Drug: Blincyto
BLINCYTO (blinatumomab) is a bispecific CD19-directed CD3 T-cell engager that binds to CD19 (expressed on cells of B-lineage origin) and CD3 (expressed on T cells). BLINCYTO is produced in Chinese hamster ovary cells. It consists of 504 amino acids and has a molecular weight of approximately 54 kilodaltons. Each BLINCYTO package contains 1 vial BLINCYTO and 1 vial IV Solution Stabilizer. BLINCYTO is supplied in a single-use vial as a sterile, preservative-free, white to off-white lyophilized powder for intravenous administration. Each single-use vial of BLINCYTO contains 35 mcg blinatumomab, citric acid monohydrate (3.35 mg), lysine hydrochloride (23.23 mg), polysorbate 80 (0.64 mg), trehalose dihydrate (95.5 mg), and sodium hydroxide to adjust pH to 7.0. After reconstitution with 3 mL of preservative-free Sterile Water for Injection, USP, the resulting concentration is 12.5 mcg/mL blinatumomab. IV Solution Stabilizer is supplied in a single-use vial as a sterile, preservative-free, colorless to slightly yellow, clear solution. Each single-use vial of IV Solution Stabilizer contains citric acid monohydrate (52.5 mg), lysine hydrochloride (2283.8 mg), polysorbate 80 (10 mg), sodium hydroxide to adjust pH to 7.0, and water for injection.

2 Diarrhea includes the following terms: colitis, diarrhea, enteritis, and neutropenic colitis.
3 Tremor includes the following terms: resting tremor and tremor.
4 Dyspnea includes the following terms: acute respiratory failure, bronchial hyperactivity, bronchospasm, dyspnea, dyspnea exertional, respiratory distress, respiratory failure, and wheezing.
5 Rash includes the following terms: erythema, rash, erythematous rash, generalized rash, macular rash, maculopapular rash, papular rash, and vesicular rash. Additional important adverse reactions that did not meet the threshold criteria for inclusion in Table 2 were: Blood and lymphatic system disorders: leukocytosis (2%), lymphopenia (1%) Cardiac disorders: tachycardia (8%) General disorders and administration site conditions: edema (5%) Immune system disorders: cytokine storm (1%) Investigations: decreased immunoglobulins (9%), increased blood bilirubin (8%), increased gammaglutamyl- transferase (6%), increased liver enzymes (1%) Metabolism and nutrition disorders: tumor lysis syndrome (4%), hypoalbuminemia (4%) Nervous system disorders: encephalopathy (5%), paresthesia (5%), aphasia (4%), convulsion (2%), memory impairment (2%), cognitive disorder (1%), speech disorder ( < 1%) Psychiatric disorders: confusion (7%), disorientation (3%) Vascular disorders: capillary leak syndrome ( < 1%). Hypersensitivity reactions related to BLINCYTO treatment were hypersensitivity (1%) and bronchospasm ( < 1%). Immunogenicity As with all therapeutic proteins, there is potential for immunogenicity. 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 1% of patients treated with BLINCYTO tested positive for binding antiblinatumomab antibodies. All patients who tested positive for binding antibodies also tested positive for neutralizing anti-blinatumomab antibodies. Anti-blinatumomab antibody formation may affect pharmacokinetics of BLINCYTO. No association was seen between antibody development and development of adverse events. 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. The detection of anti-blinatumomab 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.

† Storage time includes infusion time. If IV bag containing BLINCYTO solution for infusion is not administered within the time frames and temperatures indicated, it must be discarded; it should not be refrigerated again.
- A single cycle of treatment of BLINCYTO consists of 4 weeks of continuous intravenous infusion followed by a 2-week treatment-free interval.
- For patients at least 45 kg in weight:
- In Cycle 1, administer BLINCYTO at 9 mcg/day on Days 1–7 and at 28 mcg/day on Days 8–28.
- For subsequent cycles, administer BLINCYTO at 28 mcg/day on Days 1–28.
- Allow for at least 2 weeks treatment-free between cycles of BLINCYTO.
- A treatment course consists of up to 2 cycles of BLINCYTO for induction followed by 3 additional cycles for consolidation treatment (up to a total of 5 cycles).
- Premedicate with dexamethasone 20 mg intravenously 1 hour prior to the first dose of BLINCYTO of each cycle, prior to a step dose (such as Cycle 1 day 8), or when restarting an infusion after an interruption of 4 or more hours.
- 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.
- BLINCYTO infusion bags should be infused over 24 hours or 48 hours [see Reconstitution and Preparation of Solution for Infusion]. Infuse the total 240 mL BLINCYTO solution according to the instructions on the pharmacy label on the bag at one of the following constant infusion rates:
- Infusion rate of 10 mL/h for a duration of 24 hours, OR
- Infusion rate of 5 mL/h for a duration of 48 hours
- The BLINCYTO solution for infusion must be administered using IV tubing that contains a sterile, non-pyrogenic, low protein-binding, 0.2 micron in-line filter.
- Important Note: Do not flush the infusion line, especially when changing infusion bags. Flushing when changing bags or at completion of infusion can result in excess dosage. BLINCYTO should be infused through a dedicated lumen.
- At the end of the infusion, any unused BLINCYTO solution in the IV bag and IV lines should be disposed of in accordance with local requirements.
- 1 package of BLINCYTO for preparation of 9 mcg/day dose infused over 24 hours at a rate of 10 mL/h, 9 mcg/day dose infused over 48 hours at a rate of 5 mL/h, and 28 mcg/day dose infused over 24 hours at a rate of 10 mL/h
- 2 packages of BLINCYTO for preparation of 28 mcg/day dose infused over 48 hours at a rate of 5 mL/h

- Personnel should be appropriately trained in aseptic manipulations and admixing of oncology drugs.
- Personnel should wear appropriate protective clothing and gloves.
- Gloves and surfaces should be disinfected.
- IV Solution Stabilizer is provided with the BLINCYTO package and is used to coat the prefilled IV bag prior to addition of reconstituted BLINCYTO to prevent adhesion of BLINCYTO to IV bags and IV lines. Therefore, add IV Solution Stabilizer to the IV bag containing 0.9% Sodium Chloride. Do not use IV Solution Stabilizer for reconstitution of BLINCYTO.
- The entire volume of the admixed BLINCYTO will be more than the volume administered to the patient (240 mL) to account for the priming of the IV line and to ensure that the patient will receive the full dose of BLINCYTO.
- When preparing an IV bag, remove air from IV bag. This is particularly important for use with an ambulatory infusion pump.
- Use the specific volumes described in the admixing instructions [see Preparation of BLINCYTO Solution for Infusion Using a Prefilled 250 mL 0.9% Sodium Chloride IV Bag] to minimize errors in calculation.

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 drugdrug 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 (eg, warfarin) or drug concentrations (eg, cyclosporine). Adjust the dose of the concomitant drug as needed [see CLINICAL PHARMACOLOGY].

Overdoses have been observed, including one patient who received 133-fold the recommended therapeutic dose of BLINCYTO delivered over a short duration. Overdoses resulted in adverse reactions which were consistent with the reactions observed at the recommended therapeutic dose and included fever, tremors, and headache. In the event of overdose, interrupt the infusion, monitor the patient for signs of toxicity, and provide supportive care [see WARNINGS AND PRECAUTIONS]. Consider reinitiation of BLINCYTO at the correct therapeutic dose when all toxicities have resolved and no earlier than 12 hours after interruption of the infusion [see DOSAGE AND ADMINISTRATION].

Cytokine Release Syndrome Cytokine Release Syndrome (CRS), which may be life-threatening or fatal, occurred in patients receiving BLINCYTO. Infusion reactions have occurred with the BLINCYTO infusion and may be clinically indistinguishable from manifestations of CRS. Serious adverse events that may be associated with CRS included pyrexia, headache, nausea, asthenia, hypotension, increased alanine aminotransferase, increased aspartate aminotransferase, and increased total bilirubin; these events infrequently led to BLINCYTO discontinuation. Life-threatening or fatal CRS was infrequently reported in patients receiving BLINCYTO. In some cases, disseminated intravascular coagulation (DIC), capillary leak syndrome (CLS), and hemophagocytic lymphohistiocytosis/macrophage activation syndrome (HLH/MAS) have been reported in the setting of CRS. Patients should be closely monitored for signs or symptoms of these events. Management of these events may require either temporary interruption or discontinuation of BLINCYTO [see DOSAGE AND ADMINISTRATION]. Neurological Toxicities In patients receiving BLINCYTO in clinical trials, neurological toxicities have occurred in approximately 50% of patients. The median time to onset of any neurological toxicity was 7 days. Grade 3 or higher (severe, life-threatening, or fatal) neurological toxicities following initiation of BLINCYTO administration occurred in approximately 15% of patients and included encephalopathy, convulsions, speech disorders, disturbances in consciousness, confusion and disorientation, and coordination and balance disorders. The majority of events resolved following interruption of BLINCYTO, but some resulted in treatment discontinuation. Monitor patients receiving BLINCYTO for signs and symptoms of neurological toxicities, and interrupt or discontinue BLINCYTO as recommended [see DOSAGE AND ADMINISTRATION]. Infections In patients receiving BLINCYTO in clinical trials, 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. 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]. 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. 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 Neurological Toxicities]. 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. Elevated Liver Enzymes Treatment with BLINCYTO was associated with transient elevations in liver enzymes. Although the majority of these events were observed in the setting of CRS, some were observed outside of this setting. For these events, the median time to onset was 15 days. In patients receiving BLINCYTO in clinical trials, Grade 3 or greater elevations in liver enzymes occurred in approximately 6% 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.
