Trial overview

Official title: An Open-Label, Non-Randomized, Pharmacokinetic and Safety Study of Multiple Oral Doses of SB-480848 in Healthy Subjects and Subjects with Moderate Hepatic Impairment
Trial description: The purpose of this study is to determine any differences in pharmacokinetic parameters of darapladib when dosed to people with moderate liver disease as compared to when dosed in normal healthy volunteers.
Primary purpose:
Treatment
Trial design:
Parallel Assignment
Masking:
None (Open Label)
Allocation:
Non-randomized
Primary outcomes:

Pharmacokinetic endpoints will include darapladib AUC (0-τ), Cmax and Tmax. Metabolites pharmacokinetic parameters AUC (0-τ), Cmax and Tmax will be evaluated as data permit.

Timeframe: After 10 days of repeat dosing

Clinical safety data (spontaneous AE reporting, vital signs, nursing/physician observation, and clinical laboratory tests) will be the primary safety endpoint

Timeframe: Over 10 days of repeat dosing

Secondary outcomes:

    • a moderately hepatically impaired subject with a Child-Pugh score of 7-9.
    • Hepatically Impaired Group:
    • A positive pre-study drug/alcohol screen, except where subject has prescription for pain or anxiolytic medication that would cause positive test.
    Inclusion and exclusion criteria
    Inclusion criteria:
    • A male or female is eligible to enter and participate in this study if he/she is a healthy subject OR a moderately hepatically impaired subject with a Child-Pugh score of 7-9.
    • Age between 18 and 65 years inclusive, at the time of signing the informed consent.
    • Body mass index (BMI) within the range of 19-37kg/m2
    • Capable of giving written informed consent, which includes compliance with the requirements and restrictions listed in the consent form.
    • QTcB < 480 msec in all subjects, including those with bundle branch block at screening ECG
    • Healthy subjects only: AST, ALT, alkaline phosphatase and bilirubin less than or equal to 1.5xULN (isolated bilirubin greater than 1.5xULN is acceptable if bilirubin is fractionated and direct bilirubin less than 35%)
    Exclusion criteria:
    • Hepatically Impaired Group:
    • A positive pre-study drug/alcohol screen, except where subject has prescription for pain or anxiolytic medication that would cause positive test.
    • Subjects using any concurrent prohibited medication, and/or receiving concurrent therapy that cannot be safely discontinued and is not approved by the investigator
    • The subject has participated in a clinical trial and has received an investigational product within the following time period prior to the first dosing day in the current study: 30 days, 5 half-lives or twice the duration of the biological effect of the investigational product (whichever is longer)
    • Exposure to more than four new chemical entities within 12 months prior to the first dosing day.
    • Consumption of grapefruit or grapefruit juice > 8oz within 7 days prior to first dose of study medication.
    • Currently receiving oral or injectable strong CYP3A4 inhibitor(s)
    • Subjects with any predisposing condition including malabsorption syndromes that might interfere with the absorption, distribution, metabolism, or excretion of drugs (except for hepatic impairment) or any previous gastrointestinal (GI) surgery (except appendectomy or gall bladder removal more than three months prior to the study).
    • History of sensitivity to any of the study medications, or components thereof or a history of drug or other allergy that, in the opinion of the investigator or medical monitor, contraindicates their participation.
    • History of anaphylaxis, or anaphylactoid (resembling anaphylaxis) reactions, or severe allergic responses.
    • Subjects with fluctuating or rapidly deteriorating hepatic function. Subjects should be medically stable in the opinion of the principal investigator, evidenced by liver function tests as well as clinical signs and symptoms for 30 days before the study.
    • Subjects with advanced ascites (Grade 3) or subjects with moderate or severe encephalopathy (Grade 3 or 4) as judged by the investigator.
