November 28, 2016 updated by: First Affiliated Hospital Xi'an Jiaotong University

An Open-label，Single-arm，Sequential，Single-center Clinical Trial of the Pharmacokinetic Study of the Combination of Digoxin and Polythylene Glycol Loxenatide Injection (PEX168) in Healthy Adult Subjects

The purpose of this study is to evaluate the pharmacokinetic study of the combination of digoxin and polythylene glycol loxenatide injection (PEX168) in healthy adults，and to provide scientific basis for clinical combination of PEX168 and drugs.This study is also to evaluate the safety and tolerability of mono-digoxin or digoxin plus PEX168.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This will be an open-label, single-arm, sequential, single-center clinical trial. 16 healthy males will be admitted to the clinical facility on Day -1, the day prior to the start of dosing. The subjects will be observed in clinic twice: Day -1 to 8 and Day 37 to 44. Subjects will receive a single dose of digoxin on Day 1 followed by 5 weekly subcutaneously injected doses of PEX168 and a second single dose of digoxin on Day 38. To determine the pharmacokinetic parameters of digoxin after drug administration alone and after multiple doses of PEX168, blood and urine samples will be collected after each dose of digoxin and tested by the laboratory.The subjects will be discharged on Day 8 and Day 44. Approximately 28 days after the last discharge, the subjects will be called for a post study visit.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.
