Physiological Effects of N-Acetyl Cysteine in Patients With Multiple

Status Enrolling by invitation

Clinical Trial Summary

Multiple Sclerosis (MS) is a disease in which the myelin surrounding the nerve cells is damaged which affects functioning. MS usually is treated with medications designed to reduce the occurrence of future MS events. Evidence suggests that an important part of the disease process is damage to the myelin and brain caused by too much oxygen (sometimes called oxidative stress) or too much inflammation (or swelling). The overall goal of this study will be to determine whether N-acetyl cysteine (NAC) will help to support cerebral function in patients with Multiple Sclerosis (MS). This positron emission tomography magnetic resonance imaging (PET-MRI) study will utilize 18F-2-fluoro-2-deoxy-D-glucose fluorodeoxyglucose positron emission tomography FDG PET to measure cerebral metabolism, along with MRI analysis, to measure metabolism and structural effects of NAC in patients with MS.

Clinical Trial Description

The original protocol consisted of two arms. The first arm of this study will receive intravenous and oral NAC, a strong antioxidant that increases brain glutathione. NAC, is the N-acetyl derivative of the naturally occurring amino acid, L-cysteine. It is a common over-the-counter supplement that is also available as an injectable pharmaceutical that protects the liver in cases of acetaminophen overdose. Laboratory studies have displayed some benefits to use of NAC. It has the potential to reduce markers of oxidative damage, protect against cell death, and to increase glutathione in blood, which might be useful in preventing oxidative damage in MS patients. The second arm will be a waitlist control receiving standard MS care. It should be noted that both arms will receive standard of care treatment for MS while enrolled in the study. We amended this protocol to increase the enrollment with an additional 30 participants: 15 in a waitlist group and 15 will receive NAC. Subjects be randomized to either receive NAC or be placed in a waitlist control group. Those patients receiving NAC would receive a combination of IV and oral NAC for 4 months. We may obtain NAC serum measures that require a blood draw at three time points, one at scanning before receiving any NAC, one after the first infusion dose of NAC before the second dose, and another one at the last scan and the last dose of NAC. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
