People with HER2+ early breast cancer that has a high likelihood of coming back.
PERJETA is used with Herceptin® (trastuzumab) and chemotherapy after surgery. PERJETA and Herceptin are intravenous (IV) infusions that are given back-to-back in about 1-2.5 hours.*
PHESGO brings together PERJETA and Herceptin in a single injection just under the skin. It is given with chemotherapy. The first dose of PHESGO takes about 8 minutes. After that, receiving PHESGO takes about 5 minutes.*
If you are getting ready to start, or already started, treatment with PERJETA + Herceptin, you may be able to switch to PHESGO if your doctor thinks it’s right for you.
*This does not account for observation time and other aspects of treatment. Actual clinic time may vary.

Both PERJETA and Herceptin are HER2-targeted therapies that work alongside chemotherapy to treat HER2+ breast cancer.
4,804 people with certain types of HER2+ EBC who started treatment after surgery (adjuvant treatment).
To find out if people who took PERJETA + Herceptin + chemotherapy after surgery were less likely to have their cancer come back.
Adjuvant treatment with PERJETA + Herceptin + chemotherapy in 2,400 people lowered the risk of the cancer coming back by 18% when compared to Herceptin in 2,404 people.
Three years after starting the trial, most of the trial participants were still cancer-free, regardless of which treatment they had received. However, slightly more people in the group that had gotten PERJETA + Herceptin + chemotherapy were cancer-free (94.1%), compared with the other group (93.2%).
What are the most serious side effects of PERJETA?
What are other possible serious side effects of PERJETA?
PERJETA should not be used in patients who are allergic to pertuzumab or to any of the ingredients in PERJETA. Possible serious and sometimes fatal side effects of PERJETA include infusion-related reactions and severe allergic reactions (hypersensitivity reactions/anaphylaxis).
See additional Important Safety Information below.
The dosing schedule for PERJETA is organized by cycle. For example, PERJETA is given once every 3 weeks. That is 1 cycle.
You will receive PERJETA + Herceptin for 1 year (up to 18 cycles), unless the side effects become too difficult to manage or the cancer comes back sooner.
PHESGO—a combination with PERJETA and Herceptin in a single ~5 minute injection under the skin.* PHESGO is given as part of a complete treatment regimen for HER2+ breast cancer that includes chemotherapy.
If you’re receiving PERJETA + Herceptin, your doctor may be able to switch you to PHESGO if they think it’s right for you.
*Your first dose is given in ~8 minutes. This does not account for observation time and other aspects of treatment. Actual clinic time may vary.
500 people with certain types of HER2+ early breast cancer.
To find out if there were any differences between PHESGO and PERJETA + Herceptin.
The study measured the amount of medicine in the bloodstream, which is commonly done to check that the injection works like the infusion. The study also looked at how safe the drug was and if it worked on the cancer.
No major difference was seen in the amount of medicine that went into the bloodstream with PHESGO compared to PERJETA + Herceptin.
The combined results of the study showed no major difference is expected in how PHESGO works.
160 people with certain types of HER2+ early breast cancer.
To find out if people preferred one treatment over the other.
All participants were given IV PERJETA + Herceptin + chemotherapy before surgery. After surgery, some were given 3 cycles of IV PERJETA + Herceptin then 3 cycles of PHESGO. Others were given PHESGO first then IV PERJETA + Herceptin. Everyone completed a total of 18 cycles of treatment. Patients were asked which treatment they preferred after they completed 6 cycles.
More people preferred PHESGO over PERJETA + Herceptin
The most common reason people preferred PHESGO was because it took less time in the clinic.
The most common reason people preferred IV PERJETA + Herceptin was because it felt more comfortable during administration.
