Edaravone (Radicava) approved to treat MND in USA – what does this mean for people with MND in the UK

On Friday 5 May in America, the FDA, the organisation that approves drugs, announced that they’d granted a licence for the drug known as a Edaravone (to be marketed as Radicava ) for the treatment of MND. It’s extremely exciting news and we’re currently working out what this means for people with MND in the UK. Below is more information on what we know so far:

What is this drug and what does it do?
In clinical trials, Edaravone has been shown to slow the progression of MND potentially helping people preserve function longer. Some of the clinical trial results have shown that Edaravone only works on a subset of people at the early stages of the disease – we are seeking to confirm this.

Edaravone is an antioxidant drug that works by mopping up ‘free radicals’ in the body. Our cells have quite effective ways of dealing with free radicals, but these ‘cellular defences’ become less and less efficient with age.

As we age, our energy production processes lose efficiency, causing a ‘double-whammy’ of not only more free radicals being produced, but also less effective ways of dealing with them. When neurones are damaged, as happens with neurodegenerative diseases, then everything gets exacerbated even further, leading to a vicious cycle of events.

It’s a bit like sparks escaping from a campfire – if there are too many sparks and you don’t keep an eye on things, you could end up with the forest ablaze. There’s more information on earlier post on our research blog.

How would people take Edaravone?
Edaravone is administered intra-venously (IV). People with MND would receive the drug every day for two weeks, then take a break for two weeks. A company called Treeway are currently developing an oral preparation of the drug.

What is the process for licencing this in Europe?
We are in contact with Mitsibushi-Tanabe in the USA and have asked them to connect us with their European office in order to understand their plans for licensing in Europe.

The company will have to apply to the European Medicines Evaluation Agency. The drug has already been registered with EMEA as an orphan disease candidate, which means that any licensing application will be fast-tracked. EMEA approval, however, does not ensure UK approval and the drug would need to be approved by the Medicines and Healthcare Regulatory Agency. New medicines are usually also reviewed by the National Institute for health and Care Excellence, which makes recommendations on the cost-effectiveness to the NHS. There is a process for joint MHRA-NICE review which the company will doubtless pursue.

The licencing process does take time, so the company could also apply through the Government’s Early Access to Medicines scheme, which aims to make a drug available where marketing authorisation is not yet approved and there is a clear unmet medical need.

Where can I find out more?
More information on Edaravone is available on the ALS Association website. More information on clinical trials in general is available on our website our website and in our research information sheet. As we learn more about the developments of the drug we will keep everyone updated.

Funding for Gut-sy MND research announced

Yesterday the Reta Lila Weston Trust announced that they will be funding Dr Nikhil Sharma and colleagues at the Leonard Wolfson Experimental Neurology Centre (LWENC) to investigate whether the bacteria that live in our guts could alter the progression of MND. The grant is for £1.2 million over a period of four years. The LWENC is run jointly by the National Hospital for Neurology and Neurosurgery (NHNN) and University College London (UCL).

Incredibly, researchers have found a link between the bacteria that live in our guts and important cells called microglia. We know that microglia help regulate the function of the motor neurones. This study aims to find out whether the balance of gut bacteria in MND could be linked to changes in microglia. Continue reading

New research projects agreed to help improve palliative and end of life care

Today we announced the results of an exciting new funding partnership with Marie Curie. Together we will be co-funding three research grants that help to answer some questions that people with MND identified as a priority for end of life care research. This is the first time that the MND Association and Marie Curie have worked together with a joint funding call. Each organisation has committed an equal amount of money to the funding of these projects, a total cost of £450,000 over the duration of the projects.

Focus on the research presented in posters in Dublin

Over 100 talks were given at this month’s International Symposium on ALS/MND in Dublin. There were also over 450 posters of research being presented too. Time in the conference programme was allocated on Wednesday and Thursday evening (day 1 and day 2 of the 3 day conference) to visit the posters – you might think that scheduled at the end of the day they would be less well attended – but not a bit of it! It was an extremely loud and buzzy part of the conference.

Below is a brief round-up of some of the posters that caught my eye. Continue reading

Prize winning posters in Dublin

As well as all the networking, debate and new information being shared, the International Symposium on ALS/MND is also a time to celebrate achievements by the giving of awards. The Biomedical and Clinical poster prizes are an opportunity to recognise and celebrate the excellent research and clinical practice being conducted by those early in their career.

Now in its fourth year we hope that the poster prizes will help give the winners career a boost, and give them the encouragement and motivation to continue in MND/ALS research.poster-prize-winners-low-res This year the Panel selected an international group of winners: Dr Albert Lee from Australia and Elsa Tremblay from Canada were jointly awarded the Biomedical poster prize and Ruben van Eijk from The Netherlands won the Clinical poster prize. Each winner received a certificate and a glass engraved paperweight.

The prize winning research ranged from understanding the consequences of a newly discovered gene mutation linked to MND, to why the junction between nerves and muscles is one of the earliest signs of motor neurone damage, to a new statistical analysis to make clinical trials quicker and more efficient. Below I’ve explained more about the research that the winners presented. Continue reading

What causes MND – an update from Dublin

What causes MND is the question that so many of us want to know. For the majority of people with MND we know that it is caused by a combination of many environmental, genetic and lifestyle factors, that gradually tip the balance towards someone developing MND. In the very first talk of the 2016 International Symposium on ALS/MND Joel Vermeulen from The Institute of Risk Assessment Sciences at Utrecht University in The Netherlands gave us an update on research underway to understand the environmental and lifestyle contributions to why people develop MND. Continue reading

Welcome to the International Symposium on ALS/MND in Dublin

Today marks the beginning of the next year in MND research around the world, or at least it certainly feels like that! It is the first day of the three day, international MND research conference that the MND Association of England, Wales and Northern Ireland is immensely proud to organise. Continue reading

New genetic discoveries tell us more about what causes MND – Part 2

Two sets of MND genetic results were published yesterday. One of these results was about the importance of a new gene called NEK1. The second highlighted the role of gene C21orf2 in MND – we wrote an article about this yesterday. Both sets of results were published in the prestigious journal Nature Genetics.

What are the results and what do they tell us?

Researchers found that variations in the NEK1 gene contribute to why people develop the rare, inherited form of MND. Variations in the NEK1 gene were also found to be one of the many factors that tip the balance towards why people with no family history develop MND.

NEK1 has many jobs within motor neurones including helping keeping their shape and keeping the transport system open. Future research will tell us how we can use this new finding to target drugs to stop MND. Continue reading

New genetic discoveries tell us more about what causes MND – Part 1

Today some exciting news about the genetics of MND was published in the scientific journal Nature Genetics. The results come in two research papers published in the same issue of the journal.

This blog post discusses the results of the first of these papers for which King’s College London based Professor Ammar Al-Chalabi was one of the leading researchers. A post on the second paper will follow later.

Here we’ve given an overview of what the researchers have found, what it means for people with MND and how the analysis was conducted. You can read a more detailed explanation of the research results from the King’s press release. Continue reading

Motor neurone signalling and the effects of RNA in MND

Dr Pietro Fratta completed his first MRC-MND Association Clinical Research Training Fellowship in 2014. Last year he was awarded a new £1.16 million Clinician Scientist Fellowship to continue his research at University College London, studying the earliest physical changes that affect motor neurons in MND (our reference 946-795). Our contribution to this four year research fellowship is £280,000.

As his first Fellowship progressed, Dr Fratta became more interested in the field of RNA biology, where he is rapidly establishing himself as an expert. His latest project aims to see whether RNA plays a pivotal role in the earliest signs of cellular damage that occur in MND.

RNA is the cell’s copy of our genetic material known as DNA; Dr Fratta is hoping to establish if the transport of RNA molecules along the nerve fibres is impaired and if so, whether there are particular versions of RNA that are particularly important for motor neurone health and survival.

Several lab studies have shown that the process of transporting things up and down the motor neurones is impaired long before the physical signs of damage are seen. His research will seek to find out what RNA molecules are present in both the cell body of the motor neuron and the nerve fibres. Continue reading
