Primary Outcome Measures:
  • Subcutaneous tissue concentrations of TR-700 [ Time Frame: Single day ]

Enrollment: 15
Actual Study Start Date: April 4, 2008
Study Completion Date: August 12, 2008
Primary Completion Date: August 12, 2008 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Pilot study
3 subjects, open lable, microdialysis single dose.
Drug: TR-700 (active moiety)
A TR-700 solution will be locally administered via a microdialysis probe into the skeletal muscle and subcutanous tissue (just under the skin) at a concentration of approximately 2 µg/mL at a flow rate of 1.5 µL/min for 60 minutes for a total maximum dose of 0.36 µg (0.18 µg per probe).
Experimental: Main Study
12 subjects, open label, single dose of 600 mg.
Drug: TR-701 (pro-drug)
Each subject enrolled in the Main study will receive a single oral dose of 600mg TR-701

Detailed Description:
This study will be conducted in two parts: a Pilot Study and a Main Study. The Pilot Study will be conducted to assess recovery of exogenously administered TR-700 (microbiologically active moiety) via microdialysis. In the Main Study, pharmacokinetics of TR-700 will be determined in both soft tissues (via microdialysis) and plasma after a single oral dose of 600 mg TR-701 (prodrug).
