Filter by:This study is aimed to determine the tolerability of the PF-03084014 plus docetaxel combination in patients with advanced breast cancer. Preliminary information about the efficacy of the combination will also be collected.
This phase II trial studies how well capecitabine, cyclophosphamide, lapatinib ditosylate, and trastuzumab work in treating patients with human epidermal growth factor receptor 2 (HER2)-positive metastatic breast cancer. Drugs used in chemotherapy, such as capecitabine and cyclophosphamide, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving capecitabine and cyclophosphamide daily may kill more tumor cells. Lapatinib ditosylate may stop the growth of tumor cells by blocking some of the enzymes needed for growth. Monoclonal antibodies, such as trastuzumab, can block tumor growth in different ways. Some block the ability of the tumor to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Giving capecitabine, cyclophosphamide, lapatinib ditosylate, and trastuzumab together may be an effective treatment for breast cancer.
This phase II trial studies how well lapatinib ditosylate and radiation therapy work in treating patients with locally advanced or locally recurrent breast cancer. Lapatinib ditosylate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Radiation therapy uses high energy x rays to kill tumor cells. Giving lapatinib ditosylate together with radiation therapy may be an effective treatment for breast cancer.
This is a prospective, single arm phase IIa trial in which patients with early breast cancer will receive pre-operatively two doses of denosumab 120mg subcutaneously one week apart (maximum 12 days) followed by surgery. Tumor, normal breast tissue and blood samples will be collected at baseline and at surgery. Post-operative treatment will be at the discretion of the investigator. Primary objective: to determine if a short course of RANKL inhibition with denosumab can induce a decrease in tumor proliferation rates as determined by Ki67 immunohistochemistry (IHC) in newly diagnosed, early stage breast cancer in pre-menopausal women. Secondary objectives: - To determine the number of absolute Ki67 responders after a short course of denosumab (defined as <2.7% IHC staining in the post treatment tumor biopsy). - To determine the effects of a short course of denosumab on serum C-terminal telopeptide levels (CTX). - To determine the effects of a short course of denosumab on RANK/RANKL gene expression and signaling as assessed by immunohistochemistry (IHC) and RNA sequencing in the tumor. - To determine the effect of a short course of denosumab on tumor apoptosis rates using IHC - To determine the effect of a short course of denosumab on modulating the immature mammary epithelial cell populations in the tumor. - To determine the effect of a short course of denosumab on estrogen signaling pathways in the tumor. - To determine the effect of a short course of denosumab on various immune - To determine effect of safety profile of denosumab
This is a pilot "window of opportunity" clinical study in patients with operable breast cancer investigating use of reparixin as single agent in the time period between clinical diagnosis and surgery. The primary objectives of this study were: 1- to evaluate the effects of orally administered reparixin on CSCs in the primary tumor and the tumoral microenvironment in an early breast cancer population: A. CSC were measured in tissue samples by techniques that could include: ALDEFLUOR assay and assessment of CD44/CD24 by flow cytometry, or examination of RNA transcripts by RT-PCR, aldehyde dehydrogenase-1, CD44/CD24 and epithelial mesenchymal transition markers (Snail, Twist, Notch) by immunohistochemistry (IHC). CSC were defined as ALDEFLUOR positive (ALDH-1+) and/or CD44 high/CD24 low by flow cytometry or RT-PCR and IHC and by the detection of ALDH-1+ cells with or without epithelial mesenchymal transition (EMT) transcription factor in IHC assays. B. Serine-threonine protein kinase (AKT), focal adhesion kinase (FAK), phosphatase and tensin homolog (PTEN) and chemokine receptor-1 (CXCR1) levels were measured in tissue samples by IHC. C. Measurement of markers of inflammation (interleukin-1beta [IL-1β], interleukin-6 [IL-6], interleukin-8 [IL-8], tumor necrosis factor-alpha [TNF-α], granulocyte macrophage colony stimulating factor [GM-CSF], vascular endothelial growth factor [VEGF], basic fibroblast growth factor [b-FGF] and high-sensitivity C-reactive protein [hsCRP]) in plasma, leukocyte subsets (enumerate T subsets, B, and natural killer/natural killer T [NK/NKT] cells) and study polymorphonuclear leukocyte [PMN] biology in peripheral blood samples. D. Measurement of markers of angiogenesis (CD31 staining), tumor-infiltrating leukocytes (CD4, CD8, NK and macrophages), autophagy (P62 and LC3 by IHC), EpCAM and EMT markers (CD326, CD45, Twist1, SNAIL1, SLUG, ZEB1, FOXC2, TG2, Akt2, P13k and CK19 by RT-PCR) and tissue cellularity (residual disease characterization in tumor bed) in tumor tissue samples. 2. To evaluate the safety of oral reparixin administered three times daily (t.i.d.) for 21 consecutive days. The secondary objective was to define the pharmacokinetic (PK) profile of orally administered reparixin.
This protocol will study the impact of cryoablation on immune response in patients diagnosed with invasive breast cancers smaller than 1.5 cm. It will profile the immune response to cryoablation of invasive breast cancers. The intra-tumoral and systemic immune response to cryoablation will be determined and compared to pre-ablated breast cancer specimens and historical control specimens.
The purpose of this study is to determine whether four new alternative imaging methods can be used to follow the response of breast cancer to the treatment patients are being given. These methods produce an image of the inside of the breast so that doctors can better decide whether breast cancer is responding to therapy. An important part of the study is to examine the same person with all methods in order to directly compare results. The four methods are: MRI Elasticity Imaging (abbreviated MRE), Electrical Impedance Spectroscopy (abbreviated EIS), Microwave Imaging and Spectroscopy (abbreviated MIS), Near Infrared Spectroscopy (abbreviated NIR). In addition to the experimental imaging methods, patients may also undergo a contrast-enhanced MRI, and/or additional mammography, which will help researchers compare the experimental methods. These additional examinations are accepted diagnostic procedures; they are not experimental. Some participants will have one or both of these additional examinations if clinically indicated.
There are three major subtypes of breast cancer: 1. Hormone receptor positive (contain cells that express the estrogen receptor or progesterone receptor). 2. Tumors that express the epidermal growth factor receptor gene ( HER-2) 3. Triple negative (cancer cells that lack the hormone receptors and the epidermal growth factor receptor gene HER-2. While effective therapies exist for most cases of breast cancer at first occurrence, many patients eventually exhibit disease that does not respond to all standard breast therapies, particularly in the metastatic setting. There are therapies that are used to treat other types of cancers with genetic mutations that are in the process of being evaluated for use in breast cancer. The current techniques used for detecting mutations in the genes of breast cancer patients, which can be treated with drugs specific for the genetic mutations, are invasive and identifying effective diagnostic non-invasive procedures are the next challenge for physicians. This study will compare the ability to detect genetic mutations samples from non-invasive procedures such as a blood draw, to more invasive procedures such as tissue taken from a biopsy sample. There is also a concern with current techniques used to detect genetic mutations that cells from a single tissue sample may not be representative of the types of cells present in all the tumors in the body and therapies selected using a single tissue sample may not be effective for all of the cancer in the body. This study will use blood drawn from participants prior to any drug therapy and compare the genes from this blood to tissue samples from multiple sites of disease. The study will also compare the genetic profile of the metastatic tumors to the genetic profile of the original breast cancer to determine if there are any changes in the genetics of the tumor cells. The participants that have newly diagnosed metastatic disease will provide tissue from their primary site of disease via an image guided biopsy. These participants will also provide tissue from at least 2 other distant metastatic sites (lung, pleural/peritoneal, liver, brain, or skin). Each biopsy procedure will attempt to obtain 2-3 samples for research purposes. Participants that have locally recurrent disease in the breast will have the tissue from the site of re-occurrence biopsied as well as two distant metastatic sites (lung, pleural/peritoneal, liver, brain, or skin). Participants that have either multi-centric disease or bilateral disease will have all tumors sampled with the intention of providing 2-3 samples/tumor for research purposes. Participants with multi-centric and bilateral disease will also have 2 distant sites of distant disease sampled (lung, pleural/peritoneal, liver, brain, or skin). Prior to any scheduled biopsy procedures all participants will have a blood draw used to examine the genetics of the tumor cells in the blood. The participants will have 8 tubes of blood drawn for the test and then they will proceed onto the tissue sampling portion of the study.
The treatment consists of tumor ablation by Ablathermy Focused Ultrasound (USF), guided by MRI, performed under local anesthesia and sedation.
This study is a multi-institution, Phase Ia/Ib/IIa open-label, dose-finding, safety, pharmacokinetics (PK), and proof-of-concept study of GDC-0810 as a single agent and in combination with palbociclib and/or LHRH agonist. The study is divided into 3 phases: Phase Ia, Phase Ib, and Phase IIa. During Phase Ia (dose escalation phase), GDC-0810 single agent will be administered orally on a continuous daily dosing regimen with a Day -7 lead-in period for single dose PK evaluation prior to the start of daily treatment. The incidence of dose-limiting toxicities (DLTs) will be evaluated from Day -7 through the first cycle (28 days) of treatment (35 days total). Depending on safety and tolerability, participants will be assigned sequentially to escalating doses of GDC-0810 using standard 3 + 3 design. During Phase Ib (dose escalation and expansion phase), participants will receive GDC-0810 with palbociclib and/or LHRH agonist to determine the recommended Phase II dose (RP2D) and assess the safety and tolerability of concomitant administration. During Phase IIa (dose expansion phase), participants previously treated with an aromatase inhibitor (AI) will be treated at the RP2D to further characterize the safety, PK, pharmacodynamics, and anti-tumor activity of GDC-0810.
