Without the participation of people with MS, it would be impossible to develop new and better therapies and other interventions.

Phase 2 Ascending Dose Safety and Efficacy Study of RVP-001, a Manganese-based MRI Contrast Agent

Study Purpose

This Phase 2 clinical trial will study RVP-001, a new manganese-based MRI contrast agent, in people who are known to have gadolinium-enhancing central nervous system (CNS) lesions, for example brain tumors or multiple sclerosis. The goal of this study is to assess safety, efficacy, and pharmacokinetics of RVP-001 at three dose levels. The study will also compare RVP-001 imaging to gadolinium-based contrast agent (GBCA) imaging. A single dose of RVP-001 will be administered to each subject. Subjects will have known gadolinium-enhancing CNS lesions and will have a gadolinium-based contrast agent-enhanced MRI of the brain 2-14 days before receiving RVP-001 with imaging. The ultimate goal of this research program is development of a gadolinium-free alternative to current general purpose MRI contrast agents.

Recruitment Criteria

Accepts Healthy Volunteers Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms	No
Study Type An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes. An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes. Searching Both is inclusive of interventional and observational studies.	Interventional
Eligible Ages	18 Years - 75 Years
Gender	All

More Inclusion & Exclusion Criteria

Inclusion Criteria:

Patients with known enhancing CNS lesions, including but not limited to gliomas, meningiomas, glioblastomas, schwannomas, brain metastases, multiple sclerosis lesions, that are on an ongoing follow-up MRI schedule. 3. Patients who have had a GBCA-enhanced MRI within the past 14 days which demonstrated focal areas of disrupted Blood Brain Barrier (BBB) (e.g., primary and secondary tumors, focal inflammatory disorders) including at least one enhancing lesion of minimum 5 mm (long axis) 4. Acceptable renal function.

Exclusion Criteria:

1. Serious non-malignant disease that could compromise protocol objectives in the opinion of the investigator and/or the Sponsor. 2. Body mass index (BMI) greater than 35. 3. Patients with clinically significant cardiac disease. 4. MRI incompatibility

Trial Details

Trial ID: This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.	NCT06322342
Phase Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans. Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data. Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs. Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.	Phase 2
Lead Sponsor The sponsor is the organization or person who oversees the clinical study and is responsible for analyzing the study data.	Reveal Pharmaceuticals Inc.

Additional Details

Subjects may include individuals who have a stable primary brain tumor, metastatic brain tumors, multiple sclerosis, or other gadolinium-enhancing CNS lesions. Following the screening GBCA-enhanced MRI scan to confirm presence of target lesion(s), a baseline unenhanced MRI scan will be performed prior to RVP-001 injection. Dynamic imaging will be performed in conjunction with RVP-001 injection. Steady state imaging will follow at multiple time points during the first hour following dose administration to characterize the pharmacodynamics of RVP-001 and to assess its ability to enhance visualization of areas with disrupted blood brain barrier and/or abnormal vascularity of the central nervous system. Three dose cohorts are planned. An unenhanced MRI scan follow-up study will be performed between one week and six weeks following the administration of RVP-001. Safety will be evaluated throughout the study by assessing the following parameters: adverse events (AEs), physical examinations, injection site monitoring, electrocardiograms (ECGs), vital signs, clinical laboratory evaluations, medical history, and prior and concomitant medications.
