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 to 50 years (Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Have 2 or more genital warts of prespecified sizes on external surfaces of the body.
  • If HIV positive, have HIV RNA < 400 copies/mL, CD4 count of ≥ 400 cells/mm3, and be taking a triple combination antiviral medication regimen

Exclusion Criteria:

  • Prior genital wart treatment within 8 weeks
  • Pregnancy or breast-feeding
  • Presence of broken or non-intact skin near the wart site or other skin disease at the wart site (e.g., herpes genitalis)
  • Treatment with systemic steroids, systemic immunomodulators, immunosuppressants, or chemotherapeutic agents within 3 months
  • Current or prior diagnosis of Bowenoid papulosis, cancer, or pre-cancerous tissue in the genital area
