Test a BRCA-targeted drug plan for advanced ER-positive breast cancer

Premenopausal HR+/HER2- Metastatic Breast Cancer

Part of Cancer clinical trials.

This Phase 2 study tests how well a treatment plan using palbociclib followed by talazoparib (and possibly atezolizumab) works in certain people with advanced ER-positive breast cancer. It may help by targeting cancer biology linked to BRCA/HRD changes and by strengthening how the cancer is controlled.

Who can take part

  • You have confirmed metastatic (advanced) breast cancer, or stage IV breast cancer that cannot be fully removed with surgery
  • Your tumor is ER-positive and/or progesterone-receptor positive (at least 1% tumor cells stain positive on the latest test)
  • Your breast cancer is HER2-negative/low (HER2 IHC 0, 1+, or 2+ with a negative ISH test)
  • You have a germline BRCA1 or BRCA2 mutation, or many specific “HRD” gene changes (as listed by the study)
  • You’re a woman who is premenopausal (still having periods or meet study blood-test rules while on certain hormone treatments), and you can’t be pregnant
  • Your current health allows treatment (activity level ECOG 0–2, and blood counts/kidney/liver tests meet set thresholds)

NCT04563507Recruiting· Phase 2
Immunotherapy plus hormone therapy for metastatic ER-positive breast cancer

This Phase 2 study tests a combination of immune-based treatments along with hormone (endocrine) therapy to slow or shrink advanced, hormone-receptor positive, HER2-negative breast cancer. You may be a candidate if your cancer has progressed after standard hormone-blocking medicines and you can start treatment with CDK4/6 medicine plus an aromatase inhibitor.

Test blood-based laser scan to guide first-line breast cancer treatment

This Phase 2 study uses a specialized laser test on a blood sample to predict how well palbociclib plus letrozole or anastrozole will work. It’s for certain postmenopausal women with HER2-negative, hormone-receptor positive, advanced (stage IIIb/IV) breast cancer.

New targeted therapy for BRCA/PALB2-mutated HR+ breast cancer

This trial tests a new combination of targeted therapies (saruparib plus camizestrant or hormone therapy) against standard treatments for people with a specific type of advanced breast cancer. It may be a good option if you have a BRCA1, BRCA2, or PALB2 gene mutation and have not yet had treatment for your advanced disease.

Neoadjuvant treatment study for certain breast cancers

This Phase 2 study tests a “precision platform” approach—treatment before surgery—based on specific test results from your breast tumor. It may help determine whether the treatment plan works better for people with particular breast cancer subtypes and healthy organ function.

Study for advanced ER+ HER2− breast cancer after CDK4/6 therapy

This Phase 2 trial tests an investigational “SNF platform” treatment for advanced ER+ (estrogen-receptor positive) and HER2− breast cancer in people who already tried CDK4/6 inhibitor therapy. It may help shrink tumors and improve outcomes for cancers that have come back or spread.

Talazoparib for metastatic breast cancer with BRCA body DNA changes

This Phase 2 trial tests talazoparib, a targeted cancer medicine, in people with metastatic breast cancer that has a harmful BRCA1 or BRCA2 mutation found in tumor DNA circulating in the blood. If you qualify, the goal is to see how well this treatment works when the mutation is detected this specific way.
