Filter by:The primary objective of this study is to ascertain whether there is evidence of longer survival relative to the control arm for three comparisons: 600 mg OGX-427 Arm to control Arm; 1000 mg OGX-427 Arm to control Arm; and pooled 600 mg and 1000 mg OGX-427 Arms to control Arm.
This pilot phase I trial studies how well dasatinib works together with paclitaxel and carboplatin in treating patients with stage III, stage IV, or endometrial cancer that has come back after a period of improvement. Dasatinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as paclitaxel and carboplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving dasatinib together with paclitaxel and carboplatin may kill more tumor cells.
The use of a designed viral vector that can destroy cancer cells while leaving normal cells largely unharmed. The virus also stimulates an immunological response by producing a special factor (GM-CSF) to attract and promote the development of dendritic and T effector cells. It forms the hypothesis that this regimen may be used for people who have failed current forms of treatment and are recommended for cystectomy. It is with hope that this novel therapy will be able to delay or potentially avoid cystectomy for this patient population. Bladder instillation of this agent causes little long lasting side effects and may drastically improve the stimulation of the immune system for local cancer cell death as well as destroying those tumor cells that may have travelled to regional lymph nodes or distant organs.
There is no accepted standard chemotherapy approved for use in the second line for patients with advanced urothelial carcinoma whose cancer has progressed on combination chemotherapy including either cisplatin or carboplatin. The chemotherapy class called taxanes, either as single agents or in combination, have demonstrated modest efficacy in small studies. Cabazitaxel is an agent in the taxane family designed to be active in the setting of acquired multi-drug resistance that arises in some tumors. The objective of this study is to evaluate the safety and efficacy of this agent in patients with urothelial carcinoma refractory compared to combination platinum based chemotherapy.
When the bladder is removed for bladder cancer, pelvic lymph nodes (LN) are also removed. While the anatomic extent of this LN dissection is critical, the investigators often use the number of LN removed as a measure of the extent, which in turn is essential for determining the patient's further treatment and prognosis. The LN count, however, is also dependent on the pathologist's processing of the LN tissue, and the standards for this processing are poorly defined. The goal of this study is to establish a standardized method for processing and analyzing lymph node specimens. The investigators hypothesize that if an organic solvent is used to remove excess fat from the lymph nodes that the investigators will discover more clinically significant nodes in a more reproducible fashion when compared to the current method.
This phase II trial studies how well giving docetaxel and lapatinib ditosylate together as second-line therapy works in treating patients with stage IV bladder cancer that cannot be removed by surgery. Drugs used in chemotherapy, such as docetaxel, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Lapatinib ditosylate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving docetaxel and lapatinib ditosylate together may kill more tumor cells.
Many studies previously showed the significant association between urinary arsenic profiles and urothelial carcinoma (UC) risk and observed the increased UC risk in people with lower plasma folate and higher homocysteine than those with higher plasma folate and lower homocysteine. The investigators would expect to explore the interactions among global DNA methylation, one-carbon metabolic pathway factors, urinary arsenic profiles and UC.
The investigators previously pointed out the significant association between urinary arsenic profiles and urothelial carcinoma (UC) risk through a 12-year follow-up study. Further, the investigators observed the increased UC risk in people with lower plasma folate and higher homocysteine than those with higher plasma folate and lower homocysteine in 2010. S-adenosylmethionine (SAM) is one factor included in one-carbon metabolism pathway and is the main donor of methyl group in cells. The ratio of SAM and its metabolite S-adenosylhomocysteine (SAH) not only reflected the intake level of dietary folate but also demonstrated the extent of global DNA methylation. These factors might play important roles in UC carcinogenesis. The investigators would expect to take three years to explore the interactions among global DNA methylation, one-carbon metabolic pathway factors, urinary arsenic profiles, the polymorphisms and haplotype of Glycine N-methyltransferase (GNMT) and UC. In the first year, the investigators would measure the levels of plasma folate, homocysteine, SAM and SAH and evaluate the associations between these factors and UC risk. In the second year, the investigators would set up the method of immunohistochemistry stain and compare the differences between the global DNA methylation from bladder tissues and blood. In the last year, this investigators would analyze the GNMT gene polymorphism and haplotype variation. At the same time, the investigators would explore the impact of GNMT genetic variation and global DNA methylation on UC risk. Based on the results from our research, the investigators might propose that the decreased ratio of SAM/SAH resulted in UC risk increased. This mechanism might be through the changed levels of urinary arsenic profiles and global DNA methylation.
This study is being conducted to examine survival, safety, and the magnitude of the immune response induced following administration of DN24-02 in subjects with HER2+ urothelial carcinoma.
The primary objectives of this study are (Phase 1) to determine in subjects with unresectable or metastatic bladder cancer who have never had chemotherapy, the dose of lenalidomide that is well-tolerated when given in combination with gemcitabine plus cisplatin and (Phase 2) to study this recommended dose in subjects to evaluate progression-free survival at 1 year. The secondary objectives will be to determine the objective response rate to treatment, and the safety of combination therapy with gemcitabine, cisplatin and lenalidomide as well as to evaluate lenalidomide as maintenance treatment in subjects achieving objective response or stable disease.
