The primary purpose of this study is to evaluate the plasma PK of zanzalintinib following a single dose in participants with moderate liver dysfunction compared to matched healthy participants with normal liver function.

Key Inclusion Criteria:

• All Participants:

  • No clinically significant medical history (aside from the HI for participants in the HI group only), physical examination findings, or vital signs, as deemed by the investigator.
  • A continuous non-smoker or moderate smoker who smokes ≤ 10 cigarettes, ≤ 2 cigars, or ≤2 pipes per day and agree to limit smoking during the confinement period to ≤ 4 cigarettes or ≤1 cigar or pipe per day. Participant must agree to maintain the same smoking status (smoker or non-smoker) from screening and until after the last PK sample collection.
  • Has not donated blood within 30 days of dosing or plasma within 7 days of dosing and must agree to refrain from blood donation until at least 30 days following dosing.

• Participants with Moderate HI Only:

  • Adequate bone marrow function, at the screening and dosing visit.
  • Is classified as having moderate HI by the Child-Pugh classification system (Class B, score of 7 to 9, inclusive) and has a total bilirubin value within the range of > 1.5* upper limit of normal (ULN) and ≤ 3* ULN at the screening and dosing visit.
  • Has a diagnosis of chronic (> 6 months), stable (no acute episodes of illness within the previous 2 months due to deterioration in hepatic function) hepatic insufficiency at the screening visit with features of cirrhosis due to any etiology.

• Healthy Control Participants Only:

  • Age must be within ± 10 years of the mean age of participants with moderate HI. The sex ratio (male/female ratio), and smoking status ratio (smokers/non-smokers ratio) must be the same to the sex and smoking status ratio of participants with moderate HI.

Key Exclusion Criteria:

• All Participants:

  • • History of any medical or surgical conditions that would potentially alter absorption, distribution, metabolism, and/or excretion of orally administered drugs.
  • Has or is at risk for major cardiac events or dysfunction.

• Participants with Moderate HI Only:

  • History of liver or other solid organ transplant.
  • Fluctuating or rapidly deteriorating hepatic function (the definition of the change of more than 1 Child-Pugh point) within 30 days prior to Day 1, in the opinion of the investigator and Sponsor.
  • Symptoms or history of Grade 3 or worse degree of encephalopathy within 3 months of dosing.
  • Clinical evidence of severe ascites at the screening visit or at check in.

• Healthy Control Participants Only:

  • History or presence of alcohol or drug abuse within the past 2 years prior to dosing.

Note: Other protocol defined Inclusion/Exclusion criteria may apply.
