( 1.1 ) Relapsed or refractory CD19-positive B-cell precursor acute lymphoblastic leukemia (ALL). ( 1.2 ) CD19-positive Philadelphia chromosome-negative B-cell precursor acute lymphoblastic leukemia (ALL) in the consolidation phase of multiphase chemotherapy.

Side Effects
6 ADVERSE REACTIONS The following clinically significant adverse reactions are described elsewhere in the labeling: Cytokine Release Syndrome [see Warnings and Precautions (5.1) ] Neurological Toxicities, including Immune Effector Cell-Associated Neurotoxicity Syndrome [see Warnings and Precautions (5.2) ] Infections [see Warnings and Precautions (5.3) ] Tumor Lysis Syndrome [see Warnings and Precautions (5.4) ] Neutropenia and Febrile Neutropenia [see Warnings and Precautions (5.5) ] Effects on Ability to Drive and Use Machines [see Warnings and Precautions (5.6) ] Elevated Liver Enzymes [see Warnings and Precautions (5.7) ] Pancreatitis [see Warnings and Precautions (5.8) ] Leukoencephalopathy [see Warnings and Precautions (5.9) ] The most common adverse reactions (≥ 20%) are pyrexia, in...
Interactions
7 DRUG INTERACTIONS No formal drug interaction studies have been conducted with BLINCYTO. Initiation of BLINCYTO treatment causes transient release of cytokines that may suppress CYP450 enzymes. The highest drug-drug interaction risk is during the first 9 days of the first cycle and the first 2 days of the second cycle in patients who are receiving concomitant CYP450 substrates, particularly those with a narrow therapeutic index. In these patients, monitor for toxicity (e.g., warfarin) or drug concentrations (e.g., cyclosporine). Adjust the dose of the concomitant drug as needed [see Clinical Pharmacology (12.2 , 12.3) ] .
Warnings
WARNING: CYTOKINE RELEASE SYNDROME and NEUROLOGICAL TOXICITIES including IMMUNE EFFECTOR CELL-ASSOCIATED NEUROTOXICITY SYNDROME Cytokine Release Syndrome (CRS), which may be life-threatening or fatal, occurred in patients receiving BLINCYTO. Interrupt or discontinue BLINCYTO and treat with corticosteroids as recommended [see Dosage and Administration (2.4) , Warnings and Precautions (5.1) ] . 5 WARNINGS AND PRECAUTIONS Infections: Monitor patients for signs or symptoms; treat appropriately. ( 5.3 ) Effects on Ability to Drive and Use Machines: Advise patients to refrain from driving and engaging in hazardous occupations or activities such as operating heavy or potentially dangerous machinery while BLINCYTO is being administered. ( 5.6 ) Pancreatitis: Evaluate patients who develop signs and symptoms of pancreatitis. Management of pancreatitis may require either temporary interruption or discontinuation of BLINCYTO. ( 5.8 ) Preparation and Administration Errors: Strictly follow instructions for preparation (including admixing) and administration. ( 5.10 ) Benzyl Alcohol Toxicity in Neonates: Use BLINCYTO prepared with preservative-free saline for neonates. 4 CONTRAINDICATIONS BLINCYTO is contraindicated in patients with known hypersensitivity to blinatumomab or to any component of the product formulation. Known hypersensitivity to blinatumomab or to any component of the product formulation. ( 4 )
Pregnancy
8.1 Pregnancy Risk Summary Based on its mechanism of action, BLINCYTO may cause fetal harm when administered to a pregnant woman [see Clinical Pharmacology (12.1) ] . There are no available data on the use of BLINCYTO in pregnant women to evaluate for a drug-associated risk. In animal reproduction studies, a murine surrogate molecule administered to pregnant mice crossed the placental barrier (see Data ) . Blinatumomab causes T-cell activation and cytokine release; immune activation may compromise pregnancy maintenance.
Storage
Store BLINCYTO and IV Solution Stabilizer vials in the original package refrigerated at 2°C to 8°C (36°F to 46°F) and protect from light until time of use. Do not freeze. BLINCYTO and IV Solution Stabilizer vials may be stored for a maximum of 8 hours at room temperature [23°C to 27°C (73°F to 81°F)] in the original carton to protect from light.
