Filter by:This study will evaluate the effectiveness and safety of the combination of two drugs, Veliparib and Lapatinib, given to participants with metastatic triple negative breast cancer that have undergone previous treatment. Veliparib is an investigational drug and has not been approved by the FDA while Lapatinib has been approved by the FDA for another type of breast cancer. All eligible participants will receive the study medications and not a placebo.
It is a phase II trial to explore the efficacy and safety of cisplatin plus capecitabine in anthracycline and taxane-pretreated metastatic triple negative breast cancer patients.
Triple negative breast cancer (TNBC) is a difficult to treat molecular subtype with a poor survival. TNBC can be divided into at least two molecular entities; BRCA-like and non-BRCA-like. In this trial we would like to investigate whether a molecular subgroup exists within TNBCs that derives a benefit from atezolizumab added to first line chemotherapy.
The trial will evaluate the optimal treatment with nab-paclitaxel in combination with either carboplatin or gemcitabine for patients with triple negative breast cancer.
The purpose of this study is to test whether patients undergoing a breast MRI (magnetic resonance imaging) before breast surgery will have better results after the surgery. Breast tumors are routinely evaluated using mammograms and ultrasound before surgery. This study would like to find out if using MRI in addition to mammography before surgery improves our ability to evaluate tumors and decide what kind of surgery is best for the patient.
Recent clinical studies showed that triple-negative breast cancer patients (ER-/PR-/HER2-) may benefit more from Capecitabine chemotherapy. However, the optimum post-operative adjuvant Capecitabine chemotherapy regimen has not been determined for Chinese population with triple-negative breast cancer. Thus it's necessary to conduct a multi-center Phase III clinical trial to verify efficacy and safety of Capecitabine in the treatment of triple-negative breast cancer. In this study, a prospective, randomized, open, multi-center Phase III clinical study was conducted to compare efficacy and safety of sequential Docetaxel followed by Fluorouracil/Epirubicin/Cyclophosphamide (FEC) and sequential Docetaxel and Capecitabine followed by Capecitabine/Epirubicin/Cyclophosphamide (XEC) as post-operative adjuvant chemotherapy in the treatment of triple-negative breast cancer in Chinese population.
Neoadjuvant (preoperative) chemotherapy is an interesting research tool which allows investigators to test new drugs and/or new schedules with a validated surrogate endpoint, pCR. It also represents an ideal model to evaluate the relationships between treatments and tumor biomarkers. Recent publications have shown that new molecular classifications of breast cancer (intrinsic subtypes) have an important prognostic and predictive value. Using microarrays for gene expression profiling seems to be the best way to perform this classification; nevertheless such assays are not optimally available for common clinical practice. The IHC-based classification systems are still useful, as fresh tissue is not normally available in clinical practice, and has been shown to correlate well with intrinsic classification using gene expression microarrays. Recently the PAM50 gene set provided a risk of relapse score not only in ER-positive, node negative patients (similarly to the Oncotype Dx Recurrence Score) but also in the ER negative disease. Additionally, the PAM 50 assay was highly predictive of neoadjuvant response when considering all patients. This assay added significant prognostic and predictive value to pathologic staging, histologic grade, and standard clinical molecular markers while using an easy technique that can be performed in clinical practice because the qRT-PCR assay can be performed using FFEP tissue. Triple Negative Breast Cancer (TNBC) is defined by a lack of expression of ER, PgR and HER-2. DNA microarray profiling studies have led to the classification of invasive breast carcinoma into five subtypes: luminal A and B, normal breast-like, HER2/neu overexpressing and basal-like subtypes, with clinical implications. Later on, a new subtype, the claudin-low, has been described. Although not synonymous, the majority of TNBCs carry the basal-like breast cancer (BLBC) molecular profile. The triple negative subtype accounts for 11-20% of breast cancer in different studies, whereas in selected cohorts of patients with advanced breast cancer or African-American ethnicity, TNBC may be diagnosed among as many as 23-28%. Patients with TN breast tumors treated with standard chemotherapy have a shorter DFS and OS than non-TNBC, this difference have been shown to be independent from tumor grade, nodal status and treatment in some studies. The peak risk of recurrence occurs within the first 3 years after initial treatment, with the majority of deaths occurring in the first five years. Chemotherapy remains the only systemic treatment option available for TNBC patients. Several studies have shown that TNBC/BLBC is associated with an increased response rate to neoadjuvant chemotherapy when compared with luminal tumors. However, TNBC patients have a significantly decreased DFS and OS in comparison with luminal patients. The largest study exploring response and survival in early stage breast cancer treated with neoadjuvant chemotherapy was reported by Liedtke et al. Although an increase pCR rate was observed among the TNBC patients, they had a shorter lifespan than the non-TN ones. Patients experiencing pCR had an excellent OS regardless of hormone receptor expression, but patients with residual disease had a significantly shorter survival associated with TNBC compared with non-TN ones. This demonstrates that poor OS is derived from chemo-resistant patients (what unfortunately represent > 50% of them). A relevant problem is the differential response to drugs of TN tumors. These tumors are usually treated with multidrug combinations including anthracyclines and taxanes, with pCR´s of 28-32%. Only recently, the results of a few small trials combining platinum salts and taxanes have been reported, with encouraging results (pCR of 44-77%). The taxane-platinum salt combinations have a biological background, since TN not associated BRCA1 mutations are sensitive to taxanes and resistant to anthracyclines and platinum salts are effective in TN tumors probably because a significant proportion of them have functional DNA repair deficiencies. The primary objective of the study is to identify predictors of response to docetaxel-carboplatin in patients with triple negative primary tumors. Response is defined as lack of invasive tumor in breast plus axilla after neoadjuvant chemotherapy (PCR, pathological complete response).
This phase II trial studies how well carboplatin and nab-paclitaxel before surgery work in treating patients with triple negative breast cancer that is inflammatory or has spread from where it started to nearby tissue or lymph nodes. Drugs used in chemotherapy, such as carboplatin and 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. Giving chemotherapy before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed.
Breast cancer triples negatives (TN; 15 % of the cases) are characterized by a high histoprognostic grade, a strong proliferation, a strong metastatic power, and a worse prognosis than the other forms of breast cancer. It is however a heterogenous group for histological and molecular level, but also for evolution. Most of the TN is part of the basal breast cancer subcategory. Until now, the medical treatment is based on chemotherapy. Breast cancers by constitutional mutation of BRCA1 / BRCA2 (5 % of breast cancers) are mostly of basal type and their prognostic seems better that what could be expected from high grade tumours and without hormonal receptors. They would be much more frequent in the TN group. However, at this day, no prospective study was led to estimate this incidence, or to study the intervention of other genes of predisposition, as well to analyse the links between this phenotype and their consequences at the germinal or somatic level, in terms of associated molecular changes and prognosis. The purpose of this study is, on a prospective study, to lead a joined analysis at the germinal level, in search of mutations of the main genes of breast cancer predisposition (BRCA1/2, PALB2, PTEN, PALB2), and at the tumour level (tissue micro-array and transcriptome), by correlating these results to the main clinical parameters. The 5 years relapse-free survival will also be estimated.
This phase II trial studies how well giving eribulin mesylate and carboplatin together before surgery works in treating patients with stage I-III triple-negative breast cancer. Drugs used in chemotherapy, such as eribulin mesylate and carboplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving chemotherapy before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed.
