            Cautions

            Fatal and nonfatal infection (eg, bacterial, viral, or fungal) reported; 24% of patients had Grade ≥3; consider prophylaxis according to standard of care in patients who are at increased risk for opportunistic infections; cases of progressive multifocal leukoencephalopathy (PML) and Pneumocystis jirovecii pneumonia (PJP) have occurred in patients treated with this medication; monitor and evaluate for fever and infections; treat appropriately

            Treatment-emergent Grade 3 or 4 cytopenias including neutropenia (13-29%), thrombocytopenia (5-17%), and anemia (0-13%) occurred in patients with B-cell malignancies treated with ibrutinib monotherapy; monitor CBC monthly

            Fatal and serious cases of renal failure occurred; treatment-emergent increases in creatinine levels up to 1.5 x ULN occurred in 67% (MCL) and 23% (CLL) and from 1.5-3x ULN in 9% (MCL) and 4% (CLL); periodically monitor creatinine and maintain hydration

            Other malignancies (5-14%) reported including carcinomas (1-3%); the most frequent second primary malignancy was nonmelanoma skin cancer (4-11%)

            Hypertension (12% of any grade) reported with a median time to onset of 5.9 months; monitor for new onset hypertension or hypertension that is not adequately controlled after initiating ibrutinib; monitor blood pressure in patients receiving therapy; initiate or adjust anti-hypertensive medication throughout treatment as appropriate, and follow dosage modification guidelines for Grade 3 or higher hypertension

            Tumor lysis syndrome infrequently reported; assess the baseline risk (eg, high tumor burden) and take appropriate precautions; treat as appropriate

            Based on findings in animals, can cause fetal harm when administered to a pregnant woman (see Pregnancy)

            Metabolized in the liver; although no clinical trials have been completed in patients with impaired hepatic function, ibrutinib systemic exposure was ~6-fold higher in patients (N=3) with moderate hepatic impairment (Child-Pugh B) compared to healthy volunteers

            Safety has not been evaluated in patients with mild to severe hepatic impairment by Child-Pugh criteria; reduce recommended dose when administering to patients with mild or moderate hepatic impairment (Child-Pugh class A and B); monitor patients more frequently for adverse reactions

            Cardiac arrhythmias

            • Fatal and serious cardiac arrhythmias occurred; Grade ≥3 ventricular tachyarrhythmias occurred in 0.2% of patients
            • Deaths due to cardiac causes or sudden deaths reported, including in patients with and without preexisting hypertension or cardiac comorbidities; patients with cardiac comorbidities may be at greater risk of these events
            • Atrial fibrillation and flutter (4%) reported, particularly in patients with cardiac risk factors, including hypertension and diabetes mellitus, a previous history of cardiac arrhythmias, and in patients with acute infections
            • At baseline and then periodically, monitor patients clinically for cardiac arrhythmias and cardiac failure; obtain an ECG for patients who develop arrhythmic symptoms (eg, palpitations, lightheadedness, syncope, chest pain) or new-onset dyspnea, or other cardiovascular concerns
            • Manage cardiac arrhythmias and cardiac failure appropriately, and if it persists, consider the risks and benefits of treatment and follow dose modification guidelines

            Hemorrhage

            • Grade ≥3 bleeding events (eg, subdural hematoma, GI bleeding, hematuria) occur in up to 6%; bleeding events of any grade, including bruising and petechiae, occurred in ~50% of patients treated
            • Mechanism for the bleeding events is not well understood
            • Ibrutinib may increase the risk of hemorrhage in patients receiving antiplatelet or anticoagulant therapies
            • Consider the benefit-risk of withholding ibrutinib for at least 3-7 days presurgery and postsurgery depending upon surgery type and bleeding risk

            Drug interactions overview

            • Also see Drug Modifications
            • Coadministration with a strong or moderate CYP3A inhibitors may increase ibrutinib plasma concentrations and drug-related toxicities
            • Dose modifications are recommended when coadministered with posaconazole, voriconazole and moderate CYP3A inhibitors
            • Coadministration with strong CYP3A inducers may decrease ibrutinib concentrations

            • Conduct pregnancy testing in females of reproductive potential prior to initiating therapy

            Contraception

            • Females: Use effective contraception during treatment and for 1 month after the last dose
            • Males: Advise males with female partners of reproductive potential to use effective contraception during treatment and for 1 month following last dose

            Lactation

            No information regarding the presence of ibrutinib or its metabolites in human milk, the effects on the breastfed infant, or the effects on milk production; because of potential for serious adverse reactions in breastfed child, advise women not to breastfeed during treatment and for 1 week after last dose

            Pregnancy Categories

            A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.

            B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk.

            C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done.

            D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk.

            X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist.

            NA: Information not available.

            Pharmacology

            Mechanism of Action

            Bruton’s tyrosine kinase (BTK) inhibitor; forms a covalent bond with a cysteine residue in the BTK active site, leading to inhibition of BTK enzymatic activity; BTK is a signaling molecule of the B-cell antigen receptor (BCR) and cytokine receptor pathways

            BTK’s role in signaling through the B-cell surface receptors results in activation of pathways necessary for B-cell trafficking, chemotaxis, and adhesion

            Absorption

            Peak plasma time: 1-2 hr

            AUC: 953 ng•hr/mL

            Administration with food increases ibrutinib exposure ~2-fold compared with administration after overnight fasting

            Distribution

            Protein bound: 97.3%

            Vd: 683 L; 10,000 L (steady-state)

            Metabolism

            Metabolized to several metabolites primarily by cytochrome P450 CYP3A, and to a minor extent by CYP2D6

            Active metabolite: PCI-45227, is a dihydrodiol metabolite with inhibitory activity towards BTK ~15 times lower than that of ibrutinib

            Mean metabolite to parent ratio: 1:2.8

            Elimination

            Half-life: 4-6 hr

            Oral clearance: 2000 L/hr (fasted); 1000 L/hr (fed)

            IV clearance: 62 L/hr (fasted); 76 L/hr (fed)

            Excretion: 80% feces (as metabolites [1% unchanged drug]); 10% urine

Ibrutinib belongs to a class of drugs known as kinase inhibitors. It works by slowing or stopping the growth of cancer cells.Ibrutinib is also used to treat a certain problem that may occur after a stem cell transplant (chronic graft versus host disease). It works by weakening your body's defense system (immune system).
