New MRI dye could spot hidden prostate cancer cells
NCT ID NCT04261777
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This phase 3 trial tested whether an iron-based contrast agent called Ferumoxtran-10 (Ferrotran®) could improve MRI scans to find prostate cancer that has spread to lymph nodes. The study involved 172 men with newly diagnosed prostate cancer at intermediate to high risk of spread. Each patient received the contrast agent before MRI, and the results were compared to standard MRI and tissue samples after surgery. The trial was terminated early, so final conclusions are limited.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Ferumoxtran-10 (Ferrotran®), an iron-based contrast agent given as an intravenous infusion before MRI
- What this could lead to
- If successful, this could provide a more accurate, non-invasive way to detect cancer spread to lymph nodes in prostate cancer patients, potentially reducing unnecessary surgeries.
- What could go wrong
- The trial was terminated early, so results may be incomplete. The approach is still experimental and may not prove better than current methods.

Inclusion Criteria: 1. Voluntarily given and written informed consent. 2. Male ≥18 years of age. 3. Histologically newly-confirmed adenocarcinoma of the prostate. 4. Medium to high risk for lymph node metastasis, defined by either: 1. PSA ≥10 ng/mL or 2. Gleason-Score ≥7 or 3. Stage cT2b or cT2c or T3 or T4 5. Patients scheduled for radical prostatectomy (RP) with extended lymph node dissection (ePLND) between Day 7 and Day 42 after Ferrotran®-enhanced MRI. 6. Consent to practice contraception until end of study, including female partners of childbearing potential. Effective contraceptive measures include hormonal oral, injected or implanted female contraceptives, male condom, vaginal diaphragm, cervical cap, intrauterine device. Exclusion Criteria: 1. Any contraindication to MRI, as per standard criteria. 2. Any radiation therapy or systemic antiproliferative (chemo-, immuno, or hormonal) therapy for prostate cancer (Lupron, Taxotere, Casodex, Eulexin, Zoladex, etc.) prior to screening and until after post-surgery FUP MRI. 3. Known hypersensitivity to Ferrotran® or its components such as dextran. 4. Known hypersensitivity to other parenteral iron products. 5. Acute allergy, including drug allergies and allergic asthma. 6. Evidence of iron overload or disturbances in the utilisation of iron (e.g., haemochromatosis, haemosiderosis, chronic haemolytic anaemia with frequent blood transfusions). 7. Presence of liver dysfunction. 8. Any other investigational medicinal product within 30 days prior to receiving study medication until end of study visit. 9. Simultaneous participation in any other clinical trial. 10. Abnormal safety laboratory values at screening or baseline that are assessed by the principal investigator as clinically relevant. 11. Patients not able to declare meaningful informed consent on their own (e.g. with legal guardian for mental disorders), or other vulnerable patients (e.g. under arrest). 12. Patients with acute SARS-CoV-2 infection
