Filter by:Although many PARP inhibitors did not improve pCR in neoadjuvant studies, it is not an unchallenged conclusion that TNBC does not benefit from use of PARP inhibitors in neoadjuvant therapy.This study is an open-label, two-cohort, multicenter trial. 60 patients with germline BRCA-mutated three-negative early breast cancer are planned to be enrolled and treated with fluzoparib combined with chemotherapy according to tumor response after EC (epirubicin and cyclophosphamide) for 2 cycles.
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. 1. 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. 2. 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 3. 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 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.
The primary scientific question of interest of this study is whether the combination of ociperlimab, tislelizumab and chemotherapy improves progression-free survival (PFS) compared to the combination of placebo, pembrolizumab and chemotherapy as first-line therapy for adult men and women with advanced triple negative breast cancer (TNBC) whose tumors express programmed death ligand 1 (PD - L1) [combined positive score (CPS) ≥10], regardless of study treatment discontinuation or start of new anti-neoplastic therapy.
The purpose of this study is to learn about the effects of the study treatment, Dendritic Cell Vaccine (DCV), to find the highest dose of the study treatment that can be given safely to Breast Cancer patients with Leptomeningeal Disease
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.
The study is being conducted to evaluate VEGFR BP102 with nab-paclitaxe or treatment of physician's choice (TPC) versus nab-paclitaxe or TPC in patients for basal-like immune suppressed (BLIS) subtype of triple-negative breast cancer (TNBC) in the first-line teatment of unresectable locally advanced or metastatic TNBC.
The goal of this research study is to evaluate the safety and feasibility of implanting and retrieving a microdevice that releases microdoses of a specific drug or combination of drugs as a possible tool to evaluate the effectiveness of several cancer drugs against early stage Triple Negative Breast Cancer (TNBC). The name of the intervention involved in this study is: Implantable Microdevice (IMD)
Clinical trials can sometimes favor certain demographic groups. Additionally, there is limited research that delves into the factors that influence participation in clinical trials, both positive and negative. The goal is to identify the obstacles and challenges that prevent participation in Triple Negative Breast Cancer clinical trials, as well as the reasons for withdrawal or discontinuation. The insights gained from this study will ultimately benefit those with Triple Negative Breast Cancer who may be invited to participate in clinical research in the years to come.
