Dose Range Finding Study of MK-0941 in Patients With Type 2 Diabetes Mellitus on Insulin (MK-0941-007 AM3 EXT1 AM1)(TERMINATED)

February 2, 2015 updated by: Merck Sharp & Dohme LLC

A Phase IIb, Multicenter, Randomized, Double-Blind, Placebo-Controlled Dose-Range Finding Clinical Trial of MK0941 in Patients With Type 2 Diabetes Mellitus With Inadequate Glycemic Control on Insulin

The purpose of this study is to test the effect of MK-0941 as add-on therapy for participants taking insulin for type 2 diabetes mellitus. The primary hypotheses of this study are that treatment with MK-0941 added to insulin will provide greater reduction in hemoglobin A1c (HbA1c) level than will placebo added to insulin at 14 weeks, and that MK-0941 will be well-tolerated at 1 or more doses that demonstrate efficacy.

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.

Detailed Description

This study is a 54-week randomized, double-blind base study with an optional 104-week extension study (MK-0941-007-11). Beginning on Week 16, participants not randomized to the maximum dose of MK-0941 could up-titrate to MK-0941 40 mg three times daily. Participants who complete the 54-week base study are eligible to enter the extension study and will remain in the treatment group to which they were assigned in the base study.

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

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures
