Active clinical trials for "Breast Neoplasms"

The utilization of tamoxifen is considerably high in Indonesia, with about 170,000 tamoxifen prescriptions filed in 2015. It is metabolized by the enzyme CYP2D6, resulting in its active metabolite, endoxifen, which has been proven to be effective in the prevention and treatment of breast cancer. Studies showed the CYP2D6 gene has more than 100 variants; some of which are linked with reduced drug activity, while others do not have any pathological implications. The metabolizer profile of these variants is generally grouped into Ultra-rapid, Normal, Intermediate, and Poor Metabolizers (UM, NM, IM, and PM, respectively). In our previous study (NCT04312347), the investigators recruited 150 breast cancer patients who were taking adjusted dose of tamoxifen daily based on their CYP2D6 phenotype. Although the investigators have measured the endoxifen level of the patients with adjusted treatment, the clinical outcomes of the study are not yet conclusive.

HR-positive breast cancers accounts for about 50% to 60% of all breast cancer patients. Neoadjuvant Chemotherapy is the core treatment mode for this type of breast cancer, and endocrine therapy can be used in some low-risk patients. However, the pathological complete response (pCR) rate obtained is low. HER2 is an important prognostic indicator and therapeutic target for breast cancer. Nearly 60% of HR-positive breast cancers have low expression of HER2, and antibody-drug conjugates (ADC) targeting HER2 may achieve better efficacy in this subtype.

The study is designed to compare the clinical benefit following treatment with aromatase inhibitor in combination with metronomic capecitabine versus aromatase inhibitor alone in women with hormone receptor-positive, Her2-negative advanced breast cancer who have not received prior systemic anti-cancer therapies for their advanced/metastatic disease.

This phase II trial studies the side effects and how well cyclophosphamide, paclitaxel, and trastuzumab work when given after surgery in treating patients with stage I-II human epidermal growth factor receptor (HER2/neu) positive breast cancer (confined to the breast or the breast and lymph nodes under the arm). Drugs used in chemotherapy, such as 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 trastuzumab, may interfere with the ability of tumor cells to grow and spread. Giving cyclophosphamide, paclitaxel, and trastuzumab after surgery may help prevent the cancer from coming back.

This randomized phase II trial studies how well cisplatin works with or without veliparib in treating patients with triple-negative breast cancer and/or BRCA mutation-associated breast cancer that has come back (recurrent) or has or has not spread to the brain (brain metastases). Drugs used in chemotherapy, such as cisplatin, 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. PARPs are proteins that help repair DNA mutations. PARP inhibitors, such as veliparib, can keep PARP from working, so tumor cells can't repair themselves, and they may stop growing. It is not yet known if cisplatin is more effective with or without veliparib in treating patients with triple-negative and/or BRCA mutation-associated breast cancer.

This phase II trial studies how well nab-paclitaxel and atezolizumab before surgery work in treating patients with triple negative breast cancer (breast cancer cells that do not have estrogen receptors, progesterone receptors, or large amounts of human epidermal growth factor receptor 2 protein). Drugs used in chemotherapy, such as nab-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. Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving nab-paclitaxel and atezolizumab before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. This drug combination before surgery may be an effective treatment for triple negative breast cancer.

This research study is studying a drug called eribulin combined with standard treatment as a possible preoperative treatment for HER2 negative inflammatory breast cancer.

This randomized clinical trial compares two systemic treatments for HER2-positive breast cancer. The treatments are given either prior to breast surgery (as neoadjuvant treatment) or after breast surgery (as adjuvant treatment). In the investigational group (Group A) the study participants will receive a combination of two drugs directed at HER2 (two anti-HER2 antibodies) plus a chemotherapy agent (docetaxel) for a brief duration, and the patients allocated to the comparator group (Group B) will be treated with chemotherapy plus one anti-HER2 treatment (trastuzumab) for one year.

This is a randomized trial for patients with metastatic hormone receptor (HR)-positive human epidermal growth factor receptor 2 (HER2)-negative breast cancer who have progressed on an aromatase inhibitor plus a CDK4/6 inhibitor (either palbociclib or ribociclib) to either fulvestrant alone or fulvestrant with ribociclib (LEE-011). The purpose of the trial is to determine whether there is continued benefit for patients to remain on a CDK4/6 inhibitor at the time of switching anti-estrogen therapy. As ribociclib and palbociclib have a similar toxicity and drug profile and mechanism of action, we feel that it is appropriate for patients to receive either drug with an aromatase inhibitor prior to randomization.

This phase I trial studies the side effects and best dose of Galunisertib when given together with paclitaxel in treating patients with androgen receptor negative or triple negative breast cancer that has spread to other places in the body. Some tumors need growth factors, which are made by the body's white blood cells, to keep growing. Galunisertib may interfere with growth factors and help cause tumor cells to die. 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. Giving Galunisertib together with paclitaxel may kill more tumor cells.
