View clinical trials related to Triple Negative Breast Neoplasms.
Filter by:Triple-negative breast cancer (TNBC) is a group of tumors that occurs mainly in young, premenopausal women and accounts for 10-20% of breast cancers. Over the past decade, the incidence of women diagnosed with early-stage TNBC has significantly increased due to the widespread use of screening mammography. Treatment of patients with localized TNBC mainly involves surgery and (neo)adjuvant chemotherapy with or without radiotherapy. However, the benefit of chemotherapy may be controversial in patients with early-stage TNBC defined by small size and absence of lymph node involvement, and with significant tumor lymphocyte infiltration. The ETNA study is a phase II trial designed to evaluate a chemotherapy de-escalation strategy in patients with TNBC T1b/c N0M0 and stromal TILs (sTILs) ≥ 30%. ETNA comprises two cohorts defined according to the level of TILs and the age of patients. Patients aged > 40 years with 30% ≤ sTILs < 50% and those aged ≤ 40 years with 30% ≤ sTILs < 75% will be included in the cohort 1 and will receive adjuvant pembrolizumab 200 mg every three weeks for 9 cycles and Paclitaxel 80 mg/m² weekly for 12 cycles. Patients aged > 40 years with sTILs ≥ 50% and those aged ≤ 40 years with sTILs ≥ 75% will be included in cohort 2 and will not receive adjuvant treatment, they will undergo standard surveillance every six months.
This phase Ib trial tests the safety, side effects and best dose of anti-HLA-A2/NY-ESO-1 T-cell receptor (TCR)-transduced autologous T lymphocytes (A2-ESO-1 TCR-T cells) in treating patients with NY-ESO-1 overexpression positive triple negative breast cancer (TNBC) that has come back after a period of improvement (relapsed/recurrent) or that does not respond to treatment (refractory), and that may have spread from where it first started (primary site) to nearby tissue, lymph nodes (advanced) or to other places in the body (metastatic). NY-ESO-1 is an antigen found on the surface of many different types of tumor cells including TNBC. Antigens make it possible for immune cells to recognize and kill germ cells that invade the body, however, it is more difficult for immune cells to recognize antigens on tumor cells. T cells are a special type of immune cell in the blood. These T cells may be trained to recognize the NY-ESO-1 antigen on tumor cells, allowing the T cells to attack and kill those tumor cells. The A2-ESO-1 TCR-T cells are T cells that have been removed from the patient's blood through a process called leukapheresis and then changed in the laboratory to recognize NY-ESO-1 on tumor cells. When given back to the patient, these A2-ESO-1 TCR-T cells find and attack tumor cells that express NY-ESO-1. Chemotherapy drugs, such as cyclophosphamide and fludarabine, 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. They are given before the T cells to support optimum activity of the A2-ESO-1 TCR-T cells. IL-2 (aldesleukin) is in a class of drugs known as cytokines. It is a man-made version of a naturally occurring protein that stimulates the body to produce other chemicals which increase the body's ability to fight cancer. A2-ESO-1 TCR-T cells may kill more tumor cells in patients with recurrent or refractory advanced or metastatic TNBC that overexpresses NY-ESO-1.
The goal of this clinical trial is to evaluate the efficacity and safety of pembrolizumab and capecitabine compare to pembrolizumab alone, on the invasive disease-free survival, in participants who have triple negative breast cancer (TNBC) with residual disease after neoadjuvant chemotherapy associated with pembrolizumab.
The diverse group of breast tumors known as triple-negative breast cancer (TNBC) which is lethally and deadly type of breast cancer and insensitive to endocrine therapy and HER2-targeted therapy because it lacks the expression of estrogen, progesterone, and human epidermal growth factor receptors TNBC makes up almost 15% of all invasive breast cancers, and of all breast tumor subtypes, it has the worst overall survival and the highest rate of metastatic occurrence. Cytotoxic chemotherapy is the main established systemic therapy for early and advanced TNBC disease at the moment because there is no authorized targeted therapy. Despite the fact that chemotherapy greatly improves clinical outcomes for TNBC patients, recurrence rates are still high and TNBC cancers frequently develop chemotherapeutic drug resistance ). In light of the few available therapy choices, so few choices for this subtype of breast cancer, and many cases are resistant to chemotherapy and recurrent and with a risk of high metastasis from previous literature and many experimental studies, the target of glucose environment is a promising weapon against this deadly type of breast cancer so glucose deprivation from tumor cells may cut the glucose entry as fuel to these cancer cells so this study uses a substitute energy fuel by using alkaline glucosodiene which is chemically invented by Maher M.AKL
This is an open-label, single-arm phase II trial of first-line treatment with trastuzumab deruxtecan (T-DXd) for patients with locally advanced or metastatic triple-negative breast cancer, luminal androgen receptor subtype (TNBC-LAR) with low HER2 expression.
To explore the efficacy and safety of TROP2 in the treatment of ABC
In this study, individuals with triple-negative breast cancer will receive either a platinum-based or non-platinum-based preoperative chemotherapy treatment. This study will help us identify which option is the most effective and safe.
The goal of this clinical trial is to learn about the efficacy and safety of short-term sintilimab in combination with taxane and carboplatin for neoadjuvant therapy in female early-stage triple-negative breast caner patients aging from 18 to 70 years with unilateral and invasive primary lesions above 1cm. The main questions it aims to answer are: 1. Does short-term sintilimab in combination with taxane and carboplatin lead to acceptible pathological complete response (pCR) rates, objective response rates (ORR), event-free survival (EFS) and overall survival (OS)? 2. Does short-term sintilimab in combination with taxane and carboplatin lead to less adverse events than regular-term ICIs reported in literature? Participants will be given 2 cycles of sintilimab, in combination with 4 cycles of taxane and carboplatin before surgery. An optional core-needle biopsy is performed after completing 2 cycles of sintilimab. All participants will be given regular follow-up post surgery according to ASCO guidelines.
This study is a single arm, phase II pilot design. The study will evaluate the safety and efficacy of intralesional immunotherapy (e.g. IL-2) in early stage TNBC. The overall objective of the research study is to advance our knowledge of novel immunotherapies and routes of administration for the treatment of TNBC HYPOTHESES: Neoadjuvant treatment of TNBC with intralesional IL-2 is safe and well tolerated and can produce a pathological response. Aim 1: Examine the safety and possible efficacy of a novel neoadjuvant intralesional intervention (IL-2) for patients with early-stage TNBC.
Summary Points: 1. High Risk Breast Cancers: Triple negative cancer is considered high risk due to high rate of local and systemic failure. Newer innovative treatment strategies are needed to improve systemic control of disease and survival. 2. Immune system modulation: is an emerging modality in cancer treatment. Tumor antigens can stimulate T cells to identify and destroy cancer cells. Cancers express "altered self" antigens that tend to induce weaker responses than the "foreign" antigens expressed by infectious agents. Thus, immune stimulants and adjuvant approaches have been explored widely. Opportunities to develop effective cancer vaccines may benefit from seminal recent advances in understanding how immunosuppressive barricades are erected by tumors to mediate immune escape. This concept is precisely applicable to triple negative breast cancer due to their antigenicity. Checkpoint inhibitors are an attractive method for treatment of high-risk breast cancers. However, to leverage the efficacy of checkpoint inhibition, approaches are needed to enhance delivery of cancer antigens to the T cells. 3. Cryoablation: offers an efficacious and safe method to enhance tumor antigen presentation to the immune cells while destroying the primary tumor. This ablation method is superior by virtue of antigen preservation in situ despite toxicity to the tumor cell. Impact of cryoablation in enhancing immunological responses in tumor microenvironment are well established; however, cryoablation can also cause tumor antigen tolerance via non-specific stimulation of T cells. 4. Rationale for combining cryoablation and checkpoint inhibitors: Since checkpoint inhibitors curtail the tolerance developed by tumor antigens, and cryoablation enhances antigen presentation and T cell recruitment, it is intuitive that combination of these two approaches presents an ideal opportunity to leverage the benefits of both approaches while curtailing the limitations of either. Therefore, the investigators hypothesize in this study that their combination will improve the response rate and the degree of response.
