The road ahead: 2020

Here at the SoPD, we are primarily interested in disease modification for Parkinson’s. While there is a great deal of interesting research exploring the causes of the condition, novel symptomatic therapies, and other aspects of Parkinson’s, my focus is generally on the science seeking to slow, stop or reverse the condition.

At the start of each year, it is a useful practise to layout what is planned and what we will be looking for over the next 12 months. Obviously, where 2020 will actually end is unpredictable, but an outline of what is scheduled over the next year will hopefully provide us with a useful resource for better managing expectations.

In this post, I will try to lay out some of what 2020 holds for us with regards to clinical research focused on disease modification for Parkinson’s.

My old scout master once looked around our horse shoe, making eye contact with each of us, before asking the question:

“When did Noah build the ark?”

My fellow scouts and I looked at each other – confused. Did he want an exact date?!?

The scout master waited a moment for one of us to offer up some idiotic attempt at an answer – thankfully no one did – before he solemnly said:

“Before the rain”

It was one of those childhood moments that made little sense at the time, but comes back to haunt you as an adult when you are looking at what the future may hold and trying to plan for it.

Today’s post is our annual horizon scanning effort, where we lay out what is on the cards for the next 12 months with regards to clinical research focused on disease modification in Parkinson’s.

We will also briefly mention other bits and pieces of preclinical work that we are keeping an eye on for any news of development.

To be clear, this post is NOT intended to be an exercise in the reading of tea leaves – no predictions will be made here. Nor is this a definitive or exhaustive guide of what the next year holds for disease modification research (if you see anything important that I have missed – please contact me). And it should certainly not be assumed that any of the treatments mentioned below are going to be silver bullets or magical elixirs that are going to “cure” the condition.

In the introduction to last year’s outlook, I wrote of the dangers of having expectations (Click here to read that post). I am not going to repeat that intro here, but that the same message applies as we look ahead to what 2020 holds.

In fact, it probably applies even more for 2020, than it did for 2019.

2020 is going to be a busy year for Parkinson’s research, and I am genuinely concerned that posts like this are only going to raise expectations. My hope is that a better understanding of where things currently are and what is scheduled for the next 12 months will help in better managing those expectations. Please understand that there is still a long way to go for all of these experimental therapies.

All of that said, let’s begin:

The 2019 Linked Clinical Trials meeting

 

Things were a bit quiet on the SoPD over the summer, but for good reasons. There was a short hiatus for a family break, but the rest of the time I was rather occupied with the day job. Tremendous efforts were being made at the Cure Parkinson’s Trust, as we were gearing up for our main event of the year: the Linked Clinical Trials (LCT) meeting.

This is an annual meeting at which 20 Parkinson’s experts from around the world, gather for a two day face-to-face pow-wow. They evaluate dossiers which contain everything we know about 20+ compounds which have exhibited potential for disease modification in Parkinson’s. The goal of the committee is to decide which of them is ready for clinical evaluation.

The writing of those LCT dossiers is a year long exercise, which inevitably becomes a bit of a panic in June and July (hence the lack of activity here at SoPD HQ during that period). It is a mammoth, marathon task, but as you shall see it is one that I rather like.

In today’s post, we will discuss what the Linked Clinical Trials initiative is, the process behind the project, and some of the progress being made by the programme.

Archimedes of Syracuse (287 BC – 212 BC) the ancient Greek mathematician, once said that the “shortest distance between two points is a straight line“.

My dad (who is not a regular readers of this blog, but is possibly on par with Archie – just in case he does ever read this) has often been heard saying “Just get to the point Simon“.

Millennia apart, but their collective wisdom is same: Ignore everything else, and get straight to the heart of the matter as quickly as you can.

And this is one of the aspect I really like about the Linked Clinical Trials initiative.

It is all about getting to potentially disease modifying treatments for Parkinson’s to the community as quickly as possible.

What is the Linked Clinical Trials programme?

The road ahead: Parkinson’s research in 2018

The great ice hockey player Wayne Gretzky once said “A good hockey player plays where the puck is. A great hockey player plays where the puck is going to be” (the original quote actually came from his father, Walter). 

At the start of each year, it is a useful practise to layout what is planned for the next 12 months. This can help us better anticipate where ‘the puck’ will be, and allow us to prepare for things further ahead.

2017 was an incredible year for Parkinson’s research, and there is a lot already in place to suggest that 2018 is going to be just as good (if not better).

In this post, we will lay out what we can expect over the next 12 months with regards to the Parkinson’s-related clinical trials research of new therapies.

Many readers will be familiar with the name Warren Buffett.

The charming, folksy “Oracle of Omaha” is one of the wealthiest men in the world. And he is well known for his witticisms about investing, business and life in general.

He regularly provides great one liners like:

“We look for three things [in good business leaders]: intelligence, energy, and integrity. If they don’t have the latter, then you should hope they don’t have the first two either. If someone doesn’t have integrity, then you want them to be dumb and lazy”

“Work for an organisation of people you admire, because it will turn you on. I always worry about people who say, ‘I’m going to do this for ten years; and if I really don’t like it very much, then I’ll do something else….’ That’s a little like saving up sex for your old age. Not a very good idea”

“Choosing your heroes is very important. Associate well, marry up and hope you find someone who doesn’t mind marrying down. It was a huge help to me”

Mr Buffett is wise and a very likeable chap.

Few people, however, are familiar with his business partner, Charlie Munger. And Charlie is my favourite of the pair.

Glutathione – Getting the k’NAC’k of Parkinson’s disease

NAC

The image above presents a ‘before treatment’ (left) and ‘after treatment’ (right) brain scan image from a recent research report of a clinical study that looked at the use of Acetylcysteine (also known as N-acetylcysteine or simply NAC) in Parkinson’s disease.

DaTscan brain imaging technique allows us to look at the level of dopamine processing in an individual’s brain. Red areas representing a lot; blue areas – not so much. The image above represents a rather remarkable result and it certainly grabbed our attention here at the SoPD HQ (I have never seen anything like it!).

In today’s post, we will review the science behind this NAC and discuss what is happening with ongoing clinical trials.

Let me ask you a personal question:

Have you ever overdosed on Paracetamol?

Regardless of your answer to that question, one of the main treatments for Paracetamol overdose is administration of a drug called ‘Acetylcysteine’.

Why are you telling me this?

Because acetylcysteine is currently being assessed as a potential treatment for Parkinson’s disease.

Oh I see. Tell me more. What is acetylcysteine?

Acetylcysteine (N-acetylcysteine or NAC – commercially named Mucomyst) is a prodrug – that is a compound that undergoes a transformation when ingested by the body and then begins exhibiting pharmacological effects. Acetylcysteine serves as a prodrug to a protein called L-cysteine, and – just as L-dopa is an intermediate in the production of dopamine – L-cysteine is an intermediate in the production of another protein called glutathione.

Take home message: Acetylcysteine allows for increased production of Glutathione.

What is glutathione?

Glutathione (pronounced “gloota-thigh-own”) is a tripeptide (a string of three amino acids connected by peptide bonds) containing the amino acids glycine, glutamic acid, and cysteine. It is produced naturally in nearly all cells. In the brain, glutathione is concentrated in the helper cells (called astrocytes) and also in the branches of neurons, but not in the actual cell body of the neuron.

It functions as a potent antioxidant.
