Active clinical trials for "Breast Neoplasms"

This is a prospective, registry trial which will enroll women aged 65 and above with early stage, low risk breast cancer who will be treated with partial mastectomy and intraoperative radiation therapy (IORT). The primary aim is to determine the 5-year risk of in-breast tumor recurrence. Secondary aims include identification of acute- and late-toxicity, cosmetic result, disease-free survival and overall survival.

The goal of this observational study is to investigate and validate multi-parametric magnetic resonance imaging (MRI) modalities for assessment of breast cancer response to neoadjuvant chemotherapy in a multi-site and multi-MRI scanner platform setting. This study is conducted at Oregon Health & Science University (OHSU), University of Washington (UW), and University of Iowa (UI) using Siemens, Philips, and General Electric MRI scanners, respectively. MRI is a type of scan that uses a very strong magnet and no radiation to take very detailed pictures of parts of the body. MRI is often used as standard of care to take pictures of breast tumor(s) before and after chemotherapy treatment in order to measure the tumor size changes in response to treatment, and in order to plan for surgery. MRI is used because the images it takes are very clear and the borders of the tumor can be measured very accurately. However the tumor size alone is often not a good early indicator of whether or not the tumor responds to treatment. Tumor size change usually happens late during the period of treatment, and tumor size measured with MRI after treatment can overestimate or underestimate the residual cancer. This makes it difficult to do the right surgical planning. In addition to measuring tumor size, the MRI scans in this research study will also measure changes in tumor blood vessels and the number of cancer cells per unit of tumor volume. The purpose of this study is to see whether MRI measurements of these functional tumor properties provide better early prediction and evaluation of breast cancer response to neoadjuvant chemotherapy than tumor size measurement. This is an observational study because the MRI procedures are not expected to have an effect on health outcomes. Eligible participants on this study are receiving standard of care neoadjuvant treatment for their cancer.

This trial is a multicenter, open-label, non-comparative, phase II, biomarker-driven adjuvant treatment study involving the periodic collection and analysis of blood samples from patients with HR-positive/HER2-negative early-stage BC at higher risk of relapse, who have undergone surgery within the previous five years, with no evidence of locoregional, contralateral, or distant disease. The study design is composed by an initial pre-screening phase, a molecular follow-up phase (ctDNA surveillance phase), and an interventional therapeutic phase (treatment phase). After informed consent is obtained, a total of1,260 eligible patients will enter a ctDNA surveillance in which primary tumor tissue and matched normal blood will be collected from each patient to obtain a patient-specific somatic mutations panel (tumor signature). At the event of ctDNA positivity, patients will be screened to enter the treatment phase of the study. Upon confirmed eligibility, a total of 40 patients will be allocated in one of the following trial's arms adopting a sequential recruitment strategy: Arm A: Control Arm (N=10) Arm B: Experimental Arm with giredestrant (N=10) Arm C: Experimental Arm with giredestrant + abemaciclib (N=10) Arm D: Experimental Arm with giredestrant + inavolisib (N=10) If the strategy of ctDNA monitoring enables physicians to identify patients at high risk of relapse and assess whether treatment at molecular relapse can improve outcome, new cohorts may be added to the study.

This phase I/IIa trial tests the safety, side effects, and best dose of chemokine modulation therapy (CKM) (rintatolimod, celecoxib, and interferon alpha 2b) in combination with pembrolizumab for the treatment of patients with triple negative breast cancer that has spread from where it first started (primary site) to other places in the body (metastatic) or that cannot be removed by surgery (unresectable). CKM drugs such as rintatolimod and interferon alpha 2b work to modify the immune response and tumor-related processes, including tumor cell growth, blood vessel growth, and metastasis. Celecoxib is an anti-inflammatory drug that can cause cell death and may reduce the growth of blood vessels tumors need to grow and spread. Immunotherapy 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. Giving CKM therapy prior to pembrolizumab may direct the immune cells to the cancer cells and maximize the effectiveness of pembrolizumab in patients with metastatic or unresectable triple negative breast cancer.

This study is a Phase 2 open label, single arm, adaptive multi-centre trial. Patients with early stage HER2-positive breast cancer will receive neoadjuvant treatment of trastuzumab deruxtecan (T-DXd) 5.4mg/kg intravenously every three weeks for up to six cycles.

The overarching purpose of this study is to improve precision medicine through more refined therapy selection for breast cancer patients who are candidates for ICI therapy (monoclonal antibodies targeting the programmed death ligand 1 (PD-L1) or programmed cell death protein 1 (PD-1)). The reference standard biomarker for ICI therapy selection is PD-L1 protein expression measured by immunohistochemistry (IHC). Several disadvantages exist with this method, the most important ones being inter- and intralesional as well as spatial heterogeneity in PD-L1 expression, as well as the need for invasive procedures to obtain material for analysis. The study hypothesis is that Positron Emission Tomography combined with Computed Tomography (PET/CT) imaging with a contemporary radiotracer (89Zr-atezolizumab), visualizing PD-L1 expression in the whole body, could be a better predictive biomarker to select which patients benefit from ICI. The use of PET/CT imaging with new radiotracers enables a non-invasive assessment of the presence of the target of treatment in the whole body and provides the possibility to combine functional information with anatomical details.

The neoCARHP study was a randomized, open-label, multicenter, phase III, neoadjuvant trial. This study aimed to compare the efficacy and safety of docetaxel/carboplatin/trastuzumab/pertuzumab (TCHP) with docetaxel/trastuzumab/pertuzumab (THP) neoadjuvant setting for HER2-positive breast cancer. Patients will be randomized at a 1:1 ratio into TCHP or THP, respectively, and will be treated every 3 weeks before surgery.The primary endpoint was the percentage of pCR (ypT0/is, ypN0), which was defined as the absence of any residual invasive cancer in both the breast and axillary lymph nodes.

This is a prospective, randomized, 2-arm, Phrase 2, superiority and multicenter study to compare the efficiency of Anti-HER2 TKI versus Pertuzumab in Combination With Dose-dense Trastuzumab and Taxane in HER2-positive breast cancer patients with active refractory brain metastases.

This is a prospective, single-arm, multi-center observational non-interventional study (NIS) in Germany and Austria.
