About this study
The investigator hopes to introduce a novel MRI contrast agent with SeeMore ™ that directly defines viable myocardium. Identifying viable myocardium non-invasively using cardiac MRI is still a moving target and a question we plan to answer more definitively with the SeeMore ™ contrast. Though well tested in small and large animals and Phase I \& II clinical trials, the investigators would like to determine the efficacy of the SeeMore contrast further in a clinical setting.
SeeMore is a new manganese (Mn)-based intravenous imaging agent being developed to enhance magnetic resonance imaging (MRI). While Mn has long been known to have desirable magnetic and kinetic properties for MRI, use in humans was not initially possible due to cardiovascular depression and electrocardiogram (ECG) changes, including prolongation of PR and QTc intervals, associated with intravenous administration [1-5]. SeeMore provides Mn in a form that maintains the desired magnetic and kinetic properties while overcoming the cardiovascular toxicity of Mn. SeeMore is taken up into heart cells (primarily via addition of calcium to avoid cardiotoxic effects; please refer to US patent #5,980,863). The potential to distinguish healthy heart tissue from unhealthy heart tissue based on a specific sustained pattern of enhancement provides a basis for evaluating the performance of SeeMore in heart patients. It may be possible to enhance the utility of MRI for heart disease through the use of an imaging agent that is specifically taken up into heart cells. SeeMore is the only cardiac-specific agent being developed for this purpose. Unlike nuclear perfusion agents, SeeMore is not radioactive and does not require special handling, shielding, transport or storage. In addition, the specific pattern of enhancement achieved in the heart muscle persists over time, offering potential benefits over the nonspecific extracellular agents currently available for MRI or X-ray/CT procedures. This feature allows full use of the high resolution of MRI, since there is not a trade-off of high spatial resolution for temporal (first-pass) resolution. It is anticipated the features offered by SeeMore along with the high resolution, three dimensional attributes of MRI will result in higher accuracy than is available with other current modalities in practice, including stress echocardiograms, cardiac MRI using gadolinium contrast and nuclear studies such as SPECT and PET. This will be evaluated in this study and serve as the basis for pivotal registration studies.
All components of SeeMore™ are USP and are approved for use as drugs in man, orally and/or intravenously.
Read the detailed description
This is an open-label, baseline-controlled study. An initial cohort study of patients to conduct safety evaluation will be conducted before proceeding with the additional patients. In this initial cohort, a patient will be dosed based on the Phase 1 and 2 clinical trial data evaluation completed by Eagle Vision Pharmaceutical, Inc.
Starting 30 minutes before the cardiac MRI scan (CMR), the subjects will take a 4 mg tablet of ondansetron by mouth. CMR will subsequently take place and SeeMore™ will then be administered approximately 15 minutes into the scan for contrast enhanced images. SeeMore™ will be administered intravenously over approximately one minute. The subjects will each receive 0.28 mL/kg of SeeMore™. All subjects will be monitored closely from before ondansetron administration until their discharge from the imaging center. If positive delayed-enhanced MRI is detected, the subject will undergo MEMRI within 1 week. The investigators plan to perform imaging with CMR and SeeMore™ within a week after standard gadolinium-based delayed enhanced imaging by CMR (performed as clinically indicated within Stanford Hospital by the patient's physician) to directly compare the two different contrast enhanced images (SeeMore vs Gadolinium in determining viable myocardium).
Parameters to be Measured:
A standard physical examination will be performed within 24 hours prior to dosing and at the end of experimental MEMRI imaging (approximately 1 hour post dosing). A standard 12-lead EKG will be performed both before the experimental MR study and after the experimental MR study to assure no significant EKG changes have occurred. HR will be measured before and after the study. After the study, the patient will have another standard 12-lead EKG performed to compare with the pre-MRI 12-lead EKG. The patient's symptoms will be reassessed 1 hour and 1 year after infusion of the SeeMore contrast. Adverse events (AEs) and discomforts will be recorded until discharge from the imaging center. Any clinically relevant changes from baseline in vital signs, ECG rhythm, clinical chemistries or physical condition and all AEs will be followed until resolution or until the outcome is known. Primary efficacy will be based on determining whether the heart is normal or abnormal and if abnormal whether there is an infarction, ischemia or both. This provides the basis for calculating sensitivity, specificity, accuracy and predictive values. In addition, the location, size, conspicuity and associated confidence for any disease will be recorded.
The study will be stopped for any significant adverse cardiovascular event including cardiovascular death, myocardial infarction, ventricular arrhythmia, ICD firing, congestive heart failure, hospitalization, or syncope.

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing 'SEEMORE' - MANGANESE-ENHANCED MRI CONTRAST REAGENT in people with ISCHEMIC CARDIOMYOPATHY, run by Stanford University at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 6 inclusion and 13 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 2 Jan 2017. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 2 Jan 2017). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
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?
COMPARISON OF MYOCARDIAL INFARCTION SIZE MEASUREMENTS USING INVESTIGATIONAL MANGANESE-ENHANCED MRI (MEMRI) OR DELAYED GADOLINIUM ENHANCED MRI (DEMRI) (time frame: Day 1 (1 MRI)). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Jan 2017; AzTrials last refreshed its copy on 8 Nov 2026.
