About this study

Official title: Pilot Differentiation of Bone Sarcomas and Osteomyelitis With Ferumoxytol-Enhanced MRI

This pilot trial studies the differentiation of bone sarcomas and osteomyelitis with ferumoxytol-enhanced magnetic resonance imaging (MRI). Imaging procedures that allow doctors to more accurately differentiate between malignant bone sarcomas and osteomyelitis may help in diagnosing patients correctly and may result in more timely treatment.

Read the detailed description

BACKGROUND; In this study, T1, T2, and T2* represent parameters of magnetic resonance imaging (MRI).

The T1 relaxation time, also known as the spin-lattice relaxation time, is a measure of how quickly the net magnetization vector (NMV) recovers to its ground state in the direction of B0. T1 is assessed immediately post-contrast. A T1-weighted image (T1WI ) is one of the basic pulse sequences in MRI and demonstrates differences in the T1 relaxation times of tissues. A T1WI relies upon the longitudinal relaxation of a tissue's net magnetization vector (NMV).

T2 is a time constant for the decay of transverse magnetization arising from natural interactions at the atomic or molecular levels, and be considered the "natural" or "true" T2 of the tissue. However, in any nuclear magnetic resonance (NMR) experiment, transverse magnetization decays much faster than would be predicted by natural atomic and molecular mechanisms. Accordingly, T2 * is the time constant for the decay of transverse magnetization as observed in a tissue during a MRI scan, and be considered the"effective T2" (represented as T2*). T2* is always ≤ T2. In this study, T2 * is assessed after 24 hours.

OUTLINE:

Patients receive ferumoxytol intravenously (IV) and then undergo ferumoxytol-enhanced MRI up to 1 hour after infusion and up to 24 hours post-infusion.

PRIMARY OBJECTIVES:

  • Establish magnetic resonance (MR) imaging characteristics of bone sarcomas and osteomyelitis based on their ferumoxytol-enhancement on relatively early post-contrast T1-weighted images.
  • Establish MR imaging characteristics of bone sarcomas and osteomyelitis based on their ferumoxytol-enhancement on delayed postcontrast T2-weighted images.
  • Establish T2-weighted MR imaging characteristics of iron-labeled mesenchymal stem cell (MSC) in osteonecrotic bone over time, before and after surgical core decompression and bone marrow implantation.
  • Adding a second branch for patients who can not receive ferumoxytol but still getting the MRI exam. These patients will server as controls.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. T2* Relaxation Time of Bone Sarcomas and Osteomyelitis Subjects

    Differentiation of bone sarcomas and osteomyelitis with ferumoxytol-enhanced magnetic resonance imaging (MRI) was assessed as the difference of mean T2 * relaxation time of bone sarcoma and osteomyelitis subjects. The outcome is reported as the difference of the mean T2 * values, with standard deviation.

    Measured: 24 hours

Secondary outcomes (4)
  1. Differentiation of Bone Sarcomas Pre-ferumoxytol and Post-ferumoxytol Contrast

    Differentiation of bone sarcomas pre-ferumoxytol and post-ferumoxytol contrast was assessed by difference of mean T2 * relaxation time pre-ferumoxytol and post-ferumoxytol contrast, in bone sarcoma subjects only.

    Measured: Baseline and Post-Treatment-24 hours

  2. Differentiation of Lymphoma and Bone Sarcomas With Ferumoxytol-enhanced MRI

    Differentiation of lymphoma from bone sarcoma was assessed as the difference of mean T2 * relaxation time determined by ferumoxytol-enhanced MRI.

    .

    Measured: 24 hours

  3. Differentiation of CD68-positive Tumor-associated Macrophages (TAM) in Lymphomas and Bone Sarcomas

    Differentiation of CD68-positive tumor-associated macrophages (TAM) between lymphoma and bone sarcoma was assessed as the difference of mean area density of CD68-positive TAM in those populations.

    Measured: 24 hours

  4. Differentiation of CD163-positive Tumor-associated Macrophages (TAM) in Lymphomas and Bone Sarcomas

    Differentiation of CD163-positive tumor-associated macrophages (TAM) between lymphoma and bone sarcoma was assessed as the difference of mean area density of CD163-positive TAM in those populations.

    Measured: 24 hours

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Feraheme and Magnetic Resonance Imaging (MRI) scan in people with Bone Cancer and Chondrosarcoma, run by Heike E Daldrup-Link at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 27 Dec 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 18 Jun 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

T2* Relaxation Time of Bone Sarcomas and Osteomyelitis Subjects (time frame: 24 hours). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 27 Dec 2023.
