Eligibility Criteria

2 Years - undefined (Child, Adult, Older Adult)All SexesAccepts Healthy Volunteers

Inclusion Criteria:

  4. Be otherwise medically healthy with no clinically significant medical history as determined by the investigator. Patients exhibiting active Atopic Dermatitis may be enrolled.
  5. Refrain from application of all topical agents including alcohol-based sanitary products and sunscreens for a minimum of 4 hours before Study drug application. Topical agents including alcohol-based sanitary products and sunscreens may be used after application of the study drug so long as they are not applied to or near treated skin.
  6. Refrain from swimming, bathing or prolonged immersion in water until the Study drug is removed.
  7. Have the ability or have a guardian able to follow study instructions and be likely to complete all study requirements.
  8. Provide assent in a manner approved by the institutional review board (IRB) and have a parent/guardian provide written informed consent as evidenced by signature on IRB approved assent/consent forms.
  9. Provide written authorization for use and disclosure of protected health information.
  10. Agree to allow photographs of all selected lesions to be taken and/or send photos via text or email to the study team for assessment at 24 hours post treatment.

  7. 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.
  8. Have a history or presence of hypersensitivity or an idiosyncratic reaction to the Study drug or related compounds, or drug product excipients.
  9. Have a condition or situation that may interfere significantly with the subject's participation in the study (e.g., patients 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.
  10. Have received another investigational product within 14 days prior to the first application of the Study drug.
  11. Have been treated within 14 days with a product that contains the active ingredient in VP-102 (topical or homeopathic preparations) for any reason prior to screening.
  12. Are sexually active or may become sexually active and are unwilling to practice responsible birth control methods. Females that have reached menarche, must have a negative urine pregnancy test at screening and each visit prior to treatment with study medication.

Outcomes

Primary Outcome Measures

The Presence or Absence of Systemic Exposure to Cantharidin by the Collection and Analysis of Plasma Samples From Patients With 21 or More Molluscum Lesions Following Treatment of VP-102.
The primary objective is to determine any potential systemic exposure from a single 24-hour dermal application of VP-102 topical film-forming solution when applied to molluscum contagiosum (molluscum) lesions on pediatric subjects 2 years old and older.

Secondary Outcome Measures

Measurement of Efficacy - Complete Clearance
Proportion of subjects exhibiting complete clearance of all treated molluscum lesions (baseline and new) on or before Week 12 (EOS).

5. Study Description

Brief Summary
The primary objective of the study is to determine the presence or absence of systemic cantharidin exposure from a single 24-hour dermal application of VP-102 topical film-forming solution [0.7% (w/v) cantharidin] (VP-102) when applied to molluscum contagiosum (molluscum) lesions on pediatric subjects 2 years old and older. Treatment will continue over the course of 3 additional 21 day intervals allowing for further evaluation of safety, efficacy and impact on quality of life.
Detailed Description
This is a Phase 2, Open-Label Study to Evaluate the Safety, Efficacy and Systemic Exposure of VP-102 Topical Film Forming Solution [0.7% (w/v) cantharidin] in subjects 2 years and older with Molluscum Contagiosum. Up to 40 subjects will be enrolled in the study with the goal of 16 meeting criteria for, and completing all scheduled blood draws outlined in the exposure portion of the trial. Subjects that do not have enough molluscum lesions to participate in the exposure study but do meet all other criteria to participate in the study will be enrolled in the standard treatment group. No more than 16 subjects will complete exposure group activities; up to 16 subjects will be enrolled in the standard treatment group. The additional 8 subjects may be used for replacement patients. At least 3 patients in the exposure group will be from 2-5 years of age. All subjects will receive VP-102 containing 0.7% cantharidin to molluscum lesions every 21 days for a maximum of 4 sessions or until complete clearance. In the exposure group, blood samples for systemic exposure evaluation will be collected on Day 1, prior to the drug application, and 2 (± 30 minutes), 6 (± 1 hour) and 24 (±3 hours) hours post-application. A dermatological examination will be performed by a qualified investigator quantifying molluscum lesion counts at every study visit.
