Keverprazan, a novel potassium-competitive acid blocker: Multiple oral doses safety, tolerability, pharmacokinetics, and pharmacodynamics in healthy subjects.

ABSTRACT: Keverprazan, a novel potassium-competitive acid blocker, was approved for treating acid-related diseases. This study aimed to analyze the safety, pharmacokinetics (PKs) and pharmacodynamics (PDs) of multiple doses of keverprazan. This was a randomized, positive-/placebo-controlled, phase Ic trial. Twenty-six healthy adults were randomized to receive 20 mg/day keverprazan (n = 8), 40 mg/day keverprazan (n = 8), placebo (n = 6), or 20 mg/day vonoprazan (n = 4) for 7 days. Safety, PK and PD assessments were conducted. In the keverprazan, vonoprazan, and placebo groups, adverse events (AEs) were reported in nine (56.25%), two (50.00%), and three (50.00%) subjects, respectively. AEs were mild except a moderate abdominal pain leading to withdraw. No serious AEs occurred. The plasma concentration
