Magnetic Resonance Imaging Using Ferumoxytol in Patients With Primary Brain Cancer or Brain Metastases From Lung or Breast Cancer

Rationale: Diagnostic procedures, such as magnetic resonance imaging (MRI) using ferumoxytol, may help find and diagnose primary brain cancer or brain metastases.Purpose: This randomised clinical trial is studying how well MRI using ferumoxytol works in finding out the extent of the tumour in patients with primary brain cancer or brain metastases from lung or breast cancer.

Further Details

Primary Outcomes:

• Determine, preliminarily, the safety and efficacy of magnetic resonance imaging (MRI) using ferumoxytol in patients with primary malignant brain tumours or brain metastases secondary to lung or breast cancer.
• Determine, preliminarily, the optimum post-injection timing of ferumoxytol for imaging in these patients.
• Determine whether there are major differences in magnetic field strength for imaging in these patients.

Secondary Outcomes:

• Compare, preliminarily, ferumoxytol magnetic resonance angiography (MRA) with gadolinium MRA in these patients.
• Determine, preliminarily, the number and size of tumours imaged in these patients.
• Determine, preliminarily, tumour vascularity in these patients.
• Determine, preliminarily, histology and electron microscopy on tissue samples in these patients.
• Compare, preliminarily, imaging differences in patients who have received prior therapy vs no prior therapy (radiotherapy and/or chemotherapy).

This is a randomised, pilot study. Patients are randomised to 1 of 2 magnetic field strengths (1.5 Tesla vs 3.0 Tesla) of magnetic resonance angiography (MRA).Patients receive ferumoxytol IV for up to 1 hour (single or multiple bolus infusions over 10-15 seconds each). Patients then undergo MRA immediately after each bolus infusion. Patients also undergo MRI at 4-6 hours, 16-20 hours, 24-28 hours, 48-52 hours, and 72 hours (if feasible) after receiving ferumoxytol.
