The purpose of this study is to compare the progression-free survival (PFS) of sacituzumab govitecan with pembrolizumab to that of sacituzumab govitecan alone in patients with PD-L1-negative metastatic TNBC, who have not received prior therapy for metastatic breast cancer and who have not received a prior PD-1/L1 inhibitor.

Subjects can remain on study for as long as they are benefitting from treatment - there are no set number of visits required to participate in this study. Sacituzumab govitecan and pembrolizumab are taken via intravenous (IV) infusion. Risks include decrease in white blood cell count, anemia, nausea, joint pain, and headache.

The U.S. Food and Drug Administration (FDA) has approved Sacituzumab govitecan for metastatic triple-negative breast cancer, however, it is considered experimental in this study because it is currently only approved for patients who have had more treatment than patients eligible to participate in this study. The FDA has approved Pembrolizumab for metastatic triple-negative breast cancer, but it is also considered experimental in this study because it is not currently approved for patients with PD-L1 negative cancer.

This study is for adult patients with Triple Negative Breast Cancer (TNBC) who are at high risk for cardiotoxicity. The purpose of this study is to evaluate a non-anthracycline-based chemotherapy and immunotherapy regimen to determine if this approach reduces heart-related side effects. Participation will include standard of care visits along with questionnaires and blood draws completed for research purposes. Participation in this study is anticipated to last approximately 6 months with follow up over 2 years.

This study is for subjects that are post-menopausal women that have been diagnosed with early-stage, low molecular risk breast cancer. Subjects are expected to remain in the study for 60months. There will be a total of 25 subjects enrolled locally.

The study is designed for patients with Estrogen Receptor (ER) positive, HER2-negative advanced breast cancer resistance to prior adjuvant endocrine treatment. The purpose of the study is to determine the effectiveness of Giredestrant compared with Fulvestrant in combinationof CDK4/6i (Palbociclib, Ribociclib and Abemaciclib). The study drug being utilized is giredestrant. The FDA approved drugs will also be utilized: Zoladex and Lupron (LHRH - Luteinizing hormone-releasing hormone agonists) drugs; as well as, Palbociclib, Ribociclib , Fulvestrant, and Abemaciclib.

The study is for patient that have been diagnosed with ER positive HER2 negative early breast cancer. The main purpose is to determine the efficacy and safety of Elacestrant relative to the standard Endocrine therapy. Subject are expected to be enrolled into the study for 36 months.

The study is for patient that are receiving camizestrant as a treatment. The main purpose of study is to change the dosage of camizestrant from 150mg to 75mg. This change was prompted by updated, emerging data from ongoing studies showing
no difference in efficacy between the 75 mg and 150 mg doses. Subject can expect to be in this study for up to 24 months.

This study is for patients that have been diagnosed with MammaPrint Ultrahigh (MP2) Hormone Receptor (HR) Positive / Human Epidermal Growth Factor Receptor (HER2) Negative Stage II-III breast cancer. The drug being used Durvalumab, Cyclophospharmide, Doxorubicin, and Paclitaxel. The study is being done to compare breast cancer event-free survival between patients randomized to standard of care neoadjuvant chamotherapy alone versus standard of care neoadjuvant chemotherapy concurrent with durvalumab. Patients are expected to be in the study for XXmonths.
