This study will look at healthy volunteers and how tucatinib affects their liver enzymes. Liver enzymes can change how drugs work in the body. There are 5 parts to this study. Parts A and C are looking at how the body breaks down tucatinib when there are lower levels of certain liver enzymes. Part B is looking at how the body breaks down tucatinib when there are high levels of certain liver and stomach enzymes. Parts D and E are looking at how tucatinib could change the levels of some liver and stomach enzymes in the body. This will help us know more about how tucatinib should be given to patients.', 'detailedDescription': 'This is a fixed-sequence, drug-drug interaction study of tucatinib conducted in 5 parts in healthy subjects. Part A will evaluate the effect of the strong CYP3A4 inhibitor itraconazole on the pharmacokinetics (PK) of tucatinib. Part B will evaluate the effect of rifampin, a strong inducer of CYP3A4 and CYP2C8, on the PK of tucatinib. Part C will evaluate the effect of the strong CYP2C8 inhibitor gemfibrozil on the PK of tucatinib. Part D will evaluate the effects of tucatinib on the PK of substrate probes of the metabolizing enzymes CYP2C8 (repaglinide), CYP2C9 (tolbutamide), and CYP3A4 (midazolam). Part E will evaluate the effect of tucatinib on the PK of a substrate probe of the transporter P-gp (digoxin).
