Active clinical trials for "Breast Neoplasms"

The primary purpose of this study is to characterize the safety and tolerability of tucatinib (MK-7119) in Chinese participants with human epidermal growth factor receptor 2 positive (HER2+) advanced breast cancer, gastric or gastroesophageal junction adenocarcinoma (GEC), and colorectal cancer.

Approximately 24,000 women attend a follow-up care program after end of primary treatment for breast cancer (BC) in Denmark. There is no well-conducted, larger randomized controlled trials (RCT) outlining a gold standard for follow-up programs ensuring early detection of recurrence, good management of symptoms and cost-effectiveness. The primary aim of this randomised, controlled trial is to test whether a nurse-led individually tailored symptom management program (MyHealth) will significantly reduce reported symptoms among BC patients following primary treatment compared to physician-led scheduled follow-up. Secondary, the investigators will examine patient activation (self-management), anxiety, depression, fear of recurrence, work ability, time to recurrence, overall survival, health behavior changes, health care utilization and financial costs in the two arms. The MyHealth program provides patients with a nurse-led education focusing on management of symptoms, an electronic platform to report symptoms to the nurses and support in symptom management and navigation of patients to appropriate health care services.

This is a multi-center, randomized phase II trial that will randomise women with ER-positive, HER2-negative (Human Epidermal Growth factor Receptor 2-negative) metastatic or locally relapsed breast cancer in a ratio of 1:1 to receive a metronomic regimen of vinorelbine plus cyclophosphamide and capecitabine, or the conventional paclitaxel monotherapy.

This study has 2 phases: Phase 1 (dose escalation) and Phase 2 (dose expansion). The goal of Phase 1 of this clinical research study is to find the highest tolerable dose combination of selumetinib and olaparib that can be given to patients who have solid tumors that are advanced or recurrent (has returned after treatment). The goal of Phase 2 is to learn if the highest tolerable dose combination found in Phase 1 can help to control advanced or recurrent solid tumors. The safety of the study drug combination will also be studied in both parts. This is an investigational study. Selumetinib is not FDA approved or commercially available. It is currently being used for research purposes only. Olaparib is FDA approved and commercially available for the treatment of ovarian cancer that has a certain type of genetic mutation (change). It is considered investigational to use selumetinib in combination with olaparib to treat advanced or recurrent cancer. The study doctor can explain how the study drugs are designed to work. Up to 90 participants will be enrolled in this study. All will take part at MD Anderson.

This research study is studying three combinations of drugs as treatments for breast cancer. The drugs involved in this study are: Fulvestrant Fulvestrant with Palbociclib Fulvestrant with Palbociclib and Avelumab

This study is a randomized, open-label, multicentric, phase III trial conducted in patients receiving aromatase inhibitor and palbociclib as first line therapy for estrogen receptor (ER)-positive HER2-negative metastatic breast cancer and which aims to evaluate, at the onset of ESR1 mutations in circulating tumor DNA, the efficacy of a change of the hormone therapy (aromatase inhibitor (AI) changed to fulvestrant) combined to palbociclib, together with the safety of hormone therapy and palbociclib combination in the overall population.

This is a multicenter run-in phase Ib / roll-over phase II study of triple targeted drug combination (HER2-targeted small molecule inhibitor tucatinib, CDK4/6 inhibitor palbociclib and aromatase inhibitor letrozole) as a first or second line of therapy in patients with metastatic hormone receptor positive and HER2-positive breast cancer.

This phase II trial studies how well hypofractionated partial breast irradiation works in treating patients with early stage breast cancer. 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. Treating only the part of the breast where the cancer started may lead to fewer side effects than standard treatment.

This is an open-label, three-part, multiple-dose study to evaluate safety, tolerability, and efficacy of U3-1402 in patients with HER3-positive metastatic breast cancer. HER3 is a unique member of the human epidermal growth factor receptor, which defines a certain type of cancer. The number of patients and treatment cycles are not fixed in this study. Subjects who continue to derive clinical benefit from the study treatment in the absence of withdrawal of consent, progressive disease (PD), unacceptable toxicity, or death may continue the study treatment until the end of the trial.

Triple-negative breast cancer is a subtype of breast cancer that is clinically negative for expression of estrogen and progesterone receptors (ER/PR) and HER2 protein. It is characterized by its unique molecular profile, aggressive behavior, distinct patterns of metastasis, and lack of targeted therapies. Although not synonymous, the majority of triple-negative breast cancers carry the "basal-like" molecular profile on gene expression arrays. Although sensitive to chemotherapy, early relapse is common and these cancers show a predilection for visceral metastasis, including brain metastasis. Targeted agents, including epidermal growth factor receptor (EGFR), vascular endothelial growth factor (VEGF), and poly (ADP-ribose) polymerase (PARP) inhibitors, are currently in clinical trials and hold promise in the treatment of this aggressive disease. Multiple independent data sets have revealed that the triple negative type of breast cancer carries a poor prognosis. It is unclear whether the poor prognosis of triple negative breast cancer is due to poor therapy options or inherent aggressiveness. Given their triple negative receptor status, these tumors are not amenable to conventional targeted therapies for breast cancer, such as endocrine therapy or trastuzumab, leaving only chemotherapy in the therapeutic armamentarium. Patients on metformin showed a 30-40% protection against all forms of cancer. Recent pilot studies carried out using population registries raise the possibility that metformin may reduce cancer risk and/or improve cancer prognosis. One showed an unexpectedly lower risk of a cancer diagnosis among diabetics using metformin compared with a control group of diabetics using other treatments ; another showed lower cancer-specific mortality among subjects with diabetes using metformin compared with diabetics on other treatments. Metformin is a biguanide known to be an insulin sensitizing agent which promotes reduced circulating insulin and glucose levels in hyper-glycaemic and hyper-insulinaemic patients. Metformin activates the AMP dependent kinase, attenuates insulin and IGF-1 stimulated proliferation in breast cancer cells and a general decrease in protein synthesis in vitro. Western blot analysis indicated that metformin stimulates AMPK phosphorylation in a dose-dependent manner. AMPK activation is associated with decreased phosphorylation of mTOR and S6 kinase. While metformin reduces breast carcinoma cell proliferation both in vitro and in vivo, the activation of AMPK leads to significant VEGF production, angiogenesis and tumor progression. This must be taken into consideration when it is applied in as a therapeutic regimen.
