Active clinical trials for "Breast Neoplasms"

This phase III trial compares the effect of adding whole brain radiotherapy with hippocampal avoidance and memantine to stereotactic radiosurgery versus stereotactic radiosurgery alone in treating patients with cancer that has spread to the brain and come back in other areas of the brain after earlier stereotactic radiosurgery. Hippocampus avoidance during whole-brain radiation therapy decreases the amount of radiation that is delivered to the hippocampus, which is a brain structure that is important for memory. The medicine memantine is also often given with whole brain radiation therapy because it may decrease the risk of side effects of radiation on thinking and memory. Stereotactic radiosurgery delivers a high dose of radiation only to the small areas of cancer in the brain and avoids the surrounding normal brain tissue. Adding whole brain radiotherapy with hippocampal avoidance and memantine to stereotactic radiosurgery may be effective in shrinking or stabilizing cancer that has spread to the brain and returned in other areas of the brain after receiving stereotactic radiosurgery.

The effect of internal mammary irradiation (IMI) added to whole-breast or thoracic-wall irradiation plus supraclavicular (SVC) irradiation after surgery on survival among women with early-stage intermediate risk (N1) breast cancer remains debated. The present study aimed to identified patient could be omitted from internal mammary lymph node irradiation by using a clinical-genomic model.

This is a Phase III, two-arm, randomized, double-blind placebo-controlled study in participants with HER2-positive primary breast cancer who have received preoperative chemotherapy and HER2-directed therapy, including trastuzumab followed by surgery, with a finding of residual invasive disease in the breast and/or axillary lymph nodes.

The objectives of this study are: 1) To design and implement the PaiNEd system for the evaluation and treatment based on Pain Neuroscience Education (PNE) in cancer survivors with sequelae derived from medical treatments; 2) Study the effectiveness of the PaiNEd system integrated in a multimodal physical recovery program compared to traditional biomedical information. This project aims to first carry out the design and implementation of an e-health system for the evaluation and treatment of pain. A randomized controlled experimental study will be carried out in which 72 breast cancer survivors will be recruited and randomly assigned to three study groups.

Detection of molecular relapse with circulating tumour DNA analysis can identify which patients with ER positive breast cancer are relapsing on adjuvant endocrine therapy. This trial will aim to demonstrate that palbociclib and fulvestrant, can defer or prevent relapse in patients with ctDNA detected molecular relapse. The TRAK-ER trial will have two phases, a ctDNA surveillance phase and a randomised therapy trial in patients with positive ctDNA. The TRAK-ER trial will establish a ctDNA screening programme for patients with ER positive breast cancer receiving adjuvant endocrine therapy with at least a further three years of standard adjuvant endocrine therapy planned. Patients recruited into the TRAK-ER study will have high-risk clinical features to identify patients at higher risk of future relapse. ctDNA assays will be used to identify which people are at very high risk of relapse (i.e. those with a positive ctDNA result), and randomise this high risk population between standard endocrine therapy versus palbociclib plus fulvestrant for up to two years.

This is a phase 3, single arm, open-label study evaluating the effectiveness of TOL2506 to suppress ovarian function in premenopausal women with HR+, HER2-negative breast cancer. The study will also aim to assess the safety of TOL2506 in men with HR+, HER2-negative breast cancer. The Screening Period will be conducted in two parts: 1) an abbreviated, initial screening where premenopausal status will be determined prior to neoadjuvant or adjuvant chemotherapy (if planned) and 2) the full screening assessment conducted after neoadjuvant or adjuvant chemotherapy (or for subjects who enter the study without having received chemotherapy). Following the Screening Period, eligible subjects will enter into the 48 week Treatment Period in 1 of 2 groups: those who will receive tamoxifen concurrently with TOL2506 or those who will initiate therapy with an AI (letrozole, anastrozole, or exemestane) beginning 6 weeks after the first administration of TOL2506, upon confirmation that estradiol (E2) levels of < 20 pg/mL (testosterone levels < 50 ng/dL in males) have been achieved. After Week 12, subjects will be allowed to switch from receiving an AI to receiving tamoxifen or from tamoxifen to AI at the discretion of the Investigator. However, a switch is not permitted 28 days prior to a dosing visit (eg, Week 24, 36, and 48 where a pre-dose blood sample for PK and PD analysis will be drawn). At the end of the Treatment Period, upon completion of the End of Study Visit (Visit 9, Week 48) subjects may be eligible to participate in a Safety Extension Study under a separate Protocol.

Antibody-dependent cell-mediated cytotoxicity (ADCC) is one of the important mechanisms for suppressing tumors of Trastuzumab. Pre-clinical data suggest that the ADCC effect of Inetetamab, an anti-HER2 monoclonal antibody with a modified Fc segment, is 1.11 times that of trastuzumab. Previous studies indicated that enhanced ADCC effects can be transformed into clinical benefits. Immune induction through cyclophosphamide metronomic chemotherapy may further enhance the ADCC effect of anti-HER2 monoclonal antibodies. Therefore, we conducted this study to explore the efficacy and the safety of Inetetamab combined with cyclophosphamide metronomic chemotherapy and aromatase inhibitors(AI) in the treatment of metastatic HER2-positive and HR-positive breast cancer patients and to explore the possible mechanisms.

The primary objectives of this study are as follows: Phase 1 (sequential dose-escalation): to evaluate the safety and tolerability of sacituzumab govitecan-hziy (SG) as a single agent and to determine the recommended Phase 2 dose (RP2D) of SG in Japanese participants with advance solid tumors. Phase 2: Evaluate the safety and efficacy of SG in Japanese participants with metastatic triple-negative breast cancer (mTNBC), hormone receptor-positive (HR+)/human epidermal growth factor receptor 2-negative (HER2-) metastatic breast cancer (mBC), and metastatic urothelial cancer (mUC).

This is the first prospective randomized and controlled study on the efficacy and safety of TiLOOP® Bra mesh in patients with expander-implant breast reconstruction. The investigators hypothesize that incoporating TiLOOP Bra mesh with tissue expanders will reduce the rates of capsular contraction, improve the efficiency of expansion and provide better aesthetic result.

Breast cancer is the most common cancer in the United States however, little is known about how diet can affect cancer treatment. Pre-clinical murine studies report intermittent fasting increases effectiveness of chemotherapy and decreases treatment related adverse events. The proposed research will demonstrate that time restricted eating, a form of intermittent fasting, will improve treatment related outcomes, patient related outcomes, and limit treatment related weight gain and fat mass accretion.Time restricted eating combined with a mediterranean diet will also be feasible and improve cardiometabolic risk more than TRE alone or standard care.
