Brief Summary:
The pharmacokinetics of a single dose of pexidartinib will be investigated in participants with impaired hepatic function and compared with healthy control participants with normal hepatic function.

Condition or disease Intervention/treatment Phase
Moderate Hepatic Impairment Drug: Pexidartinib Early Phase 1

Detailed Description:

Pexidartinib is an orally administered tyrosine kinase inhibitor, currently approved in the US for the treatment of adult patients with symptomatic tenosynovial giant cell tumor (TGCT) associated with severe morbidity or functional limitations and not amenable to improvement with surgery.

The primary objective of this study is to determine the plasma pharmacokinetics (PK) of pexidartinib after a single oral dose of 200 mg in participants with moderate hepatic impairment (HI) as defined by National Cancer Institute Organ Dysfunction Working Group (NCI-ODWG) criteria compared to the healthy controls participants with normal hepatic function.

  • History or presence of an abnormal ECG, which, in the investigator's opinion, is clinically significant and/or a QT interval corrected for heart rate using Fridericia's formula (QTcF) ≥450 milliseconds (ms) and ≥470 ms for healthy male and female participants, respectively, and >500 ms for participants with HI at Screening
  • Consumption of alcohol-within 72 hours prior to Check-in and caffeine-containing beverages within 48 hours prior to Check-in and during confinement
  • Consumption of more than 28 units of alcohol per week for males or 14 units of alcohol per week for females, where 1 unit of alcohol equals one-half pint of beer, 4 ounces (oz) of wine, or 1 oz of spirits, or significant history of alcoholism or drug/chemical abuse within the last 2 years
  • Positive serology for HBsAg and anti-HCV (healthy participants), HAV immunoglobulin M, or anti-HIV Type 1 and Type 2 (all participants)
  • Loss of more than 450 mL blood during the 3 months before the trial (eg, as a blood donor)
