Warnings/Precautions
Cytokine Release Syndrome
CRS, including fatal or life-threatening reactions, occurred following treatment with axicabtagene ciloleucel.(1) CRS occurred in 90% (379/422) of patients with non-Hodgkin lymphoma (NHL) receiving axicabtagene ciloleucel, including ≥ Grade 3 (Lee grading system1) CRS in 9%.(1) CRS occurred in 93% (256/276) of patients with large B-cell lymphoma (LBCL), including ≥ Grade 3 CRS in 9%.(1) Among patients with LBCL who died after receiving axicabtagene ciloleucel, four had ongoing CRS events at the time of death.(1) For patients with LBCL in the ZUMA-1 study, the median time to onset of CRS was 2 days following infusion (range: 1 to12 days) and the median duration of CRS was 7 days (range: 2 to 58 days).(1) For patients with LBCL in the ZUMA-7 study, the median time to onset of CRS was 3 days following infusion (range: 1 to 10 days) and the median duration was 7 days (range: 2 to 43 days).(1)
CRS occurred in 84% (123/146) of patients with indolent non-Hodgkin lymphoma (iNHL) in the ZUMA-5 study, including ≥ Grade 3 CRS in 8%.(1) Among patients with iNHL who died after receiving axicabtagene ciloleucel, one patient had an ongoing CRS event at the time of death.(1) The median time to onset of CRS was 4 days (range: 1 to 20 days) and the median duration was 6 days (range: 1 to 27 days) for patients with iNHL.(1)
Key manifestations of CRS (≥ 10%) in all patients combined included fever (85%), hypotension (40%), tachycardia (32%), chills (22%), hypoxia (20%), headache (15%), and fatigue (12%).(1) Serious events that may be associated with CRS include cardiac arrhythmias (including atrial fibrillation and ventricular tachycardia), renal insufficiency, cardiac failure, respiratory failure, cardiac arrest, capillary leak syndrome, multi-organ failure, and hemophagocytic lymphohistiocytosis/macrophage activation syndrome (HLH/MAS).(1)
The impact of tocilizumab and/or corticosteroids on the incidence and severity of CRS was assessed in two subsequent cohorts of LBCL patients in ZUMA-1.(1) Among patients who received tocilizumab and/or corticosteroids for ongoing Grade 1 events, CRS occurred in 93% (38/41), including 2% (1/41) with Grade 3 CRS; no patients experienced a Grade 4 or 5 event.(1) The median time to onset of CRS was 2 days (range: 1 to 8 days) and the median duration of CRS was 7 days (range: 2 to 16 days).(1)
Prophylactic treatment with corticosteroids was administered to a cohort of 39 patients for 3 days beginning on the day of infusion of axicabtagene ciloleucel.(1) Thirty-one of the 39 patients (79%) developed CRS at which point the patients were managed with tocilizumab and/or therapeutic doses of corticosteroids with no patients developing Grade 3 or higher CRS.(1) The median time to onset of CRS was 5 days (range: 1 to 15 days) and the median duration of CRS was 4 days (range: 1 to 10 days).(1) Although there is no known mechanistic explanation, consider the risk and benefits of prophylactic corticosteroids in the context of pre-existing comorbidities for the individual patient and the potential for the risk of Grade 4 and prolonged neurologic toxicities.(1)
Ensure that 2 doses of tocilizumab are available prior to infusion of axicabtagene ciloleucel.(1) Monitor patients at least daily for 7 days at the certified healthcare facility following infusion for signs and symptoms of CRS.(1) Monitor patients for signs or symptoms of CRS for 4 weeks after infusion.(1) Counsel patients to seek immediate medical attention should signs or symptoms of CRS occur at any time.(1) At the first sign of CRS, institute treatment with supportive care, tocilizumab, or tocilizumab and corticosteroids as indicated.(1)
Neurologic Toxicities
Neurologic toxicities (including ICANS) that were fatal or life-threatening occurred following treatment with axicabtagene ciloleucel.(1) Neurologic toxicities occurred in 78% (330/422) of patients with NHL receiving axicabtagene ciloleucel, including ≥ Grade 3 cases in 25%.(1)
Neurologic toxicities occurred in 87% (94/108) of patients with LBCL in ZUMA-1, including ≥ Grade 3 cases in 31% and in 74% (124/168) of patients in ZUMA-7 including ≥ Grade 3 cases in 25%.(1) The median time to onset was 4 days (range: 1 to 43 days) and the median duration was 17 days in patients with LBCL in ZUMA-1.(1) The median time to onset for neurologic toxicity was 5 days (range:1 to 133 days) and median duration was 15 days in patients with LBCL in ZUMA-7.(1) Neurologic toxicities occurred in 77% (112/146) of patients with iNHL, including ≥ Grade 3 in 21%.(1) The median time to onset was 6 days (range: 1 to 79 days) and the median duration was 16 days.(1) Ninety-eight percent of all neurologic toxicities in patients with LBCL and 99% of all neurologic toxicities in patients with iNHL occurred within the first 8 weeks of axicabtagene ciloleucel infusion.(1) Neurologic toxicities occurred within the first 7 days of axicabtagene ciloleucel infusion in 87% of affected patients with LBCL and 74% of affected patients with iNHL.(1)
The most common neurologic toxicities (≥ 10%) in all patients combined included encephalopathy (50%), headache (43%), tremor (29%), dizziness (21%), aphasia (17%), delirium (15%), and insomnia (10%).(1) Prolonged encephalopathy lasting up to 173 days was noted.(1) Serious events including aphasia, leukoencephalopathy, dysarthria, lethargy, and seizures occurred with axicabtagene ciloleucel.(1) Fatal and serious cases of cerebral edema and encephalopathy, including late-onset encephalopathy, have occurred in patients treated with axicabtagene ciloleucel.(1)
The impact of tocilizumab and/or corticosteroids on the incidence and severity of neurologic toxicities was assessed in two subsequent cohorts of LBCL patients in ZUMA-1.(1) Among patients who received corticosteroids at the onset of Grade 1 toxicities neurologic toxicities occurred in 78% (32/41) and 20% (8/41) had Grade 3 neurologic toxicities; no patients experienced a Grade 4 or 5 event.(1) The median time to onset of neurologic toxicities was 6 days (range: 1 to 93 days) with a median duration of 8 days (range: 1 to 144 days).(1) Prophylactic treatment with corticosteroids was administered to a cohort of 39 patients for 3 days beginning on the day of infusion of axicabtagene ciloleucel.(1) Of these 39 patients, 85% (33/39) developed neurologic toxicities; 8% (3/39) developed Grade 3 and 5% (2/39) developed Grade 4 neurologic toxicities.(1) The median time to onset of neurological toxicities was 6 days (range: 1 to 274 days) with a median duration of 12 days (range: 1 to 107 days).(1) Prophylactic corticosteroids for management of CRS and neurologic toxicities may result in higher grade of neurologic toxicities or prolongation of neurologic toxicities, delay the onset and decrease the duration of CRS.(1)
Monitor patients at least daily for 7 days at the certified healthcare facility following infusion for signs and symptoms of neurologic toxicities.(1) Monitor patients for signs or symptoms of neurologic toxicities for 4 weeks after infusion and treat promptly.(1)
REMS Program
Because of the risk of CRS and neurologic toxicities, axicabtagene ciloleucel is available only through a restricted program under a Risk Evaluation and Mitigation Strategy (REMS) called the YESCARTA and TECARTUS REMS Program.(1) The required components of the REMS Program are: (1)
Healthcare facilities that dispense and administer axicabtagene ciloleucel must be enrolled and comply with the REMS requirements.(1) Certified healthcare facilities must have on-site, immediate access to tocilizumab, and ensure that a minimum of 2 doses of tocilizumab are available for each patient for infusion within 2 hours after axicabtagene ciloleucel infusion, if needed for treatment of CRS.(1)
Certified healthcare facilities must ensure that healthcare providers who prescribe, dispense, or administer axicabtagene ciloleucel are trained about the management of CRS and neurologic toxicities.(1)
Further information is available at www.YescartaTecartusREMS.com or 1-844-454-KITE (5483).(1)
Hypersensitivity Reactions
Allergic reactions may occur with the infusion of axicabtagene ciloleucel.(1) Serious hypersensitivity reactions, including anaphylaxis, may be due to dimethyl sulfoxide (DMSO) or residual gentamicin in axicabtagene ciloleucel.(1)
Serious Infections
Severe or life-threatening infections occurred in patients after axicabtagene ciloleucel infusion.(1) Infections (all grades) occurred in 45% of patients with NHL.(1) Grade 3 or higher infections occurred in 17% of patients, including Grade 3 or higher infections with an unspecified pathogen in 12%, bacterial infections in 5%, viral infections in 3%, and fungal infections in 1%.(1) Axicabtagene ciloleucel should not be administered to patients with clinically significant active systemic infections.(1) Monitor patients for signs and symptoms of infection before and after axicabtagene ciloleucel infusion and treat appropriately.(1) Administer prophylactic antimicrobials according to local guidelines.(1)
Febrile neutropenia was observed in 36% of patients with NHL after axicabtagene ciloleucel infusion and may be concurrent with CRS.(1) In the event of febrile neutropenia, evaluate for infection and manage with broad-spectrum antibiotics, fluids, and other supportive care as medically indicated.(1)
In immunosuppressed patients, including those who have received axicabtagene ciloleucel, life-threatening and fatal opportunistic infections including disseminated fungal infections (e.g., candida sepsis and aspergillus infections) and viral reactivation (e.g., human herpes virus-6 [HHV-6] encephalitis and JC virus progressive multifocal leukoencephalopathy [PML]) have been reported.(1) The possibility of HHV-6 encephalitis and PML should be considered in immunosuppressed patients with neurologic events and appropriate diagnostic evaluations should be performed.(1)
Hepatitis B Virus Reactivation
Hepatitis B virus (HBV) reactivation, in some cases resulting in fulminant hepatitis, hepatic failure, and death, has occurred in patients treated with drugs directed against B cells, including axicabtagene ciloleucel.(1) Perform screening for HBV, HCV, and HIV, and manage in accordance with clinical guidelines before collection of cells for manufacturing.(1)
Prolonged Cytopenias
Patients may exhibit cytopenias for several weeks following lymphodepleting chemotherapy and axicabtagene ciloleucel infusion.(1) Grade 3 or higher cytopenias not resolved by Day 30 following axicabtagene ciloleucel infusion occurred in 39% of all patients with NHL and included neutropenia (33%), thrombocytopenia (13%), and anemia (8%).(1) Monitor blood counts after axicabtagene ciloleucel infusion.(1)
Hypogammaglobulinemia
B-cell aplasia and hypogammaglobulinemia can occur in patients receiving treatment with axicabtagene ciloleucel.(1) Hypogammaglobulinemia was reported as an adverse reaction in 14% of all patients with NHL.(1) Monitor immunoglobulin levels after treatment with axicabtagene ciloleucel and manage using infection precautions, antibiotic prophylaxis, and immunoglobulin replacement.(1)
The safety of immunization with live viral vaccines during or following axicabtagene ciloleucel treatment has not been studied.(1) Vaccination with live virus vaccines is not recommended for at least 6 weeks prior to the start of lymphodepleting chemotherapy, during axicabtagene ciloleucel treatment, and until immune recovery following treatment with axicabtagene ciloleucel.(1)
Secondary Malignancies
Patients treated with axicabtagene ciloleucel may develop secondary malignancies.(1) Monitor life-long for secondary malignancies.(1) In the event that a secondary malignancy occurs, contact Kite at 1-844-454-KITE (5483) to obtain instructions on patient samples to collect for testing.(1)
Effects on Ability to Drive and Use Machines
Due to the potential for neurologic events, including altered mental status or seizures, patients receiving axicabtagene ciloleucel are at risk for altered or decreased consciousness or coordination in the 8 weeks following axicabtagene ciloleucel infusion.(1) Advise patients to refrain from driving and engaging in hazardous occupations or activities, such as operating heavy or potentially dangerous machinery, during this initial period.(1)
Specific Populations
Pregnancy
There are no available data with axicabtagene ciloleucel use in pregnant women.(1) No animal reproductive and developmental toxicity studies have been conducted with axicabtagene ciloleucel to assess whether it can cause fetal harm when administered to a pregnant woman.(1) It is not known if axicabtagene ciloleucel has the potential to be transferred to the fetus.(1) Based on the mechanism of action, if the transduced cells cross the placenta, they may cause fetal toxicity, including B-cell lymphocytopenia.(1) Therefore, axicabtagene ciloleucel is not recommended for women who are pregnant, and pregnancy after axicabtagene ciloleucel infusion should be discussed with the treating physician.(1)
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.(1)
Lactation
There is no information regarding the presence of axicabtagene ciloleucel in human milk, the effect on the breastfed infant, and the effects on milk production.(1) The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for axicabtagene ciloleucel and any potential adverse effects on the breastfed infant from axicabtagene ciloleucel or from the underlying maternal condition.(1)
Females and Males of Reproductive Potential
Pregnancy status of females with reproductive potential should be verified.(1) Sexually active females of reproductive potential should have a pregnancy test prior to starting treatment with axicabtagene ciloleucel.(1)
See the prescribing information for fludarabine and cyclophosphamide for information on the need for effective contraception in patients who receive the lymphodepleting chemotherapy.(1)
There are insufficient exposure data to provide a recommendation concerning duration of contraception following treatment with axicabtagene ciloleucel.(1)
There are no data on the effect of axicabtagene ciloleucel on fertility.(1)
Pediatric Use
The safety and efficacy of axicabtagene ciloleucel have not been established in pediatric patients.(1)
Geriatric Use
Of the 422 patients with NHL who received axicabtagene ciloleucel in clinical trials, 127 patients (30%) were 65 years of age and older.(1) No clinically important differences in safety or effectiveness were observed between patients 65 years of age and older and younger patients.(1)
Common Adverse Effects
The most common adverse reactions (incidence ≥ 30%), excluding laboratory abnormalities, in patients with non-Hodgkin lymphoma are CRS, fever, hypotension, encephalopathy, fatigue, tachycardia, headache, nausea, febrile neutropenia, diarrhea, musculoskeletal pain, infections with pathogen unspecified, chills, and decreased appetite.(1)
The most common Grade 3-4 laboratory abnormalities (≥ 30%) are leukopenia, lymphopenia, neutropenia, anemia, thrombocytopenia, and hypophosphatemia.(1)
