Definitions
- the present invention provides a compound selected from macrocyclic lactones for use in treating and / or preventing a complication of human papillomavirus infection.
- Papillomaviruses belong to the family Papovaviridae (genus Papillomaviridae). They are small viruses (50 to 55 nm in diameter), consisting of a nucleocapsid of 72 capsomeres. Their genome consists of a double-stranded DNA molecule of about 8000 base pairs. These viruses have been identified in many mammalian species, in birds and reptiles. However, papillomaviruses are highly specific for the host species, and no cross-infection with other species has been observed ("Papillomavirus Infections," Medico-Surgical Encyclopedia, 2004, 8-054-A-10).
- Papillomaviruses have a particular tissue tropism for the skin and squamous mucous membranes. Human papillomavirus (HPV) is thus associated with specific anatomical localizations and characteristic lesions. However, these localizations are not exclusive since under certain conditions, such as in the case of immunosuppression, usually genital papillomaviruses may be associated with cutaneous lesions for example. Cutaneous or mucosal infections and their complications can affect the hands, feet, limbs, trunk, head, neck, face or mucosa anogenital, oral and laryngeal.
- HPV plays an etiological role in the development of precancerous and cancerous lesions. Initiated since 1976, this link was confirmed in the mid-1990s, thanks to molecular biology techniques, especially between certain HPV (including HPV 16 and 18) and cervical cancers. There is currently no treatment for the destruction of viruses.
- Visible lesions can, however, be more or less easily removed.
- Lesions of the cervix are treated by cryotherapy, laser, or even surgery (removal of part or all of the cervix).
- cryotherapy In order to suppress condyloma (or genital warts), local medicinal treatments exist, in particular based on podophyllotoxin, trichloroacetic acid or imiquimod. To be effective, these assets require a prolonged application over time.
- Other treatments exist as physical treatments such as laser vaporization, curettage electrocoagulation or cryotherapy. These treatments may have the disadvantage of leaving scars after treatment.
- current treatments rely primarily on the destruction of infected cells and not on the virus itself. Insofar as subclinical infection is not detectable (that is to say without visible clinical manifestations), these treatments are carried out only on the lesions themselves and not on a sufficiently large surface to avoid relapses.
- HPV treatments described above have disadvantages such as irritation and intolerance phenomena, especially when they are used for a long time.
- these treatments are only suppressive and non-curative, acting in particular on the visible lesions and not on the infection itself.
- the subject of the present invention is thus a compound chosen from macrocyclic lactones for use in treating and / or preventing a complication of infection by a human papillomavirus chosen from malignant melanomas, cutaneous carcinomas, in-situ or invasive carcinomas.
- squamous cell carcinomas Bowen's disease, head and neck cancers, upper aerodigestive tract cancers, laryngeal cancers, esophageal cancers, stomach cancers, oral papillomas, pharyngeal papillomas, laryngeal papillomas, oesophageal papillomas, lung cancers, intravascular neoplasia, intravaginal neoplasia, intracervical neoplasia, cervical dysplasia, carcinoma of the cervix, penile cancer, intrapenous neoplasia, and in-situ or invasive carcinomas.
- the complications of infection with a human papillomavirus are selected from malignant melanomas, cutaneous carcinomas, in-situ or invasive carcinomas, squamous cell carcinomas, Bowen's disease, head cancers. and neck.
- the invention also relates to the use of a compound among macrocyclic lactones or their pharmaceutically acceptable salts for the preparation of a medicament for treating complications of infection with a human papillomavirus as defined above.
- the invention also relates to a method comprising administering a compound selected from macrocyclic lactones or pharmaceutically acceptable salts thereof to a patient for treating complications of human papillomavirus infection as defined above.
- treatment refers to an improvement, prophylaxis of a disease or disorder, or at least one symptom discernible therefrom.
- treatment or “treating” means an improvement, the prophylaxis of at least one measurable physical parameter associated with the disease or disorder being treated, which is not necessarily discernible in or by the subject treaty.
- treatment means inhibiting or slowing down the progression of a disease or disorder, physically, for example, stabilizing a discernible symptom, physiologically, for example, the stabilization of a physical parameter, or both.
- treatment means delaying the onset of a disease or disorder.
- compounds of interest are administered as a preventive measure.
- prevention or “prevention” means a reduction in the risk of acquiring a specified disease or disorder.

- HPV when HPV enters the germinal cells of the basal epithelial layer, following microlysis, it multiplies in the tissue, taking advantage of the differentiation of keratinocytes.
- viral multiplication with complete synthesis of the virion is observed only in the most superficial layers of the epidermis, when the cell is well differentiated.
