  • Subjects with Hepatic Impairment:
  • Subjects must meet the criteria for mild or moderate hepatic impairment based on CP classification. Subjects will be classified at Screening based on CP score and classification will be repeated at Check-in. If the hepatic function classification for the subject is not the same at the 2 timepoints, enrollment of the subject into a hepatic category group will be based on the CP score at Screening.
  • Subjects have stable hepatic function with a diagnosis of chronic disease of > 6 months, defined as no clinically significant change in disease status within the 60 days prior to the Screening visit or 90 days prior to drug administration on Day 1 (whichever is longer), as documented by the subject's recent medical history.
  • Subjects are on a stable medication dose(s) and/or treatment regimen(s) for treatment of hepatic impairment during the 30 days preceding the first dose of IMP. Drugs known to be moderate-to-potent inhibitors or inducers of CYP3A4/5 enzyme will not be allowed. Subjects requiring medications that are moderate-to-potent inhibitors or inducers of CYP3A4/5 may have these medications discontinued for purposes of qualifying for at least 30 days prior to dosing day for this study. Adjustments may be made if deemed medically safe and also acceptable to the Sponsor and Medical Monitor.
  • Subjects with mild or moderate hepatic impairment may have medical findings consistent with their hepatic dysfunction, as determined by medical history, physical examination, 12-lead ECG, vital sign measurements, and clinical laboratory evaluations at Screening and Check-in. Subjects with abnormal findings considered not clinically significant by the Investigator will be eligible. Vital signs between the following ranges and stable (measured in a supine position after a minimum of 5 minutes supine):
  • Systolic blood pressure ≥ 90 and ≤ 160 mmHg
  • Diastolic blood pressure ≥ 50 and ≤ 95 mmHg
  • Pulse rate ≥ 45 and ≤ 100 bpm
  • Healthy Subjects with Normal Hepatic Function:
  • Subjects with no clinically significant abnormalities in liver function test results (AST, ALT, gamma-glutamyl transferase [γ-GTP], alkaline phosphatase, total bilirubin, albumin [Alb], and PT) at Screening and Check-in. In good health, determined by no clinically significant findings from medical history, physical examination, 12-lead ECG, vital signs measurements, and clinical laboratory evaluations (congenital nonhemolytic hyperbilirubinemia [eg, suspicion of Gilbert's syndrome based on total and direct bilirubin] is not acceptable) at Screening and Check-in as assessed by the Investigator. Vital signs between the following ranges and stable (measured in a supine position after a minimum of 5 minutes supine):
  • Systolic blood pressure ≥ 95 and ≤ 150 mmHg mmHg
  • Diastolic blood pressure ≥ 50 and ≤ 90 mmHg
  • Pulse rate ≥ 45 and ≤ 100 bpm

Who cannot join

About this study

Official title: A Pharmacokinetic Study of KW-6356 in Subjects With Mild and Moderate Hepatic Impairment Compared to Subjects With Normal Hepatic Function

This is an open-label, non-randomized, single-dose study to investigate the plasma PK of KW-6356 and its major metabolite, after a single oral dose of KW-6356, in subjects with mild or moderate hepatic impairment and in healthy adults

Read the detailed description

Potential subjects will be screened to assess their eligibility to enter the study within 4 weeks prior to dose administration. Eligible subjects will be admitted to the clinical research unit (CRU) before the initiation of investigational medicinal product (IMP) administration (Check-in/Day -1) and administered of KW-6356 orally on Day 1 after an 8-hour fast. Those subjects who complete all the scheduled observations/examinations and are determined to have no clinical abnormalities requiring further hospitalization by the Investigator, will be discharged from the study site on Day 4. Discharged subjects will then visit the CRU on the scheduled visit Days 5, 6, 7, 8 for PK sample collections and safety assessments on Day 12 to complete the End of Study (EOS) visit. The duration of hospitalization will be 5 days: 4 nights from Day -1 to Day 4.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing KW-6356 in people with Hepatic Impairment, run by Kyowa Kirin, Inc. at 3 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 19 inclusion and 60 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 25 Apr 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Cmax (time frame: Day 1 to Day 12). The study lists 7 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04190654.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 25 Apr 2024.
