Single-Dose Pharmacokinetics and Safety of Oral Lofexidine in Hepatically-Impaired Subjects

Completed · Phase 1

Conditions studied: Liver Failure

In brief

This is a Phase 1, open-label, parallel-group, single-dose study of lofexidine in 6 adult subjects with mild hepatic impairment (Child Pugh score of 5 6), 6 adult subjects with moderate hepatic impairment (Child Pugh score 7 9), 6 adult subjects with severe hepatic impairment (Child Pugh score 10 15), and 6 control subjects with normal hepatic function with mean age, body mass index (BMI), and gender distribution targeted to be similar to the impaired hepatic function cohorts.

Who can join

Age: 18 and older, up to 65. Sex: any. Healthy volunteers: accepted.

You may qualify if…

• Site will evaluate each subject for criteria in detail, which will include:
• Between ages of 18 to 65 years at enrollment with a BMI between 19 and 38 kg/m2, inclusive.
• Subject is eligible to enter the study if:
• Matched control subject: normal hepatic function and free from other clinically significant illnesses or disease, and medical history, physical examination, laboratory results, and other tests consistent with health, as determined by the Investigator.
• Subject with mild hepatic impairment: Child-Pugh hepatic dysfunction staging system score of 5-6 Points (Stage A) and medical history, physical examination, laboratory results, and other tests consistent with their hepatic impairment, as determined by the Investigator.
• Subject with moderate hepatic impairment: Child-Pugh hepatic dysfunction staging system score of 7 9 Points (Stage B) and medical history, physical examination, laboratory results, and other tests consistent with their hepatic impairment, as determined by the Investigator.
• Subject with severe hepatic impairment: Child-Pugh hepatic dysfunction staging system score of 10-15 Points (Stage C) and medical history, physical examination, laboratory results, and other tests consistent with their hepatic impairment, as determined by the Investigator.

You may not qualify if…

• Site will evaluate each subject for criteria in detail, which will include:
• The matched control subject has a history of clinically significant disease, including cardiovascular, gastrointestinal (GI), renal, hepatic, pulmonary, endocrine, hematologic, vascular, immunologic, metabolic, or collagen disease or the hepatically-impaired subject has a history of clinically significant disease including cardiovascular, GI, renal, pulmonary, endocrine, hematologic, vascular, immunologic, metabolic, or collagen disease.
• Abnormal cardiovascular exam at Screening, including any of the following:
• clinically significant abnormal ECG (e.g., second or third degree heart block, uncontrolled arrhythmia, QTcF (Fridericia's correction) interval >450 msec for males and >470 msec for females).
• heart rate <45 bpm or symptomatic bradycardia;
• systolic blood pressure <90 mmHg or symptomatic hypotension;
• blood pressure >160/100 mmHg; or
• prior history of myocardial infarction.
• Subjects with hepatic impairment will not be eligible to participate in the study if any of the following exclusion criteria also apply:
• Significant bleeding diathesis or esophageal bleeding within the last 8 weeks.
• Evidence of hepatic function deterioration within the last 4 weeks as indicated by liver transaminases, alkaline phosphatase, and gamma-glutamyl transpeptidase or a ≥50% worsening of serum bilirubin or prothrombin time.
• History of surgical portosystemic shunt.
• Prothrombin time >18 seconds.
