4. Subject has had any Human Papilloma Virus (HPV) vaccine within 1 year prior to enrollment

5. Subject has used any of the following intralesional therapies within the specified period prior to enrollment to the Target Wart:

• Immunotherapy (Candida antigen, mumps antigen, Trichophyton antigen);

• Anti-metabolite therapy (bleomycin, 5-fluorouracil)

6. Subject has used any of the following systemic therapies within the specified period prior to enrollment:

• Immunomodulatory/immunosuppressant therapy (e.g., etanercept, alefacept, infliximab);

• Glucocortico-steroids (inhaled and intra-nasal steroids are permitted);

7. Subject has used any of the following topical therapies within the specified period prior to enrollment on, or in a proximity to the Target Wart, which in the Investigator's opinion, might put the subject at undue risk by study participation or interfere with the study conduct or evaluations:

• LASER (pulsed-dye laser), light (intense pulsed light, photo-dynamic therapy, other energy based therapy); Immuno-therapy ( imiquimod, squaric acid dibutyl ester, etc.); Anti-metabolite therapy (5-fluorouracil); Retinoids; Liquid nitrogen, electrodesiccation, curettage; Over-the-counter wart therapies

8. Subject has had any of the following within the specified period prior to enrollment on, or in a proximity to the target lesion, which in the Investigator's opinion, might put the subject at undue risk by study participation or interfere with the study conduct or evaluations:

• A cutaneous malignancy;

• A pre-malignancy (actinic keratosis)

9. Subject has a history of sensitivity to any of the ingredients in the study medications

10. Subject has any current skin disease (psoriasis, atopic dermatitis, eczema, sun damage, etc.), skin condition (sunburn, open wounds) or other disease or condition (uncontrolled diabetes) which, in the Investigator's opinion, might put the subject at undue risk by study participation or interfere with the study conduct or evaluations

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Efficacy Based on Mean Change in Physician Wart Assessment Over Time	The primary effectiveness will consist of the mean change from Visit 2 to Visit 10 in Physician Wart Assessment (PWA) performed using Analysis of Covariance (ANCOVA) with Visit 2 PWA as the covariate. Physician Wart Analysis is a measurement scale from 0 to 3 that evaluates the wart with 0 being clear and 3 being clinically diagnosable wart that is raised, with an obviously rough surface.	57 Days
Secondary	Durability of Response - Percentage of Participants That Were Clear at Visit 10 That Are Still Clear at Visit 13	Percentage of subjects whose target wart was clear at Visit 10 and who remained clear at Visit 13 for active treatment groups	visit 10 to visit 13
Secondary	PWA Responder	The percentage of participants who were responders with the target wart judged to be clear (PWA = 0) at Visit 10.	Day 57
