Filter by:There is limited knowledge regarding the quality of life and needs of patients with advanced high grade gliomas, especially during the end of life. By doing this research, we are able to assess caregiver and patient symptoms and needs during the end of life phase of patients with brain tumors.
Increasing preclinical and clinical data have shown that myeloid-derived suppressor cells (MDSCs) may represent a significant driver of immunosuppression in glioblastoma (GBM, grade IV astrocytoma) and a potential mechanism of treatment resistance to chemoradiotherapy. Tadalafil, an FDA-approved drug with inexpensive cost and excellent safety profile, has been shown to effectively reduce MDSCs and restore T-cell activation in the peripheral blood and in the tumor microenvironment. The purpose of this study is to investigate the impact of targeting MDSCs in newly diagnosed IDH-wildtype grade III-IV astrocytoma by combining tadalafil with standard of care radiation therapy (RT) and temozolomide (TMZ).
This is a multi-center, open-label, dose escalation study to determine the safety, tolerability, pharmacokinetics, pharmacodynamics, and maximum tolerated dose (MTD) of QBS10072S in patients with advanced or metastatic cancers with high LAT1 expression. The MTD of QBS10072S will be confirmed in patients with relapsed or refractory grade 4 astrocytoma.
The purpose of this pilot study is to determine the safety, tolerability, and the maximum tolerated dose intranasal administration of temozolomide (TMZ) as a single agent in Treatment on the patients with GBM. Intranasal administration is a new method of treating brain tumours for the direct administration of drugs, inhibitors or viruses, with minimal involvement of the BBB. The investigators know the orally prescribed standard chemotherapy temozolomide (TMZ) is widely used to treat glioma tumours. Received evidence of safety and efficacy in a full cycle of preclinical trials (on GLP Standart) and tests of calculated doses of intranasal administration of TMZ in healthy volunteers. Intranasal administration of temozolomide is considered as GBM therapy, which provides direct access to a therapeutic dose of the drug into the brain (to the neoplastic process) with low toxicity
The overall aim of this study is to prospectively characterize social health disparities in a cross-sectional cohort of glioma patients with attention to exploring and thematically categorizing the patient-specific and community-level factors. This will be conducted in two parts.
Hyperfractionated radiation therapy (RT) to 72.0 Gy with BCNU will be compared to conventional radiation therapy to 60.0 Gy with BCNU to determine if hyperfractionated RT can improve the median survival time of adults with supratentorial malignant gliomas.
Background: People cope with cancer in different ways. Mindfulness means focusing on the present moment with an open mind. Researchers want to see if this can help children and young adults with a high-grade high-risk cancer with poor prognosis. Objective: To learn if mindfulness is feasible and acceptable for children and young people with high-grade high-risk cancer with poor prognosis and their caregivers. Eligibility: Children ages 5-24 with a high-grade or high-risk cancer, with a caregiver who agrees to do the study Must have internet access (participants may borrow an iPod for the study) Must speak English Design: All participants will complete questionnaires. These will be about feelings, physical well-being, quality of life, and mindfulness. Researchers will review children's medical records. Participants will be randomly put in the mindfulness group or the standard care group. Participants in the standard care group will: Get general recommendations for coping with cancer Have check-in sessions 1 and 3 weeks after starting. These will last about 10 minutes each. After participants finish the standard care group, they may be able to enroll in the mindfulness group. Participants in the mindfulness group will: Attend an in-person mindfulness training session. The child participant will meet with one research team member for 90 minutes while the parent participant meets with another. Then they will come together for a half hour. Practice mindfulness exercises at least 4 days a week for 8 weeks. Be asked to respond to weekly emails or texts asking about their mindfulness practice Get a mindfulness kit with things to help them do their mindfulness activities at home. Have a 30-minute check-in with their coach 1 and 3 weeks after starting. This can be in person or by video chat. All participants (from both groups) will be asked to answer follow-up questions about 8 and 16 weeks after starting the study. Participants will be paid $20 for each set of questionnaires they complete to thank them for their time. ...
Approximately 90% of children with malignant brain tumors that have recurred or relapsed after receiving conventional therapy will die of disease. Despite this terrible and frustrating outcome, continued treatment of this population remains fundamental to improving cure rates. Studying this relapsed population will help unearth clues to why conventional therapy fails and how cancers continue to resist modern advances. Moreover, improvements in the treatment of this relapsed population will lead to improvements in upfront therapy and reduce the chance of relapse for all. Novel therapy and, more importantly, novel approaches are sorely needed. This trial proposes a new approach that evaluates rational combination therapies of novel agents based on tumor type and molecular characteristics of these diseases. The investigators hypothesize that the use of two predictably active drugs (a doublet) will increase the chance of clinical efficacy. The purpose of this trial is to perform a limited dose escalation study of multiple doublets to evaluate the safety and tolerability of these combinations followed by a small expansion cohort to detect preliminary efficacy. In addition, a more extensive and robust molecular analysis of all the participant samples will be performed as part of the trial such that we can refine the molecular classification and better inform on potential response to therapy. In this manner the tolerability of combinations can be evaluated on a small but relevant population and the chance of detecting antitumor activity is potentially increased. Furthermore, the goal of the complementary molecular characterization will be to eventually match the therapy with better predictive biomarkers. PRIMARY OBJECTIVES: - To determine the safety and tolerability and estimate the maximum tolerated dose/recommended phase 2 dose (MTD/RP2D) of combination treatment by stratum. - To characterize the pharmacokinetics of combination treatment by stratum. SECONDARY OBJECTIVE: - To estimate the rate and duration of objective response and progression free survival (PFS) by stratum.
In this research study, we want to learn about the safety of the study drugs, ribociclib and everolimus, when given together at different doses after radiation therapy. We also want to learn about the effects, if any, these drugs have on children and young adults with brain tumors. We are asking people to be in this research study who have been diagnosed with a high grade glioma, their tumor has been screened for the Rb1 protein, and they have recently finished radiation therapy. If a patient has DIPG or a Bi-thalamic high grade glioma, they do not need to have the tumor tissue screened for the Rb1 protein, but do need to have finished radiation therapy. Tumor cells grow and divide quickly. In normal cells, there are proteins that control how fast cells grow but in cancer cells these proteins no longer work correctly making tumor cells grow quickly. Both study drugs work in different ways to slow down the growth of tumor cells. The researchers think that if the study drugs are given together soon after radiation therapy, it may help improve the effect of the radiation in stopping or slowing down tumor growth. The study drugs, ribociclib and everolimus, have been approved by the United States Food and Drug Administration (FDA). Ribociclib is approved to treat adults with breast cancer and everolimus is approved for use in adults and children who have other types of cancers. The combination of ribociclib and everolimus has not been tested in children or in people with brain tumors and is considered investigational. The goals of this study are: - Find the safest dose of ribociclib and everolimus that can be given together after radiation. - Learn the side effects (both good and bad) the study drugs have on the body and tumor. - Measure the levels of study drug in the blood over time. - Study the changes in the endocrine system that may be caused by the tumor, surgery or radiation.
This is a three parallel cohort, open-labeled, non-randomized, multicenter study. All three cohorts will enroll independently.
