Conditions

Summary

This is a Phase 3, double-blind, randomized, vehicle-controlled study (Study number VP-CW-301; referred to as COVE-2 \[Cantharidin and Occlusion in Verruca Epithelium\]) to evaluate the efficacy and safety of YCANTH (VP-102) treatment in subjects with common warts.


Eligibility

Min Age: 2 Years

Inclusion Criteria13

  • Candidates will be included in the study if they:
  • Are male or female patients ≥ 2 years of age.
  • Are immunocompetent.
  • Have a minimum of 1 treatable common wart (verruca vulgaris) of any size and height:
  • Common warts are considered treatable if they are located anywhere on the body, except for the following excluded areas: the eye area (including eyelids), lips, oral cavity, nasal cavity, inside of the ears, soles of the feet (plantar warts), subungual spaces (ie, under the fingernail or toenail), or the anogenital area (warts within 10 mm of a mucosal surface should not be treated).
  • If treatment of these excluded wart types is required during the study, it should be limited to destructive therapy such as cryosurgery and warts cannot be within 10 mm of any warts that are under study.
  • Have no systemic or dermatologic disorder, which, in the opinion of the Investigator, will interfere with the study results or increase the risk of AEs.
  • Agree to refrain from swimming, bathing, or prolonged immersion in water or any liquids until the study drug is removed after each treatment.
  • Have the ability, or have a parent/guardian with the ability, to follow study instructions and the willingness to complete all study requirements.
  • Agree not to use any wart-removing product (prescription or over-the-counter) other than the study drug during the course of the study, with the exception of circumstances allowed under Inclusion Criterion 3b.
  • Provide written informed consent or assent in a manner approved by the IRB and/or have a parent/guardian provide written informed consent as evidenced by the signature on an IRB approved assent/consent form. Subjects who turn 18 years of age (or legal age per state or country) during the study will be required to re-consent to remain on the study.
  • Provide written authorization for use and disclosure of protected health information (per state and/or country requirements).
  • If participating in the optional photographic assessment, agree to allow photographs of treatable common warts to be taken at selected visits by the research team.

Exclusion Criteria17

  • Candidates will be excluded from the study if they:
  • Are unable to cooperate with the requirements or visits of the study, as determined by the Investigator.
  • Have any warts present at Baseline in an allowed anatomic location that the subject, parent/guardian, or Investigator is unwilling to treat.
  • Plantar warts and external genital warts will not be included in this study, in addition, subungual warts and warts within 10 mm of a mucosal surface will not be included in this study due to their anatomical location and complex treatment modalities.
  • Are systemically immunosuppressed or have taken required systemic immunosuppressive or immunomodulatory medication (including oral or parenteral corticosteroids) within 30 days before enrollment or such treatment is planned to be required during the course of the study. Routine use of local (eg, topical, inhaled, intranasal) corticosteroids and episodic use of systemic medications to treat conditions arising 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 (eg, human immunodeficiency virus, systemic lupus erythematosus, viral hepatitis, uncontrolled diabetes).
  • Have had any previous treatment (including an investigational agent in a clinical trial) of common warts, including but not limited to the use of cantharidin, imiquimod, antivirals, retinoids, topical salicylic acid, lactic acid, hydrogen peroxide, trichloroacetic acid, pulse dye laser, iodine-based or nitric oxide-based therapies, oral cimetidine, coix seed, intralesional immunotherapy, curettage, or freezing of warts in the 90 days before treatment.
  • Have more common warts, or wart area, to be treated than can be adequately covered with the contents of 2 study drug applicators, as determined by total wart surface area. Each applicator can cover approximately 1500 mm2 for a total of approximately 3000 mm2 using the 2 study drug applicators.
  • Immunizations (eg, flu shots) may be administered throughout the study, but not within 5 days before or after any treatment with study drug and will be recorded as concomitant therapies in the eCRF.
  • Have received any investigational product as part of a clinical trial NOT related to the treatment of common warts within 30 days before the first application of the study drug.
  • Have epidermodysplasia verruciformis.
  • 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 (eg, subjects who required hospitalization in the 2 months before screening for an acute or chronic condition including alcohol or drug abuse), as determined by the Investigator.
  • Are sexually active or may become sexually active and are unwilling to practice a highly effective method of birth control (eg, combination of condoms and foam; oral contraceptives; intrauterine device with or without hormone release; transdermal, injectable, or intravaginal contraception). Withdrawal is not an acceptable method of birth control. Females who have reached menarche must have a negative urine pregnancy test at each visit before treatment with study drug.
  • Are pregnant or breastfeeding.

Interventions

COMBINATION_PRODUCTVP-102

A single-use applicator and applied in sufficient quantity to cover the entirety of each treatable common wart, including approximately a 1 to 2 mm margin of surrounding, healthy skin. The contents of no more than 2 applicators may be applied at each treatment visit. Each applicator contains 0.45 mL of 0.7% w/v cantharidin. Occlusive tape (occlusive tape with similar properties should be used across all clinical sites) will be applied to warts that have been treated. Once applied, the occlusive tape should be gently rubbed to maximize adherence to the treated area.

COMBINATION_PRODUCTVehicle

Vehicle is contained in a single-use applicator and applied in sufficient quantity to cover the entirety of each treatable common wart, including approximately a 1 to 2 mm margin of surrounding, healthy skin. The contents of no more than 2 applicators may be applied at each treatment visit. The Vehicle applicator contains the same excipient formulation as the VP-102 applicator but does not contain the active pharmaceutical ingredient cantharidin. Occlusive tape (occlusive tape with similar properties should be used across all clinical sites) will be applied to warts that have been treated. Once applied, the occlusive tape should be gently rubbed to maximize adherence to the treated area.
