Hi @poddlejules
This is Kathy from BCNA's Policy Team. I have seen your questions about paying for Perjeta. Unfortunately Perjeta is only listed on the PBS as a first line treatment - that means only for women newly diagnosed with metastatic breast cancer. If you have already had other treatments for metastatic disease, you are not eligible for Perjeta through the PBS. So you would be paying for it whether you are in the private or public health setting.
As @Dogstar did, you could talk to your medical oncologist about approaching the drug company, Roche, for access to it on compassionate grounds (ie free). They may consider this for you, especially if you have already paid for some treatments with it and it is found to be helping you.
Best wishes
Kathy
