A Study of GK Activator (2) in Patients With Type 2 Diabetes Mellitus Treated With a Stable Dose of Metformin

November 1, 2016 updated by: Hoffmann-La Roche

A Randomized Double-blind Study to Determine the Effect of GK Activator (2) on Efficacy (HbA1c), Safety, Tolerability and Pharmacokinetics in Patients With Type 2 Diabetes Mellitus Treated With a Stable Dose of Metformin.

This study will evaluate the efficacy, safety, tolerability, and pharmacokinetics of GK Activator (2) in combination with metformin, compared to that of placebo (metformin monotherapy), in patients with type 2 diabetes mellitus. Patients will continue on their stable dose of metformin and will be randomized to receive either GK Activator (2) or placebo. The anticipated time on study treatment is less than 3 months, and the target sample size is 100-500 individuals.

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.

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

30 years to 75 years (Adult, Older Adult)

What is the study measuring?

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
AEs, laboratory parameters.
Time Frame: Throughout study

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
