Status: Reviewed Last Review Date:    05/03/2018


This document addresses uses of tisagenlecleucel (Kymriah, Novartis Pharmaceuticals Corporation, East Hanover, NJ), an autologous chimeric antigen receptor (CAR) T-cell immunotherapy that targets the CD19 surface antigen expressed in B cell malignancies. Tisagenlecleucel is produced by genetically engineering an individual’s own functioning immune cells to express tumor antigen recognition signals that target and destroy malignant cells in certain types of B-cell precursor cancer.

Position Statement

Medically Necessary:

Tisagenlecleucel is considered medically necessary for the treatment of B-cell acute lymphoblastic leukemia (ALL), when all of the following criteria are met:

  1. Disease is considered refractory, or in second or later relapse, in any of the following scenarios:
    1. Second or later bone marrow relapse; or
    2. Bone marrow relapse after allogeneic stem cell transplant; or
    3. Primary refractory or chemo-refractory after relapse; and
  2. Documentation of CD19 tumor expression; and
  3. Pediatric or young adult (25 years of age or younger); and
  4. Performance score on Karnofsky or Lansky Scale is greater than or equal to 50% or Eastern Cooperative Oncology Group (ECOG) performance score is 0-3; and
  5. One-time, single administration treatment.

Note: According to the black box warning in the FDA Product Information Label (2017), tisagenlecleucel should be administered at a designated treatment center that has received site certification.

Investigational and Not Medically Necessary:

Tisagenlecleucel is considered investigational and not medically necessary as a treatment for B-cell ALL, when the medically necessary criteria are not met, and for all other indications, including but not limited to:

  1. Use as first-line therapy for ALL;
  2. Use in combination with other chemotherapy agents;
  3. Repeat treatment in individuals who have received tisagenlecleucel or other CAR-T treatment previously.

On August 30, 2017, tisagenlecleucel received approval by the U.S. Food and Drug Administration (FDA) for the treatment of children and young adults, 25 years of age or younger, with B-cell acute lymphoblastic leukemia (ALL) that is refractory or in second or later relapse (FDA Product Information [PI] Label, 2017). Tisagenlecleucel was granted priority review and breakthrough therapy designations by the FDA.

FDA approval of tisagenlecleucel was based on a single arm, open-label, multi-center, phase II study to determine the efficacy and safety of a single infusion of tisagenlecleucel in children and young adults with relapsed/refractory B-cell ALL (ELIANA; NCT 02435849). A total of 63 study participants were enrolled and included in the interim analysis (median follow-up 4.8 months). The study inclusion criteria included age 3 years at screening to 21 years at time of diagnosis, positive for CD19 tumor expression, adequate organ function, bone marrow with ≥ 5% lymphoblasts by morphologic assessment at screening, life expectancy of at least 12 weeks, and Karnofsky (participants age ≥ 16 years) or Lansky (participants age < 16 years) performance status of ≥ 50 at screening. Participants were excluded from the study based on criteria which included the following: isolated extra-medullary disease relapse, diagnosis of a concomitant genetic syndrome (for example, Fanconi anemia, Kostmann syndrome, Shwachman syndrome or any other known bone marrow failure syndrome), Burkitt's lymphoma/leukemia (i.e. mature B-cell ALL), prior malignancy (except carcinoma in situ of the skin or cervix treated with curative intent and with no evidence of active disease), treatment with a prior gene therapy product or anti-CD19/anti-CD3 therapy, active or latent hepatitis B or C, or any uncontrolled infection, human immunodeficiency virus (HIV) positive test, presence of grade 2 to 4 acute or extensive chronic graft-versus-host disease (GVHD), and active central nervous system (CNS) involvement by malignancy (defined by CNS-3 per National Comprehensive Cancer Network® [NCCN] guidelines). Study participants were primary refractory, chemo-refractory after first relapse, relapsed after second-line therapy or ineligible for allogeneic SCT. Most study enrollees received lymphodepleting chemotherapy (fludarabine and cyclophosphamide) prior to infusion with tisagenlecleucel (Grupp, 2017). A total of 63% (n=40) of study participants achieved a complete remission (CR) and 19% (n=12) achieved a CR with incomplete blood count recovery (CRi). The primary outcome, overall remission rate (ORR=CR+Cri), was 83% (n=54). Secondary objectives included minimal residual disease (MRD), relapse-free survival (RFS), overall survival (OS) and safety. The 6-month OS was 89% and the disease-free survival was 60%. All participants who achieved a CR or CRi also tested negative for minimal residual disease (95% confidence interval [CI], 71-91; p<0.0001). With a median follow-up of 4.8 months from response, the median duration of CR/CRi was not reached (range: 1.2-14.1+ months). A total of 11 participants died after receiving an infusion with tisagenlecleucel; 7 were disease-related, 3 were attributed to infections, and 1 to intracerebral hemorrhage. Cytokine release syndrome (CRS) occurred in a total of 79% of study participants; 49% of CRS was grade 3 or 4. Treatment with anti-cytokine therapy, high dose vasopressors, invasive ventilation, and dialysis were needed to stabilize participants that developed CRS. There were no CRS-related deaths and no cases of cerebral edema reported (FDA PI Label, 2017). In 2018, Maude and colleagues published the final analysis from this clinical trial with a median follow-up of 13.1 months (range, 2.1 to 23.5 months) and a total of 75 participants enrolled. The final ORR, the key endpoint, was 81% (95% CI, 71-89%); 60% (n=45) achieved a CR, and 21% (n=16) had CRi. As in the interim analysis, the median duration of CR/CRi was not reached. The rate of event-free survival was 73% (95% CI, 60-82%) at 6 months and 50% (95% CI, 35-64%) at 12 months; median event-free survival was also not reached. The OS among the 75 participants who were infused with tisagenlecleucel was 90% (95% CI, 81-95%) 6 months following infusion and 76% (95% CI, 63-86) after 12 months. In this final analysis, 88% (n=66) of the 75 study participants had a grade 3 or 4 adverse event; 73% (n=55) of which were tisagenlecleucel-related. CRS occurred in 77% (n=58) of participants, 60% (n=35) of which were admitted to the intensive care unit for management of the CRS. Of the 58 individuals with CRS, 67% (n=28) received tocilizumab for management. In addition to the 11 deaths reported in the interim analysis, an additional 8 participants died before the final analysis (n=19 deaths for study duration); 2 occurred within the first 30 days after transfusion.

In 2014, Maude and colleagues published the results of a phase II clinical trial in children and adults diagnosed with relapsed/refractory ALL (n=30). A total of 25 children and young adults (5-22 years of age) and 5 older adults (26-60 years of age) received tisagenlecleucel. CR was achieved in 27 study participants (90%), including 2 with blinatumomab-refractory disease and 15 who had previously undergone stem-cell transplantation. There was a 6-month event-free survival rate of 67% (95% CI, 51-88%) and an OS rate of 78% (95% CI, 65-95). All study participants developed CRS. Severe CRS developed in 27% of participants and was associated with a higher disease burden prior to infusion. CRS was effectively treated with the anti-interleukin-6 receptor antibody, tocilizumab (Maude, 2014).

The NCCN Clinical Practice Guidelines (CPG) for ALL (V1.2018) has a 2A recommendation for individuals under the age of 26 with refractory disease or for those with two or more relapses who have experienced treatment failure with at least two tyrosine kinase inhibitors (TKIs).

Tisagenlecleucel is also being investigated for safety and efficacy in adult ALL, relapsed/refractory diffuse large B-cell lymphoma, multiple myeloma, lymphocytic leukemia and Hodgkin’s lymphoma.


ALL is an aggressive type of leukemia characterized by the proliferation of immature lymphoid cells in the bone marrow, peripheral blood and other organs. In 2018, there will be an estimated 5960  new cases of ALL and 1470 deaths (American Cancer Society, 2018). ALL is the most common cancer diagnosed in children in the United States and occurs at an annual rate of approximately 41 cases per 1 million people aged 0 to 14 years and approximately 17 cases per 1 million people aged 15 to 19 years. On average, approximately 3100 children and young adults (<20 years old) are diagnosed with ALL each year (National Cancer Institute, 2017). Although more than 80% of individuals treated for ALL achieve a CR, approximately 15-20% will relapse (Oskarsson, 2016). At this time, hematopoietic stem cell transplant (HSCT) is the most effective treatment option for relapsed/refractory ALL. Achievement of CR is a vital step in the transplantation process, but many individuals are ineligible due to failure to achieve this remission (Topp, 2015).

CAR-T therapy may play an important role as a bridge to transplant by providing another therapeutic option to induce remission in individuals who would otherwise have been ineligible for a HSCT due to progression of disease; tisagenlecleucel is a type of CAR-T therapy (NCCN, 2018).

The process of producing tisagenlecleucel begins with harvesting peripheral blood cells from an individual. The T-cells are isolated and genetically engineering to recognize CD19 on targeted tumor cells (the genetically engineered cells are called CAR-T cells). These cells are then stimulated to multiply and the resulting product is infused back into the individual, reengineered to target and destroy malignant cells expressing CD19 (NCCN, 2018).
