Active clinical trials for "Triple Negative Breast Neoplasms"

The INSTIGO study aims to assess a plasma protein profile at different stages of patient follow-up as a predictive factor of metastatic recurrence in triple negative breast cancer. It also aims to look at other potential biomarkers of metastatic relapse such as Tumor-infiltrating Lymphocytes, circulating tumor DNA, figurative elements in blood, or a tumor RNA signature.

This phase II trial tests the safety, side effects, and whether dendritic cell-based treatment and pembrolizumab work in treating patients with triple negative breast cancer that has spread to other places in the body (metastatic) or cannot be removed by surgery (unresectable). The term triple-negative breast cancer refers to the fact that the cancer cells don't have estrogen or progesterone receptors (ER or PR) and also don't make any or too much of the protein called HER2 (the cells test "negative" on all 3 tests). Dendritic cell-based treatment works by boosting the immune system (a system in our bodies that protects us against infection) to recognize and destroy the cancer cells. Pembrolizumab, is an immune checkpoint inhibitor drug, that works by targeting molecules that act as a check and balance system for immune responses. Immune checkpoint inhibitor drugs are designed to either "unleash" or "enhance" the cancer immune responses that already exist by either blocking inhibitory molecules or by activating stimulatory molecules. Giving dendritic cell-based therapy and pembrolizumab may decrease symptoms and improve quality of life in patients with triple negative breast cancer.

To investigate the efficacy and safety of terbinumab combined with chemotherapy (epirubicin + cyclophosphamide → nab-paclitaxel + carboplatin) in neoadjuvant therapy of triple-negative breast cancer after HIFU.

Multicenter, retrospective and prospective, cohort, observational study evaluating the clinical efficacy and tolerability of Eribulin as second-line treatment in accordance with the indications authorized by AIFA in patients with triple negative advanced breast cancer in a real world setting.

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.

TNBC is known for poor prognosis, aggressive patterns of disease, and significant molecular heterogeneity. (Neo)adjuvant chemotherapy (NACT) is standard of care in all node-positive and in node-negative patients with a tumour size >5 mm according to current National Comprehensive Cancer Network (NCCN) guidelines. However, TNBC patients with lower stage disease do clearly have a better prognosis compared to more advanced stages. Patients with stage I-II node-negative disease have 3-5 year iDFS rates of 80-90% (with majority of relapses within the first three years) as shown in several trials.Although survival results appear much better in the lower vs. higher stages, there is a high clinical need in this most common group of TNBC patients in Western Europe and USA.

breast cancer is the most common cancer in women. With more than 1 in 10 new cancer diagnoses each year, It is the second most frequent cancer-related death among women worldwide. Breast cancer develops slowly, and the majority of cases are found through routine screening. breast cancer-causing deaths among women all over the world and increased in the last few years even though the treatment is advanced like immunotherapy chemotherapy by yet no treatment for triple-negative breast cancer zinc and competition between znt1 and zip6,10 at breast cancer cells. Is zinc ionophore like quercetin and EGCG has a role, In a novel experimental study zinc is a trace metal that has many roles in cells, enzymatic activity, and gene regulations, and also for the integrity of DNA. Zinc transporters (zinc related -proteins such as ZIPs, and ZnTs are affected by triggers factors like cytokines and growth factors. There are two large families of zinc transporters like ZIPs ( 14 members) and ZnTs family (10 members), ZIPS family cause an influx of zinc from the extracellular to the cytoplasm and also from intracellular organelles like endoplasmic reticulum or Golgi or mitochondria in contrast to ZnTs which cause an influx of zinc from the cytoplasm to intracellular organelles. ( lower cytoplasmic zinc) (1) Breast cancer deaths occurred from metastasis; Catalytic enzymes called proteases like cathepsin L are frequently overexpressed in aggressive cancers. Breast tumor metastatic potential is correlated with macrophage presence. These macrophages associated with tumors frequently adopt an M2-like pro-tumorigenic phenotype, which results in the production of growth hormones and proteases, notably the lysosomal protease cathepsin L. Because cathepsin L is commonly released by breast cancer cells and aids in tumor invasion, metastasis, and angiogenesis. It is expected that cathepsin L secretion by both tumor-associated macrophages and neoplastic cells would promote the metastatic phenotype because cathepsin L is widely produced by breast cancer cells and helps with tumor invasion, metastasis, and angiogenesis. (2) this study target new mechanisms and achieves the best management as some types of cancer breast like triple-negative breast cancer (TNBC) no definite treatment so we target the following pathways and epigenetic processes by these adjuvant compounds which have a promising role in the immunity like EGCG, Quercetin, Zinc, Metformin so our team will discuss novel methods to achieve the best efficacy from chemotherapy

This phase II trial tests how well propranolol and pembrolizumab work to cause tumor re-sensitization and therefore treatment in patients with triple negative breast cancer that has not responded to previous checkpoint inhibitor therapy (refractory), cannot be removed by surgery (unresectable) or has spread from where it first started (primary site) to other places in the body (metastatic). Propranolol is a drug that is classified as a beta-blocker. Beta-blockers affect the heart and circulation. Beta-blockers, like propranolol, may help to counteract effects of certain stress hormones produced by the body during cancer treatment and may increase the effectiveness of the pembrolizumab. Pembrolizumab is a drug that is classified as an immune checkpoint inhibitor. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Propranolol may be able to re-sensitize the cells of the immune system to respond to the checkpoint inhibitor pembrolizumab in patients with checkpoint inhibitor refractory metastatic or unresectable triple negative breast cancer.

Triple-negative breast cancer (TNBC) is defined by the absence of estrogen receptor (ER), progesterone receptor (PgR), and human epidermal growth factor receptor 2 (HER2) expression on cancer cells. TNBCs accounts for 15-20% of all breast cancers (BC).1 It is characterized by a worse prognosis, increased risk of metastasis to vital organs and a relative lack of therapeutic target if compared to other BC subtypes.2 Therefore, the identification of new molecular targets and therapeutic strategies is a critical need in both early and metastatic setting. TNBC appears to be more immunogenic compared to other BC6. Immunotherapy has recently changed the landscape of therapeutic options in TNBC. Recent clinical trials have shown a significant clinical benefit in patients with metastatic TNBC treated with a combination of chemotherapy and anti PD-1 agents.11-12-13-14-15 In particular, results from IMPASSION 130 trial showed a significant benefit in both progression free survival (PFS) and overall survival (OS) in PD-L1 positive (PD-L1+) patients treated with a combination of atezolizumab and nab-paclitaxel.20 However, about 70% of PD-L1+ patients has experienced a disease progression after one year and about 50% was alive at 2 year. Moreover, no difference in survival endpoint has been seen in PD-L1 negative (PD-L1-) population, with an increase of toxicity and costs related to the addition of a checkpoint-inhibitor. Therefore, the identification of novel biomarkers in addition to PD-L1 and the combination of several biomarkers in a profile with higher predictive capacity is considered an area of urgent clinical need. Some immune-related features that can be identified in tumor microenvironment have been demonstrated to be independent prognostic and predictive factors: TILs, PD-L1, CD73. Tumour-infiltrating lymphocytes (TILs) control the clinical progression of various types of cancer7. Breast cancer with higher levels of infiltrating CD8+ cytotoxic T cells have been associated with better patient survival8. Moreover, high levels of stromal CD8+ TILs (sTILs) correlate with higher probability of pCR9. Not only quantitative, but also qualitative analysis of TILs is a promising research area. Some studies suggest that different subtypes of TILs may have an opposite role in tumor microenvironment allowing the induction of both immune activating (es. CD8+) or immune suppressive (es FOXP3+) environment8-9-10. The interaction between programmed cell death protein 1 (PD-1) and its ligand (PD-L1) represents one of the principal mechanisms of immune escape and a therapeutic target for several malignancies13-14. PD-1/PD-L1 interaction attenuates lymphocyte activation and promotes T-regulatory cell development and function, allowing to terminate the immune response15. In breast cancer the prognostic role of PD-1/PD-L1 axis is still uncertain with limited and contrasting data. PD-L1 positivity (≥1%) on immune cells (IC) is the clinical most used threshold, according to the results of IMPASSION 130 trial.18-24 Recently, CD73 has been identified as a possible further molecular immunosuppressive target in triple negative breast cancer28. CD73 is expressed on the surface of tumoral cells, stromal cells and immunological cells. By increasing extracellular levels of adenosine monophosphate , CD73 suppresses immune responses. CD73 has been found to be overexpressed in several types of human cancers, and it has been associated with a poor prognosis29-30-31. Particularly Loi et al demonstrated that high CD73 expression is associated with poor prognosis in TNBC and to a low rate of pathological complete response32. We defined a tissue immune profile positive (TIP+) as the simultaneous presence of TILs≥50%, CD73≤40% and PD-L1≥1%. Any other combination was defined as TIP negative (TIP-) In conclusion, we will evaluate the association between TIP and clinical outcomes (ORR, PFS, OS).

This clinical trial aims to evaluate the efficacy, safety, and exploratory measures of liposomal doxorubicin and carboplatin combination therapy in the adjuvant setting for early stage triple negative breast cancer (TNBC) patients. The primary objective is to determine the effectiveness of liposomal doxorubicin and carboplatin in reducing the risk of recurrence for early stage TNBC patients. The secondary objectives involve characterizing the safety and toxicity profile of the combination therapy. Adverse events rates will be assessed using the Common Terminology Criteria for Adverse Events (CTCAE) version 5.0. The exploratory objectives of the study focus on evaluating changes in circulating tumor DNA (ctDNA). This measure will provide insights into the potential utility of ctDNA as a biomarker for treatment response and disease progression. By addressing these objectives, the study aims to contribute to the understanding of the benefits and risks associated with liposomal doxorubicin and carboplatin combination therapy in the adjuvant setting for early stage TNBC, potentially leading to improved treatment outcomes and patient care.
