Filter by:This is an open-label, single-arm pilot study evaluating the antitumor activity and safety of niraparib as neoadjuvant therapy in participants with Human epidermal growth factor receptor 2 (HER2)-negative and breast cancer susceptibility gene mutant (BRCAmut) localized breast cancer (primary tumor >=1 centimeters [cm]). Breast magnetic resonance imaging (MRI), breast ultrasound, and tumor core biopsy will be performed at the screening (Days -28 to -1). Participants will receive niraparib (200 milligrams [mg] orally [PO]) treatment daily for 28 days (Cycle 1) and then will undergo breast ultrasound at the end of Cycle 1 on Day 28. Based on breast ultrasound reports, the participants will either discontinue the study (disease progression) or will continue niraparib treatment (complete response [CR], partial response [PR] or stable disease [SD]) for an additional cycle (Cycle 2). A breast MRI and breast ultrasound will be performed at the end of Cycle 2. Approximately 21 participants will be enrolled in this study and the study duration will be approximately 2 years.
Most studies of cancer stem cells (CSC) involve the inoculation of cells from human tumors into immunosuppressed mice, preventing an assessment on the immunologic interactions and effects of CSCs. In this study, the investigators examined the vaccination effects produced by CSC-enriched populations from histologically distinctmurine tumors after their inoculation into different syngeneic immunocompetent hosts. Enriched CSCs were immunogenic and more effective as an antigen source than unselected tumor cells in inducing protective antitumor immunity.Immune sera from CSC-vaccinated hosts contained high levels of IgG which bound to CSCs, resulting in CSC lysis in the presence of complement.CTLs generated from peripheral blood mononuclear cells or splenocytes harvested from CSC-vaccinated hosts were capable of killing CSCs in vitro. Mechanistic investigations established that CSC-primed antibodies and T cells were capable of selective targeting CSCs and conferring antitumor immunity.
The purpose of this study is to support the qualification of a replacement manufacturing site for DOXIL/CAELYX (doxorubicin HCL).
This study will describe the treatment paradigm used over recent years in the clinical management of Human Epidermal Growth Factor Receptor 2 (HER2)+ metastatic breast cancer in Hungary. This information will provide insight into real-world exposure and adherence to anti-HER2 therapy containing regimens, and improve understanding of the reasons for discontinuation of this therapy. This is a retrospective, descriptive, cohort study of approximately 180 female patients diagnosed with HER2-positive metastatic breast cancer in Hungary. Patients diagnosed with, or who progressed to, metastatic disease between 01 September 2009 and 01 September 2010 will be included. All patients will be followed until death, loss to follow-up or the end of the study period (30 September 2012). All data will be collected retrospectively from patient medical records. Descriptive statistics of the demographic and clinical characteristics of HER2+ metastatic breast cancer patients, including sites of metastases, the time from initial breast cancer diagnosis until diagnosis of metastatic disease, and HER2 testing methodology and status of HER2 will be described. Further, descriptive statistics of the proportion of HER2+ metastatic breast cancer patients who received anti-HER2 therapy, the sequencing of different therapies, and the duration of therapies in the metastatic setting will be analysed. Among the subset of women who receive lapatinib plus capecitabine, descriptive statistics of the timing of initiation of lapatinib plus capecitabine in the metastatic treatment pathway, time to treatment discontinuation and time to progression (TTP) on lapatinib plus capecitabine will be calculated. Further, descriptive statistics of the type and duration anti-HER2 therapies used prior to initiation of lapatinib plus capecitabine and, where relevant, after lapatinib+capecitabine will be performed.
The goal of this study is to compare two different types of breast surgery. In the first type, the doctor removes only the tumor. In the second type, the doctor removes the tumor and some of the tissue around the tumor called margins. The amount of breast tissue removed is similar. The removal of the tumor only has up to 40% chance of reoperation because the tumor is too close to the margin. The primary goal of this study is to see if the additional margins can decrease the need to return to the operating room. Both types of surgery are well accepted, and participating in the study would not give you a better chance to cure the cancer. At present, most breast surgeons remove the tumor without the additional margins. For all patients who have this operation, there is a high incidence of return to the operating room for margins re-excision: as many as 40% as patients can have a re-operation. At present, we do not know if taking the additional margins prevents the cancer from returning in the breast or not. If the cancer comes back in your breast, this is a recurrence and your breast will have to be removed (mastectomy).
A study to compare the safety and efficacy of an aromatase inhibitor in combination with lapatinib, trastuzumab or both for the treatment of hormone receptor positive, HER2+ metastatic breast cancer (MBC).
This is an open-label, non-randomized, multi-center study of lapatinib plus paclitaxel to evaluate safety, tolerability and efficacy in Japanese patients with ErbB2 over expressing advanced or metastatic breast cancer. Lapatinib 1500mg/day will be administered in combination with paclitaxel 80mg/m2/week. Lapatinib and paclitaxel will be administered until disease progression or withdrawal from the study due to unacceptable toxicity. The study will proceed in two phases. The first phase (Phase I part) will lead to evaluate safety and tolerability of lapatinib taken together with paclitaxel in the first 6 subjects. Pharmacokinetic profile also will be evaluated as the secondary objects. Then the study will move to the next treatment phase (Phase II part) to evaluate further safety and clinical activity, if no major safety concerns are raised during Phase I part. The primary objective of the study is to evaluate overall survival (OS), and the secondary objectives are Objective tumour response rate (ORR), Duration of response, Time to response, Clinical benefit and Progression-free survival (PFS) in 12 subjects.
The purpose of this study is to determine the efficacy (ability to provide a beneficial treatment of the disease) of pralatrexate for the treatment of female patients with advanced or metastatic breast cancer who have failed prior chemotherapy. Patients will receive vitamin B12 and folic acid supplementation.
This study will assess alternative formulations of lapatinib for relative bioavailability and bioequivalence (BE) with the current commercial formulation (reference). Subjects will be dosed for at least one week (7 days) on each formulation and PK samples will be collected after each lapatinib formulation dosing Period on Period 1 Day 7 and Period 2 Day7 at pre-dose and up to 24 hrs post dose. The study may evaluate up to three alternative test formulations. After subjects complete the PK evaluation at the End of Study Visit, if they are eligible, they will have the option to enter EGF111767, an open-label, Phase Ib continuation study of lapatinib monotherapy or lapatinib in combination with other anti-cancer treatments.
The purpose of this study is to determine whether the treatment of a doxorubicin in combination with cyclophosphamide followed by a combination of pazopanib in combination with paclitaxel prior to surgery results in a pathological complete response in females with breast cancer.
