    2.4       Preparation

    It is very important that the instructions for preparation (including admixing) and administration provided in this section are strictly followed to minimize medication errors (including underdose and overdose) [see Warnings and Precautions (5.10)]. 

    BLINCYTO can be infused over 24 hours (preservative-free), 48 hours (preservative-free), or 7 days (with preservative). The choice between these options for the infusion duration should be made by the treating healthcare provider considering the frequency of the infusion bag changes and the weight of the patient.  The administration of BLINCYTO as a 7-day infusion is not recommended for patients weighing less than 22 kg.

    For preparation, reconstitution, and administration of BLINCYTO:

    • See Section 2.5 for infusion over 24 hours or 48 hours.
    • See Section 2.6 for infusion over 7 days using Bacteriostatic 0.9% Sodium Chloride Injection, USP (containing 0.9% benzyl alcohol). This option is available for patients weighing 22 kg or more. It is not recommended for patients weighing less than 22 kg.

    Call 1-800-77-AMGEN (1-800-772-6436) if you have questions about the reconstitution and preparation of BLINCYTO.

    2.4.1    Aseptic Preparation

    Strictly observe aseptic technique when preparing the solution for infusion since BLINCYTO vials do not contain antimicrobial preservatives. To prevent accidental contamination, prepare BLINCYTO according to aseptic standards, including but not limited to:

    • Prepare BLINCYTO in a USP <797> compliant facility.
    • Prepare BLINCYTO in an ISO Class 5 laminar flow hood or better.
    • Ensure that the admixing area has appropriate environmental specifications, confirmed by periodic monitoring.
    • Ensure that personnel are appropriately trained in aseptic manipulations and admixing of oncology drugs.
    • Ensure that personnel wear appropriate protective clothing and gloves.
      Ensure that gloves and surfaces are disinfected.

    2.4.2    Package Content

    1 package BLINCYTO includes 1 vial of BLINCYTO and 1 vial of IV Solution Stabilizer.

    • Do not use IV Solution Stabilizer for reconstitution of BLINCYTO.  IV Solution Stabilizer is provided with the BLINCYTO package and is used to coat the intravenous bag prior to addition of reconstituted BLINCYTO to prevent adhesion of BLINCYTO to intravenous bags and intravenous tubing.
    • More than 1 package of BLINCYTO may be needed to prepare the recommended dose.     

    2.4.3    Incompatibility Information

    BLINCYTO is incompatible with di-ethylhexylphthalate (DEHP) due to the possibility of particle formation, leading to a cloudy solution.

    • Use polyolefin, PVC DEHP-free, or ethyl vinyl acetate (EVA) infusion bags/pump cassettes.
    • Use polyolefin, PVC DEHP-free, or EVA intravenous tubing sets.

    2.5       Preparation and Administration of BLINCYTO as 24-Hour or 48-Hour Infusion

    Reconstitute BLINCYTO with preservative-free Sterile Water for Injection, USP. Do not reconstitute BLINCYTO vials with the IV Solution Stabilizer.

    To prime the intravenous tubing, use only the solution in the bag containing the FINAL prepared BLINCYTO solution for infusion. Do not prime with 0.9% Sodium Chloride Injection, USP.

    2.5.1    Reconstitution of BLINCYTO for 24-Hour or 48-Hour Infusion 

      1.    Determine the number of BLINCYTO vials needed for a dose and infusion duration.

      2.    Reconstitute each BLINCYTO vial with 3 mL of preservative-free Sterile Water for Injection, USP by directing the water along the walls of the BLINCYTO vial and not directly on the lyophilized powder. The resulting concentration per BLINCYTO vial is 12.5 mcg/mL.

             ● Do not reconstitute BLINCYTO vials with IV Solution Stabilizer.  

      3.    Gently swirl contents to avoid excess foaming.  

             ● Do not shake.

      4.    Visually inspect the reconstituted solution for particulate matter and discoloration during reconstitution and prior to infusion. The resulting solution should be clear to slightly opalescent, colorless to slightly yellow.

             ● Do not use if solution is cloudy or has precipitated.

    2.5.2    Preparation of BLINCYTO Infusion Bag for 24-Hour or 48-Hour Infusion

    Verify the prescribed dose and infusion duration for each BLINCYTO infusion bag. To minimize errors, use the specific volumes described in Tables 4 and 5 to prepare the BLINCYTO infusion bag. 

      ●    Table 4 for patients weighing 45 kg or more

      ●    Table 5 for patients weighing less than 45 kg

      1.    Aseptically add 270 mL 0.9% Sodium Chloride Injection, USP to the empty intravenous bag.

      2.    Aseptically transfer 5.5 mL IV Solution Stabilizer to the intravenous bag containing 0.9% Sodium Chloride Injection, USP. Gently mix the contents of the bag to avoid foaming. Discard the vial containing the unused IV Solution Stabilizer.

      3.    Aseptically transfer the required volume of reconstituted BLINCYTO solution into the intravenous bag containing 0.9% Sodium Chloride Injection, USP and IV Solution Stabilizer. Gently mix the contents of the bag to avoid foaming.

             ● Refer to Table 4 for patients weighing 45 kg or more for the specific volume of reconstituted BLINCYTO.

             ● Refer to Table 5 for patients weighing less than 45 kg (dose based on BSA) for the specific volume of reconstituted BLINCYTO.

             ● Discard the vial containing unused BLINCYTO.

      4.    Under aseptic conditions, attach the intravenous tubing to the intravenous bag with the sterile 0.2 micron in-line filter. Ensure that the intravenous tubing is compatible with the infusion pump.

      5.    Remove air from the intravenous bag. This is particularly important for use with an ambulatory infusion pump.

      6.    Prime the intravenous tubing only with the solution in the bag containing the FINAL prepared BLINCYTO solution for infusion.

    2.5.3 Administration of BLINCYTO for 24-Hour or 48-Hour Infusion

      ● Administer BLINCYTO as a continuous intravenous infusion at a constant flow rate using an infusion pump. The pump should be programmable, lockable, non-elastomeric, and have an alarm.

      ● The starting volume (270 mL) is more than the volume administered to the patient (240 mL) to account for the priming of the intravenous tubing and to ensure that the patient will receive the full dose of BLINCYTO.

      ● Infuse prepared BLINCYTO final infusion solution according to the instructions on the pharmacy label on the prepared bag at one of the following constant infusion rates:
             - Infusion rate of 10 mL/hour for a duration of 24 hours, OR
             - Infusion rate of 5 mL/hour for a duration of 48 hours

      ● Administer prepared BLINCYTO final infusion solution using intravenous tubing that contains a sterile, non-pyrogenic, low protein-binding, 0.2 micron in-line filter. For 7-day bag administration information, see section 2.6.3.

      ● Important Note: Do not flush the BLINCYTO infusion line or intravenous catheter, especially when changing infusion bags. Flushing when changing bags or at completion of infusion can result in excess dosage and complications thereof. When administering via a multi-lumen venous catheter, infuse BLINCYTO through a dedicated lumen. 

      ● At the end of the infusion, discard any unused BLINCYTO solution in the intravenous bag and intravenous tubing in accordance with local requirements.

    2.6.3       Administration of BLINCYTO as a 7-Day Infusion

    ● Administer BLINCYTO as a continuous intravenous infusion at a constant flow rate using an infusion pump. The pump should be programmable, lockable, non-elastomeric, and have an alarm.

    ● The final volume of infusion solution (110 mL) will be more than the volume administered to the patient (100 mL) to account for the priming of the intravenous tubing and to ensure that the patient will receive the full dose of BLINCYTO.

    ● Do not use an in-line filter for a 7-day bag.

    ● Infuse prepared BLINCYTO final infusion solution according to the instructions on the pharmacy label on the prepared bag at an infusion rate of 0.6 mL/hour for a duration of 7 days.

    ● Important Note: Do not flush the BLINCYTO infusion line or intravenous catheter, especially when changing infusion bags. Flushing when changing bags or at completion of infusion can result in excess dosage and complications thereof. When administering via a multi-lumen venous catheter, infuse BLINCYTO through a dedicated lumen.

    ● At the end of the infusion, dispose of any unused BLINCYTO solution in the intravenous bag and intravenous tubing in accordance with local requirements.

    2.7       Storage of Reconstituted BLINCYTO

  • 3       DOSAGE FORMS AND STRENGTHS

    For injection: 35 mcg of white to off-white lyophilized powder in a single-dose vial for reconstitution.

  • 4       CONTRAINDICATIONS

    BLINCYTO is contraindicated in patients with known hypersensitivity to blinatumomab or to any component of the product formulation.

  • 5       WARNINGS AND PRECAUTIONS

    5.1       Cytokine Release Syndrome

    Cytokine Release Syndrome (CRS), which may be life-threatening or fatal, occurred in patients receiving BLINCYTO. The median time to onset of CRS was 2 days after the start of infusion and the median time to resolution of CRS was 5 days among cases that resolved. Manifestations of CRS include fever, headache, nausea, asthenia, hypotension, increased alanine aminotransferase (ALT), increased aspartate aminotransferase (AST), increased total bilirubin, and disseminated intravascular coagulation (DIC). The manifestations of CRS after treatment with BLINCYTO overlap with those of infusion reactions, capillary leak syndrome (CLS), and hemophagocytic histiocytosis/macrophage activation syndrome (MAS). Using all of these terms to define CRS in clinical trials of BLINCYTO, CRS was reported in 15% of patients with relapsed or refractory ALL and in 7% of patients with MRD-positive ALL.

    Monitor patients for signs or symptoms of these events. Advise outpatients on BLINCYTO to contact their healthcare professional for signs and symptoms associated with CRS. If severe CRS occurs, interrupt BLINCYTO until CRS resolves. Discontinue BLINCYTO permanently if life-threatening CRS occurs. Administer corticosteroids for severe or life-threatening CRS [see Dosage and Administration (2.3)].

    5.2       Neurological Toxicities

    In patients with ALL receiving BLINCYTO in clinical studies, neurological toxicities have occurred in approximately 65% of patients. Among patients that experienced a neurologic event, the median time to the first event was within the first 2 weeks of BLINCYTO treatment and the majority of events resolved. The most common (≥ 10%) manifestations of neurological toxicity were headache, and tremor; the neurological toxicity profile varied by age group [see Use in Specific Populations (8.4, 8.5)]. Grade 3 or higher (severe, life-threatening, or fatal) neurological toxicities following initiation of BLINCYTO administration occurred in approximately 13% of patients and included encephalopathy, convulsions, speech disorders, disturbances in consciousness, confusion and disorientation, and coordination and balance disorders.  Manifestations of neurological toxicity included cranial nerve disorders. The majority of neurologic events resolved following interruption of BLINCYTO, but some resulted in treatment discontinuation.

    There is limited experience with BLINCYTO in patients with active ALL in the central nervous system (CNS) or a history of neurologic events. Patients with a history or presence of clinically relevant CNS pathology were excluded from clinical studies.

    Monitor patients receiving BLINCYTO for signs and symptoms of neurological toxicities. Advise outpatients on BLINCYTO to contact their healthcare professional if they develop signs or symptoms of neurological toxicities. Interrupt or discontinue BLINCYTO as recommended [see Dosage and Administration (2.3)].   

    5.3       Infections

    In patients with ALL receiving BLINCYTO in clinical studies, serious infections such as sepsis, pneumonia, bacteremia, opportunistic infections, and catheter-site infections were observed in approximately 25% of patients, some of which were life-threatening or fatal. As appropriate, administer prophylactic antibiotics and employ surveillance testing during treatment with BLINCYTO. Monitor patients for signs and symptoms of infection and treat appropriately.

    5.4       Tumor Lysis Syndrome

    Tumor lysis syndrome (TLS), which may be life-threatening or fatal, has been observed in patients receiving BLINCYTO. Appropriate prophylactic measures, including pretreatment nontoxic cytoreduction and on-treatment hydration, should be used for the prevention of TLS during BLINCYTO treatment. Monitor for signs or symptoms of TLS. Management of these events may require either temporary interruption or discontinuation of BLINCYTO [see Dosage and Administration (2.3)].

    5.5       Neutropenia and Febrile Neutropenia

    Neutropenia and febrile neutropenia, including life-threatening cases, have been observed in patients receiving BLINCYTO. Monitor laboratory parameters (including, but not limited to, white blood cell count and absolute neutrophil count) during BLINCYTO infusion. Interrupt BLINCYTO if prolonged neutropenia occurs.

    5.6       Effects on Ability to Drive and Use Machines

    Due to the potential for neurologic events, including seizures, patients receiving BLINCYTO are at risk for loss of consciousness [see Warnings and Precautions (5.2)]. 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.

    5.7       Elevated Liver Enzymes

    Treatment with BLINCYTO was associated with transient elevations in liver enzymes.  In patients with ALL receiving BLINCYTO in clinical studies, the median time to onset of elevated liver enzymes was 3 days.

    The majority of these transient elevations in liver enzymes were observed in the setting of CRS. For the events that were observed outside the setting of CRS, the median time to onset was 19 days. Grade 3 or greater elevations in liver enzymes occurred in approximately 7% of patients outside the setting of CRS and resulted in treatment discontinuation in less than 1% of patients.

    Monitor alanine aminotransferase (ALT), aspartate aminotransferase (AST), gamma-glutamyl transferase (GGT), and total blood bilirubin prior to the start of and during BLINCYTO treatment. Interrupt BLINCYTO if the transaminases rise to greater than 5 times the upper limit of normal or if total bilirubin rises to more than 3 times the upper limit of normal.

    5.8       Pancreatitis

    Fatal pancreatitis has been reported in patients receiving BLINCYTO in combination with dexamethasone in clinical studies and the postmarketing setting [see Adverse Reactions (6.3)].

    Evaluate patients who develop signs and symptoms of pancreatitis. Management of pancreatitis may require either temporary interruption or discontinuation of BLINCYTO and dexamethasone [see Dosage and Administration (2.3)].

    5.9       Leukoencephalopathy

    Cranial magnetic resonance imaging (MRI) changes showing leukoencephalopathy have been observed in patients receiving BLINCYTO, especially in patients with prior treatment with cranial irradiation and antileukemic chemotherapy (including systemic high-dose methotrexate or intrathecal cytarabine). The clinical significance of these imaging changes is unknown.   

    5.10       Preparation and Administration Errors

    Preparation and administration errors have occurred with BLINCYTO treatment. Follow instructions for preparation (including admixing) and administration strictly to minimize medication errors (including underdose and overdose) [see Dosage and Administration (2.4)].

    5.11       Immunization

    The safety of immunization with live viral vaccines during or following BLINCYTO therapy has not been studied. Vaccination with live virus vaccines is not recommended for at least 2 weeks prior to the start of BLINCYTO treatment, during treatment, and until immune recovery following last cycle of BLINCYTO.

    5.12       Risk of Serious Adverse Reactions in Pediatric Patients due to Benzyl Alcohol Preservative

    Serious and fatal adverse reactions including “gasping syndrome” can occur in neonates and infants treated with benzyl alcohol-preserved drugs, including BLINCYTO (with preservative). The “gasping syndrome” is characterized by central nervous system depression, metabolic acidosis, and gasping respirations.

    When prescribing BLINCYTO (with preservative) for pediatric patients, consider the combined daily metabolic load of benzyl alcohol from all sources including BLINCYTO (with preservative) (contains 7.4 mg of benzyl alcohol per mL) and other drugs containing benzyl alcohol. The minimum amount of benzyl alcohol at which serious adverse reactions may occur is not known [see Use in Specific Populations (8.4)].

    Due to the addition of bacteriostatic saline, 7-day infusion bags of BLINCYTO solution contain benzyl alcohol and are not recommended for use in any patients weighing less than 22 kg [see Dosage and Administration (2.6) and Use in Specific Populations (8.4)].

  • 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 [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)]

    • Pancreatitis [see Warnings and Precautions (5.8)]
    • Leukoencephalopathy [see Warnings and Precautions (5.9)]

    6.1       Clinical Trials Experience

    Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

    MRD-positive B-cell Precursor ALL

    The safety of BLINCYTO in patients with MRD-positive B-cell precursor ALL was evaluated in two single-arm clinical studies in which 137 patients were treated with BLINCYTO. The median age of the study population was 45 years (range: 18 to 77 years).

    The most common adverse reactions (≥ 20%) were pyrexia, infusion related reactions, headache, infections (pathogen unspecified), tremor, and chills. Serious adverse reactions were reported in 61% of patients. The most common serious adverse reactions (≥ 2%) included pyrexia, tremor, encephalopathy, aphasia, lymphopenia, neutropenia, overdose, device related infection, seizure, and staphylococcal infection. Adverse reactions of Grade 3 or higher were reported in 64% of patients. Discontinuation of therapy due to adverse reactions occurred in 17% of patients; neurologic events were the most frequently reported reasons for discontinuation. There were 2 fatal adverse reactions that occurred within 30 days of the end of BLINCYTO treatment (atypical pneumonia and subdural hemorrhage).

    Table 8 summarizes the adverse reactions occurring at a ≥ 10% incidence for any grade or ≥ 5% incidence for Grade 3 or higher.

    Philadelphia Chromosome-negative Relapsed or Refractory B-cell Precursor ALL

    The safety of BLINCYTO was evaluated in a randomized, open-label, active-controlled clinical study (TOWER Study) in which 376 patients with Philadelphia chromosome-negative relapsed or refractory B-cell precursor ALL were treated with BLINCYTO (n = 267) or standard of care (SOC) chemotherapy (n = 109). The median age of BLINCYTO-treated patients was 37 years (range: 18 to 80 years), 60% were male, 84% were White, 7% Asian, 2% were Black or African American, 2% were American Indian or Alaska Native, and 5% were Multiple/Other.

    The most common adverse reactions (≥ 20%) in the BLINCYTO arm were infections (bacterial and pathogen unspecified), pyrexia, headache, infusion-related reactions, anemia, febrile neutropenia, thrombocytopenia, and neutropenia. Serious adverse reactions were reported in 62% of patients. The most common serious adverse reactions (≥ 2%) included febrile neutropenia, pyrexia, sepsis, pneumonia, overdose, septic shock, CRS, bacterial sepsis, device related infection, and bacteremia. Adverse reactions of Grade 3 or higher were reported in 87% of patients. Discontinuation of therapy due to adverse reactions occurred in 12% of patients treated with BLINCYTO; neurologic events and infections were the most frequently reported reasons for discontinuation of treatment due to an adverse reaction. Fatal adverse events occurred in 16% of patients. The majority of the fatal events were infections.

    The adverse reactions occurring at a ≥ 10% incidence for any grade or ≥ 5% incidence for Grade 3 or higher in the BLINCYTO-treated patients in first cycle of therapy are summarized in Table 10.

    Vascular disorders: hypotension (includes blood pressure decreased, hypotension, hypovolemic shock, and circulatory collapse), hypertension (includes blood pressure increased, hypertension, and hypertensive crisis), flushing (includes flushing and hot flush), and capillary leak syndrome

    6.2       Immunogenicity

    As with all therapeutic proteins, there is potential for immunogenicity. The detection of antibody formation is highly dependent on the sensitivity and specificity of the assay. Additionally, the observed incidence of antibody (including neutralizing antibody) positivity in an assay may be influenced by several factors, including assay methodology, sample handling, timing of sample collection, concomitant medications, and underlying disease. For these reasons, comparison of the incidence of antibodies to blinatumomab with the incidence of antibodies to other products may be misleading.

    The immunogenicity of BLINCYTO has been evaluated using either an electrochemiluminescence detection technology (ECL) or an enzyme-linked immunosorbent assay (ELISA) screening immunoassay for the detection of binding anti-blinatumomab antibodies. For patients whose sera tested positive in the screening immunoassay, an in vitro biological assay was performed to detect neutralizing antibodies.

    In clinical studies, less than 2% of patients treated with BLINCYTO tested positive for binding anti-blinatumomab antibodies. Of patients who developed anti-blinatumomab antibodies, 7 out of 9 (78%) had in vitro neutralizing activity. Anti-blinatumomab antibody formation may affect pharmacokinetics of BLINCYTO.

    If formation of anti-blinatumomab antibodies with a clinically significant effect is suspected, contact Amgen at 1-800-77-AMGEN (1-800-772-6436) to discuss antibody testing.

    6.3       Postmarketing Experience

    The following adverse reactions have been identified during postapproval use of BLINCYTO. 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.

          Fatal pancreatitis has been reported in patients receiving BLINCYTO in combination with dexamethasone.

  • 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)].

  • 8       USE IN SPECIFIC POPULATIONS

    8.1       Pregnancy

    Risk Summary

    Based on its mechanism of action, BLINCYTO may cause fetal harm, including B-cell lymphocytopenia, when administered to a pregnant woman [see Clinical Pharmacology (12.1)]. There are no data on the use of BLINCYTO in pregnant women. In animal reproduction studies, a murine surrogate molecule administered to pregnant mice crossed the placental barrier (see Data). Advise pregnant women of the potential risk to a fetus.

    The background rate of major birth defects and miscarriage is unknown for the indicated population.  All pregnancies have a background risk of birth defect, loss, or other adverse outcomes.  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.

    Clinical Considerations

    Fetal/Neonatal Adverse Reactions

    Due to the potential for B-cell lymphocytopenia in infants following exposure to BLINCYTO in utero, the infant’s B lymphocytes should be monitored before the initiation of live virus vaccination [see Warnings and Precautions (5.11)].

    Data

    Animal Data

    Animal reproduction studies have not been conducted with blinatumomab. In embryo-fetal developmental toxicity studies, a murine surrogate molecule was administered intravenously to pregnant mice during the period of organogenesis. The surrogate molecule crossed the placental barrier and did not cause embryo-fetal toxicity or teratogenicity. The expected depletions of B and T cells were observed in the pregnant mice, but hematological effects were not assessed in fetuses.

    8.2       Lactation

    Risk Summary

    There is no information regarding the presence of blinatumomab in human milk, the effects on the breastfed infant, or the effects on milk production. Because many drugs are excreted in human milk and because of the potential for serious adverse reactions in breastfed infants from BLINCYTO, including B-cell lymphocytopenia, advise patients not to breastfeed during treatment with BLINCYTO and for at least 48 hours after the last dose.

    8.3       Females and Males of Reproductive Potential

    Pregnancy Testing

    Verify the pregnancy status of females of reproductive potential prior to initiating BLINCYTO treatment.

    Contraception

    Females
    BLINCYTO may cause fetal harm when administered to a pregnant woman [see Use in Specific Populations (8.1)]. Advise females of reproductive potential to use effective contraception during treatment with BLINCYTO and for at least 48 hours after the last dose.

    8.4       Pediatric Use

    The safety and efficacy of BLINCYTO have been established in pediatric patients with relapsed or refractory B-cell precursor ALL. Use of BLINCYTO is supported by a single-arm trial in pediatric patients with relapsed or refractory B-cell precursor ALL. This study included pediatric patients in the following age groups: 10 infants (1 month up to less than 2 years), 40 children (2 years up to less than 12 years), and 20 adolescents (12 years to less than 18 years). No differences in efficacy were observed between the different age subgroups. The efficacy has also been established based on extrapolation from adequate and well-controlled studies in adults with MRD-positive B-cell precursor ALL.

    In general, the adverse reactions in BLINCYTO-treated pediatric patients were similar in type to those seen in adult patients with relapsed or refractory B-cell precursor ALL [see Adverse Reactions (6.1)]. Adverse reactions that were observed more frequently (≥ 10% difference) in the pediatric population compared to the adult population were pyrexia (80% vs. 61%), hypertension (26% vs. 8%), anemia (41% vs. 24%), infusion-related reaction (49% vs. 34%), thrombocytopenia (34% vs. 21%), leukopenia (24% vs. 11%), and weight increased (17% vs. 6%).

    In pediatric patients less than 2 years old (infants), the incidence of neurologic toxicities was not significantly different than for the other age groups, but its manifestations were different; the only event terms reported were agitation, headache, insomnia, somnolence, and irritability. Infants also had an increased incidence of hypokalemia (50%) compared to other pediatric age cohorts (15-20%) or adults (17%).

    The steady-state concentrations of blinatumomab were comparable in adult and pediatric patients at the equivalent dose levels based on BSA-based regimens.

    Benzyl Alcohol Toxicity in Pediatric Patients 

    Serious adverse reactions including fatal reactions and the “gasping syndrome” occurred in premature neonates and infants in the neonatal intensive care unit who received drugs containing benzyl alcohol as a preservative. In these cases, benzyl alcohol dosages of 99 to 234 mg/kg/day produced high levels of benzyl alcohol and its metabolites in the blood and urine (blood levels of benzyl alcohol were 0.61 to 1.378 mmol/L).  Additional adverse reactions included gradual neurological deterioration, seizures, intracranial hemorrhage, hematologic abnormalities, skin breakdown, hepatic and renal failure, hypotension, bradycardia, and cardiovascular collapse. Preterm, low-birth weight infants may be more likely to develop these reactions because they may be less able to metabolize benzyl alcohol.

    When prescribing BLINCYTO (with preservative) in pediatric patients, consider the combined daily metabolic load of benzyl alcohol from all sources including BLINCYTO (with preservative) (contains 7.4 mg of benzyl alcohol per mL) and other drugs containing benzyl alcohol. The minimum amount of benzyl alcohol at which serious adverse reactions may occur is not known [see Warnings and Precautions (5.12)].

    Due to the addition of bacteriostatic saline, 7-day infusion bags of BLINCYTO solution contain benzyl alcohol and are not recommended for use in patients weighing less than 22 kg. Prepare BLINCYTO solution for infusion with preservative-free saline in 24-hour or 48-hour infusion bags for patients weighing less than 22 kg [see Dosage and Administration (2.5)].

    8.5       Geriatric Use

    Of the total number of patients with ALL treated in clinical studies of BLINCYTO, approximately 12% were 65 and over, while 2% were 75 and older. No overall differences in safety or effectiveness were observed between these patients and younger patients, and other reported clinical experience has not identified differences in responses between the elderly and younger patients. However, elderly patients experienced a higher rate of serious infections and neurological toxicities, including cognitive disorder, encephalopathy, and confusion [see Warnings and Precautions (5.2, 5.3)].

  • 10       OVERDOSAGE

    Overdoses have been observed, including one adult patient who received 133-fold the recommended therapeutic dose of BLINCYTO delivered over a short duration.

    In the dose evaluation phase of a study in pediatric and adolescent patients with relapsed or refractory B-cell precursor ALL, one patient experienced a fatal cardiac failure event in the setting of life-threatening cytokine release syndrome (CRS) at a 30 mcg/m2/day (higher than the maximum tolerated/recommended) dose [see Warnings and Precautions (5.1) and Adverse Reactions (6)].

    Overdoses resulted in adverse reactions, which were consistent with the reactions observed at the recommended dosage and included fever, tremors, and headache. In the event of overdose, interrupt the infusion, monitor the patient for signs of adverse reactions, and provide supportive care [see Warnings and Precautions (5.10)]. Consider re-initiation of BLINCYTO at the recommended dosage when all adverse reactions have resolved and no earlier than 12 hours after interruption of the infusion [see Dosage and Administration (2.1)].

  • 12       CLINICAL PHARMACOLOGY

    12.1       Mechanism of Action

    Blinatumomab is a bispecific CD19-directed CD3 T-cell engager that binds to CD19 expressed on the surface of cells of B-lineage origin and CD3 expressed on the surface of T cells. It activates endogenous T cells by connecting CD3 in the T-cell receptor (TCR) complex with CD19 on benign and malignant B cells. Blinatumomab mediates the formation of a synapse between the T-cell and the tumor cell, upregulation of cell adhesion molecules, production of cytolytic proteins, release of inflammatory cytokines, and proliferation of T cells, which result in redirected lysis of CD19+ cells.

    12.2       Pharmacodynamics

    During the continuous intravenous infusion over 4 weeks, the pharmacodynamic response was characterized by T-cell activation and initial redistribution, reduction in peripheral B cells, and transient cytokine elevation.

    Peripheral T-cell redistribution (i.e., T-cell adhesion to blood vessel endothelium and/or transmigration into tissue) occurred after start of BLINCYTO infusion or dose escalation. T-cell counts initially declined within 1 to 2 days and then returned to baseline levels within 7 to 14 days in the majority of patients. Increase of T-cell counts above baseline (T-cell expansion) was observed in few patients.

    Peripheral B-cell counts decreased to less than or equal to 10 cells/microliter during the first treatment cycle at doses ≥ 5 mcg/m2/day or ≥ 9 mcg/day in the majority of patients. No recovery of peripheral B-cell counts was observed during the 2-week BLINCYTO-free period between treatment cycles. Incomplete depletion of B cells occurred at doses of 0.5 mcg/m2/day and 1.5 mcg/m2/day and in a few patients at higher doses.

    Cytokines including IL-2, IL-4, IL-6, IL-8, IL-10, IL-12, TNF-α, and IFN-γ were measured, and IL-6, IL-10, and IFN-γ were elevated. The highest elevation of cytokines was observed in the first 2 days following start of BLINCYTO infusion. The elevated cytokine levels returned to baseline within 24 to 48 hours during the infusion. In subsequent treatment cycles, cytokine elevation occurred in fewer patients with lesser intensity compared to the initial 48 hours of the first treatment cycle.

    12.3       Pharmacokinetics

    The pharmacokinetics of blinatumomab appear linear over a dose range from 5 to 90 mcg/m2/day (approximately equivalent to 9 to 162 mcg/day) in adult patients. Following continuous intravenous infusion, the steady-state serum concentration (Css) was achieved within a day and remained stable over time. The increase in mean Css values was approximately proportional to the dose in the range tested. At the clinical doses of 9 mcg/day and 28 mcg/day for the treatment of relapsed or refractory ALL, the mean (SD) Css was 228 (356) pg/mL and 616 (537) pg/mL, respectively.

    Distribution
    The estimated mean (SD) volume of distribution based on terminal phase (Vz) was 4.35 (2.45) L with continuous intravenous infusion of blinatumomab.

    Metabolism
    The metabolic pathway of blinatumomab has not been characterized. Like other protein therapeutics, BLINCYTO is expected to be degraded into small peptides and amino acids via catabolic pathways.

    Elimination
    The estimated mean (SD) systemic clearance with continuous intravenous infusion in patients receiving blinatumomab in clinical studies was 3.11 (2.98) L/hour. The mean (SD) half-life was 2.10 (1.41) hours. Negligible amounts of blinatumomab were excreted in the urine at the tested clinical doses.

    Gender, Age, and Body Surface Area
    Results of population pharmacokinetic analyses indicate that age (0.62 to 80 years of age) and gender do not influence the pharmacokinetics of blinatumomab. Body surface area (0.4 to 2.70 m2) influences the pharmacokinetics of blinatumomab, however, the clinical relevance of this effect is unknown.

    Hepatic Impairment
    No formal pharmacokinetic studies using BLINCYTO have been conducted in patients with hepatic impairment.

    Renal Impairment
    No formal pharmacokinetic studies of blinatumomab have been conducted in patients with renal impairment.

    Pharmacokinetic analyses showed an approximately 2-fold difference in mean blinatumomab clearance values between patients with moderate renal impairment (CrCL ranging from 30 to 59 mL/min, N = 21) and normal renal function (CrCL more than 90 mL/min, N = 215). However, high interpatient variability was discerned (CV% up to 96.8%), and clearance values in renal impaired patients were essentially within the range observed in patients with normal renal function. There is no information available in patients with severe renal impairment (CrCL less than 30 mL/min) or patients on hemodialysis.

    Drug Interactions
    Transient elevation of cytokines may suppress CYP450 enzyme activities [see Drug Interactions (7) and Clinical Pharmacology (12.2)]. 

    Specific Populations
    Pediatrics

    The pharmacokinetics of blinatumomab appear linear over a dose range from 5 to 30 mcg/m2/day in pediatric patients. At the recommended doses, the mean (SD) steady-state concentration (Css) values were 162 (179) and 533 (392) pg/mL at 5 and 15 mcg/m2/day doses, respectively.  The estimated mean (SD) volume of distribution (Vz), clearance (CL), and terminal half-life (t1/2,z) were 3.14 (2.97) L/m2, 1.88 (1.90) L/hour/m2, and 2.04 (1.35) hours, respectively. 

  • 13       NONCLINICAL TOXICOLOGY

    13.1       Carcinogenesis, Mutagenesis, Impairment of Fertility

    No carcinogenicity or genotoxicity studies have been conducted with blinatumomab.

    No studies have been conducted to evaluate the effects of blinatumomab on fertility. A murine surrogate molecule had no adverse effects on male and female reproductive organs in a 13-week repeat-dose toxicity study in mice.

  • 14       CLINICAL STUDIES

    14.1       MRD-positive B-cell Precursor ALL 

    BLAST Study

    The efficacy of BLINCYTO was evaluated in an open-label, multicenter, single-arm study (BLAST Study) [NCT01207388] that included patients who were ≥ 18 years of age, had received at least 3 chemotherapy blocks of standard ALL therapy, were in hematologic complete remission (defined as < 5% blasts in bone marrow, absolute neutrophil count > 1 Gi/L, platelets > 100 Gi/L) and had MRD at a level of ≥ 0.1% using an assay with a minimum sensitivity of 0.01%. BLINCYTO was administered at a constant dose of 15 mcg/m2/day (equivalent to the recommended dosage of 28 mcg/day) intravenously for all treatment cycles. Patients received up to 4 cycles of treatment. Dose adjustment was possible in case of adverse events.

    The treated population included 86 patients in first or second hematologic complete remission (CR1 or CR2). The demographics and baseline characteristics are shown in Table 12. The median number of treatment cycles was 2 (range: 1 to 4). Following treatment with BLINCYTO, 45 out of 61 (73.8%) patients in CR1 and 14 out of 25 (56.0%) patients in CR2 underwent allogeneic hematopoietic stem cell transplantation in continuous hematologic complete remission.

    Efficacy was based on achievement of undetectable MRD within one cycle of BLINCYTO treatment and hematological relapse-free survival (RFS). The assay used to assess MRD response had a sensitivity of 0.01% for 6 patients and ≤ 0.005% for 80 patients. Overall, undetectable MRD was achieved by 70 patients (81.4%: 95% CI: 71.6%, 89.0%). The median hematological RFS was 22.3 months. Table 12 shows the MRD response and hematological RFS by remission number.

    14.2       Relapsed/Refractory B-cell Precursor ALL

    TOWER Study

    The efficacy of BLINCYTO was compared to standard of care (SOC) chemotherapy in a randomized, open-label, multicenter study (TOWER Study) [NCT02013167]. Eligible patients were ≥ 18 years of age with relapsed or refractory B-cell precursor ALL [> 5% blasts in the bone marrow and refractory to primary induction therapy or refractory to last therapy, untreated first relapse with first remission duration < 12 months, untreated second or later relapse, or relapse at any time after allogeneic hematopoietic stem cell transplantation (alloHSCT)]. BLINCYTO was administered at 9 mcg/day on Days 1-7 and 28 mcg/day on Days 8-28 for Cycle 1, and 28 mcg/day on Days 1-28 for Cycles 2-5 in 42-day cycles and for Cycles 6-9 in 84-day cycles. Dose adjustment was possible in case of adverse events. SOC chemotherapy included fludarabine, cytarabine arabinoside, and granulocyte colony-stimulating factor (FLAG); high-dose cytarabine arabinoside (HiDAC); high-dose methotrexate- (HDMTX) based combination; or clofarabine/clofarabine-based regimens.

    There were 405 patients randomized 2:1 to receive BLINCYTO or investigator-selected SOC chemotherapy. Randomization was stratified by age (< 35 years vs. ≥ 35 years of age), prior salvage therapy (yes vs. no), and prior alloHSCT (yes vs. no) as assessed at the time of consent. The demographics and baseline characteristics were well-balanced between the two arms (see Table 13).

    Of the 271 patients randomized to the BLINCYTO arm, 267 patients received BLINCYTO treatment. The median number of treatment cycles was two (range: 1 to 9 cycles); 267 (99%) received Cycles 1-2 (induction), 86 (32%) received Cycles 3-5 (consolidation), and 27 (10%) received Cycles 6-9 (continued therapy).  Of the 134 patients on the SOC arm, 25 dropped out prior to start of study treatment, and 109 patients received a median of 1 treatment cycle (range: 1 to 4 cycles).  

    The determination of efficacy was based on overall survival (OS). The study demonstrated statistically significant improvement in OS for patients treated with BLINCYTO as compared to SOC chemotherapy.

    Study MT103-211

    Study MT103-211 [NCT01466179] was an open-label, multicenter, single-arm study. Eligible patients were ≥ 18 years of age with Philadelphia chromosome-negative relapsed or refractory B-cell precursor ALL (relapsed with first remission duration of ≤ 12 months in first salvage or relapsed or refractory after first salvage therapy or relapsed within 12 months of alloHSCT, and had ≥ 10% blasts in bone marrow).

    BLINCYTO was administered as a continuous intravenous infusion. The recommended dose for this study was determined to be 9 mcg/day on Days 1-7 and 28 mcg/day on Days 8-28 for Cycle 1, and 28 mcg/day on Days 1-28 for subsequent cycles. Dose adjustment was possible in case of adverse events. The treated population included 185 patients who received at least 1 infusion of BLINCYTO; the median number of treatment cycles was 2 (range: 1 to 5). Patients who responded to BLINCYTO but later relapsed had the option to be retreated with BLINCYTO. Among treated patients, the median age was 39 years (range: 18 to 79 years), 63 out of 185 (34.1%) had undergone HSCT prior to receiving BLINCYTO, and 32 out of 185 (17.3%) had received more than 2 prior salvage therapies.

    Efficacy was based on the complete remission (CR) rate, duration of CR, and proportion of patients with an MRD-negative CR/CR with partial hematological recovery (CR/CRh*) within 2 cycles of treatment with BLINCYTO. Table 15 shows the efficacy results from this study. The HSCT rate among those who achieved CR/CRh* was 39% (30 out of 77).

    ALCANTARA Study

    The efficacy of BLINCYTO for treatment of Philadelphia chromosome-positive B-cell precursor ALL was evaluated in an open-label, multicenter, single-arm study (ALCANTARA Study) [NCT02000427]. Eligible patients were ≥ 18 years of age with Philadelphia chromosome-positive B-cell precursor ALL, relapsed or refractory to at least 1 second generation or later tyrosine kinase inhibitor (TKI), or intolerant to second generation TKI, and intolerant or refractory to imatinib mesylate.

    BLINCYTO was administered at 9 mcg/day on Days 1-7 and 28 mcg/day on Days 8-28 for Cycle 1, and 28 mcg/day on Days 1-28 for subsequent cycles. Dose adjustment was possible in case of adverse events.

    The treated population included 45 patients who received at least one infusion of BLINCYTO; the median number of treatment cycles was 2 (range: 1 to 5). The demographics and baseline characteristics are shown in Table 16.

    Efficacy was based on the complete remission (CR) rate, duration of CR, and proportion of patients with an MRD-negative CR/CR with partial hematological recovery (CR/CRh*) within 2 cycles of treatment with BLINCYTO. Table 17 shows the efficacy results from ALCANTARA Study. Five of the 16 responding (31%) patients underwent allogeneic HSCT in CR/CRh* induced with BLINCYTO. There were 10 patients with documented T315I mutation; four achieved CR within 2 cycles of treatment with BLINCYTO.

    Study MT103-205

    Study MT103-205 [NCT01471782]  was an open-label, multicenter, single-arm study in pediatric patients with relapsed or refractory B-cell precursor ALL (second or later bone marrow relapse, any marrow relapse after allogeneic HSCT, or refractory to other treatments, and had > 25% blasts in bone marrow). BLINCYTO was administered at 5 mcg/m2/day on Days 1-7 and 15 mcg/m2/day on Days 8-28 for Cycle 1, and 15 mcg/m2/day on Days 1-28 for subsequent cycles. Dose adjustment was possible in case of adverse events. Patients who responded to BLINCYTO but later relapsed had the option to be retreated with BLINCYTO. 

    Among the 70 treated patients, the median age was 8 years (range: 7 months to 17 years), 40 out of 70 (57.1%) had undergone allogeneic HSCT prior to receiving BLINCYTO, and 39 out of 70 (55.7%) had refractory disease. The median number of treatment cycles was 1 (range: 1 to 5).

    Twenty-three out of 70 (32.9%) patients achieved CR/CRh* within the first 2 treatment cycles with 17 out of 23 (73.9%) occurring within Cycle 1 of treatment. See Table 18 for the efficacy results from the study. The HSCT rate among those who achieved CR/CRh* was 48% (11 out of 23).

    What is BLINCYTO?
    BLINCYTO is a prescription medicine used to treat adults and children with:
    • B-cell precursor acute lymphoblastic leukemia (ALL) in remission with molecular evidence of leukemia
    • B-cell precursor ALL that has come back or did not respond to previous treatments
    ALL is a cancer of the blood in which a particular kind of white blood cell is growing out of control.
    Who should not receive BLINCYTO?
    Do not receive BLINCYTO if you are allergic to blinatumomab or to any of the ingredients of BLINCYTO. See the end of this Medication Guide for a complete list of ingredients in BLINCYTO.
    Before receiving BLINCYTO, tell your healthcare provider about all of your medical conditions, including if you or your child:
    • have a history of neurological problems, such as seizures, confusion, trouble speaking or loss of balance
    • have an infection
    • have ever had an infusion reaction after receiving BLINCYTO or other medications
    • have a history of radiation treatment to the brain, or chemotherapy treatment
    • are scheduled to receive a vaccine. You should not receive a “live vaccine” within 2 weeks before you start treatment with BLINCYTO, during treatment, and until your immune system recovers after you receive your last cycle of BLINCYTO. If you are not sure about the type of vaccine, ask your healthcare provider.
    • are pregnant or plan to become pregnant. BLINCYTO may harm your unborn baby. Tell your healthcare provider if you become pregnant during treatment with BLINCYTO.
      • If you are able to become pregnant, your healthcare provider should do a pregnancy test before you start treatment with BLINCYTO.
      • Females who are able to become pregnant should use an effective form of birth control during treatment with BLINCYTO, and for at least 48 hours after the last dose of BLINCYTO.

    • are breastfeeding or plan to breastfeed. It is not known if BLINCYTO passes into your breast milk. You should not breastfeed during treatment with BLINCYTO and for at least 48 hours after your last treatment. 
    Tell your healthcare provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements.
    How will I receive BLINCYTO?
    • BLINCYTO will be given to you by intravenous (IV) infusion into your vein by an infusion pump.
    • Your healthcare provider will decide the number of treatment cycles of BLINCYTO.
      • You will receive BLINCYTO by continuous IV infusion for 4 weeks (28 days), followed by a 2 week (14 days) break during which you will not receive BLINCYTO. This is 1 treatment cycle (42 days).

    • Your healthcare provider may prescribe continued therapy.
      • You will receive BLINCYTO by continuous IV infusion for 4 weeks (28 days), followed by an 8 week (56 days) break during which you will not receive BLINCYTO. This is 1 treatment cycle (84 days).

    • Your healthcare provider may give you BLINCYTO in a hospital or clinic for the first 3 to 9 days of the first treatment cycle and for the first 2 days of the second cycle to check you for side effects. If you receive additional treatment cycles of BLINCYTO or if your treatment is stopped for a period of time and restarted, you may also be treated in a hospital or clinic.
    • Your healthcare provider may change your dose of BLINCYTO, delay, or completely stop treatment with BLINCYTO if you have certain side effects.
    • Your healthcare provider will do blood tests during treatment with BLINCYTO to check you for side effects.
    • Before you receive BLINCYTO, you will be given a corticosteroid medicine to help reduce infusion reactions.
    • It is very important to keep the area around the IV catheter clean to reduce the risk of getting an infection. Your healthcare provider will show you how to care for your catheter site.
    • Do not change the settings on your infusion pump, even if there is a problem with your pump or your pump alarm sounds. Any changes to your infusion pump settings may cause a dose that is too high or too low to be given.  
    Call your healthcare provider or nurse right away if you have any problems with your pump or your pump alarm sounds.
    What should I avoid while receiving BLINCYTO?
    Do not drive, operate heavy machinery, or do other dangerous activities while you are receiving BLINCYTO because BLINCYTO can cause neurological symptoms, such as dizziness, seizures, and confusion.
    What are the possible side effects of BLINCYTO?
    BLINCYTO may cause serious side effects, including:
    See “What is the most important information I should know about BLINCYTO?”
    • Infections. BLINCYTO may cause life-threatening infections that may lead to death. Tell your healthcare provider right away if you develop any signs or symptoms of an infection.
    • Low white blood cell counts (neutropenia). Neutropenia is common with BLINCYTO treatment and may sometimes be life-threatening. Low white blood cell counts can increase your risk of infection. Your healthcare provider will do blood tests to check your white blood cell count during treatment with BLINCYTO. Tell your healthcare provider right away if you get a fever.
    • Abnormal liver blood tests. Your healthcare provider will do blood tests to check your liver before you start BLINCYTO and during treatment with BLINCYTO.
    • Inflammation of the pancreas (pancreatitis). Pancreatitis may happen in people treated with BLINCYTO and corticosteroids. It may be severe and lead to death. Tell your healthcare provider right away if you have severe stomach-area pain that does not go away. The pain may happen with or without nausea and vomiting.
    The most common side effects of BLINCYTO include:
    • infections
    • low platelet count (thrombocytopenia)
    • fever
    • reactions related to infusion of the medicine such as face swelling, low blood pressure, and high blood pressure (infusion-related reactions)
    • headache
    • low red blood cell count (anemia)
    These are not all the possible side effects of BLINCYTO.
    Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.
