New Research May Lead to the Development of Compounds to Correct Mitochondrial Dysfunction in CMT

Charcot-Marie-Tooth (CMT) disease is an inherited neuromuscular disorder that leads to a gradual loss of motor neurons and eventual paralysis. The condition is caused by genetic mutations that disrupts cells' mitochondria. No drugs are available to slow or stop the progression of the disease, which affects nearly 3 million people worldwide.

Scientists at Washington University School of Medicine in St. Louis and Stanford University, report that they have designed small compounds that have the potential to correct the mitochondrial dysfunction that leads to CMT. The team designed the compounds after work in mouse cells revealed a new understanding of the 3-D structure of a key protein that is disabled in the mitochondria of patients with the disease.

The mitochondrial protein the researchers studied is called mitofusin 2. Mitofusin 2 governs whether two mitochondria are able to tether to each other and then fuse, exchanging genetic information, which is thought to be important for maintaining healthy mitochondria and therefore healthy tissues.

Once the researchers understood how mitofusin 2 changes shape, they were able to design small peptides that interact with the protein and drive it toward either an active or inactive state. One of the small molecules, dubbed GoFuse, forces mitofusin 2 into its active, healthy state, which encourages tethering and the resulting mitochondrial fusion. The hope is that GoFuse, or a similar molecule, could encourage the mitochondrial tethering and fusion that is missing in CMT disease. If such tethering could be restored, it could prevent or delay the loss of motor neurons that gradually paralyzes many patients with this genetic disorder.

14th TACT Meeting - 3 Applications Reviewed (Miami, USA)
back to top    

The TREAT-NMD Advisory Committee for Therapeutics (TACT) recently held its 14th meeting (29-30th October 2016) in Miami, USA. The TACT core group gathered on Friday 28th to discuss the running of the committee which continues to attract more interest from applicants. Also on the agenda was the important expansion of TACT to cover therapy development in amyotrophic lateral sclerosis (ALS) - Applications in this area are now being encouraged.

Saturday and Sunday brought together 19 multidisciplinary members of the TACT committee as well as the secretariat. We also welcomed 2 observers from patient advocacy groups who wanted to learn more about the successful model that TACT follows. During the meeting the TACT members discussed 3 proposals submitted by industry applicants. Within 6 weeks of the meeting the committee will generate a report providing recommendations to these applicants and a non-confidential summary of each will be published on the TREAT-NMD website by the end of December.

The proposals reviewed on this occasion were:

1. VAL-0620 Muscle-targeted enzyme replacement therapy - Deborah Ramsdell, Valerion Therapeutics LLC, USA. Lead reviewer, John McCall

2. Utrophin modulation as a potential treatment for Becker muscular dystrophy - Jon Tinsley, Summit Therapeutics, UK. Lead reviewer, Anna Mayhew

3. Tideglusib, an inhibitor of the kinase GSK3β - Mike Snape, AMO Pharma Ltd, UK. Lead reviewer, Cristina Csimma

Plans are now underway for the next meeting which will be held from 29-30 April 2017 in Edinburgh, UK. Interested applicants should contact the TACT coordinator, Cathy Turner as soon as possible to discuss submission in time for this meeting.

 
 
 
 
Workshop on Spinal Muscular Atrophy
back to top    

On 11 November 2016 the European Medicines Agency (EMA), SMA Europe and the TREAT-NMD network held a one-day workshop to discuss, support and advance the development of therapies for the treatment of spinal muscular atrophy (SMA). The workshop took place at the EMA in London.

The workshop brought together key stakeholders from Europe and USA – patients, doctors, industry representatives, researchers and regulators, to discuss the latest scientific developments in the area of SMA and ways of developing therapies for the treatment of SMA. The programme for the day was divided into three sessions that covered a number of topics including:

 

  • An overview of the disease
  • The pharmacology of the molecules under investigation
  • Natural history data
  • Clinical outcome measures
  • Potential use of biomarkers in drug development

 

Patient perspective on clinical trials and drug development was also presented. The importance of patients and carers’ input and involvement in the development of clinically meaningful outcome measures and how these are used in regulatory discussions and decisions was underlined throughout the day.

The workshop allowed the exchange of knowledge and perspectives among different parties involved. It is hoped that the discussion around the meaningfulness of the data for the evaluation of the therapeutic approaches in the treatment of SMA will be useful for further work on the regulatory guidelines on medicinal products for SMA. A briefing paper was produced in preparation for the meeting and to help with the discussions on the day of the meeting. The document is available on the TREAT-NMD website here.

 
 
 
 
cTAP Announces Two Research Publications Categorizing
and Predicting Disease Progression in
Duchenne Muscular Dystrophy
back to top    

The Collaborative Trajectory Analysis Project (cTAP), a public-private partnership to accelerate data science solutions to critical problems in drug development for Duchenne Muscular Dystrophy (DMD), announced the publication of two research studies with important implications for the design of effective clinical trials.

All patients with DMD eventually lose the ability to walk, but the rate at which ambulatory function declines can vary greatly between patients. This variability can cloud interpretation of clinical trials making it difficult to discern whether or not a drug is effective. The published studies announced here explain approximately half of the variability in disease progression in DMD, more than double that explained previously with conventional analyses. “Without this understanding of the natural clinical progression of the various genetic causes for DMD, it would be extremely difficult to design the clinical trials or choose the appropriate endpoints necessary to develop novel drugs to use for DMD,” said Dr. Edward Kaye, President, CEO and Chief Medical Officer of Sarepta Therapeutics. “cTAP is one of the best examples of international academic collaboration that has advanced the clinical understanding of Duchenne Muscular Dystrophy.”

cTAP has connected leading clinical experts in DMD, drug developers and analytical experts with the shared goal of improving clinical trials in DMD by learning from patient data. The two published studies used statistical methods to quantify and predict disease progression in DMD, drawing from a growing database of more than 1,000 boys with DMD that, in total, includes functional assessments at more than 10,000 clinic visits.

Professor Eugenio Mercuri, a world-leading expert in DMD at the Pediatric Neurology at the Università Cattolica del Sacro Cuore, Rome, Italy, pioneered the collaborative access to registry data in DMD that made these studies possible. “As a first step, we wanted to quantify the different rates of disease progression in different patients,” said Mercuri. Published in the September issue of Neuromuscular Disorders, the study by Mercuri and his colleagues identified statistically distinct groups of patients who had similar trajectories of ambulatory function over time; classifying patients into these groups explained more than half of the variability in trajectories of disease progression.

Building on these findings, a second study led by DMD expert Professor Nathalie Goemans, head of the Neuromuscular Reference Center for Children at the University Hospitals in Leuven, Belgium, was published in PLoS One. Goemans and her colleagues developed a prediction model for one-year changes in ambulatory function using a composite of patient characteristics and functional measures. The prediction model explained more than twice as much variability in ambulatory outcomes compared to patient measures that have been used to define eligibility for DMD clinical trials.

Interview with New EC member Andoni Urtizberea
back to top    

1. Please tell us about your role / organisation / background

I trained in Paris as a specialist in pediatrics and in physical medicine & rehabilitation (PMR). I then joined the AFM-Téléthon serving as medical director for many years and as General Delegate of the Institut de Myologie in Paris for a couple of others. Around that time, I became the scientific director of the European Neuromuscular Center (ENMC), taking over from my beloved mentor Alan EH Emery.

I then briefly held a professorship in Garches Hospital (APHP) before getting back to my native land (the Basque Country), in order to be a full-time consultant at Hendaye Hospital, where I currently occupy several positions:

- for 30% of my time, I still head the Hendaye branch of the GNMH (Garches-Necker-Mondor-Hendaye) neuromuscular center of excellence driven by APHP (Assistance Publique Hôpitaux de Paris). More precisely, I diagnose and follow up outpatient neuromuscular patients. Additionally, our hospital (Hendaye) provides respite care for the most debilitated patients.

- since 2015, half of my time is devoted to co-coordinating, together with Prof. Jean Pouget (Marseille), the French neuromuscular network called FILNEMUS (Filière Nationale de Santé Neuromuscular).

-  the remainder (20%) is spent as a freelance consultant both for the industry and for various foreign institutions (notably in the Middle-East). In that context, I'm responsible for many educational events such as the well-known Summer School of Myology

2. How did you become a TREAT-NMD Executive Committee member and what does the role involve?

I remember having been a strong supporter of the early initiative taken by Françoise Salama and many other patient representatives, about having a special European call in the field of NMD, notably for promoting cutting-edge therapies.

I strongly believed and still believe in the added value of uniting forces at the European level. What Kate Bushby and her colleagues have achieved in the field for the past ten years is an enormous contribution, not only for physicians and scientists but also for caregivers and patient organizations.

For many years, and due to several personal constraints, I could not commit myself to the governance of TREAT-NMD Alliance. Meanwhile, I accepted to be part of the Task Force and to serve as a kind of roving ambassador of the Alliance. This year, FILNEMUS, in a move to establish closer links with the TREAT-NMD Alliance, asked me to apply for the vacant position in the executive committee and supported my candidacy strongly. I accepted with enthusiasm. In addition to be the first Frenchman ever elected in the EC, I also wish to contribute more specfically in the field of education/training. I also share with pleasure, the product of our intensive networking that we and others have done in many parts of the world (Middle-East, Latin America, Russia, Indian subcontinent).

3. What do you see as the biggest challenge to the Neuromuscular field (in relation to translational research)

Diagnostic procedures will simplify over time and get cheaper and cheaper enabling better and equitable access to accurate labelling of NM diseases. My main concern is actually about standardization of care. It is still a formidable challenge in many countries where I have seen neuromuscular patients as a visiting professor. In my view, awareness, education and training are the key-elements in order to bridge the gap between our Western world and others.

4. Why is TREAT-NMD so important for the field and why should people become a member?

In my opinion, TREAT-NMD Alliance now exerts an undisputed worldwide leadership which is excellent news. It is the best vehicle to network efficiently and not only at the scientific level. Patients and patient organizations can also voice their concerns. There's no better demonstration that stakeholders act best when united.

5. Tell us something about yourself that not many people will know?

I have a real passion for minorities hence my fascination (but not my competence, I confess) in population genetics. My dream is to compile some day personal observations of neuromuscular patients/families belonging to such isolated, often inbred communities. Historically, the Cajuns, the Amish, and the Romas are my favorites but there are plenty of others I am working on (the Bahaïs, the Iakuts, the Aggarwals, the Beduins etc.).

Is this dictated by my eternal unanswered quest about the origins of my ancestors, the Basques? Not impossible. Just ask my psychoanalyst!
