Clinical Trials

This phase III trial studies how well trastuzumab emtansine (T-DM1) and tucatinib work in preventing breast cancer from coming back (relapsing) in patients with high risk, HER2 positive breast cancer. T-DM1 is a monoclonal antibody, called trastuzumab, linked to a chemotherapy drug, called DM1. Trastuzumab is a form of targeted therapy because it attaches to specific molecules (receptors) on the surface of cancer cells, known as HER2 receptors, and delivers DM1 to kill them. Tucatinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving T-DM1 and tucatinib may work better in preventing breast cancer from relapsing in patients with HER2 positive breast cancer compared to T-DM1 alone.

The phase III trial compares the effect of pembrolizumab to observation for the treatment of patients with early-stage triple-negative breast cancer who achieved a pathologic complete response after preoperative chemotherapy in combination with pembrolizumab. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. This trial may help researchers determine if observation will result in the same risk of cancer coming back as pembrolizumab after surgery in triple-negative breast cancer patients who achieve pathologic complete response after preoperative chemotherapy with pembrolizumab.

This phase II trial tests the safety, side effects, and best dose of monosialotetrahexosylganglioside (GM1) and whether it works in reducing or preventing chemotherapy-induced peripheral neuropathy (CIPN) in patients with breast cancer that has spread from where it first started (primary site) to other places in the body (metastatic) who are receiving treatment with paclitaxel. Chemotherapy drugs, such as paclitaxel, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Exposure to chemotherapy drugs like paclitaxel may cause a side effect called CIPN, which is a condition of weakness, numbness, and pain from nerve damage (usually in the hands and feet). GM1 is a part of the body's natural system that insulates nerves and helps to protect nerves from damage. Giving GM1 may help reduce or prevent CIPN in breast cancer patients receiving treatment with paclitaxel.

The purpose of this study is to compare the effects on low risk breast cancer receiving usual care that includes regional radiation therapy, with receiving no regional radiation therapy. Researchers want to see if not giving this type of radiation treatment works as well at preventing breast cancer from coming back.

This study evaluates immunologic response following COVID-19 vaccination in children, adolescents, and young adults with cancer. Vaccines work by stimulating the body's immune cells to respond against a specific disease. The immune response produces protection from that disease. Effects from cancer and from treatments for cancer can reduce the body's natural disease fighting ability (called immunity). Factors such as vaccine type, timing of vaccine dosing related to treatment for cancer and number of vaccine doses or boosts (extra vaccine shots) may strengthen or diminish the body's protective immune response. This study may help researchers learn more about how the body's immune system responds to the COVID-19 vaccine when the vaccination is given during or after cancer treatment.

This phase II trial tests how well an imaging procedure called fludeoxyglucose F-18 (FDG) positron emission tomography/computed tomography (PET/CT) works in predicting response to standard of care chemotherapy prior to surgery in patients with HER2-positive stage IIa-IIIc breast cancer. FDG is a radioactive tracer that is given in a vein before PET/CT imaging and helps to identify areas of active cancer. PET and CT are imaging techniques that make detailed, computerized pictures of areas inside the body. The use of FDG-PET/CT may help doctors better decide if a patient needs more or less treatment before surgery in order to get the best response. This study evaluates whether FDG-PET/CT is useful in predicting a patient's response to standard of care chemotherapy.

This clinical trial compares the use of the connected customized treatment platform (CONCURxP), consisting of using a medication monitoring device called WiseBag along with text message reminders for missed or extra medication events, to enhanced usual care (EUC), where patients only use the Wisebag, to monitor medication adherence in patients with metastatic breast cancer who are taking a CKD4/6 inhibitor. To ensure CDK4/6 inhibitors achieve their full clinical benefit, patients need to take them as prescribed, following a complex treatment schedule. Forgetfulness was the most common reason reported for medication non adherence. Using the WiseBag along with CONCURxP or enhanced usual care may improve medication adherence in patients with metastatic breast cancer who are taking a CKD4/6 inhibitor.

This phase II trial studies how well TPIV100 and sargramostim work in treating patients with HER2 positive, stage II-III breast cancer that has remained after chemotherapy and surgery. It also studies why some HER2 positive breast cancer patients respond better to chemotherapy in combination with trastuzumab and pertuzumab. TPIV100 is a type of vaccine made from HER2 peptide that may help the body build an effective immune response to kill tumor cells that express HER2. Sargramostim increases the number of white blood cells in the body following chemotherapy for certain types of cancer and is used to alert the immune system. It is not yet known if TPIV100 and sargramostim will work better in treating patients with HER2 positive, stage II-III breast cancer.

This Phase III Trial will 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).
