Brief Summary:
To evaluate the efficacy and safety of intravenous (IV) ferumoxytol compared with placebo for the treatment of iron deficiency anemia (IDA).

Condition or disease Intervention/treatment Phase
Iron Deficiency Anemia Drug: Ferumoxytol Other: Placebo Phase 3

Detailed Description:
This Phase III, randomized, double-blind, placebo-controlled, multicenter clinical study evaluated the safety and efficacy of ferumoxytol compared with placebo for the treatment of IDA, specifically in adult patients with IDA who have a history of unsatisfactory oral iron therapy or in whom oral iron could not be used. The effect of ferumoxytol on hemoglobin, iron parameters and patient reported outcomes (PROs) compared with placebo was evaluated. Investigators were blinded to key laboratory parameters that could potentially unblind the treatment arms of the study, eg, hemoglobin [Hgb], hematocrit [Hct], iron, ferritin, total iron binding capacity [TIBC], and transferrin saturation [TSAT], and neither the Investigators nor the subjects were aware of their treatment assignment, hemoglobin or other laboratory values.

Arm Intervention/treatment
Experimental: Ferumoxytol
Participants received a total of 2 doses of IV ferumoxytol 510 milligrams (mg) (17 milliliters [mL]). The first IV 510 mg dose was administered on Day 1 (Baseline) and second dose 2 to 8 (5±3) days after the first dose, for a total cumulative dose of 1.02 grams (g).
 Drug: Ferumoxytol
IV Ferumoxytol
Other Name: Feraheme
Placebo Comparator: Placebo
Participants received a total of 2 doses of IV saline (17 mL). The first IV dose was administered on Day 1 (Baseline) and second dose 2 to 8 (5±3) days after the first dose.
 Other: Placebo
IV Placebo


Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Participants Who Achieved A ≥2.0 g/dL Increase In Hemoglobin At Any Time From Baseline To Week 5 [ Time Frame: Baseline (Day 1) through Week 5 ]

    Participants who achieved a ≥2.0 g/dL increase in hemoglobin at any time from Baseline up to Week 5 are presented. Increase in hemoglobin at any time from Baseline up to Week 5 was calculated for each participant based on:

    Hemoglobin Change = Hemoglobin (Week X) - Hemoglobin (Baseline), where Week X was any post-Baseline visit up to and including Week 5.

    Baseline was defined as the Day 1 value (prior to injection of study drug). The screening or most recent value prior to Day 1 was used for any participant with missing Day 1 information. Participants with no post-Baseline hemoglobin values were classified as not achieving a ≥2.0 g/dL increase.

    Statistical analysis was performed for data up to Week 5 only.



Secondary Outcome Measures :
  1. Mean Change In Hemoglobin From Baseline To Week 5 [ Time Frame: Baseline (Day 1), Week 5 ]

    Mean change in hemoglobin from Baseline to Week 5 was calculated for each participant as:

    Hemoglobin Change = Hemoglobin (Week X) - Hemoglobin (Baseline), where Week X was any post-Baseline visit up to and including Week 5. Baseline was defined as the Day 1 value (prior to injection of study drug). The screening or most recent value prior to Day 1 was used for any participant with missing Day 1 information. If the Week 5 hemoglobin value was missing, the change from Baseline was imputed to be zero. Participants without any post-Baseline hemoglobin values were treated as non-responders.


  2. Participants Achieving A Hemoglobin Level ≥12.0 g/dL At Any Time From Baseline To Week 5 [ Time Frame: Baseline (Day 1) through Week 5 ]

    Participants who achieved a ≥12.0 g/dL hemoglobin level at any time from Baseline up to Week 5 are presented. Increase in hemoglobin at any time from Baseline up to Week 5 was calculated for each participant based on:

    Hemoglobin Change = Hemoglobin (Week X) - Hemoglobin (Baseline), where Week X was any post-Baseline visit up to and including Week 5. Baseline was defined as the Day 1 value (prior to injection of study drug). The screening or most recent value prior to Day 1 was used for any participant with missing Day 1 information. Participants without any post-Baseline hemoglobin values were treated as non-responders.


  3. Mean Change In TSAT From Baseline To Week 5 [ Time Frame: Baseline (Day 1), Week 5 ]

    Mean change in TSAT from Baseline to Week 5 was calculated for each participant as: TSAT Change = TSAT (Week 5) - TSAT (Baseline).

    TSAT, measured as a percentage, was part of the iron panel laboratory evaluations. Of the transferrin available to bind iron, this value indicates how much serum iron is bound. For example, a value of 20% means that 20% of iron-binding sites of transferrin are being occupied by iron. Baseline was defined as the Day 1 value (prior to injection of study drug). The screening or most recent value prior to Day 1 was used for any participant with missing Day 1 information. If the Week 5 TSAT value was missing, the change from Baseline was imputed to be zero.


  4. Mean Change In Functional Assessment Of Chronic Illness Therapy (FACIT)-Fatigue Score From Baseline To Week 5 [ Time Frame: Baseline (Day 1), Week 5 ]

    The FACIT-Fatigue questionnaire is a 13-item questionnaire designed and validated to specifically assess the presence and impact of treatment on fatigue and related symptoms, such as tiredness, on health-related quality of life in anemic participants with cancer. The questionnaire has 13 items, each measured on a 4-point Likert scale. Scoring ranges from 0 (the most fatigued) to 52 (the least fatigued) points, with higher scores representing better functioning or less fatigue.

    Mean change in FACIT-Fatigue Score from Baseline to Week 5 was calculated for each participant as:

    FACIT-Fatigue Score Change = FACIT-Fatigue Score (Week 5) - FACIT-Fatigue Score (Baseline).

    Baseline was defined as the Day 1 value (prior to first dose of study drug).The screening or most recent value prior to Day 1 was used for any participant with missing Day 1 information. If the Week 5 FACIT-Fatigue Score value was missing, the change from Baseline was imputed to be zero.


  5. Time To Hemoglobin Increase Of ≥2.0 g/dL Or A Hemoglobin Value Of ≥12.0 g/dL From Baseline [ Time Frame: From Baseline (Day 1) up to Week 5 ]
    The time to hemoglobin increase of ≥2.0 g/dL or hemoglobin value of ≥12.0 g/dL was defined as the days from Baseline (Day 1) to the first time the participant had an increase in hemoglobin of ≥2.0 g/dL or hemoglobin value of ≥12.0 g/dL, and was calculated using a Kaplan-Meier curve. Participants who did not have a hemoglobin increase of ≥2.0 g/dL or to a hemoglobin level ≥12.0 g/dL were censored at their last visit day. Participants without any post-Baseline study visits were not included.
