Patent

CA 2609927

The current invention provides improved methods and means for the treatment of virally induced intraepithelial neoplasias of the ano-genital tract, such as HPV induced vulvar-, cervical-, vaginal-, penile- and anal intraepithelial neoplasias (VIN, CIN, VAIN, PIN and AIN). The invention provides a method of treatment of a subject suffering from an anogenital intraepithelial neoplasia comprising at least the steps of first determining whether the subject has a T- cell reactivity for viral early antigens, in particular high risk type HPV antigens; and subsequently a local treatment of the neoplasia with immune modulating compounds eliciting local inflammation if the subject scores positive for the T-cell reactivity, preferably a CD4+ response against HPV early antigens. The invention also comprises methods and means to induce or further stimulate a cellular immune response against HPV antigens, prior to or during treatment with the immune modulating compound capable of eliciting a local inflammatory response.

L'invention concerne des procédés et moyens améliorés permettant de traiter des néoplasies intraépithéliales du tractus anogénital induites par des virus, par exemple les néoplasies intraépithéliales vulvaires, cervicales, vaginales et péniennes (VIN, CIN, VAIN, PIN et AIN). L'invention concerne également un procédé permettant de traiter un patient qui souffre d'une néoplasie intraépithéliale anogénitale qui consiste au moins en premier lieu à déterminer si le patient présente une réactivité aux lymphocytes T pour des antigènes précoces viraux, en particulier des antigènes HPV du type à risque élevé; et par la suite, à traiter localement la néoplasie avec des composés à modulation immunitaire élicitant une inflammation locale lorsque le patient affiche positif pour la réactivité aux lymphocytes T, de préférence une réponse CD4+ contre des antigènes précoces HPV. L'invention concerne en outre des procédés et des moyens permettant d'induire ou de stimuler une réponse immunitaire cellulaire contre des antigènes HPV avant ou pendant le traitement au moyen du composé de modulation immunitaire pouvant éliciter une réponse inflammatoire locale.
