A Study to Compare the Effect of Omadacycline Versus Moxifloxacin in Healthy Adult Volunteers

Zai Lab (Hong Kong), Ltd.24 enrolled

Overview

This is a randomized (1:1), double-blind, double-dummy, phase I study to compare the effects of Omadacycline versus Moxifloxacin on gut microbiota and the resistomes in healthy adult volunteers.The study consists of 3 phases: Screening, double-blind treatment, and follow-up. Healthy volunteers aged 18-40 years, who meet entry criteria, are randomly assigned to a treatment group using an Interactive Voice Response System/Interactive Web Response System (IxRS) and receive the first dose of the study drug.

Inclusion Criteria: 1. Sign an Informed Consent Form (ICF) prior to the commencement of any study-related procedures. 2. Chinese healthy male and female subjects aged between 18 and 40 years (inclusive). 3. Body mass index (BMI) between 18.5 and 23.9 kg/m2 (inclusive). 4. Complete the stool sample collections required during screening. Exclusion Criteria: 1. Subjects with clinically significant medical history of cardiovascular, hepatic, renal, gastrointestinal or psychiatric conditions, or any other condition as deemed by the investigators that may potentially jeopardize subject safety or impact study outcomes. 2. Subjects who have undergone any major surgery within 4 weeks prior to the first dose of study drug administration. 3. Subjects who have previously undergone gastrointestinal surgery that may affect the absorption of the study drug (eg. Intestinal resection surgery, fistula surgery). 4. During screening, subjects with positive tests for hepatitis C antibodies, hepatitis B surface antigen, or hepatitis B virus (HBV) DNA or HBV RNA, or known positive tests for human immunodeficiency virus (HIV). 5. Subjects with Fridericia-corrected QT interval (QTcF) \> 450 milliseconds (males) or \> 470 milliseconds (females); or known to have long QT syndrome; or using medications that may cause arrhythmia or prolong QT interval, and/or experiencing tachyarrhythmia. 6. Subjects with a history of irritable bowel syndrome (with or without constipation) -

Outcomes

Primary Outcomes

Changes in the types of microbial resistomes.

Metagenome will be extracted from fecal samples of ME population and subjected to second-generation high-throughput sequencing. Bioinformatics will be employed to study the changes in the types of resistance-related genes of microbiota during the drug administration process in the microbiologically evaluable population. This outcome is based on second-generation high-throughput sequencing. the outcome is to test the genes to confirm the changes in types of microbial resistors in different stages.

Time frame: 3months

Secondary Outcomes

Changes in the microbial composition

Metagenome will be extracted from fecal samples of ME population and subjected to second-generation high-throughput sequencing. Principal component analysis will be employed to study the changes in the structure of microbiota during the drug administration process in the microbiologically evaluable population. This outcome is based on the result of principal component analysis to confirm the microbial composition in different stages based on different genes.
