Artificial sweeteners linked to increased body fat, study finds

Published in the International Journal of Obesity, University of Minnesota Medical School and School of Public Health researchers led a study on the relationship between dietary intake and cardiovascular disease risk factors. Over 20 years, the research team examined people’s regular dietary intake, paying particular attention to non-nutritive sweeteners commonly found in artificial sweeteners. They found that long-term consumption of aspartame, saccharin, and diet beverages were linked to increased fat stores in the abdomen and fat within muscle. However, the study found no significant association between the artificial sweetener sucralose and these measures of fat volume. Brian Steffen (PhD, MSCR, Professor, Department of Surgery, University of Minnesota Medical School) said, “This study showed that habitual, long-term intake of total and individual artificial sweetener intakes are related to greater volumes of adipose tissue, commonly known as body fat. This was found even after accounting for other factors, including how much a ...

New technique enables high-resolution analysis of DNA

Function and form are deeply intertwined in biology. Knowing how organisms grow, adapt and reproduce requires understanding their physical structures. Hence the transformative power of the microscope across the past four centuries of science. Microscopy, or the field of microscope use, can now reveal the tiniest of structures through techniques such as microcrystal electron diffraction, or MicroED. Instead of passing light through a cell like an optical microscope, MicroED bombards crystalline samples with a stream of electrons to produce detailed information about their atomic configuration. Brent Nannenga (Associate Professor, Chemical Engineering, Arizona State University) said, “The method was developed to reveal or ‘solve’ the structure of proteins. Then researchers started applying it to compounds for pharmaceuticals and small organic molecules. However, it had not been demonstrated for nucleic acids, and the scientific community was asking whether it would work for DNA.” Nannenga and colleagues just answered that question. A research ...

Bavarian Nordic locks up $120M BARDA deal to replenish US stock of smallpox, mpox vaccine

After coming to the rescue during the mpox outbreak in 2022, vaccine maker Bavarian Nordic has agreed to help replenish U.S. stores of its smallpox/mpox shot. The U.S. Biomedical Advanced Research and Development Authority (BARDA) is handing Bavarian Nordic a new $120 million contract, primarily to cover the production of new bulk vaccine product, the company said in a press release Thursday. The bulk product order represents $96 million of the contract value. That portion will be manufactured and invoiced in 2023 and will “only partly restore the inventory,” Bavarian Nordic said. Bavarian Nordic will also manufacture and supply an additional $3 million worth of liquid-frozen doses in 2023. The rest of the contract will cover “additional services” totaling $21 million, with Bavarian Nordic getting its hands on most of that sum over the next two years. Throughout 2022 and 2023, Bavarian Nordic says it’s manufactured around 5.5 million smallpox/mpox ...

Novo Nordisk, Eli Lilly face injury lawsuit from user of popular GLP-1 medicines

As Novo Nordisk and Eli Lilly rack up significant sales from their GLP-1 diabetes and obesity drugs, the companies also must gear up for defense against lawsuits from new users. Case in point is a claim from a Louisiana woman who is suing both companies, alleging her use of Novo’s Ozempic (semaglutide) and Lilly’s Mounjaro caused her to vomit so much that some of her teeth have fallen out. Jaclyn Bjorklund, 44, who used Ozempic for more than a year and then switched to Mounjaro, says the companies failed to warn patients of “severe gastrointestinal events” that can be caused by using the injected drugs. The lawsuit claims that Bjorklund has suffered from “severe vomiting, stomach pain, gastrointestinal burning,” and has been hospitalized for stomach issues on “several” occasions. The prescribing labels for Ozempic and Mounjaro say the drugs “delay gastric emptying” and warn of the risk of gastrointestinal adverse ...

GSK files lawsuit against Pfizer over RSV vaccine patent infringement

GSK has sued Pfizer in a US court, alleging infringement of the patents it holds on vaccines for respiratory syncytial virus (RSV). The lawsuit claims that Pfizer’s Abrysvo infringes on four of GSK’s patents that cover its rival vaccine, Arexvy. In May, Arexvy became the first RSV vaccine to be approved anywhere in the world after it received approval from the US Food and Drug Administration (FDA). The US approval of Pfizer’s vaccine followed shortly afterwards. RSV is a common contagious virus characterised by several mild, cold-like symptoms. Although most people can recover within a week or two, older adults are at a high risk for severe disease. Both companies’ vaccines aim to prevent lower respiratory tract disease caused by RSV in individuals aged 60 years or older and are expected to be available in the US before the next RSV season. A GSK spokesperson said that “intellectual property protections ...

NICE publishes draft guidance not recommending CSL’s haemophilia B gene therapy

The National Institute for Health and Care Excellence (NICE) has issued a draft Appraisal Consultation Document that does not recommend CSL Behring’s Hemgenix (etranacogene dezaparvovec) gene therapy for haemophilia B. The company has been seeking approval for use of the therapy in adults with severe or moderately severe haemophilia B without a history of factor IX inhibitors. In its guidance, NICE’s evaluation committee said that while there is clear evidence that the therapy reduces the number of bleeding episodes haemophilia B patients have each year, there is not enough evidence on how well it works in the long term, meaning cost-effectiveness estimates are “uncertain”. It also cited problems with the indirect comparison between the gene therapy and factor IX replacement therapies. Haemophilia B is a genetic bleeding disorder resulting from missing or insufficient levels of blood clotting factor IX, a protein needed to produce blood clots to stop bleeding. Patients ...

With Takeda and Hutchmed hot on the trail, Taiho wins FDA nod for stronger Lonsurf regimen in colorectal cancer

Eight years after an initial FDA approval in heavily pretreated colorectal cancer, Taiho Oncology’s Lonsurf has won another green light in the same indication but as part of a more powerful regimen. Instead of a single-agent regimen, the FDA on Wednesday cleared Lonsurf to be used alongside bevacizumab for previously treated metastatic colorectal cancer. Patients who have tried an anti-VEGF inhibitor such as bevacizumab—originally developed by Roche as Avastin—may also qualify for this new combo. The Lonsurf-bevacizumab cocktail proved to be more efficacious than Taiho’s drug alone. Compared with Lonsurf monotherapy, the new combination significantly reduced the risk of death by 39% in a group of patients who had previously received a maximum of two prior chemotherapy regimens and an anti-VEGF agent, plus, in some cases, an anti-EGFR therapy such as Eli Lilly’s Erbitux. In that phase 3 trial, patients who received the combo lived a median 10.8 months, while ...

Liquid biopsy may be used to identify gene mutations in pediatric arteriovenous malformations

A study presented today at the Society of NeuroInterventional Surgery’s (SNIS) 20th Annual Meeting indicated that it may be possible to use a less invasive technique to identify the gene mutations responsible for some arteriovenous malformations (AVMs) in pediatric patients. AVMs, including vein of Galen malformations, which are usually diagnosed soon after birth, are tangled blood vessels that disrupt blood flow and oxygen circulation, and are most often found in the brain and spinal cord. These vessels can rupture and cause brain hemorrhage, stroke, and brain damage for children and adults. Many complex AVMs in children are caused by a few specific gene mutations, but it’s difficult to find out which mutation is responsible (and, therefore, which treatment to use) without taking a surgical biopsy of the AVM. A surgical biopsy comes with a risk of brain bleeding. As a result, researchers in Australia opted to try using “liquid biopsy”-;taking ...

Scleroderma Research Foundation launches clinical trial platform to advance treatments

The Scleroderma Research Foundation (SRF) has announced the launch of a new clinical trial platform aimed at advancing treatments for the rare autoimmune disease of the skin and organs. Using a model created over a decade ago to accelerate oncology drug development but not previously used for autoimmune disorders, the CONQUEST platform is designed to identify agents that are ready to progress from phase 2b to phase 3 clinical trials. The initiative, conceived and led by the SRF, will initially focus on interstitial lung disease secondary to scleroderma but will be expanded in the future to address other manifestations of the disease. The first iteration, which is expected to begin in the fourth quarter of this year, will include approximately 400 patients and will test two drugs, including one from Sanofi. The trial will measure forced vital capacity, the total volume of air that can be exhaled during a maximal ...
