Filter by:This study is for patients that have brain cancer. The body has different ways of fighting infection and disease. No single way seems perfect for fighting cancers. This research study combines two different ways of fighting cancer: antibodies and T cells. Antibodies are types of proteins that protect the body from infectious diseases and possibly cancer. T cells, also called T lymphocytes, are special infection-fighting immune cells present in the blood that can kill other cells, including cells infected with viruses and tumor cells. Both antibodies and T cells have been used to treat patients with cancers. They have shown promise, but have not been strong enough to cure most patients. The antibody used in this study is called anti-HER2 (Human Epidermal Growth Factor Receptor 2). This antibody sticks to tumor cells because of a substance on the outside of these cells called HER2. Many types of brain tumors are positive for HER2 . HER2 antibodies have been used to treat people with HER2-positive cancers. For this study, the HER2 antibody has been changed so that instead of floating free in the blood it is now attached to T cells. When an antibody is joined to a T cell in this way it is called a chimeric antigen receptor (CAR). These CAR-T cells seem to be able to kill tumors like the one these patients have, but they don't last very long and so their chances of fighting the cancer are limited. Therefore, developing ways to prolong the life of these T cells should help them fight cancer. These HER2-CAR T cells are an investigational product not approved by the Food and Drug Administration. The purpose of this study is to find the largest safe dose of HER2-CAR T cells, to learn what the side effects are, and to see whether this experimental intervention might help patients with brain tumors who volunteer to test this new agent.
This phase Ib combination study is being conducted to assess the safety and tolerability of radium Ra 223 dichloride in combination with paclitaxel in cancer subjects with bone lesions with special focus on Grade 3/4 incidence of neutro- and/or thrombocytopenia and exploration of the mode of interaction (i.e. additive or synergistic interaction) between the selected chemotherapy and radium Ra 223 dichloride with regard to myelosuppression.
Participants in this research study have tumors that express somatostatin receptors such as neuroendocrine tumors, medulloblastoma, meningioma, and neuroblastoma. Approximately 64 people will participate in this study conducted at the University of Iowa.
Participants in this study have been diagnosed with a tumor such as a carcinoid, neuroendocrine tumor, neuroblastoma, Ewing's sarcoma, or brain tumor that has cells which carry somatostatin receptors. The purpose of this research study is to see if the tumor can be identified using a special procedure called a positron emission tomography (PET) scan and how the results of this imaging procedure will change the management of the tumor.
The FDA and Health Canada have approved regorafenib at a daily dose of 160mg for the treatment of metastatic colorectal cancer and gastrointestinal stromal cancer; however, the 160 mg dose is not well tolerated by patients, especially women. The purpose of this study is to determine if lean body mass and acidity in the intestinal tract impact how regorafenib is absorbed into the bloodstream and then broken down and removed from the body. This may explain the side effects experienced at the 160 mg dose, especially by women, and inform regorafenib dosing in the future.
This study will follow-up immune cell populations, secreted factors and released nanovesicles in the blood before, during and after high dose radiation therapy which should give new information of the efficacy of the hypofractionated high dose radiation therapy and a rationale for adjuvant immunotherapy.
This clinical trial is designed to compare the effect of single postoperative intravesical chemotherapy instillation versus maintenance therapy on reducing bladder cancer recurrence after surgery for UTUC.
The purpose of this study is to evaluate the safety, pharmacokinetics, anti-tumor activity, and identify a tolerable dose of AMG 228 in subjects with advanced solid tumors.
The purposes of this study are - to test the hypothesis that elimination or reduction of dietary animal proteins leads to an improved prognosis in tumor patients - to estimate the effect size and thus to enable sample size calculations for further studies - to test the feasibility and tolerance of different diets, especially a vegan diet, in cancer patients and to proof that a vegan diet does not lead to a deterioration of health, tumor progression or to malnutrition - to test the online platform as a study platform - to test validity of self reported and online generated data
It is a cross-sectional study examining a random sample of in- and out-patients, with proven malignant disease receiving chemotherapy, over a period of 6 months from the start of the study who visit the Oncology department, Ain Shams University Teaching Hospitals. The effect of some risk factors on the prescribing error will be studied; these risk factors include the following: Tumor type ,Cancer stage ,type of comorbid illness ,type of medication , type of anti-cancer treatment , number of abnormal lab data ,type of abnormal lab data , the number of drugs in the treatment regimen , the number of side effects after chemotherapy administration, the age of patient ,the dosing frequency of anticancer ,the route of administration . Summary statistics are performed to describe patient characteristics , frequency, types and classification of medication error; and frequency with which Medication errors occur. Logistic regression will be applied to the collected data to perform a predictive relation between the risk factors which may be (categorical, continuous, or discrete) and the prescribing errors which are (categorical).
