In November 2018 the Home Office released a draft Guideline scope for Cannabis-based products for medicinal use in which they announced that specialist doctors (like consultant neurologists) on the Special Register of the General Medical Council will be able to prescribe cannabis-based medicinal products to some patients. Before this, the only cannabis-based medicines licensed for use in the UK were nabiximols (Sativex), used as a treatment for spasticity (where muscles are continuously contracted, causing stiffness or tightness of the muscles, interfering with normal movement and speech), in multiple sclerosis (MS).Read More »
There has recently been a flood of news stories on the outcomes of the Australian Phase 1 clinical trial investigating Copper ATSM (CuATSM) which is a small man-made compound that can selectively deliver copper to cells. The results were first presented at our International Symposium in Glasgow back in December.
MND is a terrible disease and anyone affected by it is looking for good news. We really hope that CuATSM will provide a new treatment for MND that is going to have a positive effect on people’s disease progression.
However, CuATSM is not yet at a stage where a clinician can prescribe it as a treatment. Drug development is a long journey, where any drug has to pass important rigorous checks before approval as a medicine. This trial is an important ‘first’ in the drug development process.
This blog is part of the ‘Highlights from Glasgow’ collection of articles, where you can read about the content of some of the talks and posters presented at the 29th International Symposium on ALS/MND.
In the Clinical trials and trial design (4B) session we heard from two speakers looking at ways to improve current design of clinical trials. In his plenary talk, Mahesh Parmar (C20) provided his perspective on the necessity of changes from his experience working on cancer trials, highlighting that any efforts to improve clinical trials should be focused on Phase 3 where the most money and time is spent. One solution that stuck with a lot of clinicians attending Prof Parmar’s talk was the design used in the STAMPEDE trial, a large clinical trial assessing effectiveness of new treatments for people affected by prostate cancer, which has been running since 2005. The innovation of this approach is the ongoing protocol that allows to test multiple treatments within the same established clinical trial, allowing new drug candidates to be tested (relatively) straight away, avoiding the creation of a brand new clinical trial. This design improves efficacy of testing new treatments, systematic approach to testing, and access to a large pool of participants who could take part in multiple treatment trials over time.
Brian Dickie, the Director of Research Development at the MND Association said: “Prof Parmar’s presentation generated a lot of interest amongst clinicians who are regularly involved in MND trials and there was a strong feeling that this is the direction that we need to be taking with MND as it could increase the efficiency and reduce the cost. That said, it will take a while to put the building blocks in place and we certainly wouldn’t want to hold up trials that are already in advances stages of planning, so I would expect to see a gradual introduction of changes to trials design over the coming years.”
In their official press release published on 21 November 2017, Cytokinetics Inc. announced that they will not be continuing work on tirasemtiv after disappointing results in the latest Phase 3 clinical trial. The trial, known under the acronym ‘VITALITY-ALS’, tested whether the drug has a beneficial effect on the breathing function and muscle strength of people with MND. This is very unfortunate news for everyone affected by the disease, however, Cytokinetics are already testing another compound with the hope that this will be more effective and better tolerated than tirasemtiv.
Tirasemtiv is a drug that aims to improve quality of life of people living with MND by increasing strength of their skeletal muscles (controlling body motion and posture) and therefore postponing muscle fatigue. It compensates for the missing nerve signal from a motor neurone to a muscle that instructs it to contract. Tirasemtiv activates a protein called troponin by increasing its sensitivity to calcium, which is crucial for muscle contraction.Read More »
There is recent evidence to suggest that Human Endogenous Retroviruses (HERVs) may be involved in amyotrophic lateral sclerosis (ALS). HERV-K has been directly linked to motor neurone damage and has been found in the brain tissue of patients with ALS.
The MND Association recently awarded a small grant to fund part of the ‘Lighthouse Project’ which is investigating the safety and any beneficial effects of an antiretroviral drug on ALS symptoms.Read More »
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.Read More »
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.Read More »
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:
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. 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.Read More »
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.
The guidelines are divided into sections:
- Preclinical studies
- Study design and biological and phenotypic heterogeneity
- Outcome measures
- 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.
Thank you very much for your help.
