Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

All

Description

Inclusion Criteria:

  1. Healthy male and female subjects ≥ 18 years of age, with external genital warts. The health status is verified by absence of evidence of any clinical significant active or uncontrolled chronic disease other than genital warts following a detailed medical history and a complete physical examination including vital signs and 12-lead ECG. In the case of uncertain or questionable results, tests performed during screening may be repeated before randomization to confirm eligibility or judged to be clinically irrelevant for healthy subjects.
  2. Clinically diagnosed and biopsy confirmed external genital warts. Subject has at least 3 external genital warts.
  3. Willing to give written informed consent and willing and able to comply with the study protocol.

Exclusion Criteria:

Eligible subjects must meet none of the following exclusion criteria at screening:

  1. Clinically significant abnormalities, as judged by the Investigator, in laboratory test results including haematology, blood chemistry panel, virology or urinalysis. In the case of uncertain or questionable results, tests performed during screening may be repeated before randomization to confirm eligibility or judged to be clinically irrelevant for healthy subjects.
  2. Current clinically significant skin conditions in the anogenital area (e.g. atopic dermatitis, lichen sclerosus, lichen planus or psoriasis).
  3. Pregnant, breast feeding or trying to conceive.
  4. Participation in an investigational drug or device study within 3 months prior to screening or more than 4 times a year.
  5. Loss or donation of blood over 500 mL within three months (males) or four months (females) prior to screening.
  6. Use of active treatment (i.e. cryotherapy, laser therapy, topical medication and/or surgical treatments) for genital warts within 28 days prior to first study drug administration.
  7. Immunosuppressed patients, having an immunodeficiency (primary or secondary, like HIV) or receiving immunosuppressive therapy (i.e. Transplant patients).
  8. Males or Females who received a vaccination with Gardasil or Cervarix.
  9. Any (medical) condition that would, in the opinion of the Investigator, potentially compromise the safety or compliance of the patient or may preclude the patient's successful completion of the clinical trial.
