Is cemiplimab a targeted drug?

Cemiplimab (Cemiplimab) Although not a targeted drug in the traditional sense, it can be classified as an immunotherapy drug that acts on specific molecules of the immune system to enhance the immune response to cancer. Immunotherapy is a type of targeted cancer treatment that aims to restore or enhance the function of the immune system so that it can more effectively recognize and destroy cancer cells.

The mechanism of action of cimipilimab is to enhance the activity of the immune system by blocking the binding of the PD-1 (programmed death -1) receptor to its ligand PD-L1 (programmed death ligand 1). Although it does not directly interfere with the growth signaling pathways of cancer cells like traditional targeted drugs, it is a drug that targets immune checkpoints. Immune checkpoint is a biological regulatory mechanism in the immune system that is used to prevent excessive immune responses and maintain the balance of the immune system. However, some cancers exploit this mechanism to evade immune system attack. Cimepilimab works by relieving the inhibition of PD-1/PD-L1 communication and activating the immune system so that it can more effectively recognize and attack cancer cells.

Immunotherapy drugs like cimepilimab are leading a new direction in cancer treatment because they target specific molecules in the immune system rather than directly intervening in the growth of cancer cells. This treatment strategy has achieved remarkable success in some types of cancer and offers new hope for patients who are insensitive to or poorly tolerated by traditional treatments. So while cimepilimab is not a traditional targeted drug, it is a drug that targets the immune system and has revolutionary therapeutic potential.

Cimeplimab is not currently available in China, so patients cannot purchase it domestically and need to purchase cimeplimab through overseas channels. There are only cimepri monoclonal original drugs abroad, mainly European and American versions. The European version is about 40,000, and the American version is about 100,000. Both are original drugs, and their drug ingredients and efficacy are the same.
