Prevention Clinical Trials for Breast Neoplasm

Clinical trials are research studies that involve people. The clinical trials on this list are for breast neoplasm prevention. All trials on the list are supported by NCI.

NCI’s basic information about clinical trials explains the types and phases of trials and how they are carried out. Clinical trials look at new ways to prevent, detect, or treat disease. You may want to think about taking part in a clinical trial. Talk to your doctor for help in deciding if one is right for you.

  • Metformin Hydrochloride in Preventing Breast Cancer in Patients with Atypical Hyperplasia or In Situ Breast Cancer

    This phase III trial studies how well metformin hydrochloride works compared to placebo in preventing breast cancer in patients with atypical hyperplasia or in situ breast cancer. Chemoprevention is the use of certain drugs to keep cancer from forming. The use of metformin hydrochloride may prevent breast cancer.

  • A Study of Hydroxychloroquine versus Placebo to Prevent COVID-19 Infection in Patients Receiving Radiation Therapy

    This phase II trial studies how well hydroxychloroquine works in preventing infection with the COVID-19 virus in patients receiving radiation therapy. Hydroxychloroquine has been approved for the prevention and treatment of malaria, and the treatment of lupus and rheumatoid arthritis. Receiving radiation therapy may increase the risk of infection with the COVID-19 virus because the patients are in frequent and close contact with healthcare workers and with other patients who may have become infected. Patients receiving treatment for cancer may also have weakened immune system. Giving hydroxychloroquine may help prevent infection with SARS-CoV-2 in patients who are receiving radiation therapy for their cancer.

  • Aerobic Exercise in Changing Biomarkers in Patients with Solid Tumors or Clonal Hematopoiesis

    This trial studies the effect of aerobic exercise in changing biomarkers in patients with solid tumors or clonal hematopoiesis, a condition in which some of the patients' blood cells have a different genetic pattern than the rest of the blood cells. Aerobic exercise stimulates and strengthens the heart and lungs, and improves the body’s use of oxygen. This may help prevent or slow the growth of tumors by changing the biomarkers (signs of disease) found in the blood or by preventing recurrence of certain cancers.

  • 4-hydroxytamoxifen Topical Gel in Reducing the Risk of Breast Cancer in Women with Mammographically Dense Breast

    This randomized phase II trial studies whether putting afimoxifene (4-hydroxytamoxifen topical gel) on the breast skin lowers mammographic density compared with putting placebo gel on the breast skin. Women with dense breast tissue have a higher risk for developing breast cancer. 4-hydroxytamoxifen topical gel applied to the breast skin may allow the drug to get into the breast and lower risk of breast cancer with fewer unwanted effects than oral tamoxifen.

  • Ruxolitinib in Preventing Breast Cancer in Patients with High Risk and Precancerous Breast Lesions

    This phase II trial studies how well ruxolitinib before surgery works in preventing breast cancer in patients with high risk and precancerous breast conditions.

  • Lifestyle Intervention for the Reduction of Breast Cancer Risk in Normal Weight Women

    This trial studies how well a lifestyle intervention works in reducing breast cancer risk through changing body composition and decreasing inflammation in normal weight women. This trial may help researchers learn more about diet and exercise programs designed to decrease body fat in postmenopausal women who are of normal weight but have an elevated risk of breast cancer because of excess body fat.

  • Weight Management and Health Behavior Intervention in Lowering Cancer Risk for BRCA Positive and Lynch Syndrome Families

    This trial studies how well weight management and health behavior intervention works in helping patients with hereditary breast and ovarian cancer and Lynch syndrome mutation carriers lose or maintain a healthy weight and lower their risk for cancer. Lifestyle behaviors such as physical activity, diet, and weight management may play a key role in preventing cancers and improving outcomes even in those with hereditary cancer syndromes.

  • Conjugated Estrogens / Bazedoxifene in Reducing Benign Breast Tissue Proliferation and Menopausal Symptoms in Peri or Post-Menopausal Patients at Moderate Risk for Breast Cancer

    This pilot clinical trial studies how well conjugated estrogens / bazedoxifene works in reducing an increase in non-cancerous breast tissue in patients who are experiencing hot flashes due to perimenopause or menopause and who are at a moderate risk for developing breast cancer. Giving conjugated estrogens / bazedoxifene may reduce breast tissue proliferation while also reducing the amount of hot flashes.

  • Fruit and Vegetable Intervention in Lactating Women to Reduce Breast Cancer Risk

    Mechanistic data show that compounds in fruits and vegetables have anti-inflammatory and anti-carcinogenic properties that can reduce breast cancer risk. However, observational and interventional studies have provided mixed results, and a recent report by the American Institute for Cancer Research (AICR) concludes that the data are insufficient but suggestive that non-starchy vegetables and foods containing carotenoids reduce risk. Measurement error, relatively low levels of carotenoid-rich fruit and vegetable intake in the study populations, emphasis on diet in later adulthood, and confounding factors likely contribute to the weak associations. Therefore, the investigators will conduct a randomized diet intervention trial in young women to assess the extent to which at least 8 to 10 daily servings of deeply pigmented and nutrient dense fruits and vegetables reduces biomarkers of breast cancer risk. The intervention is focused on breastfeeding women because: 1) pregnancy and lactation are normal early life course events; 2) the risk of pregnancy-associated breast cancer (PABC) is increased for up to 10 years postpartum; 3) a dietary intervention to reverse the detrimental molecular changes associated with puberty and pregnancy is more likely to be successful in younger than in older women;4) a diet rich in fruits and vegetables is hypothesized to reduce the inflammation during lactation / weaning and lower PABC risk; 5) postpartum lactating women may be a highly motivated population; and 6) breastmilk provides access to the breast microenvironment and breast epithelial cells to non-invasively assess the diet intervention directly in the breast. Four hundred nursing mothers will be randomly assigned to either the intervention arm, in which they are asked to increase fruit and vegetable intake to at least 8 to 10 daily servings for one year, or to a control condition in which participants receive a dietary guideline for breastfeeding mothers. Women in the intervention arm will receive counseling and boxes of fruits and vegetables for the first 20 weeks, after which they will continue to receive counseling. Changes in DNA methylation and cytokine profiles in breastmilk will be evaluated. Maternal weight and body fat distribution, and infant growth will be monitored. These results will greatly expand our knowledge of how diet alters molecular pathways in a specific organ, ultimately contributing to both breast cancer etiology and prevention.

  • Negative Pressure Wound Therapy in Healing Abdominal Incision in Obese Patients Undergoing Breast Reconstruction Surgery

    This trial studies the safety and how well negative pressure wound therapy works in healing the abdominal incision in obese patients undergoing free flap breast reconstruction surgery. Using negative pressure wound therapy (NPWT) instead of standard dressing (bandages) may improve wound healing at the surgical site in the abdomen where tissue was collected for breast reconstruction surgery.

  • Telephone Genetic Counseling Intervention in Enhancing Genetic Cancer Risk Assessment in Latinas at Risk of Hereditary Breast and Ovarian Cancer

    This phase II trial studies how well a telephone genetic counseling intervention works in enhancing genetic cancer risk assessment in Latinas at risk of hereditary breast and ovarian cancer. Genetic counseling may help providers and patients make decisions for cancer prevention or cancer treatment. Adapting a telephone genetic counseling intervention in Spanish for Latinas who are at risk of hereditary breast and ovarian cancer may enhance their use of genetic counseling services.
