Solid tumors:


Solid tumors that have a neurotrophic receptor tyrosine kinase (NTRK) gene fusion without a known acquired resistance mutation, are metastatic or where surgical resection is likely to result in severe morbidity, and have no satisfactory alternative treatments or that have progressed following treatment.

Adults and Children:

Confirm presence of a NTRK gene fusion in tumor specimens. Caps and oral soln are interchangeable. Swallow caps whole. Body surface area (BSA) <1.0m2: 100mg/m2 twice daily; BSA ≥1.0m2: 100mg twice daily. Both: continue until disease progression or unacceptable toxicity. Avoid concomitant strong CYP3A4 inhibitors, if unavoidable, reduce Vitrakvi dose by 50%. Avoid concomitant strong CYP3A4 inducers; if unavoidable, double Vitrakvi dose. Concomitant moderate CYP3A4 inducers: double Vitrakvi dose. Moderate to severe hepatic impairment: reduce initial dose by 50%. Dose modifications for adverse reactions: see full labeling.

VITRAKVI ORAL SOLUTION Warnings/Precautions:

Risk of CNS effects (including cognitive impairment, mood disorders, dizziness, sleep disturbances), hepatotoxicity; withhold or permanently discontinue based on severity; adjust dose when resumed. Monitor liver tests (including ALT/AST) every 2 weeks during the first month, then monthly thereafter, and as clinically indicated. Evaluate if signs of potential skeletal fractures occur. Embryo-fetal toxicity. Advise females of reproductive potential and males (w. female partners) to use effective contraception during and for 1 week after the last dose. Pregnancy: exclude status prior to initiation. Nursing mothers: not recommended (during and for 1 week after the last dose).

Kinase inhibitor.


Potentiated by strong CYP3A4 inhibitors (eg, itraconazole, grapefruit, or grapefruit juice); adjust dose (see Adults and Children). Potentiated by moderate CYP3A4 inhibitors; monitor more frequently and reduce dose based on severity of adverse reactions. Antagonized by strong or moderate CYP3A4 inducers (eg, rifampin, St. John's wort); adjust dose (see Adults and Children). Potentiates sensitive CYP3A4 substrates (eg, midazolam); if unavoidable, monitor for adverse reactions.
