Long-term Survival Benefits of KEYTRUDA: New data from Merck's studies, presented at the ESMO Congress 2025, show that KEYTRUDA (pembrolizumab) combined with chemotherapy before surgery and as a single agent afterward significantly improves overall survival (OS) and event-free survival (EFS) in patients with resectable non-small cell lung cancer (NSCLC).
Sustained Efficacy in Advanced NSCLC: Eight- and ten-year analyses from various KEYNOTE trials indicate that KEYTRUDA monotherapy continues to enhance survival rates for patients with locally advanced or metastatic NSCLC, reinforcing its status as a standard treatment option.
Clinical Trial Insights: The exploratory five-year follow-up from the KEYNOTE-671 trial demonstrated a 64.6% five-year OS rate for the KEYTRUDA regimen compared to 53.6% for the chemotherapy-placebo regimen, highlighting the drug's effectiveness in earlier-stage NSCLC.
Merck's Commitment to Cancer Research: Merck is actively advancing research in lung cancer treatment, with a focus on improving outcomes through clinical trials and innovative therapies, aiming to transform the landscape of cancer care.

- Automotive Industry Cost Surge: Automakers such as General Motors and Toyota are facing tariff impacts estimated at up to $9.5 billion, and although the Trump administration has taken steps to alleviate overlapping tariffs, overall costs remain significant, forcing companies to reassess their supply chain strategies.
- Pharmaceutical Sector Stability: Pharmaceutical companies have secured three-year tariff exemptions through pricing agreements with Trump, although new tariffs impose 100% on companies that do not reach agreements, the overall industry is still striving to increase investments in U.S. manufacturing.
