Trial summary

Mitochondria are important parts of the cell that are responsible for producing energy. The amount of energy they produce depends on how much energy the body needs to function and this energy production can be severely impaired in people with mitochondrial disease. Read more about this study

About this study

Official title: The Role of Nicotinamide Riboside in Mitochondrial Biogenesis

Mitochondria are important parts of the cell that are responsible for producing energy. The amount of energy they produce depends on how much energy the body needs to function and this energy production can be severely impaired in people with mitochondrial disease. Symptoms of mitochondrial disease vary widely but usually involve the brain, nerves and muscles, as these are tissues that need a lot of energy. Mitochondrial disorders affect 1 in 5000 of the UK population and there is currently no cure.

Some scientists think that increasing the number of mitochondria in the body (mitochondrial biogenesis) might be an effective treatment for the symptoms of mitochondrial disease. Studies carried out in mice have shown that a type of B-vitamin called Nicotinamide Riboside (NR) is able to increase the number of mitochondria, leading to increased energy and a reduction in the symptoms of mitochondrial disease.

The aim of this study is to investigate if the same B vitamin, Nicotinamide Riboside, can increase energy production and reduce symptoms in humans with mitochondrial disease.

The study will consist of two parts:

Part 1: Participants will be given a single oral dose of Nicotinamide Riboside and the levels of NR in their bloodstream will be measured at regular intervals. This will involve a single overnight stay and simple blood tests.

Part 2: This requires 6 separate visits from each participant. Each participant will undergo a series of standard tests including a muscle biopsy and an MRI scan, then they will take a course of Nicotinamide Riboside (twice daily for 4 weeks). After 4 weeks of treatment, the participants will undergo the same tests again to see if there have been any changes in response to the treatment.

Read the detailed description

Mitochondria are the primary source of energy within the cell, in the form of adenosine triphosphate (ATP). Mitochondrial ATP production is tightly regulated according to the energy requirements of the cell, but little is known about the underlying control mechanisms. This is important for the understanding of the biology of cell energetics and also relevant for patients with rare mitochondrial diseases where it has been proposed that inducing mitochondrial proliferation (biogenesis) might be an effective treatment. However, before embarking on therapeutic studies, it is essential to develop our understanding of the homeostatic mechanisms. Patients with mitochondrial diseases show an enhanced capacity for mitochondrial proliferation, and therefore provide an ideal platform to study mitochondrial homeostasis in vivo in man. The aim of this study, therefore, is to investigate the homeostatic mechanisms in this group of individuals because we are most likely to see an effect in this context.

Nicotinamide riboside (NR), a NAD+ natural precursor, boosts the PGC1α-dependent mitochondrial biogenesis pathway, leading to increased transcription of genes of the oxidative phosphorylation and improved motor performance of myopathic mice. This study is an open-label experimental medicine study using NR with the primary aim of determining whether there is mechanistic link between mitochondrial biogenesis and physiological function in humans with a similar mitochondrial disease.

This project consists of two studies, carried out in series. Both will investigate patients with a clinical and genetic diagnosis of:

  1. Progressive external ophthalmoplegia (PEO) plus exercise intolerance/fatigue, caused by a single deletion of mitochondrial DNA or ii. Mitochondrial disease caused by the m.3243A>G mutation in mitochondrial DNA

Study 1: a 24 hour study before the experimental intervention, to confirm bioavailability of NR at a dosage within the range of a published study.

Patients (n=5) will be invited to the CRF for an overnight stay. If applicable, a urinary pregnancy test will be carried out before any study procedures commence. A baseline blood sample will be taken before administration of the supplement. Oral NR will be administered at a dosage of 10mg/kg -, and blood samples will be drawn at 30 mins,1, 2, 6, 12 and 24 hours post administration. These samples will be used for measurement of NR/NAD+ levels in blood at the relevant time points and ensure these are at expected levels before proceeding to experimental intervention.

Study 2: a 4-week study to determine whether NR induces mitochondrial biogenesis and affects mitochondrial function in patients with mitochondrial disease.

Patients (n=10) will undergo measurements of mitochondrial biogenesis and physiological activities. Oral NR will be administered at a dosage of 10mg/kg b.i.d, (taken twice daily, after food) and patients will be asked to return weekly for standard observations and to provide a blood sample. After 4 weeks of NR administration, patients will return for a repeat measure of the mitochondrial biogenesis parameters and physiological activities
