Summary

This trial is testing a new combination therapy for breast cancer.

Who is the study for?
This trial is for postmenopausal women with advanced or metastatic hormone receptor-positive, HER2-negative breast cancer. They must have had disease progression after prior therapy and should not be on certain antiretroviral therapies or have uncontrolled illnesses. Women of childbearing potential are excluded unless they use effective contraception.
What is being tested?
The TAKTIC study tests if Ipatasertib combined with an Aromatase inhibitor or Fulvestrant improves outcomes in breast cancer treatment. It's designed to see how well patients respond to this combination compared to their previous treatments.
What are the potential side effects?
Potential side effects may include gastrointestinal issues, changes in blood sugar levels, fatigue, liver function alterations, and possible heart complications. The severity can vary from mild discomforts to more serious conditions requiring medical attention.
