Promis Neurosciences Inc. recently presented the rational design of an Alzheimer’s disease (AD) vaccine candidate maximizing the selective targeting of toxic amyloid-β oligomers.
Researchers from Violet Therapeutics Inc. presented the discovery of VTT-001, a novel EPHB3 inhibitor designed to target astrocyte-mediated disease mechanisms.
BHV-8000 from Biohaven Pharmaceuticals Inc. is a dual, brain-penetrant, oral small molecule that is highly selective against TYK2 and JAK1 enzymes, which are essential enzymes to the inflammatory response driving the progression of many neuroinflammatory and neurodegenerative diseases, such as Parkinson’s disease (PD).
Dravet syndrome (DS) is a rare and severe form of epilepsy that causes intellectual disability and motor deficits and can lead to premature death. A loss-of-function mutation in one copy of SCN1A, encoding the voltage-gated sodium channel (NaV)1.1 α subunit, is the most frequent alteration found in DS patients and has been linked with inhibitory neuron dysfunction. Despite the potential of gene therapies, AAV-mediated SCN1A gene replacement for DS has not been possible yet due to AAV genome size constraints.
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.
Xellsmart Biopharmaceutical (Suzhou) Co. Ltd. has announced IND clearances by the FDA for its XS-411 and XS-228 cell therapies, for Parkinson’s disease and amyotrophic lateral sclerosis (ALS), respectively.
Researchers from Eli Lilly & Co. reported preclinical data on LY-3954068, a MAPT small-interference RNA (siRNA) strategy in AD models. The therapy is designed to reduce tau protein synthesis by inhibiting the translation of MAPT mRNA, with the goal of effectively lowering all forms of tau.
Biohaven Pharmaceuticals Inc. has presented preclinical data on their novel bispecific degrader BHV-1310 for the potential treatment of autoimmune disorders. To date, about 10% of the global population is affected by autoimmune diseases. IgG-lowering agents have suboptimal pharmacology and pharmacodynamic effects and have safety and tolerability challenges.
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.
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.
