With Keytruda's patent expiring in 2028, multiple pharmaceutical companies including Samsung Bioepis, Formycon, Zydus, Celltrion, and Amgen are advancing biosimilar candidates, aiming to capture the market. Merck (MSD) is defending its market share by introducing a subcutaneous formulation of Keytruda, leveraging new technology to improve patient convenience and speed of administration.

This Wire brief sits within Fusion42's coverage of Biotech, and 2 sources have reported it.

◆ ◆ The Wire takeaway

You now face a market where speed and fewer clinical trials can win approval for biosimilars; cut development time like Formycon to get ahead of your rivals. MSD’s switch to a subcutaneous version means your biosimilar must offer clear benefits to compete on convenience, not just price.
