Description/Scope

This document addresses the uses of axicabtagene ciloleucel (Kite Pharma, Inc, Santa Monica, CA) autologous chimeric antigen receptor (CAR) T-cell, CD3/CD28-based therapy, that targets the CD19 surface antigen expressed in B cell malignancies, in particular, non-Hodgkin’s lymphoma (NHL). Axicabtagene ciloleucel is produced by engineering an individual’s own functioning immune cells to express tumor antigen recognition signals that target and destroy malignant cells in some types of cancer.

Axicabtagene ciloleucel is considered medically necessary in individuals with non-Hodgkin’s lymphoma (NHL) when all of the following criteria in 1 through 6 are met:

  1. 18 years of age or older; and
  2. Histologically confirmed diagnosis of one of the following types of aggressive NHL:
    1. Diffuse large B-cell lymphoma (DLBCL), not otherwise specified; or
    2. High-grade B-cell lymphoma; or
    3. Primary mediastinal large B-cell lymphoma; or
    4. Transformed follicular lymphoma; and
  3. Relapsed or refractory disease, defined as progression after two or more lines of systemic therapy (which may or may not include therapy supported by autologous stem cell transplant); and
  4. Must have received adequate prior therapy including, at a minimum, all of the following:
    1. An anthracycline-containing chemotherapy regimen; and
    2. For CD20+ disease, anti-CD20 monoclonal antibody; and
    3. For subjects with transformed follicular lymphoma, prior chemotherapy for follicular lymphoma with chemotherapy refractory disease after transformation to DLBCL; and
  5. Documentation of all of the following clinical findings:
    1. Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1; and
    2. Absolute neutrophil count (ANC) ≥ 1000/uL; and
    3. Absolute lymphocyte count (ALC) > 100/uL; and
    4. Platelet count ≥ 75,000/uL; and
  6. One-time, single administration treatment.

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

Investigational and Not Medically Necessary:

Axicabtagene ciloleucel is considered investigational and not medically necessary as a treatment for relapsed or refractory non-Hodgkin’s lymphoma when the medically necessary criteria are not met, and for all other indications, including but not limited to:

  1. Any central nervous system (CNS) disease (for example, brain metastases, CNS lymphoma, and a history or presence of CNS disorders such as seizure disorder, cerebrovascular ischemia/hemorrhage, dementia, cerebellar disease, or autoimmune disease with CNS involvement);
  2. History of allogeneic stem cell transplant, chimeric antigen receptor therapy or other genetically modified T-cell therapy;
  3. Active, uncontrolled infection;
  4. Human immunodeficiency virus (HIV);
  5. Hepatitis B or C (if viral load is detectable).
Rationale

 

On October 18, 2017, the U.S. Food and Drug Administration (FDA) approved axicabtagene ciloleucel for the treatment of adults with “relapsed or refractory large B-cell lymphoma after two or more lines of systemic therapy, including 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”. Axicabtagene ciloleucel was granted breakthrough and priority review status by the FDA (Product Information [PI] Label, 2017).

 

FDA approval was based on the results of a single arm, open-label, multicenter, phase 1/2 study (ZUMA-1) in 111 adults (18 years and older) diagnosed with DLBCL, primary mediastinal B-cell lymphoma or transformed follicular lymphoma, which are types of aggressive NHL (Neelapu, 2016). A total of 101 study participants were successfully treated with a single infusion of axicabtagene ciloleucel. All study enrollees received lymphodepleting chemotherapy (fludarabine and cyclophosphamide) prior to infusion with the axicabtagene ciloleucel. Inclusion criteria included chemotherapy refractive disease, prior treatment with an adequate chemotherapy regimen, at least one measurable lesion per revised International Working Group (IWG) Response Criteria, Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1, absolute neutrophil count (ANC) ≥ 1000/uL, absolute lymphocyte count (ALC) > 100/uL, platelet count ≥ 75,000/uL, and adequate organ function. Study exclusion criteria included a history of malignancy other than non-melanoma skin cancer or carcinoma in situ (for example, cervix, bladder, breast), history of allogeneic stem cell transplantation, prior therapy with a genetically modified T-cell therapy, presence of an uncontrolled infection, positive for human immunodeficiency virus (HIV), hepatitis B or C virus (history of hepatitis B or C is permitted if the viral load is undetectable per quantitative polymer chain reaction [PCR] and/or nucleic acid testing), subjects with detectable central nervous system (CNS) disease, or brain metastases, a history of CNS lymphoma, or a history or presence of CNS disorders such as seizure disorder, cerebrovascular ischemia/hemorrhage, dementia, cerebellar disease, or any autoimmune disease with CNS involvement. The study met its primary endpoint with an objective response rate of 72% (p<0.0001); 51% complete responses and 21% partial responses. With a median follow-up of 8.7 months, the median overall survival has not yet been reached. The overall duration of response was 9.2 months and has not yet been reached in those who achieved a complete response. The most common grade 3 or higher adverse events included decreased lymphocyte count (100%), decreased white blood cell count (96%), neutropenia (93%), anemia (66%), thrombocytopenia (58%) and encephalopathy (29%). Other grade 3 or higher serious adverse events that occurred in study participants included hemophagocytic lymphohistiocytosis (1%), cardiac failure (6%), cardiac arrest (4%), cytokine release syndrome (13%), and pulmonary edema (9%) (PI Label, 2017).

 

The National Comprehensive Cancer Network® (NCCN®) Clinical Practice Guidelines (CPG) for NHL (2017) currently has a 2A recommendation for the use axicabtagene ciloleucel as a therapeutic option in the treatment of adults with relapsed or refractory large B-cell lymphoma after two or more lines of systemic therapy.

 

Axicabtagene ciloleucel is also being investigated for safety and efficacy in combination with atezolizumab for NHL, in children and young adults with NHL, and for the treatment of adults with relapsed/refractory acute lymphoblastic leukemia (ALL), multiple myeloma and mantle cell lymphoma (ClinicalTrials.gov, 2017).

 

Background/Overview

NHL is one of the most common cancers in the United States, accounting for approximately 4% of all cancer diagnoses. The National Cancer Institute (NCI) estimates that approximately 72,000 new cases of NHL will be diagnosed in 2017 (NCI, 2017). DLBCL is the most common type of NHL; one out of every three cases (American Cancer Society, 2017). While DLBCL is a relatively treatable malignancy, response rates to second-line therapy and beyond are much poorer and vary from about 14% to 60% (Locke, 2017).

Axicabtagene ciloleucel is a type of chimeric antigen receptor therapy (CAR-T). CAR T-cells are a novel therapeutic strategy proposed for the treatment of several malignancies, including relapsed/refractory DLBCL. The process of producing CAR-T cells begins with harvesting peripheral blood cells from an individual. The T-cells are isolated and genetically engineered to recognize an antigen on targeted tumor cells (the resulting genetically engineered cells are CAR-T cells). These cells are then stimulated to multiply and the final product is infused back into the individual, engineered to target and destroy malignant cells. (Locke, 2017).
