E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate any difference in plasma Lyso gl3 measure and clinical outcomes in gastrointestinal involvement in patients with GI involvement switched from agalsidase alfa to beta. |
valutare eventuali differenze nella misurazione del Lyso GL3 plasmatico e gli esiti clinici nel coinvolgimento gastrointestinale in pazienti con coinvolgimento GI passati da agalsidasi alfa a beta |
|
E.2.2 | Secondary objectives of the trial |
to identify differences in intestinal microbiota composition in a cohort of patients switched from a standard dose of agalsidase alfa to agalsidase beta. |
identificare differenze nella composizione del microbiota intestinale in una coorte di pazienti passati da una posologia standard di agalsidasi alfa ad agalsidasi beta. |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
• Informed Consent signed, before any trial procedures are performed • Male or female patients • Age =18 years • Confirmed diagnosis of Fabry disease and concomitant treatment with standard dose of agalsidase alfa for at least 1 years, without any dose modification • Presence of continuous gastrointestinal involvement for the previous 4 months before the screening, with at least 1 symptom reported in the GRSG questionnaire • Elevated plasma lyso-GL3 (plasma lyso-Gl3 > 7 ng/ml)
|
• Firma del consenso informato, prima di qualsiasi procedura prevista dallo studio • Pazienti di sesso maschile o femminile • Età =18 anni • Diagnosi di malattia di Fabry confermata, e trattamento concomitante con dose standard di agalsidasi alfa da almeno un anno, senza alcuna modifica della posologia • Presenza di manifestazioni gastrointestinali in maniera continua nei 4 mesi precedenti la visita di screening, con almeno uno dei sintomi riportati nel questionario GSRS • valori elevati di lyso-GL3 plasmatico (plasma lyso-Gl3 > 7 ng/ml)
|
|
E.4 | Principal exclusion criteria |
• plasma lyso-Gl3= 7 ng/ml at baseline and/or no evidences of GI symptoms. • Patients with a diagnosis of chronic inflammatory diseases defined according to the criteria of the International Classification: gastroenterological, rheumatologic, immunologic autoimmune diseases • Patients diagnosed with any type of cancer in evolution • Patients diagnosed with infectious disease certified through microbiological tests performed in the last 12 months (included in the medical history of the patient) • Patients with IBD, Celiac disease or other inflammatory chronic disease such as Crohn disease or rectal ulcerative colitis (RUC ) • Pregnancy or lactation • Concomitant medication with chloroquine, amiodarone, benoquin or gentamycin, due to a theoretical risk of inhibition of intra-cellular a- Gal A activity. • Known allergy to one or more of the components of agalsidase beta
|
• Livelli plasmatici di lyso-Gl3= 7 ng/ml al basale e/o nessuna evidenza di manifestazioni gastrointestinali . • Pazienti con diagnosi di malattie infiammatorie croniche, definite secondo I criteri di classificazione internazionale: gastrointestinali, reumatologiche, immunologiche ed autoimmunitarie • Pazienti con diagnosi di neoplasie • Pazienti con diagnosi di malattie infettive certificate da test microbiologici eseguiti negli ultimi 12 mesi (incluso nella storia clinica del paziente) • Pazienti con sindrome dell’intestino irritabile, con malattia celiaca o altre malattie infiammatorie croniche intestinali come malattia di Crohn o rettocolute ulcerosa • stato di gravidanza o allattamento • concomitante terapia con clorochina, amiodarone, benoquina o gentamicina, in relazione al rischio teorico di inibilre l’attività intracellultare dell’enzima a- Gal A. • Allergie note ad uno o più componenti dell’agalsidasi beta

E.5 End points |
E.5.1 | Primary end point(s) |
1. The primary endpoint will be focused on the evaluation of plasma level of Lyso GL3 and gastrointestinal symptoms evaluated through the validated scale “Gastrointestinal Symptom Rating Scale” (GSRS) at baseline and after the switch from agalsidase alfa to beta. |
L'endpoint primario sarà focalizzato sulla valutazione del livello plasmatico di Lyso GL3 e dei sintomi gastrointestinali valutati attraverso la scala validata "Gastrointestinal Symptom Rating Scale" (GSRS) al basale e dopo il passaggio da agalsidasi alfa a beta. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
|
E.5.2 | Secondary end point(s) |
Intestinal microbiota: three samples intestinal fecal will be recollected at baseline and at the time of standard follow up to evidence any differences in the colonization of intestinal bacteria. |
Analisi del microbiota intestinale: tre campioni di feci intestinali saranno raccolte al basale e al momento del follow up standard per evidenziare eventuali differenze nella colonizzazione dei batteri intestinali. |
