Fructose identified as central conduit to obesity

Researchers at the University of Colorado Anschutz Medical Campus have officially identified a central conduit to obesity: fructose. While fructose’s contribution to obesity is well-known, a study published today in Philosophical Transactions aggregates a large amount of work to make a full argument for how fructose drives obesity and diseases such as diabetes and fatty liver disease. “This is an in-depth review on a hypothesis that puts nature at the center of weight gain, examining how fructose works differently than other nutrients by lowering active energy,” says Richard Johnson, MD, professor at the University of Colorado School of Medicine and study lead author. “We determine a recently discovered function of fructose in survival that stores fuel in case resources become scarce. This is known as the ‘survival switch,'” he says. Fructose is the source of sweetness in fruit, but is primarily consumed in Western society as table sugar and high ...

Quest Launches Alzheimer’s Beta-Amyloid Blood Test for Consumers

By Tristan Manalac Monday, Quest Diagnostics launched the AD-Detect Test, a direct-to-consumer blood test designed to catch abnormal levels of the beta-amyloid protein to assess a patient’s risk of developing Alzheimer’s disease. According to Quest, AD-Detect is the first direct-to-consumer blood-based biomarker test for Alzheimer’s disease, though the company is quick to point out that it is not a diagnostic test. “Only a physician or healthcare professional can provide an Alzheimer’s disease diagnosis,” the company said in its announcement. “The risk of having Alzheimer’s disease as the underlying cause for mild cognitive impairment (MCI) or dementia should be considered in conjunction with the findings from medical and family history, physicals, nutritional deficiency biomarkers, neurological and neuropsychological examinations, and neuroimaging,” according to Quest. AD-Detect works by measuring two types of beta-amyloid biomarkers in the blood and determining the beta-amyloid 42/40 ratio, a validated tool used to assess a patient’s risk of ...

GSK’s Jemperli Beats Merck’s Keytruda for Frontline Endometrial Cancer Approval

By Tristan Manalac The FDA has approved GSK’s Jemperli (dostarlimab-gxly) for the treatment of primary advanced or recurrent endometrial cancer, the company announced Monday. The label expansion covers a combination regimen of Jemperli, carboplatin and paclitaxel, followed by Jemperli as a single agent. Monday’s approval also only applies to patients who are mismatch repair deficient (dMMR), as confirmed by an FDA-approved test, or who have high microsatellite instability (MSI-H). Jemperli is the first immuno-oncology treatment and PD-1 inhibitor to be authorized for frontline use in this patient population, according to GSK. The expanded approval “redefines the treatment landscape for patients with dMMR/MSI-H primary advanced or recurrent endometrial cancer,” for whom chemotherapy alone has been the standard of care, though many patients still see disease progression, Hesham Abdullah, GSK’s senior vice president and global head of oncology development, said in a statement. Jemperli is an anti-PD-1 antibody that was first approved ...

New study finds vaccines could avert 500,000 antimicrobial resistance deaths each year

A new study published in BMJ Global Health has revealed that over 500,000 deaths associated with antimicrobial resistance (AMR) could be averted each year with the effective use of existing vaccines and continued development of new vaccines to tackle priority pathogens. The modelling study, Global and regional burden of attributable and associated bacterial antimicrobial resistance avertable by vaccination, was carried out by the World Health Organization (WHO), the International Vaccine Institute, Korea (IVI) and the London School of Hygiene and Tropical Medicine. AMR occurs when bacteria, viruses, fungi and parasites change over time and become resistant to medicines. The condition has been declared by WHO as one of the top ten global threats to global public health, associated with around 4.95 million deaths globally per year. Science has been playing catch-up to mitigate AMR due to the strain that was faced by health systems worldwide throughout the COVID-19 pandemic. Using ...

As COVID revenues disappoint, once-high-flying Pfizer looks at possible cost cuts

As COVID-19 revenues ebb and flow—but mostly ebb—Pfizer is eyeing the cost-cutting shears. “Clearly, there is a higher level of uncertainty regarding the demand projections for our COVID-19 products than for the rest of our business,” Pfizer chief Albert Bourla, Ph.D., admitted on a conference call Tuesday. While the shift to a traditional commercial market for Paxlovid and Comirnaty could help, a veil of uncertainty persists. In turn, “we are also preparing to have the ability to adjust our 2024 total cost base” to align with future COVID needs, the CEO added. “In fact, we have already identified specific areas where we can make adjustments primarily within our COVID-19 cost base,” he said. Paxlovid generated just $143 million in worldwide sales for the second quarter, down 98% from the $8.1 billion it pulled down over the same stretch in 2022. MRNA vaccine Comirnaty, for its part, brought home $1.4 billion, ...

US DoD backs potential treatment for Fragile X-linked neurodegenerative disorder

The US Department of Defense (DoD) has awarded PureTech Health $11.4m to help target Fragile X-associated tremor/ataxia syndrome (FXTAS), a late-onset neurological condition that is difficult to diagnose and currently has no effective treatments. Based in Massachusetts, US, Puretech Health will use the funds to advance LYT-300 in a Phase II trial. LYT-300 is an oral prodrug of allopregnanolone, which is known to regulate mood via its positive allosteric modulation of gamma-aminobutyric-acid type A (GABAA) receptors. It is already approved by the US Food and Drug Administration (FDA) as an infusion treatment for postpartum depression. PureTech Health said administration limitations have previously restricted the wider use of the neurosteroid. Developed using the company’s Glyph platform that harnesses natural lipid absorption and transport processes, LYT-300 can be orally administered. FXTAS occurs in premutation carriers of Fragile X Syndrome. Estimates suggest that 30%-40% of male carriers, and 8%-16% of premutation carriers will ...

Integra warns impact of plant closure will continue into 2024, with delays possible

Dive Brief Integra LifeSciences is aiming to restart manufacturing at its Boston tissue product plant in the fourth quarter and resume commercial sales in the second quarter of next year, CEO Jan De Witte said in a Thursday earnings call. The forecast, which follows the recall of all devices made at the plant over the past five years, confirms that the problem will continue to drag on Integra’s results into next year. Further delays are possible. Integra expects the quality situation to wipe $60 million from its revenues this year, and predicts that it will take another $50 million sales hit next year. Dive Insight Integra disclosed the problems at its Boston plant in May. After discovering endotoxin testing deviations, the company recalled SurgiMend collagen matrix and other tissue devices made over a five-year period. Integra lowered its second quarter revenue forecast by $24 million and told ...

Non-profit receives FDA approval to supply cheaper OTC naloxone

The US Food and Drug Administration (FDA) approved the second over-the-counter (OTC) naloxone nasal spray product, RiVive (3mg) by non-profit pharmaceutical company Harm Reduction Therapeutics, for the emergency treatment of known or suspected opioid overdose. This approval follows the agency’s approval of Emergent BioSolutions’ Narcan in March 2023, as the agency has recently increased efforts to address the opioid crisis. The FDA also approved the first generic non-prescription naloxone drug in July 2023. Naloxone reverses opioid overdoses by blocking opioid receptors, thus preventing the drugs’ addictive effects. Harm Reduction Therapeutics has announced that the drug will be available by early 2024 and be primarily supplied to state governments and US harm organisations at “costs lower than other opioid antagonist nasal sprays”. The US-based non-profit organisation has said that the first 200,000 doses (10% of projected initial annual product production) of RiVive will be available free of charge. ...
