Parkinson's drug developers are betting big on inflammation
Jefferies says Parkinson’s drug development is shifting toward neuroinflammation, while still pursuing alpha-synuclein. It estimates the addressable early US and EU population could exceed 2 million by 2035, implying a ~$8 billion disease-modifying therapy market. It cites Roche’s prasinezumab missed endpoints twice but moved to Phase III, and Denali’s BIIB122 failed broadly. Companies mentioned include Ventyx (VTYX), BioVie (BIVI), and Tiziana (TLSA).
