The effectiveness of ARZERRA is based on the demonstration of durable objective responses. No data demonstrate an improvement in disease-related symptoms or increased survival with ARZERRA.Important Safety InformationHighlights of Warnings and PrecautionsInfusion Reactions: Premedicate with an intravenous corticosteroid(as appropriate), an oral analgesic, and an oral or intravenous antihistamine. Monitor patients closely during infusions. Interrupt infusion if infusion reactions occur.Cytopenias: Monitor blood counts at regular intervals for neutropenia and thrombocytopenia.Progressive Multifocal Leukoencephalopathy (PML): Monitor neurologic function and discontinue ARZERRA if PML is suspected.Hepatitis B Infection and Reactivation: Screen high-risk patients.Discontinue ARZERRA in patients who develop viral hepatitis or reactivation of viral hepatitis.Infusion ReactionsARZERRA can cause serious infusion reactions manifesting as bronchospasm, dyspnea, laryngeal edema, pulmonary edema, flushing, hypertension, hypotension, syncope, cardiac ischemia/infarction, back pain, abdominal pain, pyrexia, rash, urticaria, and angioedema.Infusion reactions occur more frequently with the first 2 infusions.Premedicate with acetaminophen, an antihistamine, and a corticosteroid. Interrupt infusion for infusion reactions of any severity. Institute medical management for severe infusion reactions including angina, or other signs and symptoms of myocardial ischemia. In a study of patients with moderate to severe chronic obstructive pulmonary disease, an indication for which ARZERRA is not approved, 2 of 5 patients developed Grade 3 bronchospasm during infusion. Infusion reactions occurred in 44% of patients on the day of the first infusion (300 mg), 29% on the day of the second infusion (2,000 mg), and less frequently during subsequentinfusions.CytopeniasProlonged (>1 week) severe neutropenia and thrombocytopenia can occur with ARZERRA. Monitor complete blood counts (CBC) and platelet counts at regular intervals during therapy, and increase the frequency of monitoring in patients who develop Grade 3 or 4 cytopenias. Of 108 patients with normal neutrophil counts at baseline, 45 (42%) developed >Grade 3 neutropenia. Nineteen (18%) developed Grade 4 neutropenia. Some patients experienced new onset Grade 4 neutropenia >2 weeks in duration.Progressive Multifocal LeukoencephalopathyProgressive multifocal leukoencephalopathy (PML), including fatal PML, can occur with ARZERRA.Consider PML in any patient with new onset of or changes in pre-existing neurological signs or symptoms.Discontinue ARZERRA if PML is suspected and initiate eva luation for PML including consultation with a neurologist, brain MRI, and lumbar puncture.Hepatitis B Infection and ReactivationFulminant and fatal hepatitis B virus (HBV) infection and reactivation can occur in patients following treatment with ARZERRA.Screen patients at high risk of HBV infection before initiation of ARZERRA.Closely monitor carriers of hepatitis B for clinical and laboratory signs of active HBV infection during treatment with ARZERRA and for 6 to 12 months following the last infusion of ARZERRA.Discontinue ARZERRA in patients who develop viral hepatitis or reactivation of viral hepatitis, and institute appropriate treatment.Insufficient data exist regarding the safety of administration of ARZERRA in patients with active hepatitis.Intestinal ObstructionObstruction of the small intestine can occur in patients receiving ARZERRA. Perform a diagnostic eva luation if obstruction issuspected.ImmunizationsThe safety of immunization with live viral vaccines during or following administration of ARZERRA has not been studied.Do not administer live viral vaccines to patients who have recently received ARZERRA. The ability to generate an immune response to any vaccine following administration of ARZERRA has not been studied.Most Common Adverse ReactionsIn the pivotal study (total population, n=154) the most common adverse reactions (>10%, all grades) were neutropenia, followed by pneumonia (23%), pyrexia (20%), cough (19%), diarrhea (18%), anemia (16%), fatigue (15%), dyspnea (14%), rash (14%), nausea (11%), bronchitis (11%), and upper respiratory tract infections (11%).Most Common Serious Adverse ReactionsIn the pivotal study (total population, n=154), where ARZERRA was administered at 2,000 mg beginning with the second dose for 11 doses, the most common serious adverse reactions were infections(including pneumonia and sepsis), neutropenia, and pyrexia.A total of 108 patients (70%) experienced bacterial, viral, or fungal infections. A total of 45 patients (29%) experienced >Grade 3 infections, of which 19 (12%) were fatal.The proportion of fatal infections in the fludarabine- and alemtuzumab-refractory group was 17%.
