E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
evaluate whether DF2156A has a potential in improving the clinical outcome in patients with active blistering BP to warrant its further development and the safety of DF2156A in the specific clinical setting |
valutare se il DF2156A ha un potenziale nel migliorare l'esito clinico in pazienti con PB in fase bollosa attiva da supportare un suo ulteriore sviluppo e valutare la tollerabilita' del DF2156A nell'ambito clinico specifico |

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Consented male and female patients aged >50 years with newly diagnosed or relapsing bullous pemphigoid (clinical diagnosis to be confirmed by direct immunofluorescence and indirect immunofluorescence on salt-spit skin or BP180 and/or BP230 ELISA) will be included. Patients must have mild to moderate active blistering disease (total number of blisters between 1 and 30) whether associated or not with urticarial/eczematous lesions and a modified ABSIS score ≤50. Patients must be free from any systemic treatments that may affect the course of the disease (off-period prior to enrolment: 3 weeks for steroids, dapsone, tetracyclines, nicotinamide; 3 months for azathioprine, mycofenolate mofetil, cyclophosphamide, methotrexate, intravenous immunoglobulins, immunoadsorption, TNF antagonists; 12 months for rituximab, leflunomide). They must also be free from any topical treatments other than topical antibiotics and antiseptics in the 4 days prior to enrolment. |
Saranno inclusi pazienti di entrambi i sessi che abbiano dato il consenso informato, di età >50 anni con PB di nuova diagnosi o recidivante (la diagnosi clinica deve essere confermata tramite immunofluorescenza diretta e indiretta o saggio ELISA per BP180 e/o BP230). I pazienti devono avere patologia in fase attiva di grado lieve o moderato (numero totale di bolle compreso tra 1 e 30), associata o meno a lesioni orticarioidi/eczematose e un ABSIS score modificato <= 50. I pazienti non devono assumere nessun farmaco sistemico che potrebbe modificare l'evoluzione della patologia (periodo di assenza da questi trattamenti prima dell'arruolamento: 3 settimane per steroidi, dapsone, tetracicline, nicotinamide; 3 mesi per azatioprina, micofenolato mofetile, ciclofosfamide, metotrexate, immunoglobuline intravenose, immunoassorbimento, antagonisti del TNF; 12 mesi per rituximab e leflunomide). Non devono inoltre essere trattati con alcun farmaco topico ad eccezione degli antibiotici e degli antisettici nei 4 giorni precedenti l’arruolamento. |

E.4 | Principal exclusion criteria |
Patients will be excluded if they have a Karnofsky rating score <40% and a mucosal involvement. Patients who have moderate to severe renal impairment (calculated creatinine clearance < 50 mL/min according to the Cockcroft-Gault formula) or hepatic dysfunction (increased ALT/AST > 3 x upper limit of normal and increased total bilirubin > 3 mg/dL [>51.3 μmol/L]) or hypoalbuminemia (serum albumin < 3 g/dL) or a QTcF > 470 msec or had a myocardial infarction in the previous 6 months will be excluded as well. Patients will be excluded if they are on treatment with phenytoin, warfarin, sulphanylurea hypoglycemics and high dose of amitriptyline (> 50 mg/day); if they have a known hypersensitivity to non-steroidal antiinflammatory drugs; if they received an investigational product in the 12 months prior to enrolment. Also, pregnant or breast feeding women or patients unwilling to use effective contraceptive measures (females and males) will be excluded. |
Saranno esclusi dallo studio i pazienti che hanno uno score di Karnofsky <40% e un coinvolgimento mucosale. Inoltre, saranno esclusi i pazienti con disfunzione renale moderata o severa (clearance della creatinina calcolata secondo la formula di Cockcroft-Gault < 50 mL/min); disfunzione epatica (ALT/AST superiori di tre volte il limite superiore di normalità e bilirubina totale > 3 mg/dL [>51.3 μmol/L]); ipoalbuminemia (albumina serica < 3 mg/dL); un QTcF > 470 msec; pazienti che abbiano avuto un infarto del miocardio nei 6 mesi precedenti. Saranno esclusi pazienti in trattamento con fenitoina, warfarin, ipoglicemizzanti sulfanilureici e alte dosi di amitriptilina (> 50 mg al giorno); con ipersensibilità nota agli antiinfiammatori non-steroidei; che abbiano ricevuto un farmaco sperimentale nei 12 mesi antecedenti l'arruolamento. Inoltre, saranno escluse le donne in stato di gravidanza o in allattamento o pazienti (donne e uomini) che non desiderano utilizzare un metodo efficace di contraccezione. |
