Primarni cilj ispitivanja jeste procijeniti učinkovitost lijeka KPL-301 u usporedbi s placebom, kada se primjenjuje zajedno s 26-tjednim smanjenjem terapije kortikosteroidima, za održavanje remisije tijekom 26 tjedana u ispitanika s novim ili relapsnim/refraktornim gigantocelularnim arteritisom (GCA). |
|
E.2.2 | Secondary objectives of the trial |
The secondary objectives of the study, in subjects with new-onset and relapsing/refractory GCA, are:
a) To evaluate the effect of KPL-301 vs placebo on cumulative corticosteroid dose.
b) To evaluate the effect of KPL-301 vs placebo on health-related quality of life (HRQoL).
c) To evaluate the safety and tolerability of KPL-301.
d) To evaluate the pharmacokinetics (PK) of KPL-301. |
Sekundarni ciljevi ispitivanja, u ispitanika s novim i relapsnim/refraktornim GCA-om, su:
a) Procijeniti učinak lijeka KPL-301 u usporedbi s placebom na kumulativnu dozu kortikosteroida.
b) Procijeniti učinak lijeka KPL-301 u usporedbi s placebom na kvalitetu života povezanu sa zdravljem (HRQoL).
c) Procijeniti sigurnost i podnošljivost lijeka KPL-301.
