Trial Summary

What is the purpose of this trial?

This trial is testing a vitamin B3 supplement called Nicotinamide Riboside (NR) in adults who have muscle problems due to mitochondrial myopathy. The supplement aims to help their muscle cells produce more energy. Researchers hope this will improve symptoms in these patients. Nicotinamide riboside (NR), a form of vitamin B3, has been shown to boost NAD(+) levels and improve mitochondrial function.

Will I have to stop taking my current medications?

The trial protocol does not specify if you need to stop taking your current medications. However, you must avoid vitamin supplements or products with vitamin B3 forms for 14 days before and during the study.

What evidence supports the effectiveness of the drug Nicotinamide Riboside for mitochondrial myopathy?

Research shows that Nicotinamide Riboside, a form of vitamin B3, can boost NAD+ levels, which are important for energy production in cells. In studies with mice, it delayed disease progression and improved muscle health, suggesting it could be a promising treatment for mitochondrial myopathy. ^{1 2 3 4 5}

Is the Vitamin B3 derivative treatment generally safe for humans?

The research does not provide specific safety data for the Vitamin B3 derivative treatment, but other studies on different treatments for muscular conditions have shown that they were generally well-tolerated with mild side effects, mostly related to the digestive system. ^{6 7 8 9 10}

How is the drug Nicotinamide Riboside unique for treating mitochondrial myopathy?

Nicotinamide Riboside (NR) is unique because it is a precursor to NAD+, a vital molecule for energy production in cells, and it has been shown to increase NAD+ levels significantly, which may help improve muscle function in mitochondrial myopathy. Unlike other treatments, NR is generally recognized as safe and can be taken orally, making it a convenient option for patients. ^{4 5 11 12 13}

Findings from Research

In a 12-week randomized, placebo-controlled trial with 40 middle-aged, obese, insulin-resistant men, nicotinamide riboside (NR) supplementation did not significantly affect mitochondrial function, content, or morphology in skeletal muscle.

Despite a 14% decrease in the protein abundance of NAMPT, an enzyme involved in NAD+ biosynthesis, NR supplementation did not change NAD+ levels or the respiratory capacity of muscle mitochondria, suggesting limited efficacy in improving mitochondrial health in this population.

Nicotinamide riboside does not alter mitochondrial respiration, content or morphology in skeletal muscle from obese and insulin-resistant men. Dollerup, OL., Chubanava, S., Agerholm, M., et al.[2021]

Skeletal muscle cells primarily use the enzymes NAMPT, NRK1, and NRK2 to synthesize NAD+ from dietary supplements like nicotinamide mononucleotide (NMN) and nicotinamide riboside (NR), which are crucial for maintaining muscle health as we age.

Inhibition of NAMPT reduces NAD+ levels in muscle, but this can be restored by NMN and NR, indicating that both supplements are effective in enhancing NAD+ availability through pathways that depend on NRK1 and NRK2.

In a phase 2 study involving boys aged 4 to 8 with Duchenne muscular dystrophy, edasalonexent was found to be well-tolerated, with mild gastrointestinal side effects and no serious adverse events reported.

The treatment with edasalonexent at 100 mg/kg/day showed promising results in slowing disease progression and preserving muscle function, alongside reductions in NF-κB-regulated gene levels and improvements in muscle health biomarkers.

In a Phase 2 study involving 51 ambulant Duchenne muscular dystrophy (DMD) patients, drisapersen at a dose of 6 mg/kg/week showed a potential benefit in improving the 6-minute walking distance (6MWD) compared to placebo, with a mean difference of 27.1 meters at week 24.

Drisapersen was generally well-tolerated, with the most common side effects being injection site reactions and subclinical proteinuria, indicating a manageable safety profile for this treatment.

KPT-8602 (eltanexor) has shown promise as an oral treatment for Duchenne muscular dystrophy (DMD) in pre-clinical models, improving muscle integrity and overall outcomes in both zebrafish and mouse models.

The treatment not only enhanced locomotor behavior and muscle histology in D2-mdx mice but also shifted the immune response towards a more anti-inflammatory profile, suggesting it could be a safer alternative to corticosteroids for managing DMD.

A 24-week study involving 29 patients with various types of muscular dystrophy showed that the flavonoids- and omega-3-based supplement (FLAVOMEGA) was well tolerated with no adverse events reported, indicating its safety as a treatment option.

Significant improvements were observed in muscle function, specifically in the 6-minute walk distance and knee extension strength, particularly in patients with Limb Girdle Muscular Dystrophy and Facioscapulohumeral Muscular Dystrophy, suggesting FLAVOMEGA's potential efficacy as an adjuvant therapy.

Nicotinamide riboside (NR) is a promising NAD+ precursor that has shown potential health benefits in treating various conditions, including cardiovascular, neurodegenerative, and metabolic disorders, based on numerous animal and human studies.

Research indicates that NR may also have therapeutic applications against infections, such as SARS-CoV-2, but challenges related to its bioavailability and safety need to be addressed for effective translation into clinical use.

In an 8-week clinical trial with overweight but healthy participants, nicotinamide riboside (NR) significantly increased whole blood NAD+ levels in a dose-dependent manner, with increases of 22%, 51%, and 142% for doses of 100, 300, and 1000 mg, respectively.

The study found NR to be safe, with no significant adverse effects reported compared to placebo, and it did not negatively impact cholesterol levels or 1-carbon metabolism, supporting its potential as a dietary supplement.

Nicotinamide riboside (NR) was found to significantly reduce inflammation in mouse liver cells (hepatocytes) by decreasing pro-inflammatory markers and increasing anti-inflammatory molecules, indicating its potential as an anti-inflammatory agent.

NR also enhanced mitochondrial biogenesis in these cells, as evidenced by increased levels of mitochondrial markers, suggesting it may support cellular energy production and health in conditions of stress like fatty liver disease.
