Leukemias, lymphomas, and other hematologic cancers:

Indications for BRUKINSA:

Mantle cell lymphoma (MCL) in adult patients who have received at least one prior therapy.

Adult:

Swallow whole with water. 160mg twice daily or 320mg once daily until disease progression or unacceptable toxicity. Severe hepatic impairment: 80mg twice daily. Concomitant strong CYP3A inhibitors: 80mg once daily. Concomitant moderate CYP3A inhibitors: 80mg twice daily. Dose modifications for adverse reactions: see full labeling.

Children:

Not established.

Warnings/Precautions:

Risk of serious hemorrhagic events (monitor); consider the benefit/risk of withholding treatment for 3–7 days pre- and post-surgery. Monitor for fever and infections; evaluate promptly if occurs. Consider prophylaxis for opportunistic infections in high risk patients. Monitor for cytopenias; obtain CBCs during therapy. Monitor for cardiac arrhythmias (esp. in those with cardiac risk factors, hypertension, acute infections). Risk of second primary malignancies (eg, skin cancer or other carcinomas); advise patients to use sun protection. Hepatic or severe renal impairment, or on dialysis: monitor. Embryo-fetal toxicity. Advise females and males of reproductive potential 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 ≥2 weeks after the last dose).

Pharmacologic Class:

Bruton tyrosine kinase (BTK) inhibitor.

Interactions:

Concomitant moderate or strong CYP3A inducers may reduce zanubrutinib efficacy (eg, rifampin, efavirenz); avoid use. Concomitant moderate or strong CYP3A inhibitors may increase risk of toxicities (eg, itraconazole, fluconazole, erythromycin); reduce zanubrutinib dose (see Adults). Increased risk of hemorrhage with concomitant antiplatelets or anticoagulants; monitor.

Adverse Reactions:

Neutrophil count decreased, platelet count decreased, upper respiratory tract infection, WBC count decreased, hemoglobin decreased, rash, bruising, diarrhea, cough, musculoskeletal pain, pneumonia, urinary tract infection, hematuria, fatigue, constipation, hemorrhage.
