ClinConnect Summary

This clinical trial is looking at the safety and effectiveness of a medication called IBRANCE® for women with advanced or metastatic breast cancer. It is a non-interventional study, meaning that researchers will observe how the medication works in real-life situations, without changing how doctors usually treat patients. The trial will include at least 1,000 women over the next nine years to gather important information that can help improve treatment options.

To participate in this study, women must be at least 18 years old and have a confirmed diagnosis of advanced breast cancer that is hormone receptor-positive and HER2-negative. Participants should also be eligible for hormone therapy. Before joining, each participant will sign a consent form to ensure they understand the study. While taking part in the trial, patients can expect regular check-ups to monitor their health and the medication’s effects. It’s important to note that women who are pregnant or have a known allergy to certain medications used in this study cannot participate.
