Research Sponsored by Clene Nanomedicine
Eligibility Criteria Checklist
Specific guidelines that determine who can or cannot participate in a clinical trial
Must have
Cohort 1: Stable treatment with natalizumab, defined as a stable dose maintained at the standard infusion interval of 28-days (±5 days) for at least the prior six (6) months
Cohort 1: Clinical diagnosis of Relapsing Multiple Sclerosis (RMS) (meeting McDonald criteria, 2017)
Must not have
Cohort 2: History of AQP4, MOG Ab(+) status, or documented ≥ 3 contiguous segment lesion in the spinal cord
Cohort 1: Patients with clinically significant hepatic or renal dysfunction or clinical laboratory findings that would limit the interpretability of change in liver or kidney function, or those with low platelet counts (< 150 x 109 per liter) or eosinophilia (absolute eosinophil count of ≥500 eosinophils per microliter) at Screening

Summary

This trial is testing a new drug for MS patients who have been diagnosed within the last 15 years. The goal is to see if the drug is safe and effective, and how it affects the brain.

Who is the study for?
Adults aged 18-70 with Multiple Sclerosis (MS) diagnosed within the last 15 years. Participants must have stable MS or be on specific therapies for at least 48 weeks. They should not have had recent relapses, metal implants affected by MRI, significant medical conditions, drug abuse history, pregnancy plans during and post-trial without contraception use, or a gold allergy.
What is being tested?
The REPAIR-MS study is testing CNM-Au8 gold nanocrystals to see if they can improve brain metabolism in MS patients. This involves taking the treatment and having special brain scans called '31P-MRS imaging' over a period of 12 weeks to measure any changes.
What are the potential side effects?
While side effects are not explicitly listed here, typical clinical trial concerns include potential allergic reactions to the gold nanocrystals and issues related to frequent MRI scans such as discomfort or claustrophobia.
