Targeted Therapy Directed by Genetic Testing in Treating Patients With Advanced Refractory Solid Tumors, Lymphomas, or Multiple Myeloma (The MATCH Screening Trial)

This phase II MATCH screening and multi-sub-trial studies how well treatment that is directed by genetic testing works in patients with solid tumors, lymphomas, or multiple myelomas that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced) and does not respond to treatment (refractory). Patients must have progressed following at least one line of standard treatment or for which no agreed upon treatment approach exists. Genetic tests look at the unique genetic material (genes) of patients' tumor cells. Patients with genetic abnormalities (such as mutations, amplifications, or translocations) may benefit more from treatment which targets their tumor's particular genetic abnormality. Identifying these genetic abnormalities first may help doctors plan better treatment for patients with solid tumors, lymphomas, or multiple myeloma.

The Vanguard Study: Testing a New Way to Screen for Cancer

The Vanguard Study is a feasibility study to explore several aspects of evaluating multi-cancer detection (MCD) tests in a future definitive randomized controlled trial. An MCD test measures markers in the blood in order to screen for multiple cancers simultaneously. There is a need to understand how MCDs may work as cancer screening tools. The goal of cancer screening is to reduce the burden of cancer by identifying cancers before they show symptoms or signs, when treatment is likely to be most effective. In this study, adults aged 45-75 without cancer will be randomly assigned to one of 3 groups: 2 separate MCD test groups or a control group. These two MCD tests will not be compared to each other but will be compared to cancers detected in the control group. This study will provide early information on how well MCD tests perform as cancer screening tools. It will also help researchers understand how patients and their doctors make decisions about their care when the MCD test result comes back as normal (negative) or abnormal (positive).

Finding the Best Tamoxifen Dose for Breast Cancer Risk Reduction in Premenopausal Women, RENAISSANCE Trial

This phase II trial evaluates response-guided low-dose tamoxifen for reducing breast density in women who are at higher than average risk for breast cancer. Increasing breast density is a well established risk factor for breast cancer. Tamoxifen is a selective estrogen receptor modulator. It works by blocking the effects of the hormone estrogen in the breast. Tamoxifen has been shown to reduce breast density, even at reduced dosages, and is approved for the prevention of breast cancer.

Acolbifene Versus Low Dose Tamoxifen for the Prevention of Breast Cancer in Premenopausal Women at High Risk for Development of Breast Cancer

This phase IIA trial compares the effect of acolbifene versus low dose tamoxifen in preventing breast cancer in premenopausal women at high risk for developing breast cancer. The usual approach for patients at increased risk for breast cancer is to undergo yearly breast magnetic resonance imaging or ultrasound in addition to yearly mammogram. Premenopausal women at very high lifetime risk for breast cancer (greater than 50%) can consider preventive removal (mastectomy) of both breasts. Premenopausal women age 35 or older with a prior diagnosis of atypical hyperplasia, lobular carcinoma in situ, or an estimated 10-year risk of greater than or equal to 3% or estimated 10-year risk of greater than or equal to 2-5 times that of the average woman (depending on age) may be advised to consider five years of standard dose tamoxifen. Standard dose tamoxifen is four times the dose used in this study. Estrogen can cause the development and growth of breast cancer cells. Acolbifene and tamoxifen blocks the use of estrogen by breast cells. This study may help researchers measure the effects of acolbifene and low dose tamoxifen on markers of breast cancer risk in mammogram imaging, breast tissue, and in blood samples.

Veliparib, Paclitaxel, and Carboplatin in Treating Patients With Solid Tumors That Are Metastatic or Cannot Be Removed by Surgery and Liver or Kidney Dysfunction

This phase I trial studies the side effects and the best dose of veliparib when given together with paclitaxel and carboplatin in treating patients with solid tumors that are metastatic or cannot be removed by surgery and liver or kidney dysfunction. Veliparib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as paclitaxel and carboplatin, 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. Giving veliparib together with paclitaxel and carboplatin may kill more tumor cells.

Low Dose Tamoxifen With or Without Omega-3 Fatty Acids for Breast Cancer Risk Reduction

This phase II trial evaluates tamoxifen, with or without omega-3 fatty acids, for reducing risk of breast cancer among postmenopausal and overweight or obese women who are at increased risk of developing breast cancer. Tamoxifen is a selective estrogen receptor modulator. It works by blocking the effects of the hormone estrogen in the breast. Tamoxifen is approved by the Food and Drug Administration for prevention of breast cancer in women at increased risk. Omega-3 fatty acids have been shown to decrease the amount of fats made in the liver. Omega-3 fatty acids may work to prevent cancer in overweight or obese individuals. Tamoxifen with or without omega-3 fatty acids may be effective at reducing risk of breast cancer among women who are postmenopausal, overweight or obese, and at increased risk.

CIPN Decision Aid for the Improvement of Chemotherapy Decision Making in Patients With Breast Cancer

This clinical trial studies how well a chemotherapy-induced peripheral neuropathy (CIPN) decision aid works in improving chemotherapy decision making among patients with breast cancer. CIPN involves numbness or tingling in the hands or feet and is a debilitating side effect of several commonly used classes of cancer drugs. CIPN symptoms are typically minor at first but can progress with continued treatment to severe symptoms that can affect long-term function, falls risk, and quality of life. Symptoms sometimes resolve after treatment but in patients who experienced CIPN, symptoms are still present 1 year post-treatment in about two-thirds of patients and 3 years post-treatment in approximately half of the patients. Previous studies indicate patients lack awareness of long-term CIPN symptoms. A decision aid that provides information about permanent CIPN, that helps patients understand their treatment priorities, and prepares them for a discussion with their medical oncologist may lead to improvements in treatment decision making, satisfaction with decision making, and ultimately increase patient's achievement of their treatment goals.

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.

A Patient Navigation Intervention for the Improvement of Risk Management Among Women at High Risk of Breast Cancer

This clinical trial studies whether a patient navigation (PN) intervention can be used to improve risk management among women at high risk of breast cancer. Women with a family history of breast cancer have a higher lifetime risk of developing it. Risk management can benefit women at high risk of breast cancer and can include surveillance routines, preventative surgeries, and medications that can dramatically lower the risk of breast cancer and allow early detection. Although risk management can benefit women at high risk of breast cancer, only a small amount actually use it. PN 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 PN intervention in this study is designed to help give women the information and support they need to make choices about their breast cancer risk that they feel good about, which may improve risk management.

An Imaging Technology, Contrast-Enhanced Mammography, in Predicting Breast Cancer

This clinical trial examines a new imaging technology, contrast-enhanced mammography, in predicting breast cancer. Contrast-enhanced mammography is similar to standard mammography, but it includes an intravenous (by vein) injection of iodine-based contrast, which makes tissue and blood vessels more visible in scans. Contrast-enhanced mammography may work better in detecting cancer in the breast that is not seen on other imaging tests and may help doctors find the most suspicious areas of the breast to biopsy, which could increase the chances of finding breast cancer.

Three Fraction Accelerated Partial Breast Irradiation as the Sole Method of Radiation Therapy for Low-risk Stage 0 and I Breast Carcinoma

The investigators proposed approach allows them to deliver a low total dose of radiation to patients with low-risk, early-stage breast cancer which would further minimize the impact of adjuvant therapy. This work has the potential to revolutionize partial breast irradiation by allowing it to take place at many radiation oncology centers with minimal specialized equipment beyond that commonly available. The investigators first step is this proposed single institution phase I/II study designed primarily to evaluate the tolerance of this approach which the investigators are choosing to call Three Fraction APBI (Tri-APBI).

A Synthetic Lethality-Focused Algorithm to Identify Therapeutic Options in Advanced Metastatic Breast Cancer (SYNTHESIS-Breast)

Background: Breast cancer is the most common cancer in US women. There are different types of breast cancers; some are aggressive and difficult to treat. Researchers want to know if an algorithm (ENLIGHT) can help choose approved drugs that will treat these cancers more effectively. Objective: To test whether ENLIGHT can find better treatments for aggressive breast cancers. Eligibility: People aged 18 years and older with triple-negative or endocrine therapy resistant breast cancer; the cancer must have either failed to respond to treatment or come back after treatment. Design: Participants will be screened. A sample of tissue taken from the tumor will be tested using ENLIGHT as well as another method (TruSight Oncology 500). Participants will be assigned to 1 of 3 groups based on the algorithm search results: Group 1: No drug option was recommended. Participants will continue with their standard treatment with their local doctors. Group 2: A drug already approved for the participant's disease was recommended, but the participant has not yet received it. These results will be sent to the participant's local doctors. Participants may return to the NIH if their disease gets worse after using the suggested drugs. Group 3: A drug approved for other uses was recommended. Participants will be treated with the recommended drugs at the NIH; their care will be managed by an NIH doctor. They will continue to receive treatment as long as the drugs are helping them. They will have follow-up visits for 2 years after treatment ends. Participants who are not treated at the NIH will be contacted for a check on their health every 3 months for 2 years.
