Hello @youngdogmum
In response to your question, should your breast cancer progress to
metastatic (stage 4), you would be eligible for treatment with one of the CDK
4/6 inhibitors as a 'first-line' treatment if the breast cancer was hormone
receptor positive and HER2 negative. The eligibility guidelines do not include
any treatment you may have had for early breast cancer.
As far as cost, the CDKs are on the PBS for first line treatment so you
would pay the cost of a script fee at the pharmacy each time the script
is dispensed. Ribociclib, palbociclib and a third CDK, abemaciclib,
are all listed on the PBS as first line treatment for people newly
diagnosed with metastatic hormone receptor positive, HER2 negative breast
cancer.
Unfortunately none of them is on the PBS for second or later line
treatment. For more information about this, including what BCNA is doing, read
our recent news item on the listing of abemaciclib.
Please feel free to call one of the nurses on our Helpline if we can
help you with anything else – 1800 500 258.
