AI Summary
The International Consortium of Investigative Journalists (ICIJ) revealed how Merck & Co. employed aggressive tactics to inflate prescriptions and maintain high prices for its anti-cancer drug, Keytruda, making it unaffordable for many worldwide. Merck CEO Robert M. Davis, whose company generated $31.7 billion in Keytruda sales in 2025, supported President Donald Trump's drug price deals in December 2025 but did not commit to cutting Keytruda's cost. The investigation found Merck exploited the patent system with 1,212 patent applications to extend its market dominance for 14 years after original patents expire in 2028. Merck also promoted a higher-than-necessary dosage, which could cost $5 billion for lung cancer patients by 2040, and funneled nearly $75 billion in dividends to shareholders. Governments globally, including the UK's NHS and nations like South Africa and Guatemala, face strained budgets and limited access due to Keytruda's high prices, which range from $80,000 in Germany to $208,000 in the U.S.
What's Being Done
The International Consortium of Investigative Journalists (ICIJ) conducted an investigation into Merck's practices.
