A Study to Evaluate the Effect of Hepatic Impairment on the Pharmacokinetics of Emraclidine
Study Details
Study Description
Brief Summary
The primary purpose of this study is to assess the effect of hepatic impairment on the pharmacokinetics (PK) of emraclidine following administration of a single oral dose in participants with mild, moderate, and severe hepatic impairment relative to matched participants with normal hepatic function.

Outcome Measures
Primary Outcome Measures
- Maximum Observed Plasma Concentration (Cmax) of Emraclidine [Pre-dose and at multiple timepoints post-dose up to Day 7]
- Maximum Observed Unbound Plasma Concentration (Cmax,u) of Emraclidine [Pre-dose and at multiple timepoints post-dose up to Day 7]
- Area Under the Plasma Concentration-time Curve from Time Zero to t (AUC0-t) of Emraclidine [Pre-dose and at multiple timepoints post-dose up to Day 7]
- Area Under the Unbound Plasma Concentration-time Curve from Time Zero to t (AUC0-t,u) of Emraclidine [Pre-dose and at multiple timepoints post-dose up to Day 7]
- Area Under the Plasma Concentration-time Curve from Time Zero to Infinity (AUCinf) of Emraclidine [Pre-dose and at multiple timepoints post-dose up to Day 7]
- Area Under the Unbound Plasma Concentration-time Curve From Time Zero to Infinity (AUCinf,u) of Emraclidine [Pre-dose and at multiple timepoints post-dose up to Day 7]
Secondary Outcome Measures
- Incidence and Severity of Treatment Emergent Adverse Events (TEAEs) [Day 1 up to Follow-up (Day 15)]
- Number of Participants With Clinically Significant Changes in Electrocardiogram (ECG) Values [Days 1 to 7]
- Number of Participants With Clinically Significant Changes in Vital Signs [Days 1 to 7]
- Number of Participants With Clinically Significant Changes in Laboratory Assessments [Days 1 to 7]
- Number of Participants With Clinically Significant Changes in Physical and Neurological Examination Results [Days 1 to 7]
- Changes in Columbia Suicide Severity Rating Scale (C-SSRS) Score [Days 1 to 7]
The C-SSRS includes 'yes' or 'no' responses for assessment of suicidal ideation and behavior as well as numeric ratings for severity of ideation, if present (from 1 to 5, with 5 being the most severe). Greater lethality or potential lethality of suicidal behaviors (endorsed on the behavior subscale) indicates increased risk.
Eligibility Criteria
Criteria
Key Inclusion Criteria:
- All Participants
- Male and female participants, body mass index of ≥18.0 to 42.0 kilograms per meter square (kg/m^2), inclusive, and a total body weight ≥50 kilograms (kg) (110 pounds [lbs]).
- Additional Inclusion Criteria for Participants With Normal Hepatic Function
-
Participants who are healthy, having no clinically relevant abnormalities. Have normal hepatic function.
-
Alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), bilirubin and prothrombin time ≤ upper limit of normal (ULN) and albumin ≥ lower limit of normal (LLN) and ≤ ULN. Participants with a history of Gilbert syndrome are eligible provided direct bilirubin fraction is <20% of total bilirubin, and hemoglobin, and reticulocyte counts are all ≤ ULN.
- Additional Inclusion Criteria for Participants With Hepatic Impairment - Participants with stable hepatic impairment that meets the criteria for Class A, Class B, or Class C of the modified Child-Pugh Classification. Stable hepatic disease defined as no clinically significant change in disease status in the last 28 days prior to the screening visit.
Key Exclusion Criteria:
- For All Participants
-

-
Current use of tobacco or nicotine-containing products (cigarettes, cigars, chewing tobacco, snuff, e-cigarettes, etc). Note: Light smokers (<5 cigarettes/day or equivalent) are allowed provided they abstain from the use of tobacco- or nicotine-containing products for at least 2 hours prior to PK assessments.
-

-
Type 2 second-degree or third-degree atrioventricular block
-
Heart rate <45 beats per minute (bpm) or >100 bpm
-
Abnormal ECG changes (such as clinically significant ST depression or elevation or T wave inversion).
-
Abnormal heart rhythm (such as atrial fibrillation and atrial flutter)
