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.

Neurotization of the Nipple Areolar Complex to Restore Sensation for Patients With Breast Cancer Undergoing Nipple Sparing Mastectomy and Reconstruction

This phase II trial tests the willingness of patients undergoing nipple sparing mastectomy (NSM) to enroll in a randomized study of NSM with or without neurotization of the nipple areolar complex (NAC). This trial also compares patient reported outcomes, including quality of life and breast and NAC sexual functionality, for patients undergoing NSM with or without neurotization of the NAC. NSM is a standard practice option for patients undergoing preventative mastectomy, but many report dissatisfaction with decreased nipple sensation. Neurotization is a surgical technique using a nerve graft in an attempt to restore NAC sensation. Neurotization during NSM and reconstruction may restore NAC sensation and improve quality of life in breast cancer patients.

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.

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.

ShortStop-HER2: 12 Months vs. 6 Months of HER2-targeted Medications for People With HER2+ Breast Cancer Who Had a Pathologic Complete Response After Chemotherapy Plus Trastuzumab

This phase III trial compares 6 months of human epidermal growth factor receptor 2 (HER2)-targeted therapy to 12 months of HER2-targeted therapy for the treatment of HER2-positive (+) breast cancer in patients that had a pathologic complete response (pCR) after preoperative (neoadjuvant) chemotherapy with trastuzumab. Trastuzumab and pertuzumab are monoclonal antibodies and forms of targeted therapy that attach to a receptor protein called HER2. HER2 is found on some cancer cells. When trastuzumab or pertuzumab attach to HER2, the signals that tell the cells to grow are blocked and the tumor cell may be marked for destruction by the body's immune system. Giving 6 months of HER2-targeted therapy may work better than giving 12 months for the treatment of HER2+ breast cancer in patients that had a pCR after neoadjuvant chemotherapy with trastuzumab.

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.

Breast Cancer, Reasoning, and Activity Intervention

This phase II trial tests whether an exercise intervention works to improve cognitive function in breast cancer survivors. Many breast cancer survivors report cancer-related cognitive impairment, which this has recently become a priority in clinical research due to its dramatic impact on daily functioning, quality of life, and long-term health. Aerobic exercise has the potential to improve cognitive function and brain health in older adults and is recommended as a safe, tolerable, and accessible complementary therapy for breast cancer survivors. This study aims to understand the effects of physical activity compared with health education on memory, attention, and brain health in women with breast cancer. Study findings may help researchers design more programs that can improve memory, attention, and brain health in other women with breast cancer.

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.

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.

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.

Feasibility Study of Biobehavioral Stress Reduction Intervention in Patients With Triple Negative Breast Cancer

This clinical trial aims to see if patients with triple negative breast cancer can complete a biobehavioral stress reduction program that also addresses health related social needs (e.g., utilities, transportation, etc.). The stress reduction program is over ten weeks and includes stress reduction (e.g., progressive muscle relaxation), coping, problem solving, communication, and social support. Health related social needs will be evaluated at the beginning of the study, and referrals will be made to social work to help address those needs. The study will examine stress as reported by the patients and also use biological markers.

Ph2 Study for Optimization of Adjunct Systemic Therapy in HER2+ Patients, MolecularPCR Trial

This phase II trial tests reduced post surgery (adjuvant) therapy for patients with early breast cancer who have confirmed that the disease has responded completely (pathologic complete response) after pre surgical treatment (neoadjuvant) therapy and do not have any tumor genetic material (molecular residual disease) circulating in their blood. Standard of care treatment after surgery consists of 1 year of pembrolizumab for patients with triple negative breast cancer or trastuzumab with or without pertuzumab to complete 1 year of treatment. 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. Pertuzumab and trastuzumab are monoclonal antibodies and forms of targeted therapy that attach to a receptor protein called HER2. HER2 is found on some cancer cells. When pertuzumab or trastuzumab attach to HER2, the signals that tell the cells to grow are blocked and the tumor cell may be marked for destruction by the body's immune system. Lowering the total amount of cancer therapy after breast surgery, may continue to keep the great tumor response to treatment, and may help lower the amount of side effects patients have.

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.

A Physical Activity Program Compared to Health Education for Improving Memory and Attention in Hispanic Women With Newly-Diagnosed Stage I-IIIa Breast Cancer, MAMA Trial

This clinical trial compares a physical activity program to a health education program for improving memory and attention in Hispanic women who are 50 years of age or older and are newly-diagnosed with stage I-IIIa breast cancer. Compared to non-Hispanic White breast cancer survivors (BCS), Hispanic BCS report greater depressive symptoms, emotional distress, anxiety, fear of recurrence, pain, fatigue, and financial toxicity, in addition to more cancer-related psychosocial needs and lower quality of life and social well-being. Cancer-associated cognitive decline (CACD) is a related symptom that has gained increasing attention in clinical research. Based on disparities in other outcomes, it is likely that Hispanic BCS also experience greater CACD than non-Hispanic White BCS, but interventions targeting CACD in Hispanic BCS are non-existent and critically needed. The benefits of aerobic exercise among BCS are well documented and include improvement in health outcomes that are associated with cognitive function including fatigue, anxiety, depression, and sleep. A physical activity program that includes aerobic exercise may be more effective than simple health education for improving cognitive functions like memory and attention in Hispanic women who are 50 years of age or older and are newly-diagnosed with stage I-IIIa breast cancer.

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.

Metformin for the Treatment of Insulin Resistance in Women With Stage I-III Breast Cancer Completing Chemotherapy

This phase III trial evaluates how often women develop insulin resistance and type-2 diabetes and compares metformin with usual care to usual care alone in treating insulin resistance in women with stage I-III breast cancer after chemotherapy. Insulin resistance occurs when cells stop responding to insulin and is a risk factor for developing diabetes and heart disease. Higher levels of insulin have been shown to be associated with aggressive breast cancer. Metformin hydrochloride decreases the amount of glucose (a type of sugar) released into the bloodstream from the liver and increases the body's use of the glucose. Metformin as well as standard of care diet and exercise education is known to lower blood sugar. However, chemotherapy may accelerate metabolic disorders, such as high blood sugar, and the impact of metformin in these breast cancer survivors is not known. Giving metformin with usual care may be more effective than usual care alone in preventing or reversing insulin resistance in women with stage I-III breast cancer after chemotherapy.
