Brief Summary:
The purpose of this study is to measure the penetration of TR-700 into subcutaneous adipose tissue and skeletal muscle after a single oral dose of 600 mg TR-701

Condition or disease Intervention/treatment Phase
Healthy Drug: TR-700 (active moiety) Drug: TR-701 (pro-drug) Phase 1

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).

Study Type : Interventional  (Clinical Trial)

Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: None (Open Label)

Arm Intervention/treatment
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

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