Leptomeningeal metastasis, characterized by tumor cells infiltrating and proliferating in the subarachnoid space, represents a distinct pattern of central nervous system involvement and is a fatal complication of malignant tumors. This phase I/II study is to evaluate the recommended dose, safety, feasibility, and therapeutic response of intrathecal PD-1/VEGF bispecific antibody plus pemetrexed in patients with leptomeningeal metastasis.
This early phase I trial studies brain tumor (glioma) metabolism in response to eflornithine (DFMO) and polyamine transport inhibitor AMXT-1501 dicaprate (AMXT 1501) in patients with diffused or high grade glioma. Brain tumors use and produce certain molecules to survive and grow. DFMO is an irreversible inhibitor of ornithine decarboxylase, the enzyme catalyzing polyamine synthesis. AMXT 1501 is a polyamine transport inhibitor which prevents uptake of polyamines from the extracellular environment. This trial is being done to analyze how DFMO and AMXT 1501 affect brain tumor metabolism based on the molecules in the tumor's fluid.
This phase I trial tests the safety, side effects, and best dose of ex vivo expanded natural killer cells in treating patients with cancerous (malignant) tumors affecting the upper part of the brain (supratentorial) that have come back (recurrent) or that are growing, spreading, or getting worse (progressive). Natural killer (NK) cells are immune cells that recognize and get rid of abnormal cells in the body, including tumor cells and cells infected by viruses. NK cells have been shown to kill different types of cancer, including brain tumors in laboratory settings. Giving NK cells from unrelated donors who are screened for optimal cell qualities and determined to be safe and...
The goal of this clinical trial is to evaluate the safety and tolerability of intratumoral injections of PH-762 in squamous cell carcinoma, melanoma, or Merkel cell carcinomas of the skin, to understand what the body does to the PH-762, and to observe how the tumor responds to the drug. Participants will receive four injections of PH-762 at weekly intervals, into a single tumor, followed by surgical removal of the tumor approximately two weeks later.
Although many intratympanic agents have been attempted, N-Acetylcysteine (NAC) appears to be the most promising and is a powerful, commonly used anti-oxidant. The goal of this prospective phase 2 randomized controlled trial is to determine the optimal dosage and effectiveness of intratympanic NAC injection in reducing hearing loss in head & neck cancer patients receiving cisplatin chemotherapy with curative intent.
This phase I/Ib trial studies the side effects and best dose of intrathecal nivolumab, and how well it works in combination with intravenous nivolumab in treating patients with leptomeningeal disease. Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread.
Anemia is a common complication among cancer patients and is negatively associated with overall prognosis and therapeutic outcomes. The purpose of this study is to see if giving a dose of iron prior to any standard of care chemotherapy treatment will affect the cells that are believed to make treating melanoma harder, making melanoma more responsive to the standard of care immunotherapy.
Intra-operative blood loss of huge meningioma resection patients on average was over 1000ml. Intra-operative massive hemorrhage was associated with longer hospital of stay, higher expense, and higher mortality. Previous studies indicated intra-operative tranexamic acid infusion would decrease blood loss for cardiac, trauma and obstetric procedures. However, limited researches focusing on the effect of tranexamic acid in neurosurgery population, with heterogenous pathologies. The purpose of this study was to investigate the effect of tranexamic acid on intra-operative blood loss in patients undergoing huge meningioma resection.
The MyBrain study investigates the brain function of children, adolescents and young adults during and after chemo treatment for cancer. The tests include 1) cognitive skills such as memory and attention; 2) the brain's electrical activity; 3) and biological markers related to brain function. The aim of the study is to better understand the trajectories of cognitive functioning and measures that have been associated with cognitive impairment in patients treated with chemotherapy.
A medication called temozolomide has been used for many years in the treatment of high-grade gliomas, which are tumours that originate in the brain. While this drug is the normal treatment for high-grade glioma, a number of patients develop a side-effect which results in low levels of some important blood cells, such as platelets or white blood cells. If this side-effect occurs, treatment with temozolomide may have to be stopped or paused, which may affect how well this treatment works. At present, it is unknown why some patients develop this side effect and others do not. It is known that patients with a higher concentration of temozolomide in their blood are at an increased...
