Definitions
- the present invention relates to the treatment of chronic infections caused by human papillomaviruses. It relates more particularly to the use of an inhibitor of the interleukin 17 pathway for treating HPV infections.
- HPV Human Papillomavirus
- HPV HR high carcinogenic potential
- HPV LR mucosal types with low carcinogenic potential
- Warts and condylomas are a clinical translation of non-oncogenic HPV chronic skin infections.
- HPV HR high-risk oncogenic HPV
- Cutaneous tropism HPV is mainly responsible for benign tumor lesions: vulgar warts (in particular foxgloves), flat warts, mosaic warts, myrmecies (deep wart), or papillomas and condylomas. Although these lesions are considered benign, they constitute a very frequent reason for consultation because of their painful nature and the social embarrassment of which they are often responsible.
- the most frequently proposed therapies are topical (salicylated vaseline, imiquimod, liquid nitrogen cryotherapy). These treatments are often disappointing because they have no effect on viral replication, which explains the chronicity and frequent recurrence of these lesions (Kwok et al., 2011).
- HPV epidermodysplasia verruciforme
- This immunodepression thus exposes as the genetic terrain of EV to a susceptibility to infection of these HPV associated with EV and the risk of developing skin squamous cell carcinoma. This is particularly illustrated in cases of congenital HIV infection with EV charts in young children infected with HIV (Lowe et al., 2012).
- HPV infection associated with EV is greater in the skin of patients with psoriasis, which makes the role of these viruses as an alloantigen inducing or perpetuating psoriasis lesions (Mahé et al. ., 2003).
- HPV low risk oncogene HPV LR
- HPV infection is an important source of gynecological diseases, with cervical cancer being the second most common cancer in women worldwide (Source: WHO). There are currently 3000 new cases per year in France and 1000 annual deaths related to this cancer (Source: National Cancer Institute).
- HPV infections we distinguish between non-oncogenic HPV infections and oncogenic HPV infections, known as high-risk (HR) infections.
- HR high-risk
- HPV 6 and 11 the HPV 6 and 11 at the origin of the condyloma, which can sit on the vulva, the vagina or the cervix.
- HPV cervical infection develops in the first years of sexual life and affects the vast majority of women: it is the most common sexually transmitted infection. Most infected women spontaneously eliminate HPV in 6 to 24 months, with the prevalence of infection decreasing significantly after 30 years. However, for a minority of women, the infection may persist, leading in some cases to precancerous cervical lesions: CIN (cervical intraepithelial neoplasia) (Schiffman et al., 2007). Again, most of these lesions will regress spontaneously with the elimination of the virus, but some will persist for several years and then progress to more and more severe stages (CIN1 to CIN3) to invasive cancer (most often squamous type). ) 10 to 15 years after the appearance of the first CIN.
- CIN cervical intraepithelial neoplasia
- the algorithm for the management of pre-neoplastic cervical lesions is based on the grade of severity.
- Low-grade lesions (CIN1) have a low potential for progression to invasive cancer, so it is recommended not to treat and monitor closely.
- CIN2 and 3 the risk of transformation is greater, the current therapeutic attitude of gynecologists consists of a treatment by cryotherapy or laser vaporization of the cervix for CIN2 and conization for CIN3, less frequently for CIN2.
- the management of CIN remains debated because of their possible regression in case of spontaneous viral clearance but as a precaution the clinicians usually opt for a systematic treatment.
- Cancer of the anus is rare and currently represents less than 5% of colorectal cancers but its incidence is increasing. It occurs most often after age 60 and is more prevalent in women.
- the main etiologic factor is chronic HPV HP infection, which is present in 95% of cases of precancerous lesions (Anal Intraepithelial Neoplasia or AlN) which, if left untreated (laser vaporization, imiquimod, surgical excision ...) may progress to invasive cancer (Weis, 2013).
- AlN Anal Intraepithelial Neoplasia
- the prevalence of AIN in the general population is currently poorly known due to lack of screening.
- the male homosexual population is particularly at risk of developing AIN.
- Squamous cell carcinomas of the male external genitalia and more particularly the glans are infrequent but 75% of cases are associated with HPV infection HR, and have a natural history similar to that described in the cervix, with the evolution of intraepithelial neoplasia of the penis (PIN) to an invasive carcinoma.
- the preputial balano groove constitutes a "reservoir" for HPV viruses, as evidenced by the lower prevalence of viral carriage in circumcised men compared with uncircumcised men. This reservoir may be a source of self-inoculation of HPV to other mucosal sites, and may contribute to the chronicity of HPV infections in sexual partners (Martin-Ezquerra et al., 2012).
- HRV HPV infection In HIV-infected patients, the prevalence of HRV HPV infection in anogenital sites is particularly high (60% in women and more than 90% in homosexual men). HPV infections are often multiple involving several viral oncogenic genotypes and the persistence of infection is more common, which promotes the occurrence of precancerous and cancerous lesions. Thus cervical lesions in HIV-positive women are very common, which justifies an annual screening of cervical cancer in this population. Similarly, the risk of invasive squamous cell carcinoma of the anus is significantly increased in the male homosexual HIV + population. It is therefore recommended to offer regular screening with anesthesia, especially for men with multiple partners.
- HRV-induced lesions are proportional to the duration of HIV infection: in patients who have been infected for more than 15 years, the incidence is 12-fold higher than that observed in patients infected for less than 5 years, which reflects the natural history of HPV but also the low impact of antiretrovirals on chronic HPV infections (Piketty et al., 2013).
- HPV vaccination is a key element in the fight against cervical cancer, but because of its recent introduction, low vaccine coverage and the natural history of HPV infections, its impact the incidence of HPV lesions will not be felt for ten years or more. In addition, these vaccines only protect against a few genotypes of HPV. Current recommendations are therefore to continue screening for cervical cancer in women who have been vaccinated.
- Interleukin 17 is a pro-inflammatory cytokine produced by helper T cells of type 17 (Th17). Six isoforms were identified (IL-17A to IL-17F) as well as 5 ubiquitous expression receptors (IL-17RA to IL-17RE) (Gaffen, 2009).
- L-17A is a homodimer (A / A) or a heterodimer (A / F) associated with IL-17F.
- This family of interleukins is involved in a large number of inflammatory diseases such as psoriasis, rheumatoid arthritis, inflammatory bowel diseases.
- Secukinumab (developed by Novartis) is an IgG1 monoclonal antibody that binds selectively to IL-17A. This molecule was developed following the demonstration of high concentrations of IL-17 in psoriatic lesions as well as in the serum of patients with psoriasis; which testifies to the role of IL-17 in deregulation of the cutaneous immune system, a key phenomenon in the pathophysiology of psoriasis. L-17A Neutralization is a novel therapeutic approach to psoriasis that provides very promising clinical results with an excellent safety profile (Langley et al., 2014). Several therapeutic approaches aimed at using an inhibitor of IL-17 pathway to treat psoriasis have therefore been developed, some of which are in clinical trials and others have been granted marketing authorization.
- IL-17 is also involved in the defense against certain fungal (Bar et al., 2014) and bacterial microbial agents, as well as in the carcinogenesis of certain tumors (Wang et al., 2009).
- the inventors propose using an inhibitor of the IL-17 pathway to treat chronic HPV infections, especially non-oncogenic infections.
- This new therapeutic approach is based (i) on the recent findings on the role of IL-17 mentioned above and (ii) on several clinical observations on the effect of anti-IL-17 on carriage of different types of mucosal HPV (HPV LR and HPV HR), as well as pre-neoplastic benign cutaneous lesions (wart) and cervical skin lesions, which are clinical manifestations exclusively related to HPV infection .
- HPV LR and HPV HR mucosal HPV
- pre-neoplastic benign cutaneous lesions wart
- cervical skin lesions pre-neoplastic benign cutaneous lesions
- these clinical observations show that anti-IL-17 antibodies, in particular antibodies specific for IL-17A, have an effect on both cutaneous HPVs and mucosal HR or LR HPVs.
- the present invention firstly relates to the use of an inhibitor of the IL-17 pathway for treating chronic infections due to one or more HPV.
- Chronic HPV infections include several conditions that differ depending on whether or not the HPVs involved are oncogenic and whether they are cutaneous or mucosal.
- chronic HPV infection within the meaning of the invention is meant a chronic infection of keratinocytes by one or more HPV subtypes.
- Skin damage can result from non-oncogenic HPV infections such as warts and papillomas; or infections with oncogenic HPV as in the case of verruciform epidermoplasias (EVR).
- non-oncogenic HPV infections such as warts and papillomas
- EMR verruciform epidermoplasias
- Mucosal involvement may also result from non-oncogenic HPV infections such as anogenital warts and laryngeal papillomatosis; or oncogenic HPV infections such as preneoplastic lesions and squamous cell carcinoma of the cervix, ENT, anus and glans.
- non-oncogenic HPV infections such as anogenital warts and laryngeal papillomatosis
- oncogenic HPV infections such as preneoplastic lesions and squamous cell carcinoma of the cervix, ENT, anus and glans.
- the invention consists in using an inhibitor of the IL-17 pathway to treat a chronic infection caused by one or more HPVs chosen from warts, condylomas, laryngeal papillomatosis, laryngeal verruciform epidermoplasia, as well as preneoplastic lesions and squamous cell carcinoma sitting among gynecological, ENT, anal and penile sites.
- the inhibitor of the IL-17 pathway is an inhibitor of the IL-17A pathway.
- the invention consists in administering an inhibitor of the IL-17 pathway in a patient suffering from warts, in order to make them disappear.
- the effectiveness of such treatment is reported in the clinical case presented in the experimental part. Indeed, the administration of an anti-IL-17A antibody in patients with warts having resisted conventional treatments has allowed a significant regression or even complete cutaneous lesion in 3 months.
- this clinical result makes it possible to propose the administration of an inhibitor of the IL-17 pathway, in particular an IL-17A inhibitor, in particular an IL-17A-specific antibody to treat chronic non-oncogenic HPV skin and mucosal infections responsible for clinical manifestations resistant to conventional treatments such as warts, condylomas and papillomas.
- the inhibitor of the IL-17 pathway for example an anti-IL-17A, particularly advantageously an IL-17A specific antibody, is administered in a patient infected with one or more oncogenic HPV and cervical preneoplastic lesions (CIN) to achieve regression of these lesions without resorting to invasive therapeutic protocols.
- CIN cervical preneoplastic lesions
- This approach aims to treat oncogenic chronic mucosal HPV infections to prevent their progression to invasive cancer.
- the inhibitor of the IL-17 pathway is administered systemically in a chronically infected patient with one or more oncogenic HPV with CIN present.
- this inhibitor may be administered in the context of the management of invasive cervical cancers.
- the purpose of such treatment is to reduce the risk of tumor recurrence by limiting the replication of persistent latent HPV after treatment of invasive cancer.
- the decrease in the risk of recurrence concerns both recurrence at the initial site and the lesional periphery.
- the invention comprises administering an inhibitor of the IL-17 pathway, for example an anti-IL-17A, to an immunocompromised individual suffering from chronic mucosal infections due to one or more HPVs. RH. Since these subjects have an increased risk of developing cancerous lesions in case of persistent HPV HP infection, the proposed treatment would therefore, by controlling the viral infection, limit this risk. Immunocompromised patients who may benefit from such treatment include HIV-infected individuals and transplant recipients.
- an inhibitor of the IL-17 pathway for example an anti-IL-17A
- the invention comprises administering an inhibitor of the IL-17 pathway to a subject having EV.
- An inhibitor of the IL-17 pathway should be able to control HPV infection associated with EV and prevent the development of benign and malignant skin lesions associated with these viruses.
- EV could be a quasi-experimental model for judging the effectiveness of this therapeutic approach.
- the treatment of viral infection means the control of viral replication and the regression of clinical and cellular lesions induced by chronic HPV infection.
- HPV viral infection by an inhibitor of the IL-17 pathway can be attributed to two modes of action:
- IL-17 Anti-proliferative effect by inhibiting the direct effect of IL-17 on the proliferation and differentiation of keratinocytes, as in the case of the treatment of psoriasis.
- the inhibitor of the IL-17 pathway decreases the proliferation of infected keratinocytes, resulting in decreased HPV viral load.
- the viral infection being limited, the proliferation of keratinocytes will also be amplifying the phenomenon of virological control.
- inhibitor of the IL-17 pathway within the meaning of the invention is meant any compound or any molecule capable of inhibiting the IL-17 signaling pathway.
- an inhibitor or antagonist may be an antibody or an antibody fragment directed against IL-17 or against the IL-17 receptor (IL-17R), an IL-17 soluble receptor, a chemical compound or any chimeric agent.
- the IL-17 inhibitor is an IL-17 specific antagonist antibody.
- This inhibitor of the IL-17 pathway can specifically bind to IL-17A, IL-17B, IL-17C, IL-17D, IL-17E or IL-17F, or their respective receptors.
- such an inhibitor is an IL-17A specific antibody or a soluble receptor specific for IL-17A.
- anti-IL17 antibodies for example of anti-IL-17 antibodies
- secukinumab Novartis
- ixekizumab Eli Lilly
- ANB004 AnaptysBio Inc.
- Other antibodies targeting the IL-17 receptor have been developed, such as brodalumab (Amgen).
- the term "antibody” is intended to mean a monoclonal antibody or an antibody fragment, for example the F (ab ') 2 , F (ab) or scFv fragments which bind specifically to IL-17 or any peptide comprising a domain of the initial antibody recognizing IL-17.
- the term antibody also covers antibody variants well known to those skilled in the art, such as chimeric or humanized antibodies.
- the inhibitor of the IL-17 pathway can be administered locally, intralesionally, or systemically.
- secukimumab can be administered systemically, by subcutaneous injection at the dose of 300 mg for 5 consecutive weeks, and then at one injection every 4 weeks.
- This treatment regimen is that which has been applied to patients in whom the administration of an anti-IL-17A has allowed a significant or complete regression of warts in 3 months; these cases are presented in detail in the experimental part.
- This same treatment regimen corresponds to that followed by patients in whom the administration of an anti-I L-17A has reduced the genital carriage of HPV both HR and LR in three months; these cases are presented in detail in the experimental part.
- This pattern also corresponds to that followed by a patient with cytologic abnormalities on the cervical smear performed during the initiation of treatment with anti-I L-17-A, lesions which totally regressed after 4.5 months of treatment.
- the dosage and the route of administration can be adapted to the type of inhibitor employed and according to the lesions to be treated; the person skilled in the art, and in particular the doctor in charge of the patient, will be able to determine the appropriate dose, as well as the periodicity of the administration.
- Figure 1 Evolution of a wart located on the index of a patient treated with secukinumab. 1A: before treatment; 1B: after one month of treatment; 1C: after two months of treatment.
- Figure 2 Evolution of a digital wart located at the root of the middle finger of a patient treated with secukinumab. 2A: before treatment; 2B: after three months of treatment.
- Clinical case Complete disappearance of a cutaneous wart during treatment with secukinumab.
- BACKGROUND The clinical case is a 29-year-old patient who was referred for psoriasis with a PASI index of 14.5 who had resisted several therapeutic lines, including phototherapy and systemic treatment with acitretin and methotrexate. In addition, this patient had a wart located on the pulp of the right index which had been evolving for 8 months, treated iteratively by cryotherapy and salicylic acid applications, without success (Figure 1A).
- treatment with secukinumab As part of the management of psoriasis, treatment with secukinumab (anti-IL17, developed by Novartis) was initiated according to the following scheme: weekly subcutaneous injections at a dose of 300mg for 5 weeks, then monthly injection.
- Treatment As part of the management of psoriasis, treatment with secukinumab (anti-IL17, developed by Novartis) was initiated according to the following scheme: weekly subcutaneous injections at a dose of 300mg for 5 weeks, then monthly injection. Result: The follow-up showed, after three months of treatment, a complete regression of the warts in a patient ( Figure 2), as well as a clear decrease in the size of the warts (regression of the order of 50% of the surface of warts) in the other two patients.
