NCT07407920
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.

Ultra-hypofractionated Whole Breast Irradiation With Lumpectomy Cavity Boost for the Treatment of Stage I-III Breast Cancer
This clinical trial tests how well ultra-hypofractionated (UF) whole breast irradiation (WBI) with lumpectomy cavity boost (CB) works in treating patients with stage I-III breast cancer. Breast conservation therapy (BCT) is the recommended treatment for patients with early stage breast cancer. BCT involves a lumpectomy followed by breast radiation. Radiation therapy uses high energy x-rays, particles, or radioactive seeds to kill tumor cells and shrink tumors. Traditionally, WBI has been given once daily over 5-6 weeks and then those at high-risk for recurrence receive additional radiation (boost) to the lumpectomy cavity daily over 4-8 days. This has now been replaced by moderate hypofractionated radiation. Hypofractionated radiation therapy delivers higher doses of radiation therapy over a shorter period of time and may kill more tumor cells and have fewer side effects. Although moderate hypofractionated radiation therapy reduces the length of treatment from 6-7 weeks to 3-4 weeks, the length of treatment still remains a barrier for many patients. UF-WBI with CB delivers radiation to the whole breast and the surgical cavity at the same time over 5 daily treatments. Giving UF-WBI with CB may prevent recurrence and prolong survival as well as improve the quality of life in patients with stage I-III breast cancer.

Evaluating the Association Among Changes in Gut Microbiome, Fatigue, and Chemotherapy-Induced Nausea in Early Stage Breast Cancer
This pilot study seeks to understand how changes in the bacteria composition (microbiome) of the gut may be associated with the occurrence of fatigue and chemotherapy-induced nausea (CIN) in women undergoing chemotherapy for early stage breast cancer. Patients undergoing chemotherapy may experience fatigue or nausea as a result of their treatment. Known risk factors for fatigue and CIN do not explain the differences in fatigue and CIN occurrence between patients, but changes in the functions of the gut microbiome may be related to the occurrence of fatigue and CIN. This study collects stool samples from breast cancer patients before and after chemotherapy to evaluate how changes in the microbiome may be associated with fatigue and CIN.

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.

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.

Additional Support Program Via Text Messaging and Telephone-Based Counseling for Breast Cancer Patients Receiving Hormonal Therapy
This phase III trial compares an additional support program (text message reminders and/or telephone-based counseling) with usual care in making sure breast cancer patients take their endocrine therapy medication as prescribed (medication adherence). Medication adherence is how well patients take the medication as prescribed by their doctors, and good medical adherence is when patients take medications correctly. Poor medication adherence has been shown to be a serious barrier to effective treatment for hormone receptor positive breast cancer patients. Adding text message reminders and/or telephone-based counseling to usual care may increase the number of days that patients take their endocrine therapy medication as prescribed.

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.

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.

Transcranial Direct Current Stimulation to Improve Gait for Breast Cancer Survivor's Who Received Taxene and/or Platinum Chemotherapy
This clinical trial tests the effect of transcranial direct current stimulation (tDCS) to improve gait in older breast cancer survivors who received taxane and/or platinum chemotherapy. Chemotherapy, especially taxane or platinum therapy, can cause damage to the to the nerves resulting in numbness, tingling and pain, which can cause difficulty walking. It can also cause cognitive dysfunction which may effect gait. TDCS is a non-invasive brain stimulation device which uses a very mild electrical current applied to the scalp to temporarily stimulate a specific area of the brain involved in thinking and movement which may improve walking, particularly while doing two things at once. TDCS may be effective in improving gait for older breast cancer survivors who received taxane and/or platinum chemotherapy.

Identifying Decision Making Needs for Older Adult Women With Stage I-III Breast Cancer Considering Neoadjuvant or Adjuvant Chemotherapy
This study collects information and identifies decision making needs for older adult women with stage I-III breast cancer considering neoadjuvant and adjuvant chemotherapy. Using this information, a decision support tool is then developed to provide patients and physicians with tailored information regarding the risks and benefits of chemotherapy and values clarification to support high-quality, shared decision. Subsequently, the decision support tool will be tested amongst older patients with early-stage breast cancer and health care providers navigating the decision process around chemotherapy, and further refined through an iterative process.

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.

Docetaxel or Paclitaxel in Reducing Chemotherapy-Induced Peripheral Neuropathy in African American Patients With Stage I-III Breast Cancer
This phase II trial studies how well docetaxel or paclitaxel work in reducing chemotherapy-induced peripheral neuropathy in African American patients with stages I-III breast cancer. Drugs used in chemotherapy, such as docetaxel and 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. It is not yet known whether giving docetaxel or paclitaxel may work better than other methods in reducing chemotherapy-induced peripheral neuropathy in patients with breast cancer.

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.

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.

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.
