Donor Lymphocyte Infusion for Malignancies Treated with an Allogeneic Hematopoietic Cell Transplant

Policy Number: MP-496

Latest Review Date: March 2024

Category: Surgical                                                                 

POLICY:

Donor lymphocyte infusion (DLI) may be considered medically necessary when it is performed following allogeneic-hematopoietic cell transplantation (HCT) that was originally considered medically necessary and was for the treatment of a hematologic malignancy that has relapsed or is refractory AND:

  • The DLI is to prevent a relapse for those at high risk for relapse. This would include T cell depleted grafts or non-myeloablative (reduced-intensity conditioning) allogeneic HCT. OR
  • To convert an individual from mixed to full donor chimerism.

Donor lymphocyte infusion (DLI) is considered investigational following allogeneic-hematopoietic cell transplantation (HCT) that was originally considered investigational for the treatment of a hematologic malignancy.

Donor lymphocyte infusion is considered investigational as a treatment of non-hematologic malignancies following a prior allogeneic HCT.

Genetic or other modification of donor lymphocytes is considered investigational.

DESCRIPTION OF PROCEDURE OR SERVICE:

Donor lymphocyte infusion (DLI), also called donor leukocyte or buffy-coat infusion is a type of therapy in which T lymphocytes from the blood of a donor are given to an individual who has already received a hematopoietic stem cell transplant (HCT) from the same donor. The DLI therapeutic effect results from a graft-versus-leukemic or graft-versus-tumor effect due to the recognition of certain antigens on the cancer cells by the donor lymphocytes and the resultant elimination of the tumor cells.

Approximately 40-60% of individuals who receive a DLI develop graft-versus-host disease (GVHD), and the development of GVHD predicts a response to the DLI. Treatment-related mortality after DLI is 5-20%. There does not seem to be a correlation between the type of hematologic malignancy for which the DLI was given and the development of GVHD. The risk of development of GVHD is related, in part, to DLI dose and therapy before DLI.

DLI may be used for various indications such as relapse after an allogeneic HCT, as a planned strategy to prevent disease relapse in the setting of T cell depleted grafts or non-myeloablative conditioning regimens, or as a method to convert mixed to full donor chimerism. Management of relapse, which occurs in approximately 40% of all hematologic malignancy individuals, is the most common indication for DLI.

The literature is heterogeneous for reporting methods of cell collection, indication (e.g., after chemotherapy, in early relapse); cell dose infused and cell subtype used. In addition, many studies include multiple diseases with little information regarding disease-specific outcomes; however, DLI is used in nearly all hematologic malignancies for which allogeneic HCT is performed, including chronic myeloid leukemia (CML), acute myeloid and lymphoblastic leukemias, myelodysplastic syndromes, multiple myeloma and Hodgkin’s (HL) and non-Hodgkin’s lymphoma (NHL).

KEY POINTS:

The most recent literature review was performed through March 8, 2024.

Summary of Evidence

For individuals who have been treated with an allogeneic HCT who receive DLI, the evidence includes non randomized comparative studies and case series. Relevant outcomes are overall survival and change in disease status. In various hematologic malignancies and for various indications such as planned or preemptive DLI, treatment of relapse, or conversion of mixed to full donor chimerism, individuals have shown evidence of response to DLI. The response rates to DLI for relapsed hematologic malignancies following an allogeneic HCT are best in CML, followed by lymphomas, multiple myeloma and acute leukemias, respectively. Other than CML, clinical responses are most effective when chemotherapy induction is used to reduce the tumor burden before DLI. Based on comparison to the natural history of relapsed hematologic malignancy, the evidence is sufficient to determine qualitatively that the technology results in a meaningful improvement in the net health outcome.

For individuals who have been treated with an allogeneic HCT who receive modified (genetic or other ex vivo modification) donor lymphocytes infusion, the evidence includes case series. Relevant outcomes are overall survival and change in disease status. The case series demonstrate the feasibility of the technique and no serious adverse effects. Without a comparison to standard treatment, the efficacy of administering modified donor lymphocytes is unknown. The evidence is insufficient to determine the effects of the technology on health outcomes.

Practice Guidelines and Position Statements

National Comprehensive Cancer Network

National Comprehensive Cancer Network (NCCN) recommendations for treating CML (v2.2024) state that DLI is effective in inducing durable molecular remissions in the majority of individuals with relapsed CML following allogeneic HCT, though it is more effective in individuals with chronic phase relapse than advanced phase relapse.

NCCN guidelines references a study that suggests that azacitidine followed by donor lymphocyte infusions (DLIs) may be a treatment option for therapy in individuals who have AML that relapses after allogeneic HCT (v1.2024).

NCCN recommendations for treating acute lymphoblastic leukemia (v4.2023) state that DLI can be considered an option for patients in relapse after allogeneic HCT (category 2A).

NCCN guidelines do not include the use of DLI in the treatment of non-Hodgkin lymphoma or Hodgkin lymphoma (v2.2024).

NCCN recommendations for treating multiple myeloma (v2.2024) state that DLI can be considered an option for individuals who do not respond or are in relapse after allogeneic HCT (category 2A).

U.S. Preventive Services Task Force Recommendations

Not Applicable.

This medical policy is not an authorization, certification, explanation of benefits, or a contract. Eligibility and benefits are determined on a case-by-case basis according to the terms of the member’s plan in effect as of the date services are rendered. All medical policies are based on (i) research of current medical literature and (ii) review of common medical practices in the treatment and diagnosis of disease as of the date hereof. Physicians and other providers are solely responsible for all aspects of medical care and treatment, including the type, quality, and levels of care and treatment.

This policy is intended to be used for adjudication of claims (including pre-admission certification, pre-determinations, and pre-procedure review) in Blue Cross and Blue Shield’s administration of plan contracts.

The plan does not approve or deny procedures, services, testing, or equipment for our members. Our decisions concern coverage only. The decision of whether or not to have a certain test, treatment or procedure is one made between the physician and his/her patient. The plan administers benefits based on the member’s contract and corporate medical policies. Physicians should always exercise their best medical judgment in providing the care they feel is most appropriate for their patients. Needed care should not be delayed or refused because of a coverage determination.

As a general rule, benefits are payable under health plans only in cases of medical necessity and only if services or supplies are not investigational, provided the customer group contracts have such coverage.

The following Association Technology Evaluation Criteria must be met for a service/supply to be considered for coverage:

1. The technology must have final approval from the appropriate government regulatory bodies;

2. The scientific evidence must permit conclusions concerning the effect of the technology on health outcomes;

3. The technology must improve the net health outcome;

4. The technology must be as beneficial as any established alternatives;

5. The improvement must be attainable outside the investigational setting.

Medical Necessity means that health care services (e.g., procedures, treatments, supplies, devices, equipment, facilities or drugs) that a physician, exercising prudent clinical judgment, would provide to a patient for the purpose of preventing, evaluating, diagnosing or treating an illness, injury or disease or its symptoms, and that are:

1. In accordance with generally accepted standards of medical practice; and

2. Clinically appropriate in terms of type, frequency, extent, site and duration and considered effective for the patient’s illness, injury or disease; and

3. Not primarily for the convenience of the patient, physician or other health care provider; and

4. Not more costly than an alternative service or sequence of services at least as likely to produce equivalent therapeutic or diagnostic results as to the diagnosis or treatment of that patient’s illness, injury or disease.
