E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To determine the efficacy of tirzepatide in increasing endogenous insulin production in patients with Wolfram syndrome type 1 (WS1) |
Determinare l'efficacia della tirzepatide nell'aumentare la produzione endogena di insulina in pazienti con sindrome di Wolfram di tipo 1 (WS1) |
|
E.2.2 | Secondary objectives of the trial |
To determine the efficacy of tirzepatide in correcting glycemic lability in Wolfram syndrome type 1 |
Determinare l'efficacia della tirzepatide nel correggere la labilità glicemica nella sindrome di Wolfram di tipo 1 |
|

E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
Other types of substudies Specify title, date and version of each substudy with relative objectives: Title: "Induced pluripotent stem cells (iPSCs) from patients with Wolfram syndrome Type 1 as a model for predicting response to tirzepatide treatment" The main objective of this sub-study is the generation of induced pluripotent stem cell (iPSC) lines from peripheral blood of 10 Wolfram syndrome Type 1 (WS1) patients recruited in the phase II interventional study entitled "Towards a personalized precision medicine in rare disease: tirzepatide (a dual glucose-dependent insulinotropic polypeptide and glucagon-like peptide-1 receptor agonist) monotherapy in patients with Wolfram syndrome type 1." iPSCs derived from WS1 patients will be differentiated into ß cells, and the basic characteristics and functional properties of ß cells treated or not treated with tirzepatide will be examined. A correlation analysis will then be performed between the cellular and patient response to tirzepatide

Altre tipologie di sottostudi specificare il titolo, la data e la versione di ogni sottostudio con i relativi obiettivi: Titolo: "Cellule staminali pluripotenti indotte (iPSC) da pazienti con sindrome di Wolfram di tipo 1 come modello per prevedere la risposta al trattamento con tirzepatide" L’obiettivo principale di questo sotto studio è la generazione di linee di cellule staminali pluripotenti indotte (iPSC) a partire da sangue periferico di 10 pazienti affetti da sindrome di Wolfram di Tipo 1 (WS1) reclutati nello studio interventistico di fase II dal titolo “Towards a personalized precision medicine in rare disease: tirzepatide (a dual glucose-dependent insulinotropic polypeptide and glucagon-like peptide-1 receptor agonist) monotherapy in patients with Wolfram syndrome type 1”. Le iPSC derivate dai pazienti WS1 verranno differenziate in cellule ß e verranno esaminate le caratteristiche di base e le proprietà funzionali delle cellule ß trattate o meno con tirzepatide. Verrà poi effettuata un’analisi di correlazione fra la risposta cellulare e quella del paziente a tirzepatide

E.3 | Principal inclusion criteria |
1) A definite diagnosis of Wolfram syndrome, as determined by the following: (a) Documented diabetes mellitus diagnosed under 16 years of age according to WHO or ADA criteria; and (b) Documented functionally relevant recessive mutations on both alleles of the WFS1 gene or dominant mutation on one allele of the WFS1 gene based on historical test results (if available) or from a qualified screening laboratory; 2) aged 5 years or older; 3) The patient, the patient's parents or legally authorized guardian(s) must have voluntarily signed an informed consent form approved by the Institutional Review Board/Independent Ethics Committee after all relevant aspects of the study have been explained and discussed with the patient . Guardian consent and patient consent, if applicable, must be obtained; 4) Women of childbearing age will be included only after a highly sensitive negative urine pregnancy test.

1) Una diagnosi definitiva di sindrome di Wolfram, come determinato da quanto segue: a) Diabete mellito documentato diagnosticato sotto i 16 anni compiuti secondo i criteri OMS o ADA e b) Mutazioni recessive funzionalmente rilevanti documentate su entrambi gli alleli del gene WFS1 o mutazione dominante su un allele del gene WFS1 sulla base dei risultati dei test storici (se disponibili) o da un laboratorio qualificato allo screening; 2) di età pari o superiore a 5 anni; 3) Il paziente, i genitori del paziente o il/i tutore/i legalmente autorizzato/i devono aver firmato volontariamente un modulo di consenso informato approvato dall'Institutional Review Board/Comitato etico indipendente dopo che tutti gli aspetti rilevanti dello studio sono stati spiegati e discussi con il paziente . Il consenso dei tutori e il consenso del paziente, se del caso, devono essere ottenuti; 4) Le donne in età fertile saranno incluse solo dopo un test di gravidanza sulle urine altamente sensibile negativo.
