Administration

NOTE: Axicabtagene ciloleucel may carry the risk of transmitting infectious diseases to health care professionals handling the product. Employ universal precautions in handling axicabtagene ciloleucel; follow local biosafety guidelines applicable for disposal.
Emetic Risk
Low
Administer routine antiemetic prophylaxis prior to treatment.

Injectable Administration

Visually inspect the contents of the infusion bag for any breaks or cracks before thawing. Do not infuse the contents if the bag is compromised; follow local guidelines or call Kite Pharma at 1-844-454-5483.

Intravenous Administration

Axicabtagene ciloleucel is for autologous and intravenous use.
Each dose of axicabtagene ciloleucel contains a maximum of 2 X 108 CAR-positive viable T-cells suspended in a single patient-specific infusion bag; the total infusion bag volume is approximately 68 mL.
Ensure tocilizumab and emergency equipment are available prior to the infusion and during the recovery period.
Coordinate the timing of the axicabtagene ciloleucel thaw and infusion; confirm the infusion time in advance, and adjust the start time for thaw so that the recipient will be ready.
Premedicate patients with acetaminophen and diphenhydramine approximately 1 hour prior to the infusion; avoid corticosteroids use except in the case of a life-threatening emergency.
Preparation
Match the patient's identity with the patient identifiers on the cassette; do not remove the product bag from the cassette if the patient-specific label does not match the intended recipient.
Remove the product bag from the cassette; verify that the patient information on the cassette label matches the bag label.
Put the infusion bag inside a second, sterile bag to protect against leaks and port contamination.
Thaw the infusion bag at 37 degrees Celsius (C) using either a water bath or dry thaw method; once there is no visible ice in the infusion bag, gently mix the contents of the bag to allow the clumps of cellular material to disperse.
If visible cell clumps remain, continue to 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 axicabtagene ciloleucel in new medium prior to infusion.
Storage: After thawing, the product may be stored at room temperature (20 to 25 degrees C) for up to 3 hours.
 
Intravenous (IV) Infusion
Confirm the patient's identity with the patient identifiers on the infusion bag.
Prime the tubing with normal saline prior to the infusion; do not use a leukocyte-depleting filter.
Administer as an IV infusion within 30 minutes via gravity or a peristaltic pump until the infusion bag is empty.
Gently agitate the product bag during the infusion to prevent cell clumping.
Rinse the tubing with normal saline at the same infusion rate to ensure all product contents are delivered.

Boxed Warning
Cytokine release syndrome, infection

Cytokine release syndrome (CRS) has been reported with axicabtagene ciloleucel; some cases were fatal or life-threatening. Do not administer axicabtagene ciloleucel in patients with active infection or inflammatory disorders. The use of prophylactic corticosteroids may delay the onset and decrease the duration of CRS; however, more severe neurologic toxicities or prolongation of neurologic toxicities may occur. Therefore, consider the use of prophylactic corticosteroids only after a risk versus benefit assessment taking into account individual patient comorbidities. Confirm that 2 tocilizumab doses are available at the facility site prior to the axicabtagene ciloleucel infusion. Observe patients closely for signs or symptoms of CRS at least daily for 7 days in a certified healthcare facility following the infusion and continue monitoring for at least 4 weeks after the infusion. Evaluate for and treat other causes of fever, hypoxia, and hypotension. Treat severe or life-threatening CRS with tocilizumab or tocilizumab and corticosteroids. Patients with mild symptoms (e.g., fever, nausea, fatigue, headache, myalgia, and malaise) may require symptomatic treatment only. Monitor patients with grade 2 or higher CRS (e.g., hypotension, not responsive to fluids, or hypoxia requiring supplemental oxygenation) with continuous cardiac telemetry and pulse oximetry. Consider performing an echocardiogram to assess cardiac function in patients who develop severe CRS. Intensive care supportive therapy may be required in patients who have severe or life-threatening CRS.

Driving or operating machinery, encephalopathy, mental status changes, neurotoxicity, seizures

Severe neurotoxicity (e.g., immune effector cell-associated neurotoxicity syndrome (ICANS), encephalopathy, seizures, and cerebral edema) has been reported with axicabtagene ciloleucel therapy; some cases were fatal or life-threatening. Neurologic toxicity may occur concurrently with cytokine release syndrome (CRS) or after CRS resolves. Most cases of neurotoxicity occurred within 8 weeks of the axicabtagene ciloleucel infusion. Advise patients to avoid driving or operating machinery or performing other dangerous duties for 8 weeks after the axicabtagene ciloleucel infusion due to the risk of neurologic events (e.g., mental status changes, seizures) and altered or decreased consciousness or coordination. Severe neurologic toxicities or prolongation of neurologic toxicities may occur with the use of prophylactic corticosteroids; therefore, consider the use of prophylactic corticosteroids only after a risk versus benefit assessment taking into account individual patient comorbidities. Observe patients closely for signs or symptoms of neurotoxicity at least daily for 7 days in a certified healthcare facility following the infusion and continue monitoring for at least 4 weeks after the infusion. Exclude other causes of neurologic symptoms. Administer supportive care and/or corticosteroids as indicated. Monitor patients with grade 2 or higher neurotoxicity/ICANS with continuous cardiac telemetry and pulse oximetry. Consider starting levetiracetam for seizure prophylaxis in patients who experience any grade neurotoxicity. Provide intensive care supportive therapy in patients who develop severe or life-threatening neurologic toxicities.

Used in adult patients with relapsed or refractory large B-cell lymphoma or follicular lymphoma
Cytokine release syndrome and severe neurotoxicity have been reported

Dosage And Indications
For the treatment of non-Hodgkin's lymphoma (NHL).
NOTE: Axicabtagene ciloleucel has been designated an orphan drug by the FDA for the treatment of NHL including diffuse large B-cell lymphoma, primary mediastinal B-cell lymphoma, and follicular lymphoma.
For the treatment of relapsed or refractory large B-cell lymphoma (e.g., diffuse large B-cell lymphoma (DLBCL) not otherwise specified, primary mediastinal large B-cell lymphoma, high-grade B-cell lymphoma, and DLBCL arising from follicular lymphoma) following 2 or more lines of systemic therapy. Intravenous dosage Adults

2 X 106 CAR-positive viable T-cells per kg of body weight (maximum dose of 2 X 108 CAR-positive viable T-cells) as a single IV dose. Premedicate patients with acetaminophen 650 mg PO and diphenhydramine 12.5 mg IV or PO approximately 1 hour prior to the axicabtagene ciloleucel infusion; consider prophylactic corticosteroid use following a risk versus benefit assessment. Additionally, confirm that 2 doses of tocilizumab are available for each patient prior to the infusion.[62530] The primary endpoint of investigator-assessed objective response rate was 83% in 101 evaluable patients with relapsed or refractory DLBCL (n = 77), primary mediastinal large B-cell lymphoma (n = 8), or transformed follicular lymphoma (n = 16) who received a single infusion of axicabtagene ciloleucel in a multicenter, phase 2 trial (the ZUMA-1 trial). The complete response rate was 58% and the median duration of response was 11.1 months. At a median follow-up time of 63.1 (range, 58.9 to 68.4) months, the median progression-free survival (PFS) and overall survival (OS) times were 5.9 months and 25.8 months, respectively. The estimated 5-year PFS and OS rates were 31.8% and 42.6%, respectively. Following leukapheresis and T-cell collection, all patients had lymphocyte depletion with fludarabine (30 mg/m2 IV daily for 3 doses) and cyclophosphamide (500 mg/m2 IV daily for 3 doses); each was given on the fifth, fourth, and third day prior to the axicabtagene ciloleucel infusion. Bridging chemotherapy between leukapheresis and lymphodepleting chemotherapy was not permitted. In this study, 85% of patients had stage III or IV disease, 77% of patients had disease resistant to second-line or later therapies, and 69% of patients had received at least 3 prior therapies.[63697]

For the treatment of relapsed or refractory follicular lymphoma following 2 or more lines of systemic therapy. Intravenous dosage Adults

2 X 106 CAR-positive viable T-cells per kg of body weight (maximum dose of 2 X 108 CAR-positive viable T-cells) as a single IV dose. Premedicate patients with acetaminophen 650 mg PO and diphenhydramine 12.5 mg IV or PO approximately 1 hour prior to the axicabtagene ciloleucel infusion; consider prophylactic corticosteroid use following a risk versus benefit assessment. Additionally, confirm that 2 doses of tocilizumab are available for each patient prior to the infusion. The primary endpoint of investigator-assessed objective response rate was 91% in 81 patients with relapsed or refractory follicular lymphoma who received a single infusion of axicabtagene ciloleucel in a multicenter, phase 2 trial (the ZUMA-5 trial). The complete response rate was 60%. At a median follow-up time of 14.5 months, the median time to response was 1 month (range, 0.8 to 3.1 months) and the median duration of response was not estimable (range, 0 to more than 25 months). Following leukapheresis and T-cell collection, all patients had lymphocyte depletion with fludarabine (30 mg/m2 IV daily for 3 doses) and cyclophosphamide (500 mg/m2 IV daily for 3 doses); each was given on the fifth, fourth, and third day prior to the axicabtagene ciloleucel infusion. Bridging chemotherapy between leukapheresis and lymphodepleting chemotherapy was given in 1 patient. In this study, patients (median age, 62 years; range, 34 to 79 years) had received a median of 3 prior therapies (range, 2 to 9 therapies).

For the treatment of relapsed or refractory large B-cell lymphoma that is refractory to first-line chemoimmunotherapy or that relapses within 12 months of first-line chemoimmunotherapy. Intravenous dosage Adults

2 X 106 CAR-positive viable T-cells per kg of body weight (maximum dose of 2 X 108 CAR-positive viable T-cells) as a single IV dose. Premedicate patients with acetaminophen 650 mg PO and diphenhydramine 12.5 mg IV or PO approximately 1 hour prior to the axicabtagene ciloleucel infusion; consider prophylactic corticosteroid use following a risk versus benefit assessment. Additionally, confirm that 2 doses of tocilizumab are available for each patient prior to the infusion. The median event-free survival (primary endpoint; 8.3 months vs. 2 months; hazard ratio (HR) = 0.4; 95% CI, 0.31 to 0.51; p less than 0.001) and progression-free survival (14.7 months vs. 3.7 months; HR = 0.49; 95% CI, 0.37 to 0.65) times were significantly improved in transplant-eligible patients with relapsed or refractory LBCL who received second-line therapy with axicabtagene ciloleucel compared with 2 or 3 cycles of investigator-selected standard care in a randomized, phase 3 (ZUMA-7) trial (n = 359; median follow-up time, 24.9 months). At a median follow-up of 47.2 (range, 39.8 to 60) months, the median overall survival time was not reached in the axicabtagene ciloleucel arm and 31.1 months in the standard care arm (HR = 0.73; 95% CI, 0.54 to 0.98). Of note, 102 patients (57%) who had disease progression or lack of response in the standard care group received subsequent cellular immunotherapy outside the protocol; 79 out of 102 of these patients (77.5%) received subsequent axicabtagene ciloleucel. Following leukapheresis and T-cell collection, patient who received axicabtagene ciloleucel had lymphocyte depletion with fludarabine (30 mg/m2 IV daily for 3 doses) and cyclophosphamide (500 mg/m2 IV daily for 3 doses); each was given on the fifth, fourth, and third day prior to the axicabtagene ciloleucel infusion. Optional bridging chemotherapy between leukapheresis and lymphodepleting chemotherapy was limited to glucocorticoids only. In this trial, patients (median age, 59 years; range, 21 to 81 years) had LBCL that was refractory to or had relapsed no more than 12 months after first-line chemoimmunotherapy (including an anti-CD20 monoclonal antibody and anthracycline-containing regimen). Investigator-selected standard care consisted of protocol-defined, platinum-based, chemoimmunotherapy.

Drug Interactions

Cholera Vaccine: (Moderate) Patients receiving immunosuppressant medications may have a diminished response to the live cholera vaccine. When feasible, administer indicated vaccines prior to initiating immunosuppressant medications. Counsel patients receiving immunosuppressant medications about the possibility of a diminished vaccine response and to continue to follow precautions to avoid exposure to cholera bacteria after receiving the vaccine.
Live Vaccines: (Contraindicated) Avoid administration of live virus vaccines in the six weeks prior to the start of lymphodepleting chemotherapy, during axicabtagene ciloleucel therapy, and prior to immune recovery following treatment with axicabtagene ciloleucel. Patients with altered immunocompetence, including those receiving or those that have recently received immunosuppressive drug therapy, may be at increased risk for an adverse reaction because of uninhibited growth of the attenuated live virus. Additionally, vaccines may be less effective if administered during a period of altered immunocompetence.
SARS-CoV-2 (COVID-19) vaccines: (Moderate) Patients receiving immunosuppressant medications may have a diminished response to the SARS-CoV-2 virus vaccine. When feasible, administer indicated vaccines prior to initiating immunosuppressant medications. Counsel patients receiving immunosuppressant medications about the possibility of a diminished vaccine response and to continue to follow precautions to avoid exposure to SARS-CoV-2 virus after receiving the vaccine.

Mechanism Of Action

Axicabtagene ciloleucel is a chimeric antigen receptor (CAR) T-cell therapy that works by redirecting T-cells to target the CD19 antigen on B-cells in patients with hematologic malignancies. The domains, CD28 and CD3-zeta, activate downstream signaling cascades that lead to T-cell activation, proliferation, acquisition of effector functions, and secretion of inflammatory cytokines and chemokines. The binding of CAR to CD19 activates axicabtagene ciloleucel and promotes cell expansion and differentiation and triggers the lysis of CD19-positive cells.
This immunotherapy involves removing, genetically modifying, and then re-infusing a patient’s own T-cells. During the manufacturing process, the cells are genetically modified using retroviral transduction to express a CAR comprised of a murine anti-CD19 single chain variable fragment linked to CD28 and CD3-zeta co-stimulatory domains.
To produce CAR T-cell therapy, T-cells are collected from the blood by leukapheresis; enriched; activated with anti-CD3 antibody in the presence of IL-2; transduced with the replication incompetent retroviral vector containing the anti-CD19 CAR transgene; expanded to large numbers in a cell culture; and then washed, formulated into a suspension, and cryopreserved.

Pharmacokinetics

Axicabtagene ciloleucel is administered intravenously. The number of anti-CD19 chimeric antigen receptor (CAR) T-cells in blood correlated with objective response in evaluable patients with relapsed or refractory aggressive B-cell non-Hodgkin's lymphoma who received axicabtagene ciloleucel (n = 96) in a nonrandomized trial. The time to peak anti-CD19 CAR T-cell levels occurred within 7 to 14 days following the axicabtagene ciloleucel infusion.
Pharmacodynamics: Peak levels of cytokines and chemokines (e.g., IL-6, IL-8, IL-10, IL-15, TNF-alpha, IFN-gamma, and sIL2R-alpha) were observed within 14 days of the axicabtagene ciloleucel infusion; these levels typically returned to baseline within 28 days.

Intravenous Route

In patients with large B-cell lymphoma (LBL), the median anti-CD19 chimeric antigen receptor (CAR) T-cell Cmax and AUC(0-28 days) values were 205% (43.6 vs. 21.2 cells/microliter (microL)) and 251% (557.1 vs. 222 days X cells/microL) higher, respectively, in 73 patients who achieved an objective response compared (responders) with 23 patients who were nonresponders in a nonrandomized trial. Additionally, patients with LBL had median anti-CD19 CAR T cell Cmax and AUC(0-28 days) values that were 275% (28.9 vs. 10.5 cells/microL) and 418% (292.9 vs. 70.1 days X cells/microL) higher, respectively, in 142 responders compared with 20 nonresponders in another clinical trial. In patients with follicular lymphoma, the median anti-CD19 CAR T-cell Cmax level was 40.1 cells/microL in 74 patients who achieved an objective response and 46 cells/microL in 7 patients who were nonresponders in a nonrandomized trial; the median anti-CD19 CAR T-cell AUC(0-28 days) values were 465.8 and 404.5 days X cells/microL, respectively.

Pregnancy And Lactation
Pregnancy

Pregnancy should be avoided by females of reproductive potential during axicabtagene ciloleucel treatment; pregnancy after axicabtagene ciloleucel administration should be discussed with the treating physician. There are no available data with axicabtagene ciloleucel use in pregnant women; animal reproductive and developmental toxicity studies have not been conducted. It is not known if axicabtagene ciloleucel has the potential to be transferred to the fetus. However, based on its mechanism of action, fetal toxicity including B-cell lymphocytopenia may occur if the transduced cells cross the placenta.

It is not known if axicabtagene ciloleucel is secreted in human milk or if it has effects on the breast-fed infant or on milk production. Consider the developmental and health benefits of breast-feeding along with the mother’s clinical need for axicabtagene ciloleucel and any potential adverse effects on the breast-fed infant from axicabtagene ciloleucel or from the underlying maternal condition.
