Pediatric and Young Adult Relapsed or Refractory B-cell Acute Lymphoblastic Leukemia
Adult Relapsed or Refractory Diffuse Large B-cell Lymphoma and r/r Follicular Lymphoma
• Lymphodepleting chemotherapy: Fludarabine (25 mg/m2 intravenously daily for 3 days) and cyclophosphamide (250 mg/m2 intravenously daily for 3 days starting with the first dose of fludarabine).
• Alternate lymphodepleting chemotherapy: bendamustine 90 mg/m2 intravenously daily for 2 days if a patient experienced a previous Grade 4 hemorrhagic cystitis with cyclophosphamide or demonstrates resistance to a previous cyclophosphamide containing regimen.
• Infuse KYMRIAH 2 to 11 days (r/r DLBCL) or 2 to 6 days (r/r FL) after completion of the lymphodepleting chemotherapy.
• Lymphodepleting chemotherapy may be omitted if a patient is experiencing significant cytopenia, e.g., white blood cell (WBC) count is less than 1 x 109/L within 1 week prior to KYMRIAH infusion.
Preparation of KYMRIAH for Infusion and Administration
Delay the infusion of KYMRIAH if a patient has unresolved serious adverse reactions (including pulmonary reactions, cardiac reactions, or hypotension) from preceding chemotherapies, active uncontrolled infection, active graft versus host disease (GVHD), or worsening of leukemia burden following lymphodepleting chemotherapy [see Warnings and Precautions (5.1)].
A KYMRIAH dose may be contained in one to three cryopreserved patient specific infusion bag(s). Verify the number of bags received for the dose of KYMRIAH with the Certificate of Conformance (CoC) and Certificate of Analysis (CoA). Coordinate the timing of thaw of KYMRIAH and infusion in the following manner. Confirm the infusion time in advance, and adjust the start time for thaw so that KYMRIAH is available for infusion when the recipient is ready. If more than one bag has been received for the treatment dose, thaw 1 bag at a time. Wait to thaw/infuse the next bag until it is determined that the previous bag is safely administered.
Preparation of KYMRIAH for Infusion
1. Confirm tocilizumab and emergency equipment are available prior to infusion and during the recovery period.
2. Premedicate patient with acetaminophen and diphenhydramine or another H1-antihistamine approximately 30 to 60 minutes prior to KYMRIAH infusion. Avoid prophylactic use of systemic corticosteroids, as it may interfere with the activity of KYMRIAH.
3. Confirm patient identity: Prior to KYMRIAH preparation, match the patient's identity with the patient identifiers on each KYMRIAH infusion bag(s). KYMRIAH is for autologous use only. Employ universal precautions to avoid potential transmission of infectious diseases when handling the product.
Note: The patient identifier number may be preceded by the letters DIN or Aph ID.
Figure 1. KYMRIAH Infusion Bag
4. Inspect the infusion bag(s) for any breaks or cracks prior to thawing. If a bag is compromised, do not infuse the contents. Call Novartis at 1-844-4KYMRIAH.
5. Place the infusion bag inside a second, sterile bag in case of a leak and to protect ports from contamination.
6. Thaw each infusion bag one at a time at 37°C using either a water bath or dry thaw method until there is no visible ice in the infusion bag. Remove bag from thawing device immediately; do not store product bag at 37°C. Once the infusion bag has been thawed and is at room temperature (20°C to 25°C), it should be infused within 30 minutes. Do not wash, spin down, and/or resuspend KYMRIAH in new media prior to infusion.
7. Inspect the contents of the thawed infusion bag for any 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 KYMRIAH if clumps are not dispersed, the infusion bag is damaged or leaking, or otherwise appears to be compromised. Call Novartis at 1-844-4KYMRIAH.
Administration of KYMRIAH
8. Confirm the patient’s identity with the patient identifiers on the infusion bag.
9. Administer KYMRIAH as an intravenous infusion at 10 mL to 20 mL per minute, adjusted as appropriate for smaller children and smaller volumes. The volume in the infusion bag ranges from 10 mL to 50 mL. Do NOT use a leukocyte-depleting filter. If more than one bag is being infused for the treatment dose, wait to thaw/infuse the next bag until it is determined that the previous bag is safely administered.
- Prime the tubing prior to infusion with sodium chloride 9 mg/mL (0.9%) solution for injection.
- Infuse all contents of the infusion bag.
- Rinse the infusion bag with 10 mL to 30 mL sodium chloride 9 mg/mL (0.9%) solution for injection while maintaining a closed tubing system to assure as many cells as possible are infused into the patient.
- Cells from all the bag(s) must be infused to complete a single dose.
KYMRIAH contains human cells genetically modified with a lentivirus. Follow local biosafety guidelines applicable for handling and disposal of such products.
Monitoring
- Monitor patients daily during the first week following KYMRIAH infusion for signs and symptoms of CRS and neurologic toxicities [see Warnings and Precautions (5.1, 5.2)].
- Instruct patients to remain within proximity of a healthcare facility for at least 2 weeks following infusion.
- Advise patients to avoid driving for at least 2 weeks following infusion.
Cytokine Release Syndrome

If not improving, consider methylprednisolone 1,000 mg intravenously two to three times a day or alternate therapyd. Continue corticosteroids until improvement to Grade 1, and then taper as clinically appropriate. |
Neurologic Toxicities
Patients should be monitored for neurologic toxicities, including ICANS, following KYMRIAH infusion, particularly during and after resolution of CRS. Identify neurologic toxicities based on clinical presentation. Evaluate for and treat other causes of neurological symptoms. Consider non-sedating seizure prophylaxis (e.g., levetiracetam) for patients at higher risk of seizure, such as those with seizure history, CNS disease, concerning EEG findings, or neoplastic brain lesions. If neurologic toxicity is suspected, manage according to the recommendations in Table 2. Alternative neurologic toxicities management strategies may be implemented based on appropriate institutional, academic, or consensus guidelines.

Pediatric and Young Adult r/r B-cell ALL (up to 25 years of age): A single dose of KYMRIAH contains 0.2 to 5.0 x 106 CAR-positive viable T cells per kg of body weight for patients 50 kg and below or 0.1 to 2.5 x 108 CAR-positive viable T cells for patients above 50 kg, suspended in one to three patient-specific infusion bag(s) [see How Supplied/Storage and Handling (16)].
Adult r/r DLBCL and r/r FL: A single dose of KYMRIAH contains 0.6 to 6.0 x 108 CAR-positive viable T cells, which may be suspended in one to three patient-specific infusion bag(s) [see How Supplied/Storage and Handling (16)].
See the CoA for actual cell count. The volume in the infusion bag ranges from 10 mL to 50 mL.
None.
Cytokine release syndrome (CRS), including fatal or life-threatening reactions, occurred following treatment with KYMRIAH. CRS occurred in 61 (77%) of the 79 pediatric and young adult patients with r/r ALL receiving KYMRIAH, including ≥ Grade 3 CRS (Penn grading system1) occurring in 48% of patients. The median times to onset and resolution of CRS were 3 days (range, 1 to 22; 1 patient with onset after Day 10) and 8 days (range, 1 to 36), respectively. Of the 61 patients with CRS, 31 (51%) received tocilizumab. Ten (16%) patients received two doses of tocilizumab and 3 (5%) patients received three doses of tocilizumab; 17 (28%) patients received addition of corticosteroids (e.g., methylprednisolone).
CRS occurred in 85 (74%) of the 115 adult patients with r/r DLBCL receiving KYMRIAH, including ≥ Grade 3 CRS (Penn grading system1) occurring in 23% of patients. The median times to onset and resolution of CRS were 3 days (range, 1 to 51; 1 patient with onset after Day 10) and 7 days (range, 2 to 30), respectively. Of the 85 patients with CRS, 19 (22%) received systemic tocilizumab or corticosteroids. Seven (8%) patients received a single dose of tocilizumab and 11 (13%) patients received two doses of tocilizumab; 11 (13%) patients received corticosteroids in addition to tocilizumab. One patient received corticosteroids for CRS without concomitant tocilizumab, and two patients received corticosteroids for persistent neurotoxicity after resolution of CRS.
CRS occurred in 51 (53%) of the 97 adult patients with r/r FL receiving KYMRIAH; all were Grade 1 or 2 CRS (Lee grading system2). The median times to onset and resolution of CRS were 4 days (range, 1 to 14) and 4 days (range, 1 to 13), respectively. Of the 51 patients with CRS, 15 (29%) received systemic anticytokine treatment with tocilizumab. Three (6%) patients required 3 dosages of tocilizumab, 4 (8%) patients required 2 dosages and 8 (16%) patients required single dose of tocilizumab. Two (4%) patients received corticosteroids in addition to tocilizumab.
Five deaths occurred within 30 days of KYMRIAH infusion. One patient with r/r ALL died with CRS and progressive leukemia, and one patient had resolving CRS with abdominal compartment syndrome, coagulopathy, and renal failure when an intracranial hemorrhage occurred. Of the 3 r/r DLBCL patients who died within 30 days of infusion, all had CRS in the setting of stable to progressive underlying disease, one of whom developed bowel necrosis.
Among patients with CRS, key manifestations include fever (93% in r/r ALL; 85% in r/r DLBCL; 92% in r/r FL), hypotension (69% in r/r ALL; 45% in r/r DLBCL; 40% in r/r FL), hypoxia (57% in r/r ALL; 35% in r/r DLBCL; 19% in r/r FL), and tachycardia (26% in r/r ALL; 13% in r/r DLBCL; 2% in r/r FL). CRS may be associated with hepatic, renal, and cardiac dysfunction, and coagulopathy.
Delay the infusion of KYMRIAH after lymphodepleting chemotherapy if the patient has unresolved serious adverse reactions from preceding chemotherapies (including pulmonary toxicity, cardiac toxicity, or hypotension), active uncontrolled infection, active graft versus host disease (GVHD), or worsening of leukemia burden [see Dosage and Administration (2.2)].
Risk factors for severe CRS in the pediatric and young adult r/r B-cell ALL population are high pre-infusion tumor burden (greater than 50% blasts in bone marrow), uncontrolled or accelerating tumor burden following lymphodepleting chemotherapy, active infections, and/or inflammatory processes.
Confirm that a minimum of two doses of tocilizumab are available on site prior to infusion of KYMRIAH.
Monitor patients daily during the first week following KYMRIAH infusion for signs and symptoms of CRS. Monitor patients for signs or symptoms of CRS for at least 2 weeks after treatment with KYMRIAH. At the first sign of CRS, immediately evaluate patient for hospitalization and institute treatment with supportive care, tocilizumab and/or corticosteroids as indicated [see Dosage and Administration (2.2, 2.3)].
Counsel patients to seek immediate medical attention should signs or symptoms of CRS occur at any time [see Patient Counseling Information (17)].
Neurological toxicities, including severe or life-threatening reactions, occurred following treatment with KYMRIAH. Neurologic toxicities occurred in 56 (71%) of the 79 patients with r/r ALL, including ≥ Grade 3 in 22%. The median times to the first event and duration were 6 days from infusion (range, 1 to 301) and 7 days, respectively.
Neurologic toxicities occurred in 69 (60%) of the 115 patients with r/r DLBCL, including ≥ Grade 3 in 19%. The median times to the first event and duration were 5 days (range, 1 to 368) and 17 days, respectively.
Neurologic toxicities occurred in 42 (43%) of the 97 patients with r/r FL, including ≥ Grade 3 in 6%. The median times to the first event and duration were 8 days (range, 1 to 345) and 5 days, respectively.
Among patients who had a neurological toxicity, 84% occurred within 8 weeks following KYMRIAH infusion. Resolution occurred within 3 weeks in 71% of patients with r/r ALL, 50% of patients with r/r DLBCL, and 74% of patients with r/r FL. Encephalopathy lasting up to 70 days was noted.
The onset of neurological toxicity can be concurrent with CRS, following resolution of CRS or in the absence of CRS.
The most common neurological toxicities observed with KYMRIAH include headache (35% in r/r ALL; 21% in r/r DLBCL; 25% in r/r FL), encephalopathy (30% in r/r ALL; 16% in r/r DLBCL; 3% in r/r FL), delirium (19% in r/r ALL; 5% in r/r DLBCL; 1% in r/r FL), anxiety (16% in r/r ALL; 10% in r/r DLBCL; 2% in r/r FL), sleep disorders (11% in r/r ALL; 10% in r/r DLBCL; 6% in r/r FL), dizziness (5% in r/r ALL; 12% in r/r DLBCL; 8% in r/r FL), tremor (8% in r/r ALL; 6% in r/r DLBCL; 3% in r/r FL), and peripheral neuropathy (4% in r/r ALL; 12% in r/r DLBCL; 7% in r/r FL). Other manifestations included seizures and aphasia.
Monitor patients daily during the first week following KYMRIAH infusion for signs and symptoms of neurologic toxicities. Rule out other causes of neurological symptoms. Monitor patients for signs or symptoms of neurologic toxicities for at least 2 weeks after infusion and treat promptly. Neurologic toxicity should be managed with supportive care and/or corticosteroids as needed [see Dosage and Administration (2.3)]. Advise patients to avoid driving for at least 2 weeks following infusion.
Counsel patients to seek immediate medical attention should signs or symptoms of neurologic toxicity occur at any time [see Patient Counseling Information (17)].
Hemophagocytic Lymphohistiocytosis (HLH)/Macrophage Activation Syndrome (MAS), which can be life-threatening or fatal, has occurred following treatment with KYMRIAH. HLH was reported in 6% (5/79) of patients with r/r ALL (time to onset ranged from 3 to 18 days) and 2% (2/115) of patients with r/r DLBCL (times to onset were Day 7 and Day 10); all HLH events occurred during ongoing CRS and resolved. One patient (1%) with r/r FL developed HLH > 1 year after receiving KYMRIAH with a fatal outcome. The patient did not have CRS during or immediately preceding HLH. Treatment of HLH should be administered as per institutional standards.
Hypersensitivity reactions may occur with infusion of KYMRIAH. Serious hypersensitivity reactions, including anaphylaxis, may be due to the dimethyl sulfoxide (DMSO) or dextran 40 in KYMRIAH. Observe patients for hypersensitivity reactions during and after the infusion.
Infections, including life-threatening or fatal infections, occurred following treatment with KYMRIAH. Infections occurred in 57 (72%) of the 79 patients with r/r ALL; 38 patients (48%) experienced ≥ Grade 3 infections, including fatal infections in 2 patients (3%).
Infections occurred in 67 (58%) of the 115 patients with r/r DLBCL; 38 patients (33%) experienced ≥ Grade 3 infections, including fatal infection in 1 patient (1%).
Infections occurred in 50 (52%) of the 97 patients with r/r FL; 20 patients (21%) experienced ≥ Grade 3 infections, including fatal infection in 1 patient (1%).
Prior to KYMRIAH infusion, infection prophylaxis should follow local guidelines. Patients with active uncontrolled infection should not start KYMRIAH treatment until the infection is resolved. Monitor patients for signs and symptoms of infection after treatment with KYMRIAH and treat appropriately [see Dosage and Administration (2.2)].
Febrile neutropenia (≥ Grade 3) was also observed in 34% of patients with r/r ALL, 17% of patients with r/r DLBCL, and 13% of patients with r/r FL after KYMRIAH infusion and may be concurrent with CRS. In the event of febrile neutropenia, evaluate for infection and manage with broad spectrum antibiotics, fluids and other supportive care as medically indicated.
In immunosuppressed patients, opportunistic fatal infections of the central nervous system including progressive multifocal leukoencephalopathy due to John Cunningham virus reactivation have occurred after KYMRIAH administration [see Clinical Trial Experience (6.1) and Postmarketing Experience (6.2)]. Perform appropriate diagnostic evaluations in patients with neurological adverse events.
Viral Reactivation
Hepatitis B virus (HBV) reactivation, in some cases resulting in fulminant hepatitis, hepatic failure and death, can occur in patients treated with drugs directed against B cells.
There is no experience with manufacturing KYMRIAH for patients with a positive test for HIV or with active HBV or active HCV. Perform screening for HBV, HCV, and HIV in accordance with clinical guidelines before collection of cells for manufacturing.
Patients may exhibit cytopenias for several weeks following lymphodepleting chemotherapy and KYMRIAH infusion.
In Study 1, ≥ Grade 3 cytopenias not resolved by Day 28 following KYMRIAH treatment included neutropenia (40%), and thrombocytopenia (27%) among 52 responding patients. At 56 days following KYMRIAH, 17% and 12% of responding patients had ≥ Grade 3 neutropenia or thrombocytopenia, respectively.
In Study 2, ≥ Grade 3 cytopenias not resolved by Day 28 following KYMRIAH treatment included thrombocytopenia (39%) and neutropenia (25%) among 115 treated patients.
In Study 3, ≥ Grade 3 cytopenias not resolved by Day 28 following KYMRIAH treatment included thrombocytopenia (17%) and neutropenia (16%) among 97 treated patients.
Prolonged neutropenia has been associated with increased risk of infection. Myeloid growth factors, particularly GM-CSF, are not recommended during the first 3 weeks after KYMRIAH infusion or until CRS has resolved.
Hypogammaglobulinemia and agammaglobulinemia related to B-cell aplasia can occur in patients after KYMRIAH infusion.
Hypogammaglobulinemia was reported in 53% of patients treated with KYMRIAH for r/r ALL, 17% of patients with r/r DLBCL, and 18% of patients with r/r FL [see Clinical Pharmacology (12.3)].
Monitor immunoglobulin levels after treatment with KYMRIAH and manage using infection precautions, antibiotic prophylaxis, and immunoglobulin replacement standard guidelines.
Immunization with Live Vaccine
The safety of immunization with live vaccines during or following KYMRIAH treatment has not been studied. Vaccination with live vaccines is not recommended for at least 6 weeks prior to the start of lymphodepleting chemotherapy, during KYMRIAH treatment, and until immune recovery following treatment with KYMRIAH.
Pregnant women who have received KYMRIAH may have hypogammaglobulinemia. Assess immunoglobulin levels in newborns of mothers treated with KYMRIAH.
Patients treated with KYMRIAH may develop secondary malignancies or recurrence of their cancer. T cell malignancies have occurred following treatment of hematologic malignancies with BCMA- and CD19- directed genetically modified autologous T cell immunotherapies, including KYMRIAH. Mature T cell malignancies, including CAR-positive tumors, may present as soon as weeks following infusion, and may include fatal outcomes [see Boxed Warning, Adverse Reactions (6.2), Patient Counseling Information (17)].
Monitor life-long for secondary malignancies. In the event that a secondary malignancy occurs, contact Novartis Pharmaceuticals Corporation at 1-844-4KYMRIAH to obtain instructions on patient samples to collect for testing.
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
The safety data described in the WARNINGS AND PRECAUTIONS and in this section reflect exposure to KYMRIAH in three non-randomized, single-arm studies in which 79 pediatric and young adult patients with relapsed/refractory (r/r) B-cell ALL (Study 1: CCTL019B2202), 115 adults with r/r diffuse large B-cell lymphoma (Study 2: CCTL019C2201), and 97 adults with r/r follicular lymphoma (Study 3: CCTL019E2202) received a single dose of CAR-positive viable T cells.
Pediatric and Young Adult r/r B-cell Acute Lymphoblastic Leukemia (ALL) (up to 25 years of age)
Based on a recommended dose which was weight-based, all 79 patients in the Study 1 received a single intravenous dose of KYMRIAH [see Clinical Studies (14.1)]. The most common adverse reactions (> 20%) were CRS (77%), infections-pathogen unspecified (57%), hypogammaglobulinemia (53%), fever (42%), decreased appetite (38%), viral infectious disorders (38%), headache (35%), febrile neutropenia (34%), hemorrhage (32%), musculoskeletal pain (32%), vomiting (32%), encephalopathy (30%), bacterial infectious disorders (29%), diarrhea (29%), hypotension (29%), cough (27%), nausea (27%), pain (25%), hypoxia (25%), tachycardia (24%), edema (23%), fatigue (23%), and acute kidney injury (22%).

Adult r/r Diffuse Large B-cell Lymphoma (DLBCL)
In Study 2, 115 adults with r/r DLBCL received a single intravenous dose of KYMRIAH [see Clinical Studies (14.2)]. The most common adverse reactions (incidence > 20%) were CRS, infections-pathogen unspecified, fever, diarrhea, nausea, fatigue, hypotension, edema, bleeding episodes, dyspnea, and headache.
The study population characteristics were median age of 56 years (range, 22 to 76 years), 80% DLBCL; a median of 3 prior lines of therapy (range, 1 to 6), 49% had a prior autologous hematopoietic stem cell transplantation, and 32% had received prior radiation therapy. One hundred seven patients (93%) received lymphodepleting chemotherapy prior to KYMRIAH, which included fludarabine (n = 85) or bendamustine (n = 22).

Because adverse events to marketed products are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to product exposure.
The following adverse events have been identified during postmarketing use of KYMRIAH.
HIV and the lentivirus used to make KYMRIAH have limited, short spans of identical genetic material (RNA). Therefore, some commercial HIV nucleic acid tests (NATs) may yield false-positive results in patients who have received KYMRIAH.
Risk Summary
There are no available data with KYMRIAH use in pregnant women. No animal reproductive and developmental toxicity studies have been conducted with KYMRIAH to assess whether it can cause fetal harm when administered to a pregnant woman. It is not known if KYMRIAH has the potential to be transferred to the fetus. Based on the mechanism of action, if the transduced cells cross the placenta, they may cause fetal toxicity, including B-cell lymphocytopenia. Therefore, KYMRIAH is not recommended for women who are pregnant, and pregnancy after KYMRIAH administration should be discussed with the treating physician. Report pregnancies to Novartis Pharmaceuticals Corporation at 1-888-669-6682.
In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.
Risk Summary
There is no information regarding the presence of KYMRIAH in human milk, the effect on the breastfed infant, and the effects on milk production. A risk to the breastfed infant cannot be excluded. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for KYMRIAH and any potential adverse effects on the breastfed infant from KYMRIAH or from the underlying maternal condition.
Pregnancy Testing
Pregnancy status of females with reproductive potential should be verified. Sexually active females of reproductive potential should have a pregnancy test prior to starting treatment with KYMRIAH.
Contraception
See the prescribing information for fludarabine and cyclophosphamide for information on the need for effective contraception in patients who receive the lymphodepleting chemotherapy.
There are insufficient exposure data to provide a recommendation concerning duration of contraception following treatment with KYMRIAH.
Infertility
There are no data on the effect of KYMRIAH on male and female fertility.
The safety and efficacy of KYMRIAH have been established in pediatric patients with r/r B-cell ALL. Use of KYMRIAH is supported by a single-arm trial [see Clinical Studies (14.1)] that included 61 pediatric patients with r/r B-cell precursor ALL in the following age groups: 40 children (ages 2 years to less than 12 years) and 21 adolescents (ages 12 years to less than 17 years). No differences in efficacy or safety were observed between the different age subgroups or in comparison to the young adults in the trial.
The safety and efficacy of KYMRIAH in pediatric patients with r/r DLBCL and r/r FL have not been established.
The safety and effectiveness of KYMRIAH have not been established in geriatric patients with r/r B-cell ALL. Clinical studies of KYMRIAH did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects.
KYMRIAH (tisagenlecleucel) is a CD19-directed genetically modified autologous T cell immunotherapy comprised of autologous T cells that are genetically modified using a lentiviral vector to encode an anti-CD19 chimeric antigen receptor (CAR). The CAR is comprised of a murine single-chain antibody fragment (scFv) specific for CD19, followed by a CD8 hinge and transmembrane region that is fused to the intracellular signaling domains for 4-1BB (CD137) and CD3 zeta.
KYMRIAH is prepared from the patient’s peripheral blood mononuclear cells, which are obtained via a standard leukapheresis procedure. The mononuclear cells are enriched for T cells, then transduced with the lentiviral vector containing the anti-CD19 CAR transgene and activated with anti-CD3/CD28 antibody coated beads. The transduced T cells are expanded in cell culture, washed, and formulated into a suspension, which then is cryopreserved. The product must pass a sterility test before release for shipping as a frozen suspension in a patient-specific infusion bag(s). The product is thawed prior to administration [see Dosage and Administration (2.2), How Supplied/Storage and Handling (16)]. The thawed product is a colorless to slightly yellow suspension of cells.
In addition to T cells, other cell populations, including monocytes, NK cells, and B cells, may be present. The formulation contains 31.25% (v/v) of Plasma-Lyte A, 31.25% (v/v) of 5% Dextrose/0.45% sodium chloride, 10% Dextran 40 (LMD)/5% Dextrose, 20% (v/v) of 25% Human Serum Albumin (HSA), and 7.5% (v/v) dimethyl sulfoxide (DMSO).
Pediatric and Young Adult r/r B-cell ALL: A single dose of KYMRIAH may contain up to 2.5 x 108 CAR-positive viable T cells provided in one to three patient-specific infusion bag(s). Based on the patient’s weight reported at the time of leukapheresis, one of two possible dose ranges will be prepared for the patient:
Adult r/r DLBCL and r/r FL: A single dose of KYMRIAH may contain 0.6 to 6.0 x 108 CAR-positive viable T cells provided in one to three patient-specific infusion bag(s).
The actual number of CAR-positive T cells in the product is reported on the Certificate of Analysis (CoA) that is shipped with KYMRIAH. The volume of CAR-positive viable T cells in an infusion bag ranges from 10 mL to 50 mL.
KYMRIAH is a CD19-directed genetically modified autologous T cell immunotherapy which involves reprogramming a patient’s own T cells 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 intracellular signaling domains from 4-1BB (CD137) and CD3 zeta. The CD3 zeta component is critical for initiating T cell activation and antitumor activity, while 4-1BB enhances the expansion and persistence of KYMRIAH. Upon binding to CD19-expressing cells, the CAR transmits a signal to promote T cell expansion, activation, target cell elimination, and persistence of the KYMRIAH cells.
Due to the on-target effect of KYMRIAH, a period of B-cell aplasia is expected.
Among evaluable pediatric and young adult r/r B-cell ALL patients with an ongoing response at Month 24, 33% had no detectable B cells at baseline prior to infusion. At Month 24, 88% had no detectable B cells.
Most adult r/r DLBCL patients had B-cell depletion at baseline prior to infusion due to previous treatment with rituximab. Recovery of B-cell levels were observed with longer follow-up in some of the responding DLBCL patients after KYMRIAH infusion. Among evaluable adult r/r DLBCL and FL patients with an ongoing response at Month 24, all patients had no detectable B cells at baseline prior to infusion or at Month 24.
Following infusion, KYMRIAH exhibited an initial rapid expansion followed by a bi-exponential decline in pediatric and young adult r/r B-cell acute lymphoblastic leukemia (ALL) patients, adult r/r diffuse large B-cell lymphoma patients, and adult r/r follicular lymphoma patients.
A summary of pharmacokinetic parameters of KYMRIAH is provided in Table 10 below.

Description of Pharmacokinetics in Pediatric and Young Adult r/r B-cell ALL (up to 25 years of age)
The Cmax and AUC0-28d were similar between CR/CRi patients compared with non-responding (NR) patients.
KYMRIAH was present in the blood as well as bone marrow and was measurable beyond 2 years. Blood to bone marrow partitioning suggested that KYMRIAH distribution in bone marrow was 44% of that present in blood at Day 28 while at Months 3 and 6 KYMRIAH distributed at 67% and 69%, respectively, indicating high distribution to bone marrow.
Children < 10 years and between 10-18 years of age had similar- to 1.7-fold higher Cmax and AUC0-28d than adults. Due to small sample size and high variability, it is difficult to assess the impact of age on the pharmacokinetics of KYMRIAH.
Description of Pharmacokinetics in Adult r/r DLBCL
The Cmax and AUC0-28d were similar between responding and non-responding (NR) patients.
KYMRIAH was present in adult r/r DLBCL patients up to 18 months in peripheral blood and up to 9 months in the bone marrow for patients having a complete response (CR). The median time of maximal expansion of transgene levels (Tmax) in peripheral blood occurred at 9-10 days in both responding and non-responding patients.
Description of Pharmacokinetics in Adult r/r FL
KYMRIAH has been detected for up to 18 months in peripheral blood and up to 3 months in bone marrow for patients who achieved a response. The median time of maximal expansion of transgene levels (Tmax) in peripheral blood occurred at 10 days in responding and 13 days in non-responding patients.
The blood to bone marrow partitioning in bone marrow was nearly 50% at Month 3 in responding patients.
The geometric mean AUC0-28d value of responders was 183% higher compared to non-responders, while the geometric mean Cmax value was 108% higher in responders compared to non-responders. Considering the high inter-individual variability, small number of non-responders, overlapping expansion ranges observed between responders and non-responders, the exposure differences should be interpreted with caution.
Tocilizumab and Corticosteroid used for CRS Management
Some patients required tocilizumab and corticosteroids for the management of CRS. KYMRIAH continues to expand and persist following treatment as per the CRS management algorithm (see Table 1). Patients who have higher expansion tended to have higher CRS Grades [see Warnings and Precautions (5.1)].
Pediatric and young adult r/r B-cell ALL patients (N = 28) treated with tocilizumab had 298% and 183% higher KYMRIAH AUC0-28d and Cmax, respectively, as compared to patients (N = 46) who did not receive tocilizumab. In addition, patients who received corticosteroids for CRS management (N = 17) had 280% higher AUC0-28d compared with patients who did not receive corticosteroids (N = 31).
Adult r/r DLBCL patients treated with tocilizumab (N = 18) had 238% (n = 14) and 311% (n = 16) higher KYMRIAH AUC0-28d and Cmax, respectively, as compared to patients (N = 97) who did not receive tocilizumab. In addition, patients who received corticosteroids for CRS management (N = 12) had 104% and 179% higher AUC0-28d and Cmax, respectively, as compared with patients who did not receive corticosteroids (N = 79).
Adult r/r FL patients treated with tocilizumab (N = 14) had 245% (n = 12) and 312% (n = 11) higher KYMRIAH AUC0-28d and Cmax, respectively, as compared to patients (N = 76) who did not receive tocilizumab. Three patients received corticosteroids for CRS management while all other patients received corticosteroids for other reasons, therefore a formal comparison for exposure differences by use of corticosteroids cannot be performed.
Hepatic and renal impairment studies of KYMRIAH were not conducted.
The observed incidence of anti-drug antibodies is highly dependent on the sensitivity and specificity of the assay. Differences in assay methods preclude meaningful comparisons of the incidence of anti-product antibodies in the studies described below with the incidence of anti-product antibodies in other studies, including those of KYMRIAH or of other similar products.
In clinical studies, humoral immunogenicity of KYMRIAH was measured by determination of anti-murine CAR19 antibodies (anti-mCAR19) in serum pre- and post-administration. The majority of patients, 91% in Study 1, 94% in Study 2, and 66% in Study 3, tested positive for pre-dose anti-mCAR19 antibodies prior to KYMRIAH infusion. Treatment induced anti-mCAR19 antibodies were detected in 9% and 33% of the patients in Study 2 and Study 3, respectively. However, the preexisting and treatment-induced antibodies were not associated with an impact on clinical response and did not have an impact on the initial expansion and persistence of KYMRIAH. Persistence of KYMRIAH was similar between patients with positive post-infusion anti-mCAR19 antibodies compared with patients with negative post-infusion anti-mCAR19 antibodies. There is no evidence that the presence of preexisting and treatment-induced anti-mCAR19 antibodies impact the safety or effectiveness of KYMRIAH.
T cell immunogenicity responses were not observed in r/r ALL, r/r DLBCL, or r/r FL patients.
Genotoxicity assays and carcinogenicity assessment in rodent models were not performed for KYMRIAH. I n vitro expansion studies with transduced T cells (KYMRIAH) from healthy donors and patients showed no evidence for transformation and/or immortalization of T cells. I n vivo studies in immunocompromised mice did not show signs of abnormal cell growth or signs of clonal cell expansion for up to 7 months after cell injection. A genomic insertion site analysis was performed on KYMRIAH products from 14 individual donors (12 patients and 2 healthy volunteers). There was no evidence for preferential integration near genes of concern, or preferential outgrowth of cells harboring integration sites of concern.
No studies on the effects of KYMRIAH on fertility have been conducted.
The efficacy of KYMRIAH in pediatric and young adults with r/r B-cell precursor ALL was evaluated in an open-label, multicenter single-arm trial (Study 1: CCTL019B2202; NCT02435849). In total, 107 patients were screened, 88 were enrolled, 68 were treated, and 63 were evaluable for efficacy. Nine percent of the enrolled patients did not receive the product due to manufacturing failure. The 63 evaluable patients included 35 males and 28 females of median age 12 years (range, 3 to 23 years). Seventy-three percent of patients were White, 10% were Asian, and 17% were of other races. Six (10%) had primary refractory disease, 30 (48%) had one prior stem cell transplantation, 5 patients (8%) had two stem cell transplantations. Treatment consisted of lymphodepleting chemotherapy (fludarabine 30 mg/m2 daily for 4 days and cyclophosphamide 500 mg/m2 daily for 2 days) followed by a single dose of KYMRIAH. Of the 22 patients who had a WBC count < 1000/µL, 20 received lymphodepleting chemotherapy prior to KYMRIAH while 2 received KYMRIAH infusion without lymphodepleting chemotherapy. Fifty-three patients received bridging chemotherapy between time of enrollment and lymphodepleting chemotherapy.
The efficacy of KYMRIAH was established on the basis of complete remission (CR) within 3 months after infusion, the duration of CR, and proportion of patients with CR and minimal residual disease (MRD) < 0.01% by flow cytometry (MRD-negative) (Table 11). Among the 63 infused patients, 52 (83%) achieved CR/CRi, all of which were MRD-negative. With a median follow-up of 4.8 months from response, the median duration of CR/CRi was not reached (range, 1.2 to 14.1+ months). Median time to onset of CR/CRi was 29 days with onset of CR/CRi between 26 and 31 days for 50/52 (96%) responders. The stem cell transplantation rate among those who achieved CR/CRi was 12% (6/52). Table 11 shows the efficacy results from this study.
| 1CR/CRi was calculated based on all patients who received KYMRIAH and completed at least 3 months follow-up or discontinued earlier prior to the data cut-off. Requires remission status to be maintained for at least 28 days without clinical evidence of relapse. 2The null hypothesis of CR/CRi less than or equal to 20% was rejected. 3CR (complete remission) was defined as less than 5% of blasts in the bone marrow, no evidence of extramedullary disease, and full recovery of peripheral blood counts (platelets greater than 100,000/microliter and absolute neutrophil counts [ANC] greater than 1,000/microliter) without blood transfusion. 4CRi (complete remission with incomplete blood count recovery) was defined as less than 5% of blasts in the bone marrow, no evidence of extramedullary disease, and without full recovery of peripheral blood counts with or without blood transfusion. 5MRD (minimal residual disease) negative was defined as MRD by flow cytometry less than 0.01%. 6The null hypothesis of MRD-negative remission rate less than or equal to 15% was rejected. 7DOR (duration of remission) was defined as time since onset of CR or CRi to relapse or death due to underlying cancer, whichever is earlier, censoring for new cancer therapy including stem cell transplantation (N = 52). 8Not Estimable. | |

The efficacy and safety of KYMRIAH was evaluated in an open-label, multicenter, single-arm trial (Study 2: CCTL019C2201; NCT02445248). Eligible patients were ≥ 18 years of age with relapsed or refractory DLBCL, who received ≥ 2 lines of chemotherapy, including rituximab and anthracycline, or relapsed following autologous hematopoietic stem cell transplantation (HSCT). The study excluded patients with active central nervous system malignancy, prior allogenic HSCT, an ECOG performance status ≥ 2, a creatinine clearance < 60, alanine aminotransferase > 5 times normal, cardiac ejection fraction < 45%, or absolute lymphocyte concentration less than 300/µL.
Following 2 to 11 days after completion of lymphodepleting (LD) chemotherapy consisting of either fludarabine (25 mg/m2 intravenously daily for 3 days) and cyclophosphamide (250 mg/m2 intravenously daily for 3 days starting with the first dose of fludarabine) or bendamustine (90 mg/m2 intravenously daily for 2 days), KYMRIAH was administered as a single intravenous infusion. Bridging chemotherapy between leukapheresis and LD chemotherapy was permitted to control disease burden. LD chemotherapy could be omitted if the white blood cell count was < 1000 cells/µL. The major efficacy outcome measures were objective response rate per Lugano criteria [2014] as assessed by an independent review committee and duration of response.
Of the 160 patients enrolled, 106 patients received tisagenlecleucel, including 92 patients who received product manufactured in the U.S. and were followed for at least 3 months or discontinued earlier. Eleven out of 160 patients enrolled did not receive tisagenlecleucel due to manufacturing failure. Thirty-eight other patients did not receive tisagenlecleucel, primarily due to death (n = 16), physician decision (n = 16), and adverse events (n = 3).
Of the 92 patients receiving KYMRIAH, 90% received physician’s choice of bridging chemotherapy in the interval between start of screening and KYMRIAH infusion, among whom the median number of bridging chemotherapy regimens was 1 (range, 1 to 5) with 83% of patients receiving ≤ 2 regimens. A retrospectively identified sub-group of 68 patients was evaluable for the major efficacy outcome measures. Patients included in this sub-group had either had no bridging chemotherapy, or had imaging that showed measurable disease after completion of bridging chemotherapy, prior to KYMRIAH infusion. Of the 24 patients not included, 8 had no evidence of disease at baseline prior to KYMRIAH infusion, 15 did not have baseline imaging following bridging chemotherapy, and 1 was excluded because of initial misclassification of a neuroendocrine tumor as DLBCL.
Among the efficacy evaluable population of 68 patients, the baseline characteristics were median age 56 years (range, 22 to 74 years); 71% male; 90% White, 4% Asian, and 3% Black or African American; 78% had primary DLBCL not otherwise specified (NOS) and 22% had DLBCL following transformation from follicular lymphoma, of whom 17% were identified as high grade; and 44% had undergone prior autologous HSCT. The median number of prior therapies was 3 (range, 1 to 6), 56% had refractory disease and 44% relapsed after their last therapy. Ninety percent of patients received lymphodepleting chemotherapy (66% of patients received fludarabine and 24% received bendamustine) and 10% did not receive any LD chemotherapy. The median time from leukapheresis and cryopreservation to KYMRIAH infusion was 113 days (range, 47 to 196 days). The median dose was 3.5 × 108 CAR-positive viable T cells (range, 1.0 to 5.2 × 108 cells). Seventy-three percent of patients received KYMRIAH in the inpatient setting.
Efficacy was established on the basis of CR rate and duration of response (DOR), as determined by an independent review committee (Table 12 and Table 13). The median time to first response to KYMRIAH (CR or PR) was 0.9 months (range, 0.7 to 3.3 months). The median duration of response was not reached. Response durations were longer in patients who achieved CR, as compared to patients with a best response of partial response (PR) (Table 13). Of the 22 patients who experienced a CR, 9 achieved this status by 1 month, 12 more by month 3, and the last by month 6 after KYMRIAH infusion.

The efficacy of KYMRIAH was evaluated in a multicenter, single-arm, open-label trial (Study 3: CCTL019E2202; NCT03568461) that included patients who were refractory to or relapsed within 6 months after completion of two or more lines of systemic therapy (including an anti-CD20 antibody and an alkylating agent), relapsed during or within six months after completion of an anti-CD20 antibody maintenance therapy following at least two lines of therapy, or relapsed after autologous hematopoietic stem cell transplant (HSCT). The trial excluded patients with active or serious infections, transformed lymphoma, or other aggressive lymphomas, prior allogeneic HSCT, or disease with active CNS involvement. Following lymphodepleting (LD) chemotherapy, KYMRIAH was administered as a single dose intravenous infusion with a target dose of 0.6 to 6.0 × 108 CAR-positive viable T cells. The median dose administered was 2.06 × 108 CAR-positive viable T cells (range, 0.1 to 6.0 × 108 CAR-positive viable T cells). The LD chemotherapy regimen consisted of either fludarabine (25 mg/m2 intravenously daily for 3 days) and cyclophosphamide (250 mg/m2 intravenously daily for 3 days starting with the first dose of fludarabine) or bendamustine (90 mg/m2 IV daily for 2 days); bridging chemotherapy between leukapheresis and LD chemotherapy was permitted as needed. Of the 90 patients included in the primary efficacy analysis, 40 patients (45%) were treated with bridging therapies. The most commonly used agents (in ≥ 5% of patients) were rituximab (22%), dexamethasone (13%), gemcitabine (12%), prednisone (11%), oxaliplatin (8%), etoposide (8%), and vincristine (6%).
Of 98 patients who were enrolled and underwent leukapheresis, 97 patients received infusion with KYMRIAH and one patient without measurable disease did not receive KYMRIAH. There were no manufacturing failures for the 98 enrolled patients. Of the 97 patients infused with KYMRIAH, the efficacy evaluable population, as specified in the protocol, included the first 90 patients with measurable disease who received KYMRIAH consecutively and had at least 9 months follow-up from first objective response or discontinued earlier.
Among the 90 patients with FL included in the efficacy analysis, the median age was 58 years (range, 29 to 73 years), 31% were female, 78% were White, 10% were Asian, and 1% were Black or African American. The median number of prior therapies was 4 (range, 2 to 13), with 24% receiving 2 prior lines, 21% receiving 3 prior lines, and 54% receiving ≥4 prior lines. Eighty-seven percent had Stage III-IV disease at study entry, 64% had bulky disease, 36% had a prior autologous HSCT, 79% were refractory to the most recent regimen, and 66% had progression within 24 months of initiating their first anti-CD20 combination therapy (POD24).
Efficacy was established on the basis of objective response rate and duration of response (DOR) as determined by an independent review committee (Table 14 and Table 15). The first disease assessment was scheduled to be performed at Month 3 post-infusion; the median time to first response was 2.9 months (range, 0.6 to 6.0 months). All responders achieved their response (complete response [CR] or partial response [PR]) at the first performed post-infusion disease assessment.
| aTwo patients, included in the Primary Efficacy Population, with best overall response of CR, had their disease relapsed more than 6 months after the last line of therapy. bOf the 30 patients who initially achieved a PR, 14 patients (47%) converted to a CR, including 10 patients at the next subsequent visit and within 6 months post-infusion. | ||

Advise the patient to read the FDA-approved patient labeling (Medication Guide).
Ensure that patients understand the risk of manufacturing failure. This has been reported in up to 9% of manufacturing attempts. In case of a manufacturing failure, a second manufacturing of KYMRIAH may be attempted. In addition, while the patient awaits the product, additional chemotherapy (not the lymphodepletion) may be necessary and may increase the risk of adverse events during the pre-infusion period.
Prior to infusion, advise patients of the following risks:
Patients should be instructed to contact Novartis Pharmaceuticals Corporation at 1-844-4KYMRIAH if they get secondary malignancies [see Warnings and Precautions (5.8)].

| This Medication Guide has been approved by the U.S. Food and Drug Administration. | Revised: June 2025 |
| MEDICATION GUIDE KYMRIAH® (pronounced KIM-RYE-AH) (tisagenlecleucel) suspension, for intravenous infusion | |
| Read this Medication Guide before you start your KYMRIAH treatment. The more you know about your treatment, the more active you can be in your care. Talk with your healthcare provider if you have questions about your health condition or treatment. Reading this Medication Guide does not take the place of talking with your healthcare provider about your treatment. | |
| What is the most important information I should know about KYMRIAH? KYMRIAH may cause side effects that are severe or life-threatening. Call your healthcare provider or get emergency help right away if you get any of the following: | |
| |
| What is KYMRIAH? KYMRIAH is made from your own white blood cells and is a prescription cancer treatment used in patients up to 25 years old who have acute lymphoblastic leukemia (ALL) that is either relapsing (went into remission, then came back) or refractory (did not go into remission after receiving other leukemia treatments). It is also used in patients with large B-cell lymphoma or follicular lymphoma, two types of non-Hodgkin lymphoma, that have relapsed or are refractory after having at least two other kinds of treatment. | |
| How will I get KYMRIAH? Since KYMRIAH is made from your own white blood cells, your healthcare provider has to take some of your blood. This is called “leukapheresis.” It takes 3 to 6 hours and may need to be repeated. A tube (intravenous catheter) will be placed in your vein to collect your blood. Your blood cells are frozen and sent to the manufacturing site to make KYMRIAH. It takes about 3-4 weeks from the time your cells are received at the manufacturing site and shipped back to your healthcare provider, but the time may vary. While waiting for KYMRIAH to be made, your healthcare provider may give you therapy to stabilize your cancer. In addition, before you get KYMRIAH, your healthcare provider may give you chemotherapy for a few days to prepare your body. When your body is ready, your healthcare provider will give you KYMRIAH through a tube (intravenous catheter) in your vein. This usually takes less than one hour. You should plan to stay close to a healthcare facility for at least 2 weeks after getting KYMRIAH. Your healthcare provider will check to see if your treatment is working and help you with any side effects that occur. | |
What should I avoid after receiving KYMRIAH?
| |
| What are the possible or reasonably likely side effects of KYMRIAH? The most common side effects of KYMRIAH are:
| |
| KYMRIAH can increase the risk of life-threatening infections that may lead to death. Tell your healthcare provider right away if you develop fever, chills, or any signs or symptoms of an infection.
KYMRIAH can lower one or more types of your blood cells (red blood cells, white blood cells, or platelets). After treatment, your healthcare provider will test your blood to check for this. Tell your healthcare provider right away if you get a fever, are feeling tired, weak, or short of breath, or have bruising or bleeding. Having KYMRIAH in your blood may cause a false-positive HIV test result by some commercial tests. KYMRIAH may increase your risk of getting cancers, including certain types of blood cancers. Your healthcare provider should monitor you for this. These are not all the possible side effects of KYMRIAH. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088. | |
| General information about the safe and effective use of KYMRIAH. Medicines are sometimes prescribed for purposes other than those listed in a Medication Guide. Do not use KYMRIAH for a condition for which it was not prescribed. Talk to your healthcare provider about any concerns. You can ask your healthcare provider for information about KYMRIAH that is written for healthcare professionals. Distributed by: Novartis Pharmaceuticals Corporation, East Hanover, New Jersey 07936.
