Comparing the Safety and Effectiveness of a New Hormonal Therapy in Patients with HER2-Negative, ER-Positive Early Breast Cancer

About the Study

This study is comparing safety and effectiveness of a new drug called giredestrant compared to standard hormone therapy in people with early-stage, ER-positive breast cancer. 

This study is no longer enrolling people.

What the Study Involves

This study involves two groups. In addition to the drugs listed in each group, participants will receive a drug to prevent the production of sex hormones. In men, this drug causes the testicles to stop making testosterone. In women, they cause the ovaries to stop making estrogen and progesterone.

Group 1

• Patients will receive Giredestrant orally once a day for five years, or until there is a recurrence of disease or the patient cannot tolerate the drug, whichever comes first.

Group 2

• Patients will receive the hormone therapy of the physician’s choice, either tamoxifen, letrozole, anastrozole, or exemestane, which will be given daily for five years, or until the disease recurs or the patient cannot tolerate the drug, whichever comes first.
