Hi @poddlejules, I just found out today that my amazing oncologist has managed to swing six free cycles of perjeta for me - $15k worth. I know she was going down a few avenues including the drug company's hardship scheme and my insurance company. I'm being treated privately.
My situation might be a bit unique - can't have AC chemo due to childhood cancer treatment and my cancer is grade 3 node positive - but maybe your friend could ask her treatment team about what additional assistance is available.
Hope this helps.
