NCT00707954

Brief Summary

The purpose of this study is to evaluate the safety, pharmacokinetics and pharmacodynamics of TA-7284 orally administered once daily for 15 days (1 day followed by a 1 day washout period and then 14 consecutive days). Dose escalation design is utilized in this study, and dose escalation of TA-7284 will be starting with 25 mg (step 1). Subsequent doses of 100 mg (step 2), 200 mg (step 3) and 400 mg (step 4) are planned after review of the tolerance and PK of the previous step.
