Detailed Description:
All subjects will receive study drug containing 0.7% cantharidin topical film forming solution. Dermatologic exams, wart counts, measurement of diameter and height of each wart and Evaluation of Response to Treatment (ERT) will be conducted by a qualified member of the research team at Treatment Visits 1, 2, 3 and 4 as well as at the End of Study (EOS) Visit. Evaluations are to be conducted prior to treatment application when applicable.

Arm Intervention/treatment
Open label
This is an open label study. All subjects will receive treatment to their common warts per protocol with VP-102, cantharidin topical film forming solution, using the VP-102 applicator.
Drug: VP-102-cantharidin topical film forming solution
VP-102 cantharidin topical film forming solution.
Other Name: Subjects will receive treatment to their warts with VP-102

Device: VP-102 Applicator
The applicator is used to apply the Study drug.The product is a combination therapy which includes the drug VP-102 and the applicator which is the device.




Primary Outcome Measures :
  1. Proportion of subjects exhibiting complete clearance of all treatable warts (baseline and new) at the End of Study Visit. [ Time Frame: Treatment Visit Day 1 (Baseline) compared to Day 84 (EOS) Visit. ]

Secondary Outcome Measures :
  1. Proportion of subjects exhibiting complete clearance of all treatable warts (baseline and new) at Visit 2, Visit 3 and Visit 4. [ Time Frame: Wart clearance assessed at each treatment visit Day 14, 28 and 42. ]

Other Outcome Measures:
  1. Percent reduction of all treatable warts (baseline and new) from baseline at Visit 2, Visit 3, Visit 4 and the EOS visit. [ Time Frame: Compare Treatment Visit 1 (Baseline) to Treatment Visits 2 (day 14), 3 (Day 28), 4 (Day 42) and at End Of Study (Day 84; EOS). ]
  2. Change from baseline in the number of treatable warts (baseline and new) at Visit 2, Visit 3, Visit 4 and the EOS visit. [ Time Frame: Compare Treatment Visit 1 (Baseline) to Treatment Visits 2 (Day 14), 3 (Day 28), 4 (Day 42) and End of Study (Day 84; EOS). ]
  3. Proportion of subjects exhibiting ≥ 50% clearance of all treatable warts (baseline and new) at the EOS visit as compared to baseline. [ Time Frame: Compare Treatment Visit 1 (Baseline) to End of Study (Day 84; EOS). ]
  4. Proportion of subjects who respond to treatment defined by a ≥ 50% reduction in total wart area at EOS compared to baseline. [ Time Frame: Compare Treatment Visit 1 (Baseline) to End of Study (Day 84; EOS). ]

Ages Eligible for Study:   2 Years and older   (Child, Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Be healthy, immunocompetent males or females at least 2 years of age or older.
  • 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, under the finger nails (near and on the sides of the nails is allowed), soles of the feet, or the anogenital area. (Warts within 10 mm of a mucosal surface should not be treated).
  • All warts must be ≤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).
  • All warts must be present for at least 4 weeks at baseline visit.
  • Consent to having all warts treated (the physician must also be willing to treat all warts initially present).
  • Be otherwise medically healthy with no clinically significant medical history, physical examination or vital signs as determined by the investigator.
  • Are free of any systemic or dermatologic disorder, which, in the opinion of the investigator, will interfere with the study results or increase the risk of AEs.
  • Refrain from swimming, bathing or prolonged immersion in water or any liquids until the Study drug is removed.
  • Have the ability, or have a guardian with the ability, to follow study instructions and be likely to complete all study requirements.
  • Agree to use no wart-removing product (prescription or over-the-counter [OTC]) other than the Study drug during the course of the study.
  • Provide written informed consent or assent in a manner approved by the institutional review board (IRB) and/or have a parent/guardian provide written informed consent as evidenced by the signature on an IRB approved assent/consent form.
  • Provide written authorization for use and disclosure of protected health information.
  • Subjects that agree to participate in the optional photos portion of the study: Agree to allow photographs of warts to be taken at each treatment visit by the research team and agree to share photos taken at home with the research team via text, email or in-person upload.

Exclusion Criteria:

  • Are unable to cooperate with the requirements or visits of the study, as determined by the investigator.
  • Are systemically immunosuppressed or have required, or will require, systemic immunosuppressive or immunomodulatory medication (including oral or parenteral corticosteroids) within 30 days prior to enrollment or during the course of the study. (Routine use of inhaled or intranasal corticosteroids during the study is allowed.)
  • Have any chronic or acute medical condition that in the opinion of the investigator, may interfere with the study results or place the subject at undue risk. (e.g., human immunodeficiency virus, systemic lupus erythematosus, viral hepatitis, uncontrolled diabetes).
  • Have more than 6 common warts at baseline.
  • Present with any verruca plana, mosaiform, filoform, subungual (under the nail), genital or anal warts.
  • Have any warts present at baseline in an anatomic location the subject, parent/guardian or the physician is unwilling to treat or is located in an area that cannot be easily occluded tape.
  • Have had any previous treatment of common warts including but not limited to the use of cantharidin, antivirals, retinoids, salicylic acid, lactic acid, hydrogen peroxide, candida antigen, diphencyprone, dinitrochlorobenzene, sandalwood oil, thuja oil, squaric acid dibutyl ester, povidone iodine, curettage or freezing of warts in the past 14 days. In addition, these treatments or any other over-the-counter wart treatment should not be implemented during the course of the study.
  • Have been treated within 14 days with a product that contains cantharidin (topical or homeopathic preparations) for any reason prior to screening.
  • Have received another investigational product as part of a clinical trial within 30 days prior to the first application of the Study drug.
  • Currently have, or have a history of, epidermodysplasia verrucifomis.
  • Have a history of illness or any dermatologic disorder, which, in the opinion of the investigator, will interfere with accurate assessment of the warts or increase the risk of adverse events.
  • Have an active malignancy or are undergoing treatment for any malignancy.
  • Have a history or presence of clinically significant medical, psychiatric, or emotional condition or abnormality that, in the opinion of the investigator, would compromise the safety of the subject or the quality of the data.
  • Have a history or presence of hypersensitivity or an idiosyncratic reaction to the Study drug or related compounds, or drug product excipients (acetone, ethyl alcohol, nitrocellulose, hydroxypropyl cellulose, castor oil, camphor, gentian violet, and denatonium benzoate).
  • Have a condition or situation that may interfere significantly with the subject's participation in the study (e.g., subjects who required hospitalization in the 2 months prior to screening for an acute or chronic condition including alcohol or drug abuse), at the discretion of the investigator.
  • Are sexually active or may become sexually active and are unwilling to practice responsible birth control methods. (e.g., combination of condoms and foam, birth control pills, intrauterine device, patch, shot and vaginal ring, etc.). Withdrawal is not an acceptable method of birth control.
