The recent documents filed with the U.S. Securities and Exchange Commission by the biotech firm Prevail Therapeutics provides interesting insight into the bold plans of this company which was only founded in 2017.
Even more recent news that the U.S. Food and Drug Administration (FDA) has accepted the company’s Investigational New Drug (IND) application for its lead experimental treatment – PR001 – suggests that this company is not wasting any time.
PR001 is a gene therapy approach targeting GBA-associated Parkinson’s.
In today’s post, we will discuss what GBA-associated Parkinson’s is, how Prevail plans to treat this condition, and discuss what we know about PR001.

The title of this post comes is from a quote by Caterina Fake (co-founder of Flickr and Hunch (now part of Ebay)), but it seemed appropriate.
This post is all about dreaming big (curing Parkinson’s), the struggle to get the research right, and to create a biotech company: Prevail Therapeutics.
What is Prevail Therapeutics?
Prevail is a gene therapy biotech firm that was founded in 2017.

It was set up in a collaborative effort with The Silverstein Foundation for Parkinson’s with GBA (Click here to read a previous SoPD post about this organisation) and OrbiMed (a healthcare-dedicated investment firm).
What does Prevail Therapeutics do?
Recently researchers have provided very interesting evidence that a form of vitamin B3, called Nicotinamide Riboside, may have beneficial effects for Parkinson’s.
Their data suggests that nicotinamide riboside was able to rescue problems in mitochondria – the power stations of cells – in both fly and human cell-based models of Parkinson’s.
And the results also suggest that this treatment could prevent the neurodegeneration of dopamine producing neurons.
In today’s post, we will discuss what nicotinamide riboside is, what is does in the body, how it may be having its beneficial effect, and we will consider the pros and cons of taking it as a supplement.

We have a serious problem in biomedical research at the moment.
Serious for ‘planet research’ that is (Good for ‘planet patient’! – click here to understand this sentence).
The problem is very simple: there is too much research going on, and there is now too much information to be absorbed.
There has been an incredible increase in the number of research reports for ‘Parkinson’s’:
For Parkinson’s research alone, every day there is about 20 new research reports (approximately 120 per week). It used to be the case that there was one big research report per year. Then progress got to the crazy point of one big finding per month. And now things are ‘completely kray kray’ (as my 5 year old likes to say), with one new major finding every week!
On top of this, everyday there are new methodology reports, new breakthroughs in other fields that could relate to what is happening in PD, new clinical trial results, etc… The image below perfectly represents how many researchers are currently feeling with regards to the information flow:

Don’t get me wrong.
These are very exciting times, big steps are being made in our understanding of conditions like Parkinson’s. It’s just that it is really hard keeping up with the amazing flow of new data.
And this is certainly apparent here on the SoPD website. Occasionally, a few days after I publish something on a particular topic on the SoPD website, a fascinating new research report on that same topic will be published. When I get a chance to read it, I will sometimes add an addendum to the bottom of a post highlighting the new research.
Every now and then, however, the new research deserves a post all of its own.
Which is the case today.
A week after I published the recent Vitamin B3/Niacin post, a new study was published that dealt with a different form of Vitamin B3, called Nicotinamide Riboside. And the results of that study were really interesting.
Wait a minute. Vitamin B3 comes in different forms?
New research published in the last week provides further experimental support for numerous clinical trials currently being conducted, including one by the biotech company Sanofi Genzyme.
Researchers have demonstrated that tiny proteins which usually reside on the outer wall of cells could be playing an important role in the protein clustering (or aggregation) that characterises Parkinson’s.
In today’s post we will look at this new research and discuss what it could mean for the on going clinical trials for Parkinson’s.
The proverb ‘When the cat is away, the mice will play’ has Latin origins.
Dum felis dormit, mus gaudet et exsi litantro (or ‘When the cat falls asleep, the mouse rejoices and leaps from the hole’)
It was also used in the early fourteenth century by the French: Ou chat na rat regne (‘Where there is no cat, the rat is king’).
And then Will Shakespeare used it in Henry the Fifth(1599), Act I, Scene II:
Westmoreland, speaking with King Henry V, Gloucester, Bedford, Exeter and Warwick
“But there’s a saying very old and true,
‘If that you will France win,
Then with Scotland first begin:’
For once the eagle England being in prey,
To her unguarded nest the weasel Scot
Comes sneaking and so sucks her princely eggs,
Playing the mouse in absence of the cat,
To tear and havoc more than she can eat”
Interesting. But what does any of this have to do with Parkinson’s?
In addition to looking at current Parkinson’s disease research on this website, I like to look at where technological advances are taking us with regards to future therapies.
In July of this year, I wrote about a new class of engineered viruses that could potentially allow us to treat conditions like Parkinson’s disease using a non-invasive, gene therapy approach (Click here to read that post). At the time I considered this technology way off at some point in the distant future. Blue sky research. “Let’s wait and see” – sort of thing.
So imagine my surprise when an Italian research group last weekend published a new research report in which they used this futurist technology to correct a mouse model of Parkinson’s disease. Suddenly the distant future is feeling not so ‘distant’.
In today’s post we will review and discuss the results, and look at what happens next.

I have said several times in the past that the pace of Parkinson’s disease research at the moment is overwhelming.
So much is happening so quickly that it is quite simply difficult to keep up. Not just here on the blog, but also with regards to the ever increasing number of research articles in the “need to read” pile on my desk. It’s mad. It’s crazy. Just as I manage to digest something new from one area of research, two or three other publications pop up in different areas.
But it is the shear speed with which things are moving now in the field of Parkinson’s research that is really mind boggling!
Take for example the case of Squalamine.
In February of this year, researchers published an article outlining how a drug derived from the spiny dogfish could completely suppress the toxic effect of the Parkinson’s associated protein Alpha Synuclein (Click here to read that post).

And then in May (JUST 3 MONTHS LATER!!!), a biotech company called Enterin Inc. announced that they had just enrolled their first patient in the RASMET study: a Phase 1/2a randomised, controlled, multi-center clinical study evaluating a synthetic version of squalamine (called MSI-1436) in people with Parkinson’s disease. The study will enrol 50 patients over a 9-to-12-month period (Click here for the press release).
Wow! That is fast.
Yeah, I thought so too, but then this last weekend a group in Italy published new research that completely changed my ideas on the meaning of the word ‘fast’. Regular readers will recall that in July I discussed amazing new technology that may one day allow us to inject a virus into a person’s arm and then that virus will make it’s way up to the brain and only infect the cells that we want to have a treatment delivered to. This represents non-invasive (as no surgery is required), gene therapy (correcting a medical condition with the delivery of DNA rather than medication). This new study used the same virus we discussed in July.
