About
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.
Full description
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.

A history of exposure to an investigational drug within 30 days or 5 half-lives of the investigational drug prior to Day 0, whichever was longer
A history of exposure to any SGLT2 inhibitor within 3 months prior to Day 0 or participation in previous bexagliflozin clinical trials
A history of exposure to probenecid, rifampin, or any potential strong UGT1A9 inducers or inhibitors within 2 months of Day 0
A clinically significant abnormal electrocardiogram (ECG) that includes but is not limited to: heart rate < 40 or > 110 bpm, QRS> 160 ms, QTc> 480 ms (corrected by Bazett's formula), or any clinically significant arrhythmia including Mobitz type II 2nd Degree Heart block and bifascicular block
A history of human immunodeficiency virus (HIV) infection or a positive titer for HIV antibody
A history of vaccination (with the exception of the flu vaccine) within 30 days prior to Day 0
An estimated glomerular filtration rate (eGFR) < 60 mL·min-1 per 1.73 m2 as calculated by the modification of diet in renal disease study equation

If male, unwilling to refrain from donating sperm or to use appropriate birth control when engaging in sexual intercourse for the duration of the study and a period of 14 days after discharge from the clinic. Surgically sterile male subjects were eligible
If female and of childbearing potential, unwilling to use an adequate method of contraception to avoid or prevent pregnancy for the duration of the study and 14 days after discharge from the clinic. Surgically sterile (as a result of hysterectomy or bilateral oophorectomy), or postmenopausal (absence of menses greater than 12 months and age > 45 years) female subjects were eligible. All females were to have had a negative pregnancy test at Screening and at clinic admission

A history of surgical portosystemic shunt
For subjects in the healthy control group only:
For subjects in the hepatic impairment group only:
Any other serious medical condition that, in the opinion of the Investigator, would pose a significant risk to the subject or interfere with the interpretation of safety, PK, or PD data
