研究衡量的是什么?

主要结果指标

结果测量
措施说明
大体时间
Change in Alkaline Phosphatase (ALP) From Baseline in the Double-Blind Treatment Period
大体时间:Baseline to Week 12
Serum samples were collected at scheduled visits during the double-blind treatment period. Changes in ALP over time will be analyzed using a mixed model for repeated measures (MMRM) to assess treatment group effects across study visits. Baseline was defined as the mean of all available evaluations prior to the first administration of investigational product in the DB period. Change from Baseline was calculated as post Baseline value minus Baseline value.
Baseline to Week 12

次要结果测量

结果测量
措施说明
大体时间
Percentage of Participants With Response Rates of ≥10%, ≥20%, ≥30% and ≥40% Reduction From Baseline in ALP in the Double-Blind Treatment Period
大体时间:Week 12
Responders were defined as participants achieving a ≥10%, ≥20%, ≥30%, or ≥40% reduction from baseline in serum ALP at Week 12 with non-responder imputation applied. Baseline ALP was defined as the mean of all available evaluations prior to the first administration of investigational product in the DB period. The percentage of responders were summarized by treatment group for each response threshold and compared using a Cochran Mantel Haenszel test stratified by the randomization stratification factor.
Week 12
Normalization Rates of ALP at Week 12 in the Double-Blind Treatment Period
大体时间:Week 12
Percentage of participants achieving a response in serum ALP at Week 12 was assessed using non-responder imputation. Analyses of ALP response rates and normalization rates were performed using a Cochran-Mantel-Haenszel test stratified by the randomization stratification factor.
Week 12
Normalization Rates of Biochemical Disease Markers in the Double-Blind Treatment Period
大体时间:Week 12
Percentage of participants achieving a response in biochemical disease markers including Alanine Aminotransferase (ALT), Gamma-Glutamyl Transpeptidase (GGT), Aspartate Aminotransferase (AST), Total and conjugated Bilirubin and lipid panel (cholesterol, high density lipoprotein [HDL] and low-density lipoprotein [LDL]) at Week 12 has been presented. Analyses of response rates and normalization rates were performed using a Cochran-Mantel-Haenszel test stratified by the randomization stratification factor.
Week 12
Change From Baseline in GGT, ALT and AST Levels in the Double-Blind Treatment Period
大体时间:Baseline and at Week 12
Blood samples were collected at indicated timepoint and change from Baseline in GGT, ALT and AST were analyzed using the MMRM model and results were summarized in standard International System of Units (SI) by treatment group using descriptive statistics at baseline and at each on-study evaluation. Baseline was defined as the mean of all available evaluations prior to the first administration of investigational product in the DB period. Change from baseline was calculated as post baseline value minus baseline value.
Baseline and at Week 12
Change From Baseline in Total and Conjugated Bilirubin in the Double-Blind Treatment Period
大体时间:Baseline and at Week 12
Blood samples were collected at indicated timepoints and the changes in total and conjugated bilirubin were evaluated using MMRM to assess the effects of treatment groups over time. Baseline was defined as the mean of all available evaluations prior to the first administration of investigational product in the DB period. Change from baseline was calculated as post baseline value minus baseline value.
Baseline and at Week 12
Change From Baseline in Lipid Panel in the Double-Blind Treatment Period
大体时间:Baseline and at Week 12
Blood samples were collected at indicated timepoints and the changes in lipid panel including cholesterol, HDL and LDL were evaluated using MMRM to assess the effects of treatment groups over time. Baseline was defined as the mean of all available evaluations prior to the first administration of investigational product in the DB period. Change from Baseline was calculated as post Baseline value minus Baseline value.
Baseline and at Week 12
Change From Baseline in 7 Alpha (α) Hydroxy 4 Cholesten-3 One (C4) in the Double-Blind Treatment Period
大体时间:Baseline and at Week 12
Blood samples were collected at indicated timepoints for the assessment of C4. Baseline was defined as the mean of all available evaluations prior to the first administration of investigational product. Change from Baseline was calculated as change equals post baseline value minus baseline value.
Baseline and at Week 12
Change From Baseline in Bile Acid in the Double-Blind Treatment Period
大体时间:Baseline and at Week 12
Blood samples were collected for the assessment of bile acids. Baseline was defined as the mean of all available evaluations prior to the first administration of investigational product. Change from Baseline was calculated as change equals post Baseline value minus Baseline value.
Baseline and at Week 12
