The U.S. government is advising that international travelers age 60 and older not get a chikungunya vaccine as it investigates possible side effects. The Centers for Disease Control and Prevention and the Food and Drug Administration posted notices late last week on the vaccine, Valneva’s Ixchiq. Chikungunya, spread by the bites of infected mosquitoes, is a debilitating tropical illness marked by fever and joint pain. About 100 to 200 cases are reported annually among U.S. travelers. Last year, the government began recommending the vaccine, which is made with weakened chikungunya virus, to U.S. adults who travel to countries where chikungunya is a problem. But last month, a panel of vaccine experts who advise the CDC heard about an investigation into six people 65 and older — most of them with other medical problems — who became ill with heart or brain symptoms less than a week after vaccination.

Recently, the annual meeting of the European Association for the Study of the Liver (EASL) is being held. At the conference, BoWang Pharmaceuticals presented the Phase I/IIa clinical research data of its innovative small interfering RNA (siRNA) therapy BW-20507 for the treatment of chronic hepatitis B (CHB) in a poster format. BW-20507 is a siRNA molecule targeting the S region of hepatitis B virus (HBV) messenger RNA developed by Bowang Pharmaceutical based on its independent RNAi platform and unique proprietary technology. This poster summarizes the key research data of BW-20507 monotherapy in the treatment of chronic hepatitis B patients with virological suppression and nucleoside (NUC) naive treatment: BW-20507, administered subcutaneously once every four weeks for three doses, significantly reduced HBsAg levels in a dose-dependent manner, with the maximum reduction observed in the 200 mg and 400 mg dose groups being 2.9~3.2 log10 IU/mL. Among subjects with baseline HBsAg levels less ...
On May 9, Johnson & Johnson announced that its blockbuster drug Guselkumab was approved by the National Medical Products Administration for the treatment of adult patients with moderately to severely active ulcerative colitis who have had an inadequate response, loss of response, or intolerance to traditional treatments or biologics. This event marks the official entry of interleukin 23 (IL-23) targeted era into the treatment of ulcerative colitis in China. 1. China’s first As the world’s first approved fully humanized IL-23 inhibitor, guselkumab (trade name: Tenoyada) precisely regulates the immune response through a unique dual mechanism of action: it not only directly binds to the IL-23 cytokine, but also targets IL-23-enriched CD64+ inflammatory cells, blocking this core pathogenic factor that drives immune-mediated diseases such as ulcerative colitis (UC) from the source. Today, guselkumab was officially approved by the China National Medical Products Administration for the treatment of adult patients with moderate ...

On Sunday evening local time, US President Trump announced on the social platform Truth Social that he will sign an executive order at the White House tomorrow morning at 9am (21:00 Beijing time on Monday). Prescription drugs and drug prices will almost immediately decrease by 30% to 80%, and the United States will purchase drugs at the lowest prices in the world. Trump said: For many years, the world has been puzzled: why are prescription drugs and medications priced much higher in the United States than in other countries? Sometimes, the same drug, produced by the same pharmaceutical company in the same laboratory or factory, can be sold for five to ten times more in the United States than in other countries! This question is always difficult to explain and awkward, because ultimately, there is no reasonable and legitimate answer. For many years, pharmaceutical companies have consistently stated that ‘research ...
New research being presented at this year’s European Congress on Obesity (ECO) in Malaga, Spain (11-14 May) reveals that adverse waist-to-height ratio trajectories (a marker for central obesity) during childhood may increase cardiometabolic and cardiovascular risk at 10 years old. Notably, children with gradually increasing central obesity from birth were more likely to show early signs of metabolic and cardiovascular risk by age 10. This included elevated blood pressure and higher levels of biomarkers linked to systemic inflammation and metabolic dysfunction, such as triglycerides, insulin resistance (HOMA-IR), glycoprotein acetyls (GlycA), and high-sensitivity C-reactive protein (hs-CRP). “With rapidly rising rates of childhood obesity worldwide, it is important to understand how central obesity during childhood is already linked to early signs of metabolic deterioration, including elevated blood pressure and circulating biomarkers associated with future cardiometabolic disease.” Dr. David Horner, lead author from the University of Copenhagen, Denmark. Obesity in childhood and ...
People taking Eli Lilly’s obesity drug, Zepbound, lost nearly 50% more weight than those using rival Novo Nordisk’s Wegovy in the first head-to-head study of the blockbuster medications. Clinical trial participants who took tirzepatide, the drug sold as Zepbound, lost an average of 50 pounds (22.8 kilograms) over 72 weeks, while those who took semaglutide, or Wegovy, lost about 33 pounds (15 kilograms). That’s according to the study funded by Lilly, which was published Sunday in the New England Journal of Medicine. Both drugs are part of a new class of medications that work by mimicking hormones in the gut and brain that regulate appetite and feelings of fullness. But tirzepatide targets two such hormones, known as GLP-1 and GIP, while semaglutide targets GLP-1 alone, said Dr. Louis Aronne, director of the Comprehensive Weight Control Center at Weill Cornell Medicine. “Two drugs together can produce better weight loss,” said Aronne, ...
