National Cancer Institute "Cancer Moonshot Biobank"

This trial collects multiple tissue and blood samples, along with medical information, from cancer patients. The "Cancer Moonshot Biobank" is a longitudinal study. This means it collects and stores samples and information over time, throughout the course of a patient's cancer treatment. By looking at samples and information collected from the same people over time, researchers hope to better understand how cancer changes over time and over the course of medical treatments.

Adding an Immunotherapy Drug, MEDI4736 (Durvalumab), to the Usual Chemotherapy Treatment (Paclitaxel, Cyclophosphamide, and Doxorubicin) for Stage II-III Breast Cancer

This phase III trial compares the addition of an immunotherapy drug (durvalumab) to usual chemotherapy versus usual chemotherapy alone in treating patients with MammaPrint High 2 Risk (MP2) stage II-III hormone receptor positive, HER2 negative breast cancer. Immunotherapy with monoclonal antibodies, such as durvalumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Chemotherapy drugs, such as paclitaxel, doxorubicin, and cyclophosphamide work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. There is some evidence from previous clinical trials that people who have a MammaPrint High 2 Risk result may be more likely to respond to chemotherapy and immunotherapy. Adding durvalumab to usual chemotherapy may be able to prevent the cancer from returning for patients with MP2 stage II-III hormone receptor positive, HER2 negative breast cancer.

Mobile Health for Adherence in Breast Cancer Patients

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.

Monitoring Symptoms to Help Young Women Take Hormone Therapy for Stage I-III Breast Cancer, ASPEN Study

This phase III trial compares the effect of active symptom monitoring and patient education to patient education alone in helping young women with stage I-III breast cancer stay on their hormone therapy medicines. The patient education tool contains interactive weblinks which provide patients with education material about breast cancer and side effects of therapy. Symptom monitoring is a weblink via email or text message with questions asking about symptoms. Hormone therapy for breast cancer can cause side effects, and may cause some women to stop treatment early. Asking about symptoms more often may help women keep taking hormone therapy medicines.

Acutherapy to Prevent Aromatase Inhibitor-Associated Arthralgias in Non-Hispanic Black Postmenopausal Women With Early-Stage Breast Cancer

This clinical trial evaluates if in-person acupuncture or virtual acupressure therapy prevents aromatase inhibitor-associated joint pain in Non-Hispanic Black postmenopausal women with stage I-III (early-stage) hormone receptor positive (HR+) breast cancer. Aromatase inhibitors (AI) are medications that prevent the formation of the hormone estrogen. They are used in the treatment of postmenopausal women who have hormone-dependent breast cancer. AI therapy prolongs life among patients with early-stage HR+ breast cancer. Many postmenopausal women stop AI therapy early due to debilitating joint pain (arthralgias). Non-Hispanic Black women are more likely to experience side effects and stop their hormonal therapy compared to Non-Hispanic white women. Acupuncture therapy involves inserting thin needles through the skin at specific points on the body to control pain. Acupressure therapy uses the application of pressure or localized massage to specific sites on the body to control symptoms such as pain. Acupuncture and acupressure are types of complementary and alternative medicine. Undergoing in-person acupuncture or participating in virtual acupressure may prevent AI-associated arthralgias (AIAA) in Non-Hispanic Black postmenopausal women with early-stage HR+ breast cancer.

The Sleep After Breast Cancer (ABC) Study - Examining Sleep Changes and Biomarkers Among Breast Cancer Patients

This study is being done to learn more about breast cancer patients' experiences with sleep changes during cancer treatment, identify possible reasons for poor sleep quality, and to find out how stress, social support, and living environment affect sleep.

5-strain Probiotic Formulation in HR-positive Breast Cancer Receiving Aromatase Inhibitor to Prevent Bone Loss

This phase II trial tests how well a probiotic, WBF-038, works in preventing bone loss in patients with early-stage hormone receptor-positive breast cancer who are starting treatment with aromatase inhibitors. Aromatase inhibitors are a drug that blocks the activity of an enzyme called aromatase, which the body uses to make estrogen in the ovaries and other tissues. Blocking aromatase lowers the amount of estrogen made by the body, which may stop the growth of cancer cells that need estrogen to grow. Aromatase inhibitors are used to treat some types of breast cancer or to keep it from coming back. Aromatase inhibitors can affect bone health, weight, blood sugar, and waist size. WBF-038 is a combination of both prebiotics and probiotics, designed to improve metabolic health. Giving WBF-038 may improve bone turnover, bone health, blood sugar, weight, and waist circumference in patients with early-stage hormone receptor-positive breast cancer starting on adjuvant endocrine therapy with an aromatase inhibitor.

Letrozole With and Without Simvastatin for the Treatment of Stage I-III Hormone Receptor Positive, HER2 Negative Breast Cancer

This early phase I trial tests whether letrozole with simvastatin works better than letrozole alone to stop tumor cell proliferation in patients with stage I-III hormone receptor positive, HER2 negative invasive breast cancer. Letrozole and simvastatin may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. The addition of simvastatin to letrozole may be more effective at stopping the growth of cancer cells than letrozole alone.

A Feasibility Trial of a Web Based App Intervention in Hormone Positive Breast Cancer Patients to Improve Adherence to Endocrine Therapy

This clinical trial looks at the use of an internet-based application (app) intervention in improving adherence to endocrine therapy (ET) among patients with early stage hormone receptor-positive HER2-negative breast cancer. ET can significantly reduce the return of the cancer in patients who are compliant with their treatment regimen. Despite this, adherence to ET is poor due to side effects, lack of social support and timely access to clinicians, and poor patient understanding of the necessity and effectiveness of the therapy. An internet-based app may help patients improve their adherence to ET by providing reminders, side effect mitigation strategies available in the educational videos and from contacting providers/ nurse on the research team directly via the app.
