Filter by:The purpose of this study is to establish the dose regimen and evaluate the preliminary efficacy and the safety/tolerability of poziotinib in participants with human epidermal growth factor receptor 2 (HER2)-positive metastatic breast cancer who have received at least two prior HER2-directed treatment regimens.
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.
This prospective, non-interventional time and motion study will evaluate the costs of healthcare resource utilization associated with the administration of trastuzumab (Herceptin) SC and IV formulations in HER2-positive EBC. This is a sub-study of the clinical study MO22982 (NCT01401166/PrefHer).
This Phase 1/2 study will evaluate the safety and efficacy of combination treatment with niraparib and pembrolizumab (MK-3475) in patients with advanced or metastatic triple-negative breast cancer or recurrent ovarian cancer. (KEYNOTE-162)
Participants that have breast cancer that has spread to other parts of the body, is positive for a protein called HER2, and has not responded to standard treatment. This research study is a way of gaining new knowledge about the combination of Ribociclib with other drugs as a possible treatment for this diagnosis.
The purpose of the study is the identification and semi-quantification of Ki-67 protein expression level in breast cancer tissues by the GenASIs GoPth system as compared to manual reading of the same slides. The imaging system is intended for diagnostic use as an aid to the pathologist in the detection, counting and classifying ER/PR IHC stained samples
The purpose of the study is the identification and quantification of protein expression level in breast cancer tissues. The imaging system is intended for diagnostic use as an aid to the pathologist in the detection, counting and classifying her2 immunohistochemical (IHC) stained samples.

This is a two part, open label, non-randomized trial of women with a breast cancer diagnosis scheduled for excisional surgery and sentinel lymph node (SLN) evaluation. Part 1 is a two-period, crossover, dose-finding study, which will be performed in 12 healthy female volunteers to determine the optimal dose as well as the safety and tolerability of the tissue-specific, contrast agent Sonazoid (GE Healthcare, Oslo, Norway) for human lymphatic applications. In Part 2 lymphosonographic SLN identification will be compared to that of isotope mapping during surgery on 90 female, breast cancer patients.
- Seventy per cent of breast cancers express estrogen (ER) and progesterone receptors (PR) and respond to endocrine treatment. - Actual therapy targets ER. - There is enough evidence that progestins participate regulating breast cancer growth. - Antiprogestins block cell proliferation and increase apoptosis in breast cancer models which express high levels of PRA. - Antiprogestins have been used to treat breast cancer patients that failed to other treatments; benefits were seen in selected patients. - Mifepristone (MFP) is currently used for medical abortion and for the treatment of Cushing disease. - MFP might exert agonistic effects when PRB isoform is activated by cAMP. This makes mandatory the evaluation of the PR isoform ratio in breast cancer patients in which MFP is a therapeutic possibility. Main Goal To evaluate if therapeutic doses of MFP exert beneficial effects on breast cancers expressing levels of PRA higher than those of PRB, evaluated as an inhibition in proliferation markers and/or an increase in apoptotic markers. - Eligibility - Postmenopausal women (one year after menses stop). - Women with tumors showing ratios of PRA/PRB higher than 1.5 and PR higher than 50%. - Women without previous treatment. - All clinical stages with tumors larger than 1.5 cm. - Patients without autoimmune diseases and/or asthma. - Study design - Open Interventional. - Twenty women will take MFP (200 mg) p.o. once /day during 14 days. As for preliminary studies, to reach this number the investigators will have to evaluate 80-100 patients. - Surgery is performed 14 days after treatment initiation, 24 hs after last dose. - PR isoform ratio will be evaluated by western blots (WB) in one core biopsy. Additional cores will be used for diagnosis, immunohistochemistry (IHC) of PR, Ki-67 and other markers. - At surgery samples will be frozen for molecular studies and fixed and processed for pathological evaluation. - Wilcoxon signed rank test will be used to evaluate differences in biomarker expression between core biopsy and surgical samples of each patient. - Blood will be collected before treatment initiation and prior to final surgery. - Mammographic and echographic studies will be carried out before and after treatment.
