The primary objective is to assess the feasibility of manganese chloride tetrahydrate (CMC-001©) as a contrast medium in liver Magnetic Resonance Imaging (MRI) scanning in patients with liver metastases in comparison with gadolinium Benzyloxypropionictetraacetate (BOPTA) (MultiHance©) MRI.
Approval received from the Regional Ethics Board in Stockholm on the 30th March 2005 (ref: 2005/305-31/1).
The study will be of a single centre, randomised and open cross-over design.
Primary study design
Secondary study design
Randomised controlled trial
Patient information sheet
Each patient will have two MRI sessions, one with each product. This means that each patient will be his/her own control. The evaluation of MR images will be performed by two independent observers. The final evaluation will however be made in consensus.
When a suitable patient arrives at the clinic he/she will be informed about the trial both orally and in writing and is offered a to take part in the trial with two different MRI sessions, one with Gadolinium BOPTA and a second MRI with CMC-001© as contrast. After that he/she will sign the informed consent form.
The patients will visit the clinic three times:
1. For screening and eligibility test
2. For MR imaging of the first contrast
3. For MR imaging of the second contrast
After this, they will be called by phone 24 and 48 hours and asked about Adverse Events (AEs).
The order of administration of the two contrast agents is randomised. MRI after CMC-001© is performed three hours after contrast and MRI after MultiHance©, the comparator, is performed two hours after contrast.
Electrocardiogram (ECG), vital signs, blood for laboratory analyses and urine is drawn at screening and after MRI.
Manganese chloride tetrahydrate (CMC-001©) and gadolinium BOPTA (MultiHance©).
Primary outcome measure
The primary objective is to assess the feasibility of CMC-001© as a contrast medium in liver MRI scanning in patients with liver metastases in comparison with gadolinium BOPTA (MultiHance©) MRI.
Secondary outcome measures
The secondary objectives are to further evaluate the safety and tolerability of CMC-001© in patients:
1. ECG, vital signs, blood for laboratory analyses and urine is drawn at screening and after MRI
2. AEs are asked for during the whole trial as well as at the phone calls 24 and 48 hours after contrast

11. The patient has newly discovered unstable diabetes or undergoes haemodialysis or peritoneal dialysis
12. The patient has a known or suspected clinically severe concurrent illness that may influence the renal function or has undergone kidney, liver or bone marrow transplantation
13. The patient has a concurrent severe illness in the Gastrointestinal (GI) tract like paralysis or malabsorption or clinically manifest icterus
14. Known Human Immunodeficiency Virus (HIV) infection or Acquired Immune Deficiency Syndrome (AIDS)
15. Known hepatitis
16. Known cirrhosis
17. The patient has uncompensated cardiac failure (cardiac failure New York Heart Association [NYHA] grade IV)
18. A patient may be excluded during the trial based on the clinical judgement of the clinician or the radiologist
