Functional Cure for Hepatitis B Sharply Drops Liver Cancer Risk

Summary

For people living with chronic Hepatitis B, doctors often look for a specific medical milestone known as the loss of the Hepatitis B surface antigen. This antigen is a viral marker found in the blood, and when it disappears, medical professionals consider the patient to have achieved a functional cure. A recent study tracked 15,760 patients in the United States with chronic Hepatitis B to see how reaching this milestone affects their long-term health. Over the course of the study, about 4.2 percent of these individuals experienced this functional cure.

The health benefits for those who cleared the antigen were striking. Patients who achieved this functional cure saw an 89 percent drop in their risk of developing hepatocellular carcinoma, which is the most common type of liver cancer. Furthermore, their risk of death from any cause fell by 62 percent. The researchers also noticed lower risks for other severe liver conditions like cirrhosis, though these specific reductions were not mathematically large enough to completely rule out statistical chance.

Why it matters.

These findings offer an encouraging message for patients living with chronic Hepatitis B, proving that achieving a functional cure translates directly into cancer prevention and a longer life expectancy. Demonstrating these results in a diverse American population reinforces the value of current treatments and gives the medical industry a clear, highly impactful target for the next generation of antiviral drugs.

However, there are a few caveats to keep in mind. The findings are based on a retrospective look at electronic health records rather than a controlled, real-time clinical trial. The study also specifically excluded patients who already had advanced liver disease or who were simultaneously infected with HIV or other forms of hepatitis. Despite these limitations, the dramatic 89 percent reduction in liver cancer risk provides incredibly compelling evidence that clearing this viral marker changes lives.

Maryland sets a $274 monthly price cap on the diabetes drug Ozempic

The state of Maryland is taking a major step to rein in the cost of prescription medications. The Maryland Prescription Drug Affordability Board recently decided to set a strict price limit on Ozempic, a widely used treatment for type 2 diabetes. By establishing what is known as an upper payment limit, the board aims to make the medication more affordable for state budgets. Under this new rule, the cost of Ozempic will be capped at $274 for a standard 30-day supply. To come up with this number, the board looked at the maximum fair price that Medicare currently pays for the drug and used it as a benchmark. State officials estimate that this single price cap will save Maryland about $5.8 million every year. However, everyday consumers will not see these savings immediately. The initial price cap is slated to take effect in January 2027, and it will strictly apply to state and local government health plans. This means the immediate financial relief is limited to public programs rather than individual pharmacy visits for the general public.

FDA shakeups, safety warnings, and a promising obesity pill

The Food and Drug Administration is navigating major leadership transitions, with acting directors Tracy Beth Høeg and Katherine Szarama recently exiting their roles in top drug review offices. Amidst these changes, the agency is facing severe safety concerns regarding Tavneos, a rare disease medication from the pharmaceutical company Amgen. In Japan, twenty patients taking the drug have died, with most of these deaths linked to a severe liver condition called vanishing bile duct syndrome. Following these tragedies and allegations of manipulated clinical trial data, the FDA has asked Amgen to withdraw the drug in the United States, though it currently remains available on the market. In other medical developments, an experimental daily pill for obesity is showing significant promise. Vincentage Pharma reported that patients taking its drug VCT220 in a late-stage Chinese clinical trial lost about twelve percent of their body weight over a year, compared to just one percent for those taking a placebo. However, the drug is still experimental globally, and a broader Phase 2 study is underway with results not expected until late 2026. Meanwhile, the major drugmaker Regeneron has teamed up with an early-stage startup called Parabilis Medicines. They plan to develop new therapies known as "antibody-helicon conjugates," which are designed to reach and treat disease-causing proteins inside cells that conventional methods have traditionally found impossible to target.

Physical decline starts at 35, but late-in-life exercise boosts fitness

A massive study tracking people in Sweden for almost 50 years has pinpointed exactly when our bodies start to lose their physical edge. Researchers discovered that overall fitness, physical strength, and muscle endurance quietly begin to slip around age 35. Rather than maintaining a slow and steady pace, the researchers noted that the rate of this physical decline actually speeds up as the years go by. However, the study offers a highly encouraging twist for older adults. Even if someone has been inactive for decades, deciding to adopt a physically active lifestyle later in life can still yield major benefits. The researchers found that these late starters actually improved their physical performance by up to 10 percent, proving that the human body remains responsive to exercise well into old age. While tracking individuals over a five-decade span is a remarkable scientific achievement, there are a few limitations to keep in mind. The research is based entirely on a Swedish cohort, so it is unclear if these exact timelines apply to more diverse global populations. Additionally, the initial data does not specify the exact number of participants or the specific medical tests used to measure their fitness levels.
