(2) Robust preclinical data support the benefit of PRX005, a novel anti-tau antibody, for the potential treatment Alzheimer's disease New pre-specified exploratory subgroup analyses and new digital biomarker data from Part 1 of the Phase 2 PASADENA study of prasinezumab in patients with early Parkinson's disease will be featured in two separate presentations DUBLIN, Ireland, Feb. 24, 2021 (GLOBE NEWSWIRE) -- Prothena Corporation plc (NASDAQ:PRTA), a late-stage clinical company with expertise in protein dysregulation and a pipeline of investigational therapeutics for rare peripheral amyloid and neurodegenerative diseases, today announced three oral presentations and participation in a live forum at The 15 th International Conference on Alzheimer's and Parkinson's Diseases (AD/PD 2021). Prothena will present new preclinical data demonstrating that targeting a novel epitope with PRX005, an anti-tau antibody, resulted in superior attributes for the potential treatment of Alzheimer's disease. PRX005 is being developed as part of the Company's global neuroscience collaboration with Bristol Myers Squibb. In addition, Roche will present new pre-specified exploratory subgroup analyses from Part 1 of the Phase 2 PASADENA study of prasinezumab in patients with early Parkinson's disease and, separately, new digital biomarker data from its remote monitoring technology used in the study.
