A Study to Evaluate the Pharmacokinetics of Avacopan (CCX168) in Participants With Mild or Moderate Hepatic Impairment
August 15, 2023 updated by: Amgen
An Open-Label, Phase 1 Study to Evaluate the Single-dose Pharmacokinetics of Avacopan (CCX168) in Male and Female Subjects With Mild or Moderate Hepatic Impairment
The primary objective of this study will be to evaluate the pharmacokinetic properties of avacopan and its metabolite CCX168-M1 after a single oral dose of 30 mg avacopan in participants with mild or moderate hepatic impairment compared to matched healthy controls.

- Medically normal with no clinically significant illness or disease and no significant abnormal findings at the baseline physical examination;
- Participant has normal (or abnormal and clinically insignificant) laboratory values at screening. A single test repeat at the discretion of the Investigator is allowed during the screening period to determine eligibility;
- Negative result from the HIV screen, the hepatitis B screen, and the hepatitis C screen.
Exclusion Criteria:
- Pregnant or breastfeeding;

- History or presence of unexplained syncope or family history of sudden death, or any medical condition or disease which, in the opinion of the Investigator, may place the participant at unacceptable risk for study participation;

- Participant has any evidence of renal impairment; serum creatinine greater than 1.5 times the upper limit of normal at screening or check-in;
- Participant's urine tested positive at screening and/or check-in for any of the following (unless the positive drug screen in hepatic participants is due to prescription drug use and is approved by the investigator and the Sponsor's Medical Monitor): opioids, amphetamines and methamphetamines, cannabinoids, benzodiazepines, barbiturates, cocaine, cotinine (healthy participants only), methylenedioxymethamphetamine (MDMA or "ecstasy"), methadone, phencyclidine, tri-cyclic antidepressants, or alcohol;

Plan for Individual participant data (IPD)
Plan to Share Individual Participant Data (IPD)?
YES
IPD Plan Description
De-identified individual patient data for variables necessary to address the specific research question in an approved data sharing request.
IPD Sharing Time Frame
Data sharing requests relating to this study will be considered beginning 18 months after the study has ended and either 1) the product and indication have been granted marketing authorization in both the US and Europe or 2) clinical development for the product and/or indication discontinues and the data will not be submitted to regulatory authorities.
There is no end date for eligibility to submit a data sharing request for this study.
IPD Sharing Access Criteria
Qualified researchers may submit a request containing the research objectives, the Amgen product(s) and Amgen study/studies in scope, endpoints/outcomes of interest, statistical analysis plan, data requirements, publication plan, and qualifications of the researcher(s).
In general, Amgen does not grant external requests for individual patient data for the purpose of re-evaluating safety and efficacy issues already addressed in the product labelling.
Requests are reviewed by a committee of internal advisors.
If not approved, a Data Sharing Independent Review Panel will arbitrate and make the final decision.
Upon approval, information necessary to address the research question will be provided under the terms of a data sharing agreement.
This may include anonymized individual patient data and/or available supporting documents, containing fragments of analysis code where provided in analysis specifications.
