This week the outcome of an ongoing Parkinson’s clinical trial was announced.
Data collected during Part 1 of the ongoing Phase 2 PASADENA alpha synuclein immunotherapy study for Parkinson’s apparently suggests that the treatment – called prasinezumab – has not achieved it’s primary endpoint (the pre-determined measure of whether the agent has an effect in slowing Parkinson’s progression – in this case the UPDRS clinical rating scale).
But, intriguingly, the announcement did suggest ‘signals of efficacy‘ in secondary and exploratory measures.
In today’s post, we will discuss what immunotherapy is, what we know about the PASADENA study, and why no one should be over reacting to this announcement.

At 7am on Wednesday, April 22nd, 2020, the pharmaceutical company Roche published its sales results for the 1st Quarter. This was just prior to the opening of the Swiss Stock Exchange. The financial report looked very good, particularly considering the current COVID-19 economic climate.
There was, however, one sentence on page 133 of the results that grabbed some attention:
For those of you (like myself) who struggle with fine print, the sentence reads:
“Study did not meet its primary objective, but showed signals of efficacy“
This was how the pharmaceutical giant announced the top line result of the ongoing Phase II PASADENA study evaluating the immunotherapy treatment prasinezumab in recently diagnosed individuals with Parkinson’s (listed on the Clinicaltrials.gov as NCT03100149).
At the time of publishing this SoPD post, Roche are yet to provide any further information (press release, announcement, memo, tweet, etc) regarding the results of the study.
Thankfully, a smaller biotech firm called Prothena – which is also involved in the development of the agent being tested in the Pasadena study – has kindly provided a few more details regarding these results.
In today’s post we will discuss what details have been shared in the Prothena press release regarding the Prasinezumab clinical trial in Parkinson’s (Click here to read the press release).
What is Prasinezumab?
This week Austrian biotech firm, AFFiRiS AG, made an announcement regarding their experimental immunotherapy/’vaccine’ approach for Parkinson’s.
In their press release, the company provided the results of a long-term Phase I clinical trial testing the tolerability and safety of their treatment AFFITOPE® PD01A.
The treatment was found to be safe and well-tolerated in people with Parkinson’s. But there was one sentence which was particularly intriguing in the press release regarding clinical symptoms.
In today’s post, we will discuss what is meant by ‘immunotherapy’, outline what this particular clinical trial involved, review the results, and explore what this could mean for the Parkinson’s community.
I have previously mentioned on this website that any ‘cure for Parkinson’s’ is going to require three components:
- A disease halting mechanism
- A neuroprotective agent
- Some form of cell replacement therapy
This week we got some interesting clinical news regarding the one of these components: A disease halting mechanism
Clinical trial results from Austria suggest that a new immunotherapy approach in people with Parkinson’s is both safe and well tolerated over long periods of time.

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.
