PRT13722 in advanced HR+/HER2- breast cancer
This early study tests PRT13722, by itself and with standard therapies, to see if it is safe and has any signs of activity in adults with HR+/HER2- breast cancer who have progressed on prior treatments.
-
Capivasertib plus endocrine therapy for HR+/HER2- advanced breast cancer after progression on endocrine treatment
This trial will test whether adding capivasertib to standard endocrine therapy helps adults with HR+/HER2- advanced or metastatic breast cancer who progressed on prior endocrine treatment stay on treatment longer and maintain quality of life.

Predicting outcomes for advanced breast cancer patients treated with CDK4/6 inhibitors and endocrine therapy
This study is trying to see how well different CDK4/6 inhibitors combined with hormone therapy work for people with advanced breast cancer and how safe they are.
