- China approved Amgen's tarlatamab for hard-to-treat lung cancer.
- The drug targets adults with small cell lung cancer resistant to chemotherapy.
- Tarlatamab could generate over $2 billion in annual sales for Amgen.

Amgen's targeted immunotherapy, tarlatamab, has received approval from China's National Medical Products Administration. This development was announced by its partner, BeOne Medicines.

While launch details and pricing for the Chinese market remain undisclosed, analysts project tarlatamab could achieve annual sales surpassing $2 billion for Amgen.
