ABSTRACT
JNJ-73763989 is comprised of 2 short interfering RNAs (siRNAs), JNJ-73763976 and JNJ-73763924, that target hepatitis B virus (HBV) mRNAs for degradation, thereby inhibiting HBV replication. JNJ-56136379 is a capsid assembly modulator that inhibits HBV replication by inducing the formation of empty capsids (CAM-E). In 2 phase 1, open-label, non-randomized, single-center studies, the single-dose pharmacokinetics, safety, and tolerability of JNJ-73763989 or JNJ-56136379 were assessed in participants with moderate hepatic impairment (Child-Pugh Class B) versus participants with normal liver function. Participants in both studies received a single subcutaneous dose of JNJ-73763989 200 mg or oral JNJ-56136379 250 mg, followed by an evaluation of plasma pharmacokinetic parameters and safety assessments. Plasma exposure to JNJ-73763976, JNJ-73763924, and JNJ-56136379 was 1.3- to 1.4-, 1.8- to 2.2-, and 1.1- to 1.3-fold higher in participants with moderate hepatic impairment versus participants with normal liver function; however, these increases were not considered clinically relevant. Both drugs were well tolerated and safe, with 7 (21.9%) participants experiencing 1 or more treatment-emergent adverse events, 3 of which were related to JNJ-56136379. Overall, the plasma exposures of JNJ-73763989 and JNJ-56136379 were higher in participants with moderate hepatic impairment, but both were well tolerated. Further studies are needed to evaluate the effect of hepatic impairment under multiple-dose administration.
