Primary Outcome Measures:
  • Complete or partial regression of anogenital warts, based on the total lesion surface before and after treatment [ Time Frame: 6 weeks ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Safety and local tolerability [ Time Frame: Up to 8 weeks ] [ Designated as safety issue: Yes ]
    Descriptive statistics will be calculated by comparing the number of subjects between Day 1 and Day 42 in each treatment group (active or placebo) presenting AEs, or changes in physical examination, vital signs (blood pressure and pulse rate), 12-lead ECG, clinical laboratory parameters (biochemistry, hematology, urinalysis), and local tolerability (erythema, scaling, stinging, oedema)

  • Pharmacokinetic evaluation [ Time Frame: Up to 8 weeks ] [ Designated as safety issue: No ]
    Plasma concentrations of AP611074 will be measured from blood samples once weekly up to 8 weeks in all patients. Data will be summarized with descriptive statistics by nominal sampling time.

Estimated Enrollment: 24
Study Start Date: January 2012

Estimated Primary Completion Date: May 2013 (Final data collection date for primary outcome measure)

Detailed Description:
Genital warts (GW; also called condylomas or condylomata acuminata) are lesions caused by infection of Human papillomavirus (HPV)(specifically HPV-6 or HPV-11 types, found in > 95% of lesions). GW are sexually transmitted and affect about 1% of the sexually active population. GW do not affect the vital prognostic of a patient, but represent a distressful condition for social and sexual life, especially in the cases of external condylomas. No HPV-specific antiviral treatment exists to date, and all existing therapies (either surgical or drug) are not completely efficient, show recurrences and are associated with local skin reactions. AP611074 is a synthetic new chemical entity that is a potent and selective inhibitor of the interaction between two viral proteins from HPV6 and HPV11, an interaction that is a necessary step for HPV DNA replication and thus viral production. AP611074 is the "first in class" specific HPV antiviral described to treat pathologies caused by HPV infection.

Main Inclusion Criteria:

  • External condylomas, 1-15 lesions, non-confluent and individually isolated
  • Lesions must not be internal; their visualization must be complete and easily documented by digital pictures.
  • Lesions to be treated should have appeared between 1-6 months before screening, and should not have received any treatment since appearance.
  • Non smoker or light smoker (< 10 cigarettes/day).
  • Certified as healthy by a comprehensive clinical assessment.
  • Having given a written informed consent prior to selection.
