Clinical Trials

The purpose of this study is to explore the clinical utility of routinely measuring thymidine kinase activity (TKa) in HR+ metastatic breast cancer patients receiving treatment with any approved endocrine therapy either alone or in combination with any approved CDK4/6 inhibitor.   

A Phase II study to investigate the potential utility of PD 0332991 in the treatment of early stage ER+ Human epidermal growth factor receptor 2 (HER2)- breast cancer, to investigate whether the combination of PD 0332991 and anastrozole is able to: 1) improve the pathologic complete response rate when compared to the historical control of single agent aromatase inhibitors, 2) result in fewer patients with on therapy Ki67>10% compared to historical control.

The purpose of this study is to determine whether adjuvant chemotherapy (ACT) added to ovarian function suppression (OFS) plus endocrine therapy (ET) is superior to OFS plus ET in improving invasive breast cancer-free survival (IBCFS) among premenopausal, early- stage breast cancer (EBC) patients with estrogen receptor (ER)-positive, HER2-negative tumors and 21-gene recurrence score (RS) between 16-25 (for pN0 patients) and 0-25 (for pN1 patients).

The purpose of this study is to evaluate the PFS of the combination of lasofoxifene and abemaciclib compared to fulvestrant and abemaciclib for the treatment of Pre- and Postmenopausal Women and Men with locally advanced or metastatic ER+/HER2- breast cancer with an ESRl mutation.

The purpose of this study is to determine changes in proliferation (Ki-67) in ER+HER2-breast cancers that receive turkey tail administration.

The purpose of this study is to collect samples of blood and stool and analyse primary tumor from participants with breast cancer or melanoma to see how the bacteria in the body affect cancer and how well it responds to treatment. By comparing samples and data from multiple participants with breast cancer or melanoma, it may be possible to identify how a person's gut health and tumor microenvironment affects how they respond to certain cancer treatments.

The purpose of this study is to determine whether treatment with alpelisib plus fulvestrant will lengthen progression-free survival compared to fulvestrant and a placebo in men and postmenopausal women who have hormone receptor positive (HR+), HER2-negative advanced breast cancer.

This is a peripheral blood Collection Protocol to study the T-cell immune responses of patients with malignancies displaying one of three different patterns of antigen expression: (1) Cohort 1 focuses on cancers displaying a high (80-90%) frequency of MUC1 expression and variably high (unreported to 50%) HER2/neu (“HER2”) expression; (2) Cohort 2 focuses on primary or secondary myelofibrosis (MF) displaying mutated calreticulin (muCALR); (3) Cohort 3 focuses on glioblastoma multiforme (GBM) which often displays the cytomegalovirus tegument protein CMVpp65. Cohort 1 includes blood collections for in vitro studies which are a component of NIH-funded Project 3 within the Mayo Clinic ...
