E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Explore the value of T-cell responses to LL37 and ADAMTSL5 auto-antigens in psoriasis and the impact of IL-17A inhibition on these responses. |
Esplorare il ruolo della risposta T cellulare agli auto-antigeni LL37 e ADAMTSL5 nella psoriasi e quale sia l’impatto dell’inibizione di IL-17A sulla risposta T cellulare. |
|
E.2.2 | Secondary objectives of the trial |
Explore the value of LL37 and ADAMTSL5 auto-antibody formation in psoriasis and the effects of IL17A inhibition. Explore the phenotype of autoreactive T cells following IL17A inhibition by secukinumab. |
Esplorare il ruolo della formazione di autoanticorpi anti-LL37 e anti-ADAMTSL5 nella psoriasi e l’effetto sugli stessi dell’inibizione di IL-17A. Esplorare il fenotipo delle cellule T auto-reattive dopo inibizione di IL-17A a seguito di trattamento con secukinumab. |

E.3 | Principal inclusion criteria |
Subject has provided informed consent. Subject is =18 and = 80 years of age at time of screening. Subject has had stable moderate to severe plaque psoriasis for at least 6 months (eg, no morphology changes or significant flares of disease activity in the opinion of the Investigator). Subject has an SI index >2 for LL37 and/or ADAMTSL5 at baseline. Patients negative to LL37 and ADAMTSL5 will be included in the study to receive secukinumab but will be only clinically evaluated (PASI, IGA). Subject has involved body surface area (BSA) = 10%, PASI = 10, at baseline . For women (except those at least 2 years postmenopausal or surgically sterile): a negative serum pregnancy test during screening and a negative urine pregnancy test at baseline. Subject has no known history of active tuberculosis. Subject has a negative test for tuberculosis during screening defined as either: negative purified protein derivative (PPD) (< 5 mm of induration at 48 to 72 hours after test is placed). OR negative Quantiferon test. Subjects with a positive PPD and a history of Bacillus Calmette-Guérin vaccination are allowed with a negative Quantiferon test. Subjects with a positive PPD test (without a history of Bacillus Calmette-Guérin vaccination) or subjects with a positive or indeterminate Quantiferon test are allowed if they have all of the following: no symptoms per tuberculosis worksheet provided by the Sponsor. documented history of adequate prophylaxis initiation prior to receiving study drug in accordance with local recommendations. no known exposure to a case of active tuberculosis after most recent prophylaxis . no evidence of active tuberculosis on chest radiograph within 3 months prior to the first dose of investigational product. Subject is a candidate for systemic therapy or phototherapy. Previous failure, inadequate response, intolerance, or contraindication to at least 1 conventional anti-psoriatic systemic therapy (eg, cyclosporine, psoralen plus ultraviolet light [UV] A). Subject should not be previously treated with secukinumab or other biologics for psoriasis. Subject is able to complete study procedures, including self-assessments and self-injections. |
• Il soggetto ha fornito il consenso informato. • Il soggetto ha un'età =18 e = 80 anni al momento dello screening. • Il soggetto ha avuto una psoriasi a placche stabile da moderata a grave per almeno 6 mesi (p. Es., Nessun cambiamento morfologico o riacutizzazione significativa dell'attività della malattia secondo il parere dello sperimentatore). • Il soggetto ha un indice SI> 2 per LL37 e / o ADAMTSL5 al basale. • I pazienti negativi a LL37 e ADAMTSL5 saranno inclusi nello studio per ricevere secukinumab ma saranno valutati solo clinicamente (PASI, IGA). • Il soggetto ha una superficie corporea interessata (BSA) = 10%, PASI = 10, al basale. • Per le donne (eccetto quelle da almeno 2 anni in postmenopausa o chirurgicamente sterili): un test di gravidanza su siero negativo durante lo screening e un test di gravidanza sulle urine negativo al basale. • Il soggetto non ha una storia nota di tubercolosi attiva. • Precedente fallimento, risposta inadeguata, intolleranza o controindicazione ad almeno 1 terapia sistemica antipsoriasica convenzionale (p. Es., Ciclosporina, psoralene più luce ultravioletta [UV] A). • Il soggetto non deve essere precedentemente trattato con secukinumab o altri farmaci biologici per la psoriasi. |
|
E.4 | Principal exclusion criteria |
Skin disease related Subject diagnosed with erythrodermic psoriasis, pustular psoriasis, guttate psoriasis, medication-induced psoriasis, or other skin conditions at the time of the screening visit (eg, eczema) that would interfere with evaluations of the effect of investigational product on psoriasis. Other medical conditions SEE PROTOCOL |
• Malattia della pelle correlata • Soggetti con diagnosi di psoriasi eritrodermica, psoriasi pustolosa, psoriasi guttata, psoriasi indotta da farmaci o altre condizioni della pelle al momento della visita di screening (ad es. Eczema) che potrebbero interferire con le valutazioni dell'effetto del prodotto in studio sulla psoriasi. • Il soggetto ha un intervento chirurgico pianificato durante la durata dello studio. • Il soggetto ha un'infezione attiva o una storia di infezioni ricorrenti o - Il soggetto ha una storia nota di virus dell'immunodeficienza umana • Soggetto non controllato, clinicamente significativo • Il soggetto ha una storia di ipersensibilità al principio attivo o ad uno qualsiasi degli eccipienti di secukinumab |
