A Phase 1, Randomized, Single-blind, Placebo-controlled, Dose Escalation Study to Evaluate the Safety, Tolerability, and Pharmacokinetics (PK) of Single Oral Doses of JTT-252 in Healthy Subjects (Part I); in Conjunction With an Open-label Study to Evaluate the Effect of Food on the PK of JTT-252 in Healthy Subjects (Part II); and an Open-label Study to Evaluate the Safety, Tolerability, PK and Pharmacodynamics (PD) of Single Oral Doses of JTT-252 in Type 2 Diabetic Subjects (Part III)

The purpose of this study is to evaluate the safety, tolerability, and PK of single oral
doses of JTT-252 and the effect of food on the PK of JTT-252 in healthy subjects, and to
evaluate the safety, tolerability, PK and PD of single oral doses of JTT-252 in type 2
diabetes mellitus subjects.
