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

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

20 years and older (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

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
Mean Change From Baseline in Glycosylated Hemoglobin (HbA1c) at Week 24
Time Frame: Baseline, Week 24
HbA1c analysis will be performed on a blood sample obtained by study personnel.
Baseline, Week 24

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
Mean Change From Baseline in Glycosylated Hemoglobin (HbA1c) at Week 12
Time Frame: Baseline, week 12
HbA1c analysis will be performed on a blood sample obtained by study personnel.
Baseline, week 12
Mean Change From Baseline in Fasting Plasma Glucose(FPG) at Week 12 and 24
Time Frame: Baseline, week 12, week 24
FPG analysis will be performed on a blood sample obtained by study personnel.
Baseline, week 12, week 24
Mean Change From Baseline in Postprandial Plasma Glucose(PPG) at Week 12 and 24
Time Frame: Baseline, week, week 24
PPG analysis will be performed on a blood sample obtained by study personnel.
Baseline, week, week 24
Mean Change From Baseline in Mean Amplitude of Glycemic Excursions (MAGE) Detected by Continuous Glucose Monitoring System (CGMS) After 24-week
Time Frame: Baseline, week 24
Mean amplitude of glycemic excursions (MAGE), which was used to quantify major swings of glycaemia and assess intra-day glycemic variability, was measured by inserting continuous glucose monitoring system (CGMS) in patients for 72 consecutive hours before Day 1 (Visit 2) and Week 24 (Visit 5). In order to unify the different initial time and time of completion in each patient, only the data recorded from Day 2 00:00 to Day 3 23:59 with total 48 hours were analyzed.
Baseline, week 24
The Percentage of Patients Achieving the Two Glycemic Goals After 12- and 24-week Treatment
Time Frame: week 12, week 24
Patients reaching glycemic goal of HbA1c ≤ 6.5% and ≤ 7.0% at week 12 and 24 will be calculated respectively.
week 12, week 24

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.
