Safety and Efficacy Evaluation of DOTAREM® in MRI of Central Nervous System (CNS) Lesions - Full Text View

Sponsor:	Guerbet
Information provided by (Responsible Party):	Guerbet
ClinicalTrials.gov Identifier:	NCT01211873

Purpose

The purpose of this study is to look at the safety (what are the side effects)and efficacy (how well does it work) of Dotarem® when used in taking images of the brain / spine. The results will be compared to the results of MRI taken without Dotarem.

Primary Outcome Measures:

MRI lesion visualization with 3 parameters (lesion border delineation, internal morphology and degree of contrast enhancement) on 3-point scales. [ Time Frame: up to 24 hours ] [ Designated as safety issue: No ]
To demonstrate the superiority of combined unenhanced and Dotarem enhanced MRI compared to unenhaced MRI in terms of lesion visulization.

Secondary Outcome Measures:

The quality of images on 3-point scale: poor, fair or good. [ Time Frame: up to 24 hours ] [ Designated as safety issue: No ]
Level of diagnostic confidence on 5-point scale ranging from nil to excellent with poor, moderate and high as intermediate grades. [ Time Frame: up to 24 hours ] [ Designated as safety issue: No ]
Number of lesions with MRI signal intensity changes after contrast agent injection. [ Time Frame: up to 24 hours ] [ Designated as safety issue: No ]
Number of participants with Adverse Events as a measure of safety and tolerability. [ Time Frame: up to 29 days ] [ Designated as safety issue: Yes ]
Measure vital signs (supine systolic and diastolic blood pressures, pulse). [ Time Frame: up to 24 hours ] [ Designated as safety issue: Yes ]
Measure ECG [ Time Frame: up to 24 hours ] [ Designated as safety issue: Yes ]
Injection-site tolerance on the Visual Analog Scale from 0 (no pain) to 10 (maximal pain). [ Time Frame: up to 24 hours ] [ Designated as safety issue: Yes ]
Measure blood sample. [ Time Frame: up to 24 hours ] [ Designated as safety issue: Yes ]

Arms	Assigned Interventions
Experimental: Dotarem (gadoterate meglumine )	Drug: Dotarem (gadoterate meglumine) 0.1 mmol/kg by body weight, single IV injection Other Name: Dotarem

Detailed Description:

This is a study involving the use of Magnetic Resonance Imaging (MRI) contrast agents called Dotarem®. The purpose of this study is to look at the safety (what are the side effects) and efficacy (how well does it work) of Dotarem® when used for taking images of the brain and spine. The results of the MRI will be compared to the results of images taken without Dotarem®.

Eligibility

Ages Eligible for Study:	2 Years and older

Criteria

Inclusion Criteria:

Adult subject and pediatric subjects (aged greater than or equal to two (2) years).
Is referred for a contrast-enhanced MRI of the CNS based on the results of a previous imaging procedure.
Female of childbearing potential patients must have effective contraception (contraceptive pill or intra-uterine device) or be surgically sterilized or post-menopausal (minimum 12 months amenorrhea), or have a documented negative urine pregnancy test within 24 hours prior to study MRI.
Has been fully informed about the study, and has consented to participate.

Exclusion Criteria:

Having acute or chronic grade IV or V renal insufficiency.
Known class III/IV congestive heart failure.
Suffering from long QT syndrome.
Unstable health condition or circumstances (e.g. suffering from severe claustrophobia).
Having any contraindications to MRI such as a pace-maker, magnetic material or any other conditions that would preclude proximity to a strong magnetic field.
Known allergy to Gadolinium chelates.
Having received any contrast agent within 3 days prior to study contrast administration, or is scheduled to receive any contrast agent within 24 hours after the study contrast administration.
Pregnant, breast feeding, or planning to become pregnant during the trial.
Previously participated in this trial.
Having participated within 30 days in another clinical trial involving an investigational drug.
Any condition which, based on the investigator's clinical judgement, would prevent the patient from completing all trial assessments and visits.
Inability or unwillingness to cooperate with the requirements of this trial.
