Stem cell implantation is a step closer to becoming the next strategy against Parkinson's disease. Two clinical trials, one in phase I and the other in phase I/II, have demonstrated their safety and potential to restore dopamine production in the brains of patients with this currently incurable neurodegenerative condition. The number of participants in the study is still small, and further research is needed to demonstrate the clinical benefits of these cell therapies.
Genes associated with lysosomal dysfunction increase the risk of Parkinson’s disease (PD), according to a study led by scientists at Northwestern University. The discovery also explains why some people who carry a pathogenic variant of the GBA1 gene develop PD or dementia with Lewy bodies (DLB) and others do not. The key lies in the Commander complex, involved in the transport of proteins to this organelle. This discovery raises the need for combinatorial therapies that act on more than one pathway for this type of neurodegenerative disorder.
After dropping development in December of its lead program, Spruce Biosciences Inc. has found new life by acquiring a BLA-ready enzyme replacement therapy for the rare genetic neurodegenerative disease Sanfilippo syndrome type B. If approved, the therapy, tralesinidase alfa, could bring Spruce a priority review voucher.
Scientists from the Machine Intelligence from Cortical Networks (MICRONS) consortium have published the microconnectome of a cubic millimeter of the mouse brain. This is the most complete map of this organ to date at nanometer resolution for a mammal. It not only contains the structure and connections of each and every cell in that volume of tissue, but is also linked to the neuronal activity of that portion of the CNS, linking anatomy and function in the same cells.
Tryptamine Therapeutics Ltd. is gearing up to enter the clinic with lead compound TRP-8803, an intravenous-infused psilocybin therapy, in patients with binge eating disorder in conjunction with psychotherapy.
Alzheon Inc.’s oral treatment for people in the early stages of Alzheimer’s disease missed its phase III primary endpoint, adding yet another therapy to a long list by many developers that can’t beat dementia. The study also received grant money, which is in increasingly short supply.
The current treatment strategies for neurodegenerative diseases focus on targeting Aβ in Alzheimer’s disease (AD), α-synuclein aggregates in Parkinson’s disease (PD) and anti-tau therapies, which are primarily used in AD but are also being explored for PD. At the 2025 International Conference of Alzheimer’s & Parkinson’s Disease and Related Neurological Disorders, Aditya Iyer, senior RD scientist from Amyl Therapeutics Srl, presented data on an option which could potentially serve as a pan-amyloid therapeutic.
As developers continue to search for better amyotrophic lateral sclerosis (ALS) therapies, Neurosense Therapeutics Ltd. turned up some hopeful findings from its phase IIb Paradigm trial with PrimeC. The drug, a combination therapy (ciprofloxacin and celecoxib) designed to target multiple ALS pathways, is having salutary effects on microRNA modulation (miRNA), Neurosense said, with the study showing a “profound and consistent” downregulation of 161 mature miRNAs across all time points in the double-blind period of the experiment.
Remegen Co. Ltd. emerged as a surprise challenger in the generalized myasthenia gravis space, unveiling positive phase III data of its China-approved lupus drug, telitacicept (RCT-18; Tai’ai), in the rare autoimmune neuromuscular disorder at the 2025 American Academy of Neurology conference.
China approved 48 first-in-class innovative drugs, as well as a significant number of medications for pediatric and rare diseases, thanks to measures aimed at enhancing review efficiency and accelerating patient access to novel therapies, according to a report released by China’s National Medical Products Administration.
