Roche to test if new drug can prevent Alzheimer's disease, Bloomberg News reports

Reuters27-07-2025
July 27 (Reuters) - Swiss drugmaker Roche Holding (ROG.S), opens new tab plans to test whether an experimental medicine can prevent Alzheimer's disease symptoms in high-risk people, Bloomberg News reported on Sunday.
The new late-stage study will target people who are at risk of cognitive decline and aim to slow down the emergence of symptoms or prevent them fully, the report said, citing a statement.
The new pre-clinical study is the third largest late-stage trial that the company has announced for its drug trontinemab, which uses an experimental technology called brain shuttle to ferry medicine past the protective blood-brain barrier, according to the report.
Rivals like Eli Lilly (LLY.N), opens new tab have been making progress in the complicated field of Alzheimer's recently with Lilly's Alzheimer's drug Kisunla getting recommendation from the European Medicines Agency (EMA) last week.
Reuters could not immediately verify the report. Roche did not immediately respond to a request for a comment.
Treatments for Alzheimer's approved so far, including Eisai (4523.T), opens new tab and Biogen's (BIIB.O), opens new tab Leqembi, and Eli Lilly's Kisunla, are designed to clear sticky clumps of a protein called amyloid beta in the brain. They also carry hefty price tags and the risk of serious brain swelling and bleeding.

I am injecting my 13-year-old daughter with fat jabs. This is why I did it, the incredible impact it's already had and why hundreds of parents will follow in my footsteps

Tomorrow evening, just as she has done for the last eight months, Sarah Masterman* will take a small syringe into her 13-year-old daughter Bella's bedroom and swiftly inject medication into one of her thighs. The mother of three is happy to describe this weekly ritual as little short of a lifesaver, although it is not vital emergency medicine that Sarah is administering to her young daughter's body. It is the GLP-1 drug semaglutide, a weight-loss aid better known by brand names such as Ozempic and Wegovy. Teenage Bella is certainly a success story on that front: since Christmas, she has lost three stone, dropping from 11st 7lbs to just over 8st.

Hundreds more may have died in LA's devastating fires in January than first reported, study finds

The death toll from the devastating early January wildfires around Los Angeles may be more than 400 people greater than the official tally, according to a new study. The paper, published by Finnish researchers in an American Medical Association journal, looked at the difference between expected and observed deaths in Los Angeles County as the fires were burning and found 440 excess deaths. They attribute the excess deaths to health conditions made worse by wildfire smoke, as well as mental health issues and health interrupted by the blazes, among other factors. 'The findings from this study underscore the need to complement direct fatalities estimates with alternative methods to quantify the additional mortality burden of wildfires and of climate-related emergencies more broadly,' the authors wrote. 'They also highlight the need for improved mortality surveillance during and after wildfire emergencies.' The study got the attention local leaders, who are still rebuilding after the Palisades and Eatons fires destroyed more than 16,000 structures and were attributed directly to 31 deaths. L.A. County Supervisor Kathryn Barger, whose district includes the hard-hit Altadena area, said she had seen the study's findings with interest. 'This study's assertion that over 400 excess deaths are a result of our Los Angeles wildfires is concerning,' she told the local Daily Breeze newspaper. 'In response, I've asked our county's Department of Public Health to thoroughly review the findings and provide their input. It is critical that we understand the full scope of the wildfires' impacts.' Another group of recent studies looked at similar indirect impacts from the 2023 Maui wildfire. The Maui fire was directly blamed for more than 100 deaths. But it also left 1 in 5 with lung damage and as many as half with symptoms of depression, one set of new research found. The month of the fire saw 13 suicide and overdose deaths, translating to nearly double the normal suicide and overdose death rates. Jonathan Purtle of New York University was the lead author of one study, which calculated rates of suicide and overdose deaths in Maui and Hawaii's four other counties. That research team found a 97% increase in suicides and overdose death rates on Maui during the month of the wildfires. The total number of suicide and overdose deaths was 13 that month — most of them suicides. They also found a 46% increase in such deaths in all five counties, which may have been influenced by displaced Maui residents migrating to other islands, the authors said. The increases did not last: Rates fells in the following months, the researchers found.

Study reveals health risks of excessive screen time in teens

Excessive screen time in children and young adults significantly increases the risk of heart-related health conditions such as high blood pressure, high cholesterol, and insulin resistance. Danish researchers found that this link is particularly strong in individuals who experience reduced sleep, suggesting screen use may be displacing crucial sleep time. The study, involving over 1,000 Danish youths, revealed that each additional hour of screen time daily worsened cardiometabolic risk, with three extra hours leading to a notable increase. Machine learning identified a 'screen-time fingerprint' in blood samples, indicating biological changes that could signal long-term heart health risks from early screen habits. Experts recommend gradually reducing screen time, particularly by shifting screen use earlier in the day and prioritizing earlier and longer sleep, to mitigate these health risks.
