Ibrance® ▼ (palbociclib)

What is IBRANCE and what is it used for?

IBRANCE is indicated for the treatment of patients with HR+/HER2- locally advanced or mBC:1

•    In combination with an AI
•    In combination with fulvestrant, following relapse on endocrine therapy

In pre- or peri-menopausal women, endocrine therapy should be combined with an LHRH agonist.

Ibrance is a cancer medicine used to treat locally advanced or metastatic breast cancer (cancer that has begun to spread to other parts of the body). Ibrance can only be used when the cancer cells have receptors for certain hormones on their surface (HR-positive) and do not produce abnormally large quantities of a receptor called HER2 (HER [human epidermal growth factor] negative).2

The active substance in Ibrance, palbociclib, blocks the activity of enzymes known as cyclin-dependent kinases (CDK) 4 and 6, which play a key role in regulating the way cells grow and divide. In some cancers, including HR-positive breast cancer, the activity of CDK 4 and 6 is increased, which helps the cancer cells to multiply uncontrollably. By blocking CDK4 and CDK6, Ibrance slows the growth of HR-positive breast cancer cells.2

The medicine can only be obtained with a prescription.
