Moving forward into 2019 and beyond, we are going to be getting more sophisticated and targetted with our clinical trials for Parkinson’s. We are gradually moving away from the days when a drug was tested on anyone in the Parkinson’s-affected community, and heading for an age of sub-type specific treatments (Click here for a previous SoPD post on subtyping efforts for PD).
As part of this shift, there are a series of ongoing studies that are trying to identify not only the clinical & biological characteristics of those Parkinson’s sub-types, but also individuals who may already be in those groupings.
One such study is called “Rapsodi” – and it is focused on the identification of people with a particular genetic risk factor of PD – the GBA gene – who also demonstrate the early signs of Parkinson’s.
In today’s post, we will discuss what GBA is, how it is associated with Parkinson’s, and why the Rapsodi study is worthy of the PD community’s attention.

The clinical trial of Ambroxol in Parkinson’s that has been conducted in London (UK) is close to announcing their final results. The Ambroxol study report should be published in early 2019.
What is the ambroxol study?
Started in February 2017, the Ambroxol study (named AiM-PD – Ambroxol in Disease Modification in Parkinson Disease) is a phase IIA prospective, single-centre, open label clinical trial to evaluate the safety, tolerability and pharmacodynamic effects of Ambroxol in Parkinson’s (Click here to read more about this trial and click here for the press release announcing the start of the study).
This trial, which is funded by the Cure Parkinson’s Trust and the Van Andel Research Institute (USA), has been conducted at the Royal Free Hospital in London (UK). The study has involved 20 people with Parkinson’s self-administering Ambroxol (in 60 mg per tablet) over a 6 month time frame. The participants were given 5 escalating doses of the drug for the first few weeks of the study (from 60 mg three times per day, gradually building up to 420 mg three times a day after the first month of the study).
But hang on a second. What is exactly is Ambroxol?
Gaucher disease is a genetic disorder caused by the reduced activity of an enzyme, glucocerebrosidase. This enzyme is produced by a region of DNA (or a gene) called GBA – the same GBA gene associated with a particular form of Parkinson’s.
Recently, a Danish company has been testing a new drug that could benefit people with Gaucher disease.
It is only natural to ask the question: Could this drug also benefit GBA-associated Parkinson’s?
In today’s post, we will discuss what Gaucher disease is, how this experimental drug works, and why it would be interesting to test it in Parkinson’s.

The title of this post is a play on words from one of the many famous lines of William Shakespeare’s play, Hamlet.
The original line – delivered by Marcellus (a Danish army sentinel) after the ghost of the dead king appears – reads: If the authorities knew about the problems and chose not to prevent them, then clearly something is rotten in the state of Denmark.
(Act 1, Scene 4)
The title of this post, however, is: Something is interesting in the state of Denmark
This slight change was made because certain Danish authorities know about the problem and they are trying to prevent it. The ‘authorities’ in this situation are some research scientists at a biotech company in Denmark, called Orphazyme.
And the problem is Parkinson’s?
No, the problem is Gaucher disease.
Huh? What is Gaucher disease?
