This week a new clinical trial was registered which caught our attention here at the SoPD HQ. It is being sponsored by a small biotech called Neuraly and involves a drug called NLY01.
NLY01 is a GLP-1R agonist – that is a molecule that binds to the Glucagon-like peptide-1 receptor and activates it. Other GLP-1R agonists include Exenatide (also called Bydureon) which is also also about to start a Phase III clinical trial in Parkinson’s (Click here to read a previous SoPD post about this).
There is a lot of activity in the Parkinson’s research world on GLP-1R agonists at the moment.
In today’s post, we will discuss what a GLP-1R agonist is, what we know about NLY01, and what the new clinical trial involves.
Every week there are new clinical studies being announced for Parkinson’s.
This week one particular newly registered clinical trial stood out. It involves a small biotech company Neuraly (which is owned by parent company D&D PharmaTech).
What is a GLP-1R agonist?
The clinical testing new compounds is horrifically slow. There is simply no easy way to word it. From lab bench to regulator approval, we are currently looking at a process which will take at least a decade.
The repurposing of clinically available treatments has shortened this process, but there are a limited number of drugs that can be repurposed, and the periods of time between clinical trials is still too long.
Acknowledging this situation, we can do one of two things: Accept the circumstances and carry on doing things the way we have always done it (hoping that it will be different next time – a la Einstein’s definition of insanity),… OR we can try to change it.
In today’s post, we will discuss an interesting project that is seeking to do the latter.
The guy at the podium (and in the upper left inset) is Barry Chandler.
A few months ago, Barry came to me and asked “What can I do to help?”
And I replied by asking “What do you do?”
Two things you need to know about Barry:
- He was diagnosed with young onset Parkinson’s 6 years ago, and
- He is a very well connected guy.
VERY well connected!

By day, Barry works in the city of London as a DevOps practitioner (that was a new one for me too – “a combination of cultural philosophies, practices, and tools that increases an organization’s ability to deliver applications and services at high velocity“). But in the evenings and on weekends, Barry is an events co-ordinator.
And these two worlds merge nicely in the form of a meetup group that Barry runs, called “SEAM”.
What is SEAM?
This week a biotech company called Voyager Therapeutics provided an update regarding a gene therapy approach for people with severe Parkinson’s.
Gene therapy is an experimental therapeutic approach that involves inserting new DNA into cells using a virus. The introduced DNA can help a cell to produce proteins that it usually wouldn’t produce, and this can help to alleviate the motor features of Parkinson’s.
In today’s post we will discuss what gene therapy is, what Voyager Therapeutics is trying to do, and outline what their update reported.
There are 4 phases to the clinical trial process of testing new treatment for use in humans:
- Phase I determines if a treatment is safe in humans (this is conducted in an ‘open label’ manner)
- Phase II ‘double blindly’ assesses in a small cohort of subjects if the treatment is effective
- Phase III involves randomly and blindly testing the treatment in a very large cohort of patients
- Phase IV (often called Post Marketing Surveillance Trials) are studies conducted after the treatment has been approved for clinical use
(‘Open label’ refers to both the investigator and the participants in a study knowing what treatment is being administered; while ‘double blind’ testing refers to studies in which the participants and the investigators do not know whether the participant is receiving the active treatment or an inert control treatment until the end of the study).
Based on the successful completion of their Phase I clinical trials for their gene therapy treatment called VY-AADC (Click here to read more about this), Boston-based biotech firm Voyager Therapeutics approached the US Food and Drug Administration (FDA) with the goal of shifting their clinical trial programme into Phase II testing.

At the end of each year, it is a useful practise to review the triumphs (and failures) of the past 12 months. It is an exercise of putting everything into perspective.
2017 has been an incredible year for Parkinson’s research.
And while I appreciate that statements like that will not bring much comfort to those living with the condition, it is still important to consider and appreciate what has been achieved over the last 12 months.
In this post, we will try to provide a summary of the Parkinson’s-related research that has taken place in 2017 (Be warned: this is a VERY long post!)
The number of research reports and clinical trial studies per year since 1817
As everyone in the Parkinson’s community is aware, in 2017 we were observing the 200th anniversary of the first description of the condition by James Parkinson (1817). But what a lot of people fail to appreciate is how little research was actually done on the condition during the first 180 years of that period.
The graphs above highlight the number of Parkinson’s-related research reports published (top graph) and the number of clinical study reports published (bottom graph) during each of the last 200 years (according to the online research search engine Pubmed – as determined by searching for the term “Parkinson’s“).
PLEASE NOTE, however, that of the approximately 97,000 “Parkinson’s“-related research reports published during the last 200 years, just under 74,000 of them have been published in the last 20 years.
That means that 3/4 of all the published research on Parkinson’s has been conducted in just the last 2 decades.
And a huge chunk of that (almost 10% – 7321 publications) has been done in 2017 only.
So what happened in 2017? Continue reading
This week a biotech company called Voyager Therapeutics announced the results of their ongoing phase Ib clinical trial. The trial is investigating a gene therapy approach for people with severe Parkinson’s disease.
Gene therapy is a technique that involves inserting new DNA into a cell using a virus. The DNA can help the cell to produce beneficial proteins that go on help to alleviate the motor features of Parkinson’s disease.
In today’s post we will discuss gene therapy, review the new results and consider what they mean for the Parkinson’s community.
On 25th August 2012, the Voyager 1 space craft became the first human-made object to exit our solar system.
After 35 years and 11 billion miles of travel, this explorer has finally left the heliosphere (which encompasses our solar system) and it has crossed into the a region of space called the heliosheath – the boundary area that separates our solar system from interstellar space. Next stop on the journey of Voyager 1 will be the Oort cloud, which it will reach in approximately 300 years and it will take the tiny craft about 30,000 years to pass through it.

Where is Voyager actually going? Well, eventually it will pass within 1 light year of a star called AC +79 3888 (also known as Gliese 445), which lies 17.6 light-years from Earth. It will achieve this goal on a Tuesday afternoon in 40,000 years time.

Remarkably, the Gliese 445 star itself is actually coming towards us. Rather rapidly as well. It is approaching with a current velocity of 119 km/sec – nearly 7 times as fast as Voyager 1 is travelling towards it (the current speed of the craft is 38,000 mph (61,000 km/h).
Interesting, but what does any of that have to do with Parkinson’s disease?
Well closer to home, another ‘Voyager’ is also ‘going boldly where no man has gone before’ (sort of).
