Active clinical trials for "Glioblastoma"

Evaluation of GLR2007 for Advanced Solid Tumors

A multi-centre, open-label, single-arm, dose-finding phase I/II study to evaluate safety, tolerability, dosing schedule, and preliminary efficacy of carrier-added 4-L-[131I]iodo-phenylalanine (131I-IPA), administered as single or repetitive injections in patients with recurrent glioblastoma multiforme (GBM), concomitantly to 2nd line external radiation therapy (XRT) - IPAX-1

In the proposed trial, patients will be administered ribociclib+everolimus prior to surgical resection of their tumor. Recurrent GBM patients will be randomized into one of the three time-interval cohorts for the first two dose levels. In the lead-in dose escalation study, the first six subjects (lead-in) will receive ribociclib 400 mg and everolimus 2.5 mg orally-administered in 5 daily doses with the last dose. If one or less patient experiences DLT among the 6 patients, this regimen with ribociclib 400 mg and everolimus 2.5mg will be considered safe and we will continue with the dose escalation phase of the study up to Level 3. Four dose escalation levels: Level 0: ribociclib 400mg and everolimus 2.5 Level 1: ribociclib 600mg and everolimus 2.5mg Level 2: ribociclib 600mg and everolimus 5mg Level 3: ribociclib 600mg and everolimus 10mg

This research study involves an investigational product: Ad-RTS-hIL-12 given with veledimex for production of human IL-12. IL-12 is a protein that can improve the body's natural response to disease by enhancing the ability of the immune system to kill tumor cells and may interfere with blood flow to the tumor. Nivolumab is an antibody (a kind of human protein) that is being tested to see if it will allow the body's immune system to work against glioblastoma tumors. Opdivo (Nivolumab) is currently FDA approved in the United States for melanoma (a type of skin cancer), non-small cell lung cancer, renal cell cancer (a type of kidney cancer), Hodgkin's lymphoma but is not approved in glioblastoma. Nivolumab may help your immune system detect and attack cancer cells. Ad-RTS-hIL-12 and veledimex will be given in combination with Nivolumab to enhance the IL-12 mediated effect observed to date. The main purpose of this substudy is to evaluate the safety and tolerability of a single tumoral injection of Ad-RTS-hIL-12 given with oral veledimex in combination with nivolumab.

Recombinant humanized monoclonal antibody injection against human vascular endothelial growth factor (bevacizumab) is Avastin produced by Zhengda Tianqing Pharmaceutical Group Co., Ltd Biological similar drugs. Its mechanism is to prevent VEGF from binding to its natural receptor VEGFR, inhibit the proliferation and activation of vascular endothelial cells, and play an anti angiogenesis and anti-tumor role by binding with VEGF. A randomized, double-blind, single dose, parallel comparison of bevacizumab injection and Avastin is planned The phase I clinical study on the similarity of pharmacokinetics and safety of traditional Chinese medicine in healthy male volunteers aims to compare bevacizumab injection with Avastin The similarity of pharmacokinetics, tolerance, safety and immunogenicity.

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 phase I trial evaluating the maximum tolerated dose, safety and efficiency of Mesenchymal stem cells into which the suicide gene, cytosine deaminase (CD), injected into the resection cavity of patients with recurrent glioblastoma.

This trial is set up as a prospective observational cohort study to identify if either biopsy or resection should be the surgical modality of choice in elderly glioblastoma patients with a newly diagnosed tumor. Patients who are considered eligible for GBM resection or biopsy will be included. Through shared-decision making patients and their treating physicians will decide upon resection or biopsy. Written informed consent will be obtained. Participants will be followed for 1 year postoperative to assess potential differences in health-related quality of life and overall survival. Follow-up will consist of health-related quality of life questionaires and neurological assessment at 6 weeks, 3 months, 6 months and 12 months postoperative. Additionally Cognitive and neuro-linguistic tests will be done at 3 months postoperative. These will be compared to results pre-operative. After surgery, patients will receive standard adjuvant treatment with concomitant Temozolomide and radiation therapy, and standard follow-up. Patients in whom the diagnosis GBM is not confirmed in histological analyses will be excluded from the study. Total study duration will be 4 years, of which 3 years will comprise patient inclusion, with a follow-up duration of 1 year.

Background: A glioblastoma is a tumor in the brain. It is treated with surgery, chemotherapy and radiation therapy. However, most people s tumors come back after therapy. When the tumor grows back, surgery or chemotherapy may not be possible or may no longer work. Repeat radiation therapy or re-irradiation, is an option for treating these tumors when they regrow. Objective: To find out the safety and highest tolerated dose of re-irradiation for people who have recurrent glioblastoma. Eligibility: People ages 18 50 who have glioblastoma that has been treated with radiation but has regrown. Design: Participants will be screened with: Medical history Physical exam MRI of the brain: They will lie in a machine that takes pictures of the brain. Participants will have baseline tests before they start therapy. These will include: Blood tests Neuropsychological tests: These test things like memory, attention, and thinking. Quality of life questionnaire Eye and hearing tests Participants will get a CT of the brain prior to radiation start in order to plan the radiation treatment. Once the plan is completed, they will receive radiation once a day Monday Friday for a total of 10 17 treatments. They will lie on their back for about 10 minutes while they get the treatment. Participants will be monitored for side effects. After they finish treatment, participants will have visits 1, 2, and 3 months later. Then they will have them every 2 months for 3 years. These will include: Medical history Physical exam Blood tests MRI of the brain. Quality of life questionnaire Neuropsychological tests (at some visits) After 3 years, participants will be contacted by phone each month.

This research study is studying an immunotherapy as a possible treatment for Glioblastoma.
