Registration Number
NCT03557580
Lead Sponsor

Brief Summary

The purpose of this trial is to compare the pharmacokinetic characteristics of two isosorbide -5 -mononitrate extended -release tablets 40 mg of Qilu Pharmaceutical Co., Ltd and ISMO Retard (isosorbide -5 -mononitrate extended -release tablet) 40 mg, distributed by RIEMSER Pharma GmbH.

Primary endpoints are Cmax, AUC(0-t) and AUC(0-inf). Secondary endpoints are Tmax, t1/2 and λz.

Detailed Description

Objectives: Primary Objective: To compare the pharmacokinetic characteristics of two isosorbide -5 -mononitrate extended -release tablets 40 mg of Qilu Pharmaceutical Co., Ltd, China and ISMO Retard (isosorbide -5 -mononitrate extended -release tablet) 40 mg, distributed by RIEMSER Pharma GmbH. following a single oral dose administration in healthy Chinese subjects under fed condition.

Secondary Objective: To monitor the safety profile of the subjects exposed to the Investigational Medicinal Product.

Study Design: a randomized, open label, balanced, 3-way crossover, single dose study under fed conditions.12 subjects will be randomized to one of the 3 treatment sequences. Each treatment sequence will consist of 3 periods, separated by a washout period of at least 7 days. For sequence 1, first reference drug, then test formulation 1 and test formulation 2 will be administered. The order for sequence 2 is test formulation 2, reference drug and test formulation 1. The order for sequence 3 is test formulation 1, test formulation 2 and reference drug.
