Researchers from Massachusetts General Hospital recently detailed the discovery of [11C]SY-08, a new PET radiotracer that detects aggregated α-synuclein (α-Syn) fibrils in individuals with neurological disorders such as Parkinson’s disease, multiple system atrophy and dementia with Lewy bodies.
A biomarker found in spinal fluid can detect Parkinson’s disease in individuals with the disease and may flag those at risk years before symptoms develop, a study published in The Lancet Neurology found. The breakthrough, which could enable diagnosis of the disease for the first time in patients who do not exhibit a movement disorder, was achieved by an international coalition of scientists led by the Michael J. Fox Foundation (MJFF) as part of its landmark clinical study, the Parkinson’s Progression Markers Initiative (PPMI).
Alterity Therapeutics Ltd. has begun phase II trials with its lead candidate, ATH-434, in multiple system atrophy, a rare and highly debilitating Parkinsonian disorder.
Abbvie Inc. is stepping away from a 2016 deal with Bioarctic AB to develop alpha-synuclein antibodies for treating Parkinson’s disease, originally valued at up to $775 million. Bioarctic said it plans to stay the course without its big-pocketed partner. Bioarctic’s stock (Stockholm:BIOA-B) fell 14.6% to SEK90 (US$9.40) on April 20.
At the AD/PD 2022 international conference on Alzheimer’s and Parkinson’s Diseases, AC Immune SA presented images showing its positron emission tomography (PET) tracer detecting pathological alpha-synuclein (a-syn) in human subjects’ brains. The abnormal accumulation of a-syn, a natively unfolded and soluble presynaptic protein, is a neuropathological feature of neurodegenerative disorders.
Targeting the toxic alpha-synuclein protein found in the brains of people with Parkinson’s is one of the most promising approaches to treat the disease in the clinic – but getting any drug into the brain is a challenge. Sanofi SA has joined with ABL Bio Inc. to solve this problem, in-licensing ABL-301, a preclinical bispecific antibody that locks on to misfolded alpha-synuclein but also includes a molecular “shuttle” that allows it to penetrate the blood-brain barrier.

Cross-border startup Scineuro Pharmaceuticals Ltd., which focuses on central nervous system (CNS) diseases, inked a deal with Eli Lilly and Co. to license in the greater China rights of alpha-synuclein-targeted antibody therapies to follow the global drug development trend in this space.
Bold up-fronts and even bigger milestones defined ambitious neurology deals Abbvie Inc. struck with Voyager Therapeutics Inc. in 2018 and 2019. With vectorized antibodies, they planned to target multiple indications tied to excess aggregations of tau and tragic synucleinopathies. Considerable progress was made, said Omar Khwaja, Voyager's chief medical officer. But despite millions of dollars invested in the programs, Abbvie has now decided to quit the venture, leaving Voyager to either go it alone or find a new partner in its work on the challenging indications.
It has been more than 200 years since British doctor James Parkinson first identified the symptoms of a condition that he termed shaking palsy; unfortunately, there is still no cure to the disease that carries his name.
