Testing a new manganese-based MRI contrast agent for brain lesions

A Multi-Center, Phase 2, Open Label, Ascending Dose Study to Evaluate the Safety and Efficacy of RVP-001 and to Identify an Appropriate Dose to Detect CNS Lesions in Adult Patients

Phase 2 Interventional Reveal Pharmaceuticals Inc. · NCT06322342

This study is testing a new MRI contrast agent made from manganese to see if it can safely and effectively improve imaging of brain lesions in patients with conditions like brain tumors and multiple sclerosis.

What this trial studies

This Phase 2 clinical trial evaluates RVP-001, a manganese-based MRI contrast agent, in patients with gadolinium-enhancing central nervous system lesions such as brain tumors and multiple sclerosis. The study aims to assess the safety, efficacy, and pharmacokinetics of RVP-001 at three different dose levels, comparing its imaging capabilities to traditional gadolinium-based contrast agents. Participants will undergo a series of MRI scans before and after receiving RVP-001 to monitor its effectiveness in enhancing visualization of lesions. The ultimate goal is to develop a gadolinium-free alternative for MRI imaging.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18-75 with known gadolinium-enhancing CNS lesions who have undergone a recent GBCA-enhanced MRI.

Not a fit: Patients with serious non-malignant diseases, significant cardiac issues, or MRI incompatibility may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a safer, gadolinium-free option for MRI contrast that enhances imaging of brain lesions.

How similar studies have performed: While this approach is novel, previous studies have shown promise in developing alternative MRI contrast agents.
