NCT ID: NCT02913729 Recruiting - Breast Cancer Clinical Trials

Pre- Versus Postoperative Accelerated Partial Breast Irradiation

Start date: November 10, 2016
Phase: N/A
Study type: Interventional

Most of the local recurrences (LR) found after breast-conserving therapy are within or close to the tumor bed. This pattern of recurrence was confirmed by studies of breast conserving surgery without adjuvant irradiation and by the update of the NSABP B-06 trial. In the EORTC boost trial, however, 29% of all LR were found outside the area of the original tumor. Still, a recent review of Breast Conserving Therapy (BCT) trials showed that the site of local recurrences after BCT was mostly in the tumor bed, with less than 10% of LR elsewhere in the breast. This led to the concept of partial breast irradiation. With accelerated partial breast irradiation (APBI), a limited volume of breast tissue is irradiated, allowing for a higher dose per fraction compared to whole breast irradiation (WBI), which is favorable considering the low alpha/beta ratio, and thus higher sensitivity to high dose per fraction.

NCT ID: NCT02891681 Completed - Breast Cancer Clinical Trials

Ultrasound and Near Infrared Imaging for Predicting and Monitoring Neoadjuvant Treatment

Start date: November 29, 2016
Phase: N/A
Study type: Interventional

To determine the accuracy of NIR/US assessment of tumor vasculature and oxygen changes in predicting and monitoring early neoadjuvant treatment response compared to pathological response.

NCT ID: NCT02807597 Recruiting - Breast Cancer Clinical Trials

Real-time Intraoperative Breast Cancer Visualization for Margin Assessment

Start date: February 18, 2020
Phase: Phase 1/Phase 2
Study type: Interventional

The investigators' preclinical data have demonstrated the feasibility of fluorescence-guided tumor resection by Cancer Vision Goggles (CVG) with LS301 in animal models. In this study, the investigators will conduct intraoperative imaging procedures that have minimal interference with ongoing surgery. The underlying hypothesis is that the accurate detection of all cancer cells highlighted by LS301 during surgery will reduce the number of breast cancer patients with margin positivity to less than 5%, compared to the current surgical paradigm of greater than 20%. The pilot study will obtain critical data required to address the larger question of surgical margin assessment in a full Phase I clinical trial.

NCT ID: NCT02669914 Terminated - Breast Cancer Clinical Trials

MEDI4736 (Durvalumab) in Patients With Brain Metastasis From Epithelial-derived Tumors

Start date: September 12, 2016
Phase: Phase 2
Study type: Interventional

Brain metastases are the most common intracranial malignancy occurring in 20-40% of all cancers, and the presence of CNS metastases is associated with a poor prognosis. As such, the median overall survival of patients with symptomatic brain lesions is a dismal 2-3 months regardless of tumor type. Because standard chemotherapy largely does not cross the blood brain barrier at a meaningful concentration, standard treatment is limited and usually involves surgical resection and/or stereotactic radiosurgery for isolated lesions and whole brain radiation for multiple lesions. Unfortunately, the median overall survival is only improved by about 6 months with this multimodality approach2, and there is a paucity of second-line therapies to treat recurrence. Furthermore, re-resection and re-radiation are often not feasible options due to concern for increasing complications or neurotoxicity, respectively. Thus, there is a dire clinical need for additional treatment options for this patient population. Checkpoint blockade therapy, in particular PD-1 and PD-L1 inhibition, has recently shown clinical efficacy in multiple types of solid tumors. The investigators propose to study the efficacy of checkpoint blockade therapy in patients with solid tumors and refractory/recurrent brain metastases. The investigators will assess the efficacy of MEDI4736, a novel PD-L1 inhibitory monoclonal antibody, in this study.

NCT ID: NCT02658708 Completed - Breast Cancer Clinical Trials

Bright Light on Fatigue in Women Being Treated for Breast Cancer

Start date: October 12, 2015
Phase: Phase 1
Study type: Interventional

This proposed study will examine feasibility and implement therapeutic bright light that is tailored to the individual's circadian typology to estimate its therapeutic effects on sleep/wake patterns and fatigue in breast cancer patients undergoing chemotherapy.

NCT ID: NCT02595372 Completed - Clinical trials for Cancer of the Breast

Inhibiting Fatty Acid Synthase to Improve Efficacy of Neoadjuvant Chemotherapy

Start date: November 12, 2015
Phase: Phase 2
Study type: Interventional

In preliminary laboratory science studies, the investigators show that proton pump inhibitors (PPIs) effectively inhibit human fatty acid synthase (FASN) and breast cancer cell survival. A preliminary retrospective study shows that PPI usage in breast cancer patients during chemotherapy significantly improved overall survival. The impact was most striking in patients with triple negative breast cancer (TNBC). Thus, PPIs may be repositioned as safe and effective breast cancer drugs to enhance the effect of chemotherapy. Many of the hurdles that slow progress from target, to lead compound, to investigational agent, to standard therapy are not barriers for the PPIs. The PPIs are FDA-approved, chronically used, and well tolerated so the investigators can move quickly from the laboratory to a proof of concept clinical trial. Incorporating the PPIs into standard care will require more than the investigators propose here, but the investigators have already plotted the additional steps needed to truly impact patient care. If successful, the data gathered in this proposal will lend support to and guide development of a definitive randomized trial.

NCT ID: NCT02580448 Completed - Breast Cancer Clinical Trials

CYP17 Lyase and Androgen Receptor Inhibitor Treatment With Seviteronel Trial (INO-VT-464-006; NCT02580448)

Start date: August 2015
Phase: Phase 1/Phase 2
Study type: Interventional

The goal of this clinical study is to determine the safety, pharmacokinetics, pharmacodynamics and efficacy and activity of seviteronel, a lyase-selective inhibitor of CYP17, in patients with advanced breast cancer.

NCT ID: NCT02476786 Recruiting - Breast Cancer Clinical Trials

Endocrine Treatment Alone for Elderly Patients With Estrogen Receptor Positive Operable Breast Cancer and Low Recurrence Score

Start date: January 17, 2017
Phase: Phase 2
Study type: Interventional

Multiple neoadjuvant endocrine trials demonstrate that women with good prognosis tumors can be identified. These trials have also demonstrated that there are not adverse effects on overall outcome if women are treated with neoadjuvant endocrine therapy for several months prior to definitive treatment. A new standard of care needs to be defined for elderly women with good prognosis estrogen receptor (ER)+ tumors, since these women may benefit from endocrine therapy alone to treat their cancer without compromising local and distant control. The investigators hypothesize that endocrine therapy alone provides adequate local and systemic control of breast cancer in a subpopulation of women 70 or older with ER+ breast cancer and low Ki67 scores.

NCT ID: NCT02462200 Terminated - Breast Cancer Clinical Trials

Shave Margins in Breast Conservation Therapy

Start date: June 13, 2016
Phase: Phase 2
Study type: Interventional

The investigators propose a randomized controlled superiority trial of standard breast-conserving surgery (BCS) versus BCS with cavity shave margins (CSM). The main objectives of this trial will be to evaluate prospectively the impact of routine standardized CSM on margin status following primary surgery for early stage breast cancer (Stage 0 - II), on post-operative patient satisfaction and cosmetic outcomes, and on general intraoperative time and operative costs. A parallel group format will be implemented to compare this modified surgical therapy - BCS with CSM - with BCS alone, which is the current standard of care.
