Study of Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of Single Oral Doses of JTT-252

April 29, 2015 updated by: Akros Pharma Inc.

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.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study
