_______________________________________________________________________________________

IMPORTANT NOTE:

The purpose of this policy is to provide general information applicable to the administration of health benefits that Horizon Blue Cross Blue Shield of New Jersey and Horizon Healthcare of New Jersey, Inc. (collectively “Horizon BCBSNJ”) insures or administers. If the member’s contract benefits differ from the medical policy, the contract prevails. Although a service, supply or procedure may be medically necessary, it may be subject to limitations and/or exclusions under a member’s benefit plan. If a service, supply or procedure is not covered and the member proceeds to obtain the service, supply or procedure, the member may be responsible for the cost. Decisions regarding treatment and treatment plans are the responsibility of the physician. This policy is not intended to direct the course of clinical care a physician provides to a member, and it does not replace a physician’s independent professional clinical judgment or duty to exercise special knowledge and skill in the treatment of Horizon BCBSNJ members. Horizon BCBSNJ is not responsible for, does not provide, and does not hold itself out as a provider of medical care. The physician remains responsible for the quality and type of health care services provided to a Horizon BCBSNJ member.

Horizon BCBSNJ medical policies do not constitute medical advice, authorization, certification, approval, explanation of benefits, offer of coverage, contract or guarantee of payment.

Interleukin-2 (IL-2) is a protein that is naturally produced by lymphocytes (CD4 T-cells). It is an important regulator of the immune system, with potent effects on T cells, B cells, and natural killer (NK) cells.

Recombinant IL-2 is commercially available as Proleukin (aldesleukin) and is produced by recombinant DNA technology involving Escherichia coli containing the human gene that codes for IL-2. The resultant purified protein has the same biological activity as native human IL-2.

[INFORMATIONAL NOTE: The FDA-approved Proleukin (aldesleukin) package insert has the following BLACK BOX WARNINGS:
  • Therapy should be restricted to patients with normal cardiac and pulmonary functions as defined by thallium stress testing and formal pulmonary function testing. Extreme caution should be used in patients with a normal thallium stress test and a normal pulmonary function test who have a history of cardiac or pulmonary disease.
  • This agent should be administered in a hospital setting under the supervision of a qualified physician experienced in the use of anticancer agents. An intensive care facility and specialists skilled in cardiopulmonary or intensive care medicine must be available.
  • The administration of this medication has been associated with capillary leak syndrome (CLS) which is characterized by a loss of vascular tone and extravasation of plasma proteins and fluid into the extravascular space. CLS results in hypotension and reduced organ perfusion which may be severe and can result in death. CLS may be associated with cardiac arrhythmias (supraventricular and ventricular), angina, myocardial infarction, respiratory insufficiency requiring intubation, gastrointestinal bleeding or infarction, renal insufficiency, edema, and mental status changes.
  • This treatment is associated with impaired neutrophil function (reduced chemotaxis) and with an increased risk of disseminated infection, including sepsis and bacterial endocarditis. Consequently, preexisting bacterial infections should be adequately treated prior to initiation of PROLEUKIN therapy. Patients with indwelling central lines are particularly at risk for infection with gram positive microorganisms. Antibiotic prophylaxis with oxacillin, nafcillin, ciprofloxacin, or vancomycin has been associated with a reduced incidence of staphylococcal infections.
  • The administration of this drug should be withheld in patients developing moderate to severe lethargy or somnolence; continued administration may result in coma.]

Policy:
(Note: For Medicare Advantage, please refer to the Medicare Coverage Section below for coverage guidance.)

1. Recombinant interleukin-2 (IL-2) is considered medically necessary for adult members with the following FDA indications when the criteria below are met:

    • Treatment of metastatic renal cell carcinoma OR treatment of metastatic melanoma (documentation of medical records required); AND
    • The prescriber is a specialist in the area of the patient’s diagnosis (e.g. oncologist) or has consulted with a specialist in the area of the patient’s diagnosis; AND
    • Prior to starting therapy, all of the following:
      • Normal results from thallium stress test for cardiac function (documentation of medical records required)
      • Normal pulmonary function tests (documentation of medical records required)
      • Absence of organ allograft
      • ECOG performance score of 0-1 (documentation of medical records required)

    [INFORMATIONAL NOTE: As per the FDA-approved package insert (PI), each course of treatment consists of two 5-day treatment cycles separated by a rest period. It is recommended to administer 600,000 International Units/kg (0.037 mg/kg) dose administered by a 15-minute IV infusion every 8 hours, for a maximum of 14 doses. Following 9 days of rest, the schedule is repeated for another 14 doses, for a maximum of 28 doses per course, as tolerated. Each course of treatment consists of two 5-day treatment cycles separated by a rest period. Patients should be evaluated for response approximately 4 weeks after completion of a course of therapy and again immediately prior to the scheduled start of the next treatment course. Additional courses of treatment should be given to patients only if there is some tumor shrinkage following the last course and retreatment is not contraindicated.]
      Proleukin is contraindicated in patients with an abnormal thallium stress test or abnormal pulmonary function tests and those with organ allografts. Retreatment with Proleukin is contraindicated in patients who have experienced the following drug-related toxicities while receiving an earlier course of therapy: sustained ventricular tachycardia (≥5 beats), cardiac arrhythmias not controlled or unresponsive to management, chest pain with ECG changes, consistent with angina or myocardial infarction, Cardiac tamponade, intubation for >72 hours, renal failure requiring dialysis >72 hours, coma or toxic psychosis lasting >48 hours, repetitive or difficult to control seizures, bowel ischemia/perforation, GI bleeding requiring surgery.]
      2. Recombinant interleukin-2 (IL-2) is considered medically necessary for the following off-label uses:
        • Melanoma
          • High dose single-agent therapy for metastatic or unresectable disease as second line or subsequent therapy for disease progression or after maximum clinical benefit from BRAF targeted therapy
          • High-dose interleukin-2 should not be used for patients with inadequate organ reserve, poor performance status, or untreated or active brain metastases.
        • Kidney cancer
          • First-line therapy as a high-dose single agent for selected patients (excellent performance status and normal organ function) with relapsed or medically unresectable stage IV disease with predominant clear cell histology
        • Hematopoietic Cell Transplantation
          • For chronic graft-versus-host disease (GVHD) as additional therapy in conjunction with systemic corticosteroids following no response (steroid-refractory disease) to first-line therapy options
      3. IL-2 is considered investigational including, but not limited to, the following conditions:
        • Therapy to maintain remission after high-dose chemotherapy for a variety of malignancies (e.g., lung cancer, colorectal cancer, bladder cancer, neuroblastoma, pancreatic cancer, endometriomas, etc.) and pre-malignancies (e.g., myelodysplastic syndromes).
        • Management of human immunodeficiency virus (HIV) infection, and juvenile rheumatoid arthritis

      [INFORMATIONAL NOTE: The randomized open label study which served as the basis of this off-label use of IL-2 in patients with HIV suggested that intermittent therapy with IL-2 and highly active antiretroviral therapy (HAART) produced a substantially greater increase in CD4 cell counts. The study showed doses of 4.5 to 7.5 MIU twice a day for five consecutive days every 8 weeks are effective in increasing CD4 count without adversely affecting viral load.]

      Medicare Coverage

      There is no National Coverage Determination (NCD) or Local Coverage Determination (LCD) for jurisdiction JL for this service. Therefore, Medicare Advantage Products will follow the Horizon BCBSNJ medical policy.

      Horizon BCBSNJ Medical Policy Development Process:

      This Horizon BCBSNJ Medical Policy (the “Medical Policy”) has been developed by Horizon BCBSNJ’s Medical Policy Committee (the “Committee”) consistent with generally accepted standards of medical practice, and reflects Horizon BCBSNJ’s view of the subject health care services, supplies or procedures, and in what circumstances they are deemed to be medically necessary or experimental/ investigational in nature. This Medical Policy also considers whether and to what degree the subject health care services, supplies or procedures are clinically appropriate, in terms of type, frequency, extent, site and duration and if they are considered effective for the illnesses, injuries or diseases discussed. Where relevant, this Medical Policy considers whether the subject health care services, supplies or procedures are being requested primarily for the convenience of the covered person or the health care provider. It may also consider whether the services, supplies or procedures are more costly than an alternative service or sequence of services, supplies or procedures that are at least as likely to produce equivalent therapeutic or diagnostic results as to the diagnosis or treatment of the relevant illness, injury or disease. In reaching its conclusion regarding what it considers to be the generally accepted standards of medical practice, the Committee reviews and considers the following: all credible scientific evidence published in peer-reviewed medical literature generally recognized by the relevant medical community, physician and health care provider specialty society recommendations, the views of physicians and health care providers practicing in relevant clinical areas (including, but not limited to, the prevailing opinion within the appropriate specialty) and any other relevant factor as determined by applicable State and Federal laws and regulations.
