It was conducted across a nation-wide network of 23 hospitals, recruiting over 230 participants to take part. The courageous participants were randomly assigned at the start of the trial to take either simvastatin or a placebo treatment for 2 years and undergo regular clinical assessments.
This week the results of that study have been released and they indicate that the treatment has had no impact on slowing the progression of Parkinson’s. Read more here. The results of the study will be presented by Dr Carroll at the virtual 2020 Movement Disorder Society meeting this week, and they will be written up and published in a scientific journal in the near future.
“Given the strength of pre-clinical evidence, and the progress with simvastatin already being made in MS, this is a disappointing result. However, we now have a definitive answer, and that enables us to move forward to test a number of other drugs of interest, many of which have been used to treat other diseases, and all of which we have determined have compelling evidence they each have the potential to modify Parkinson’s progression.”
Dr Richard Wyse, Director of Research & Development at The Cure Parkinson’s Trust
The Cure Parkinson’s Trust would like to thank the participants who contributed not only to the trial but also to the numerous sub-studies that have been part of this wider project. ‘Added value’ sub-studies – that investigate new methods of assessment and biomarkers – are a critical component of all of The Cure Parkinson’s Trust supported trials. They provide additional insights and information that can be broadly applied to future clinical trials even in the event of a disappointing treatment result. The added value data from the PD-STAT study will have important implications on how future clinical studies exploring disease modification in Parkinson’s are designed and conducted.
“There are lots of positives to come out of this study, particularly the extent to which we were able to involve participants across the country, and the very positive feedback received from them and staff in the hospitals involved. PD-STAT has taught us a huge amount about how to improve the way we design and deliver clinical trials in Parkinson’s and this knowledge will be very useful in designing future trials”
