`
` INDICATIONS AND USAGE
`
` 1.1 Mantle Cell Lymphoma
`
`
` IMBRUVICA is indicated for the treatment of patients with mantle cell lymphoma (MCL) who
`
`
` have received at least one prior therapy.
`Accelerated approval was granted for this indication based on overall response rate.
`Improvements in survival or disease-related symptoms have not been established. Continued
`approval for this indication may be contingent upon verification of clinical benefit in
`
`confirmatory trials [see Clinical Studies (14.1)].
`
`
`
`Chronic Lymphocytic Leukemia
`1.2
`
`
`IMBRUVICA is indicated for the treatment of patients with chronic lymphocytic leukemia
`
`
`(CLL) who have received at least one prior therapy [see Clinical Studies (14.2)].
`
`
`
`
`Chronic Lymphocytic Leukemia with 17p deletion
`1.3
`
`
`
`IMBRUVICA is indicated for the treatment of patients with chronic lymphocytic leukemia
`
`
`(CLL) with 17p deletion [see Clinical Studies (14.2)].
`
`
`
`DOSAGE AND ADMINISTRATION
`2
`
`
`Dosing Guidelines
`2.1
`
`
`Administer IMBRUVICA orally once daily at approximately the same time each day. Swallow
`
`
`
`
`the capsules whole with water. Do not open, break, or chew the capsules.
`
`
`2.2
`Dosage
`
`
`Mantle Cell Lymphoma
`
`The recommended dose of IMBRUVICA for MCL is 560 mg (four 140 mg capsules) orally once
`
`
`daily.
`
`Chronic Lymphocytic Leukemia
`
`The recommended dose of IMBRUVICA for CLL is 420 mg (three 140 mg capsules) orally once
`
`
`
`
`daily.
`
`Dose Modifications for Adverse Reactions
`2.3
`
`
`Interrupt IMBRUVICA therapy for any Grade 3 or greater non-hematological, Grade 3 or greater
`
`
`
`neutropenia with infection or fever, or Grade 4 hematological toxicities. Once the symptoms of
`
`the toxicity have resolved to Grade 1 or baseline (recovery), IMBRUVICA therapy may be
`
`reinitiated at the starting dose. If the toxicity reoccurs, reduce dose by one capsule (140 mg per
`
`
`
`day). A second reduction of dose by 140 mg may be considered as needed. If these toxicities
`
`
`persist or recur following two dose reductions, discontinue IMBRUVICA.
`
`
`Recommended dose modifications are described below:

`
`
`
`
`Dose Modifications for Use with CYP3A Inhibitors
`2.4
`
`
`Avoid co-administration with strong or moderate CYP3A inhibitors and consider alternative
`
`agents with less CYP3A inhibition.
`Concomitant use of strong CYP3A inhibitors which would be taken chronically (e.g., ritonavir,
`
` indinavir, nelfinavir, saquinavir, boceprevir, telaprevir, nefazodone) is not recommended. For
`short-term use (treatment for 7 days or less) of strong CYP3A inhibitors (e.g., antifungals and
`
`
`
`
` antibiotics) consider interrupting IMBRUVICA therapy until the CYP3A inhibitor is no longer
` needed [see Drug Interactions (7.1)].
`
`
`
`
` Reduce IMBRUVICA dose to 140 mg if a moderate CYP3A inhibitor must be used (e.g.,
`fluconazole, darunavir, erythromycin, diltiazem, atazanavir, aprepitant, amprenavir, fosamprevir,
`
`
`
` crizotinib, imatinib, verapamil, grapefruit products and ciprofloxacin) [see Drug Interactions
`
` (7.1)].
` Patients taking concomitant strong or moderate CYP3A inhibitors should be monitored more
`
`
`
` closely for signs of IMBRUVICA toxicity.
` 2.5 Missed Dose
`
`
`
` If a dose of IMBRUVICA is not taken at the scheduled time, it can be taken as soon as possible
` on the same day with a return to the normal schedule the following day. Extra capsules of
`
`
`
`
` IMBRUVICA should not be taken to make up for the missed dose.

` WARNINGS AND PRECAUTIONS
`
` 5.1 Hemorrhage
`
`
` Grade 3 or higher bleeding events (subdural hematoma, gastrointestinal bleeding, hematuria and
`
`
`
` post procedural hemorrhage) have occurred in up to 6% of patients. Bleeding events of any
`
`Reference ID: 3600356
`
`
`
` 3
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
` grade, including bruising and petechiae, occurred in approximately half of patients treated with
`IMBRUVICA.
`
`The mechanism for the bleeding events is not well understood.
`
`
`IMBRUVICA may increase the risk of hemorrhage in patients receiving antiplatelet or
`
`
`
`
`anticoagulant therapies.
`
`Consider the benefit-risk of withholding IMBRUVICA for at least 3 to 7 days pre and post-
`
`
`surgery depending upon the type of surgery and the risk of bleeding [see Clinical Studies (14)].
`
`
`
`5.2
`Infections
`
`
`Fatal and non-fatal infections have occurred with IMBRUVICA therapy. Twenty-five percent of
`
`
`
`
`patients with MCL and 26% of patients with CLL had infections Grade 3 or greater NCI
`
`
`
`Common Terminology Criteria for Adverse Events (CTCAE) [See Adverse Reactions (6.1) and
`
`
`
`
`(6.2)]. Monitor patients for fever and infections and evaluate promptly.
`
`
`5.3
`Cytopenias
`
`
`Treatment-emergent Grade 3 or 4 cytopenias including neutropenia (range, 23 to 29%),
`
`
`
`
`
`thrombocytopenia (range, 5 to 17%), and anemia (range, 0 to 9%) occurred in patients treated
`
`
`
`
`
`
`
`
`
`
`with IMBRUVICA.
`
`Monitor complete blood counts monthly.
`5.4
`Atrial Fibrillation
`
`
`Atrial fibrillation and atrial flutter (range, 6 to 9%) have occurred in patients treated with
`
`
`
`
`
`
`IMBRUVICA, particularly in patients with cardiac risk factors, acute infections, and a previous
`
`history of atrial fibrillation. Periodically monitor patients clinically for atrial fibrillation. Patients
`
`
`who develop arrhythmic symptoms (e.g., palpitations, lightheadedness) or new onset dyspnea
`
`
`
`should have an ECG performed. If atrial fibrillation persists, consider the risks and benefits of
`
`
`IMBRUVICA treatment and dose modification [see Dosage and Administration (2.3)].
`
`
`Second Primary Malignancies
`5.5
`
`
`Other malignancies (range, 5 to 10%) including carcinomas (range, 1 to 3%) have occurred in
`
`
`
`
`
`
`patients treated with IMBRUVICA. The most frequent second primary malignancy was non-
`
`melanoma skin cancer (range, 4 to 8%).
`
`
`
`
`Embryo-Fetal Toxicity
`5.6
`
`
`Based on findings in animals, IMBRUVICA can cause fetal harm when administered to a
`
`
`
`
`pregnant woman. Ibrutinib caused malformations in rats at exposures 14 times those reported in
`patients with MCL and 20 times those reported in patients with CLL, receiving the ibrutinib dose
`
`
`
`of 560 mg per day and 420 mg per day, respectively. Reduced fetal weights were observed at
`
`
`
`
`
`lower exposures. Advise women to avoid becoming pregnant while taking IMBRUVICA. If this
`
`
`
`drug is used during pregnancy or if the patient becomes pregnant while taking this drug, the
`
`
`
`Reference ID: 3600356
`
`
`
` 4
`
`
`
`
` patient should be apprised of the potential hazard to a fetus [see Use in Specific Populations
`
` (8.1)].
`
`
`
`
`
`
`
`

` ADVERSE REACTIONS
`
` The following adverse reactions are discussed in more detail in other sections of the labeling:
`
` • Hemorrhage [see Warnings and Precautions (5.1)]
`
`
`
`
`
` Infections [see Warnings and Precautions (5.2)]
`
`
`
`
`
`•
` • Cytopenias [see Warnings and Precautions (5.3)]
`
`
`
`
`
` • Atrial Fibrillation [see Warnings and Precautions (5.4)]
`
`
`
`
`
` • Second Primary Malignancies [see Warnings and Precautions (5.5)]
`
`
`
`
`
` Because clinical trials are conducted under widely variable conditions, adverse event rates
`
` observed in clinical trials of a drug cannot be directly compared with rates of clinical trials of
`
`
`
`
` another drug and may not reflect the rates observed in practice.
` 6.1 Mantle Cell Lymphoma
`
`
` The data described below reflect exposure to IMBRUVICA in a clinical trial that included
`
`
` 111 patients with previously treated MCL treated with 560 mg daily with a median treatment
`
`
` duration of 8.3 months.
`
` The most commonly occurring adverse reactions (≥ 20%) were thrombocytopenia, diarrhea,
`
` neutropenia, anemia, fatigue, musculoskeletal pain, peripheral edema, upper respiratory tract
`
` infection, nausea, bruising, dyspnea, constipation, rash, abdominal pain, vomiting and decreased
`
`
`
` appetite (See Tables 1 and 2).
`
`The most common Grade 3 or 4 non-hematological adverse reactions (≥ 5%) were pneumonia,
`
`
`abdominal pain, atrial fibrillation, diarrhea, fatigue, and skin infections.
`
`Fatal and serious cases of renal failure have occurred with IMBRUVICA therapy. Increases in
`
`creatinine 1.5 to 3 times the upper limit of normal occurred in 9% of patients.
`
`
`
`Adverse reactions from the MCL trial (N=111) using single agent IMBRUVICA 560 mg daily

` DRUG INTERACTIONS
`
`7
`
` Ibrutinib is primarily metabolized by cytochrome P450 enzyme 3A.
`
`
` 7.1
` CYP3A Inhibitors
` In healthy volunteers, co-administration of ketoconazole, a strong CYP3A inhibitor, increased
`
`
`
` Cmax and AUC of ibrutinib by 29- and 24-fold, respectively. The highest ibrutinib dose evaluated
`
` in clinical trials was 12.5 mg/kg (actual doses of 840 – 1400 mg) given for 28 days with single
`
`
`
`
`
` dose AUC values of 1445 ± 869 ng ⋅ hr/mL which is approximately 50% greater than steady state
` exposures seen at the highest indicated dose (560 mg).
`
`
` Avoid concomitant administration of IMBRUVICA with strong or moderate inhibitors of
` CYP3A. For strong CYP3A inhibitors used short-term (e.g., antifungals and antibiotics for
`
`
` 7 days or less, e.g., ketoconazole, itraconazole, voriconazole, posaconazole, clarithromycin,
` telithromycin) consider interrupting IMBRUVICA therapy during the duration of inhibitor use.
`
`
`
`
` Avoid strong CYP3A inhibitors that are needed chronically. If a moderate CYP3A inhibitor must
` be used, reduce the IMBRUVICA dose. Patients taking concomitant strong or moderate
`
`
`
` CYP3A4 inhibitors should be monitored more closely for signs of IMBRUVICA toxicity [see
`
` Dosage and Administration (2.4)].
`
`
` Avoid grapefruit and Seville oranges during IMBRUVICA treatment, as these contain moderate
` inhibitors of CYP3A [see Dosage and Administration (2.4), and Clinical Pharmacology (12.3)].
`
`
`
` CYP3A Inducers
`
`
` 7.2
`
`
` Administration of IMBRUVICA with rifampin, a strong CYP3A inducer, decreased ibrutinib
`
`Cmax and AUC by approximately 13- and 10-fold, respectively.
`
`
`
`
`
`Avoid concomitant use of strong CYP3A inducers (e.g., carbamazepine, rifampin, phenytoin and
`
`St. John’s Wort). Consider alternative agents with less CYP3A induction [see Clinical
`Pharmacology (12.3)].

`
`
` Risk Summary
`
`
`
` Based on findings in animals, IMBRUVICA can cause fetal harm when administered to a
`
`
` pregnant woman. If IMBRUVICA is used during pregnancy or if the patient becomes pregnant
`
` while taking IMBRUVICA, the patient should be apprised of the potential hazard to the fetus.
`
`
`
`
` Animal Data
`
` Ibrutinib was administered orally to pregnant rats during the period of organogenesis at oral
` doses of 10, 40 and 80 mg/kg/day. Ibrutinib at a dose of 80 mg/kg/day was associated with
`
`
`
`
` visceral malformations (heart and major vessels) and increased post-implantation loss. The dose
` of 80 mg/kg/day in animals is approximately 14 times the exposure (AUC) in patients with MCL
`
`
`
`
` and 20 times the exposure in patients with CLL administered the dose of 560 mg daily and
` 420 mg daily, respectively. Ibrutinib at doses of 40 mg/kg/day or greater was associated with
`
`
`
`
`
` decreased fetal weights. The dose of 40 mg/kg/day in animals is approximately
`
` 6 times the exposure (AUC) in patients with MCL administered the dose of 560 mg daily.
`
`
`
` 8.3
` Nursing Mothers
` It is not known whether ibrutinib is excreted in human milk. Because many drugs are excreted in
`
`
`
`
`
` human milk and because of the potential for serious adverse reactions in nursing infants from
` IMBRUVICA, a decision should be made whether to discontinue nursing or to discontinue the
`
`
` drug, taking into account the importance of the drug to the mother.
`
`
` 8.4
` Pediatric Use
` The safety and effectiveness of IMBRUVICA in pediatric patients has not been established.
`
`
`
` 8.5 Geriatric Use
` Of the 111 patients treated for MCL, 63% were 65 years of age or older. No overall differences
`
`
`
` in effectiveness were observed between these patients and younger patients. Cardiac adverse
`events (atrial fibrillation and hypertension), infections (pneumonia and cellulitis) and
`
`
` gastrointestinal events (diarrhea and dehydration) occurred more frequently among elderly
`
` patients.
`
`
`
`
`
`
` Of the 391 patients randomized in Study 2, 61% were ≥ 65 years of age. No overall differences
`
` in effectiveness were observed between age groups. Grade 3 or higher adverse events occurred
`
`
`
`
` more frequently among elderly patients treated with IMBRUVICA (61% of patients age ≥ 65
`
`
`
`
`
` versus 51% of younger patients) [see Clinical Studies (14.2)].

`
`
` Renal Impairment
` 8.6
`
`
`Less than 1% of ibrutinib is excreted renally. Ibrutinib exposure is not altered in patients with
`
` Creatinine clearance (CLcr) > 25 mL/min. There are no data in patients with severe renal
` impairment (CLcr < 25 mL/min) or patients on dialysis [see Clinical Pharmacology (12.3)].
`
`
`
`
` 8.7 Hepatic Impairment
` Ibrutinib is metabolized in the liver and significant increases in exposure of ibrutinib are
`
`
`
` expected in patients with hepatic impairment. Patients with serum aspartate transaminase
`
`
` (AST/SGOT) or alanine transaminase (ALT/SGPT) ≥ 3.0 x upper limit of normal (ULN) were
`
`
` excluded from IMBRUVICA clinical trials. There is insufficient data to recommend a dose of
`
`
` IMBRUVICA in patients with baseline hepatic impairment [see Clinical Pharmacology (12.3)].
`
`
`
` 8.8
` Females and Males of Reproductive Potential
` Advise women to avoid becoming pregnant while taking IMBRUVICA because IMBRUVICA
`
`
` can cause fetal harm [see Use in Specific Populations (8.1)].

` CLINICAL PHARMACOLOGY
`
` 12.1 Mechanism of Action
`
`
`
`
` Ibrutinib is a small-molecule inhibitor of BTK. Ibrutinib 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. Nonclinical studies show that ibrutinib inhibits
`
`
` malignant B-cell proliferation and survival in vivo as well as cell migration and substrate
`
` adhesion in vitro.
` 12.2 Pharmacodynamics
`
`
` In patients with recurrent B-cell lymphoma > 90% occupancy of the BTK active site in
`
`
`
` peripheral blood mononuclear cells was observed up to 24 hours after ibrutinib doses of
` ≥ 2.5 mg/kg/day (≥ 175 mg/day for average weight of 70 kg).
`
`
`
`
`
` 12.3 Pharmacokinetics
` Absorption
`
`
` Ibrutinib is absorbed after oral administration with a median Tmax of 1 to 2 hours. Ibrutinib
`
`
`
`
`exposure increases with doses up to 840 mg. The steady-state AUC (mean ± standard deviation)
`
`
`
`observed in patients at 560 mg is 953 ± 705 ng⋅h/mL and in patients at 420 mg is
`
`
`
`
`680 ± 517 ng⋅h/mL. Administration with food increased ibrutinib Cmax and AUC by
`
`
`
`
`
`
`approximately 2 to 4- and 2-fold, respectively, compared with administration of ibrutinib after
`
`overnight fasting.
`
`Distribution
`Reversible binding of ibrutinib to human plasma protein in vitro was 97.3% with no
`
`concentration dependence in the range of 50 to 1000 ng/mL. The apparent volume of distribution
`
`at steady state (Vd,ss /F) is approximately 10000 L.
`
`Metabolism
`
`
`Metabolism is the main route of elimination for ibrutinib. It is metabolized to several metabolites
`
`
`
`primarily by cytochrome P450, CYP3A, and to a minor extent by CYP2D6. The active
`
`
`metabolite, PCI-45227, is a dihydrodiol metabolite with inhibitory activity towards BTK
`
`approximately 15 times lower than that of ibrutinib. The range of the mean metabolite to parent
`
`
`ratio for PCI-45227 at steady-state is 1 to 2.8.
`
`Elimination
`
`
`Apparent clearance (CL/F) is approximately 1000 L/h. The half-life of ibrutinib is 4 to 6 hours.
`
`
`Ibrutinib, mainly in the form of metabolites, is eliminated primarily via feces. After a single oral
`administration of radiolabeled [14C]-ibrutinib in healthy subjects, approximately 90% of
`
`
`radioactivity was excreted within 168 hours, with the majority (80%) excreted in the feces and
`
`Reference ID: 3600356
`
`
`
` 13
`
`
`
`
`
`
`
`
`
`
`
` less than 10% accounted for in urine. Unchanged ibrutinib accounted for approximately 1% of
`
` the radiolabeled excretion product in feces and none in urine, with the remainder of the dose
`
` being metabolites.
`
` Age
` Age (37 to 84 years) does not alter ibrutinib systemic clearance.
`
` Gender
` Gender does not alter ibrutinib systemic clearance.
`
` Renal Impairment
` Ibrutinib is not signi
