This is a multicenter, Phase 1b/2 trial. The purpose of phase 1b part of the trial aims to determine the  recommended phase II dose (RP2D) of elacestrant when administered in combination with alpelisib, everolimus, palbociclib, and ribociclib. The Phase 2 part of the trial will evaluate the effectiveness and safety of the various combinations in patients with ER+/HER2- advanced/metastatic breast cancer.

Collection of blood to track serial circulating tumor cells (CTCs) in subjects with metastatic breast cancer (MBC). Study will also collect data from investigators are Mayo Clinic and the Mayo Clinic Health Systems to determine effectiveness of the proposed process.

The purposes of this study are (i) to obtain and study biospecimens from patients with breast cancer that has either spread out of the breast or recurred after initial treatment(s), such as surgery, chemotherapy, and/or radiation, and (ii) to collect information about patients, treatments, and the behavior of the underlying cancer. Research involving biospecimens that are linked to related medical information is one way to learn more about diseases. In this case, we seek to understand the mechanism of tumor spread and determine why people respond differently to specific cancer treatments. In general terms, scientists will study the cells, DNA, RNA, and proteins found in the tumor tissue and/or the blood to understand more about cancer and the body’s response to cancer and related treatments.

The purpose of this study is to measure how well imlunestrant works compared to standard hormone therapy in participants with early breast cancer that is estrogen receptor positive (ER+) and human epidermal receptor 2 negative (HER2-). Participants must have already taken endocrine therapy for two to five years and must have a higher-than-average risk for their cancer to return. 

The purpose of this study is to assess the effectiveness of capivasertib + fulvestrant vs placebo + fulvestrant for the treatment of patients with locally advanced (inoperable) or metastatic HR+/HER2- breast cancer following recurrence or progression on or after Aromatase Inhibitor (AI) therapy.

The purpose of this trial is to assess the safety and effectiveness of the combination of dapagliflozin plus metformin extended release (XR) compared with metformin XR during treatment with alpelisib plus fulvestrant in participants with HR-positive, HER2-negative advanced breast cancer with a PIK3CA mutation following progression on or after endocrine-based therapy.

The objective of this study is to provide preliminary data to support the development of selected technologies for the efficient and reliable analyses of cell free DNA (cfDNA) and circulating tumor cells (CTCs) in the setting of metastatic breast cancer.

The purpose of this study is to identify the recommended Phase 2 dose (RP2D) of LY3484356 administered as monotherapy and in combination with other anticancer therapies in patients with locally advanced or metastatic ER+ breast cancer or ER+ recurrent, persistent, or metastatic endometrial endometrioid cancer (EEC).

The purpose of this study is to evaluate whether or not treatment with alternating 17B-estradiol / anti-estrogen therapies on a defined 8-week / 16-week schedule will more effectively prevent cancer growth than continuous treatment with either type of therapy in patients with metastatic anti-estrogen-resistant ER+ breast cancer.

The purpose of this study is to compare the effectiveness and safety of elacestrant to the standard of care (SoC) options of fulvestrant or an aromatase inhibitor (AI) in women and men with breast cancer whose disease has advanced on at least one endocrine therapy including a CDK4/6 inhibitor in combination with fulvestrant or an aromatase inhibitor (AI) .

The purpose of this study is to assess the antitumor activity of TAS-120 as monotherapy or in combination with Fulvestrant in the treatment of patients with metastatic breast cancer harboring fibroblast growth factor receptor (FGFR) amplifications.

The purpose of this study is to evaluate the safety and performance of the GRAIL MCED test in a population of individuals who are eligible for guideline-recommended cancer screening. In cases with a "cancer signal detected" test result, participants will undergo diagnostic procedures based on the test returned cancer signal origin(s) to determine if they have cancer. The number and types of diagnostic procedures required to achieve diagnostic resolution will be assessed. Participant-reported outcomes will be collected at several time points to assess participants' perceptions about the multi-cancer early detection test.
