Brief Summary:
This study will define the effects of ferumoxytol on electrocardiogram (ECG) data as well as evaluate pharmacokinetics

Condition or disease Intervention/treatment Phase
Anemia Drug: ferumoxytol Drug: moxifloxacin Drug: placebo Phase 1

Detailed Description:
This trial will be conducted in order to provide an evaluation of the potential of ferumoxytol to cause cardiac arrhythmia in accordance with the International Conference on Harmonization (ICH) E14 guidance. The purpose of this trial is to define the effects of ferumoxytol on electrocardiogram (ECG) data. Pharmacokinetics will also be evaluated at multiple time points as specified. Subject safety will be monitored throughout the study.

Study Type : Interventional  (Clinical Trial)

Drug Information available for: Ferumoxytol

Primary Outcome Measures :
  1. To define the effect of two doses of 510 mg ferumoxytol administered within 24 hours on the QTcI interval compared to placebo and to a single dose of 400 mg moxifloxacin.
  2. To define the effect of two doses of 510 mg ferumoxytol administered within 24 hours on QT, QTcB, QTcF and heart rate (HR).
  3. To assess the pharmacokinetics of two doses of 510 mg ferumoxytol administered within 24 hours.

Secondary Outcome Measures :
  1. To describe the relationship between exposure to ferumoxytol and ECG parameters (QTcI, QT, QTcB, QTcF and HR).
  2. To assess the safety and tolerability of a supratherapeutic dose of ferumoxytol (2 doses of 510 mg ferumoxytol administered within 24 hours).

Exclusion Criteria:

  • Subjects currently participating in a clinical trial with another investigational new drug or device or who have received an investigational new drug or device within 30 days or 5 half-lives (whichever is longer) prior to randomization into this study.
  • Subjects who have been on parenteral or oral iron therapy within 30 days prior to dosing.
  • Subjects with active infections requiring ongoing treatment.
  • Subjects with a positive human immunodeficiency virus type 1 or type 2 (HIV-1 or HIV-2) antibody, Hepatitis B surface antigen (HBsAg) or Hepatitis C antibody test.
  • Abnormal liver function tests.
  • Subjects who have had malignancy (except for non-melanoma of the skin), unless the subject has received curative treatment and has been disease free for > 2 years.
  • Subjects with a history of risk factors for Torsades de pointes (TdP) [e.g., family history (parents or siblings) of long QT syndrome], history of fainting, unexplained loss of consciousness or convulsions.
  • Clinically relevant abnormality on screening ECG
  • Subjects who have a sustained supine systolic blood pressure (SBP) > 150 mmHg or < 90 mmHg or a diastolic blood pressure (DBP) < 45 or > 95 mmHg at screening or baseline.
  • Subjects who have a pulse rate at rest of < 45 bpm or > 100 bpm.
  • Subjects who are unable to stop smoking during the study (Day -1 to Day 7). Subjects who smoke 10 or more cigarettes a day.
  • Excessive consumption (> 6 units per day) of food or beverages with xanthine or caffeine bases (e.g., tea, coffee, chocolate, cola; 1 unit of caffeine is contained in 6 oz of coffee, 4 oz of energy drink, 24 oz of cola, 12 oz of tea and 3 oz chocolate).
  • History of regular alcohol consumption exceeding 7 drinks/week for women or 14 drinks/week for men.
  • Subjects with any allergies to iron products, moxifloxacin or multiple drug (two or more) allergies as reported by the subject or as determined by the investigator.
  • Subjects who have taken medications [with the exception of Tylenol (acetaminophen) ≤ 2g/day, multi-vitamin that does not contain iron, hormonal contraception for females and hormone replacement therapy (HRT) in the case of menopausal subjects] within 7 days or 5 half-lives (whichever is longer) prior to randomization into this study.
  • Subjects who the Investigator determines to have a medical status that would preclude the patient's participation in this protocol or who, for any reason, are deemed by the Investigator to be inappropriate for this study, including subjects who are unable to communicate or to cooperate during the study.
  • Subjects with screening lab results that fall outside of the normal range limits and are considered to be clinically significant upon review by the Investigator.
