It’s been over a month since the announcement by the FDA of their decision to licence edaravone / Radicava for people with MND in the USA. The speed of the FDA’s decision took the drug company MT Pharma and the MND research community by suprise. It is encouraging that edaravone has been licenced to treat MND after two decades of failed drug trials. Since the FDA announcement the effects of the drug and what it means for people with MND has been extensively discussed and some of the trial data has been published.
This blog is an update on what studies have been done on edaravone and the likelihood of people with MND noticing a beneficial effect if they were to receive it. Continue reading →
Each year, the MND Association dedicates the month of June to raising MND awareness. This year, we focus on the eyes – in most people with MND the only part of their body they can still move and the only way left for them to communicate. Alongside the Association-wide campaign, the Research Development team selected six most-enquired about topics, which we will address through six dedicated blogs.
So far, there is no cure for MND. In the past 22 years, we have only seen approval of two drugs that were either shown to prolong the life of MND patients by several months (riluzole in 1995 in the US) or to slow down symptom progression (edaravone in 2015 in Japan). It is only reasonable that you might wonder ‘what is taking so long?’ or ‘why are there not more drugs available?’.
It is very competitive in the world of medicinal drugs. From thousands of chemical compounds that are gradually eliminated as they go through different stages of drug development, only one makes it near the finish line. This line represents approval for marketing authorisation and there is no guarantee that this ‘top compound’ will actually make it to the end. So let’s have a closer look at the individual stages that a potential drug has to go through in order to be crowned the champion. Continue reading →
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 unexpected 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:
A few months ago we wrote an article about the ALS Clinical Trials Workshop which took place in Virginia, USA. Since then the Guidelines Working Groups have been busy turning the large number of issues debated into a first draft of a new set of guidelines. This is open for comment from 1- 31 August.
Study design and biological and phenotypic heterogeneity
Therapeutic / Symptomatic interventions in clinical trials
Patient recruitment and retention
Different trial phases and beyond – (there are two sections on this)
Within each of these sections, there are many recommendations. The Clinical Trials Guidelines Investigators want to ensure that all interested people and stakeholders have an opportunity to provide input – whether you are a researcher, clinician or person with MND.
This year the Symposium session on clinical trials looked at three drugs and one therapy. Dr Brian Dickie has posted a separate blog on one of these drug treatments – Edaravone.
A summary of the results from the drugs and treatments discussed is below. More information on each of them in detail is later on in this blog.
Ibudilast: This drug was safe and well tolerated in those who were not using non-invasive ventilation. However, these are results from an early stage trial so more research is needed to establish possible long-term benefit.
Methylcobalamin (Vitamin B12 injections): If this treatment is given early (within 12 months of diagnosis) then it showed an effect at increasing survival in a small sub-group of those taking part in the trial. This effect was not seen when the treatment was given further on from diagnosis.
Stem cell therapy: This small, early Phase 1/2 trial was testing the safety of bone-marrow derived stem cell injections into the spinal cord. The researchers found this treatment had no major side effects. Further studies are needed to evaluate the effectiveness and safety of this treatment over the long-term.
Bar a few bacteria usually found hitching a ride on our dental plaque and digestive system, every living cell in the human body needs oxygen. Some cells need more oxygen that others, dependent on much energy they need to produce to function. Neurones are particularly active cells (the brain uses a fifth of all the oxygen consumed by the human body) and motor neurons are amongst the most energy hungry of all.
Unfortunately, the process of producing cellular energy isn’t 100% efficient: a small but constant amount of waste products called free radicals (yep, those things that the beauty product industry bangs on about) can build up in the cells. If not kept in check, they can start to wreak havoc within the cell.
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. Continue reading →
The MND Association’s Director of Research, Brian Dickie explains more about ‘GM6’, also known as ‘GM604’, a drug in development by an American pharmaceutical company Genervon.
The Association funds a wide range of research that leads to new understanding and treatments, which may one day, bring us closer to a cure for MND. We are hopeful that the increasing international research effort into the disease will accelerate the development of an effective treatment for MND. However for non scientists I also fully appreciate how the ‘system’ often seems designed to impede rather than assist this process.
There has been much discussion online about the results of a small scale study of a drug called GM604, or GM6, produced by the American pharmaceutical company Genervon. You can read some general comments about the drug on our website. I’ve written this blog to explain in a little more detail why the research community is cautious about the results.

On 22 September 2014 Neuralstem announced the results from their long-term follow up of three participants who were involved in their initial phase I safety trial. Here’s what the news means and what may be next for Neuralstem’s stem cell treatment.
What is Neuralstem?
Neuralstem is the company behind an innovative neural stem cell treatment for MND. Stem cells are immature cells that have the capability to become any cell in the body. By transforming these in to ‘motor neurones’ it is hoped that they could be used to replace the damaged motor neurones in people living with MND.
Stem cells as a treatment for MND are currently unproven. This means that stem cells have not undergone rigorous testing, by means of a clinical trial, to establish if they are both safe and beneficial in MND. You can find out more about unproven treatments here.
Neuralstem’s stem cell treatment for MND involves several injections of these neural stem cells into the spinal cord of patients. Previous research in animals has shown that these cells make connections with healthy motor neurons and express nerve protecting factors, which could be potentially useful as a treatment for MND.
A number of articles were published in various news sources on 11 July 2014, highlighting how scientists in Sheffield are working towards testing a promising treatment for a rare inherited form of MND caused by the SOD1 gene. Here we write about the research and what it means for people living with MND.
The Sheffield Institute for Translational Neuroscience (SITraN) specialises in research into MND and other neurodegenerative diseases. Recently the institute received an anonymous donation of £2.2 million to help translate their research from the lab to the clinic. This is a huge amount of money into MND research and this donation will enable the researchers to further our understanding of the disease.
We know that approximately 10% of cases of MND are inherited. This means that they are characterised by a strong family history and the disease is caused directly by a mistake in a specific gene. Of these 10% of cases, 2% are caused by the SOD1 gene (meaning that for every 100 cases of MND, 10 cases are inherited and of these, only 2 are directly caused by the faulty SOD1 gene).
Prof Mimoun Azzouz’s research at SITraN was reported in a number of news outlets, highlighting how his research is paving the way to a treatment for a rare form of MND. His research is at a relatively early stage, where he has only just begun investigating the use of a technique known as ‘gene therapy’ in mice affected by the SOD1 inherited form of MND. If the research goes to plan, he will be able to submit a proposal for regulatory approval by August 2015. Continue reading →
Last month the UK Government’s Department of Health announced an Early Access to Medicines Scheme. But, what is this new scheme? and what does it mean for people living with MND?
The drug trial process
The only proven drug to slow progression in MND is riluzole. This is the only drug that has passed all the stages of drug testing – known as clinical trials – and has been shown to be beneficial for people living with MND. Clinical trials are the ‘gold standard’ and are put in place to ensure that a drug is safe and beneficial before it is given to patients.
