Yksityiskohtainen kuvaus

JNJ-73763989 on maksaan kohdistettu antiviraalinen lääke ihonalaiseen injektioon, joka on suunniteltu kroonisen hepatiitti B -viruksen (HBV) infektion hoitoon ribonukleiinihappohäiriömekanismin kautta. Tämä vaiheen 2 tutkimus on suunniteltu arvioimaan JNJ-73763989:n turvallisuutta ja tehoa HBV-infektoituneilla potilailla, joilla on samanaikaisesti HDV-infektio. Tutkimus koostuu kahdesta osasta: Osa 1 arvioi JNJ-73763989 + NA:n turvallisuutta, siedettävyyttä ja antiviraalista aktiivisuutta, kun taas osa 2 arvioi JNJ-73763989 + NA -hoidon turvallisuutta ja tehoa HBV/HDV-yhteisinfektion hoidossa. . Jokainen osa sisältää 3 vaihetta: seulontavaihe (4 viikosta enintään 8 viikkoon), interventiovaihe (144 viikkoa käsivarrelle A ja 148 viikkoa käsivarrelle B) ja seurantavaihe (48 viikkoa). Yksittäisen opiskelun kesto on 196–204 viikkoa. Turvallisuus ja siedettävyys (mukaan lukien haittatapahtumat [AE] ja vakavat haittavaikutukset, laboratorioarvioinnit, EKG [EKG], elintoiminnot, fyysinen tutkimus), teho (mukaan lukien HDV ribonukleiinihappo [RNA], HBV deoksiribonukleiinihappo [DNA] ja antigeenit) ja farmakokinetiikkaa arvioidaan koko tutkimuksen ajan.

Percentage of participants with HDV relapse post end of JNJ-3989 treatment was reported. Off-treatment HDV relapse is defined as: 1. In participants with HDV RNA <LLOQ (i.e., 630 IU/ml) at EOT: Confirmed increase in HDV RNA of > 1 log10 IU/mL above the LLOQ JNJ-3989 off-treatment. 2. In participants with HDV RNA >LLOQ at EOT: Confirmed increase in HDV RNA of > 1 log10 IU/mL from EOT HDV RNA value JNJ-3989 off-treatment.
JNJ-73763989 (JNJ-3989) + Nucleos(t)Ide Analog (NA): Post end of treatment (Week 144) up to FU Week 48; Placebo + NA: Post end of treatment (Week 148) up to FU Week 48
Parts 1 and 2: Percentage of Participants With Sustained HBV Response Off-treatment Post End of JNJ-3989 Treatment
Aikaikkuna: JNJ-73763989 (JNJ-3989) + Nucleos(t)Ide Analog (NA): Post end of treatment (Week 144) up to FU Week 48; Placebo + NA: Post end of treatment (Week 148) up to FU Week 48
Percentage of participants with sustained HBV response off-treatment post end of JNJ-3989 treatment was reported.
JNJ-73763989 (JNJ-3989) + Nucleos(t)Ide Analog (NA): Post end of treatment (Week 144) up to FU Week 48; Placebo + NA: Post end of treatment (Week 148) up to FU Week 48
Part 1: Percentage of Participants With HBV Flare (Virologic, Biochemical, and Clinical) Post End of Treatment
Aikaikkuna: JNJ-73763989 (JNJ-3989) + Nucleos(t)Ide Analog (NA): Post end of treatment (Week 144) up to FU Week 48; Placebo + NA: Post end of treatment (Week 148) up to FU Week 48
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.
JNJ-73763989 (JNJ-3989) + Nucleos(t)Ide Analog (NA): Post end of treatment (Week 144) up to FU Week 48; Placebo + NA: Post end of treatment (Week 148) up to FU Week 48
Part 2: Percentage of Participants With HBV Flare (Virologic, Biochemical, and Clinical) Post End of Treatment
Aikaikkuna: JNJ-73763989 (JNJ-3989) + Nucleos(t)Ide Analog (NA): Post end of treatment (Week 144) up to FU Week 48; Placebo + NA: Post end of treatment (Week 148) up to FU Week 48
Percentage of participants with HBV flare (Virologic, biochemical, and clinical) post end of treatment was reported 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 (Derivation 1) 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.
JNJ-73763989 (JNJ-3989) + Nucleos(t)Ide Analog (NA): Post end of treatment (Week 144) up to FU Week 48; Placebo + NA: Post end of treatment (Week 148) up to FU Week 48
