      This is a Phase 2, open label study (Study number VP-102-105; referred to as COVE-1

Eligibility criteria:

        Inclusion Criteria:

          1. Be healthy, immunocompetent males or females at least 2 years of age and older for
             Cohort 1 and 12 years of age and older for Cohort 2.

          2. Present with 1-6 common warts (verruca vulgaris) located anywhere on the body except
             for the following prohibited areas: the eye area (including eyelids), lips, oral
             cavity, nasal cavity, inside of the ears, palms of the hands, volar surface of the
             fingers or toes, under the finger nails (near and on the sides of the nails is allowed
             for Cohort 1, but warts near and on the sides of the nail (e.g., periungual) are not
             allowed in Cohort 2), soles of the feet, or the anogenital area. (Warts within 10 mm
             of a mucosal surface should not be treated).

          3. Have warts that are ≤10 mm in diameter and ≤3 mm in height. (Subjects with warts that
             are adjacent, touching or clustered may be included so long as the combined diameter
             in the longest direction does not exceed 10 mm. Individual lesions that are adjacent,
             touching or clustered should be counted as distinct lesions for the purposes of
             tracking, inclusion and clearance)(subjects in Cohort 2 can be pared, when necessary
             and appropriate, prior to evaluating height eligibility) .
