The 2019 ADPD meeting

 

On the 26-31st March, the 14th International Conference on Alzheimer’s and Parkinson’s Diseases (or ADPD meeting) was held in Lisbon, Portugal.

For 5 days – between 8:30am and 7:30pm each day – over 4000 researchers were able to attend lectures of new results and ideas, in any of 8 different auditoriums. Alternatively, they could wander among hundreds of research posters.

It was a marathon effort, however, for all attendees. And a great deal of new results were shared.

In today’s post, we will discussed what was presented at the 2019 ADPD meeting and what was actually learnt.

Lisbon is a city, midway down the western coast of the Iberian Peninsula.

It is home to a little over 500,000 people (3 million in the wider metropolitan area), and it serves as the capital city for the Portuguese people.

Interestingly, it is the 2nd oldest European capital city (after Athens), and has had a rich and fascinating history given its strategic location. But on the 1st November 1755, 20% of the population were killed and 85% of the city’s structures were destroyed by a terrible earthquake and subsequent tsunami, which resulted in the vast majority of the city being rebuilt.

The ‘new city’ is laid out in bairros de Lisboa (neighbourhoods of Lisbon) across a hilly landscape, providing views of the River Tagus at every vantage point. And while walking the steep cobblestoned streets is delightful, there is a system of vintage public trams that can take a lot of the leg work out of the effort.

During the last week of March 2019, Lisbon was the site of the ADPD meeting.

The Bristol GDNF results

 

Today – 27th February, 2019 – the long-awaited results of the Phase II GDNF clinical trial were published.

GDNF (or glial cell line-derived neurotrophic factor) is a protein that our bodies naturally produce to nurture and support cells. Extensive preclinical research suggested that this protein was particularly supportive of dopamine neurons – a group of cells in the brain that are affected by Parkinson’s.

The results of the Phase II clinical trial suggest that the treatment was having an effect in the brain (based on imaging data), but the clinic-based methods of assessment indicated no significant effect between the treatment and placebo groups.

In today’s post we will look at what GDNF is, review the previous research on the protein, discuss the results of the latest study, and look at what happens next.

And be warned this is going to be a long post!

It all began way back in 1991.

George H. W. Bush was half way into his presidency, a rock band called Nirvana released their second album (‘Nevermind’), Michael Jordan and the Chicago Bulls rolled over the LA Lakers to win the NBA championship, and Arnold Schwarzenegger’s ‘Terminator 2’ was the top grossing movie of the year.

But in the city of Boulder (Colorado), a discovery was being made that would change Parkinson’s research forever.

In 1991, Dr Leu-Fen Lin and Dr Frank Collins – both research scientists at a small biotech company called Synergen, isolated a protein that they called glial cell-derived neurotrophic factor, or GDNF.

And in 1993, they shared their discovery with the world in this publication:

Title: GDNF: a glial cell line-derived neurotrophic factor for midbrain dopaminergic neurons.
Authors: Lin LF, Doherty DH, Lile JD, Bektesh S, Collins F.
Journal: Science, 1993 May 21;260(5111):1130-2.
PMID: 8493557

For the uninitiated among you, when future historians write the full history of Parkinson’s, there will be no greater saga than GDNF.

In fact, in the full history of medicine, there are few experimental treatments that people get more excited, divided, impassioned and evangelical than GDNF.

This ‘wonder drug’ has been on a rollercoaster ride of a journey.

What exactly is GDNF?

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.

2017 – Year in Review: A good vintage

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

The EMPRSN talk #1

Recently I was invited to speak at the 6th Annual East Midlands Parkinson’s Research Support Network meeting at the Link Hotel, in Loughborough. The group is organised and run by the local Parkinson’s community and supported by Parkinson’s UK. It was a fantastic event and I was very grateful to the organisers for the invitation.

They kindly gave me two sessions (20 minutes each) which I divided into two talks: “Where we are now with Parkinson’s research?” and “Where we are going with Parkinson’s research?”. Since giving the talk, I have been asked by several attendees if I could make the slides available.

The slides from the first talk can be found by clicking here.

I have also made a video of the first talk with a commentary that I added afterwards. But be warned: my delivery of this second version of the talk is a bit dry. Apologies. It has none of my usual dynamic charm or energetic charisma. Who knew that talking into a dictaphone could leave one sounding so flat.

Anyways, here is the talk – enjoy!

I hope you find it interesting. When I have time I’ll post the second talk.
