in this LTFU study are: * To assess the safety of YCANTH (also known as VP-102 in the United Sates or TO-208 in Japan) by assessing concomitant medication use, and adverse events (AEs), including expected local skin reactions (LSRs). * To evaluate the efficacy of continued skin application of YCANTH (VP-102/TO-208) when applied to each common wart once every 21 days for a maximum of 4 additional treatments. Participants with eligible common warts present will receive YCANTH (VP-102/TO-208) with an interval of 21 (± 4) days between applications until there is a wart count of zero (ie, completed clearance has been achieved) or a maximum of 4 additional treatments. Participants with complete clearance will attend Observation Visits at intervals of 42 (± 4) days without treatment. Participants who develop a new wart after having a wart count of zero will resume Treatment Visits every 21 (± 4) days for a maximum of 4 additional treatments. All subjects will attend visits until the End-of-Study (EOS) Visit, which is on Day 378 (0/+ 8 days). If participants still have warts present after 4 additional treatments of YCANTH (VP-102/TO-208) the wart(s) will be discontinued from study and participants will be allowed to seek treatment but should be limited to destructive therapy such as cryosurgery an…
