Open Clinical Trials

The following studies look at treatment for people with metastatic ER-positive breast cancer.  

• Studies for People With ER-Positive, HER2-Negative Advanced or Metastatic Breast Cancer (VERITAC Studies): The VERITAC studies are looking at the safety of an oral study medicine, ARV-471 (also known as vepdegestrant or PF-07850327), and how well it works either alone or combined with another breast cancer medicine, palbociclib (also known as IBRANCE®).
• Treatment Studies for People with ER-Positive, HER2-Negative Advanced or Metastatic Breast Cancer (TACTIVE-U): The TACTIVE-U studies are looking at the safety of an oral study medicine, ARV-471 (also known as vepdegestrant), and how well it works when combined with other breast cancer medicines.
• NCT04673448: Combining the Immunotherapy Dostarlimab and PARP Inhibitor Niraparib for Advanced or Metastatic Breast, Ovarian or Pancreatic Cancer with an Inherited or Tumor BRCA Mutation. This study is looking at the effectiveness of combining the PARP inhibitor, Niraparib and the immunotherapy dostarlimab for treating people with an inherited BRCA mutation (found with genetic testing) or a tumor mutation (found through tumor testing) who have advanced breast, pancreatic or ovarian cancer. 
• NCT05501886: Gedatolisib Plus Fulvestrant With or Without Palbociclib vs Standard-of-Care for the Treatment of Patients With Advanced or Metastatic HR+/HER2- Breast Cancer (VIKTORIA-1).  This study is looking at the efficacy and safety of the selective estrogen receptor degrader (SERD) gedatolisib plus fulvestrant with or without palbociclib for the treatment of patients with locally advanced or metastatic HR+/HER2- breast cancer following progression on or after CDK4/6 and aromatase inhibitor therapy.
• NCT04975308: A Study of Imlunestrant, Investigator's Choice of Endocrine Therapy, and Imlunestrant Plus Abemaciclib in Participants With ER+, HER2- Advanced Breast Cancer (EMBER-3). This study will evaluate the efficacy and safety of the selective estrogen receptor degrader (SERD) imlunestrant, how it works compared to standard hormone therapy, and how well imlunestrant with abemaciclib works compared to imlunestrant in participants with breast cancer that is ER-positive and HER2-negative. 
• NCT05306340: A Study Evaluating the Efficacy and Safety of Giredestrant Plus Everolimus Compared With Exemestane Plus Everolimus in Participants With Estrogen Receptor-Positive, HER2-Negative, Locally Advanced or Metastatic Breast Cancer (evERA Breast Cancer). This study will evaluate the efficacy and safety of the selective estrogen receptor degrader (SERD) giredestrant, plus everolimus compared with exemestane plus everolimus in people with estrogen receptor ER-positive, HER2-negative locally advanced or metastatic breast cancer who have had previous treatment with a CDK4/6 inhibitor and hormone therapy.
• NCT03344965: Olaparib Expanded - Treating Metastatic Breast Cancer in People without gBRCA Mutations. This study will look at whether olaparib is also effective for treating metastatic breast cancer in people who do not have an inherited BRCA mutation. The study is enrolling people with an inherited mutation in PALB2 or an acquired (tumor) mutation in BRCA1 or BRCA2.
• NCT03685331: Olaparib, Palbociclib and Fulvestrant for BRCA-Associated, ER/PR+/HER2-Negative Metastatic Breast Cancer. This study is looking at the side effects and best dose of palbociclib when given with olaparib and fulvestrant for people with HR+/HER2-negative mBC who have a BRCA1 or BRCA2 mutation. 
• NCT04072952: ARV-471 Alone and in Combination With Palbociclib in Patients With ER+/HER2- Locally Advanced or Metastatic Breast Cancer. This is a dose escalation and expansion study to learn the safety and tolerability of ARV-471 alone and combined with palbociclib in people with ER+/HER2- locally advanced or metastatic breast cancer who have received prior hormonal therapy and chemotherapy in the locally advanced/metastatic setting.
• NCT04448886: Sacituzumab Govitecan +/- Pembrolizumab In HR+ / HER2 - MBC. This research study is evaluating the safety and effectiveness of Sacituzumab Govitecan with or without Pembrolizumab in metastatic HR+/HER2- breast cancer.
• NCT04563507: Combined Immunotherapies in Metastatic ER+ Breast Cancer. Patients receiving standard first-line therapy for metastatic HR+ Breast cancer(BC) (letrozole+palbociclib) are randomly assigned to also receive Stereotactic Body Radiation Therapy(SBRT) to each metastatic lesion.
• NCT04895358: Pembrolizumab Plus Chemotherapy Versus Placebo Plus Chemotherapy for HR+/HER2- Inoperable or Metastatic Breast Cancer (KEYNOTE-B49). The study will look at the safety and efficacy of pembrolizumab plus chemotherapy compared to chemotherapy alone in the treatment of HR+/HER2- locally recurrent inoperable or metastatic breast cancer.
