  Iron Therapy, Parenteral

Description:
Parenteral iron therapy is indicated in individuals with iron deficiency anemia associated with conditions that interfere with the ingestion or absorption of oral iron. Failure to respond to oral iron therapy does not automatically recommend parenteral iron therapy.

Policy/
Coverage:
The following iron preparations are non-covered. See statements of non-coverage below.
 
Ferric derisomaltose (e.g., Monoferric)
Ferric carboxymaltose (e.g., Injectafer)
 
The Step Therapy Medication Act is applicable to fully insured (Arkansas Blue Cross, Health Advantage, and Exchange) and specified governmental (ASE/PSE and ASP) health plans. The law is not applicable to FEP or self-insured ERISA groups (including but not limited to Walmart or other Blue Advantage groups). Initial approval for exigent request is 28 days. Otherwise, initial approval for standard review is up to 1 year.

For members with contracts without primary coverage criteria, the use of ferric carboxymaltose (Injectafer) as parenteral iron therapy for any indication is considered not medically necessary.

Rationale:
The majority of patients are able to tolerate oral iron therapy without difficulty.  Perhaps 10-20% of patients may have symptoms, usually gastrointestinal, attributable to oral iron.  Parenteral iron therapy, with the risk of adverse reactions, should be reserved for the exceptional patient who remains intolerant of oral iron therapy despite repeated modifications in the dosing regimen.
 
A screening test for iron malabsorption is the administration to the fasting patient of 100 mg of elemental iron as ferrous sulfate in a liquid preparation, followed by measurements of plasma iron concentrations 1 and then 2 hours later. In an iron-deficient patient with an initial plasma iron concentration less than 50 mg/dL, an increase in plasma iron concentration of 200 to 300 mg/dL is expected. An increase in plasma iron concentration less than 100 mg/dL suggests malabsorption and is an indication for a small-bowel biopsy (Cook & Hoffman).
 
There is a theory that inflammatory cytokines (tumor necrosis factor, interleukin, interferon) create a block in iron delivery from the reticuloendothelial system. There is one randomized controlled trial that addresses the question of whether patients with anemia associated with malignancy, but with apparent normal iron stores, benefit from the administration of intravenous iron along with administration of epoetin.  A randomized controlled trial (Auerbach, 2004) compared patients treated with no iron, IV iron, and oral iron, and although each group showed improvement in hemoglobin level, the group receiving IV iron improved the most.  There also has been criticism of the methodology of this paper, and subsequent reviews of this subject have stated that more investigation of is needed; in addition, the paper was sponsored by the manufacturer of an IV iron preparation, and neither the patients nor the investigators were not blinded to the therapy.  
 
A prospective,  randomized, controlled, open labeled, multicenter trial (Henry, 2007) compared epoetin alfa with either no iron, oral iron or IV iron over an eight week period.  This studied should an increase in mean Hb in all groups thought the IV iron group showed the greatest increase.  Several criticisms of this paper include the short iron treatment time (8 weeks as compared to 12 weeks) which may have be insufficient time for oral iron improvements to b e detected.  Also, there was a significant difference in patient s assigned to the IV iron group and oral iron group.  The IV iron group had a greater number of breast cancer patients while the oral iron group had a greater number of colorectal cancers.  Those with colorectal cancer would be more likely to have iron deficiency than would patients with breast cancer.  The study also included patients with normal iron stores.  This study was sponsored by the company that supplied the IV iron and several authors were paid consultants for the sponsoring company.  Neither investigators nor patients were blinded to the therapy.
 
The 2007 edition of AHFS Drug Compendia had the following information and is unchanged in the 2010 edition:
“There are relatively few indications for parenteral iron therapy.  Occasionally, however, parenteral administration may be required in iron-deficient patients in whom oral administration of iron is infeasible or ineffective because of intolerance, poor absorption, GI disease, refusal or inability to take the oral medication, or when rapid replenishment of iron stores is necessary as in hypochromic anemia of infancy or the last trimester of pregnancy.  In addition, most chronic renal failure patients who received therapy with epoetin alfa will require oral or parenteral iron therapy because of the dramatic decrease in iron stores associated with erythrocyte formation.  
 
“Since parenteral use of complexes of iron and carbohydrates has resulted in fatal anaphylactoid reactions, iron dextran should be used only in patients in whom a clearly established indication for parenteral iron therapy exists, confirmed by appropriate laboratory tests." (Italics, original).
 
“The hematologic response to parenterally administered iron dextran is no more rapid than to orally administered iron salts in patients in whom oral iron is effective.  The response to iron dextran is also quantitatively similar to that produced by other iron preparations administered parenterally.”
 
2012 Update
This policy is being updated after a review of the relevant published literature identified in a search of the MEDLINE database. A randomized, double-blind, placebo-controlled study to investigate the effect of parenteral iron to treat fatigue in nonanemic patients was identified (Krayenbuehl, 2011). In this study, 90 premenopausal women, presenting with fatigue with serum ferritin less than or equal to 50ng/ml and hemoglobin greater than or equal to 120 g/L were randomized to receive intravenous iron or placebo. The authors report that after 6 weeks, fatigue decreased in the group treated with iron by 1.1 compared with 0.7 in those treated with placebo (P=.07). In patients with serum ferritin less than 5ng/ml, fatigue decreased by 1.8 in the iron group compared with 0.4 in the placebo group (p=.005). In an accompanying editorial, Drygalski and Adamson conclude, “Given the numbers of women who are iron deficient, the findings could find broad application, but work needs to be done to refine the approach to this common problem” (Drygalski, 2011). According to Drygalski and Adamson, this study raises several questions including the dosage of iron needed to see these effects as well as the route of administration (parenteral versus oral). Further studies are needed to answer these and other questions regarding the use of parenteral iron in the treatment of fatigue in nonanemic patients.
 
2013 Update
The policy is updated with a literature search through May 2013. The coverage statement has been revised to include separate ferritin requirements for adults, children and pregnant women; individuals with active inflammatory states (e.g. rheumatoid arthritis, inflammatory bowel disease); and individuals with end-stage renal disease/chronic renal failure.
