Active clinical trials for "Breast Neoplasms"

Breast cancer patients often receive systemic drugs as the initial curative treatment of their disease. The initial systemic therapy leads to a variable degree of tumor shrinkage. At present, there is no evidence-based consensus among breast surgeons on the optimal extent of resection after considerable tumor shrinkage and whether resection margin should be designed according to the tumor extent before treatment or the extent after treatment. This trial will help determine the optimal extent of resection in tumors that exhibits a significant change in volume after primary systemic therapy.

This is a randomized, open, parallel-controlled, multicenter, phase II/III, seamless design clinical trial to compare the efficacy and safety of RC48-ADC with capecitabine + lapatinib in locally advanced or metastatic human epidermal growth factor receptor 2 (HER2) positive breast cancer and HER2-positive advanced breast cancer with liver metastasis.

This is an Italian, single center, randomized, phase II study. ATRA (all-trans retinoic acid) and derivatives (retinoids) are promising anticancer agents and exert their anti-proliferative, differentiating and apoptotic effects through the nuclear retinoic acid receptors, including RARα (retinoic acid receptor alpha). Although the clinical use of ATRA in haematological malignancies (Acute Promyelocytic Leukemia, APL) is well established, its use in solid tumors is limited. However, some recent pre-clinical evidence suggests a possible role of ATRA in the treatment of specific subtypes of HR-positive (Hormonal Receptor)/HER2-negative early breast cancer (eBC). Moving from pre-clinical evidence and given the well-known retinoid mechanism of action, The hypotheses is that ATRA contributes to tumor regression in a specific sub-population of eBCs. Using a preoperative "window-of-opportunity" model, aimed at testing the activity of ATRA in combination with anastrozole in postmenopausal women with newly diagnosed, resectable, HR+/HER2- eBCs.

Triple-negative breast cancer (TNBC) accounts for about 20% of clinical breast cancer. Clinical characteristics include early onset, high malignancy and heterogeneity. There is no effective drug target for TNBC, resulting in poor outcomes, high relapse rate and distant metastasis. So, further research on TNBC pathological features is particularly important. Compared with the solvent-based paclitaxel, albumin-bound paclitaxel (nab-P) demonstrates a stronger therapeutic effect. With albumin nanoparticles as a carrier, nab-P increases the concentration of extra-tumor drugs by passing through the albumin receptor (Gp60) transmembrane pathway and the secreted protein acidic and rich in cysteine (SPARC) approach that binds to the extracellular matrix of the tumor. Numerous clinical trials have found that nab-P is superior to the solvent-based paclitaxel in the treatment of breast cancer, especially in breast cancer with poor prognosis. However, the current efficacy of nab-P in the treatment of TNBC has not been fully verified. The mechanism underlying the killing effect of nab-P on TNBC breast cancer cells remains unclear yet. This trial will compare the therapeutic effect of nab-P with solvent-based paclitaxel in TNBC patients, and seek for important scientific clues, scientific evidence, and clinical data for nab-P in the treatment of TNBC.

The aim of the study is to establish clinical evidence for introducing disulfiram and cooper as an active therapy for metastatic breast cancer upon failure of conventional systemic and/or locoregional therapies. Analyses of the following objectives will be performed in the population of patients with metastatic breast cancer: Primary efficacy objective: To evaluate the efficacy of the treatment by assessment of: clinical response rate (RR) clinical benefit rate (CBR) Secondary efficacy objectives: To evaluate the efficacy of the treatment by assessment of: time to progression (TTP) overall survival (OS) Pharmacokinetic objectives: • to determine pharmacokinetic parameters for disulfiram and its active metabolites administered in combination with copper supplements in cancer patient population Safety objectives: • to describe safety profile of disulfiram administered in combination with copper supplements Exploratory objectives: Parallel analysis to assess (identify) potential candidate surrogate biomarkers of disulfiram efficacy, as well as identification (using proteomic, biochemical and molecular genetic studies) of potential predictive biomarkers of disulfiram sensitivity or resistance will be performed. Surrogate biomarker analysis will focus on in vivo ubiquitin-proteosomal system inhibition, cell cycle and DNA damage.

Multicenter open-label, phase II trial, to evaluate the efficacy and safety of nal-IRI in patients with HER2-negative breast cancer, who have documented Central Nervous System (CNS) progression following Whole Brain Radio Therapy (WBRT), Stereotactic Radiosurgery (SRS) and/or surgery, as determined by the Response Assessment in Neuro-Oncology Brain Metastases (RANO-BM) criteria.

This clinical trial is designed to be a multi-center prospective, parallel-controlled Phase III clinical study. In this study, the efficacy of tamoxifen versus toremifene shall be compared in CYP2D6 intermediate/poor metabolizers of premenopausal patients with estrogen receptor-positive early breast cancer.

This is an open label, non randomised, investigator-initiated Phase II study of single agent talazoparib (Talzenna®) in metastatic triple negative breast cancer patients with enriched HRD signature. Approximately 55 subjects will be enrolled in this study to examine the efficacy of talazoparib when given orally 1mg daily for days 1 to 28 for up to 28 months. The study will be conducted using the Simon two-stage phase II design, whereby this study will initially enroll 19 patients with RECIST v1.1 measurable disease with enriched HRD signature (stage I). There will be one interim analysis at the end of stage I and if 3 of the 19 have a response, then no further patient will be accrued. If 4 or more of the 19 patients have a response, then accrual would continue to stage II until a total of 55 patients have been enrolled. This study will be conducted in conformance with Good Clinical Practices. Specific procedures to be performed during the trial, as well as their prescribed times and associated visit windows, are outlined in the Trial Flow Chart.

This purpose of this study is to test if talazoparib is safe and evaluate its response to advanced breast cancer associated with mutation of gene called PALB.
