Unless otherwise specified, the pooled safety population described in the WARNINGS AND PRECAUTIONS reflects exposure to IMBRUVICA in 6 trials. IMBRUVICA was administered as a single agent at 420 mg orally once daily (475 patients), as a single agent at 560 mg orally once daily [1.3 times the recommended adult dosage (174 patients)], and in combination with other drugs at 420 mg orally once daily (827 patients) in patients with B-cell malignancies. In this pooled safety population of 1,476 patients, 87% were exposed for 6 months or longer and 68% were exposed for greater than one year. The most common adverse reactions (≥ 30%) were thrombocytopenia, diarrhea, fatigue, musculoskeletal pain, neutropenia, rash, anemia, bruising, and nausea. Certain subsections in the WARNINGS AND PRECAUTIONS include patients who received IMBRUVICA in unapproved monotherapy or combination regimens. Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma The data described below reflect exposure to IMBRUVICA in one single-arm, open-label clinical trial (Study 1102) and five randomized controlled clinical trials (RESONATE, RESONATE-2, HELIOS, iLLUMINATE, and E1912) in patients with CLL/SLL (n=2,016 total, including n=1,133 patients exposed to IMBRUVICA). In general, patients with creatinine clearance (CLcr) ≤ 30 mL/min, AST or ALT ≥ 2.5 x ULN, or total bilirubin ≥ 1.5 x ULN (unless of non-hepatic origin) were excluded from these trials. In Study E1912, patients with AST or ALT > 3 x ULN or total bilirubin > 2.5 x ULN were excluded. Study 1102 included 51 patients with previously treated CLL/SLL. RESONATE included 386 randomized patients with previously treated CLL or SLL who received single agent IMBRUVICA or ofatumumab. RESONATE-2 included 267 randomized patients with treatment naïve CLL or SLL who were 65 years or older and received single agent IMBRUVICA or chlorambucil. HELIOS included 574 randomized patients with previously treated CLL or SLL who received IMBRUVICA in combination with BR or placebo in combination with BR. iLLUMINATE included 228 randomized patients with treatment naïve CLL/SLL who were 65 years or older or with coexisting medical conditions and received IMBRUVICA in combination with obinutuzumab or chlorambucil in combination with obinutuzumab. E1912 included 510 patients with previously untreated CLL/SLL who were 70 years or younger and received IMBRUVICA in combination with rituximab or received fludarabine, cyclophosphamide, and rituximab (FCR). The most common adverse reactions in patients with CLL/SLL receiving IMBRUVICA (≥ 30%) were thrombocytopenia, diarrhea, fatigue, musculoskeletal pain, neutropenia, rash, anemia, bruising, and nausea. Four to 10 percent of patients with CLL/SLL receiving IMBRUVICA discontinued treatment due to adverse reactions. These included pneumonia, hemorrhage, atrial fibrillation, neutropenia, arthralgia, rash, and thrombocytopenia. Adverse reactions leading to dose reduction occurred in approximately 9% of patients. Study 1102 Adverse reactions and laboratory abnormalities from Study 1102 (N=51) using single agent IMBRUVICA 420 mg daily in patients with previously treated CLL/SLL occurring at a rate of ≥ 10% with a median duration of treatment of 15.6 months are presented in Table 5 and Table 6 .

Patients age 12 years and older were treated with IMBRUVICA 420 mg orally once daily, and patients age 1 year to less than 12 years were treated with IMBRUVICA 240 mg/m 2 orally once daily [see Clinical Studies ( 14.3 )] . The median duration of exposure to IMBRUVICA was 7.1 months (range, 0.2 to 25.9 months). Serious adverse reactions occurred in 64% of patients who received IMBRUVICA. Serious adverse reactions in more than two patients included pneumonia, pyrexia, sepsis, and stomatitis. Fatal adverse reactions occurred in two patients who received IMBRUVICA, including sepsis and acute respiratory distress syndrome (ARDS). Permanent discontinuation of IMBRUVICA due to an adverse reaction occurred in 23% of patients. Adverse reactions which resulted in permanent discontinuation in at least two patients included hemorrhage. Dose reductions of IMBRUVICA due to an adverse reaction occurred in 19% of patients. Adverse reactions which required dose reduction in at least two patients included stomatitis. The most common (≥ 20%) adverse reactions, including laboratory abnormalities, were anemia, musculoskeletal pain, pyrexia, diarrhea, pneumonia, abdominal pain, stomatitis, thrombocytopenia, and headache.

Additional Important Adverse Reactions Cardiovascular Events Data on cardiovascular events are based on randomized controlled trials with IMBRUVICA (n=2,115; median treatment duration of 19.1 months for 1,157 patients treated with IMBRUVICA and 5.3 months for 958 patients in the control arm). The incidence of ventricular tachyarrhythmias (ventricular extrasystoles, ventricular arrhythmias, ventricular fibrillation, ventricular flutter, and ventricular tachycardia) of any grade was 1.0% versus 0.4% and of Grade 3 or greater was 0.3% versus 0% in patients treated with IMBRUVICA compared to patients in the control arm. The incidence of atrial fibrillation and atrial flutter of any grade was 8.4% versus 1.6% and for Grade 3 or greater was 4.0% versus 0.5% in patients treated with IMBRUVICA compared to patients in the control arm. In addition, the incidence of cardiac failure of any grade was 1.7% versus 0.5% and for Grade 3 or greater was 1.2% versus 0.3% in patients treated with IMBRUVICA compared to patients in the control arm. The incidence of ischemic cerebrovascular events (cerebrovascular accidents, ischemic stroke, cerebral ischemia, and transient ischemic attack) of any grade was 1% versus 0.4% and Grade 3 or greater was 0.5% versus 0.2% in patients treated with IMBRUVICA compared to patients in the control arm, respectively. Diarrhea In randomized controlled trials (n=2,115; median treatment duration of 19.1 months for 1,157 patients treated with IMBRUVICA and 5.3 months for 958 patients in the control arm), diarrhea of any grade occurred at a rate of 43% of patients treated with IMBRUVICA compared to 19% of patients in the control arm. Grade 3 diarrhea occurred in 3% versus 1% of IMBRUVICA-treated patients compared to the control arm, respectively. Less than 1% (0.3%) of subjects discontinued IMBRUVICA due to diarrhea compared with 0% in the control arm. Based on data from 1,605 of these patients, the median time to first onset was 21 days (range, 0 to 708) versus 46 days (range, 0 to 492) for any grade diarrhea and 117 days (range, 3 to 414) versus 194 days (range, 11 to 325) for Grade 3 diarrhea in IMBRUVICA-treated patients compared to the control arm, respectively. Of the patients who reported diarrhea, 85% versus 89% had complete resolution, and 15% versus 11% had not reported resolution at time of analysis in IMBRUVICA-treated patients compared to the control arm, respectively. The median time from onset to resolution in IMBRUVICA-treated subjects was 7 days (range, 1 to 655) versus 4 days (range, 1 to 367) for any grade diarrhea and 7 days (range, 1 to 78) versus 19 days (range, 1 to 56) for Grade 3 diarrhea in IMBRUVICA-treated subjects compared to the control arm, respectively. Visual Disturbance In randomized controlled trials (n=2,115; median treatment duration of 19.1 months for 1,157 patients treated with IMBRUVICA and 5.3 months for 958 patients in the control arm), blurred vision and decreased visual acuity of any grade occurred in 11% of patients treated with IMBRUVICA (9% Grade 1, 2% Grade 2, no Grade 3 or higher) compared to 6% in the control arm (5% Grade 1 and < 1% Grade 2 and 3). Based on data from 1,605 of these patients, the median time to first onset was 91 days (range, 0 to 617) versus 100 days (range, 2 to 477) in IMBRUVICA-treated patients compared to the control arm, respectively. Of the patients who reported visual disturbances, 60% versus 71% had complete resolution and 40% versus 29% had not reported resolution at the time of analysis in IMBRUVICA-treated patients compared to the control arm, respectively. The median time from onset to resolution was 37 days (range, 1 to 457) versus 26 days (range, 1 to 721) in IMBRUVICA-treated subjects compared to the control arm, respectively. 6.2 Postmarketing Experience The following adverse reactions have been identified during postapproval use of IMBRUVICA. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Hepatobiliary disorders: hepatic failure including acute and/or fatal events, hepatic cirrhosis Respiratory disorders: interstitial lung disease Metabolic and nutrition disorders: tumor lysis syndrome Immune system disorders: anaphylactic shock, angioedema, urticaria Skin and subcutaneous tissue disorders: Stevens-Johnson Syndrome (SJS), onychoclasis, panniculitis, neutrophilic dermatoses Infections: hepatitis B reactivation Nervous system disorders: peripheral neuropathy

10 OVERDOSAGE There is no specific experience in the management of ibrutinib overdose in patients. One healthy subject experienced reversible Grade 4 hepatic enzyme increases (AST and ALT) after a dose of 1680 mg. Closely monitor patients who ingest more than the recommended dosage and provide appropriate supportive treatment.

7 DRUG INTERACTIONS CYP3A Inhibitors: Modify IMBRUVICA dose as described ( 2.3 , 7.1 ). CYP3A Inducers: Avoid coadministration with strong CYP3A inducers ( 7.2 ). 7.1 Effect of CYP3A Inhibitors on Ibrutinib The coadministration of IMBRUVICA with a strong or moderate CYP3A inhibitor may increase ibrutinib plasma concentrations [see Clinical Pharmacology ( 12.3 )] . Increased ibrutinib concentrations may increase the risk of drug-related toxicity. Dose modifications of IMBRUVICA are recommended when used concomitantly with posaconazole, voriconazole and moderate CYP3A inhibitors [see Dosage and Administration ( 2.3 )]. Avoid concomitant use of other strong CYP3A inhibitors. Interrupt IMBRUVICA if these inhibitors will be used short-term (such as anti-infectives for seven days or less) [see Dosage and Administration ( 2.3 ) ] . Avoid grapefruit and Seville oranges during IMBRUVICA treatment, as these contain strong or moderate inhibitors of CYP3A. 7.2 Effect of CYP3A Inducers on Ibrutinib The coadministration of IMBRUVICA with strong CYP3A inducers may decrease ibrutinib concentrations. Avoid coadministration with strong CYP3A inducers [see Clinical Pharmacology ( 12.3 ) ] .

12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Ibrutinib is a small-molecule inhibitor of Bruton’s tyrosine kinase (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). In adult patients with cGVHD, 93% occupancy of the BTK active site in peripheral blood mononuclear cells was observed at the ibrutinib recommended dose. The mean BTK occupancy in pediatric patients ranged from 95.1% to 99.6%. In vitro Platelet Aggregation Ibrutinib demonstrated inhibition of collagen-induced platelet aggregation, with IC50 values at 4.6 µM (2026 ng/mL), 0.8 µM (352 ng/mL), and 3 µM (1321 ng/mL) in blood samples from healthy donors, donors taking warfarin, and donors with severe renal dysfunction, respectively. Ibrutinib did not show meaningful inhibition of platelet aggregation for ADP, arachidonic acid, ristocetin, and TRAP-6. Cardiac Electrophysiology At a single dose 4 times the maximum recommended dose (1680 mg), IMBRUVICA did not prolong the QT interval to any clinically relevant extent. 12.3 Pharmacokinetics Ibrutinib exposure increases with doses up to 840 mg (2 times the maximum approved recommended dosage) in patients with B-cell malignancies. The mean steady-state AUC (% coefficient of variation) observed in patients at 420 mg with CLL/SLL is 708 (71%) ng×h/mL, with WM is 707 (72%) ng×h/mL, and in adult patients with previously treated cGVHD is 1159 (50%) ng×h/mL. Steady-state concentrations of ibrutinib without CYP3A inhibitors were achieved with an accumulation ratio of 1 to 1.6 after 1 week of multiple daily doses of 420 mg. Absorption Absolute bioavailability of ibrutinib in fasted condition was 2.9% (90% CI: 2.1, 3.9) in healthy subjects. Ibrutinib is absorbed after oral administration with a median T max of 1 hour to 2 hours. Effect of Food The administration of IMBRUVICA with a high-fat and high-calorie meal (800 calories to 1,000 calories with approximately 50% of total caloric content of the meal from fat) increased ibrutinib C max by 2- to 4-fold and AUC by approximately 2-fold, compared with administration of ibrutinib after overnight fasting. In vitro studies suggest that ibrutinib is not a substrate of p-glycoprotein (P-gp) or breast cancer resistance protein (BCRP). Distribution Reversible binding of ibrutinib to human plasma protein in vitro was 97.3% with no concentration dependence in the range of 50 ng/mL to 1000 ng/mL. The volume of distribution (V d ) was 683 L, and the apparent volume of distribution at steady state (V d,ss /F) was approximately 10,000 L. Elimination Intravenous clearance was 62 L/h in fasted conditions and 76 L/h in fed conditions. In line with the high first-pass effect, the apparent oral clearance is 2000 L/h in fasted conditions and 1000 L/h in fed conditions. The half-life of ibrutinib is 4 hours to 6 hours. Metabolism Metabolism is the main route of elimination for ibrutinib. It is metabolized to several metabolites primarily by cytochrome P450 (CYP) 3A 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. Excretion Ibrutinib, mainly in the form of metabolites, is eliminated primarily via feces. After a single oral administration of radiolabeled ibrutinib, 90% of radioactivity was excreted within 168 hours, with 80% excreted in the feces and less than 10% eliminated in urine. Unchanged ibrutinib accounted for 1% of the radiolabeled excreted dose in feces and none in urine, with the remainder of the excreted dose being metabolites. Specific Populations Age and Sex Age and sex have no clinically meaningful effect on ibrutinib pharmacokinetics. Patients with Renal Impairment Mild and moderate renal impairment (creatinine clearance [CLcr] > 25 mL/min as estimated by Cockcroft-Gault equation) had no influence on the exposure of ibrutinib. No data is available in patients with severe renal impairment (CLcr < 25 mL/min) or in patients on dialysis. Patients with Hepatic Impairment The AUC of ibrutinib increased 2.7-fold in subjects with mild hepatic impairment (Child-Pugh class A), 8.2-fold in subjects with moderate hepatic impairment (Child-Pugh class B) and 9.8-fold in subjects with severe hepatic impairment (Child-Pugh class C) relative to subjects with normal liver function. The C max of ibrutinib increased 5.2-fold in mild hepatic impairment, 8.8-fold in moderate hepatic impairment and 7-fold in severe hepatic impairment relative to subjects with normal liver function [see Use in Specific Populations ( 8.6 )]. Pediatric Patients In pediatric patients with cGVHD treated with ibrutinib at 240 mg/m 2 once daily (patients age ≥ 1 to < 12 years) or 420 mg once daily (patients age ≥ 12 years), the geometric mean (%CV) steady state AUC and C max in patients age ≥ 1 to < 12 years is 467 (102%) ng×h/mL and 65.7 (96%) ng/mL, respectively, and in patients age ≥ 12 to < 17 years is 966 (78%) ng×h/mL and 149 (79%) ng/mL, respectively. Drug Interaction Studies Clinical Studies and Model-Informed Approaches Effect of CYP3A Inhibitors on Ibrutinib: The coadministration of multiple doses of ketoconazole (strong CYP3A inhibitor) increased the C max of ibrutinib by 29-fold and AUC by 24-fold. The coadministration of multiple doses of voriconazole (strong CYP3A inhibitor) increased steady state C max of ibrutinib by 6.7-fold and AUC by 5.7-fold. Simulations under fed conditions suggest that posaconazole (strong CYP3A inhibitor) may increase the AUC of ibrutinib 3-fold to 10-fold. The coadministration of multiple doses of erythromycin (moderate CYP3A inhibitor) increased steady state C max of ibrutinib by 3.4-fold and AUC by 3-fold. Effect of CYP3A Inducers on Ibrutinib: The coadministration of rifampin (strong CYP3A inducer) decreased the C max of ibrutinib by more than 13-fold and AUC by more than 10-fold. Simulations suggest that efavirenz (moderate CYP3A inducer) may decrease the AUC of ibrutinib by 3-fold. In Vitro Studies Effect of Ibrutinib on CYP Substrates: In vitro studies suggest that ibrutinib and PCI-45227 are unlikely to inhibit CYP1A2, 2B6, 2C8, 2C9, 2C19, 2D6 or 3A at clinical doses. Both ibrutinib and PCI-45227 are unlikely to induce CYP1A2, CYP2B6 or CYP3A at clinical doses. Effect of Ibrutinib on Substrates of Transporters: In vitro studies suggest that ibrutinib may inhibit BCRP and P-gp transport at clinical doses. The coadministration of oral P-gp or BCRP substrates (e.g., digoxin, methotrexate) with IMBRUVICA may increase their concentrations.

Metabolism Metabolism is the main route of elimination for ibrutinib. It is metabolized to several metabolites primarily by cytochrome P450 (CYP) 3A 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. Excretion Ibrutinib, mainly in the form of metabolites, is eliminated primarily via feces. After a single oral administration of radiolabeled ibrutinib, 90% of radioactivity was excreted within 168 hours, with 80% excreted in the feces and less than 10% eliminated in urine. Unchanged ibrutinib accounted for 1% of the radiolabeled excreted dose in feces and none in urine, with the remainder of the excreted dose being metabolites. Specific Populations Age and Sex Age and sex have no clinically meaningful effect on ibrutinib pharmacokinetics. Patients with Renal Impairment Mild and moderate renal impairment (creatinine clearance [CLcr] > 25 mL/min as estimated by Cockcroft-Gault equation) had no influence on the exposure of ibrutinib. No data is available in patients with severe renal impairment (CLcr < 25 mL/min) or in patients on dialysis. Patients with Hepatic Impairment The AUC of ibrutinib increased 2.7-fold in subjects with mild hepatic impairment (Child-Pugh class A), 8.2-fold in subjects with moderate hepatic impairment (Child-Pugh class B) and 9.8-fold in subjects with severe hepatic impairment (Child-Pugh class C) relative to subjects with normal liver function. The C max of ibrutinib increased 5.2-fold in mild hepatic impairment, 8.8-fold in moderate hepatic impairment and 7-fold in severe hepatic impairment relative to subjects with normal liver function [see Use in Specific Populations ( 8.6 )]. Pediatric Patients In pediatric patients with cGVHD treated with ibrutinib at 240 mg/m 2 once daily (patients age ≥ 1 to < 12 years) or 420 mg once daily (patients age ≥ 12 years), the geometric mean (%CV) steady state AUC and C max in patients age ≥ 1 to < 12 years is 467 (102%) ng×h/mL and 65.7 (96%) ng/mL, respectively, and in patients age ≥ 12 to < 17 years is 966 (78%) ng×h/mL and 149 (79%) ng/mL, respectively. Drug Interaction Studies Clinical Studies and Model-Informed Approaches Effect of CYP3A Inhibitors on Ibrutinib: The coadministration of multiple doses of ketoconazole (strong CYP3A inhibitor) increased the C max of ibrutinib by 29-fold and AUC by 24-fold. The coadministration of multiple doses of voriconazole (strong CYP3A inhibitor) increased steady state C max of ibrutinib by 6.7-fold and AUC by 5.7-fold. Simulations under fed conditions suggest that posaconazole (strong CYP3A inhibitor) may increase the AUC of ibrutinib 3-fold to 10-fold. The coadministration of multiple doses of erythromycin (moderate CYP3A inhibitor) increased steady state C max of ibrutinib by 3.4-fold and AUC by 3-fold. Effect of CYP3A Inducers on Ibrutinib: The coadministration of rifampin (strong CYP3A inducer) decreased the C max of ibrutinib by more than 13-fold and AUC by more than 10-fold. Simulations suggest that efavirenz (moderate CYP3A inducer) may decrease the AUC of ibrutinib by 3-fold. In Vitro Studies Effect of Ibrutinib on CYP Substrates: In vitro studies suggest that ibrutinib and PCI-45227 are unlikely to inhibit CYP1A2, 2B6, 2C8, 2C9, 2C19, 2D6 or 3A at clinical doses. Both ibrutinib and PCI-45227 are unlikely to induce CYP1A2, CYP2B6 or CYP3A at clinical doses. Effect of Ibrutinib on Substrates of Transporters: In vitro studies suggest that ibrutinib may inhibit BCRP and P-gp transport at clinical doses. The coadministration of oral P-gp or BCRP substrates (e.g., digoxin, methotrexate) with IMBRUVICA may increase their concentrations.

INSTRUCTIONS FOR USE IMBRUVICA (im-BRU-vih-kuh) (ibrutinib) O ral S uspension , for oral use This Instructions for Use contains information about how to prepare and give a dose of IMBRUVICA Oral Suspension . Read this Instructions for Use before you give IMBRUVICA to your child, and each time you get a refill. There may be new information. This information does not take the place of talking to your healthcare provider about your child’s medical condition or treatment. Call your healthcare provider or 1-877-877-3536 if you need help or have any questions about how to give IMBRUVICA the right way. Important information you need to know before giving IMBRUVICA to your child. IMBRUVICA is for oral use only. Give IMBRUVICA exactly as your healthcare provider tells you to. If you miss giving a dose it can be given as soon as possible on the same day. Do not give more than the prescribed dose in 1 day. If your child takes too much IMBRUVICA call your healthcare provider for help. Keep these instructions for future use. Each IMBRUVICA carton contains (see Figure A ): 1 bottle of IMBRUVICA (called ‘bottle’ in this Instructions for Use) with pre-inserted bottle adapter (called ‘adapter’ in this Instructions for Use). Do not remove the bottle adapt e r. 2 reusable 3 mL oral dosing syringes (called ‘syringe’ in this Instructions for Use) measuring in 0.1 mL increments. Only use the syringes that come with IMBRUVICA . Do not use the syringes for other patients or with other medicines. If you cannot read the markings on the syringes, throw them away and call 1-877-877-3536 to get new ones. P reparing and giving a dose of IMBRUVICA Step 1: Gather and check supplies Check your child’s prescribed dose in milliliters (mLs). Find this mL marking on the syringe. If the dose is more than the marking on the syringe, split the dose between syringes as prescribed. Gather bottle and syringe(s) (see Figure A ). Check the bottle and make sure that the bottle has IMBRUVICA Oral Suspension printed on it and the expiration date (“EXP”) has not passed . Figure A Do not use IMBRUVICA after the expiration date printed on the carton and the bottle after “EXP”. Do not use if the IMBRUVICA carton seal appears to be tampered with. Step 2: Record or check discard date When opening the bottle for the first time, record the date that is 60 days from the day the bottle is opened underneath the words “Discard Date” (see Figure B ). Use IMBRUVICA within 60 days after opening. Figure B Do not use IMBRUVICA past the discard date recorded on the bottle. Step 3: Shake bottle Shake well before each use (see Figure C ) . Figure C Step 4: Remove cap from bottle Press down and twist the cap counterclockwise to remove it from the bottle (see Figure D ). If there is fluid on top of the adapter you may wipe it with clean disposable tissue. Do not remove the bottle adapter. Figure D Step 5: Attach syringe to bottle Make sure the syringe is clean and dry before use. Push the plunger down all the way. Gently insert tip of the syringe into the adapter. Turn the assembled bottle and syringe upside down (see Figure E ). Figure E Step 6: Fill syringe Slowly pull the syringe plunger down, past the number of mLs for your prescribed dose (see Figure F ). Check for air bubbles and proceed to Step 7 for instructions on how to remove air bubbles. Figure F Step 7: Remove air bubbles and adjust to the prescribed dose (mL) Hold the syringe and tap the sides to send bubbles to the tip. With the syringe attached to the bottle, push the plunger up to remove the air bubbles from the top (see Figure G ). After the bubbles are removed, push the plunger up until the top of the colored plunger is even with the markings on the syringe for the dose. Figure G Air bubbles must be removed to ensure the correct dose. Note: Repeat steps 6 and 7 if any air bubbles remain. Step 8: Remove syringe from bottle Turn the assembled bottle upright. Hold the middle of the syringe and carefully remove it from the bottle (see Figure H ). Place the bottle aside. Figure H Do not touch the plunger of the syringe to avoid accidentally spilling the medicine before you are ready. Note: If more than 1 syringe is needed to give the full dose, repeat steps 5 to 8 with the second syringe to complete the prescribed dose. Step 9: Give IMBRUVICA Place the tip of the syringe along the inside of your child’s cheek. Slowly push the plunger all the way in to give the entire dose (see Figure I ). Repeat with second syringe if needed to complete the prescribed dose. Note: IMBRUVICA must be given as soon as possible after being drawn from the bottle. Note: Make sure your child drinks water after swallowing the dose of medicine. Figure I Step 10: Recap bottle Place the cap back on the IMBRUVICA bottle (see Figure J ). Make sure the bottle is tightly closed between each use. Figure J Step 11: Rinse syringe Remove plunger from the syringe, rinse only with water and air dry (see Figure K ). Store the syringe in a clean, dry place. Figure K Do not clean the syringe with soap or in the dishwasher. Turn over for more information How to s tore IMBRUVICA Oral Suspension Store the bottle between 36°F and 77°F (2°C and 25°C). Do not freeze. Store IMBRUVICA and all medications out of sight and reach of children. How to d ispose of IMBRUVICA Dispose of (throw away) any unused medicine within 60 days after first opening of the bottle. At the same time throw away any used or unused syringes. Ask your pharmacist how to properly dispose of the medicine. For syringe disposal, rinse and place in household trash.

Study 1102 Study 1102 (NCT01105247), an open-label, multi-center trial, was conducted in 48 previously treated CLL patients. IMBRUVICA was administered orally at 420 mg once daily until disease progression or unacceptable toxicity. The ORR and DOR were assessed using a modified version of the International Workshop on CLL Criteria by an Independent Review Committee. The median age was 67 years (range, 37 to 82 years), 71% were male, and 94% were White. All patients had a baseline ECOG performance status of 0 or 1. The median time since diagnosis was 80 months and the median number of prior treatments was 4 (range, 1 to 12 treatments). At baseline, 46% of subjects had at least one tumor ≥ 5 cm. The ORR was 58.3% (95% CI: 43.2%, 72.4%), all partial responses. None of the patients achieved a complete response. The DOR ranged from 5.6 to 24.2+ months. The median DOR was not reached. RESONATE The RESONATE study, a randomized, multicenter, open-label, phase 3 study of IMBRUVICA versus ofatumumab (NCT01578707), was conducted in patients with previously treated CLL or SLL. Patients (n=391) were randomized 1:1 to receive either IMBRUVICA 420 mg daily until disease progression, or unacceptable toxicity or ofatumumab at an initial dose of 300 mg, followed one week later by a dose of 2000 mg weekly for 7 doses and then every 4 weeks for 4 additional doses. Fifty-seven patients randomized to ofatumumab crossed over following progression to receive IMBRUVICA. The median age was 67 years (range, 30 to 88 years), 68% were male, and 90% were White. All patients had a baseline ECOG performance status of 0 or 1. The trial enrolled 373 patients with CLL and 18 patients with SLL. The median time since diagnosis was 91 months and the median number of prior treatments was 2 (range, 1 to 13 treatments). At baseline, 58% of patients had at least one tumor ≥ 5 cm. Thirty-two percent of patients had 17p deletion. Efficacy results for RESONATE are shown in Table 22 and the Kaplan-Meier curves for PFS, assessed by an IRC according to IWCLL criteria, and OS are shown in Figure 1 and Figure 2 , respectively.

Overall response rate as assessed by investigators was 87.2% in the IMBRUVICA arm versus 22.4% in the ofatumumab arm. CLL/SLL with 17p deletion (del 17p CLL/SLL) in RESONATE RESONATE included 127 patients with del 17p CLL/SLL. The median age was 67 years (range, 30 to 84 years), 62% were male, and 88% were White. All patients had a baseline ECOG performance status of 0 or 1. PFS and ORR were assessed by an IRC. Efficacy results for del 17p CLL/SLL are shown in Table 23 .

Overall response rate as assessed by investigators in patients with del 17p was 88.9% in the IMBRUVICA arm versus 18.8% in the ofatumumab arm. RESONATE-2 The RESONATE-2 study, a randomized, multicenter, open-label, phase 3 study of IMBRUVICA versus chlorambucil (NCT01722487), was conducted in patients with treatment naïve CLL or SLL who were 65 years of age or older. Patients (n = 269) were randomized 1:1 to receive either IMBRUVICA 420 mg daily until disease progression or unacceptable toxicity, or chlorambucil at a starting dose of 0.5 mg/kg on Days 1 and 15 of each 28-day cycle for a maximum of 12 cycles, with an allowance for intrapatient dose increases up to 0.8 mg/kg based on tolerability. The median age was 73 years (range, 65 to 90 years), 63% were male, and 91% were White. Ninety one percent of patients had a baseline ECOG performance status of 0 or 1 and 9% had an ECOG performance status of 2. The trial enrolled 249 patients with CLL and 20 patients with SLL. At baseline, 20% of patients had 11q deletion. The most common reasons for initiating CLL therapy include: progressive marrow failure demonstrated by anemia and/or thrombocytopenia (38%), progressive or symptomatic lymphadenopathy (37%), progressive or symptomatic splenomegaly (30%), fatigue (27%) and night sweats (25%). With a median follow-up of 28.1 months, there were 32 observed death events [11 (8.1%) and 21 (15.8%) in IMBRUVICA and chlorambucil treatment arms, respectively]. With 41% of patients switching from chlorambucil to IMBRUVICA, the overall survival analysis in the ITT patient population resulted in a statistically significant HR of 0.44 [95% CI (0.21, 0.92)] and 2-year survival rate estimates of 94.7% [95% CI (89.1, 97.4)] and 84.3% [95% CI (76.7, 89.6)] in the IMBRUVICA and chlorambucil arms, respectively. Efficacy results for RESONATE-2 are shown in Table 24 and the Kaplan-Meier curve for PFS, assessed by an IRC according to IWCLL criteria is shown in Figure 3 .

Figure 3: Kaplan-Meier Curve of Progression-Free Survival (ITT Population) in Patients with CLL/SLL in RESONATE-2 55-Month Follow-Up With an overall follow-up of 55 months, the median PFS was not reached in the IMBRUVICA arm. HELIOS The HELIOS study, a randomized, double-blind, placebo-controlled phase 3 study of IMBRUVICA in combination with bendamustine and rituximab (BR) (NCT01611090), was conducted in patients with previously treated CLL or SLL. Patients (n = 578) were randomized 1:1 to receive either IMBRUVICA 420 mg daily or placebo in combination with BR until disease progression, or unacceptable toxicity. All patients received BR for a maximum of six 28-day cycles. Bendamustine was dosed at 70 mg/m 2 infused IV over 30 minutes on Cycle 1, Days 2 and 3, and on Cycles 2-6, Days 1 and 2 for up to 6 cycles, and all patients had a CLcr ≥ 40 mL/min at baseline. Rituximab was administered at a dose of 375 mg/m 2 in the first cycle, Day 1, and 500 mg/m 2 Cycles 2 through 6, Day 1. The median age was 64 years (range, 31 to 86 years), 66% were male, and 91% were White. All patients had a baseline ECOG performance status of 0 or 1. The median time since diagnosis was 5.9 years and the median number of prior treatments was 2 (range, 1 to 11 treatments). At baseline, 56% of patients had at least one tumor > 5 cm and 26% presented with del11q. Efficacy results for HELIOS are shown in Table 25 and the Kaplan-Meier curves for PFS are shown in Figure 4 .

Figure 4: Kaplan-Meier Curve of Progression-Free Survival (ITT Population) in Patients with CLL/SLL in HELIOS iLLUMINATE The iLLUMINATE study, a randomized, multi-center, phase 3 study of IMBRUVICA in combination with obinutuzumab versus chlorambucil in combination with obinutuzumab (NCT02264574), was conducted in patients with treatment naïve CLL or SLL. Patients were 65 years of age or older or < 65 years of age with coexisting medical conditions, reduced renal function as measured by creatinine clearance < 70 mL/min, or presence of del 17p/TP53 mutation. Patients (n = 229) were randomized 1:1 to receive either IMBRUVICA 420 mg daily until disease progression or unacceptable toxicity or chlorambucil at a dose of 0.5 mg/kg on Days 1 and 15 of each 28-day cycle for 6 cycles. In both arms, patients received 1,000 mg of obinutuzumab on Days 1, 8, and 15 of the first cycle, followed by treatment on the first day of 5 subsequent cycles (total of 6 cycles, 28 days each). The first dose of obinutuzumab was divided between Day 1 (100 mg) and Day 2 (900 mg). The median age was 71 years (range, 40 to 87 years), 64% were male, and 96% were White. All patients had a baseline ECOG performance status of 0 (48%) or 1-2 (52%). The trial enrolled 214 patients with CLL and 15 patients with SLL. At baseline, 65% of patients presented with CLL/SLL with high risk factors (del 17p/TP53 mutation [18%], del 11q [15%], or unmutated immunoglobulin heavy-chain variable region (unmutated IGHV) [54%]). The most common reasons for initiating CLL therapy included: lymphadenopathy (38%), night sweats (34%), progressive marrow failure (31%), fatigue (29%), splenomegaly (25%), and progressive lymphocytosis (21%). With a median follow-up time on study of 31 months, efficacy results for iLLUMINATE assessed by an IRC according to IWCLL criteria are shown in Table 26 , and the Kaplan-Meier curve for PFS is shown in Figure 5 .

Figure 5: Kaplan-Meier Curve of Progression-Free Survival (ITT Population) in Patients with CLL/SLL in iLLUMINATE In the high risk CLL/SLL population (del 17p/TP53 mutation, del 11q, or unmutated IGHV), the PFS HR was 0.15 [95% CI (0.09, 0.27)]. E1912 The E1912 study, a randomized, multi-center, phase 3 study of IMBRUVICA in combination with rituximab versus standard fludarabine, cyclophosphamide, and rituximab (FCR) chemoimmunotherapy (NCT02048813), was conducted in adult patients who were 70 years or younger with previously untreated CLL or SLL requiring systemic therapy. All patients had a CLcr > 40 mL/min at baseline. Patients with 17p deletion were excluded. Patients (n =529) were randomized 2:1 to receive either IMBRUVICA plus rituximab or FCR. IMBRUVICA was administered at 420 mg daily until disease progression or unacceptable toxicity. Fludarabine was administered at a dose of 25 mg/m 2 , and cyclophosphamide was administered at a dose of 250 mg/m 2 , both on Days 1, 2, and 3 of Cycles 1-6. Rituximab was initiated in Cycle 2 for the IMBRUVICA plus rituximab arm and in Cycle 1 for the FCR arm and was administered at 50 mg/m 2 on Day 1 of the first cycle, 325 mg/m 2 on Day 2 of the first cycle, and 500 mg/m 2 on Day 1 of 5 subsequent cycles, for a total of 6 cycles. Each cycle was 28 days. The median age was 58 years (range, 28 to 70 years), 67% were male, 90% were White and 98% had a ECOG performance status of 0-1. At baseline, 43% of patients were Rai stage 3 or 4 and 59% of patients presented with high risk factors (TP53 mutation [6%], del11q [22%], or unmutated IGHV [53%]). With a median follow-up time on study of 37 months, efficacy results for E1912 are shown in Table 27 . The Kaplan-Meier curves for PFS, assessed according to IWCLL criteria is shown in Figure 6 .

Figure 6: Kaplan-Meier Curve of Progression-Free Survival (ITT Population) in Patients with CLL/SLL in E1912 With a median follow-up time on study of 49 months, median overall survival was not reached with a total of 23 deaths: 11 (3%) in the IMBRUVICA plus rituximab and 12 (7%) in the FCR treatment arms. Lymphocytosis Upon initiation of single-agent IMBRUVICA, an increase in lymphocyte counts (i.e., ≥ 50% increase from baseline and above absolute lymphocyte count of 5,000/mcL) occurred in 66% of patients in the CLL studies. The onset of isolated lymphocytosis occurs during the first month of IMBRUVICA therapy and resolves by a median of 14 weeks (range, 0.1 to 104 weeks). When IMBRUVICA was administered in combination, lymphocytosis was 7% with IMBRUVICA + BR versus 6% with placebo + BR and 7% with IMBRUVICA + obinutuzumab versus 1% with chlorambucil + obinutuzumab. 14. 2 Waldenström’s Macroglobulinemia The safety and efficacy of IMBRUVICA in patients with WM were demonstrated in two single-arm trials and one randomized, controlled trial. Study 1118 and INNOVATE Monotherapy Arm Study 1118 (NCT01614821), an open-label, multi-center, single-arm trial was conducted in 63 previously treated patients with WM. IMBRUVICA was administered orally at 420 mg once daily until disease progression or unacceptable toxicity. The responses were assessed by investigators and an IRC using criteria adopted from the International Workshop of Waldenström’s Macroglobulinemia. The median age was 63 years (range, 44 to 86 years), 76% were male, and 95% were White. All patients had a baseline ECOG performance status of 0 or 1. The median time since diagnosis was 74 months, and the median number of prior treatments was 2 (range, 1 to 11 treatments). At baseline, the median serum IgM value was 3.5 g/dL (range, 0.7 to 8.4 g/dL). Responses, defined as partial response or better, per IRC are shown in Table 28 . Table 28: Response Rate and Duration of Response (DOR) Based on IRC Assessment in Patients with WM in Study 1118 Total (N=63) Response rate (CR+VGPR+PR), (%) 61.9 95% CI (%) (48.8, 73.9) Complete Response (CR) 0 Very Good Partial Response (VGPR), (%) 11.1 Partial Response (PR), (%) 50.8 Median duration of response, months (range) NE (2.8+, 18.8+) CI = confidence interval; NE = not evaluable. The median time to response was 1.2 months (range, 0.7-13.4 months). The INNOVATE monotherapy arm included 31 patients with previously treated WM who failed prior rituximab-containing therapy and received single-agent IMBRUVICA. The median age was 67 years (range, 47 to 90 years). Eighty-one percent of patients had a baseline ECOG performance status of 0 or 1, and 19% had a baseline ECOG performance status of 2. The median number of prior treatments was 4 (range, 1 to 7 treatments). With an overall follow-up of 61 months, the response rate observed in the INNOVATE monotherapy arm per IRC assessment was 77% (0% CR, 29% VGPR, 48% PR). The median duration of response was 33 months (range, 2.4 to 60.2+ months). INNOVATE The INNOVATE study, a randomized, double-blind, placebo-controlled, phase 3 study of IMBRUVICA or placebo in combination with rituximab (NCT02165397), was conducted in treatment naïve or previously treated patients with WM. Patients (n = 150) were randomized 1:1 to receive either IMBRUVICA 420 mg daily or placebo in combination with rituximab until disease progression or unacceptable toxicity. Rituximab was administered weekly at a dose of 375 mg/m 2 for 4 consecutive weeks (weeks 1-4) followed by a second course of weekly rituximab for 4 consecutive weeks (weeks 17-20). The major efficacy outcome measure is progression-free survival (PFS) assessed by an IRC with additional efficacy measure of response rate. The median age was 69 years (range, 36 to 89 years), 66% were male, and 79% were White. Ninety-three percent of patients had a baseline ECOG performance status of 0 or 1, and 7% of patients had a baseline ECOG performance status of 2. Forty-five percent of patients were treatment naïve, and 55% of patients were previously treated. Among previously treated patients, the median number of prior treatments was 2 (range, 1 to 6 treatments). At baseline, the median serum IgM value was 3.2 g/dL (range, 0.6 to 8.3 g/dL), and MYD88 L265P mutations were present in 77% of patients, absent in 13% of patients, and 9% of patients were not evaluable for mutation status. An exploratory analysis demonstrated a sustained hemoglobin improvement (defined as increase of ≥ 2 g/dL over baseline for at least 8 weeks without blood transfusions or growth factor support) in 65% of patients in the IMBRUVICA + R group and 39% of patients in the placebo + R group. With an overall follow-up of 63 months, efficacy results as assessed by an IRC at the time of the final analysis for INNOVATE are shown in Table 29 , and the Kaplan-Meier curves for PFS are shown in Figure 7 . Table 29: Efficacy Results in Patients with WM by IRC in INNOVATE (Final Analysis) Endpoint IMBRUVICA + R N=75 Placebo + R N=75 Progression - Free Survival Number of events (%) 22 (29) 50 (67) Median (95% CI), months NE (57.7, NE) 20.3 (13.0, 27.6) HR (95% CI) 0.25 (0.15, 0.42) P-value a <0.0001 Response Rate (CR+VGPR+PR) b 76% 31% 95% CI (%) (65, 85) (21, 42) Complete Response (CR) 1% 1% Very Good Partial Response (VGPR) 29% 4% Partial Response (PR) 45% 25% Median duration of response, months (range) NE (1.9+, 58.9+) NE (4.6+, 49.7+) CI = confidence interval; HR = hazard ratio; NE = not evaluable; R = rituximab. a P-value is from the stratified log-rank test. b P-value associated with response rate was <0.0001. Figure 7: Kaplan-Meier Curve of Progression-Free Survival (ITT Population) in Patients with WM in INNOVATE Median overall survival was not reached for either treatment arm. With an overall follow-up of 63 months, 9 (12%) patients on IMBRUVICA + R and 10 (13.3%) patients on placebo + R had died. Forty-seven percent of patients randomized to the placebo + R arm crossed over to receive IMBRUVICA. 14. 3 Chronic Graft versus Host Disease Study 1129 The safety and efficacy of IMBRUVICA in cGVHD were evaluated in Study 1129 (NCT02195869), an open-label, multi-center, single-arm trial of 42 patients with cGVHD after failure of first line corticosteroid therapy and requiring additional therapy. IMBRUVICA was administered orally at 420 mg once daily. The responses were assessed by investigators using the 2005 National Institute of Health (NIH) Consensus Panel Response Criteria with two modifications to align with the updated 2014 NIH Consensus Panel Response Criteria. The median age was 56 years (range, 19 to 74 years), 52% were male, and 93% were White. The most common underlying malignancies leading to transplantation were acute lymphocytic leukemia, acute myeloid leukemia, and CLL. The median time since cGVHD diagnosis was 14 months, the median number of prior cGVHD treatments was 2 (range, 1 to 3 treatments), and 60% of patients had a Karnofsky performance score of ≤ 80. The majority of patients (88 %) had at least 2 organs involved at baseline, with the most commonly involved organs being mouth (86%), skin (81%), and gastrointestinal tract (33%). The median daily corticosteroid dose (prednisone or prednisone equivalent) at baseline was 0.3 mg/kg/day, and 52% of patients were receiving ongoing immunosuppressants in addition to systemic corticosteroids at baseline. Prophylaxis for infections were managed per institutional guidelines with 79% of patients receiving combinations of sulfonamides and trimethoprim and 64% receiving triazole derivatives. Efficacy results are shown in Table 30 . Table 30: Best Overall Response Rate (ORR) and Sustained Response Rate Based on Investigator Assessment a in Patients with cGVHD in Study 1129 Total (N=42) ORR 28 (67%) 95% CI (51%, 80%) Complete Response (CR) 9 (21%) Partial Response (PR) 19 (45%) Sustained response rate b 20 (48%) CI = confidence interval. a Investigator assessment based on the 2005 NIH Response Criteria with two modifications (added “not evaluable” for organs with non-cGVHD abnormalities, and organ score change from 0 to 1 was not considered disease progression.) b Sustained response rate is defined as the proportion of patients who achieved a CR or PR that was sustained for at least 20 weeks. The median time to response coinciding with the first scheduled response assessment was 12.3 weeks (range, 4.1 to 42.1 weeks). Responses were seen across all organs involved for cGVHD (skin, mouth, gastrointestinal tract, and liver). ORR results were supported by exploratory analyses of patient-reported symptom bother which showed at least a 7-point decrease in Lee Symptom Scale overall summary score in 24% (10/42) of patients on at least 2 consecutive visits. iMAGINE The safety and efficacy of IMBRUVICA were evaluated in iMAGINE (NCT03790332), an open-label, multi-center, single-arm trial of IMBRUVICA for the treatment of pediatric and young adult patients age 1 year to less than 22 years with moderate or severe cGVHD as defined by NIH Consensus Criteria. The study included 47 patients who required additional therapy after failure of one or more prior lines of systemic therapy. All patients had platelets ≥ 30 x 10 9 /L; absolute neutrophil count ≥ 1.0 x 10 9 /L; AST or ALT ≤ 3 x ULN; total bilirubin of ≤ 1.5 x ULN; and estimated creatinine clearance ≥ 30 mL/min. Patients were excluded if single organ genitourinary involvement was the only manifestation of cGVHD. Patients age 12 years and older were treated with IMBRUVICA 420 mg orally once daily, and patients age 1 year to less than 12 years were treated with IMBRUVICA 240 mg/m 2 orally once daily. Concomitant treatment with supportive care therapies for cGVHD was permitted. Initiation of new systemic cGVHD therapy while on study was not permitted. The median age was 13 years (range, 1 to 19 years). Of the 47 patients, 70% of patients were male, and 36% were White, 9% were Black or African American, 55% were other or unreported. The median time since cGVHD diagnosis was 16.1 months, the median number of prior cGVHD treatments was 2 (range, 1 to 12). The majority of patients (87%) had at least 2 organs involved at baseline, with lung involvement at baseline in 49% of patients; 26% of patients had a Karnofsky/Lansky performance score of <80. The median daily corticosteroid dose (prednisone or prednisone equivalent) at baseline was 0.47 mg/kg/day, and 61% (19 of 31) patients were receiving ongoing immunosuppressants in addition to systemic corticosteroids at baseline. Prophylaxis for infections was managed per institutional guidelines, with 72% of patients receiving combinations of sulfonamides and trimethoprim and 70% receiving systemic antifungal agents. The efficacy of IMBRUVICA was established based on overall response rate (ORR) through Week 25, where overall response included complete response or partial response according to the 2014 National Institutes of Health (NIH) Consensus Development Project Response Criteria. The efficacy results are shown in Table 31 . Table 31: Efficacy Results in Patients with Previously Treated cGVHD a in iMAGINE Total (N=47) ORR by Week 25 28 (60%) 95% CI (%) (44, 74) Complete Response (CR) 2 (4%) Partial Response (PR) 26 (55%) Median d uration of r esponse, months (95% CI) b 5.3 (2.8, 8.8) CI = confidence interval; ORR = overall response rate. a Assessment based on 2014 NIH Consensus Development Project Response Criteria. b Based on all responders in the study, calculated from first response to progression, death, or new systemic therapies for cGVHD. The median time to first response was 0.9 month (range, 0.9 to 6.1 months). The median time from first response to death or new systemic therapies for cGVHD was 14.8 months (95% CI: 4.6, not evaluable). ORR results were supported by exploratory analyses of patient-reported symptom bother which showed at least a 7-point decrease in Lee Symptom Scale overall summary score through Week 25 in 50% (13/26) of patients age 12 years and older.

8.5 Geriatric Use Of 992 patients in clinical studies of IMBRUVICA for B-cell malignancies or cGVHD, 62% were ≥ 65 years of age, while 22% were ≥ 75 years of age [see Clinical Studies ( 14.1 , 14.2 , 14.3 )] . No overall differences in effectiveness were observed between younger and older patients. Anemia (all grades), pneumonia (Grade 3 or higher), thrombocytopenia, hypertension, and atrial fibrillation occurred more frequently among older patients treated with IMBRUVICA [see Adverse Reactions ( 6.1 )] .

8.4 Pediatric Use Chronic GVHD The safety and effectiveness of IMBRUVICA have been established for treatment of cGVHD after failure of one or more lines of systemic therapy in pediatric patients 1 year of age and older. Use of IMBRUVICA for this indication is supported by evidence from iMAGINE, a study which included pediatric patients age 1 year and older with previously treated cGVHD, including patients in the following age groups: one patient 1 year to less than 2 years of age, 20 patients 2 years to less than 12 years of age, and 19 patients 12 years to less than 17 years of age. Additional supportive efficacy data was provided from Study 1129 in adults [see Adverse Reactions ( 6.1 ), Clinical Pharmacology ( 12.3 ), and Clinical Studies ( 14.3 )] . The recommended dosage of IMBRUVICA in patients age 12 years and older is the same as that in adults, and the recommended dosage in patients age 1 year to less than 12 years old is based on body-surface area (BSA) [see Dosage and Administration ( 2.1 )] . The safety and effectiveness of IMBRUVICA have not been established for this indication in pediatric patients less than 1 year of age. Mature B-cell Non-Hodgkin Lymphoma The safety and effectiveness of IMBRUVICA in combination with chemoimmunotherapy were assessed but have not been established based on an open-label, randomized study (NCT02703272) in 35 patients, which included 26 pediatric patients age 5 to less than 17 years, with previously treated mature B-cell non-Hodgkin lymphoma. The study was stopped for futility. In the randomized population, major hemorrhage and discontinuation of chemoimmunotherapy due to adverse reactions occurred more frequently in the ibrutinib plus chemoimmunotherapy arm compared to the chemoimmunotherapy alone arm. CLL/SLL, CLL/SLL with 17p deletion, WM The safety and effectiveness of IMBRUVICA in pediatric patients have not been established in CLL/SLL, CLL/SLL with 17p deletion, or WM.

8.1 Pregnancy Risk Summary IMBRUVICA can cause fetal harm based on findings from animal studies. There are no available data on IMBRUVICA use in pregnant women to inform a drug-associated risk of major birth defects and miscarriage. In animal reproduction studies, administration of ibrutinib to pregnant rats and rabbits during the period of organogenesis at exposures up to 3-20 times the clinical dose of 420 mg daily produced embryofetal toxicity including structural abnormalities (see Data) . Advise pregnant women of the potential risk to a fetus. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively. Data Animal Data Ibrutinib was administered orally to pregnant rats during the period of organogenesis at 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 resorptions and post-implantation loss. The dose of 80 mg/kg/day in rats is approximately 20 times the exposure in patients with CLL/SLL or WM administered a dose of 420 mg daily. Ibrutinib at doses of 40 mg/kg/day or greater was associated with decreased fetal weights. The dose of 40 mg/kg/day in rats is approximately 8 times the exposure (AUC) in patients administered a dose of 420 mg daily. Ibrutinib was also administered orally to pregnant rabbits during the period of organogenesis at doses of 5, 15, and 45 mg/kg/day. Ibrutinib at a dose of 15 mg/kg/day or greater was associated with skeletal variations (fused sternebrae) and ibrutinib at a dose of 45 mg/kg/day was associated with increased resorptions and post-implantation loss. The dose of 15 mg/kg/day in rabbits is approximately 2.8 times the exposure in patients with CLL/SLL or WM administered a dose of 420 mg daily.

8 USE IN SPECIFIC POPULATIONS Lactation : Advise not to breastfeed ( 8.2 ). Hepatic Impairment : Avoid use of IMBRUVICA in patients with severe hepatic impairment. In patients with mild or moderate impairment, reduce IMBRUVICA dose ( 2.4 , 8.6 ). 8.1 Pregnancy Risk Summary IMBRUVICA can cause fetal harm based on findings from animal studies. There are no available data on IMBRUVICA use in pregnant women to inform a drug-associated risk of major birth defects and miscarriage.

Ibrutinib at a dose of 15 mg/kg/day or greater was associated with skeletal variations (fused sternebrae) and ibrutinib at a dose of 45 mg/kg/day was associated with increased resorptions and post-implantation loss. The dose of 15 mg/kg/day in rabbits is approximately 2.8 times the exposure in patients with CLL/SLL or WM administered a dose of 420 mg daily. 8.2 Lactation Risk Summary There is no information regarding the presence of ibrutinib or its metabolites in human milk, the effects on the breastfed child, or the effects on milk production. Because of the potential for serious adverse reactions in the breastfed child, advise women not to breastfeed during treatment with IMBRUVICA and for 1 week after the last dose. 8.3 Females and Males of Reproductive Potential IMBRUVICA can cause fetal harm when administered to pregnant women [see Use in Specific Populations ( 8.1 )] . Pregnancy Testing Verify pregnancy status in females of reproductive potential prior to initiating IMBRUVICA. Contraception Females Advise females of reproductive potential to use effective contraception during treatment with IMBRUVICA and for 1 month after the last dose. Males Advise males with female partners of reproductive potential to use effective contraception during treatment with IMBRUVICA and for 1 month following the last dose. 8.4 Pediatric Use Chronic GVHD The safety and effectiveness of IMBRUVICA have been established for treatment of cGVHD after failure of one or more lines of systemic therapy in pediatric patients 1 year of age and older. Use of IMBRUVICA for this indication is supported by evidence from iMAGINE, a study which included pediatric patients age 1 year and older with previously treated cGVHD, including patients in the following age groups: one patient 1 year to less than 2 years of age, 20 patients 2 years to less than 12 years of age, and 19 patients 12 years to less than 17 years of age. Additional supportive efficacy data was provided from Study 1129 in adults [see Adverse Reactions ( 6.1 ), Clinical Pharmacology ( 12.3 ), and Clinical Studies ( 14.3 )] . The recommended dosage of IMBRUVICA in patients age 12 years and older is the same as that in adults, and the recommended dosage in patients age 1 year to less than 12 years old is based on body-surface area (BSA) [see Dosage and Administration ( 2.1 )] . The safety and effectiveness of IMBRUVICA have not been established for this indication in pediatric patients less than 1 year of age. Mature B-cell Non-Hodgkin Lymphoma The safety and effectiveness of IMBRUVICA in combination with chemoimmunotherapy were assessed but have not been established based on an open-label, randomized study (NCT02703272) in 35 patients, which included 26 pediatric patients age 5 to less than 17 years, with previously treated mature B-cell non-Hodgkin lymphoma. The study was stopped for futility. In the randomized population, major hemorrhage and discontinuation of chemoimmunotherapy due to adverse reactions occurred more frequently in the ibrutinib plus chemoimmunotherapy arm compared to the chemoimmunotherapy alone arm. CLL/SLL, CLL/SLL with 17p deletion, WM The safety and effectiveness of IMBRUVICA in pediatric patients have not been established in CLL/SLL, CLL/SLL with 17p deletion, or WM. 8.5 Geriatric Use Of 992 patients in clinical studies of IMBRUVICA for B-cell malignancies or cGVHD, 62% were ≥ 65 years of age, while 22% were ≥ 75 years of age [see Clinical Studies ( 14.1 , 14.2 , 14.3 )] . No overall differences in effectiveness were observed between younger and older patients. Anemia (all grades), pneumonia (Grade 3 or higher), thrombocytopenia, hypertension, and atrial fibrillation occurred more frequently among older patients treated with IMBRUVICA [see Adverse Reactions ( 6.1 )] . 8.6 Hepatic Impairment Adult Patients with B-cell Malignancies Avoid use of IMBRUVICA in patients with severe hepatic impairment (Child-Pugh class C). The safety of IMBRUVICA has not been evaluated in patients with mild to severe hepatic impairment by Child-Pugh criteria.
