For CLL/SLL, IMBRUVICA can be administered as a single agent, in combination with rituximab or obinutuzumab, or in combination with bendamustine and rituximab (BR). For WM, IMBRUVICA can be administered as a single agent or in combination with rituximab. When administering IMBRUVICA in combination with rituximab or obinutuzumab, consider administering IMBRUVICA prior to rituximab or obinutuzumab when given on the same day. Chronic Graft versus Host Disease The recommended dosage of IMBRUVICA for patients age 12 years and older with cGVHD is 420 mg orally once daily, and for patients 1 to less than 12 years of age with cGVHD is…
The following clinically significant adverse reactions are described elsewhere in the labeling: Hemorrhage [see Warnings and Precautions ( 5.1 )] Infections [see Warnings and Precautions ( 5.2 )] Cardiac Arrhythmias, Cardiac Failure, and Sudden Death [see Warnings and Precautions ( 5.3 )] Hypertension [see Warnings and Precautions ( 5.4 )] Cytopenias [see Warnings and Precautions ( 5.5 )] Second Primary Malignancies [see Warnings and Precautions ( 5.6 )] Hepatotoxicity, including DILI [see Warning s and Precautions ( 5.7 )] Tumor Lysis Syndrome [see Warnings and Precautions ( 5.8 )] The most common (≥30%) adverse reactions in patients with B-cell malignancies are thrombocytopenia, diarrhea, fatigue, musculoskeletal pain, neutropenia, rash, anemia, bruising, and nausea ( 6 ). The most common (≥20%) adverse reactions in adult or pediatric patients with cGVHD are fatigue, anemia, bruising, diarrhea, thrombocytopenia, musculoskeletal pain, pyrexia, muscle spasms, stomatitis, hemorrhage, nausea, abdominal pain, pneumonia, and headache ( 6 ). To report SUSPECTED ADVERSE REACTIONS, contact AbbVie at 1-800-633-9110 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience Because clinical trials are conducted under widely variable conditions, adverse reaction rates observed in clinical trials of a drug cannot be directly compared with rates of clinical trials of…
Important safety information
Hemorrhage : Monitor for bleeding and manage ( 5.1 ). Infections : Monitor patients for fever and infections, evaluate promptly, and treat ( 5.2 ). Cardiac Arrhythmias , Cardiac Failure , and Sudden Death : Monitor for symptoms of arrhythmias and cardiac failure and manage ( 5.3 ). Hypertension : Monitor blood pressure and treat ( 5.4 ). Cytopenias : Check complete blood counts monthly ( 5.5 ). Second Primary Malignancies : Other malignancies have occurred in patients, including skin cancers, and other carcinomas ( 5.6 ). Hepatotoxicity, Including Drug- Induced Liver Injury : Monitor hepatic function throughout treatment ( 5.7 ). Tumor Lysis Syndrome (TLS) : Assess baseline risk and take precautions. Monitor and treat for TLS ( 5.8 ). Embryo-Fetal Toxicity : Can cause fetal harm. Advise females of reproductive potential of the potential risk to a fetus and to use effective contraception ( 5.9 , 8.1 , 8.3 ). 5.1 Hemorrhage Fatal bleeding events have occurred in patients who received IMBRUVICA. Major hemorrhage (≥ Grade 3, serious, or any central nervous system events; e.g., intracranial hemorrhage [including subdural hematoma], gastrointestinal bleeding, hematuria, and post procedural hemorrhage) occurred in 4.2% of patients, with fatalities occurring in 0.4% of 2,838 patients who received IMBRUVICA in 27 clinical trials. Bleeding events of any grade including bruising and…
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 ) ] .
