A trial looking at different drug combinations for breast cancer

This trial is looking at different combinations of drugs called LEE011, BKM120 and BYL719 alongside the hormone therapy drug fulvestrant. It is for women with breast cancer that has grown into surrounding tissue or spread to another part of the body. Their breast cancer must have receptors for the female hormones oestrogen or progesterone.

If breast cancer has hormone receptors, doctors can treat it with hormone therapy. One type of hormone therapy is fulvestrant. Researchers want to find out if giving other drugs with hormone therapy can improve treatment.
