Read our Breast Neoplasms research guide →Phase 2 — Testing in a bigger group (up to a few hundred people) to see if the treatment actually works and is still safe.
This trial is testing a new medication called for premenopausal women with early-stage breast cancer that is hormone-sensitive. The study has two parts: one compares to an existing treatment called tamoxifen (with some patients also receiving a medicine to suppress ovarian function), and the other looks at how affects the ovaries over a longer period. Researchers want to see if this medication works better than current options for this type of cancer.
Many premenopausal women with hormone-sensitive breast cancer need better treatment options beyond what's currently available. This trial explores whether the new treatment could offer improved outcomes while managing side effects differently than existing therapies.

Depending on which group you're assigned to, you would take a pill by mouth daily for either about 1 month (Cohort 1) or up to 6 months (Cohort 2). Some participants will also receive an injection to suppress ovary function. You'll have regular visits to check how you're tolerating the treatment, provide tumor samples at certain timepoints, and have blood tests and imaging scans. The study will monitor you closely to see how the medication affects your cancer and your body.
