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.
Boston Scientific Corp.’s image-guided programming software, Vercise Neural Navigator with Stimview XT, got the green light from the FDA for use with the company’s deep brain stimulation (DBS) portfolio in patients with essential tremor or Parkinson’s disease. The software, developed in a collaboration with Brainlab AG, provides more sophisticated image-guided programming tools for personalization of the stimulation therapy, halving the time needed for adjustments and increasing precision.
A research team from the Grenoble Institute for Neuroscience (GIN) recently discovered a blood biomarker capable of detecting the onset of Parkinson's disease (PD) from a very early stage. This discovery represents the findings of a multi-model, translational study published in the Journal of Clinical Investigation.
Neuron23 Inc. came out of stealth mode in late 2020 with a $113.5 million combined series A and B round to support its AI-enabled drug discovery effort aimed at bringing a precision medicine approach to neuroimmunology. Now it has added another $100 million in a series C financing as it gears up to move into clinical testing with lead programs targeting LRRK2 and TYK2.
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.
New data from two phase II studies from two companies showed progress in their respective Parkinson’s disease programs. The data for both therapies, from Anavex Life Sciences Corp. and Sage Therapeutics Inc., were presented on opening day, March 15, at the AD/PD 2022 Advances in Science & Therapy International Conference on Alzheimer’s and Parkinson’s Diseases and Related Neurological Disorders, being held in Barcelona until March 20.
Sio Gene Therapies Inc. is retrenching the business as it terminated the company’s AXO-Lenti-PD license agreement with Oxford Biomedica plc for treating Parkinson’s disease. Also, Sio’s CEO, Pavan Cheruvu, is leaving the company. Sio said it is deprioritizing its Parkinson’s disease program due to several factors, including resource requirements and development timelines “to reach meaningful value inflection for the program and an increasingly challenging market and regulatory environment” for the indication.
Several pharma companies think that targeting a rogue protein known as alpha-synuclein could be the key to halting or reversing neurodegeneration in Parkinson’s disease – but has the industry learned from a string of failures in Alzheimer’s? In the space of a few weeks, Novartis AG and Sanofi AS have signed major deals for molecules targeting misfolded alpha-synuclein, the rogue protein thought to be the root cause of Parkinson’s disease.
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.
