简要总结
The purpose of this study is to examine the drug exposure and drug effects on subjects with moderate hepatic impairment after a single oral dose of bexagliflozin tablets, 20mg. The study will also evaluate how safe the study drug is and how well the study drug is tolerated in subjects with moderate hepatic impairment.
详细描述
This was a Phase 1, open-label, parallel-group study designed to assess the effect of moderate hepatic impairment on the PK and PD of orally administered bexagliflozin tablets. A total of 16 subjects comprising eight with moderate hepatic impairment (Child Pugh total score 7 to 9) and eight healthy, matched controls, were enrolled and received a single oral dose of bexagliflozin tablets, 20 mg, after an overnight fast. Food was withheld for at least 2 h after dosing. Water was allowed as desired except within 1 h of drug administration.
Blood samples were collected prior to dosing, and at 0.5, 1, 2, 3, 4, 5, 6, 8, 10, 12, 16, 24, 36, and 48 h post-dose.
The unbound fraction of bexagliflozin at 24 h post dose and at the maximum plasma concentration for each subject was determined by equilibrium dialysis.
Urine samples for PD analysis were collected for the 12 h interval preceding dosing and for the 0 - 12 h, 12 - 24 h, 24 - 36 h, and 36 - 48 h intervals following dosing.

干预措施: Bexagliflozin (Drug)
结局指标
主要结局
T1/2 (Apparent Terminal Elimination Half-life)
时间窗: Up to 48 hours
Whole venous blood samples of 6mL were collected from a peripheral vein prior to dosing and at 0.5, 1, 2, 3, 4, 5, 6, 8, 10, 12, 16, 24, 36, and 48 h after administration of bexagliflozin. The pharmacokinetic parameters were estimated from the bexagliflozin plasma concentration data for each subject by non-compartmental analysis (NCA).
Cmax (Maximum Observed Plasma Concentration)
时间窗: Up to 48 hours
Whole venous blood samples of 6mL were collected from a peripheral vein prior to dosing and at 0.5, 1, 2, 3, 4, 5, 6, 8, 10, 12, 16, 24, 36, and 48 h after administration of bexagliflozin. The pharmacokinetic parameters were estimated from the bexagliflozin plasma concentration data for each subject by non-compartmental analysis (NCA).
Tmax (Time of Maximum Observed Plasma Concentration)
时间窗: Up to 48 hours
Whole venous blood samples of 6mL were collected from a peripheral vein prior to dosing and at 0.5, 1, 2, 3, 4, 5, 6, 8, 10, 12, 16, 24, 36, and 48 h after administration of bexagliflozin. The pharmacokinetic parameters were estimated from the bexagliflozin plasma concentration data for each subject by non-compartmental analysis (NCA).
AUC0-inf (Area Under the Plasma Concentration-time Curve From Time 0 to Infinity)
时间窗: Up to 48 hours
Whole venous blood samples of 6mL were collected from a peripheral vein prior to dosing and at 0.5, 1, 2, 3, 4, 5, 6, 8, 10, 12, 16, 24, 36, and 48 h after administration of bexagliflozin. The pharmacokinetic parameters were estimated from the bexagliflozin plasma concentration data for each subject by non-compartmental analysis (NCA).
Urinary Glucose Excretion 0-48 Hours
时间窗: 0-48 hours
Pre-dose urine samples were collected from -12 to 0 h for baseline measurement of pharmacodynamic parameters. Post-dose urine samples were collected without preservative in four batches: 0 to 12 h, 12 to 24 h, 24 to 36h, and 36 to 48 h after dosing. Urine aliquots were prepared from well mixed collections for the assessment of pharmacodynamics.
