Brief summary

The purpose of this study is to evaluate the safety, tolerability, and pharmacokinetics of single rising and multiple rising IV doses of TR-701 FA and to determine the absolute bioavailability of oral TR-701 FA following single oral and IV dose administrations in healthy adult subjects.

Detailed description

SAD/Part A. * All subjects in the Pilot Cohort will receive a single infusion of 50 mg TR-701 FA for injection in 250 cc of saline over 180 minutes. * Subjects in Cohort 1 will be randomized to receive a single infusion of placebo or 100 mg of TR-701 FA for injection in 250 or 500 cc of saline over 60 or 120 minutes. * Subjects in Cohort 2 will be randomized to receive a single infusion of placebo or 200 mg of TR-701 FA for injection in 250 or 500 cc of saline over 60 or 120 minutes. * Subjects in Cohort 3 will be randomized to receive a single infusion of placebo or 400 mg of TR-701 FA for injection in 250 or 500 cc of saline over 60 or 120 minutes. MAD/Part B * Subjects in Cohort 4 will be randomized to receive once daily infusions of placebo or 200 mg of TR-701 FA for injection in 250 cc of saline over 60 minutes for 7 days. * Subjects in Cohort 5 will be randomized to receive once daily infusions of placebo or 300 mg of TR-701 FA for injection in 250 cc of saline over 60 minutes for 7 days. BA/Part C * Subjects in Cohort 6 will receive a single 60 minute infusion of 200 mg TR-701 FA for injection in 250 cc of saline and a singe oral dose of 200 mg TR-701 FA tablet in an open-label crossover design. Venous Tolerability/Part D \- Subjects in Cohort 8 will receive once daily 60 minute infusions of 200 mg TR-701 FA for injection in 250 cc of saline for 3 days and once daily placebo infusions for 3 daysin a blinded crossover design.

Interventions

DRUGTR-701 FA for injection, 200 mg/vial

TR-701 FA for injection will be given as a single infusion at doses of 50 mg, 100 mg, 200 mg, and 400 mg in SAD/Part A (Pilot and Cohorts 1 to 3). TR-701 FA for injection will be given as once daily infusions at doses of 200 mg and 400 mg for 7 days in MAD/Part B (Cohorts 4 & 5). TR-701 FA for injection will be given once as a 200 mg IV infusion in BA/Part C (Cohort 6). TR-701 FA 200 mg will be given daily for 3 days in Venous Tolerability/Part D

DRUGTR-701 FA tablets

TR-701 FA will be given once orally as a 200 mg tablet in Part C.
