調査の概要
状態
詳細な説明
This is a multicenter, randomized, double-blind, placebo-controlled study, including a up to 2-week screening period, a 1-week baseline period, a 12-week treatment period and a 1-week follow-up period.
72 participants who meet the enrollment requirements will enter the baseline period, during which 7 days of CGM data will be collected. After entering the treatment period, participants will be randomly assigned to prescription ABA group, prescription ABA-matched placebo group, prescription BAB group and prescription BAB-matched placebo group in a ratio of 2:1:2:1 and receive corresponding treatment.
It is expected that an interim analysis will be conducted after 30 participants have completed 4 weeks of treatment and 4 weeks of their data is obtained. Based on the CGM data of the participants in the 4th week of treatment, the change of TIR in the 4th week compared with the baseline will be analyzed, and the IDMC will make a decision based on the results of this analysis.

Change in HbA1c Concentrations (%) From Baseline
時間枠:12 weeks
|
Change in HbA1c concentrations (%) from baseline is the numerical difference between a participant's hemoglobin A1c (HbA1c) level at a specified follow-up time point(s) and their baseline level (initial assessment before intervention). HbA1c, a glycated hemoglobin biomarker, reflects average blood glucose over 8-12 weeks. Venous blood is collected via standard phlebotomy, and HbA1c is quantified using a laboratory-certified method (e.g., high-performance liquid chromatography [HPLC] or immunoassay) for accuracy. Calculated as: Follow-up HbA1c (%) - Baseline HbA1c (%), positive values mean increased average blood glucose, negative values mean decreased. This metric evaluates intervention efficacy (e.g., medications, lifestyle modifications) for glycemic control in diabetes or prediabetes populations. |

Change in FPG (mmol/L) From Baseline
時間枠:12 weeks
|
Change in Fasting Plasma Glucose (FPG) (mmol/L) from baseline is the numerical difference between a participant's FPG level at follow-up and their baseline FPG. FPG measures plasma glucose concentration after an 8-12 hour fast, reflecting overnight glycemic control. Venous blood samples are collected via standard phlebotomy, with glucose quantified using laboratory methods (e.g., hexokinase assay). Calculated as: Follow-up FPG (mmol/L) - Baseline FPG (mmol/L), positive values indicate increased fasting glucose, negative values a decrease. This metric assesses intervention efficacy in regulating fasting glycemia, critical for diabetes management. |

Changes in TIR From Baseline
時間枠:12 weeks
|
Changes in Time in Range (TIR) from baseline refers to the difference between a participant's TIR at follow-up and their baseline TIR. TIR is the percentage of time blood glucose levels stay within a target range (typically 3.9-10.0 mmol/L [70-180 mg/dL] for most people with diabetes) over a specified period, measured via continuous glucose monitoring (CGM) devices. Calculated as: Follow-up TIR (%) - Baseline TIR (%), positive values indicate increased time in target range, negative values a decrease. This metric assesses glycemic stability and intervention effectiveness (e.g., medication adjustments, lifestyle changes) in managing blood glucose control. |

Changes in TBR From Baseline
時間枠:12 weeks
|
Changes in Time Below Range (TBR) from baseline is the difference between a participant's TBR at follow-up and their baseline TBR. TBR is the percentage of time blood glucose levels fall below a target range (e.g., <3.9 mmol/L [70 mg/dL] for adults) over a specified period, measured via continuous glucose monitoring (CGM). Calculated as: Follow-up TBR (%) - Baseline TBR (%), positive values indicate increased time below range, negative values a decrease. This metric evaluates risks of hypoglycemia and intervention impact on maintaining glucose above target levels. |

Changes in TAR From Baseline
時間枠:12 weeks
|
Changes in Time Above Range (TAR) from baseline refers to the difference between a participant's TAR at follow-up and their baseline TAR. TAR is the percentage of time blood glucose levels exceed a target range (e.g., >10.0 mmol/L [180 mg/dL] for most adults with diabetes) over a specified period, measured via continuous glucose monitoring (CGM). Calculated as: Follow-up TAR (%) - Baseline TAR (%), positive values indicate increased time above range, negative values a decrease. This metric assesses risks of hyperglycemia and intervention effectiveness in keeping glucose within target levels. |

Changes in MAGE From Baseline
時間枠:12 weeks
|
Changes in Mean Amplitude of Glycemic Excursions (MAGE) from baseline is the difference between a participant's MAGE at follow-up and their baseline MAGE. MAGE quantifies the average magnitude of significant blood glucose fluctuations (exceeding a threshold, typically 1.4 mmol/L [25 mg/dL]) over a specified period, derived from continuous glucose monitoring (CGM) data. Calculated as: Follow-up MAGE - Baseline MAGE, higher values indicate greater glycemic variability, lower values more stable glucose. This metric evaluates intervention impact on reducing glucose swings, relevant for assessing glycemic stability in diabetes management. |

Change From Baseline in Total Cholesterol (TC) at Week 12
時間枠:12 weeks
|
TTotal cholesterol (TC) was measured in venous blood samples and reported in mmol/L. Change from baseline was calculated as the TC value at Week 12 minus the baseline TC value. Negative values indicate a reduction in total cholesterol. |

Change From Baseline in Body Weight at Week 12
時間枠:12 weeks
|
Body weight was measured in kilograms. Change from baseline was calculated as body weight at Week 12 minus baseline body weight. Negative values indicate weight loss, and positive values indicate weight gain. |
