Filter by:Background: - IMC-A12 is an experimental substance designed to inhibit a protein called Type I Insulin-Like Growth Factor Receptor (IGF-1R), which can be found on cancer cells and can promote cancer growth. Temsirolimus is a drug that the U.S. Food and Drug Administration has approved to treat advanced renal cell carcinoma in adults. Researchers do not know if the combination of IMC-A12 and temsirolimus will work in children, but want to determine whether these two drugs may be an effective treatment for recurrent tumors. Objectives: - To determine the safety and effectiveness of IMC-A12 and temsirolimus in treating children and adolescents with solid tumors. - To determine possible side effects of the combination of IMC-A12 and temsirolimus. Eligibility: - Children and adolescents between 12 months and 21 years of age who have solid tumors that have not responded to or have relapsed after standard treatment. Design: - Participants will be screened with a medical history, physical examination, and imaging studies. - Participants will receive IMC-A12 and temsirolimus in 28-day cycles of treatment. IMC-A12 will be given as an infusion over 1 hour, once a week, for 4 weeks. Temsirolimus will also be given after IMC-A12 over 30 minutes, once a week, for 4 weeks. - Participants may continue to receive IMC-A12 and temsirolimus for up to 2 years unless serious side effects develop or the treatment stops being effective. - Participants will have additional physical exams, blood and urine tests, and imaging studies regularly during each treatment cycle. - Participants will be followed at regular intervals after the end of the study to collect tumor response and progression data....
Background: - Children with brain tumors often have magnetic resonance imaging (MRI) scans to see if the tumor has responded to therapy or to see if the tumor has grown. Sometimes, it is difficult to tell if the scan is abnormal because of tumor size or shape, swelling, scar tissue, or dead tissue. Because brain tumor biopsies require surgery, researchers are looking for more noninvasive ways of evaluating brain tumors. - Positron emission tomography (PET) scans use a radioactive sugar known as 18F-FDG to try to determine if a tumor is active or not. Active tumors generally take up more sugar than the surrounding tissue, but because normal brain tissue uses the same sugar as brain tumors, it is then difficult to tell if tumor tissue is taking up sugar or not. A different radioactive agent, 18F-FLT, is now being studied in some adults with different kinds of tumors. Researchers are interested in determining whether it is possible to use this agent as a marker of tumor activity in children. Objectives: - To determine the safety and effectiveness of 18F-FLT for pediatric glioma scans. - To compare the results of 18F-FLT studies with studies using the radioactive agents 18F-FDG and 1H-MRSI. Eligibility: - Children less than 18 years of age who are having radiation therapy to treat malignant gliomas. Design: - Participants will have scanning tests before radiation therapy, 1 to 3 weeks after radiation therapy, and if researchers suspect that the tumor is growing. - This study will involve three separate imaging tests (1H-MRSI, 18F-FDG PET, and 18F-FLT PET). - Proton spectroscopy (1H-MRSI) is a procedure that is similar to MRI and is performed in the same scanner as an MRI. Because this scan is long (2-3 hours), most children will receive medications from an anesthesiologist so that they can sleep through the procedure. - Within 2 weeks of the 1H-MRSI scan, participants will have the PET scans with both the standard contrast agent (18F-FDG) and the experimental agent (18F-FLT). These scans will last approximately 1 hour each.
Objectives: This study is looking at the level of vascular endothelial growth factor (VEGF) circulating in the blood stream of patients diagnosed with either a meningioma or a glioma. The questions that will be addressed include: 1. Can VEGF level alert us to tumor progression or recurrence before MRI changes occur? 2. Is the VEGF level an indicator of the response to treatment? 3. Does the VEGF level correlate with tumor histology and behavior? 4. Is there a relationship between VEGF level and outcome?
The primary objective of this study is to determine the maximum tolerated dose (MTD) and dose limiting toxicity (DLT) of dasatinib when combined with protracted, daily temozolomide (TMZ). Secondary objectives are: To further evaluate the safety and tolerability of dasatinib plus protracted, daily TMZ; 2. To evaluate the pharmacokinetics of dasatinib when administered with protracted, daily TMZ among recurrent malignant glioma patients who are on and not on CYP-3A enzyme inducing anti-epileptic drugs (EIAEDs); 3. To evaluate for anti-tumor activity with this regimen in this patient population.
A Pilot Study Evaluating Minimized Time to Beam Hypofractionated IMRT with PET Assisted Target Definition in Patients with High Grade Gliomas The aim of this pilot project is to explore the feasibility of combining a simple conformal plan (Phase I) with an IMRT treatment approach (Phase II) for high grade glioma patients with the aim of starting the RT as soon as possible following the patient's first outpatient visit (thus, minimized 'time to beam'). It is hoped that the rapid treatment start with the initial 3D CRT plan will lessen clinical deterioration due to the growth of these aggressive tumours. The use of Linac-based IMRT in Phase II of the patient's treatment plan will maintain the benefit of the sophistication of IMRT. Using novel PET imaging we also hope to better characterize regions of glioma cells thus producing more optimized planning target volumes (PTVs) for each patient and decreasing the volume of normal brain irradiated with the aim of minimizing radiation toxicities. Hopefully this planning and treatment approach will provide an improvement in the quality of life and outcome for high grade glioma patients.
IL13-PE38QQR is an oncology drug product consisting of IL13 (interleukin-13) and PE38QQR (a bacteria toxin). IL3-PE38QQR is a protein that exhibits cell killing activity against a variety of IL13-receptor positive tumor cell lines indicating that it may show a therapeutic benefit. In reciprocal competition experiments, the interaction between IL13-PE38QQR and the IL13 receptors was shown to be highly specific for human glioma cells.
