Active clinical trials for "Breast Neoplasms"

Docosahexaenoic acid (DHA) is an omega-3 long chain polyunsaturated fatty acid (n-3 LCPUFA). N-3 LCPUFA are essential fatty acids in the diet. The majority of n-3 LCPUFA in the diet is alpha-linolenic acid (ALA). While DHA can be synthesized from ALA and other n-3 LCPUFA in the body, endogenous synthesis is low. Consequently, the only way to significantly increase levels of DHA in tissues is by directly consuming this fatty acid. Common sources of DHA are fatty fish, fish oil and omega-3 supplements and fortified foods. DHA is readily incorporated into membrane phospholipids and induces changes in the properties of the cell membrane including altered fluidity; permeability and membrane transport as well as activity of membrane bound receptors and enzymes. It is well established that changes in membrane DHA has multiple effects in the body, including modulation of neurological, immune, and cardiovascular functions. In breast cancer, DHA increases sensitivity of breast cancer cells to different chemotherapeutic agents, and in animal models of breast cancer, dietary DHA decreases tumour growth. The investigator's preclinical studies demonstrate that DHA increases efficacy of both doxorubicin and docetaxel, two agents commonly used in the adjuvant setting for breast cancer treatment. Furthermore, DHA mitigates chemotherapy induced weight loss in mice, and reduces paclitaxel toxicities in breast cancer patients, strongly indicating that DHA protects against toxicity in normal tissues. Directly relevant to this study, increased DHA in breast adipose tissue correlates with improved response to chemotherapy, and increased dietary intake of n-3 LCPUFA, including DHA, results in increased DHA incorporation in breast adipose tissue. Lastly, in advanced metastatic breast cancer, DHA supplementation correlated with improved outcomes in a subset of patients. Consequently, the Investigators hypothesize that the therapeutic index (efficacy: toxicity ratio) will be improved with the addition of DHA. In this clinical trial, the Investigators will explore the benefit of DHA supplementation in combination with neoadjuvant chemotherapy in patients with early breast cancer. RESEARCH QUESTION & OBJECTIVES: The Investigators propose to evaluate incorporation of DHA in women with breast cancer in treatment naïve patients in combination with chemotherapy, and assess potential benefit of DHA supplementation in breast cancer patients, using change in Ki67 labeling index (marker of proliferation) as a marker of efficacy. This study will further investigate the relationship between DHA in plasma phospholipids (as a potential biomarker of tumour incorporation) and effect on systemic immune function. METHODS: Patients directed to receive chemotherapy will receive capsules, each containing a minimum of 400 mg of DHA in the form of DHA enriched triglyceride oil or placebo (corn/soy oil blend) to be taken orally (11 capsules/day, throughout day as preferred by participant) for a total of 5 g DHA or placebo, for 12-18 weeks (84-126 days) beginning at the start of the first cycle of chemotherapy, and continued throughout 4-6 cycles of chemotherapy (3 weeks/ cycle). DHA will be discontinued 21 days after the last administration of cytotoxic chemotherapy. Tumour biopsies at baseline and post surgical removal will be assessed for Ki67 status as well as for markers of apoptosis and stem cell presence (by immunohistochemistry). Blood samples taken at baseline prior to each round of chemotherapy will be assessed for immune markers and plasma phospholipid content.

This is an open-label, single arm, phase II trial to evaluate the efficacy and safety of 500mg Fulvestrant (Faslodex®) in ESR1 mutated postmenopausal women with hormone receptor positive, HER2 negative locally advanced or metastatic breast cancer after previous aromatase inhibitor therapy. Fifty patients will be enrolled and treated with 500 mg Fulvestrant until disease progression or study closed. Treatment will continue until disease progression, unless any of the criteria for treatment discontinuation are met first. If a patient progresses during the treatment period, the patient must be withdrawn from the treatment and further treatment will be at the investigator's discretion.

The investigators hypotheses that paclitaxel combined with cisplatin in a weekly-based regimen as adjuvant chemotherapy is more effective for high risk, HER2 negative breast cancer .

This is a single-center, open-label, dose-escalating study to evaluate the safety, pharmacokinetics, immunogenicity, and preliminary efficacy of single and multiple subcutaneous injection TK006 in patients with breast cancer-related bone metastases.

This phase II trial aims to study the efficacy and safety of 12 weeks adjuvant docetaxel plus trastuzumab in patients with tumors ≤1cm, node-negative, HER2-positive breast cancer.

This is an open labelled study. It was designed to evaluate the safety of multiple-dosing of TK006 in patients with breast cancer-related bone metastases. This trial is the extension of a core study: Phase 1 Trial of a Fully Human Monoclonal Antibody of Receptor Activator for Nuclear Factor-κ B Ligand (RNAKL, TK006) Safety, Pharmacokinetics, and Pharmacodynamics in Patients With Breast Cancer-related Bone Metastases (NCT 03239756).

The purpose of this study is to microscopically examine breast cancer cells of pre-menopausal and post-menopausal women before and after exposure to one of the two commonly used breast cancer drugs, tamoxifen or fulvestrant.

The hypothesis of this study is to discover if the oral Etoposide plus Anlotinib can shrink or slow the growth of pretreated advanced TNBC. It is a single-arm, multicenter phase II clinical study of oral etoposide combined with antinib in the treatment of recurrent or metastatic triple-negative breast cancer

The role of neoadjuvant chemotherapy (NAC) in breast cancer is well established. Increasing rates of pathologic complete response (pCR) has increased de-escalation of surgical techniques. The objective of the study is to evaluate new radiologic techniques that can accurately detect complete response in order to eliminate breast surgery. . . Currently, there are several imaging techniques for NAC response assessment (magnetic resonance imaging -MRI-, mammography and ultrasound), with good correlation in partial response, but they lack power in predicting complete pathological response. The investigators propose to use IVIM (Intravoxel incoherent motion), Kurtosis (DKI by Diffusion Kurtosis imaging) and diffusion tensor image (DTI) in MRI, contrast enhancement mammography and shear wave elastography for the evaluation of the response to systemic treatment in breast cancer patients. In order to validate the technique, in those patients with a radiological complete response by all the radiological imaging methods, a vacuum-assisted biopsy will be performed before surgery. After that, a comparison will be done between the results of the pre surgical biopsy and the definitive pathology of the specimen. So the investigators can evaluate if patients with complete radiological response after NAC, can be spared breast surgery.

The international treatment guidelines now include recommendations for the use of CDK 4/6 inhibitors in combination with hormone agents for the treatment of postmenopausal women with hormone-receptor-positive/HER2-negative ABC as the first-line standard therapy in endocrine sensitive patients. Nevertheless, it is generally thought that chemotherapy is associated with greater and earlier tumor response, especially in case of high burden of disease. In a retrospective analysis of real-world clinical practice (2002-2012) from US, only 60% of patients initiated ET as the first treatment following metastatic diagnosis . In the real-life world of China, a large number of HR+/HER2- ABC patients with non-visceral crisis also received chemotherapy in first-line treatment, even though the ORR is similar compared with CDK4/6 inhibitors with endocrine therapy. Zhejiang Cancer Hospital retrospective analysis of 5 cases of advanced breast cancer first-line use of Ibance + ET, they were evaluated within 50 days (from 27days to 50days). Based on the early response time observed in real-world data mentioned above, it is proposed a prospective study to further observe the tumor reduction rate in real-world, including to identify the time of patient symptom improvement according to the quality of life scale.
