E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The efficacy objective of the study is to determine the effect of sparsentan on proteinuria and renal function, as compared to an angiotensin receptor blocker, in patients with Immunoglobulin A Nephropathy (IgAN).
The safety objective of the study is to assess the safety and tolerability of sparsentan by double-blind monitoring of safety endpoints. |
L'obiettivo di efficacia è di determinare l’effetto di sparsentan sulla proteinuria e la funzione renale rispetto a un bloccante del recettore dell’angiotensina, in pazienti con nefropatia da immunoglobuline A (IgAN). L'obiettivo di sicurezza è di valutare la sicurezza e la tollerabilità di sparsentan mediante monitoraggio in doppio cieco degli endpoint di sicurezza.
