The “What would I do” post? Part 2

# # # #

I am very regularly asked “what would you do if you were diagnosed with Parkinson’s tomorrow?”

As a research scientist I don’t really feel comfortable answering it, but I can see how it is a fair question. I have previously attempted to address it (Click here to read that post), and I point folks who do ask in the direction of that post.

But a recent experience has me wanting to re-address it.

In today’s post, we will revisit this idea of what would I do if I were diagnosed with Parkinson’s tomorrow?

I lost someone extremely close to me early last year.

Even more than COVID19 or anything else that occurred, that singular event defined 2021 for me personally. There was life before, and now life adjusting to being without them.

And I’m not sharing this out of any desire for sympathy – honestly, I don’t want it. Everyone has suffered hardships over the last 2 years. Rather, I am telling you this for a very different reason.

It helps to set the context for the discussion today.

The road ahead: 2022

# # # #

The first post at the start of each year on the SoPD website tries to provide an overview of where things are in the search for ‘disease modifying’ therapies for Parkinson’s. 

It is an exercise in managing expectations as well as discussing what research events are scheduled for the next year so that we can keep an eye out for them. I will also note aspects of ongoing research where I will be hoping to see an update on progress. Obviously, where 2022 will actually end is unpredictable, but an outline of what is coming over the next 12 months will hopefully provide the community with a useful resource.

While there is a great deal of interesting research exploring the causes of the condition, the genetics and biology of the condition, novel symptomatic therapies, and other aspects of Parkinson’s, the primary focus in this post is on the clinical trial research seeking to slow, stop or reverse the condition.

In this post, we will hopefully give readers a taste of what the landscape looks like for clinical research focused on disease modification for Parkinson’s.

If you have men who will only come if they know there is a good road, I don’t want them. I want men who will come if there is no road at all.

David Livingstone

The Scottish physician Dr David Livingstone – missionary and explorer – led an interesting life.

Most of us only know of him for his fabled adventures in Africa. But they are made more remarkable given his extremely humble beginnings.

Born into poverty, Livingstone started his working life at 10 years of age in a cotton factory, where he worked from 6am till 8pm everyday. He somehow managed to get some schooling around those work shifts, and his impoverished family saved enough money so that he could attend Anderson’s University (Glasgow) when he was 23.

Cotton factory (Source)

How he got from the cotton factory to becoming the first European to cross the width of southern Africa (as well as ‘discovering’ the Mosi-oa-Tunya waterfalls – aka Victoria Falls), was one of the great rag-to-riches stories of Victorian times and making him something of a celebrity of the age.

But his mapping out of central Africa was his greatest legacy.

As a biographer wrote “Through him, the centre of Africa ceased to be a dark, unknown space on the map and became a real place, full of interesting human beings [and] wonderful wildlife. . . .” (Source)

It has to be acknowledged, however, that Livingstone was not able to explore the entirety of the Zambezi River system himself so he would often ask the local people for information, and he would then incorporate their contributions into his maps.

Livingstone’s travels (Source)

“We travel in the company of men who are well acquainted with parts of the country by personal observation… They soon see that we are interested in the courses of rivers, names of hills, tribes…and make enquiries among the villagers to whom we come. Drawings are made on the ground and parts pointed out that bearings may be taken and comparisons drawn from the views of different individuals. We thus gain a general idea of the whole country” (Source)

It makes one appreciate that maps are collaborative efforts, incorporating the efforts of lots of different parties. And it is only by going through the process of mapping something out that we start to understand it, know our place in it, observe the limitations to our knowledge, and perhaps find something of what we are looking for.

At the start of each year, the SoPD publishes a horizon scanning post where we take a Livingstone-like approach towards mapping out the landscape of clinical research focused on disease modification for Parkinson’s, and what follows is the 2022 version.

Year in review: 2021

# # # #

As with the preceding year, 2021 proved to be challenging due to the continuing COVID-19 pandemic (and it is not over yet). Vaccines were rolled out with remarkable speed, but equally new variants of the virus popped up and have kept Governments and health regulatory bodies on their toes.

An amazing feature of the last two years has been the response to the pandemic from the research community – not only in sequencing novel variants and testing new vaccines – but also in terms of keeping research projects ongoing in other fields of science. Despite everything pandemic-related, there has been significant progress in areas like Parkinson’s research.

In today’s post, we will consider three big Parkinson’s-related research takeaways of 2021 (based on our humble opinions here at the SoPD), and then we will provide an extended overview of some of the important discoveries and pieces of news from the last 12 months (Be warned: this will be a long post).

There are 52.143 weeks in a year, which equates to:

  • 365 sun rises and sunsets
  • Approximately 13.3 lunar orbits (Source)
  • 8 760 hours
  • US$93.86 trillion in global gross domestic production (nominal terms; 194 economies in 2021 – Source)
  • 525 600 minutes
  • 29.2 tons of adenosine triphosphate (ATP) production and recycling (per person – based on an average 80kg individual)
  • 31 622 400 seconds (Source)
  • Approximately 35 million heart beats and  8.4 million breaths

Basically, ample time and resources to do some useful stuff (beyond simply binging “Squid games” on Netflix or playing “candy crunch”).

The last 52.143 weeks have been particularly challenging in many countries due to the ongoing COVID-19 situation. Despite these ongoing challenges, significant progress has been made in the research surrounding Parkinson’s and other neurodegenerative conditions in 2021.

Below we will discuss three of the main research-related pieces of news for Parkinson’s (as determined by the team here at SoPD HQ), before providing a month-by-month overview of the note worthy events.

The terazosin pilot study results

# # # #

Drug repurposing represents a means of rapidly testing and bring novel therapies to the patient. By testing clinically available drugs – that have well characterised safety records in a particular medical condition – one can determine if a certain biological pathway is playing an influential role in another disease.

A good example of this is work currently being done by researchers at the University of Iowa with a drug called terazosin. Terazosin is a treatment used for enlarged prostate issues and high blood pressure, but recent epidemiological data and preclinical work indicates that it may also be useful for Parkinson’s.

Recently the team in Iowa published a report on a small pilot clinical study evaluating the agent in a group of people with Parkinson’s.

In today’s post, we will look at what terazosin does, discuss what the preclinical and epidemiological research suggests, review the results of the pilot study, and discuss what could happen next.

There has been a lot of important Parkinson’s research conducted in the state of Iowa.

For example, in addition to producing a quarter of the USA’s corn and 1/3 of America’s pork, Iowa is also the home to a large family known to researchers as the ‘Iowa kindred‘ or ‘Spellman-Muenter kindred‘.

First described by Spellman in 1962, the Iowa kindred has a long history in which generations of the family have been inflicted with severe parkinsonisms (the symptoms/features of PD). In the family tree below, the black diamonds represent individuals with Parkinsonisms:

In 2003, researchers discovered that this family was carrying a multiplication of their alpha synuclein gene:

Title: alpha-Synuclein locus triplication causes Parkinson’s disease.
Authors: Singleton AB, Farrer M, Johnson J, Singleton A, Hague S, Kachergus J, Hulihan M, Peuralinna T, Dutra A, Nussbaum R, Lincoln S, Crawley A, Hanson M, Maraganore D, Adler C, Cookson MR, Muenter M, Baptista M, Miller D, Blancato J, Hardy J, Gwinn-Hardy K.
Journal: Science. 2003 Oct 31;302(5646):841.
PMID: 14593171

The publication of this report was an important moment in Parkinson’s research history (Click here to read a SoPD post about the early history of alpha synuclein).

More recently, some researchers at the University of Iowa are hoping to continue this legacy of important Parkinson’s research by investigating the potential of a clinically available drug to slow the progression of Parkinson’s.

Slow-wave sleep saves synucleinopathy?

 

# # # #

Good sleep patterns have important implications for all of us in terms of health and well being, but sleep is often disrupted for people with Parkinson’s.

Research suggests that people with Parkinson’s have reduced amounts of slow wave and REM sleep, and increased periods of wakefulness.

A new report has found that increasing levels of slow wave sleep could have beneficial effects in reducing the accumulation of alpha synuclein protein in the brain.

In today’s post, we will discuss what sleep is, how it is affected in Parkinson’s, and what the new research indicates about slow wave sleep.

I am a night owl.

One that is extremely reluctant to give up each day to [the waste of precious time that is] sleep. There is always something else that can be done before going to bed. And I can often be found pottering around at 1 or 2am on a week night.

Heck, most of the SoPD posts are written in the wee small hours (hence all of the typos).


Source: Iristech

As a result of this foolish attitude, I am probably one of the many who live in a state of sleep deprivation – I am a little bit nervous about doing the spoon test:

And the true stupidity of my reluctance to adopt a healthy sleep pattern is that I fully understand that sleep is extremely important for our general level of health and well being.

In addition, I am also well aware of an accumulating pool of research that suggests sleep could be influential in the initiation and progression of neurodegenerative conditions, like Parkinson’s.

Wait, how is sleep associated with Parkinson’s?

From wearables to invisibles

# # # #

New technologies that can help us to better understand and track Parkinson’s over time has been a theme here on the SoPD. Such tools could create fantastic opportunities, particularly in the context of clinical trials evaluating new therapies, by providing comparable quantitative measures.

Many of these efforts have focused on wearable technologies that require user input – mostly in the form of actually remembering to put the device on or to manually input data on a regular basis.

More recently, however, some researchers have been investigating ‘invisibles’ rather than ‘wearables’, and the results have been rather remarkable.

In today’s post, we will discuss how WI-FI technology is helping to better assess and measure Parkinson’s, and other medical conditions.

During the COVID19 pandemic, working from home has largely depended on availability of this strange thing called WI-FI. And as a result this strange thing called WI-FI has become a critical aspect of our daily lives.

The necessity of this strange thing called WI-FI becomes apparent when Zoom or Teams sessions are interrupted by a weak signal from this strange thing called WI-FI.

Source: Highspeedinternet

But what exactly is this strange thing called WI-FI?

It is often said to be short for “Wireless Fidelity“, but it is not.

The generic term “WI-FI” was actually created by the marketing firm Interbrand (Source) because the wireless industry was looking for a more user-friendly name to refer to the not so user-friendly technology known as “IEEE 802.11b Direct Sequence” (Source).

WLAN (or Wireless Local Area Network) was an option, but it didn’t really have a catchy ring to it. In the end, WI-FI – a pun upon the word HI-FI – was selected and the rest is history.

WI-FI refers to the communication standard for the wireless network that has been around since the 1990s. It works as a Local Area Network for electronic devices to operate without using any types of cable or wiring.

Most people use it for important tasks, like binge streaming ‘Squid Games’. But recently researchers have found other uses for this strange thing called WI-FI.

ADepTing to the UCB-Novartis deal

# # # #

Alpha synuclein has long been viewed at “Public enemy #1” by the Parkinson’s research community. This sticky, abundant protein starts to cluster (or aggregate) in Parkinson’s.

There have been several attempts to reduce levels of the protein floating around outside of cells (using “immunotherapy” approaches)

But now clinical research is ramping up to determine if reducing aggregated alpha synuclein levels in the brain could help to slow/stop the progression of the condition.

In today’s post, we will look at three different lines of clinical research focused on small molecule inhibitors of alpha synuclein aggregation. 

# # # #


When someone mentions the pharmaceutical firm Novartis, it feels like the company has been around forever, but it is actually not that old.

It was created in March 1996 via the merger of two Swiss companies: Ciba-Geigy and Sandoz. The roots of those companies can be traced back more than 250 years, but the combined entity is still a spring chicken compared to many of its major competitors.

The name Novartis results from the combination of two words “Nova Artes”, which means new art and innovation in simple forms, but there is little in what the company does that is ‘simple’. A good example of this was their block buster cancer drug Gleevec/Glivec (imatinib) which was developed by careful “rational drug design” for very specific types of cancer.

The reputation for Swiss precision seems to flow through this company and they are always making very carefully placed bets.

Which makes their news this week rather interesting.

What news did they have?

Getting a handle on Miro1

# # # #

Novel therapeutic interventions are being proposed for Parkinson’s on a regular basis, with compelling data supporting their future development.

The case is strengthened when a measure of target engagement is also involved – providing not only a potential therapy but also a biomarker as well.

Recently, a biotech company called AcureX Therapeutics has been presenting just such a case, based on a biological mechanism involving the protein Miro1.

In today’s post, we will discuss what Miro1 is and how it might be useful for future clinical trials.

# # # #


 

Watching the recent Michael J Fox Foundation‘s Progress in the PD Pipeline webinar (Wednesday 10th November, 2021), I was really impressed by the presentation by Dr Bill Shrader (co-founder and CEO/CSO of AcureX Therapeutics)

 

In particular, I really liked their approach to potential patient selection for future clinical trials of their lead drug candidate. It all revolves around the analysis of Miro1 as a biomarker.

What is Miro1?

Monthly research review – November 2021

# # # #

At the end of each month the SoPD writes a post which provides an overview of some of the major pieces of Parkinson’s-related research that were made available during November 2021.

The post is divided into 10 parts based on the type of research:

# # # #


So, what happened during November 2021?

In world news:

November 1 – American psychiatrist Professor Aaron Beck –  the father of cognitive therapy and cognitive behavioral therapy (or CBT) – passed away.

 

November 13th – The 2021 United Nations Climate Change Conference came to an ignominious conclusion with more blah-blah promises by world “leaders”, which included a “phasedown” of unabated coal power, a 30% cut in methane emissions by 2030, and plans for a halt to deforestation by 2030. And then they all hopped back on their planes and left. Perhaps in a world of zoom meetings, we can agree to “phasedown” COP conferences instead?

 

November 26 – The World Health Organization convened an emergency meeting in Geneva amid concerns over “Omicron” – a highly mutated variant of COVID-19 in South Africa that appears more infectious than Delta.

 

November 29th – Researchers presented synthetic multicellular assemblies (“xenobots”) that can replicate kinematically by moving and compressing dissociated cells in their environment into functional self-copies (Click here to read the report and click here to read a press release on the topic).

November 29th – The number of research reports on the Pubmed search engine with the keyword “Parkinson’s” climbed over 150,000. Approximately 118,000 (~80%) of them have been published since the year 2000, & 75,494 (~50%) since 2012.

In the world of Parkinson’s research, a great deal of new research and news was reported:

In November 2021, there were 919 research articles added to the Pubmed website with the tag word “Parkinson’s” attached (10,965 for all of 2021 so far). In addition, there was a wave to news reports regarding various other bits of Parkinson’s research activity (clinical trials, etc).

The influence of influenza

# # # #

The potential long-term consequences of viral infections is not a popular topic for a research blog in the middle of a pandemic (and yes, we are still in the middle of it!), but there is a recent Parkinson’s-related report that is worth discussing.

Researchers have recently looked at medical records dating back several decades and noticed something interesting about influenza infections: They are associated with diagnoses of Parkinson’s more than 10 years after infection.

NOTE: The data does not indicate a causal link, just an association.

In today’s post, we will discuss what influenza is, how it has previously been associated with PD, what the new report found, and we will speculate on potential mechanisms by which viral infections could be playing a role in Parkinson’s.

1918 Spanish flu. Source: Chronicle

Between January 1918 and December 1920, there were two outbreaks of an influenza virus during an event that became known as the 1918 flu pandemic.

Approximately 500 million people across the globe were infected by the H1N1 influenza virus, and this resulted in 50 to 100 million deaths (approximately 3-5% of the world’s population). Given that it occurred during World War 1, censors limited the media coverage of the pandemic in many countries in order to maintain morale.

The Spanish media were not censored, however, and this is why the 1918 pandemic is often referred to as the ‘Spanish flu’.

At the same time that H1N1 was causing havoc, a Romanian born neurologist named Constantin von Economo reported a number of cases involving unusual symptoms. The collection of symptoms was eventually given a name: encephalitis lethargica (EL).

This disease left victims in a statue-like condition, speechless and motionless. By 1926, EL had spread around the world, with nearly five million people being affected.
