Přehled studie

Detailní popis

JNJ-73763989 je antivirové léčivo cílené na játra pro subkutánní injekci určené k léčbě chronické infekce virem hepatitidy B (HBV) prostřednictvím mechanismu interference ribonukleové kyseliny. Tato studie fáze 2 je navržena tak, aby vyhodnotila bezpečnost a účinnost JNJ-73763989 u pacientů infikovaných HBV, kteří jsou současně infikováni HDV. Studie se skládá ze 2 částí: Část 1 bude hodnotit bezpečnost, snášenlivost a antivirovou aktivitu JNJ-73763989 + NA, zatímco část 2 bude hodnotit bezpečnost a účinnost režimu JNJ-73763989 + NA při léčbě koinfekce HBV/HDV . Každá část obsahuje 3 fáze: Screeningová fáze (od 4 týdnů do maximálně 8 týdnů), Intervenční fáze (144 týdnů pro rameno A a 148 týdnů pro rameno B) a Fáze sledování (48 týdnů). Délka individuální studijní účasti se bude pohybovat mezi 196 a 204 týdny. Bezpečnost a snášenlivost (včetně nežádoucích účinků [AE] a závažných AE, laboratorních vyšetření, elektrokardiogramu [EKG], vitálních funkcí, fyzikálního vyšetření), účinnosti (včetně HDV ribonukleové kyseliny [RNA], HBV deoxyribonukleové kyseliny [DNA] a antigenů) a farmakokinetika bude hodnocena v průběhu studie.

Percentage of participants with HBV flare (Virologic, biochemical, and clinical) post end of treatment was reported. Off-treatment is defined as the time period as the periods when the participants do not receive any of the study interventions (JNJ-3989/placebo and NA). Virologic flare is for participants who are off-treatment and had HBV DNA < LLOQ at the last observed point on all study treatments, and categorized based on the confirmed (i.e., two consecutive values) peak HBV DNA above any of the three thresholds: 20000 IU/mL, 2000 IU/mL and 200 IU/mL. Biochemical HBV flare is defined as a confirmed ALT and/or AST>=3*ULN and >=3* nadir (i.e. lowest value observed up to the time point of meeting the biochemical flare criteria). An HBV clinical flare occurs either when an HBV virologic flare and off-treatment HBV biochemical flare overlap in time or when a HBV biochemical flare starts within 4 weeks following the end of an HBV virologic flare.
