Administration: Adult

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 (mantle cell lymphoma) or 14 days (acute lymphoblastic leukemia) after cell infusion; patient should remain within proximity of the facility for at least 4 weeks after infusion.

Warnings/Precautions

Concerns related to adverse effects:

• Cytokine release syndrome: Cytokine release syndrome (CRS), including fatal or life-threatening reactions, occurred in patients receiving brexucabtagene autoleucel. Manage 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 incidence of CRS (first occurrence) within the first 7 days after brexucabtagene autoleucel infusion was 86% in patients with mantle cell lymphoma or acute lymphoblastic leukemia. The median time to onset of CRS was 3 to 5 days (range: 1 to 13 days); the median duration of CRS was 8 to 10 days (range: 1 to 63 days). Key manifestations of CRS include fever, hypotension, hypoxia, chills, tachycardia, headache, fatigue, and nausea; serious events also included dyspnea. Patients should seek immediate medical attention if signs or symptoms of CRS occur at any time.

• 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.

• Hemophagocytic lymphohistiocytosis/macrophage activation syndrome: Hemophagocytic lymphohistiocytosis/macrophage activation syndrome (HLH/MAS) has occurred following brexucabtagene autoleucel infusion, including grade 3 or 4 events. The median time to onset of HLH/MAS was 8 days (range: 6 to 9 days); the median duration of HLH/MAS was 5 days (range: 2 to 8 days). All patients with HLH/MAS experienced concurrent CRS symptoms and neurologic events after brexucabtagene autoleucel infusion.

• Hepatitis B virus reactivation: Hepatitis B virus reactivation (sometimes resulting in fulminant hepatitis, hepatic failure, and death) may occur in patients treated with medications directed against B cells.

• 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.

• 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. Neutropenic fever has been observed after brexucabtagene autoleucel infusion and may occur concurrently with CRS. Life-threatening and fatal infections, including disseminated fungal infections and viral reactivation (eg, human herpes virus-6 encephalitis, progressive multifocal leukoencephalopathy) have been reported in immunosuppressed patients.

• Neurologic toxicities: Neurologic toxicities, including fatal or life-threatening reactions, occurred in patients receiving brexucabtagene autoleucel. Neurologic events occurred in over 80% of patients receiving brexucabtagene autoleucel; grade 3 or higher events were observed. The median time to onset was 6 to 7 days (range: 1 to 51 days). The median duration of neurologic toxicities was 15 to 21 days (range: 1 to 454 days); neurologic toxicity resolved in close to 90% of patients, although persisted in some patients. The onset of neurologic events may be concurrent with CRS, following CRS resolution, or in the absence of CRS. 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, confusion, aphasia, delirium, dizziness, anxiety, and agitation; serious events included encephalopathy, aphasia, confusion, and seizures. 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. If a secondary malignancy occurs, contact the manufacturer (1-844-454-5483) to obtain patient sampling instructions for testing.

Concurrent drug therapy issues:

• 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: 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.

Reproductive Considerations

Evaluate pregnancy status prior to use in patients who may become pregnant. Sexually active patients who may become pregnant 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

Based on the mechanism of action, in utero exposure to brexucabtagene autoleucel may cause fetal harm.

Breastfeeding Considerations

It is not known if brexucabtagene autoleucel is present in breast milk.

According to the manufacturer, the decision to breastfeed during therapy should consider the risk of infant exposure, the benefits of breastfeeding to the infant, and the benefits of treatment to the mother.

Monitoring Parameters

Screen for hepatitis B virus (HBV), hepatitis C virus, and HIV (prior to collection of cells for manufacturing). Monitor blood counts. Monitor immunoglobulin levels and blood counts (after treatment). Evaluate pregnancy status prior to use in patients who may become pregnant.

Monitor for signs/symptoms of cytokine release syndrome (CRS) and neurological toxicities for at least 4 weeks after treatment (monitor daily for at least the first 7 days [mantle cell lymphoma] or 14 days [acute lymphoblastic leukemia] 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, neutropenic fever, and hemophagocytic lymphohistiocytosis/macrophage activation syndrome. Monitor (life-long) for secondary malignancies.

The American Society of Clinical Oncology HBV screening and management provisional clinical opinion (ASCO [Hwang 2020]) recommends HBV screening with hepatitis B surface antigen, hepatitis B core antibody, total Ig or IgG, and antibody to hepatitis B surface antigen prior to beginning (or at the beginning of) systemic anticancer therapy; do not delay treatment for screening/results. Detection of chronic or past HBV infection requires a risk assessment to determine antiviral prophylaxis requirements, monitoring, and follow-up.

Mechanism of Action

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.

Pharmacokinetics

Note: In mantle cell lymphoma, the number of anti-CD19 chimeric antigen receptor (CAR) T cells in the blood was positively associated with objective response (complete remission or partial remission). The median peak anti-CD19 CAR T cell level in patients with mantle cell lymphoma who responded to therapy was 102.4 cells/mcL (range: 0.2 to 2,590 cells/mcL), compared to 12 cells/mcL (range: 0.2 to 1,364 cells/mcL) in nonresponders. The median peak anti-CD19 CAR T cell level in patients with acute lymphoblastic leukemia who had overall complete remission was 38.4 cells/mcL (range: 1.31 to 1,533.4 cells/mcL) and 424 cells/mcL compared to 0.5 cells/mcL (range: 0 to 183.5 cells/mcL) in patients who had noncomplete remission. The median AUC0-28 was also higher in patients with acute lymphoblastic leukemia who had overall complete remission, compared to patients who had noncomplete remission.

Onset: Mantle cell lymphoma: Median time to initial response: 1 month (range: 0.8 to 3.1 months); median time to complete response: 3 months (range: 0.9 to 9.3 months) (Wang 2020).

Duration: Anti-CD19 CAR T cells displayed an initial rapid expansion followed by a decline to near baseline levels by 3 months and 6 months (post-brexucabtagene autoleucel infusion) in mantle cell lymphoma and acute lymphoblastic leukemia, respectively.

Time to peak: Peak levels of anti-CD19 CAR T cells occurred within the first 15 days after infusion.
