简要总结
This study is a drug-drug interaction (DDI) investigation involving Linaprazan Glurate capsules and a combination of clarithromycin tablets, amoxicillin capsules, and bismuth potassium citrate capsules. The study plan is divided into two parts: one involving Hp-negative healthy subjects and the other involving Hp-positive subjects.
详细描述
The first part of the study is designed as a single-center, randomized, open-label, four-period, four-sequence crossover trial to evaluate the changes in pharmacokinetic (PK) profiles of Linaprazan Glurate capsules when co-administered with clarithromycin tablets and amoxicillin capsules compared to their individual administration, as well as the safety and tolerability of the combination therapy in Hp-negative healthy adult Chinese subjects.
The second part of the study is designed as a single-center, randomized, open-label, parallel-group, positive-controlled trial to compare the differences in systemic exposure of bismuth potassium citrate capsules between the Linaprazan Glurate capsule-based quadruple therapy (combined with clarithromycin tablets, amoxicillin capsules, and bismuth potassium citrate capsules) and the esomeprazole magnesium enteric-coated tablet-based quadruple therapy (combined with clarithromycin tablets, amoxicillin capsules, and bismuth potassium citrate capsules), to evaluate the pharmacodynamic effects on intragastric pH, to assess the safety and tolerability of the Linaprazan Glurate capsule-based quadruple therapy, and to preliminarily explore its efficacy in eradicating Helicobacter pylori (Hp) in Hp-positive subjects.
