Active clinical trials for "Breast Neoplasms"

RATIONALE: Radiotherapy (RT) can be indicated to patients submitted to breast-conserving surgery, but, despite the benefits, adjuvant RT can cause contracture generated by tissue fibrosis in patients with immediate prosthetic reconstruction, which could cause prosthesis loss. The biological explanation of this outcome is not fully understood, but recent advances in the analysis of patient-derived blood can contribute to establishing a connection of molecular alterations related to this clinical outcome. There is not a consensus about using hypofractionated RT schemes for patients with BCS and breast reconstruction since no studies had investigated the reasons why some patients lose the prosthesis. PURPOSE: This study will evaluate G3 toxicity rate in breast cancer patients with immediate prosthetic reconstruction, submitted to hypofractionated radiotherapy, analyzing capsular contracture, leakage, infection, and bad positioning in order to demonstrate the noninferiority of Hypo-RT with the conventional RT. Additionally, the molecular profile of blood samples will be investigated in order to find biomarkers related to inflammations processes and response to treatment.

This is a multicenter, open-label, single-arm, multicohort, two-stage optimal Simon's design, phase II clinical trial that is designed to improve the tolerance of sacituzumab govitecan in patients with unresectable locally advanced or metastatic triple negative breast cancer (TNBC), refractory to at least one, and no more than two, prior standard of care chemotherapy regimens in this setting that is not amenable to resection with curative intent. The goal of this study is to evaluate the safety of sacituzumab govitecan in combination with loperamide and G-CSF in pretreated patients with unresectable locally advanced or metastatic TNBC.

This study aims at assessing the vitamin Dstatus in breast cancer patients who receive letrozole for more than two months and to evaluate effects of vitamin D3 and calcium supplementation on arthalgia caused by letrozole on these patients.

This study will evaluate the efficacy and safety of ceralasertib followed by durvalumab plus nab-paclitaxel in 37 patients with TNBC, whose tumor relapsed following treatment with curative intent for early disease, which must have included immunotherapy and chemotherapy as part of the radical locoregional therapy (either adjuvant, neoadjuvant or both).

Breast cancer (BC) is the most common neoplasm in the world. In Spain, one in 8 women is diagnosed with BC. The human epidermal growth factor receptor 2 (HER2)-positive BC subtype (that represents around 20% of all BC) was associated with poor prognosis however, new therapeutic advances have significantly increased the cure rate of patients in early stages. In the metastatic setting, anti-HER2 targeted therapies have significantly improved overall survival (OS) with good quality of life, however there is still a substantial group of patients who die, and therefore additional drugs need to be investigated. Trastuzumab, an anti HER2 antibody has demonstrated, in combination with chemotherapy, an improvement of OS in early and metastatic stages. Tucatinib is an oral selective inhibitor of the HER2 receptor tyrosine kinase subunit. Its high affinity for this subunit causes fewer toxicities, such as rash and diarrhea, which are common with other anti-HER tyrosine kinase inhibitors (TKIs). Vinorelbine has been evaluated previously in combination with trastuzumab showing interesting results. This is a single country, multicenter, single arm phase II clinical trial with a safety run-in phase, to study the efficacy, safety and tolerability of the administration of tucatinib in combination with trastuzumab and vinorelbine in HER2-positive non-resectable locally advanced or metastatic breast cancer (MBC) with measurable disease.

This research study will evaluate how well brain metastases associated with HER-2 positive breast cancer can be controlled using a type of radiation known as stereotactic radiosurgery (SRS) when combined with three therapeutic agents, tucatinib, capecitabine, and trastuzumab. The combined use of SRS with the three drugs is considered investigational.

This research study is looking to see how well male breast cancer responds to preoperative treatment with endocrine therapy and which endocrine therapy regimen is the most effective treatment for male breast cancer. The drugs used in this study are: Tamoxifen Anastrozole Degarelix Abemaciclib

A phase 1b study to assess the combination of ARV-471 and everolimus in participants with advanced or metastatic ER+/HER2- breast cancer.

This is a Phase 3, open-label, randomized, clinical trial evaluating the efficacy and safety of gedatolisib plus fulvestrant with or without palbociclib for the treatment of patients with locally advanced or metastatic HR+/HER2- breast cancer following progression on or after CDK4/6 and aromatase inhibitor therapy.

In preclinical research, short-term fasting (STF) protects tumor-bearing mice against the toxic effects of chemotherapy, improves the CD8+ effector T-cell intratumor infiltration, while enhancing the chemotherapy efficacy. Short-term use of a "fasting-mimicking diet" (FMD) caused a major increase in the efficacy of cancer treatment in mice comparable to STF. In humans, the investigators recently performed a multicenter randomized phase II trial showing that patients with Human Epidermal growth factor Receptor 2 (HER2) negative breast cancer treated with neoadjuvant chemotherapy and FMD displayed a better radiological response and a better pathological response (90-100% vs <90% tumor cell reduction) than patients treated with chemotherapy without FMD (de Groot, Nat Commun 2020; NCT02126449). Therefore these findings will be validated in a phase 3 trial with the underlying hypothesis that FMD during neoadjuvant chemotherapy for breast cancer improves clinical outcomes, potentially due to improved local immunity.
