Safety, Pharmacokinetics and Pharmacodynamics of TA-7284 in Type 2 Diabetic Patients

March 26, 2014 updated by: Mitsubishi Tanabe Pharma Corporation

A Clinical Pharmacology Study of Multiple Doses of TA-7284 in Patients With Type 2 Diabetes Mellitus

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.
