摘要

RO7049389, an inhibitor of hepatitis B virus (HBV) capsid assembly, is being developed for the treatment of patients with chronic HBV infection. The objectives of this first-in-human study are to assess the safety, tolerability, pharmacokinetics (PK), food effect, inhibitory effect on CYP3A, and effect on QT of RO7049389 in healthy participants. Five components, single-ascending-dose (SAD) cohorts, multiple- ascending-dose (MAD) cohorts, food effect assessment, drug-drug interaction assessment, and concentration-QT analysis were integrated in one study (five- in-one). Participants randomly received a single dose of 150 to 2,500 mg RO7049389 or placebo in SAD cohorts (n = 41), or multiple doses of 200 to 800 mg RO7049389 or placebo in MAD cohorts (n = 42). A single doses of 450 mg RO7049389 was administered under fasted and fed condition. The microdose of midazolam was administered before and after multiple dosing of RO7049389. Safety and tolerability were monitored throughout the study. Serial blood and urine samples were collected for the PK analysis. RO7049389 was safe and well tolerated in healthy participants. Absorption and elimination of RO7049389 occurred rapidly in plasma with minimal recovery in urine. Greater than dose-proportional increases in plasma exposure were observed. Exposure of RO7049389 (450 mg) increased by similar to 2-fold when administered with a high-fat meal. The inhibition effect of RO7049389 on CYP3A was weak (similar to 20%). No effect on QT interval was observed at up to a single dose of 2,500 mg. RO7049389 displayed a favorable safety, tolerability and PK profile suitable for further clinical development.
