Study type
Interventional
Description of intervention(s) / exposure
Part 3 has a double-blind, comparative, double-dummy, two cohort design. This part of the study will enroll 12 subjects in each of two cohorts (total of 24 subjects). Subjects will be screened and then randomized in parallel to receive either oral MRX-I (800mg) or oral linezolid (600mg). Both will be administered once every 12 hours for 28 days. Subjects will be confined in a Clinical Research Unit during the dosing periods and will be monitored to ensure compliance with dosing.

Outcomes
Primary outcome [1] 290807 0
Safety and tolerability as assessed through the determination and recording of the occurrence of AEs as well as by adverse changes in vital signs, ECG (e.g. QTc interval) parameters, and laboratory data.
Timepoint [1] 290807 0
From the time of signed consent through the end of study date which occurs on Day 35
Secondary outcome [1] 305338 0
To determine the pharmacokinetics of MRX-I as assessed through blood and urine collection during the study
Timepoint [1] 305338 0
Part 3: On Day 1, obtain blood for PK analyses immediately prior to the first administration of MRX-I Tablets (active, dummy, or placebo), and at 15 and 30 minutes and 1, 2, 3, 4, 6, 8, 10, 12, 18, and 24 hours after the first administration of MRX-I Tablets (active, dummy, or placebo); obtain the 24-hour sample prior to the morning administration of study drug on Day 2. On Day 20 and Day 21, obtain blood for PK analyses immediately prior to the first administration of MRX-I Tablets (active, dummy, or placebo) for that day. On Day 28, obtain blood for PK analyses immediately prior to the final administration of MRX-I Tablets (active, dummy, or placebo), and at 15 and 30 minutes and 1, 2, 3, 4, 6, 8, 10, 12, 18, 24, 36, and 48 hours after the final administration of MRX-I Tablets (active, dummy, or placebo). Urine PK samples will be timed from administration of MRX-I Tablets (active, dummy, or placebo), rather than from administration of oral linezolid. On Day 1, obtain urine for PK analysis immediately prior to the first administration of MRX-I Tablets (active, dummy, or placebo) and at 0-2, 2-4, 4-8, 8-12, and 12-24 hours after the first administration of MRX-I Tablets (active, dummy, or placebo); obtain the 12-24 hour sample prior to the morning administration of MRX-I Tablets (active, dummy, or placebo) on Day 2. On Day 28, obtain urine for PK analysis immediately prior to the final administration of MRX-I Tablets (active, dummy, or placebo) and at 0-2, 2-4, 4-8, 8-12, 12-24, and 24-36 hours after the final administration of MRX-I Tablets (active, dummy, or placebo).

Summary
Brief summary
The primary purpose of this study on healthy volunteers is to determine the safety and tolerability of MRX-I, an orally administered antibiotic. There will be three Parts to the study. Part 1 will assess the safety, tolerability and pharmacokinetics of single dose administrations of MRX-I compared with placebo. Part 2 will assess the safety, tolerability and pharmacokinetics of a 14 day administration of MRX-I compared with placebo. Part 3 will compare the safety and tolerability of a 28 day administration of MRX-I with linezolid an active comparator. (please reference ACTRN12613001206718)
