NutrInD: Nutrition In Duchenne Study

Assessing Energy Expenditure, Dietary Intake and Body Composition in People with Duchenne Muscular Dystrophy.

Hub Summary

The purpose of this study is to collect information about the nutritional needs of people with Duchenne Muscular Dystrophy (DMD).

Proper nutrition is very important for children, adolescents, and young adults with DMD. Excessive weight gain is a very common problem which leads to obesity. Many factors contribute to weight gain. These include steroid treatment, excess calorie consumption, less physical activity, and lower muscle mass. Extra weight can make walking and transferring more challenging. Obesity may lead to high blood pressure, and affect heart and lung function. Adequate eating habits are also valuable in supporting growth, bone and gut health, and helping the body process nutrients from food.

A better understanding of the nutritional needs of young people with DMD can help improve their overall well-being. So far, very little is known about this.

We hope that the findings of this study will help us create specific nutrition-related guidance for young people with DMD.

Genethon- Microdystrophin Gene Therapy (GNT-016-MYDF)

GNT-016-MYDF: A phase I/II/III study with a dose determination part followed by an efficacy and safety evaluation of selected dose part and then by a long-term follow-up part in ambulant boys aged 6 to 10 years with DMD

Hub Summary

GNT0004 is a recombinant adenovirus-associated viral (AAV) vector gene therapy, composed of an AAV8 serotype capsid containing a sequence-optimised gene for a human microdystrophin.

Duchenne muscular dystrophy (DMD) is a neuromuscular disorder caused by dystrophin gene mutations leading to absence (almost absence) of functional dystrophin, a key protein that prevents muscle cell damage during physiological contractions. Conceptually, adding a functional copy of the gene to muscle cells would, in principle, treat the underlying cause of the disease. However, there are two main obstacles to overcome to achieve this. First, a vehicle (vector) is needed to transport the functioning gene to target muscle cells. AAV capsids are frequently used as the vehicle to transport genes in other gene therapy products. The specific type of AAV capsid in GNT0004 is called AAV8. The second obstacle to overcome is the size of the dystrophin gene. It is one of the largest genes in our bodies and because it is so large it cannot fit inside the AAV capsid. To address this obstacle, the Genethon research group has developed a miniaturized but functional version of dystrophin (Microdystrophin).

The principle of GNT0004 is to deliver an optimized microdystrophin protein to target tissues (heart and skeletal muscles) in DMD subjects. It is expected to significantly delay or slow down the progression of the disease in humans in a similar manner to how it has shown to be able to do this in animal models with the disease.

In order to help GNT0004 reach muscles throughout the body, GNT0004 will be given as a one-time intravenous (IV) infusion.

NS Pharma - RACER53-X

Study to Assess the Safety and Efficacy of Viltolarsen in Ambulant Boys With DMD (RACER53-X)

Hub Summary

This is a Phase 3, multi-center, open-label extension study in ambulant boys with DMD who have completed the 48-week treatment period of either viltolarsen or placebo in Study NS-065/NCNP-01-301.

The dystrophin gene has 79 pieces called exons. These link together to form a code which instructs the body to make dystrophin. If there is a fault, as in DMD, the sequence is broken and the code cannot be read. Exon skipping drugs complete the sequence and leads to a shortened dystrophin being produced that still contains the important pieces of this molecule.

Study Number: NCT04768062

Hydrotherapy in DMD

Hydrotherapy for health in boys and adolescents with Duchenne muscular dystrophy

Hub Summary

Exercise is very important for young people to help keep them healthy. It could be as important for children and young people who have a muscle disease, like Duchenne muscular dystrophy (DMD). Hydrotherapy is a form of exercise that involves doing exercises with a physiotherapist in a heated swimming pool.  

We are running a study to try to better understand the impact that hydrotherapy might have on young people with DMD, and whether or not it offers any benefits to their physical and mental wellbeing. We will use the findings from the study to develop simple guides to advise on activities and exercise while in the water. 

D-Brain

Defining outcome measures for behavioural and emotional problems in dystrophinopathies

Hub Summary

Research has shown that in a proportion of individuals with DMD and BMD, there might be some involvement of how the brain works. This can result in some individuals having a degree of learning difficulties, behavioural or psychological difficulties.

To investigate this, we are conducting a large cohort study to identify which part of the DMD gene is responsible for the development of these complications and help us further define and develop robust clinical assessments which will outline psychological profiles for DMD and BMD patients.

The study will involve two consecutive visits, which will include assessment of cognition (thinking and problem solving) and behaviour (inattention, anxiety, hyperactivity, etc.) . These two visits will be repeated after 6 months. For those interested there is also the possibility of participating in the MRI component of the study.

This study will cover your travel expenses and will provide you with detailed feedback on your son’s potential difficulties that can be used to receive educational support, to get a referral for local authorities or for your own personal use as it might give you some useful insights about your son’s behaviour.

D3 Creatine

Changes in muscle mass using the D3-creatine dilution method and function in DMD

Hub Summary

This study will use a new, non-invasive method of measuring muscle mass in patients with Duchenne muscular dystrophy. It is jointly funded by Duchenne UK, Muscular Dystrophy Association and Parent Project Muscular Dystrophy.

Participants will attend 3 6-monthly study visits over the course of the study in line with regular clinic visits. At the visit, participants will drink a small amount of D3-creatine, which can be used to measure changes in the muscle by testing urine samples. There are no risks involved with drinking the solution - it has been tested in children and adults of all ages, as well as boys with DMD, with no adverse events being recorded so far.

During the visit, the participant will also undergo functional tests, including the NSAA (North Star Ambulatory Assessment), upper limb assessment and timed tests. This will help to demonstrate whether changes in muscle mass will be reflected in changes in function.

RIM4DMD

Rimeporide in patients with Duchenne muscular dystrophy

Hub Summary

Patients with DMD have imbalanced levels of calcium and sodium in their muscle cells, this is thought to play a key part in the damage which occurs to muscles. This study is evaluating the safety and tolerability of rimeporide. Rimeporide is a drug which works by inhibiting the movement of sodium and calcium from muscle cells. Inhibition of this mechanism has been proven to be efficient in preventing inflammation and fibrosis (muscle damage) in animal models. In addition to the preventative effect on muscle damage, rimeporide was also shown to be cardioprotective. 

This investigational treatment could have no restriction on age and is not mutation specific, meaning it could treat all patients with DMD. This phase 1b study will examine Rimeporide in patients aged 6 to 14 years.

Study Number: NCT02710591

PTC Ataluren Phase 3

Phase 3 Extension study of Ataluren (PTC124) in Patients with Nonsense Mutation Dystrophinopathy

Hub Summary

DMD is caused by a mutation in the gene which produces dystrophin. Dystrophin functions to maintain muscle structure and function. The loss of dystrophin in DMD leads to muscle weakness and loss of ambulation. A nonsense mutation is a specific type of mutation which is the cause of DMD in 10-15% of patients.

Ataluren is a drug designed to make the body's machinery less sensitive to nonsense mutations. This phase 3 trial is designed to assess the long-term safety of Ataluren in boys with nonsense dystrophinopathies. The study will also assess changes in clinical measures such as muscle function and pulmonary function.

Study Number: NCT03039686

Summit- Ezutromid (PhaseOut DMD) [TERMINATED]

Please note the development of this drug was stopped after this trial failed to reach its objectives.

Hub Summary

This phase 2 clinical trial is designed to assess the activity and safety of Utrophin modulation in patients with DMD with SMT C1100 (Ezutromid). Ezutromid is an orally administered small molecule utrophin modulator.

Utrophin is a bodily protein which is structurally and functionally similar to dystrophin. Utrophin is naturally produced in the early stages of muscle development but is turned off as muscle fibres mature and dystrophin increases to perform the same role. Utrophin modulation aims to maintain the production of utrophin to compensate for the absence of dystrophin in patients with DMD.

This 1 year study has an optional extension phase. 

Study Number: NCT02858362
