简要总结
The purpose of this study is to determine the safety, tolerability and efficacy of the topical application of AP611074 5% gel during 6 weeks on ano-genital warts caused by human papillomavirus (HPV).
详细描述
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 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) have limited efficacy, with a significant level of GW 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 condyloma caused by HPV infection.

入选标准
- •Male or female patient aged between 18 and 55 years.
- •External condylomas, 1-15 lesions, non-confluent and individually isolated.
- •Lesions must not be internal (ie, they must not penetrate the urethral meatus, vagina or anal canal); their visualization must be complete by patients and investigators without major facilitation maneuvers and easily documented by digital pictures.
- •Lesions should have a total surface smaller than 5 cm2, and an individual surface smaller than 1 cm2; lesions should be easily measured using a "French Catheter Scale".
- •Lesions to be treated should have appeared between 1-6 months before screening and patients should not have received any previous condyloma treatment since their appearance.
- •For patients having previous episodes of condyloma lesions, they shouldn't have received any condyloma treatment for at least 12 months before screening.
排除标准
- •Patients with any history or presence of cardiovascular, pulmonary, gastro-intestinal, hepatic, renal, metabolic, hematological, neurologic, psychiatric, systemic or infectious disease that, in the Investigator's judgment, prevents the patients from participating to the study.
- •Patients with VIN or PIN (intraepithelial neoplasia of vulva or penis; ie, Bowenoid papulosis), or genital disease (ie, lichen sclerosus, lichen planus, lichen simplex chronicus, dermatitis, psoriasis, bullous diseases, systemic diseases with genital manifestations) requiring treatment.
- •Patients with fibroepithelial polyps or scaly non-viral papillomas, seborrheic keratosis, follicular papules, syringoma, or circumscribed lymphangiomas.
- •Patients whose skin condition or coloration would interfere with the observation and the follow-up of the lesions during the study.
- •Patients for whom a proper follow-up of the lesions during the study will not be possible, because of hair growth in the treatment area.
