| Eligibility | Inclusion Criteria: Proof of Concept Study: - Male or non-pregnant female 5 years of age or older. - Written consent (adults) and written assent (minors). - Subjects with a minimum of two clinically diagnosed verrucae 4 cm in diameter or less in a similar treatment area. - Subjects must be willing and able to apply the occlusive heat patch(s) as directed, comply with study instructions and return to the clinic for required visits. - Women of childbearing potential (WOCBP) must agree to use an effective form of birth control for the duration of the study (abstinence, stabilized on oral contraceptives or contraceptive patches for at least three months, implant, injection, intrauterine device, NuvaRing®, condom and spermicidal or diaphragm and spermicidal). Abstinence is an acceptable form of birth control for subjects who are not sexually active. Subjects that become sexually active during the trial must agree to use an effective, non-prohibited form of birth control for the duration of the study. Confirmation Study: - Male or female 5 -25 years of age at the baseline visit. - Written consent (adults) and written assent (minors). - Subjects with one clinically diagnosed verruca, 2-20 mm in largest diameter. - Subjects must be willing and able to apply the study patch as directed, comply with study instructions and return for required visits. Exclusion Criteria: Proof of Concept Study: - Subjects who are immunocompromised for any reason or are known to be HIV+ based on medical history taken at screening. - Subjects taking any of the following systemic therapy with 4 weeks of enrollment; cimetidine, systemic steroids, immunomodulators or immunosuppressants. - Subjects who have used any anti-verruca treatments within 4 weeks. These include but are not limited to topical salicylic acid preparations, imiquimod (Aldara), podophyllin containing preparations, surgical procedures, immunotherapy, among others. - Subjects who have active localized or systemic medical conditions that in the opinion of the investigator, would preclude their participation in the study or interfere with their assessment of their verrucae. - Subjects with any underlying disease(s) or a dermatological condition of the affected area(s) that requires the use of interfering topical or systemic therapy. - Subjects with verruca, for treatment, that are located in the periungual, genital, or head regions or have mosaic warts. - Subjects with verruca, for treatment, that is associated with significant scarring from prior therapy in the opinion of the investigator. - Subjects who are unable to communicate or cooperate with the Investigator due to language problems, poor mental development, or impaired cerebral function. - Subjects with any condition which, in the investigator's opinion, would make it unsafe for the subject to participate in a research study. - Subjects with a history of allergy or sensitivity to any of the components or the patches (including the adhesives). - Subjects who are currently enrolled in a clinical drug or device research study. - Subjects who have been treated with another investigational device or drug within 30 days prior to study enrollment. - Subject is pregnant, nursing or planning a pregnancy during the study period Confirmation Study: - Subjects who are immunocompromised for any reason or are known to be HIV+ based on medical history taken at screening. - Subjects taking any of the following systemic therapy within 4 weeks of enrollment; cimetidine, systemic steroids, immunomodulators or immunosuppressants. - Subjects who have used any destructive anti-verruca treatments within 4 weeks. These include but are not limited to cryotherapy, topical salicylic acid preparations, podophyllin-containing preparations, intralesional bleomycin, or surgical procedures. No immunotherapy (topical allergens or intralesional antigen injections) or topical sinecatechins ointment, imiquimod cream 6 months before baseline visit. - Subjects who have active localized or systemic medical conditions that in the opinion of the investigator, would preclude their participation in the study or interfere with their assessment of their verrucae. - Subjects with any underlying disease(s) or a dermatological condition of the affected area(s) that requires the use of interfering topical or systemic therapy. - Subjects with verrucae only located in the genital or head regions or possessing only mosaic, flat or filiform warts. - Subjects with verrucae only located in areas with significant scarring from prior therapy in the opinion of the investigator. - Subjects who are unable to communicate or cooperate with the investigator due to language problems, poor mental development, or impaired cerebral function. - Subjects with any condition which, in the investigator's opinion, would make it unsafe for the subject to participate in a research study. - Subjects with a history of allergy or sensitivity to any of the components of the patches (including the liquid adhesive and adhesive remover). - Subjects who are currently enrolled in a clinical drug or device research study. - Subjects who have been treated with another investigational device or drug within 30 days prior to study enrollment. - Subject is pregnant, nursing or planning a pregnancy during the study period. - During the study, concomitant use of the following medications or treatments is PROHIBITED: - Systemic corticosteroids, immunosuppressants, immunomodulators, cimetidine. Topical treatments to the area containing the target verruca intended to treat warts including, podophyllin, salicylic acid preparations, intralesional bleomycin, surgical procedures or immunotherapy (topical allergens or intralesional antigen injections) or topical sinecatechins ointment and imiquimod cream among others. - Medications or treatments that might interfere with the evaluation of the occlusive patch should not be used. - Changes in general skin care treatment during the study should also be discouraged. - There will be no use of medication which, in the opinion of the investigators, will interfere with the study results. |

|---|---|---|---|---|
| Primary | Percent reduction in verrucae diameter - proof of concept study | Efficacy will be determined by the percent reduction in verruca diameter (Lesion Measurement). A severity grade will be given to the target and control warts using the Investigator Global Improvement Score (IGIS). IGIS scale scores are as follows: 4 = Same or worse, 3 = Minimal Improvement, 2 = Marked Improvement, 1 = Almost Clear, 0 = Clear. | 12 weeks | |
| Primary | Count of participants with an IGS score = 0 on target verruca - confirmation study | To assess the efficacy of the heat patch in the confirmation study, the count of subjects (in each arm and combined) achieving an IGIS of 0 (complete clearance) of the target verruca will be assessed. Investigator Global Improvement Score (IGIS) scale scores are as follows: 4 = Same or worse, 3 = Minimal Improvement, 2 = Marked Improvement, 1 = Almost Clear, 0 = Clear. | 24 weeks | |
| Primary | Count of participants with an IGS score = 0 on at least 1 non-target verruca - confirmation study | To assess the efficacy of the heat patch in the confirmation study, the count of subjects greater than one verruca that demonstrate clearance of one or more than one non-target verruca will be assessed. Investigator Global Improvement Score (IGIS) scale scores are as follows: 4 = Same or worse, 3 = Minimal Improvement, 2 = Marked Improvement, 1 = Almost Clear, 0 = Clear. | 24 weeks | |
| Secondary | Count of participants with an IGS score = 0 on target verruca - confirmation study | To assess the efficacy of the heat patch in the confirmation study, the count of subjects (in each arm and combined) achieving an IGIS of 0 (complete clearance) of the target verruca will be assessed.
