Clinical Trial Summary

This Phase 2 trial will assess the safety, tolerability, efficacy, imaging pharmacodynamics, and pharmacokinetics of RVP-001, a novel manganese-based MRI contrast agent, at three escalating dose levels. RVP-001 will be administered as a single IV bolus to subjects with known gadolinium-enhancing central nervous system (CNS) lesions (for example stable brain tumor or multiple sclerosis) who have recently had a gadolinium-based contrast agent (GBCA)-enhanced MRI of the brain.


Description:

Subjects will be pre-screened by study site personnel based on their upcoming appointment date for standard of care GBCA-enhanced MR imaging. Subjects may include individuals who have a stable primary brain tumor, metastatic brain tumors, multiple sclerosis, or other gadolinium-enhancing CNS lesions. Screening to select subjects for study participation will occur at or around the time of the subject's scheduled appointment. The appointment for standard of care imaging should take place at the designated study site. Following 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.

Outcome

Type Measure Description Time frame Safety issue
Primary Adverse Events Treatment-emergent adverse events for each dose level will be summarized. From time of dosing to 7 days post dose
Primary Lesion visualization criteria for RVP-001 enhanced MRI compared to unenhanced MRI The lesion visualization criteria is based on 3 criteria: border delineation, lesion contrast, and internal morphology. These criteria will be assessed by independent readers for representative lesions using the images acquired during the MRI performed with RVP-001. 1 day
Primary Lesion visualization criteria for RVP-001 compared to gadolinium-based contrast agent (GBCA) The lesion visualization criteria is based on 3 criteria: border delineation, lesion contrast, and internal morphology. These criteria will be assessed by independent readers for representative lesions using the images acquired with RVP-001 and those acquired with the GBCA.
For each reader, only matching lesion-pairs present in both MRI image sets (using GBCA and RVP-001) will be considered.
