Pharmacology

Brexucabtagene autoleucel is a CD19-directed genetically modified autologous T-cell immunotherapy in which a patient's T cells are reprogrammed with a transgene encoding a chimeric antigen receptor (CAR) to identify and eliminate CD19-expressing malignant and normal cells. The CAR is comprised of a murine single-chain antibody fragment which recognizes CD19 and is fused to CD28 and CD3 zeta. CD3 zeta is a critical component for initiating T-cell activation and antitumor activity. After binding to CD19-expressing cells, the CD28 and CD3-zeta costimulatory domains activate downstream signaling cascades, which results in T-cell activation, proliferation, acquisition of effector functions, and secretion of inflammatory cytokines and chemokines, leading to destruction of CD19-expressing cells. Brexucabtagene autoleucel is prepared from the patient's peripheral blood cells obtained via leukapheresis.

Reconstitution

Do not remove the infusion bag from the cassette if the information on the cassette label does not match the intended patient. Inspect patient-specific infusion bag for breaches in container integrity (such as breaks or cracks) prior to thawing (if bag is compromised, contact manufacturer). Place infusion bag inside a second sterile bag. Thaw at ~37°C (~98.6°F) using a water bath or dry thaw method until there is no visible ice in the infusion bag. Gently mix contents of the thawed infusion bag to disperse cellular material clumps; inspect for visible cell clumps; if visible cell clumps remain, gently mix the contents of the bag (small clumps of cellular material should disperse with gentle manual mixing). Do not wash, spin down, and/or re-suspend brexucabtagene autoleucel in new media prior to infusion. Brexucabtagene autoleucel contains human blood cells that are genetically modified with replication incompetent retroviral vector. Follow universal precautions and local biosafety guidelines for handling and disposal.

Administration

IV: For IV use only. Administer in a health care facility. For autologous use only. Coordinate the timing of administration with thawing (may be stored for up to 3 hours at room temperature after thawing); infusion start time may need to be adjusted based on thawing.

Prime the tubing with NS prior to infusion. Infuse entire contents of bag within 30 minutes either by gravity or a peristaltic pump (infusion bag volume is ~68 mL). A central line is preferred for infusion. Gently agitate the bag during infusion to prevent cell clumping. After completion of the infusion, rinse the tubing with NS at the same infusion rate to ensure complete cell product delivery. Do not use a leukodepleting filter.

Prior to administration: Ensure tocilizumab and emergency equipment are available prior to infusion and during recovery period. Premedicate with acetaminophen and diphenhydramine (or another H₁-antagonist) ~30 to 60 minutes prior to brexucabtagene autoleucel infusion. Avoid prophylactic systemic corticosteroids because they may interfere with the brexucabtagene autoleucel activity. Confirm patient identity and match to patient identifiers on the infusion cassette and bag. Inspect the contents of the thawed infusion bag for visible cell clumps; if visible cell clumps remain, gently mix the contents of the bag (small clumps of cellular material should disperse with gentle manual mixing). Do not infuse if clumps are not dispersed, if the infusion bag is damaged or leaking, or if it otherwise appears to be compromised. Apply universal precautions for product handling. Monitor patient daily at the healthcare facility for at least 7 days after cell infusion; patient should remain within proximity of the facility for at least 4 weeks after infusion.

Storage

Store frozen suspension in the vapor phase of liquid nitrogen (-150°C or less [-238°F or less]). After thawing, may be stored for up to 3 hours at room temperature of 20°C to 25°C (68°F to 77°F).

Warnings/Precautions

Concerns related to adverse effects:

• Cytokine release syndrome: [US Boxed Warning]: Cytokine release syndrome (CRS), including life-threatening reactions, occurred in patients receiving brexucabtagene autoleucel. Do not administer brexucabtagene autoleucel to patients with active infection or inflammatory disorders. Treat severe or life-threatening CRS with tocilizumab or tocilizumab and corticosteroids. CRS occurred in the majority of patients receiving brexucabtagene autoleucel; grade 3 and higher events were reported, including a fatal CRS event. The median time to onset of CRS was 3 days (range: 1 to 13 days); the median duration of CRS was 10 days (range: 1 to 50 days). Key manifestations of CRS include fever, hypotension, hypoxia, chills, tachycardia, headache, fatigue, nausea, AST or ALT increases, and diarrhea; acute kidney injury may also occur. Ensure that tocilizumab is available (a minimum of 2 doses for each patient) on site prior to brexucabtagene autoleucel infusion. Monitor for signs or symptoms of CRS for at least 4 weeks after treatment (monitor daily at the health care facility for the first 7 days following the infusion). Patients should seek immediate medical attention if signs or symptoms of CRS occur at any time. Evaluate patients immediately at the first sign of CRS; begin supportive care, tocilizumab, and/or corticosteroids as indicated.

• Cytopenias: Prolonged cytopenias may occur for several weeks after lymphodepleting chemotherapy and brexucabtagene autoleucel infusion. Unresolved (by day 30 following brexucabtagene autoleucel treatment) grade 3 and 4 cytopenias included thrombocytopenia, neutropenia, and anemia. Monitor blood counts.

• Hepatitis B virus reactivation: Hepatitis B virus (HBV) reactivation (sometimes resulting in fulminant hepatitis, hepatic failure, and death) can occur in patients treated with medications directed against B cells. Screen for HBV, hepatitis C virus, and HIV in accordance with clinical guidelines prior to collection of cells for manufacturing.

• Hypersensitivity: Serious hypersensitivity reactions, including anaphylaxis, may occur due to the dimethyl sulfoxide or residual gentamicin in brexucabtagene autoleucel.

• Hypogammaglobulinemia: Hypogammaglobulinemia and B-cell aplasia may occur in patients receiving brexucabtagene autoleucel. Monitor immunoglobulin levels after brexucabtagene autoleucel treatment. Manage hypogammaglobulinemia with infection precautions, antibiotic prophylaxis, and immunoglobulin replacement treatment (per standard replacement guidelines).

• Infection: Serious infections (including life-threatening infections) have occurred. Infections occurred in ~50% of patients after brexucabtagene autoleucel infusion, including grades 3 and higher infections in 30% of patients. Bacterial, viral, and fungal infections were reported. Begin prophylaxis according to local guidelines prior to brexucabtagene autoleucel infusion. Monitor for signs and symptoms of infection before and following treatment and manage appropriately; do not administer to patients with clinically significant active systemic infections. Neutropenic fever has been observed after brexucabtagene autoleucel infusion and may occur concurrently with CRS. If neutropenic fever occurs, evaluate for infection and manage with broad-spectrum antibiotics, fluids, and other supportive care as clinically indicated.

• Neurologic toxicities: [US Boxed Warning]: Neurologic toxicities, including life-threatening reactions, occurred in patients receiving brexucabtagene autoleucel, including concurrently with CRS or after CRS resolution. Monitor for neurologic toxicities after treatment with brexucabtagene autoleucel. Provide supportive care and/or corticosteroids as needed. Neurologic events occurred in ~80% of patients receiving brexucabtagene autoleucel; grade 3 or higher events were observed. The median time to onset was 6 days (range: 1 to 32 days). The median duration of neurologic toxicities was 21 days (range: 2 to 454 days) in most patients; neurologic toxicity resolved in close to 80% of patients, although persisted (usually at grade 1 or 2) in some patients. Over one-half of patients experienced CRS before neurologic toxicity onset; some patients did not experience CRS with neurologic events, and others developed neurological events after CRS resolution. The majority of patients experienced the first CRS or neurological events within the first 7 days after brexucabtagene autoleucel infusion. The most common neurologic events were encephalopathy, headache, tremor, aphasia, and delirium; serious events included encephalopathy, aphasia, and seizures. Monitor for signs or symptoms of neurologic toxicities for at least 4 weeks after treatment (monitor daily at the healthcare facility for the first 7 days following the infusion). Treat promptly if neurologic toxicities occur. Due to the potential for neurologic events, including altered mental status or seizures, patients receiving brexucabtagene autoleucel are at risk for altered or decreased consciousness or coordination in the 8 weeks following administration; during this initial period, advise patients to refrain from driving and engaging in hazardous occupations or activities, such as operating heavy or potentially dangerous machinery.

• Secondary malignancy: Patients treated with brexucabtagene autoleucel may develop secondary malignancies. Monitor (life-long) for secondary malignancies. If a secondary malignancy occurs, contact the manufacturer (1-844-454-5483) to obtain patient sampling instructions for testing.

Concurrent drug therapy issues:

• Drug-drug interactions: Potentially significant interactions may exist, requiring dose or frequency adjustment, additional monitoring, and/or selection of alternative therapy. Consult drug interactions database for more detailed information.

• Immunizations: Vaccination with live virus vaccines is not recommended for at least 6 weeks prior to the start of lymphodepleting chemotherapy, during brexucabtagene autoleucel treatment, and until immune recovery following treatment. The safety of immunization with live viral vaccines during or following brexucabtagene autoleucel treatment has not been studied.

Other warnings/precautions:

• Appropriate use: For autologous use only. Confirm patient identity and match to patient identifiers on the cassette and infusion bag prior to infusion. Administer in a health care facility; patients should remain within proximity of the facility for at least 4 weeks after infusion.

• REMS program: [US Boxed Warning]: Brexucabtagene autoleucel is available only through a restricted program under a Risk Evaluation and Mitigation Strategy (REMS) called the YESCARTA and TECARTUS REMS. Information is available at https://www.YescartaTecartusREMS.com or 1-844-454-5483.

Monitoring Parameters

Screen for hepatitis B virus, hepatitis C virus, and HIV (prior to collection of cells for manufacturing). Monitor immunoglobulin levels and blood counts (after treatment). Evaluate pregnancy status prior to use in females of reproductive potential.

Monitor for signs/symptoms of cytokine release syndrome (CRS) and neurological toxicities for at least 4 weeks after treatment (monitor daily for the first 7 days after infusion at the health care facility; patients with ≥ grade 2 CRS or ≥ grade 2 neurologic toxicity should be monitored with continuous cardiac telemetry and pulse oximetry), monitor for hypersensitivity reactions and for signs/symptoms of infection or neutropenic fever. Monitor (life-long) for secondary malignancies.

Reproductive Considerations

Evaluate pregnancy status prior to use in females of reproductive potential. Females of reproductive potential who are sexually active should have a negative pregnancy test prior to initiating brexucabtagene autoleucel therapy. Consider contraception recommendations of concomitant therapy; the duration of effective contraception specific to brexucabtagene autoleucel treatment is not known.

Pregnancy Considerations
