About this study

Official title: Examination of Bone Defects and Microcirculation Using Volume Computed Tomography and Dynamic Contrast-enhanced Magnetic Resonance Imaging

Subject of the proposed study is the non-invasive in vivo imaging of bone, bone marrow and localized microcirculation in test animals with osteoporosis, fractures and after placement of bone substitute material with volume computed tomography (VCT) (animals only) and functional magnetic resonance imaging (MRI).

In vivo imaging by means of functional MRI and VCT is carried out in osteoporotic rats, both after the induction of fracture as well as after the placement of bone substitute material.

Furthermore, patients with asymptomatic MM are investigated with functional MR-Imaging (Dynamic Contrast Enhancement- MRI and Intravoxel incoherent motion (IVIM)-imaging) longitudinally to predict the occurrence of osteolysis and the time to progression regarding SLIM-CRAB-Criteria (Rajkumar et al., Lancet Oncology, 2014).

Hypothesis:

  1. Affection of microcirculation at the junction of bone and bone substitute material can be displayed by VCT and functional MRI
  2. Functional MRI has prognostic value regarding occurrence of osteolysis and progression to MM regarding SLIM-CRAB-Criteria
Read the detailed description

In an experimental study, rat models were used for imaging studies employing MRI (morphological, DCE- and DWI) and VCT. Mice were not used for imaging purposes due to the small size. Rats were shown to be of optimal size for small imaging studies.

144 patients with (suspected) asymptomatic MM were recruited for dynamic contrast-enhanced MRI (DCE-MRI) and diffusion weighted imaging (DWI) of the vertebral column as well as whole-body MRI using T1tse and STIR images every 6 months until progression and/ or occurrence of first osteolysis.

While during planning and initiation of this prospective trial MM was defined by CRAB-criteria only, in 2014 the SLIM-CRAB-criteria were proposed by the International Myeloma Working Group (Rajkumar et al., Lancet Oncology, 2014) with the goal to treat patients before development of osteolysis or other CRAB-criteria. These criteria were consequently introduced in clinical practice at our institution during the observation period of this study, which affects both inclusion and progression criteria of this study. In order to obtain a conclusive cohort with homogenous inclusion and progression criteria, SLIM-CRAB-criteria where retrospectively applied to restage all patients regarding inclusion and progression to MM defined by SLIM-CRAB-criteria.

What is being measured

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

  1. Changes of microcirculation at the interface between bone and implanted xenomaterial in animal models.

    Characteristics of the microcirculation within and in the close proximity of the bone defect in early stages and during the healing process after the placement of bone substitute materials in animal models. Correlation of functional imaging parameters derived from DCE-MRI, DWI and VCT assessed in the bone defect area with the later stage healing processes in the affected bone.

    Measured: VCT and MRI 2-6 weeks after xenomaterial implantation

  2. Progression to multiple myeloma defined by SLIM-CRAB-Criteria (Rajkumar, Lancet Oncology, 2014)

    In the study part applying functional imaging in asymptomatic myeloma patients, progression to Multiple Myeloma defined by SLIM-CRAB-Criteria is the primary outcome measure

    Measured: At inclusion in the study and in repetitive follow up every 6 months until progression requiring therapy, until contraindications for MRI are present, until patient wishes to leave the study or until death (assessed up to 20 years)

Secondary outcomes (1)
  1. Occurrence of osteolysis

    In the study part applying functional imaging in asymptomatic myeloma patients, occurrence of osteolysis in x-ray / CT imaging is the secondary outcome measure.

    Measured: At inclusion in the study and in repetitive follow up every 6 months until progression requiring therapy, until contraindications for MRI are present, until patient wishes to leave the study or until death (assessed up to 20 years)

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?

Changes of microcirculation at the interface between bone and implanted xenomaterial in animal models. (time frame: VCT and MRI 2-6 weeks after xenomaterial implantation). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01374412, which also lists 3 linked publications.

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.
