A ketone body, a molecule derived from the metabolism of acids to obtain energy when glucose is not available, could become an effective ally in treating Alzheimer’s or preventing the effects of aging on the brain. A group of scientists at the Buck Institute for Research on Aging have studied the role of β-hydroxybutyrate (βHB) as a signaling metabolite of misfolded proteins by interacting with them and altering their solubility, a mechanism that allows their elimination, as observed in preclinical models.
Shares of Relmada Therapeutics Inc. (NASDAQ:RLMD) plummeted 77% to close at 63 cents Dec. 4 after a pre-planned interim analysis prompted the independent data monitoring committee to conclude the phase III Reliance II study testing REL-1017 in major depressive disorder is likely to fail, leaving the future of the NMDA receptor channel blocker in doubt while the company looks ahead to an earlier-stage psilocybin-based program targeting metabolic disease.
Beacon Biosignals Inc. can rest easy now that it has received U.S. FDA authorization of its predetermined change control plan for the Dreem 3s, a wearable sleep monitor that conducts electroencephalograms as users sleep. The authorization allows Beacon to incorporate updates to the Dreem 3S sleep-staging algorithm acquired through machine learning without submitting a new 510(k) application.
Spur Therapeutics Ltd. has selected SPR-301 as lead development candidate from its gene therapy program for a genetically defined subset of Parkinson’s disease characterized by mutations in the GBA1 gene. The mutations cause a deficiency in the enzyme glucocerebrosidase (GCase), leading to the accumulation of α-synuclein and subsequent death of neuronal cells that are hallmarks of Parkinson’s disease.
Switch Therapeutics Inc. has announced its first development candidate, a liver-sparing APOE (apolipoprotein E) RNAi therapy for treatment of Alzheimer’s disease in APOE4 carriers. Switch’s conditionally activated siRNA (CASi)-APOE program is designed to knock down APOE in the CNS without affecting APOE in the liver, where it plays a vital role in systemic lipid homeostasis.
Our immune cells are not just “defenders” against deadly viruses and pathogens but also a great balancer for tissue homeostasis. For neurological disorders, understanding the neuro-immune axis could be key to treating previously untreatable conditions such as autism spectrum disorder, according to Jun R. Huh, professor of immunology at Harvard Medical School.
In breaking news, Wave Neuroscience LLC received breakthrough device designation from the U.S. FDA for its magnetic electroencephalogram resonance therapy for adjunctive treatment of post-traumatic stress disorder (PTSD), making its technology the first medical device approved to treat the debilitating condition, the company said.
Researchers from Universita degli Studi di Pavia and Universita degli Studi di Torino have prepared and tested new boron-based compounds for the treatment of Alzheimer’s disease by capture-enhanced neutron irradiation (CENI).
Leal Therapeutics Inc. has divulged mitochondrial glutaminase kidney isoform (GLS, GLS1) inhibitors reported to be useful for the treatment of neurological and psychiatric disorders.
