Ascending Dose Pharmacokinetic (PK) and Absolute Bioavailability (BA) — IV/SAD/MAD  

Bacterial Infections Clinical Trial

Official title: A Double-Blind, Placebo-Controlled, Single & Multiple Ascending Dose, Safety, Tolerability, & PK Study of an IV Form of TR-701 Free Acid & an Open-Label, Crossover Absolute BA Determination of a TR-701 FA Tablet in Normal Healthy Adults

Status Completed

Clinical Trial 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.

Clinical Trial 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. ;
