Keytruda headlines this week as researchers show a personalized cancer vaccine combo halting melanoma relapse; Merck expands U.S. presence with a new biologics plant.
Two unvaccinated residents in Pennsylvania have died from measles, triggering a public health debate. Governor Shapiro says vaccinations could have averted the deaths, while RFK Jr. questions the figures, fueling a political row that experts warn could hinder responses to the outbreak.
The experimental mRNA cancer vaccine, intismeran, has been tested in a phase 3 trial with 1,000+ melanoma patients. It is personalised to each patient by analysing tumors and targets neoantigens. When given with pembrolizumab, it aims to boost the immune response and extend cancer-free time. Results indicate reduced recurrence risk, but long-term survival remains to be seen. Trials also explore other cancers.
This week has seen several medical research and regulatory developments. Insilico Medicine has reported that its experimental drug rentosertib changed blood‑protein patterns that aging clocks read as three to four years younger in a small trial. Stanford teams have published studies showing they can grow hindbrain neurons separately and implant human cortical organoids into mice. The US health department has appointed permanent directors for three FDA centers.
