E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of the study is to evaluate the long-term safety, tolerability, and effect on intravascular hemolysis of REGN3918 in patients with paroxysmal nocturnal hemoglobinuria (PNH). |
L’obiettivo primario dello studio è valutare la sicurezza a lungo termine, la tollerabilità e l’effetto dell’emolisi intravascolare di REGN3918 in pazienti con emoglobinuria parossistica notturna (EPN). |
|
E.2.2 | Secondary objectives of the trial |
The secondary objectives of the study are: •To evaluate the long-term effect of REGN3918 on intravascular hemolysis •To assess the concentrations of total REGN3918 in serum •To evaluate the occurrence of the immunogenicity of REGN3918 |
Gli obiettivi secondari dello studio consistono nel: • Valutare l’effetto a lungo termine di REGN3918 sull’emolisi intravascolare. • Valutare le concentrazioni totali di REGN3918 nel siero. • Valutare la comparsa di immunogenicità di REGN3918. |
|
E.2.3 | Trial contains a sub-study | Yes |
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: There are optional future biomedical research and pharmacogenomic analysis sub-studies . Participants will be required to sign separate sub-study ICFs before collection of samples. The purpose of the pharmacogenomic analyses is to identify genomic associations with clinical (safety or efficacy) or biomarker response to REGN3918, the complement pathway, PNH and related complement mediated diseases, clinical outcome measures, and possible AEs.
|
Altre tipologie di sottostudi specificare il titolo, la data e la versione di ogni sottostudio con i relativi obiettivi: Ci sono sotto-studi di analisibiomediche future e farmacogenomiche facoltative . I partecipanti dovranno firmare un ICF separato per i sottostudi prima della raccolta di campioni. Lo scopo delle analisi farmacogenomiche è identificare l'associazione genomica con risposta clinica (sicurezza o efficacia) o biomarker a REGN3918, il pathway del complemento, PNH e le relative malattie mediate dal complemento, misure dell'esito clinico e possibili eventi avversi.

E.3 | Principal inclusion criteria |

E.4 | Principal exclusion criteria |
1. Significant protocol deviation(s) in the parent study based on the investigator's judgment and to the extent that these would (if continued) impact the study objectives and/or safety of the patient (for example, repetitive non-compliance with dosing by the patient) 2. Any new condition or worsening of an existing condition which, in the opinion of the investigator, would make the patient unsuitable for enrollment or could interfere with the patient participating in or completing the study Other protocol defined exclusion criteria apply |
1. Deviazioni significative del protocollo nello studio principale in base al giudizio dello sperimentatore e nella misura in cui tali effetti (se continui) avrebbero un impatto sugli obiettivi dello studio e / o sulla sicurezza del paziente (ad esempio, la non conformità ripetitiva con la somministrazione del paziente) 2. Qualsiasi nuova condizione o peggioramento di una condizione esistente che, secondo l'opinione dello sperimentatore, renderebbe il paziente inadatto all'arruolamento o potrebbe interferire con il paziente che partecipa o completa lo studio. Si applicano altri criteri di esclusione definiti dal protocollo |
