Interferons are used for a variety of medical problems. They are approved for benefits for some diagnoses.

 

Preauthorization may be required.

 

PEGylated interferon alpha 2B (Peg Intron) is not covered for the treatment of Hepatitis C.  Pegasys (PEGylated interferon alpha 2A) should be used instead.

 

Interferons are considered specialty medications and are covered under the specialty drug benefit.  Most products are covered under the pharmacy benefit.

Medical Statement

I.  Interferon Alpha

Interferon Alpha is considered medically necessary for the following indications:

1)    AIDS-associated Kaposi`s sarcoma;

2)    Basal cell carcinoma, when surgical intervention is contraindicated (interferon therapy in basal cell carcinoma is only considered medically necessary for those persons in which surgical intervention is contraindicated; surgical intervention is considered first-line therapy for basal cell carcinoma, and has been shown to have a 95% treatment success rate);

3)    Carcinoid syndrome;

4)    Cervical carcinoma, in persons who cannot tolerate, or whose tumor is resistant to, standard first-line therapy;

5)    Chronic myelogenous leukemia;

6)    Colorectal carcinoma, when used in conjunction with 5-FU;

7)    Condylomata Acuminata (genital warts) (intralesional only);

8)    Cutaneous T-cell lymphoma (including mycosis fungoides);

9)    Desmoids tumors (fibromatosis), for unresectable disease or gross residual disease following surgery;

10)   Essential Thrombocythemia;

11)   Hairy cell leukemia;

12)   Hepatitis C (non-A, non-B hepatitis), in persons with compensated liver disease (Child-Pugh score less than or equal to 6 [class A]) (the safety and efficacy have not been established for treatment of persons with decompensated liver disease). Continued treatment with interferon alpha is considered not medically necessary for persons with HCV genotypes 1 and 4 through 6 who have failed to attain an early virologic response after 12 weeks of treatment (where early virologic response is indicated by achievement of at least a 100-fold (2 log10) decrease in serum HCV from pretreatment baseline). Up to a maximum of 24 weeks of interferon alpha is considered medically necessary for persons with HCV genotypes 2, 3, and 7 through 10; and up to a maximum of 48 weeks of interferon alpha is considered medically necessary for persons with HCV genotypes 1 and 4 through 6. A course of standard interferon alpha in persons with hepatitis C who have failed to respond or relapsed after an adequate course of PEGylated interferon alpha or consensus interferon is considered experimental and investigational because of a lack of evidence on the effectiveness of standard interferon in these persons. Note: Upon medical review, extended treatment with interferon alpha beyond these limits may be considered medically necessary for persons with cryoglobulinemia and for liver transplant recipients with recurrent hepatitis C infection;

13)   Hepatocellular carcinoma, for persons with hepatitis C and completely resected tumors;

14)   Hyper-eosinophilic syndrome that is not adequately responsive to glucocorticoids;

15)   Kasabach-Merritt syndrome;

16)   Life-threatening hemangioma of infancy (intralesional) when member is intolerant of, or the hemangioma is resistant to, corticosteroid therapy;

17)   Malignant melanoma;

18)   Meningioma, recurrent, surgically inaccessible; 

19)   Malignant mesothelioma in persons who have relapsed following surgery and failed treatment with or cannot tolerate first-line chemotherapy;

20)   Multiple myeloma, solitary plasmacytoma, or systemic light chain amyloidosis;

21)   non-Hodgkin`s lymphoma (including adult T-cell lymphoma (chronic, smoldering or acute) and mycosis fungoides/Sezary syndrome);

22)   Ocular herpes simplex (interferon alpha eye drops);

23)   Ovarian carcinoma, in persons who cannot tolerate, or whose tumor is resistant to, standard first-line therapy;

24)   Pancreatic islet cell carcinoma;

25)   Persons with chronic hepatitis B who meet all of the following criteria:

a.  Member has compensated liver disease (Child-Pugh score less than or equal to 6

[class A]); and 

b.  Serum aminotransferase (AST) greater than double the upper limit of normal range (AST normal range 0-35 u/l).

A course of standard interferon alpha in persons with hepatitis B who have failed an adequate course of PEGylated interferon alpha is considered experimental and investigational because of a lack of evidence on the effectiveness of standard interferon in these persons.

Limits

Interferon Alpha:

Continued treatment with interferon alpha is considered not medically necessary for persons with HCV genotypes 1 and 4 who have failed to attain an early virologic response after 12 weeks of treatment (where early virologic response is indicated by achievement of at least a 100-fold (2 log10) decrease in serum HCV from pretreatment baseline).

Up to a maximum of 24 weeks of interferon alpha is considered medically necessary for persons with HCV genotypes 2 and 3, and up to a maximum of 48 weeks of interferon alpha is considered medically necessary for persons with HCV genotypes 1 and 4.

Extended treatment with interferon alpha beyond these limits will be considered medically necessary for persons with cryoglobulinemia and for liver transplant recipients with recurrent hepatitis C infection.

A course of standard interferon alpha in persons with hepatitis C who have failed an adequate course of PEGylated interferon alpha is considered experimental and investigational because of a lack of evidence on the effectiveness of standard interferon in these persons.

The use of interferon alpha is considered contraindicated in the following persons with hepatitis B:

·       Those who are HIV positive;

·       Hepatitis B surface antigen (HBs Ag) positive persons undergoing liver transplantation;

·       Those with a history of or currently active autoimmune hepatitis.

A course of standard interferon alpha in persons with hepatitis B who have failed an adequate course of PEGylated interferon alpha is considered experimental and investigational because of a lack of evidence on the effectiveness of standard interferon in these persons.

Interferon alpha is considered experimental and investigational for all other indications because it has not been shown to be effective for them including:

1.          Acute hepatitis B;

2.          Age-related macular degeneration;

3.          AIDS-related complex;

4.          AIDS in combination with AZT;

5.          Breast cancer;

6.          Chickenpox;

7.          Chronic delta hepatitis;

8.          Cutaneous warts;

9.          Cytomegalovirus (CMV);

10.      Gardner syndrome;

11.      Hepatitis D;

12.      Hereditary hemorrhagic telangiectasia;

13.      Herpes keratoconjunctivitis;

14.      Herpes simplex;

15.      Keloids;

16.      Multiple sclerosis

17.      Peyronie`s disease

18.      Plexiform neurofibroma;

19.      Rhinoviruses;

20.      Vaccinia; and

21.      Varicella zoster virus (VZV).

PEGylated Interferon Alpha:

PEGylated interferon alpha 2B (Peg Intron) is not covered for treatment of Hepatitis C.

Continued treatment with PEGylated interferon alpha is considered not medically necessary for persons with HCV genotypes 1 and 4 who have failed to attain an early virologic response after 12 weeks of therapy.
Early virologic response is indicated by achievement of at least a 100-fold (2 log10) decrease in serum HCV RNA from pretreatment baseline.

For persons infected with HCV genotypes 1 and 4, up to 48 weeks of treatment with PEGylated interferons is considered medically necessary.

For persons with other HCV genotypes (i.e., genotypes 2 and 3, and genotypes 5 through 10) up to 24 weeks of treatment with PEGylated interferons are considered medically necessary.

Repeat or chronic maintenance treatment with PEGylated interferon (PEG-Intron or Pegasys) is considered not medically necessary in persons who have completed a therapeutic course of PEGylated interferon and ribavirin.

Extended treatment with PEGylated interferon alpha beyond these limits will be considered medically necessary for persons with cryglobulinemia and for liver transplant recipients with recurrent hepatitis C infections.

Treatment with peginterferon alfa-2a for more than 48 weeks is considered experimental and investigational.

Repeat or chronic maintenance treatment with peginterferon alfa-2a is considered not medically necessary in persons who have completed a therapeutic course of PEGylated interferon and ribavirin.

Extended treatment with peginterferon alfa-2a beyond these limits will be considered medically necessary for liver transplant recipients with recurrent hepatitis B infections.

PEGylated interferons are self-administered subcutaneously once weekly.

Consensus Interferon (Interferon Alfacon-1):

Use of consensus interferon for persons with hepatitis C who fail to respond to standard alpha interferon or PEGylated interferons is considered experimental and investigational. Current guidelines indicate PEGylated interferons as the treatment of choice for persons with hepatitis C, including those who fail to respond to standard alpha interferon therapy.
There is insufficient evidence in the peer-reviewed published medical literature comparing consensus interferon to PEGylated interferons, and of the effectiveness of consensus interferon in persons with hepatitis C who have failed PEGylated interferon therapy.

 

Interferon Beta:

Because interferon beta is administered subcutaneously or intramuscularly, it is appropriate for administration by the member in the home setting.

The Biojector 2000 (Bioject, Inc.) is a needle-free injection system that uses CO2 as the power source and disposable needle-free syringes to deliver medication in a fraction of a second through a tiny orifice. Biojector 2000 is considered an acceptable alternative to conventional needle and syringes for members with exacerbating-remitting MS who cannot safely use needles for self-injection due to tremors and decreased coordination.

Interferon Gamma:

Interferon gamma is considered experimental and investigational for the treatment of malignant neoplasm of peritoneum.
