Active clinical trials for "Glioblastoma"

Primary tumor glioblastoma is the most common malignant brain. Standard treatment includes biopsy or excision of the tumor in order to obtain a pathological diagnosis, and tumor mass reduction. After the surgery patients are treated with radiation and Temodal. The most common psychiatric symptom in this patient population is depression, valued at up to approximately 50% in patients with glioma . Depression not only adversely affects the quality of life of patients but also impairs the ability and cognitive function due to the complex clinical course of patients with glioblastoma. There is a tendency to give Diagnosis of depression in this patient population, due to a lack of awareness, knowledge and literature on the subject. This study was designed to prospectively randomized, controlled, double-blind study. This method of recruitment - patients who undergo resection or biopsy of glioblastoma (newly diagnosed glioblastoma), immediately after diagnosis, patients will receive an explanation about the study and sign a consent form will enter research.

This study is investigating the use of a computer algorithm to analyze scans of the brain before surgery to predict how a person's tumor will respond to treatment.

The purpose of this study is to evaluate relationships between multiparametric imaging biomarkers and genetic analysis in glioblastoma patients.

Historically, clinical study participation has been biased toward certain demographics. However, there is a shortage of studies that delve into the underlying factors that influence patient participation, both positively and negatively. Several people will be invited to enroll in this study so that it may collect a variety of data about glioblastoma clinical trial experiences and identify barriers to participation as well as the causes of participants' failure or withdrawal. The data collected from this study will be analyzed and used to improve the experiences of future glioblastoma patients who are recruited for medical trials.

Rationale: Visualization of tumor spread is of crucial importance when treating patients suffering from glioblastoma (GBM) as the success of tumor resection depends strongly on the extent of tumor infiltration. Current MRI protocols, however, cannot visualize the extent the tumor infiltration. The use of non-toxic, non-dangerous ultrasmall superparamagnetic biodegradable iron oxide (USPIO) particles as a very strong blood pool contrast agent could help visualizing this invisible infiltration Objective: To what extent, do GBMs infiltrate healthy brain tissue and can we use ultrasmall superparamagnetic iron oxide particles to visualize co-opting infiltrating tumor cells in an attempt to predict regions of tumor recurrence? Study design: This study concerns a single arm prospective observational study. Study population: Patients diagnosed with suspected glioblastoma. Intervention (if applicable): USPIO neuroimaging Main study parameters/endpoints: The main parameter of this study concerns the feasibility of using of USPIO particles in healthy controls (n=6) and glioblastoma patients (n=15). Nature and extent of the burden and risks associated with participation, benefit and group relatedness: During this study patients will be intravenously injected with low doses of USPIOs. Risks involved with this procedure include: bruising of the skin after venapunction and allergic reaction to USPIO particles. The application of USPIO neuroimaging can improve diagnosis of patients with suspected glioblastoma, provide more information on the pathophysiology of growth of glioblastoma lesiosn, the role of neuro-inflammation in these lesions and maybe predict regions of tumor recurrence after treatment.

A standard treatment for glioblastoma is a combination of radiation and the drug temozolomide. This combination sometimes causing swelling (inflammation) of the brain tissue. When standard monitoring with MRI or CT scans is done within a few months of finishing treatment, it may be hard to tell if the scans are showing post-treatment brain inflammation or tumor growth and worsening of disease. Currently the only way to definitively distinguish inflammation from tumor growth is biopsy. However, biopsy is an invasive procedure that is associated with risks. Having a non-invasive method to distinguish post-treatment inflammation from tumor growth can help improve care for patients with glioma. For the PET scans in this research study, the investigators are using a radioactive substance called FLT (3'-deoxy-3'-[F-18] fluorothymidine), instead of the standard substance FDG (fluorodeoxyglucose). FLT gets absorbed by cancer cells but not by areas of inflammation. Because of that FLT may be better than FDG in differentiating cancer cells from inflammation. An MRI scan will also be done at the same time as each of the 2 FLT-PET scans done for this research study. The two MRI scans performed will also help give more information about the patient's tumor that is not routinely provided with a routine clinical scan, such as blood flow through the tumor or metabolic activity in the tumor. The information from these special MRI scans may provide more information about the blood supply to the tumor and how this changes in response to treatment. In addition, the MRI scans along with the FLT-PET scans may help how to distinguish inflammation due to radiation therapy from tumor growth.

Pear Bio has developed a 3D microtumor assay and computer vision pipeline through which the response of an individual patient's tumor to different anti-cancer regimens can be tested simultaneously ex vivo. This study will recruit patients with primary brain tumors who are due to undergo surgery. Oncologists will be blinded to treatment response on the Pear Bio tool (the assay will be run in parallel with the patient's treatment). The primary objective of this study is to establish the ex vivo model and confirm whether approved therapies exhibit their intended mechanism of action in the model. Secondary objectives include correlating test results to patient outcomes, where available.

It was previously shown that [18F]Fluorodopa (FDOPA) PET imaging results in intended management changes in 41% of brain tumor patients. However, its impact on patient outcome defined as survival, costs, and/or quality of life has not been demonstrated. Regulatory agencies require randomized trials to determine the impact of PET on patient management and outcome. In this study we hypothesize that the addition of FDOPA PET will improve patient outcome by more accurately identifying presence or absence of tumor recurrence than conventional imaging.

Background: The brain is separated from the rest of the blood stream by the blood-brain barrier. This is like a filter that protects the brain. But is also a challenge when medicines need to get into the brain. Researchers want to give the new drug LB100 to people before brain tumor surgery. They will measure how much LB100 is in the blood and how much gets into the brain. This may help with the use of LB100 to treat brain tumors in the future. Objective: To see if LB100 can pass into the brain. Eligibility: People at least 18 years old with a brain tumor that requires surgery Design: Participants will be screened with: Physical exam Medical history Blood tests Neurosurgery evaluation Scans Heart tests Tumor sample. This can be from a previous procedure. Participants will have their brain surgery at the Clinical Center. Participants will get a dose of the study drug through a plastic tube in a vein for 2 hours during surgery. Participants will have blood taken 7 times in the 8 hours after getting the study drug. Tumor samples will be taken during surgery. Participants will have a heart test after getting the study drug. Sticky pads on the skin will measure electrical activity of the heart. Two-three weeks after leaving the hospital, participants will have a follow-up visit. They will have a physical exam and blood tests. One month after surgery, they will be contacted in person or by phone to see how they are doing.

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. ...
