What are the treatment cycles?

IMFINZI and chemotherapy* infusions are given in cycles. IMFINZI is given with chemotherapy* both before and after surgery, followed by IMFINZI alone. One cycle is a period of 4 weeks. You’ll have up to 2 cycles before surgery, and up to 12 cycles after surgery. Your doctor will determine exactly how many cycles you may need based on how you respond to treatment. Read below for more details about how IMFINZI and chemotherapy* are given.

Pre-surgery

Pre Surgery IMFINZI Treatment Cycle Icon
  • You’ll get up to 2 cycles of IMFINZI + chemotherapy.*† The treatment period before surgery is about 8 weeks
  • IMFINZI is given with chemotherapy* at this step to help find and attack cancer cells before surgery. IMFINZI and chemotherapy* may also affect healthy cells

Surgery

  • You’ll pause IMFINZI and chemotherapy* to get surgery that aims to remove most of the cancer. The surgery may remove cancer from parts or all of the stomach or the junction of the stomach and the esophagus
  • Sometimes, surgery does not remove all the cancer cells in these areas. That’s why your doctor will continue to treat you with IMFINZI and chemotherapy* after surgery
