E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
Detection of thrombi in the arterial vasculature and cardiac chambers |
|
MedDRA Classification |
E.1.3 | Condition being studied is a rare disease | No |
E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To quantitatively determine the imaging properties of EP-2104R for characterization of the thrombus at different time points post-injection (e.g. signal intensity/enhancement, contrast to noise ratio, assessment of thrombus size). |
|
E.2.2 | Secondary objectives of the trial |
Secondary study objectives include to determine region-specific sensitivity compared to a reference standard generated by a study institution’s index diagnostic imaging data; to qualitatively and quanitatively determine the imaging properties of EP-2104R for vascular imaging post-injection; and to determine the preliminary safety of EP-2104R. |

E.2.3 | Trial contains a sub-study | Information not present in EudraCT |
E.3 | Principal inclusion criteria |
- able to understand and provide written informed consent; - ≥ 18 years of age; - have: a. a diagnosis of thrombus by an indexing exam; or b. have imaging evidence such as a complex plaque or stenosis of 80% or greater indicating a strong likelihood of thrombus in the carotid artery; or c. have imaging evidence such as a complex plaque greater than 4 mm thickness indicating a strong likelihood of thrombus in the aorta; - are clinically stable for at least 24 hours prior to first MR imaging session; - are a candidate for MR imaging within 48 hours of the indexing exam; - are able to undergo an MR scan for at least 30 minutes in the supine position; - have a negative pregnancy test at baseline if female of child-bearing potential; and - be clinically stable in the opinion of the investigator and have no other life-threatening illness or organ system dysfunction, which would either intervene with their safety or interfere with the evaluation of EP-2104R. |
|
E.4 | Principal exclusion criteria |
- women who are pregnant or lactating; - if there has been any major therapeutic intervention (i.e. lysing agent, thrombectomy) between the initial positive indexing exam and EP-2104R administration; - if there is a specific magnetic resonance exclusion criteria including but not limited to contraindications such as a pacemaker, ear implants, internal defibrillator, internal infusion pumps, ferromagnetic intracranial aneurysm clips, any site-specific MR exclusion, or severe claustrophobia; - if they are on mechanical ventilation or are otherwise not considered clinically stable; - if they have received any investigational drug or device within 30 days prior to EP-2104R administration; and - if there is a known hypersensitivity to any contrast agent. |
|
E.5 End points |
E.5.1 | Primary end point(s) |
- The signal intensity of the thrombus region as a function of time relative to drug injection; - The signal intensity of the blood as a function of time relative to drug injection; - The signal intensity of background tissue proximal to the thrombus region as a function of time relative to drug injection; - The mean and standard deviation of signal intensity of a uniform region of lung or air outside the body as a function of time relative to drug injection, as an estimate of the noise level. |
