The positively charged nanoparticle polyamidoamine generation 3 (P-G3) can be specifically targeted to either visceral or subcutaneous fat, and affects both types of fat in different ways, researchers from Columbia University reported in two papers recently published. The studies, published online in Nature Nanotechnology on Dec. 1, 2022, and in Biomaterials on Nov. 28, 2022, are both “a conceptual advance” and “quite amenable to translation,” co-corresponding author Kam Leong told BioWorld.
Neurons are specialized cells with a high metabolic demand to fulfill their function, survive or keep a healthy half-life. In this sense, the anabolism and catabolism of proteins and lipids could be associated to different neurodegenerative diseases. At the 2022 annual meeting of the Society for Neuroscience, scientists reported the latest discoveries on neuron metabolic needs at a session on 'Powering Thoughts: The Regulation of Neuronal Energy Metabolism and Mitochondria.'
Ardelyx Inc. could have a rocky row to hoe when it makes its case for tenapanor, as a hyperphosphatemia therapy in adults with chronic kidney disease, before the U.S. FDA’s Cardiovascular and Renal Drugs Advisory Committee Nov. 16. The big question facing the adcom is whether the change in baseline serum phosphorous levels achieved by the drug is clinically meaningful. Clearly, FDA reviewers don’t think so, as that question already has resulted in delayed PDUFA dates, a complete response letter and two formal dispute resolution requests.
Minoryx Therapeutics SL is banking what it described as “a significant double-digit up-front payment” and could earn up to €258 million (US$262.1 million) more in milestone payments and development funding from a license agreement with Neuraxpharm GmbH, which covers European rights to its lead drug candidate, leriglitazone, in central nervous system indications. It will also receive tiered double-digit royalties on product sales.
Innovent Biologics Inc. said that, compared to a placebo, both doses of its anti-PCSK-9 monoclonal antibody tafolecimab tested in a phase III trial “yielded significant and durable reductions” in low-density lipoprotein cholesterol levels and showed a favorable safety profile in Chinese patients with non-familial hypercholesterolemia.
Bloomsbury Genetic Therapies Ltd. has raised £5 million (US$5.5 million) in a seed round, to take four gene therapy programs based on research carried out by the scientific founders at University College London into clinical development.
Investigators at Washington State University (WSU) have identified a set of eight proteins that were expressed in the serum of Ursus arctos horribilis, better known as the grizzly bear, specifically during their hibernation period. In addition to reporting new basic insights into hibernation, the study, which was published in the Sept. 21, 2022, issue of iScience, could also give clues to insulin resistance and its relationship to body fat.
Bearish investors dwelling on a single grade 4 liver enzyme elevation seemed to be the cause for Intellia Therapeutics Inc.’s sinking stock Sept. 16, despite the company reporting impressive, though early stage, data for its leading systemically administered CRISPR candidates targeting hereditary angioedema (HAE) and amyloid transthyretin (ATTR) amyloidosis.
Sex differences at the cellular level could explain why men respond less well to glioblastoma (GBM) treatments, according to a study led by the Washington University School of Medicine in St. Louis (WUSTL). The researchers found that male and female GBM tumor cells had different metabolic needs. GBM cells from male surgical samples absorbed more glutamine and had different nutritional preferences for amino acids.
The bad news in March 2022 from Takeda Pharmaceutical Co. Ltd. regarding Natpara, its recombinant human parathyroid hormone for hypoparathyroidism (HPT), served to generate more interest in the already bubbling space, where a handful of players large and small own prospects at various clinical stages.
