Enrollment: 90
Study Start Date: January 2008
Study Completion Date: May 2008
Primary Completion Date: May 2008 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: 1
Single oral dose of TR-701 given once at 200mg, 400mg, 600mg, 800mg, and 1200mg. Multiple oral doses of TR-701 given once daily for 21 days at 200mg, 300mg and 400mg.
 Drug: TR-701
TR-701 will be given as single oral doses in Cohorts 1-5 and as once daily oral doses for 21 days in cohorts 6-8.
Placebo Comparator: 2
Single oral dose of placebo given in cohorts 1-5. Multiple oral doses of placebo given once daily for 21 days in cohorts 6-8 and twice daily for 21 days in cohort 10.
 Drug: placebo
Placebo will be given once for cohorts 1-5, once daily for 21 days for cohorts 6-8, and twice daily for 21 days for cohort 10.
Active Comparator: 3
Oral doses of 600mg linezolid given twice daily for 21 days.
 Drug: linezolid
Linezolid will be given at 600 mg twice daily for 21 days in cohort 10.

Detailed Description:

This is an evaluation of TR-701 in a double-blind, placebo-controlled, randomized, single (Part A) and multiple (Part B) ascending dose safety, tolerance, and PK when administered as a capsule in normal, healthy adult volunteers. The study will be sequential between Part A and Part B (i.e., not staggered or leap frogged), with slight overlap between last cohort in Part A and first cohort in Part B.
