Merck proves out new version of Keytruda in study
A new formulation of the best-selling cancer drug, Keytruda, appears to deliver similar blood levels of the medicine when it is given as a shot as when it is given intravenously, Merck reported Tuesday.
For Merck, the new under-the-skin, or subcutaneous, formulation of Keytruda could represent a major way of holding on to a larger share of Keytruda’s $25 billion in annual sales than would otherwise occur when the medicine’s U.S. patent expires in 2028.
The subcutaneous injection could be given in a doctor’s office every six weeks, instead of requiring a 30-minute IV drip at the same interval. Analysts expect that Merck might be able to continue to charge a higher price for the in-office version while competition from biosimilar medicines pushes down the price for Keytruda’s existing formulation.

Global reach is lacking for many pharma companies
Although some pharma companies are trying to improve drug access in low- and middle-income countries, the progress overall is pretty lackluster. The number of licensing deals, tech transfers, and clinical trials in these regions are pretty limited — and most programs aren’t particularly transparent, STAT’s Ed Silverman writes.
“Since we began measuring these companies, we expected the pace of progress would pick up, but it’s falling short — and not a little bit short, but a lot short,” said Jayasree Iyer, head of the Access to Medicines Foundation that presented these findings. “The big concern is how do we keep momentum going if, in fact, it’s dropping down?”

What the cardiologists were talking about at AHA
This year’s American Heart Association conference spent a good chunk — predictably — on obesity drugs like tirzepatide and semaglutide, featuring groundbreaking trials on their impact in heart failure and cardiovascular risk reduction. Other key studies included intensive blood pressure management in type 2 diabetes, as well as novel approaches to treat transthyretin amyloidosis using CRISPR-based and RNA therapies.
Heart rhythm disorder treatments, AI-powered echocardiogram diagnostics and reconditioned pacemakers for underserved populations were also discussed during the conference. There was discussion, too, of how the overall cardiovascular disease burden will worsen from now until 2050.
“We have a problem,” former AHA president Valentin Fuster said. “Pay attention to health and prevention — that is the challenge of the next century.”
