DUBLIN, Ireland, Oct. 20, 2020 (GLOBE NEWSWIRE) -- Prothena Corporation plc (NASDAQ:PRTA), a late-stage clinical company with expertise in protein dysregulation and a diverse pipeline of investigational therapeutics for neurodegenerative and rare peripheral amyloid diseases, today announced that based on positive signals of efficacy consistent with disease modification in the PASADENA study, Roche and Prothena plan to advance prasinezumab into a Phase 2b study in patients with early Parkinson's disease. The study will be designed to further assess the efficacy of prasinezumab by expanding upon the patient population enrolled in PASADENA to include patients with early Parkinson's disease on stable levodopa therapy. Prasinezumab is the first anti-alpha synuclein antibody to advance into late-stage development. Prothena will earn a $60 million clinical milestone payment upon first patient dosed in this study. Further details are expected to be announced in the first half of 2021.

Prothena to Hold Investor Webcast to Discuss Results from Phase 2 PASADENA Study Presented at the International Parkinson and Movement Disorder Society's MDS Virtual Congress

DUBLIN, Ireland, Sept.  11, 2020  (GLOBE NEWSWIRE) -- Prothena Corporation plc (NASDAQ:PRTA), announced that results from the Phase 2 PASADENA study of prasinezumab are being highlighted today at the International Parkinson and Movement Disorder Society's MDS Virtual Congress 2020 (MDS Congress). Prasinezumab is the first potentially disease-modifying, anti-alpha-synuclein antibody to demonstrate signals of efficacy on multiple pre-specified secondary and exploratory clinical endpoints in patients with early Parkinson’s disease. As previously reported, the study did not meet the primary objective, but signals of efficacy showing a reduction in disease progression were observed in both of the prasinezumab arms when compared to placebo. In the study, prasinezumab significantly reduced decline in motor function by 35% (pooled dose levels) vs. placebo after one year of treatment on the centrally rated assessment of Movement Disorder Society-Unified Parkinson's Disease Rating Scale (MDS-UPDRS) Part III, a clinical examination of motor function. Motor symptoms associated with Parkinson’s disease include slowness of movement (bradykinesia), tremor, rigidity, and gait. Prasinezumab-treated patients also demonstrated a significant delay in time to clinically meaningful worsening of motor progression on the site rated assessment of time to at least a 5-point progression on MDS-UPDRS Part III vs. placebo over one year, with a hazard ratio of 0.82 (pooled dose levels). There are currently no treatments available that target the underlying cause of Parkinson’s disease and can slow its progression.
