Very tough week for the Parkinson's community with back-to-back failures of Roche's prasinezumab and UCB's minzasolmin, both targeting alpha-synuclein proteins: https://lnkd.in/dHfwzyjg A lot of data remains to be unpacked, but prasinezumab now qualifies as one of the most heavily studied Parkinson's drugs ever. Over the past 11 years, it has been tested in >900 patients, including some who have been on it for >4 years in an open-label extension. In 2025, we’ll join the rest of the Parkinson's community in reflecting on what these results teach us about alpha-synuclein’s role in Parkinson’s disease—and, more broadly, how to improve the process of drug development for Parkinson’s going forward. One big missing piece is the lived experience of patients who participated, especially those in the 4+ year open-label extension. I hope their stories emerge in the coming months. 🧠
And why we still require those afflicted exhaust all these useless "treatments" rather than go straight to deep brain stimulation is killer stupid.
Nailed it! Patient experience must absolutely be considered. PD is insanely variable among each person. I've yet to understand how a PD study can be objective when it is measuring outcomes with so much variability as well as a relatively unknown pathology🤷🏻♀️
The dopamine neurons aren't going to grow back, no matter how much alpha synuclein is removed. Removing A-beta doesn't reverse Alzheimer's disease, either. We need more thinking about cell replacement and regenerative approaches.
We need to confront reality and move beyond the established norms that have long defined neuro drug discovery. Our approach to collecting biological data on neuro patients mirrors how Big Tech gathers information on users, yet our drug development efforts have largely focused on a few genetic targets identified in familial cases, hoping they will translate to sporadic forms. To drive meaningful change, we must be bold and change the way we approach this problem.

3moWell said Brian, well said. We must enable the community to learn from trials such as these at a much faster rate. Our lives depend on it.
