Dendritic cells found to kill CD47-deficient T cells

Researchers at Kobe University discovered an entirely new and unexpected mechanism by which the immune system can get rid of cells lacking molecules that identify them as part of the self in mice. The finding, published in PNAS, has possible implications for cancer treatment. The immune system comprises many types of cells that work together to fight off diseases. Two important types are dendritic cells and T cells. Dendritic cells are located in strategic positions throughout the body including the gut and skin, as well as in the lymph nodes, sample their environment and present small components derived from these samples on their surface. T cells check these samples and if they recognize them as foreign (or “non-self”), they will initiate an immune response, otherwise they will move on. The ability to distinguish self from non-self is therefore a key characteristic of the immune system and T cells undergo very ...

Novo’s Wegovy Protects Heart Health in Overweight, Obese Adults

By Tristan Manalac Novo Nordisk’s weight-loss medication Wegovy (semaglutide) met its primary efficacy endpoint in the Phase III SELECT trial, demonstrating strong protective effect on cardiovascular health in overweight and obese adults without diabetes, the company announced Tuesday. At a 2.4-mg dose level, once-weekly Wegovy injections significantly reduced the occurrence of major adverse cardiovascular events (MACE) by 20% as compared with placebo. This treatment effect was statistically significant, according to Novo’s announcement. Wegovy’s safety profile in SELECT was also in line with what had been established in previous studies. SELECT defined MACE as a composite of cardiovascular death, non-fatal myocardial infarction or non-fatal stroke. Wegovy reduced the frequency of all three MACE components in SELECT. Novo was trading approximately 11% higher in pre-market Tuesday following the data drop. The results from SELECT highlight the potential dual benefits of Wegovy for overweight and obese adults who suffer from a heightened risk ...

Novavax Posts Surprise Q2 Profit, Hinges Hopes on Updated COVID Shot

By Connor Lynch Pictured: Gloved hand holding syringe in front of Novavax sign, Courtesy of rafapress/Getty Images Embattled vaccine maker Novavax is back in the black—at least, for now. In its second-quarter financial update Tuesday, the Maryland-based biotech posted a surprise $58 million in net income compared to a net loss of $510 million in the same period last year. Novavax reported second-quarter sales of $424.4 million, a significant increase from the expected $239.2 million in the quarter and $185.9 million during the same period in 2022. The latest update saw the biotech trim its full-year revenue forecast, but it is still anticipating between $1.3 and $1.5 billion in sales and grants, down from the $1.4 billion to $1.6 billion guidance provided in May. The company also entered into a stock purchase agreement with SK Bioscience, with Novavax issuing 6.5 million shares at $13 each to the South Korean company ...

Novo Nordisk posts ‘best-case scenario’ cardio outcomes data for star obesity drug Wegovy

Novo Nordisk has been riding the momentum of weight loss drug Wegovy ever since it stormed onto the market in 2021, creating widespread hype and even some supply shortfalls. But, now, a cardio outcomes trial could seriously change the game for the burgeoning medicine. In a large phase 3 trial, the drug cut the risk of major adverse cardiovascular events by 20% compared with placebo and standard of care, Novo said Tuesday. Specifically, investigators measured Wegovy’s 2.4-mg dose for its ability to cut the risk of a cardio death, heart attack or stroke. The trial enrolled 17,604 people and tested the drug for up to five years in people 45 and older who were overweight or obese and who had established cardiovascular disease. To be eligible for the trial, patients had to have had no history of diabetes. Based on the trial win, Novo Nordisk said it expects to seek ...

【EXPERT Q&A】Is it mandatory to conduct clinical trials for drug registration in India?

Drugdu.com expert’s response: Based on the years of experience from Drugdu.com, the number and cases of clinical trials conducted in India are related to the current clinical situation and whether the original research drug is marketed locally. Specific issues require case-by-case analysis. In general, for drug registration in India, if it is a chemical drug or a formulation, and the original research drug is already marketed in India, it can be registered as a generic drug in India, and clinical trials can be waived. Some orphan drugs, especially those that face recruitment challenges in clinical trials and are already marketed in the regulatory markets of Europe and the US, can also apply for exemption from local clinical trials. However, for biologics such as vaccines, monoclonal antibodies, and blood products, conducting phase III (bridging) clinical trials locally is mandatory for registration in India. Taking phase III clinical trials as an example, ...

Clinical Trials drug registration
analysts

Dive Brief Analysts at Needham expect a U.S. Food and Drug Administration advisory panel to support the safety and efficacy of Medtronic’s renal denervation device at a meeting later this month. The meeting, which the FDA scheduled in June, will enable experts in circulatory system devices to discuss the evidence on Medtronic’s Symplicity Spyral and ReCor Medical’s rival renal denervation system. While the analysts expect Medtronic to face questions over the failure of its pivotal trial, they think the experts will vote in favor of the device, putting it on track to target a $1 billion-plus market. Dive Insight Medtronic’s multi-year effort to build confidence in renal denervation as a way to treat high blood pressure hit a snag late last year when a pivotal trial found it worked no better than drugs alone at reducing patients’ blood pressure at home. However, while the missed endpoint was an unwelcome development ...

Out-of-pocket costs a barrier to treatment for opioid use disorder

Most individuals diagnosed with opioid use disorder are not on recommended medications and even fewer remain in care, according to a research letter published today in JAMA Internal Medicine by lead author Ashley Leech, PhD, assistant professor in the Department of Health Policy at Vanderbilt University Medical Center (VUMC). In 2021, there were more than 100,000 overdose deaths in the United States, with the highest rates among those ages 25-54. Just 22% of the 40,000 individuals with opioid use disorder studied by VUMC researchers continuously used buprenorphine for a full year. And among those who discontinued, many were on the medication for just over a month, which is markedly below recommended levels, the authors said. Stephen Patrick (MD, MPH, senior author, director Center for Child Health Policy at VUMC) said, “Treatment with medications like buprenorphine is safe and highly effective, reducing risk of countless adverse outcomes including overdose death. Nationwide, ...
