Study hypothesis
To assess the fasibility of manganese chloride tetrahydrate (CMC-001©) as a contrast medium in liver Magnetic Resonance Imaging (MRI) scanning.
The secondary objectives are to further evaluate the safety and tolerability of CMC-001© in patients.
Ethics approval
Approval received from the official board of the UMC St Radboud of Nijmegen on the 25th May 2004 (ref: SE/AMO 0339).
Study design
The study was open and non-randomised, with each patient being his own control. The evaluation of the MR images was performed by two independent observers.

Condition
Verified liver metastases
Intervention
CMC-100© is a contrast agent taken by the oral route intended for use in MRI scanning of the liver, gallbladder and surrounding tissues. In this, the first phase II trial, the intention was to find out how well liver metastases could be visualised in contrast to the surrounding healthy liver tissue. To this end a MRI image taken before contrast was compared to a MRI picture taken three hours after contrast by two independent observers. Some of the patients also had a third MRI 24 hours after contrast in order to see if the gallbladder could be visualised. 48 hours after contrast the patients were called on the phone out of safety reasons in order to find out if they had experienced any Adverse Events (AEs).
No interventions besides the MRI and a screen of blood samples for safety analyses and a special blood sample for manganese alalyse were done.

Manganese chloride tetrahydrate (CMC-001©) contrasting agent
Primary outcome measure
The primary endpoint was efficacy. The MR image before contrast was compared to the MR image three hours after contrast and in a small number of patients also a MR image 24 hours after contrast.
Secondary outcome measures
Secondary parameters was the safety of the contrast. AEs were recorded as long as the patients were staying at the clinic and were called 48 hours after contrast and interviewed about any untoward experiences.
