What is IDA?

IDA is the most common type of anemia1

commonAnemia1

Iron helps produce hemoglobin, a part of red blood cells, which is a molecule that carries oxygen in your blood.1

commonAnemia2

Without enough iron, your body starts using the iron it has stored. Soon, the stored iron gets used up.1

commonAnemia3

Without iron, your body cannot produce the number of normal red blood cells needed to keep you in good health.2

What causes IDA?

  • Low iron levels (iron deficiency) cause IDA1
  • IDA occurs when iron in your body becomes depleted or you aren’t adequately replenishing what your body uses1
  • Your iron deficiency is the difference between the amount of iron you have and the amount you need to keep you in good health3,4
  • If your iron deficiency progresses, you may have IDA4

IDA can coexist with many different diseases or conditions

  • IDA and gastrointestinal conditions

IDA lab markers

Common lab markers for monitoring IDA and normal iron levels in adults

microscope

Your lab results are the results of your blood test. They are used to diagnose iron deficiency anemia (IDA) and monitor and manage your condition during treatment.

Chart
Chart
Hb, hemoglobin; TSAT, transferrin saturation.

An additional test for total iron binding capacity (TIBC) may be required to diagnose IDA. Normal values for TIBC range from 240 to 450 μg/dL in healthy patients.6,7 Please note TIBC values were not measured in Injectafer clinical trials.

*Injectafer has not been studied or approved for treating people with chronic kidney disease (CKD) who are on dialysis or people with anemia of chronic disease. For patients with CKD and anemia, guidelines issued by the National Kidney Foundation (NKF) define TSAT of 30% as a lower limit to begin treatment. Please consult the NKF guidelines for a complete list of recommendations for IDA lab values when starting treatment.8,9

Your doctor will most likely prescribe an oral iron treatment for you first.

For some people with IDA, iron pills may not be the right option. There are several reasons why this might be. The most common reasons are1,2:

  • Iron in oral form can cause hard-to-tolerate side effects
  • Oral iron can fail to replenish iron levels to where the body needs them because the digestive system has trouble absorbing it

EVEN IN HEALTHY PATIENTS, LESS THAN 10% OF ORAL IRON IS ABSORBED3*

*Less than 10% absorption of oral iron is based on a regimen of 300-mg or 320-mg tablets 3 to 4 times a day.4

Patients with IDA may require IV iron therapy. This kind of treatment is done in an infusion center.

Some of the reasons your doctor may prescribe IV iron to treat your IDA could include:

  • Oral iron is not absorbing well in the digestive system
  • Blood loss—which can be caused by a number of things including, but not limited to, heavy periods, major surgery or physical trauma, and some gastrointestinal diseases

Injectafer: An IV iron

  • Injectafer is used to treat adults and pediatric patients 1 year of age and older with iron deficiency anemia5:
    • When oral iron treatments haven't worked, or side effects from oral iron couldn't be tolerated, or
    • For adults with non-dialysis dependent chronic kidney disease
  • Unlike with pills, 100% of the iron in Injectafer goes directly into the bloodstream5
  • Proven in clinical studies in more than 8800 patients, Injectafer demonstrated greater increases in hemoglobin at follow-up than either oral iron or another intravenous (IV) iron6,7

Injectafer provides the most iron per course of treatment—up to 1500 mg in 2 doses of 750 mg separated by at least 7 days.5,8-12† Injectafer is also available as a 100 mg iron/2 mL single-dose vial.5

Slow IV push over 7.5 minutes

Injectafer treatment may be repeated if IDA reoccurs. Monitor serum phosphate levels in patients at risk for low serum phosphate who require a repeat course of treatment.5

Compared to the dosing regimens of other IV iron treatments.5,8-12 For patients weighing less than 50 kg (110 lb), give each dose as 15 mg/ kg body weight for a total cumulative dose not to exceed 1500 mg of iron per course of treatment.1

§When administered via IV infusion, dilute up to 750 mg of iron in no more than 250 mL of sterile 0.9% sodium chloride injection, USP, such that the concentration of the infusion is not <2 mg of iron per mL, and administer over at least 15 minutes. When administered as a slow IV push, give at the rate of approximately 100 mg (2 mL) per minute.5

  • Potential side effects with Injectafer include, but are not limited to, allergic reactions, nausea, temporary hypertension, and flushing5

    If you weigh less than 110 pounds, you may be given a smaller amount of Injectafer. Your doctor will decide on the most appropriate way to give you your treatment5:
  • Each Injectafer infusion takes about 15 minutes. After your infusion, your healthcare provider will monitor you for signs and symptoms of an allergic reaction—usually for about 30 minutes
  • If you are at risk for low serum phosphate, your doctor may monitor your serum phosphate levels if you require a second course of treatment of Injectafer (beyond 2 administrations of up to 750 mg each). Your doctor can discuss risk factors for low serum phosphate with you

Over 2 million people have been treated with Injectafer in the United States alone.7 II

Preparing for Injectafer infusions

Injectafer is given by IV infusion, usually at an infusion center, where a healthcare professional can administer it directly into the bloodstream through a vein. Infusion centers are medical facilities equipped and staffed for administering infusions.1

How long do Injectafer infusions take?

stopwatch
  • Each Injectafer infusion may take about 15 minutes2
  • Afterward, your healthcare provider will monitor you for about 30 minutes for signs of allergic reaction2
  • Before your first Injectafer infusion

    • Call ahead to confirm that the infusion center can provide Injectafer IV iron
    • Ask about Injectafer by name. Injectafer is the only FDA-approved IV iron that can provide up to 1500 mg of iron in just 2 doses of 750 mg separated by at least 7 days2
    • Dress comfortably and eat as you normally would. There are no special dietary requirements
    • Bring insurance coverage identification and any other information your doctor has asked you to bring
  • During your infusion

    • The usual dosage is 1500 mg, administered in 2 separate doses of 750 mg each separated by at least 7 days. Your dosage may vary based on your weight2
    • Your infusion may take about 15 minutes, and your doctor or nurse will monitor your response during and after your infusion2
  • After each infusion

    • Your iron stores are replenished over time, so it’s important for you to follow up with your doctor and retest your levels3
    • In some patients, an increase in blood pressure with dizziness, nausea, or flushing of the face may occur right after a dose of Injectafer. It usually goes away within 30 minutes. Tell your doctor right away if symptoms persist or worsen2
    • Be sure to follow up with your physician to see how Injectafer is working for you

  • IMPORTANT SAFETY INFORMATION


    INDICATIONS

    Injectafer® (ferric carboxymaltose injection) is indicated for the treatment of iron deficiency anemia (IDA) in adult and pediatric patients 1 year of age and older who have either intolerance to oral iron or an unsatisfactory response to oral iron, or adult patients who have non-dialysis dependent chronic kidney disease.

    IMPORTANT SAFETY INFORMATION

    CONTRAINDICATIONS

    Injectafer is contraindicated in patients with hypersensitivity to Injectafer or any of its inactive components.

    WARNINGS AND PRECAUTIONS

    Symptomatic hypophosphatemia requiring clinical intervention has been reported in patients at risk of low serum phosphate in the postmarketing setting. These cases have occurred mostly after repeated exposure to Injectafer in patients with no reported history of renal impairment. Possible risk factors for hypophosphatemia include a history of gastrointestinal disorders associated with malabsorption of fat- soluble vitamins or phosphate, concurrent or prior use of medications that affect proximal renal tubular function, hyperparathyroidism, vitamin D deficiency and malnutrition. In most cases, hypophosphatemia resolved within three months.

    Monitor serum phosphate levels in patients at risk for low serum phosphate who require a repeat course of treatment.

    Serious hypersensitivity reactions, including anaphylactic-type reactions, some of which have been life- threatening and fatal, have been reported in patients receiving Injectafer. Patients may present with shock, clinically significant hypotension, loss of consciousness, and/or collapse. Monitor patients for signs and symptoms of hypersensitivity during and after Injectafer administration for at least 30 minutes and until clinically stable following completion of the infusion. Only administer Injectafer when personnel and therapies are immediately available for the treatment of serious hypersensitivity reactions. In clinical trials, serious anaphylactic/anaphylactoid reactions were reported in 0.1% (2/1775) of subjects receiving Injectafer. Other serious or severe adverse reactions potentially associated with hypersensitivity which included, but were not limited to, pruritus, rash, urticaria, wheezing, or hypotension were reported in 1.5% (26/1775) of these subjects.

    In clinical studies, hypertension was reported in 4% (67/1775) of subjects in clinical trials 1 and 2. Transient elevations in systolic blood pressure, sometimes occurring with facial flushing, dizziness, or nausea were observed in 6% (106/1775) of subjects in these two clinical trials. These elevations generally occurred immediately after dosing and resolved within 30 minutes. Monitor patients for signs and symptoms of hypertension following each Injectafer administration.

    In the 24 hours following administration of Injectafer, laboratory assays may overestimate serum iron and transferrin bound iron by also measuring the iron in Injectafer.

    ADVERSE REACTIONS

    Adults

    In two randomized clinical studies [Studies 1 and 2], a total of 1775 patients were exposed to Injectafer, 15 mg/kg of body weight, up to a maximum single dose of 750 mg of iron on two occasions, separated by at least 7 days, up to a cumulative dose of 1500 mg of iron. Adverse reactions reported by >2% of Injectafer-treated patients were nausea (7.2%); hypertension (4%); flushing (4%); injection site reactions (3%); erythema (3%); hypophosphatemia (2.1%); and dizziness (2.1%).

    The following adverse reactions have been identified during post approval use of Injectafer. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

    The following adverse reactions have been reported from the post-marketing spontaneous reports with Injectafer: cardiac disorders: tachycardia; general disorders and administration site conditions: chest discomfort, chills, pyrexia; metabolism and nutrition disorders: hypophosphatemia; musculoskeletal and connective tissue disorders: arthralgia, back pain, hypophosphatemic osteomalacia (rarely reported event); nervous system disorders: syncope; respiratory, thoracic and mediastinal disorders: dyspnea; skin and subcutaneous tissue disorders: angioedema, erythema, pruritus, urticaria; pregnancy: fetal bradycardia.

    Pediatric

    The safety of Injectafer in pediatric patients was evaluated in Study 3. Study 3 was a randomized, active-controlled study in which 40 patients (1 to 12 years of age: 10 patients, 12 to 17 years of age: 30 patients) received Injectafer 15 mg/kg to a maximum single dose of 750 mg (whichever was smaller) on Days 0 and 7 for a maximum total dose of 1500 mg; 38 patients evaluable for safety in the control arm received an age-dependent formulation of oral ferrous sulfate for 28 days. The median age of patients who received Injectafer was 14.5 years (range, 1-17); 83% were female; 88% White and 13% Black. The most common adverse reactions (≥4%) were hypophosphatemia, injection site reactions, rash, headache, and vomiting.

    CLINICAL CONSIDERATIONS IN PREGNANCY

    Untreated IDA in pregnancy is associated with adverse maternal outcomes such as postpartum anemia. Adverse pregnancy outcomes associated with IDA include increased risk for preterm delivery and low birth weight.

    Severe adverse reactions including circulatory failure (severe hypotension, shock including in the context of anaphylactic reaction) may occur in pregnant women with parenteral iron products (such as Injectafer) which may cause fetal bradycardia, especially during the second and third trimester.

The most common adverse reactions (≥4%) were hypophosphatemia, injection site reactions, rash, headache, and vomiting.

CLINICAL CONSIDERATIONS IN PREGNANCY

Untreated IDA in pregnancy is associated with adverse maternal outcomes such as postpartum anemia. Adverse pregnancy outcomes associated with IDA include increased risk for preterm delivery and low birth weight.

Severe adverse reactions including circulatory failure (severe hypotension, shock including in the context of anaphylactic reaction) may occur in pregnant women with parenteral iron products (such as Injectafer) which may cause fetal bradycardia, especially during the second and third trimester.
