After stroke, chondroitin sulfate proteoglycans (CSPGs) inhibit neuroblast migration and axon sprouting, but these effects can be blunted by modulating receptor-type tyrosine-protein phosphatase S (PTPsigma).
Data from preclinical studies conducted to examine the activities of the novel estrogen receptor beta (ERbeta) agonist EGX-358, previously under study for the treatment of hot flushes at Estrigenix Therapeutics, for the potential treatment of Alzheimer's disease (AD) were presented at the recent Alzheimer's Association International Conference.
Design Therapeutics has discovered conjugates consisting of a DNA-binding moiety capable of noncovalently binding to a nucleotide repeat sequence linked to a protein-binding moiety through an oligomeric backbone linker reported to be useful for the treatment of Friedreich ataxia.
Akili Interactive Labs Inc. has kicked off a phase III study of its digital treatment for children with attention-deficit/hyperactivity disorder (ADHD) living in Japan, the first pivotal trial of its video game-based cognitive treatment outside the U.S. Conducted by Osaka-based Shionogi & Co. Ltd., this marks the first pivotal trial of Akili’s video game-based cognitive treatment outside the U.S.
Cognetivity Neurosciences Ltd. is making progress in promoting its cognitive assessment tool as the brain health equivalent of a blood pressure check, following feedback from clinicians indicating the test could have broad applicability.
Beta-site APP-cleaving enzyme 1 (BACE1) inhibitors have a long history of failure in patients with Alzheimer’s disease. Clinical development of verubecestat, elenbecestat, lanabecestat, umibecestat, atabecestat and LY-3202626 were all discontinued. The drugs largely showed that inhibiting BACE1 reduced amyloid beta (AB) in both cerebrospinal fluid and plasma, reduced AB plaques on PET scans and reduced phosphorylated tau. Unfortunately, patients had early cognitive worsening, and there were signs of lowering of brain volume and increases in psychiatric adverse events.
Sosei Group Corporation and AbbVie have entered a new drug discovery collaboration and option-to-license agreement to discover, develop and commercialize small molecules that modulate novel G protein-coupled receptor (GPCR) targets associated with neurological disease.
During a presentation at the Alzheimer's Association International Conference 2022, researchers from the Genetic Frontotemporal Dementia (FTD) Initiative consortium presented data from a study following nearly 1,300 patients with FTD caused by a genetic mutation, their presymptomatic family members who have the inherited mutation and unaffected family members to serve as controls. Researchers have used data from the study, which has been enrolling patients for over 10 years, to develop biomarkers that can be used to assess progression of FTD in interventional clinical trials.
