E.3 | Principal inclusion criteria |
1. Patients enrolled and treated with reparixin in the REP0110 study.
2. Patients with a functioning graft at last follow-up visit (stimulated serum C-peptide levels > 0.3 ng/mL derived from the MMTT).
3. Patients willing and able to comply with the protocol procedures for the duration of the study, including scheduled follow-up visits and examinations.
4. Patients who have given written informed consent, prior to any study-related procedure not part of normal medical care, with the understanding that consent may be withdrawn by the patient at any time without prejudice to their future medical care |
- pazienti sottoposti a trapianto intra-epatico di isole pancreatiche e trattati con reparixin nello studio REP0110.
- pazienti che avevano trapianto funzionante al momento dell’ultima visita di follow-up dello studio REP0110 (livelli di C-peptide sierico prelevati durante il test di tolleranza dopo pasto misto (MMTT) > 0.3 ng/m).
- pazienti consenzienti e in grado di soddisfare tutte le procedure dello studio, inclusa la presenza a tutte le visite programmate.
- pazienti che hanno dato il consenso informato scritto prima di essere sottoposti a qualsiasi procedura dello studio, e consci del fatto che è possibile ritirare il proprio consenso in ogni momento senza subire conseguenze per la loro assistenza sanitaria futura.
