Filter by:This phase II trial studies how well ribociclib and letrozole work in treating patients with estrogen receptor (ER) positive ovarian, fallopian tube, primary peritoneal, or endometrial cancer that has returned (come back) after a period of improvement. Ribociclib may stop the growth of tumor cells by blocking some enzymes needed for cell growth. Cancer cells that are estrogen receptor positive may need estrogen to grow. Letrozole lowers the amount of estrogen made by the body and this may stop the growth of tumor cells that need estrogen to grow. Giving ribociclib together with letrozole may be an effective treatment in patients with ovarian, fallopian tube, primary peritoneal, or endometrial cancer.
This phase II trial studies how well pembrolizumab and doxorubicin hydrochloride works compared to pembrolizumab with anti-estrogen therapy (anastrozole, letrozole, or exemestane) in treating patients with triple-negative or hormone-receptor positive breast cancer that has spread from the primary site (place where it started) to other places in the body. Pembrolizumab is an antibody drug that blocks a molecule called programmed death (PD)-1. PD-1 is a molecule that shuts down the body's immune responses and prevents the immune system from attacking the cancer. Doxorubicin hydrochloride is a drug used in chemotherapy that works to stop the growth of tumor cells by stopping them from dividing and by causing them to die. Anti-estrogen therapy, including anastrozole, letrozole, and exemestane, lowers estrogen levels in the body, which may help treat cancer that is hormone receptor-positive. Giving pembrolizumab together with standard treatment of either doxorubicin hydrochloride (triple-negative cancer) or anti-estrogen therapy (hormone receptor-positive cancer) may be an effective treatment for these types of breast cancer.
The main purpose of this study is to determine the anti-tumor activity of MEDI4736 in combination with tremelimumab in patients with metastatic HER2-negative breast cancer. Both MEDI4736 and tremelimumab are antibodies (proteins used by the immune system to fight infections and cancers). MEDI4736 attaches to a protein in tumors called PD-L1. It may prevent cancer growth by helping certain blood cells of the immune system get rid of the tumor. Tremelimumab stimulates (wakes up) the immune system to attack the tumor by inhibiting a protein molecule called CTLA-4 on immune cells. Combining the actions of these drugs may result in better treatment options for patients with breast cancer.
This phase II trial studies how well accelerated partial breast irradiation (APBI) using high-dose rate (HDR) brachytherapy works in treating patients with breast cancer that has not spread beyond the breast or the axillary lymph nodes (early-stage) after surgery. Radiation therapy uses a type of energy to kill cancer cells and shrink tumors. Brachytherapy is a type of internal radiation therapy that provides radiation inside the breast to any remaining tumor cells next to the space where the tumor was removed, and is given over a shorter amount of time than standard radiation therapy. Giving accelerated partial breast irradiation (APBI) using high-dose rate (HDR) brachytherapy may reduce the overall time that radiation is delivered to the tumor cells.
This partially randomized phase Ib/II trial studies the side effects and best dose of taselisib when given together with enzalutamide and to see how well they work in treating patients with androgen receptor positive triple-negative breast cancer that has spread to other places in the body. Taselisib is a PI3K inhibitor. The PI3K pathway is involved is cancer growth. Androgen may cause the growth of tumor cells. Enzalutamide may stop the growth of tumor cells by blocking the androgen receptor from working. Giving taselisib with enzalutamide may be a better treatment for patients with breast cancer.
This phase I trial studies the side effects and best dose of alisertib when given together with fulvestrant in treating patients with hormone positive breast cancer that has spread to other parts of the body or has spread from where it started to nearby tissue or lymph nodes and cannot be removed by surgery. Alisertib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Estrogen and progesterone are type of hormones made by the body and they can cause the growth of breast cancer cells. Hormone therapy using fulvestrant may fight breast cancer by lowering the amount of estrogen or progesterone the body makes. Giving alisertib together with fulvestrant may be a better treatment for breast cancer.
The purpose of this study is to determine whether lucitanib is safe and effective in the treatment of patients with FGF aberrant metastatic breast cancer, as well as in the treatment of patients with biomarker negative (FGF non-aberrant) metastatic breast cancer.
Background: Several clinical trials are underway to investigate if variable forms of vitamin D (D2 vs. D3) prescribed at different doses (10,000-50,000 IUs/week) can improve the side-effects associated with treatment for estrogen receptor positive (ER+) breast cancer, specifically aromatase inhibitors (AIs.) Presumably for generalizability and potential safety purposes, these trials predominantly exclude women with metastatic breast cancer (MBC); a rapidly expanding sector of the cancer survivor population who experience significant treatment-related side-effects. Evaluation of the safety of vitamin D3 supplementation is crucial since supplementation can lead to high calcium and importantly, in lab studies have shown that vitamin D3 affects a gene that increases estrogen production. To assure that vitamin D3 does not affect the clinical effects of anti-estrogen therapies, the effect of vitamin D3 supplements on estrogen production requires an evaluation that further explores and defines its potential role in symptom management for this population. Objectives: This pilot study will evaluate the feasibility of vitamin D3 supplementation in women with MBC, providing much needed data on the preliminary safety and efficacy of this treatment in this patient population. This study will determine: 1) if weekly supplementation of high dose vitamin D3 increases serum vitamin D levels without adverse effects related to such therapy (primary aim); 2) the effects of vitamin D3 supplementation on symptom management (secondary aim); and 3) if vitamin D3 supplementation is associated with improved inflammation (exploratory aim.) Methods: This is an 8 week "proof of concept" study to monitor laboratory parameters and to assess potential effects on short-term outcomes. Adult, female patients (>=18 years) with ER+ MBC (Stage IV) of any race/ethnicity and a history of vitamin D < 30 mg/dl will be recruited from within and around LUMC. Following current clinical practice guidelines, eligible participants will receive 50,000 IUs of vitamin D3 weekly for 8 weeks. Laboratory values, muscle function and inflammation will be examined pre- and post-supplementation, while symptoms will be assessed at baseline, 4 and 8 weeks post-supplementation. We will assess if increases in vitamin D are associated with clinically significant improvements in symptoms and QOL, and decreased inflammation.
This phase I trial studies the side effects and best dose of everolimus and trastuzumab when given together with letrozole in treating patients with hormone receptor-positive and human epidermal growth factor (EGF) receptor 2 (HER2)-positive breast cancer or other solid tumors that have spread to other places in the body. Everolimus may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Estrogen can cause the growth of breast cancer cells. Hormone therapy using letrozole may fight breast cancer by blocking the use of estrogen by tumor cells. Immunotherapy with monoclonal antibodies, such as trastuzumab, may induce changes in the body's immune system and may interfere with the ability of tumor cells to grow and spread. Giving everolimus, letrozole, and trastuzumab together may be a better treatment for breast cancer and other solid tumors than everolimus alone.
This clinical trial studies use of F-18 16 alpha-fluoroestradiol ([F-18] FES) positron emission tomography (PET)/computed tomography (CT) in measuring tumor hormone receptor expression in patients undergoing endocrine-targeted therapy for newly diagnosed breast cancer or breast cancer that has come back or spread to other places in the body. Comparing results of diagnostic procedures done before, during, and after hormone therapy may help measure a patient's response to treatment.
