Adoptive Immunotherapy
DESCRIPTION
The spontaneous regression of certain cancers supports the idea that an individual’s immune system is sometimes capable of delaying tumor progression and, on rare occasions, can eliminate tumors altogether. These observations have led to research into various immunologic therapies designed to stimulate the individual’s own immune system. Adoptive immunotherapy is a method of activating lymphocytes and/or other types of cells for the treatment of cancer and other diseases. Cells are removed from the individual, processed, and reinfused.
These therapies can be categorized into active specific (e.g., increasing select populations of cytotoxic T lymphocytes with specific reactivity to tumor antigens), active non-specific (i.e., the use of interleukin-2 to increase the number of activated lymphocytes), and passive immunotherapy (i.e., transfer of specific immune cells such as cytotoxic T-lymphocytes or lymphokine-activated killer cells to produce antibodies). Protocols vary, but usually include these common steps:
Lymphocyte harvesting (either from peripheral blood or from tumor biopsy)
Propagation of tumor-specific lymphocytes in vitro using various immune modulators
Selection of lymphocytes with reactivity to tumor antigens with enzyme-linked immunosorbent assay
Lymphodepletion of the host with immunosuppressive agents
Adoptive transfer (i.e., transfusion) of lymphocytes back into the tumor-bearing host
POLICY
Adoptive immunotherapy, using adoptive cellular therapy for the administration of cytotoxic T lymphocytes, cytokine-induced killer cells, tumor-infiltrating lymphocytes, antigen-loaded autologous dendritic cells, or genetically engineered T cells for treatment of malignancy, is considered investigational. (Note: except for therapies (e.g., axicabtagene ciloleucel (Yescarta™) and tisagenlecleucel (Kymriah®) that are addressed separately in BCBST pharmacy policies as medically necessary)
IMPORTANT REMINDERS
Any specific products referenced in this policy are just examples and are intended for illustrative purposes only.

We develop Medical Policies to provide guidance to Members and Providers. This Medical Policy relates only to the services or supplies described in it. The existence of a Medical Policy is not an authorization, certification, explanation of benefits or a contract for the service (or supply) that is referenced in the Medical Policy. For a determination of the benefits that a Member is entitled to receive under his or her health plan, the Member's health plan must be reviewed. If there is a conflict between the medical policy and a health plan or government program (e.g., TennCare), the express terms of the health plan or government program will govern.
ADDITIONAL INFORMATION
The evidence for adoptive immunotherapy in individuals with various types of cancer includes randomized controlled trials (RCTs), nonrandomized comparative studies, and uncontrolled trials. The impact of adoptive immunotherapy on health outcomes (e.g., increased survival, improved quality of life) has yet to be clarified. Current guidelines from the National Comprehensive Cancer Network (NCCN) do not include recommendations for adoptive immunotherapy.
