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.

Imlunestrant and Abemaciclib for the Treatment of Estrogen Receptor Positive Breast Cancer in Patients With Minimal Residual Disease, MIRI Trial

This phase II trial studies how well imlunestrant and abemaciclib work in treating patients with estrogen receptor positive (ER+) breast cancer who have tumor remaining in the blood following treatment (minimal residual disease). Estrogen can cause the growth of breast cancer cells. Imlunestrant lowers the amount of estrogen made by the body. This may help stop the growth of tumor cells that need estrogen to grow. Abemaciclib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Imlunestrant and abemaciclib may be effective in treating patients with ER+ breast cancer who have minimal residual disease.

Targeted Therapy Directed by Genetic Testing in Treating Patients With Locally Advanced or Advanced Solid Tumors, The ComboMATCH Screening Trial

This ComboMATCH patient screening trial is the gateway to a coordinated set of clinical trials to study cancer treatment directed by genetic testing. Patients with solid tumors that have spread to nearby tissue or lymph nodes (locally advanced) or have spread to other places in the body (advanced) and have progressed on at least one line of standard systemic therapy or have no standard treatment that has been shown to prolong overall survival may be candidates for these trials. Genetic tests look at the unique genetic material (genes) of patients' tumor cells. Patients with some genetic changes or abnormalities (mutations) may benefit from treatment that targets that particular genetic mutation. ComboMATCH is designed to match patients to a treatment that may work to control their tumor and may help doctors plan better treatment for patients with locally advanced or advanced solid tumors.

Semaglutide and Structured Lifestyle Support to Improve Heart and Blood Vessel Health in Postmenopausal Obese Breast Cancer Survivors Taking Aromatase Inhibitors

This phase IV trial studies whether adding semaglutide to structured lifestyle support improves heart and blood vessel health in postmenopausal obese breast cancer survivors (BCS) who are taking an aromatase inhibitor. In postmenopausal BCS who are taking an aromatase inhibitor, obesity raises the risk of heart and blood vessel problems. Semaglutide is a medicine approved by the United States Food and Drug Administration for weight loss and for lowering the risk of heart events in people with heart disease. The structured lifestyle support in this trial includes counseling on nutrition and physical activity which provides specific recommendations for individuals to follow.

A Navigation Program to Improve Survivorship Support Service Participation Among Non-metastatic Breast Cancer Survivors

This clinical trial studies whether a navigation program improves survivorship support service participation among survivors of breast cancer that has not spread from where it first started (primary site) to other places in the body (non-metastatic). Advances in treatment have caused the number of breast cancer survivors to grow. As this number increases, there are reported unmet supportive care needs in this population, including psychological distress and limitations in physical functioning. To address these needs, many cancer centers offer programming on a variety of topics including psychological services, exercise counseling, and nutrition counseling. Research has shown that while interest in these survivorship programs is high, participation remains low, especially among minority women. Navigation is a healthcare service that is designed to guide a patient through the healthcare system and reduce barriers to timely screening, follow-up, diagnosis, treatment, and supportive care. The navigation program in this trial is specifically focused on helping breast cancer survivors schedule and attend survivorship consultation appointments as well as providing additional support to underserved/vulnerable patients. A navigation program may be effective in improving survivorship support service participation among non-metastatic breast cancer survivors.

Testing the Addition of Anti-Cancer Drug, ZEN003694 (ZEN-3694) and PD-1 Inhibitor (Pembrolizumab), to Standard Chemotherapy (Nab-Paclitaxel) Treatment in Patients With Advanced Triple-Negative Breast Cancer

This phase Ib trial tests the safety and tolerability of ZEN003694 in combination with an immunotherapy drug called pembrolizumab and the usual chemotherapy approach with nab-paclitaxel for the treatment of patients with triple negative-negative breast cancer that has spread to other parts of the body (advanced). Paclitaxel is in a class of medications called antimicrotubule agents. It stops cancer cells from growing and dividing and may kill them. Nab-paclitaxel is an albumin-stabilized nanoparticle formulation of paclitaxel which may have fewer side effects and work better than other forms of paclitaxel. Immunotherapy with monoclonal antibodies, such as pembrolizumab may help the body's immune system attach the cancer and may interfere with the ability of tumor cells to grow and spread. ZEN003694 is an inhibitor of a family of proteins called the bromodomain and extra-terminal (BET). It may prevent the growth of tumor cells that over produce BET protein. Combination therapy with ZEN003694 pembrolizumab immunotherapy and nab-paclitaxel chemotherapy may help shrink or stabilize cancer for longer than chemotherapy alone.

A Blended e-Health Intervention to Improve Fear of Progression in Women With Gynecologic or Breast Cancer

This clinical trial studies whether an intervention supported by technology (blended e-health intervention) works to improve fear of progression (FOP) in women with gynecologic or breast cancer. FOP is the fear patients experience from the possibility that their cancer could grow, spread, or get worse. Managing FOP is a leading unmet concern of cancer patients. High levels of FOP are associated with distress, depression, and increased health care costs, despite this, access to resources to address FOP remain limited. The blended e-health intervention in this trial offers remote group sessions along with online sessions to help patients access the information. Session content incorporates values-based goal setting and skills practices to manage unhelpful beliefs about worry and promote helpful coping behaviors. The sessions may help patients recognize unhelpful thoughts and behaviors which reinforce worry. A blended e-health intervention may be an effective way to improve FOP in women with gynecologic or breast cancer.

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.

Neoadjuvant Breast Cancer Time Restricted Eating

A phase II study to evaluate an innovative approach of following time restricted eating (TRE) in patients with early-stage breast cancer who will start neoadjuvant chemotherapy (NCT) for a new diagnosis of stage I-III breast cancer. Participants at baseline will have a body mass index (BMI) of (25-40) and engage in a TRE 16:8 schedule which includes 16 hours of fasting and 8 hours of eating. Patients will continue TRE for 16 weeks while receiving NCT. For patients who report at the time of the 2-3 week clinic visit that they are finding it challenging to adhere to the 16:8 TRE, instructions will be provided about alternative measures such as changing the time of the day they fast, dietary modifications and finally changing to a 14:10 schedule if other measures fail. For patients requiring NCT for longer than 16 weeks, they will be encouraged to continue TRE. Adherence calculation for the primary endpoint will include data for the first 16 weeks and then monitored separately for any additional optional fasting beyond the first 16 weeks. Adherence to TRE will be self-reported by patients daily through electronic surveys through RedCap and approximately every 2-3 weeks (+/- 5 days) by the research team during their clinic visit.

An Optimized Ultrasound Twinkling Marker for the Imaging of Lymph Nodes in Patients With Clinically Node-Positive Breast Cancer, The UTMOST2 Trial

This phase I trial studies the performance, including ultrasound visibility, of an optimized ultrasound twinkling marker in imaging lymph nodes in patients with clinically node-positive breast cancer. In patients with biopsy-proven breast cancer, biopsy markers are used to identify the sites of cancer involvement in both the breasts and lymph nodes. These biopsy markers are critical for guiding surgical management many months after the marker is placed. For breast radiologists and breast surgeons, there is a need for simple, consistent visibility of biopsy markers by ultrasound, particularly several months after marker placement. Ultrasound is the imaging method of choice, particularly for lymph nodes in the armpit (axilla). Ultrasound is non-ionizing and is more comfortable for patients compared to mammography. However, ultrasound visibility of these markers is challenging and inconsistent, with ultrasound failing to detect the marker approximately 25% of the time. The Mayo-designed investigational biopsy marker takes advantage of an ultrasound phenomenon called twinkling artifact. The Mayo-designed optimized ultrasound twinkling marker may work better than standard biopsy clip marker in imaging lymph nodes in patients with clinically node-positive breast cancer.

Online Nutrition Education to Decrease the Side Effects of Chemotherapy in Patients With Breast Cancer

This trial tests an online nutrition education program focused on decreasing nutrition-related side effects of chemotherapy in patients with breast cancer. Patients undergoing chemotherapy are at risk for complications such as diarrhea or constipation which can lead to poor nutritional intake and malabsorption of nutrients. This study is testing the effects of information delivered via the Cook for Your Life website in conjunction with standard clinical care to improve symptom management during chemotherapy treatment for breast cancer, which could serve as a new model for supportive oncology care.

Prevention of Frailty With Fisetin and Exercise in Breast Cancer Survivors

This phase II trial tests how well fisetin and exercise works in preventing frailty in breast cancer survivors. Fisetin is a natural substance found in strawberries and other foods and is available as a nutritional supplement. Nutritional supplements may be useful in eliminating cells that have undergone a process called senescence. Senescence is when a cell ages and permanently stops dividing but does not die. Over time, large numbers of these cells build up in tissues throughout the body and can release harmful substances that cause inflammation and damage nearby healthy cells. Giving fisetin may eliminate senescent cells in patients with breast cancer undergoing physical activity.

Web-based Lifestyle Program, mHealth and EMA Intervention, to Improve Weight Loss in Rural Stage I-III Postmenopausal Breast and Endometrial Cancer Survivors, HERO-C Trial

This clinical trial identifies the needs and preferences of rural stage I-III postmenopausal breast and endometrial cancer survivors and evaluates the impact of an adaptive, online program, mobile (m)Health + ecological momentary assessment (EMA) intervention, on lifestyle modification and their weight loss efforts. Obesity, a condition marked by an abnormally high, unhealthy amount of body fat, is associated with lower physical and psychological well-being, higher risk of recurrence, and higher cancer-specific and all-cause mortality (number of deaths). Lifestyle factors, such as low physical activity and unhealthy diet, are the main contributors to obesity that are modifiable. Lifestyle weight loss programs focusing on modifiable factors can improve cancer-specific survival and many aspects of health, but access to these programs can be challenging in rural settings. A remote lifestyle program, adapted to individual goals and needs, may help promote healthy behaviors, improve cancer outcomes, and reduce disease burden in stage I-III postmenopausal breast and endometrial cancer survivors.

A Vaccine (STEMVAC) for Improving Survival in Patients With Triple-Negative Breast Cancer and Moderate or Extensive Residual Cancer Burden

This phase II trial evaluates whether a multi-antigen vaccine called STEMVAC improves disease-free survival after surgery in patients with triple-negative breast cancer (TNBC) and moderate or extensive residual cancer burden. TNBC has an aggressive clinical course and poorer disease-free survival compared to other subtypes. While patients who have no remaining tumor in the breast or lymph nodes after surgery have excellent long-term outcomes, patients with moderate or extensive residual cancer burden remain at high risk for early disease return and poorer prognosis. STEMVAC is designed to target proteins that tumor cells use when they become more aggressive and start to spread, and it is believed to work by boosting the immune system to recognize and destroy the invader tumor cells that are causing the disease. Giving STEMVAC after surgery may improve disease-free survival rates in TNBC patients with moderate or extensive residual cancer burden.

Fisetin to Improve Physical Function in Stage I-III Breast Cancer Survivors

This phase II trial tests whether fisetin works to improve physical function in women who have received chemotherapy for stage I-III breast cancer treatment. Fisetin is a naturally occurring substance that is found in strawberries and other foods. Fisetin eliminates cells that have undergone a process called senescence. Senescence is when a cell ages and permanently stops dividing but does not die. Over time, large numbers of these cells build up in tissues throughout the body and can release harmful substances that causes inflammation and damages nearby healthy cells. Studies have shown that chemotherapy causes a build-up of these senescent cells. Giving fisetin may eliminate senescent cells and improve physical function in postmenopausal women who have received chemotherapy for breast cancer.

Phase I Study of Tumor Treating Fields (TTF) in Combination With Cabozantinib or With Pembrolizumab and Nab-Paclitaxel in Patients With Advanced Solid Tumors Involving the Abdomen or Thorax

This phase Ib trial tests the safety, side effects, and best dose of tumor treating fields therapy in combination with either cabozantinib or nab-paclitaxel and atezolizumab in treating patients with solid tumors involving the abdomen or thorax that have spread to other parts of the body (advanced). Tumor treating fields therapy on this study utilizes NovoTTF systems that are wearable devices that use electrical fields at different frequencies that may help stop the growth of tumor cells by interrupting cancer cells' ability to divide. Cabozantinib is in a class of medications called kinase inhibitors. It works by blocking the action of an abnormal protein that signals tumor cells to multiply. This helps slow or stop the spread of tumor cells. Chemotherapy drugs, such as nab-paclitaxel, 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. Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving tumor treating fields therapy in combination with either cabozantinib, or with nab-paclitaxel and atezolizumab may help control advanced solid tumors involving the abdomen or thorax.

Testing the Safety of the Combination of Anti-Cancer Drugs CX-5461 (Pidnarulex) and Trastuzumab Deruxtecan (T-DXd) for Human Epidermal Growth Factor Receptor 2 (HER2)-Positive Solid Tumors and Breast Cancer

This phase I trial tests the safety, side effects, and best dose of pidnarulex in combination with trastuzumab deruxtecan in treating patients with breast cancer and other solid tumors that express varying levels of a protein called HER2 and that has spread from where it first started (primary site) to other places in the body (metastatic), that cannot be removed by surgery (unresectable), or that has spread to nearby tissue or lymph nodes (locally advanced). Pidnarulex is an enzyme inhibitor that causes cell death and prevents tumor cell growth. Trastuzumab deruxtecan is in a class of medications called antibody-drug conjugates. It is composed of a monoclonal antibody, called trastuzumab, linked to a chemotherapy drug, called deruxtecan. Trastuzumab attaches to HER2 positive tumor cells in a targeted way and delivers deruxtecan to kill them. Giving pidnarulex in combination with trastuzumab deruxtecan may be safe, tolerable and/or effective in treating patients with metastatic, unresectable, or locally advanced HER2-expressing breast cancer or other solid tumors.

Evaluation of Alternative Site Goserelin Acetate Injection for Ovarian Function Suppression (OFS) in Local and Locally Advanced Premenopausal Hormone Receptor Positive Breast Cancer Patients

This phase II trial determines if giving goserelin acetate injections in the upper gluteal region is as effective for ovarian function suppression (OFS) as giving injections in the abdomen for ovarian function suppression (OFS) in premenopausal patients with hormone receptor positive breast cancer that has not spread to other parts of the body (localized) or that has spread to nearby tissue or lymph nodes (locally advanced). Goserelin acetate is a drug used to treat prostate cancer, relieve the symptoms of advanced breast cancer, and treat problems with the endometrium (lining of the uterus). Goserelin acetate initially causes the pituitary gland to make more luteinizing hormone (LH) and follicle-stimulating hormone (FSH), temporarily increasing testosterone levels in men and estrogen levels in women. With continued use, goserelin acetate lowers the amount of LH and FSH the pituitary gland releases, leading to a drop in testosterone levels in men and estrogen levels in women. Goserelin acetate may stop the growth of cancer cells that need testosterone or estrogen to grow. It is a type of hormone therapy called a luteinizing hormone-releasing hormone (LHRH) agonist. Giving goserelin acetate injections in the upper gluteal region may be as effective for OFS as giving injections in the abdomen for OFS in premenopausal patients with localized or locally advanced hormone receptor positive breast cancer.

Leuprolide and Goserelin for Ovarian Function Suppression in Pre- or Peri-menopausal Women With Breast Cancer, OFS Trial

This phase II trial compares leuprolide to goserelin for reducing estrogen production by the ovaries in pre- or peri-menopausal women with breast cancer. Estrogen can cause the growth of breast cancer cells. Both leuprolide and goserelin lower the amount of estrogen made by the body. This may help stop the growth of tumor cells that need estrogen to grow. This study compares lower dose leuprolide, higher dose leuprolide, and goserelin for their ability to suppress the function of the ovaries to produce estrogen. Both doses of leuprolide may be as safe, tolerable and/or effective as goserelin in suppressing ovarian function in pre- or peri-menopausal women with breast cancer.

Remotely Delivered, Community-Aligned Weight Loss Interventions Among Breast Cancer Survivors, ¡Vida! Trial

This clinical trial evaluates remotely delivered, community-aligned weight loss interventions in Latina breast cancer survivors. Breast cancer is the second leading cause of cancer death among women in the US. There are population differences in breast cancer mortality, based on specific risk factors, including obesity. Cancer is the leading cause of death among Latinos, and among Latinas, breast cancer is the leading cause of cancer death. An estimated 80% of Latinas in the United States have overweight/obesity, which is associated with poorer breast cancer outcomes. However, few, if any, effective interventions exist to promote and maintain weight loss in Latina breast cancer survivors. The development of an adaptive program that provides survivors with the support they need, as opposed to what is typically available, to improve breast cancer survivorship.

Personalized Exercise Program for Survivors of Breast Cancer, STEPS-BC Trial

This clinical trial studies whether a healthy living intervention (HLI), with or without a physical activity intervention (PAI), helps maintain the ability to exercise, heart health, and quality of life in breast cancer patients who are scheduled to receive chemotherapy treatment. Early detection and enhanced therapies for breast cancer have improved 5-year cancer-related survival rates. Unfortunately, many breast cancer survivors are at high risk for long-term exercise intolerance, decreased heart health, and lower quality of life following chemotherapy. Currently, there are no effective therapies to help patients maintain these areas throughout chemotherapy. The HLI in this study includes virtual health education classes, which provide useful information on topics like proper nutrition, managing stress, and sleep practices. This may help patients understand the importance of living a healthy lifestyle during chemotherapy. The PAI in this study consists of virtual exercise sessions personalized to the needs of the patient, which may make it easier for patients to stay active during chemotherapy. HLI with PAI may be a more effective way to help maintain ability to exercise, heart health, and quality of life in breast cancer patients who are scheduled to receive chemotherapy treatment.
