  • Multiple Treatment Combinations in Participants With Breast Cancer

    open to eligible females ages 18 years and up

    This is a Phase Ib/II, open-label, multicenter, randomized umbrella study in participants with breast cancer. Cohort 1 will focus on participants with inoperable, locally advanced or metastatic, estrogen receptor (ER)-positive, HER2-negative breast cancer who had disease progression during or following treatment with a cyclin-dependent kinase 4/6 inhibitor (CDK4/6i; e.g., palbociclib, ribociclib, abemaciclib) in the first- or second-line setting. Cohort 2 will focus on inoperable, locally advanced or metastatic, ER-positive, HER2-positive breast cancer with previous progression to standard-of-care anti-HER2 therapies, of which one was a trastuzumab-and-taxane-based systemic therapy (including in the early setting if recurrence occurred within 6 months of finishing adjuvant therapy) and one was a HER2-targeting antibody-drug conjugate (ADC; e.g., ado-trastuzumab emtansine or trastuzumab-deruxtecan) or a HER2-targeting tyrosine kinase inhibitor (TKI; e.g., tucatinib, lapatinib, pyrotinib or neratinib). The study is designed with the flexibility to open new treatment arms as new treatments become available, close existing treatment arms that demonstrate minimal clinical activity or unacceptable toxicity, or modify the patient population. During Stage 1, participants in each cohort will be randomly assigned to treatment arms. Participants in the control or experimental arms who experience unacceptable toxicity, disease progression as determined by the investigator according to RECIST v1.1, or loss of clinical benefit as determined by the investigator during Stage 1 will be given the option of receiving a different treatment combination during Stage 2, provided they meet eligibility criteria and a treatment arm is open for enrollment. No Stage 2 treatment is currently available.

  • Avelumab With Binimetinib, Sacituzumab Govitecan, or Liposomal Doxorubicin in Treating Stage IV or Unresectable, Recurrent Triple Negative Breast Cancer

    open to eligible people ages 18 years and up

    This phase II trial studies how well the combination of avelumab with liposomal doxorubicin with or without binimetinib, or the combination of avelumab with sacituzumab govitecan works in treating patients with triple negative breast cancer that is stage IV or is not able to be removed by surgery (unresectable) and has come back (recurrent). Immunotherapy with checkpoint inhibitors like avelumab require activation of the patient's immune system. This trial includes a two week induction or lead-in of medications that can stimulate the immune system. It is our hope that this induction will improve the response to immunotherapy with avelumab. One treatment, sacituzumab Govitecan, is a monoclonal antibody called sacituzumab linked to a chemotherapy drug called SN-38. Sacituzumab govitecan is a form of targeted therapy because it attaches to specific molecules (receptors) on the surface of tumor cells, known as Tumor-associated calcium signal transducer 2 (TROP2) receptors, and delivers SN-38 to kill them. Another treatment, liposomal doxorubicin, is a form of the anticancer drug doxorubicin that is contained in very tiny, fat-like particles. It may have fewer side effects and work better than doxorubicin, and may enhance factors associated with immune response. The third medication is called binimetinib, which may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth, and may help activate the immune system. It is not yet known whether giving avelumab in combination with liposomal doxorubicin with or without binimetinib, or the combination of avelumab with sacituzumab govitecan will work better in treating patients with triple negative breast cancer.

  • CompassHER2-pCR: Decreasing Chemotherapy for Breast Cancer Patients After Pre-surgery Chemo and Targeted Therapy

    open to eligible people ages 18 years and up

    This trial studies how well paclitaxel, trastuzumab, and pertuzumab work in eliminating further chemotherapy after surgery in patients with HER2-positive stage II-IIIa breast cancer who have no cancer remaining at surgery (either in the breast or underarm lymph nodes) after pre-operative chemotherapy and HER2-targeted therapy. Drugs used in chemotherapy, such as 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. Trastuzumab and pertuzumab are both a form of "targeted therapy" because they work by attaching themselves to specific molecules (receptors) on the surface of tumor cells, known as HER2 receptors. When these drugs attach to HER2 receptors, 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 paclitaxel, trastuzumab, and pertuzumab may enable fewer chemotherapy drugs to be given without compromising patient outcomes compared to the usual treatment.

  • DCIS: RECAST Trial Ductal Carcinoma In Situ: Re-Evaluating Conditions for Active Surveillance Suitability as Treatment

    open to eligible females ages 18 years and up

    The goal of this trial is to see if active surveillance monitoring and hormonal therapy in patients diagnosed with ductal cell carcinoma in situ (DCIS), an early stage of breast cancer, can be an effective management of the disease. Participants will be asked to receive control hormonal therapy or an investigational hormonal therapy treatment. Participants will be asked to return for evaluation with MRI at three months and six months. Depending on the evaluation participants will have the option to continue on the treatment. If the evaluation suggests surgery is recommended, the participant will discontinue the study treatment and will undergo surgery. In addition to the treatment and MRI evaluation, participants will be asked to provide blood sample to understand their immune status, provide saliva sample for genetic testing, provide the study with a portion of the tissue or slides generated from tissue removed during surgery performed as part of their standard of care.

  • Topical Tranexamic Acid in Breast Reconstruction

    open to eligible females ages 18 years and up

    Improvement in bleeding and bruising has been described by using both intravenous and topical off-label applications of Tranexamic Acid (TXA) in many surgical fields. This trial tests how well applying tranexamic acid (TXA) to the surface of the surgical site (topically) works to reduce post-operative bleeding (hematomas) and fluid collections (seromas) in women undergoing surgery to remove both breasts (bilateral mastectomy) immediately followed by surgery to rebuild the breast (reconstruction). The formation of hematomas and seromas, a common post-mastectomy complication, can interfere with breast reconstruction and increase the risk of infection and wound healing and can potentially delay cancer treatments. TXA is a synthetic molecule that pushes the body's clotting cascade toward clot formation to improve blood clotting. Applying TXA topically to the surgical site before closing the incision may prevent hematoma and seroma formation in post-mastectomy breast reconstruction patients. Participants will be recruited from patients undergoing bilateral mastectomy at University of California, San Francisco.

  • Improving Nutrition and Physical Activity for Cancer Survivors (Tools To Be Fit)

    open to eligible people ages 18 years and up

    This clinical trial studies the effect of four different intervention components "tools" on body weight, nutrition, and physical activity in cancer survivors. Studies indicate that people with a history of cancer whose nutrition and physical activity habits are consistent with the American Cancer Society's Nutrition and Physical Activity Guidelines may have longer disease-free survival. The four different intervention components may help patients with a history of cancer adopt recommended health behaviors after they have completed treatment.

  • Microbiome and Association With Implant Infections

    open to eligible females ages 18 years and up

    The most common tissue expander-related infections are from Staphylococcus and Pseudomonas species. In addition, from breast tissue microbiome studies, Staphylococcus and Pseudomonas show variable abundance across samples. The investigator hypothesizes that participants undergoing mastectomy with high initial abundance of Staphylococcus and/or Pseudomonas are more likely to develop subsequent tissue expander-related infections from these respective organisms.

  • Pembrolizumab vs. Observation in People With Triple-negative Breast Cancer Who Had a Pathologic Complete Response After Chemotherapy Plus Pembrolizumab

    open to eligible people ages 18 years and up

    The phase III trial compares the effect of pembrolizumab to observation for the treatment of patients with early-stage triple-negative breast cancer who achieved a pathologic complete response after preoperative chemotherapy in combination with pembrolizumab. 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. This trial may help researchers determine if observation will result in the same risk of cancer coming back as pembrolizumab after surgery in triple-negative breast cancer patients who achieve pathologic complete response after preoperative chemotherapy with pembrolizumab.

  • Pembrolizumab With Carboplatin Compared to Carboplatin Alone in Breast Cancer Patients With Chest Wall Disease

    open to eligible people ages 18 years and up

    This is a phase II multicenter study including breast cancer patients with chest wall disease that is hormone resistant (estrogen receptor (ER) positive/progesterone receptor (PR) positive/human epidermal growth factor receptor 2 (HER2) negative breast cancer with progressive disease on 2 prior lines of hormonal therapy) or triple negative (ER negative/PR negative/HER2 negative, TNBC). Eighty-four patients will be enrolled at Translational Breast Cancer Research Consortium (TBCRC) sites and will be randomized 2:1 to receive treatment with pembrolizumab and carboplatin (n=56, Arm A) or carboplatin alone (n=28, Arm B) until documented disease progression. Patients randomized to Arm B may cross-over following progression to pembrolizumab with or without carboplatin at investigator's discretion (Arm Bx). Patients may have received any number of prior lines of chemotherapy. Patients in Arm A will be treated with pembrolizumab 200 mg IV and carboplatin area under curve (AUC) 5 IV every 3 weeks for at least 6 cycles followed by maintenance pembrolizumab 200 mg IV every 3 weeks if stable or responding disease. Patients in Arm B will be treated with carboplatin AUC 5 IV every 3 weeks until progression, whereupon they may cross-over to pembrolizumab 200 mg IV every 3 weeks with or without carboplatin at investigator's discretion (Arm Bx). An interim analysis for futility will be performed after 18 patients are enrolled into Arm B to allow early stopping of that trial arm for lack of efficacy. The primary endpoint is to compare disease control rates at 18 weeks of treatment. Secondary endpoints include progression free survival, toxicity, and overall response rate.

  • Denosumab on Preventing Breast Cancer in Women With a BRCA1 Germline Mutation

    open to eligible females ages 25-55

    This phase III trial compares denosumab to placebo for the prevention of breast cancer in women with a BRCA1 germline mutation. A germline mutation is an inherited gene change which, in the BRCA1 gene, is associated with an increased risk of breast and other cancers. Denosumab is a monoclonal antibody that is used to treat bone loss in order to reduce the risk of bone fractures in healthy people, and to reduce new bone growths in cancer patients whose cancer has spread to their bones. Research has shown that denosumab may also reduce the risk of developing breast cancer in women carrying a BRCA1 germline mutation.

  • T-DM1 and Tucatinib Compared With T-DM1 Alone in Preventing Relapses in People With High Risk HER2-Positive Breast Cancer, the CompassHER2 RD Trial

    open to eligible people ages 18 years and up

    This phase III trial studies how well trastuzumab emtansine (T-DM1) and tucatinib work in preventing breast cancer from coming back (relapsing) in patients with high risk, HER2 positive breast cancer. T-DM1 is a monoclonal antibody, called trastuzumab, linked to a chemotherapy drug, called DM1. Trastuzumab is a form of targeted therapy because it attaches to specific molecules (receptors) on the surface of cancer cells, known as HER2 receptors, and delivers DM1 to kill them. Tucatinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving T-DM1 and tucatinib may work better in preventing breast cancer from relapsing in patients with HER2 positive breast cancer compared to T-DM1 alone.

  • TACTIVE-U: A Study to Learn About the Study Medicine (Vepdegestrant) When Given With Other Medicines in People With Advanced or Metastatic Breast Cancer (Sub-Study A)

    open to eligible people ages 18 years and up

    The purpose of this clinical trial is to learn about the safety and effects of the study medicine (called ARV-471) when given together with other medicines for the potential treatment of advanced or metastatic breast cancer. This study is seeking participants who have breast cancer that: - is advanced, may have spread to other organs (metastatic) and cannot be fully treated by surgery or radiation therapy - is sensitive to hormonal therapy (it is called estrogen receptor positive); and - is no longer responding to previous treatments This study is divided into separate sub-studies. For Sub-Study A: All participants will receive ARV-471 and a medicine called abemaciclib. ARV-471 will be given by mouth, at home, 1 time a day. Abemaciclib will be given by mouth, at home, 2 times a day. We will examine the experiences of people receiving the study medicines. This will help us determine if the study medicines are safe and effective. Participants will continue to take ARV-471 and abemaciclib until their cancer is no longer responding, or side effects become too severe. They will have visits at the study clinic about every 4 weeks.

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

    open to all eligible people

    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.

  • Women Informed to Screen Depending on Measures of Risk (Wisdom Study)

    open to eligible females ages 30-74

    Most physicians still use a one-size-fits-all approach to breast screening in which all women, regardless of their personal history, family history or genetics (except BRCA carriers) are recommended to have annual mammograms starting at age 40. Mammograms benefit women by detecting cancers early when they are easier to treat, but they are not perfect. Recent news stories have discussed some of the potential harms: large numbers of positive results that cause stressful recalls for additional mammograms and biopsies. With the current screening approach, half of the women who undergo annual screening for ten years will have at least one false positive biopsy. Potentially more important are cancer diagnoses for growths that might never come to clinical attention if left alone (called "overdiagnosis"). This can lead to unnecessary treatment. Even more concerning is evidence that up to 20% of breast cancers detected today may fall into the category of "overdiagnosis." This study compares annual screening with a risk-based breast cancer screening schedule, based upon each woman's personal risk of breast cancer. The investigators have designed the study to be inclusive of all, so that even women who might be nervous about being randomly assigned to receive a particular type of care (a procedure that is typical in clinical studies) will still be able to participate by choosing the type of care they receive. For participants in the risk-based screening arm, each woman will receive a personal risk assessment that includes her family and medical history, breast density measurement and tests for genes (mutations and variations) linked to the development of breast cancer. Women who have the highest personal risk of developing breast cancer will receive more frequent screening, while women with a lower personal risk would receive less frequent screening. No woman will be screened less than is recommended by the USPSTF breast cancer screening guidelines. If this study is successful, women will gain a realistic understanding of their personal risk of breast cancer as well as strategies to reduce their risk, and fewer women will suffer from the anxiety of false positive mammograms and unnecessary biopsies. The investigators believe this study has the potential to transform breast cancer screening in America.

  • Additional Support Program Via Text Messaging and Telephone-Based Counseling for Breast Cancer Patients Receiving Hormonal Therapy

    Sorry, currently not accepting new patients, but might later

    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.

  • TC-510 In Patients With Advanced Mesothelin-Expressing Cancer

    Sorry, in progress, not accepting new patients

    TC-510 is a novel cell therapy that consists of autologous genetically engineered T cells expressing two synthetic constructs: first, a single-domain antibody that recognizes human Mesothelin, fused to the CD3-epsilon subunit which, upon expression, is incorporated into the endogenous T cell receptor (TCR) complex and second, a PD-1:CD28 switch receptor, which is expressed on the surface of the T cell, independently from the TCR. The PD-1:CD28 switch receptor comprises the PD-1 extracellular domain fused to the CD28 intracellular domain via a transmembrane domain. Thus, the switch is designed to produce a costimulatory signal upon engagement with PD-L1 on cancer cells.

    Sorry, in progress, not accepting new patients

    This randomized phase III trial studies doxorubicin hydrochloride, cyclophosphamide, and paclitaxel to see how well they work with or without bevacizumab in treating patients with cancer that has spread to the lymph nodes (lymph node-positive) or cancer that has not spread to the lymph nodes but is at high risk for returning (high-risk, lymph node-negative breast cancer). Drugs used in chemotherapy, such as doxorubicin hydrochloride, cyclophosphamide, 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. Monoclonal antibodies, such as bevacizumab, may interfere with the ability of tumor cells to grow and spread. Bevacizumab may also stop the growth of breast cancer by blocking blood flow to the tumor. Giving chemotherapy after surgery may kill any tumor cells that remain after surgery and help prevent the tumor from returning. It is not yet known whether doxorubicin hydrochloride, cyclophosphamide, and paclitaxel are more effective with or without bevacizumab.

  • Endocrine Response in Women With Invasive Lobular Breast Cancer

    Sorry, in progress, not accepting new patients

    RATIONALE: Currently, adjuvant endocrine therapy often follows a "one-size-fits- all" approach, with most premenopausal women receiving tamoxifen, and most postmenopausal receiving aromatase inhibitor therapy. In current clinical practice, patients with invasive lobular carcinoma are treated no differently than patients with invasive ductal carcinoma based on the void of information specific to patients with this tumor type. Identification of a biological signal of tamoxifen and/or AI-resistance and/or fulvestrant-sensitivity in ILC patients would have dramatic implications for the future management of this breast cancer subtype. PURPOSE: To study whether fulvestrant is more effective than anastrozole or tamoxifen in reducing Ki67 in ILC and whether that Ki67 reduction will correlate with alterations in expression of ER and ER-regulated genes. Differential Ki67 effect in this study will serve as a surrogate for outcome of ILC patients on endocrine therapy. Primary Objective: To determine the change from baseline to post-treatment Ki67 values in ER-positive, HER2-negative ILC tissue derived from postmenopausal women awaiting definitive surgery or further neoadjuvant treatment who are randomized to 21-24 days of neoadjuvant endocrine treatments with fulvestrant (two 250 mg IM injections given on day 1), anastrozole (1mg given orally daily), or tamoxifen (20mg given orally daily).

  • Estradiol in Treating Patients With ER Beta Positive, Triple Negative Locally Advanced or Metastatic Breast Cancer

    Sorry, accepting new patients by invitation only

    This phase II trial studies how well estradiol works in treating patients with estrogen receptor beta (ER beta) positive, triple negative breast cancer that has spread to nearby tissue or lymph nodes (locally advanced) or other places in the body (metastatic). Hormone receptors like ER beta allow the body to respond appropriately to hormones. Triple negative means that the breast cancer does not express other hormone receptors called ER alpha, progesterone, and HER2. In some people with triple negative breast cancer, ER beta is overexpressed. Tumor cells that overexpress ER beta grow slower in the laboratory and this growth is slowed in the presence of estrogen. Estradiol is a form of estrogen. This study may help doctors determine whether tumor cells that overexpress ER beta shrink in the presence of estradiol.

  • Hormone Therapy With or Without Combination Chemotherapy in Treating Women Who Have Undergone Surgery for Node-Negative Breast Cancer (The TAILORx Trial)

    Sorry, in progress, not accepting new patients

    This randomized phase III trial studies the best individual therapy for women who have node-negative, estrogen-receptor positive breast cancer by using a special test (Oncotype DX), and whether hormone therapy alone or hormone therapy together with combination chemotherapy is better for women who have an Oncotype DX recurrence score of 11-25. Estrogen can cause the growth of breast cancer cells. Hormone therapy may fight breast cancer by blocking the use of estrogen by the tumor cells or by lowering the amount of estrogen the body makes. Drugs used in chemotherapy 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 hormone therapy together with more than one chemotherapy drug (combination chemotherapy) has been shown to reduce the chance of breast cancer recurrence, but the benefit of adding chemotherapy to hormone therapy for women with node-negative, estrogen-receptor positive breast cancer is small. New tests may provide information about which patients are more likely to benefit from chemotherapy.

  • Olaparib In Metastatic Breast Cancer

    Sorry, in progress, not accepting new patients

    This research study is for patients with metastatic breast cancer. - Metastatic means that the cancer has spread beyond the breast. In addition, through genetic testing of the blood or tumor, an altered gene has been found that suggests the tumor may not be able to repair its genetic material (DNA) when it becomes damaged. - This aspect of the cancer may cause it to be more sensitive - that is, more effectively killed by certain types of drugs such as the study agent being evaluated in this trial, Olaparib. - Olaparib is a type of drug known as a PARP inhibitor. Some types of breast cancer and ovarian cancer share some basic features that make them sensitive to similar treatments. Information from those other research studies suggests that this drug may help to treat metastatic breast cancer. - This study will evaluate whether olaparib is effective in breast cancer patients whose tumor has a mutation in one of the other genes that function with BRCA1 and BRCA2 to repair damaged DNA .This mutation may have been inherited from a parent, or may have developed only in the tumor. - This study will also evaluate whether olaparib is effective in breast cancer patients whose tumor has a mutation in BRCA1 or BRCA2 that was acquired by the tumor, but not inherited.

  • Paclitaxel and Trastuzumab With or Without Lapatinib in Treating Patients With Stage II or Stage III Breast Cancer That Can Be Removed by Surgery

    Sorry, in progress, not accepting new patients

    This randomized phase III trial studies paclitaxel and trastuzumab with or without lapatinib to see how well they work in treating patients with stage II or stage III breast cancer that can be removed by surgery. Drugs used in chemotherapy, such as 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. Monoclonal antibodies, such as trastuzumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Lapatinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving paclitaxel with trastuzumab and/or lapatinib before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. It is not yet known which regimen is more effective in treating patients with breast cancer.

  • T-DM1 vs Paclitaxel/Trastuzumab for Breast (ATEMPT Trial)

    Sorry, in progress, not accepting new patients

    This research study is a Phase II clinical trial. Phase II clinical trials test the effectiveness of an investigational drug to learn whether the drug works in treating a specific cancer. "Investigational" means that the drug is still being studied and that research doctors are trying to find out more about it-such as the safest dose to use, the side effects it may cause, and if the drug is effective for treating different types of cancer. It also means that the FDA has not approved this drug for use patients undergoing adjuvant treatment for HER2+ breast cancer. Trastuzumab emtansine (T-DM1) is a drug that may stop cancer cells from growing. This drug has been used in other research studies and information from those other research studies suggests that this drug may help to prevent the recurrence of breast cancer in this research study. The use of T-DM1 in this research study is experimental, which means it is not approved by any regulatory authority for the adjuvant treatment of HER2-positive breast cancer. However, it FDA-approved for metastatic HER2-positive breast cancer. T-DM1 has caused cancer cells to die in laboratory studies. In preclinical studies, this drug has prevented or slowed the growth of breast cancer. The breast cancer treatments (paclitaxel and Trastuzumab) used in this study are considered part of standard-of-care regimens in early breast cancer. A standard treatment means that this is a treatment that would be accepted by the majority of the medical community as a suitable treatment for your type of breast cancer. In this research study, the investigators are looking to see if the study drug T-DM1 will have less side effects than traditional HER2-positive breast cancer treatment of trastuzumab and paclitaxel. The investigators are also hoping to learn about the long term benefits and disease-free survival of participants who take the study drug T-DM1 in comparison to those participants to take the combination of trastuzumab and paclitaxel.

  • T-VEC With Chemotherapy or Endocrine Therapy in Treating Participants With HER2- Negative Breast Cancer

    Sorry, in progress, not accepting new patients

    This phase Ib trials studies the side effects and how well talimogene laherparepvec works when given together with chemotherapy or endocrine therapy in treating patients with breast cancer that does not express the human epidermal growth factor receptor 2 (HER2) protein and has spread to other places in the body (metastatic), cannot be removed by surgery (unresectable), or has come back (recurrent). Biological therapies, such as talimogene laherparepvec, use substances made from living organisms that may attack specific tumor cells and stop them from growing or kill them. Chemotherapy drugs, such as nab-paclitaxel, gemcitabine, 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. Estrogen can cause the growth of breast cancer cells. Drugs used as endocrine therapy, such as letrozole, anastrozole, exemestane, tamoxifen or fulvestrant, may lessen the amount of estrogen made by the body or may may stop the growth of tumor cells by blocking estrogen from connecting to the cancer cells. Giving talimogene laherparepvec with chemotherapy or endocrine therapy may work better in treating patients with HER2-negative breast cancer.

  • Tamoxifen Citrate or Letrozole With or Without Bevacizumab in Treating Women With Stage IIIB or Stage IV Breast Cancer

    Sorry, in progress, not accepting new patients

    This randomized phase III trial studies tamoxifen citrate or letrozole together with bevacizumab to see how well it works compared with tamoxifen citrate or letrozole alone in treating women with stage IIIB or stage IV breast cancer. Estrogen can cause the growth of breast cancer cells. Hormone therapy using tamoxifen citrate or letrozole may fight breast cancer by blocking the use of estrogen by the tumor cells. Immunotherapy with monoclonal antibodies, such as bevacizumab, may induce changes in the body's immune system and may interfere with the ability of tumor cells to grow and spread. It is not yet known whether giving hormone therapy is more effective with or without bevacizumab in treating advanced breast cancer.

  • Testing Olaparib Either Alone or in Combination With Atezolizumab in BRCA Mutant Non-HER2-positive Breast Cancer

    Sorry, in progress, not accepting new patients

    This randomized phase II trial studies how well olaparib with or without atezolizumab work in treating patients with non-HER2-positive breast cancer that has spread to nearby tissue or lymph nodes (locally advanced), that cannot be removed by surgery (unresectable), or that has spread from where it first started (primary site) to other places in the body (metastatic). Olaparib is an inhibitor of PARP, an enzyme that helps repair deoxyribonucleic acid (DNA) when it becomes damaged. Blocking PARP may help keep cancer cells from repairing their damaged DNA, causing them to die. PARP inhibitors are a type of targeted therapy. Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the body's immune system attack the tumor, and may interfere with the ability of tumor cells to grow and spread. It is not known whether giving olaparib with or without atezolizumab will work better in patients with non-HER2-positive breast cancer.

  • Active After Cancer Trial (AACT)

    Sorry, in progress, not accepting new patients

    This study is being done to determine whether a telephone-based counseling intervention can help survivors of breast and colorectal cancer increase their weekly physical activity. Observational evidence suggests that physical activity after breast and colorectal cancer diagnosis decreases recurrence rates. Unfortunately, many people become less active during cancer therapy, and a substantial proportion never return to pre-diagnosis levels of physical activity. This study looks to see if people who have recently finished chemotherapy for breast, colon or rectal cancer can be motivated to increase their exercise by talking to an exercise specialist over the phone. The study also looks at changes in mood, fatigue, fitness, fat distribution and weight.

  • Provide at Home Subcutaneous Administration of Pertuzumab and Trastuzumab Fixed-Dose Combination (PH FDC SC) for Patients With HER2-Positive Breast Cancer During the COVID-19 Pandemic

    Sorry, not accepting new patients

    This single arm, multicenter study provides the pertuzumab and trastuzumab fixed-dose combination formulation for subcutaneous injection (PH FDC SC) administered at home by a home health nursing provider for patients with human epidermal growth factor receptor 2-positive (HER2+) breast cancer who have completed concurrent chemotherapy with pertuzumab (Perjeta) and trastuzumab (Herceptin) by intravenous administration (P+H IV) and are currently receiving or will be receiving maintenance therapy with P+H IV, PH FDC SC, or trastuzumab SC in the clinic. The main objective is to enable continuity of care during the COVID-19 pandemic. This study will enroll approximately 200 patients in the United States. Participants with early or metastatic HER2+ breast cancer will be enrolled in this study. Participants with metastatic HER2+ breast cancer will receive treatment every 3 weeks and continue treatment unless early cessation is necessary due to disease recurrence, disease progression, unacceptable toxicity, participant withdrawal of consent, or per physician's recommendation. Participants with early HER2+ breast cancer will receive PH FDC SC to complete 1 year (up to 18 cycles) of dual blockade, including the P+H IV, PH FDC SC, or trastuzumab SC they received prior to enrolling in this study, unless early cessation is necessary due to disease recurrence, disease progression, unacceptable toxicity, participant withdrawal of consent, or per physician's recommendation. A remote cardiac surveillance substudy will be optional for patients enrolled at select sites. The Sponsor may decide to terminate the study when the COVID-19 pandemic is no longer a risk for this patient population.

  • Analysis of Surgery in Patients Presenting With Stage IV Breast Cancer

    Sorry, in progress, not accepting new patients

    The purpose of this study is to study patients presenting with stage IV breast cancer. Stage IV means that the breast cancer has spread to another part of the body outside the breast. This study is important because in different parts of the country some patients are being offered surgical treatment for the breast tumor and some are not. The doctors do not know if surgery for the breast tumor is helpful in patients with stage IV breast cancer. The doctors will collect information about the patient and their treatment to learn more about how patients and doctors make treatment decisions. The doctor will also collect blood samples and tissue samples for laboratory studies to learn more about tumors that have spread to other parts of the body.
