This trial aimed to study the performance of Elucirem (gadopiclenol) in Dynamic Susceptibility Contrast Magnetic Resonance Imaging (DSC-MRI) perfusion of brain gliomas.

The trial was designed as a prospective, multi-center, randomized, controlled and parallel group comparison.

This study aimed to enrol 138 patients in Italy, Poland and Hungary.

During the course of the trial, patient underwent a DSC-MRI perfusion using Elucirem or Dotarem. A safety visit was performed 1 day after the MRI visit. Confirmation of tumor grade diagnosis, if available, was collected up to 30 days after visit 2. Primary end point was assessed by independent off-site blinded readers.

Inclusion Criteria:

1. Female or male adult patient (patient having reached legal majority age).
2. Patient with naive or recurrent primary glial tumor detected at a previous Computed Tomography (CT) or MR imaging, and scheduled for a follow-up contrast-enhanced MRI. Tumor grade (confirmed or highly suspected) should be available in patients' medical records.
3. Patient or, if the patient is unable to provide informed consent, the patient's legally acceptable representative and/or impartial witness, having read the information and having provided patient's consent to participate in writing by dating and signing the informed consent prior to any trial related procedure being conducted.
4. Patient affiliated to national health insurance according to local regulatory requirements.

Exclusion Criteria:

1. Patient with known contra-indication(s) to the use or with known sensitivity to one of the products under investigation or to other Gadolinium-Based Contrast Agents (GBCA) (such as hypersensitivity, post-contrast acute kidney injury).
2. Patient presenting with any contraindication to MRI examinations.
3. Post treatment patient presenting with pseudo-progression instead of tumor recurrency.
4. Patient presenting with severe renal insufficiency, defined as an estimated Glomerular Filtration Rate (eGFR) < 30 mL/min/1.73 m² assessed within 1 week prior to contrast agent injection.
5. Patient having received any contrast agent (for MRI or CT) within 3 days prior to IMP administration or scheduled to receive any contrast agent within 24 hours after IMP administration.
6. Pregnant female patient (a female patient of childbearing potential or with amenorrhea for less than 12 months must have a negative pregnancy test within 1 day prior to trial MRI and must be using medically approved contraception method until the last trial visit).
7. Patient having received any investigational medicinal product within 7 days prior to trial entry or scheduled to receive any investigational treatment in the course of the trial.
8. Patient previously randomized in this trial.
9. Patient with anticipated, current or past condition (medical, psychological, social or geographical) that would compromise the patient's safety or her/his ability to participate in the trial.
10. Patient unlikely to comply with the protocol, e.g., uncooperative attitude, inability to return for follow-up visits and/or unlikelihood of completing the trial.
11. Patient related to the investigator or any other trial staff or relative directly involved in the trial conduct.

Baseline description for safety population (patients received an injection of contrast agent): A total of 136 patients including 67 patients who received an injection of Elucirem and 69 patients who received an injection of Dotarem.

From the beginning of patient's participation in the trial (Informed Consent Form signature) until the end of the participation (1 day after IMP administration for the patients without biopsy or surgery done, maximum 30 days after IMP administration for the patients with biopsy or surgery done).

AEs occurring during or after IMP administration until the end of the participation (maximum 30 days) for safety population.

Safety population: the patients who received an IMP of the study (67 patients received an injection of Elucirem group and 69 patients received an injection of Dotarem).
