Ferric Carboxymaltose to Improve Skeletal Muscle Metabolism in Heart Failure Patients With Functional Iron Deficiency

June 13, 2023 updated by: NYU Langone Health

The purpose of this study is to better understand how body levels of iron affect the ability to exercise in patients with heart failure (HF).

Heart failure is a condition in which abnormal pumping action of the heart reduces the flow of blood to the body. Patients with heart failure may feel shortness of breath or leg fatigue when they exercise. Iron is an essential nutrient in the diet. In heart failure patients, low body levels of iron might increase shortness of breath and fatigue.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Detailed Description

The purpose of this prospective, double blind parallel group randomized study is to compare the effects of ferric carboxymaltose vs. placebo on skeletal muscle mitochondrial oxidative capacity, submaximal exercise tolerance, and health-related quality of life in non-anemic Heart Failure (HF) patients with functional iron deficiency.

Eligibility Criteria

Eligibility Criteria

Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Ferric Carboxymaltose
HF patients with functional iron deficiency assigned to receive one-time dose of Ferric Carboxymaltose 750 mg. Participants will undergo serial assessment before and 4 weeks after study drug administration
Drug: Ferric Carboxymaltose
Intravenous Ferric Carboxymaltose 750 mg mixed under sterile conditions in 100 ml of normal saline for final concentration of 7.5 mg/ml and administered via volumetric infusion pump over 15 minutes.
Other Names:
  • Injectafer
Device: 31P MRS/MRI
Each participant will perform the same rhythmic plantar extension exercise protocol twice, for sequential acquisition of magnetic resonance spectroscopy (MRS) and magnetic resonance imaging (MRI) measurements. For the exercise protocol, the participant will lay supine on the scanning table with the right leg inside the volume coil. The exercise consists of repeated plantar flexion movements using resistance bands at a frequency of one repetition per second for 1-2 minutes. Data are collected continuously for 2 minutes before the exercise (baseline), during exercise, and 5 minutes after the exercise for the MRS and MRI experiments.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change From Baseline in Post-Exercise Phosphocreatine Recovery Time
Time Frame: Baseline, Week 4
Post-exercise phosphocreatine recovery time (in seconds) will be used to assess mitochondrial oxidative capacity. It is measured non-invasively with 31P-magnetic resonance spectroscopy.
Baseline, Week 4

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change From Baseline in 6-Minute Walk Test Distance
Time Frame: Baseline, Week 4
The 6-minute walk test measures the distance that a patient can walk on a flat, hard surface in a period of 6 minutes.
Baseline, Week 4
Change From Baseline in Kansas City Cardiomyopathy Questionnaire Score
Time Frame: Baseline, Week 4
23-item self-assessment of symptoms, physical and social limitations, and quality of life in patients with heart failure. KCCQ responses are provided along a rating scale continuum with equal spacing from worst to best. The total score ranges from 0-100, with higher scores indicating better health status. An increase in scores indicates health status improved during the observational period.
Baseline, Week 4
Change From Baseline in Hemoglobin Levels
Time Frame: Baseline, Week 4
Hemoglobin is a protein in red blood cells that carries oxygen. Hemoglobin levels (g/dL) were measured in laboratory analyses using patient blood samples.
Baseline, Week 4
Change From Baseline in Serum Ferritin Levels
Time Frame: Baseline, Week 4
Ferritin is a blood protein that contains iron. Serum ferritin levels (ng/ml) were measured in laboratory analyses using patient blood samples.
Baseline, Week 4
Change From Baseline in Transferrin Saturation
Time Frame: Baseline, Week 4
Transferrin saturation, measured as a percentage, is the value of serum iron divided by the total iron-binding capacity of the available transferrin. Transferrin saturation was measured in laboratory analyses using patient blood samples.
Baseline, Week 4
