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

18 years to 80 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change from baseline in glycosylated hemoglobin (HbA1c) at study endpoint, assessed in overall study population
Time Frame: Baseline and every study visit up to 24 weeks
HbA1c analysis will be performed on a blood sample obtained by study personnel at every visit and measured by ion exchange HPLC. Study endpoint is defined as final available post- randomization assessment obtained at any visit prior to or at the start of major change in insulin use, up to final scheduled study visit (week 24 visit) inclusive.
Baseline and every study visit up to 24 weeks
Change from baseline in glycosylated hemoglobin (HbA1c) at study endpoint, assessed in Chinese study population
Time Frame: Baseline and every study visit up to 24 weeks
HbA1c analysis will be performed on a blood sample obtained by study personnel at every visit and measured by ion exchange HPLC. Study endpoint is defined as final available post- randomization assessment obtained at any visit prior to or at the start of major change in insulin use, up to final scheduled study visit (week 24 visit) inclusive.
Baseline and every study visit up to 24 weeks

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
Measure Description
Time Frame
Number of patients with adverse events, serious adverse events and death on over all population
Time Frame: 24 weeks
Adverse events are defined as any unfavorable and unintended diagnosis, symptom, sign (including an abnormal laboratory finding), syndrome or disease which either occurs during study, having been absent at baseline, or, if present at baseline, appears to worsen. Serious adverse events are any untoward medical occurrences that result in death, are life threatening, require (or prolong) hospitalization, cause persistent or significant disability/incapacity, result in congenital anomalies or birth defects, or are other conditions which in judgment of investigators represent significant hazards.
24 weeks
Change from baseline after 24 weeks of treatment in fasting plasma glucose (FPG)on overall population
Time Frame: Baseline, week 24
FPG will be performed on the blood samples collected at all every study visits from baseline to week 24.
Baseline, week 24
Percentage of patients meeting responder criteria after 24 weeks treatment on overall population
Time Frame: After 24 weeks

Responder rate will be analyzed in the following categories:

  • Endpoint HbA1c ≤ 6.5%
  • Endpoint HbA1c < 7%
  • Endpoint HbA1c <7% in patients with baseline HbA1c ≤ 8% The percentage of patients meeting each of the responder criteria as described, as well as the percentage of patients meeting any of these criteria in each treatment group will be computed
After 24 weeks
Number of patients with adverse events, serious adverse events and death on Chinese population
Time Frame: 24 weeks
Adverse events are defined as any unfavorable and unintended diagnosis, symptom, sign (including an abnormal laboratory finding), syndrome or disease which either occurs during study, having been absent at baseline, or, if present at baseline, appears to worsen. Serious adverse events are any untoward medical occurrences that result in death, are life threatening, require (or prolong) hospitalization, cause persistent or significant disability/incapacity, result in congenital anomalies or birth defects, or are other conditions which in judgment of investigators represent significant hazards.
24 weeks
Change from baseline after 24 weeks of treatment in fasting plasma glucose (FPG) on Chinese population
Time Frame: Baseline, week 24
FPG will be performed on the blood samples collected at all every study visits from baseline to week 24.
Baseline, week 24
Percentage of patients meeting responder criteria after 24 weeks treatment on Chinese population
Time Frame: After 24 weeks
Responder rate will be analyzed in the following categories: • Endpoint HbA1c ≤ 6.5% • Endpoint HbA1c < 7% • Endpoint HbA1c <7% in patients with baseline HbA1c ≤ 8% The percentage of patients meeting each of the responder criteria as described, as well as the percentage of patients meeting any of these criteria in each treatment group will be computed

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.
