Active clinical trials for "Breast Neoplasms"

This is a prospective single arm open-label Phase 2 study utilising the combination of Fulvestrant, Metformin and Simvastatin in post-menopausal ER-positive metastatic breast cancer, with the primary endpoint being Clinical Benefit Rate (defined as complete response, partial response or stable disease, equal to or more than 24 weeks). The hypothesis is that the addition of Metformin and Simvastatin to Fulvestrant will improve the Clinical Benefit Rate from 40% (historical data from control arm of PALOMA-3 study) to 60%. A total of 28 patients will be enrolled over a period of 24 months. Eligible patients will receive 500 mg Fulvestrant by intramuscular injection on days 1 and 15 of cycle one and then on day one of each subsequent cycle (28 days). Patients will be given 850mg oral Metformin twice-a-day (based on xenograft models which showed that Metformin had anti-tumor effects at a minimum dose of 1500mg per day), and 20mg oral Simvastatin every night (drawing reference from the investigators' group's window-of-opportunity study), daily throughout the cycle. As part of the in-build safety and tolerability design, all patients will have a lead-in period of 7 days where they receive 850mg oral Metformin twice-a-day and 20mg oral Simvastatin every night. Special adverse events of interest include lactic acidosis, diarrhea, bloatedness, transaminitis and rhabdomyolysis. If no dose-limiting toxic effects (DLT) occur, Fulvestrant will be commenced, and considered the start of cycle 1. If DLT occurs in any of the patients, the combination of Metformin and Simvastatin will be modified for the affected patient as per protocol, with further monitoring for another 7 days. This combination will be deemed safe for that patient if no DLT occurs, following which cycle 1 can officially commence. At the time of study entry, blood samples will be drawn to establish baseline physiological parameters including fasting insulin, glucose, lipids and Homeostasis Model Assessment 2 (HOMA2). In patients who have accessible tumor sites and are willing to provide tissue for translational research, pre- and post-treatment (at end of 8 weeks) biopsies will be taken for correlative biomarker studies. Patients will be evaluated on an 8-weekly basis for toxicities and efficacy assessments during the first 6 months of treatment, followed by 12-weekly thereafter until disease progression, unacceptable toxicities, or patient withdrawal.

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.

The purpose of this study is to evaluate feasibility to treat metachronous multi-site breast cancer oligometastasis with stereotactic body radiotherapy (SBRT) in patients on systemic therapy.

Some studies have demonstrated the efficacy of Abraxane in treating breast cancer in both adjuvant and metastatic settings. Few data is available on Abraxane in neoadjuvant treatment for breast cancer. The aim of this project is to evaluate tailored primary systemic therapy with weekly Abraxane (125mg/m2) Combined With Q3week Epirubicin (100mg/m2) in early operable (stage of T2-4N0-3M0) breast cancer. This study will be an open label non randomized, single arm, single center study.

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.

This study evaluates the addition melatonin and metformin to conventional chemotherapy FDC (Fluoruracil, Doxorubicin, cyclophosphamide) in the treatment of locally advanced breast cancer. Third of patients will receive FDCх6 cycles, other third will receive combination of melatonin and FDCх6 cycles and other patients will receive combination of metformin and FDCх6 cycles.

This study evaluates the addition melatonin and metformin to toremifene in the treatment of locally advanced breast cancer. Third of patients will receive toremifene, other third will receive combination of melatonin and toremifene and other patients will receive combination of metformin and toremifene.
