Filter by:The aim of this protocol is to refine the accuracy of proton beam therapy (PT) by the use of dual energy computed tomography (DECT), in conjunction with novel iterative image reconstruction algorithms, to more precisely determine the tissue properties through which the proton beam path travels.
This study aims to evaluate anatomical and functional changes during RT for patients receiving fractionated RT for brain tumors. Anatomical changes during RT will be registered and analyzed and if needed the radiotherapy plan will be modified for the individual patient. This means that the "to be irradiated volume" will be modified according to the shape changes of the tumor. The functional MRI sequences will be used to evaluate what parameters, and at which time point, are important for radiotherapy outcome.
This is a Phase 1 study of E6201 plus dabrafenib for the treatment of CNS metastases in BRAF V600-mutated metastatic melanoma. A total of up to N=28-34 subjects with melanoma metastasized to the CNS will be included.
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. The main purpose of this study is to evaluate the safety and tolerability of a single tumor injection of Ad-RTS-hIL-12 given with oral veledimex in the pediatric population.
The purpose of this study is to evaluate the effect of the ketogenic diet on tumor size and quality of life in pediatric patients with malignant or recurrent/refractory brain tumors.
This pilot phase II trial study evaluates the usefulness of the ferumoxytol steady state magnetic resonance imaging (MRI) technique for response assessment after pembrolizumab and radiation therapy in non-small cell lung cancer that has spread to the brain (brain metastases). The interactions of monoclonal antibodies such as pembrolizumab, and the body's immune system may result in an anti-tumor effect. However, it may also increase inflammation around the tumor which cannot be differentiated from true tumor growth on standard MRI. This study evaluates ferumoxytol as an MRI contrast agent to differentiate this treatment related inflammation from true tumor growth.
Background: Sometimes breast cancer spreads (metastasizes) to the brain. Researchers want to study new treatments for brain metastases. The drug Temozolomide is approved to treat brain tumors. Researchers want to see if combining it with the drug trastuzumab emtansine (T-DMI) prevents the formation of new metastases in the brain. Objective: To study if Temozolomide with T-DM1 lowers the chance of having new metastases in the brain. Eligibility: Adults at least 18 years old with a human epidermal growth factor receptor 2 (HER2)-positive breast cancer that has spread to the brain and was recently treated with stereotactic radiation or surgery. Design: Participants will be screened with - Medical history - Physical exam - Heart tests - A scan (computed tomography (CT) that makes a picture of the body using a small amount of radiation - A scan (magnetic resonance imaging (MRI) that uses a magnetic field to make an image of the brain - Blood tests. - Pregnancy test. The study will be done in 3-week cycles. All participants will get T-DM1 on Day 1 of every cycle through a small plastic tube inserted in an arm vein. Some participants will also take Temozolomide capsules by mouth every day. Participants will keep a medication diary. During the study, participants will also: - Repeat most of the screening tests. - Answer questions about their general well-being and functioning. Participants will have lumbar puncture at least 2 times. A needle is inserted into the spinal canal low in the back and cerebrospinal fluid is collected. This will be done with local anesthesia and with the help of images. Participants will be asked to provide tumor samples when available. Participants will have a follow-up visit about 1 month after stopping the study drug. They will be contacted by telephone or email every 3 months after that.
Tools for improving brain tumor surgery, in particular for gliomas, are increasing. There seems to be an agreement that achieving extensive resections, when done safely without jeopardizing neurological function, improves survival. Ultrasound is currently used as a tool for providing 2D or 3D images for tumor localization and resection control. For the use in resection control the resection cavity is filled with saline to provide acoustic coupling between the ultrasound transducer and tissue. However, attenuation of acoustic waves is very low in saline compared to the brain and this difference in attenuation is the cause of artifacts that may severely degrade the ultrasound images. Such artifacts are seen as high-intensity signal at the resection cavity wall and beyond. The artificial signal enhancement can potentially mask small tumor remnants and is generally making the interpretation of images more difficult. This research group has developed an acoustic coupling fluid intended for use in the resection cavity instead of saline. Tests in laboratory measurements have shown that the fluid reduces artifacts and has the potential to enhance ultrasound image quality in brain tumor surgery. Three different concentrations of the acoustic coupling fluid have been tested in a phase 1 study that included 15 patients with glioblastoma. The concentration that provided the optimal ultrasound images, from qualitative and quantitative inspection, is used in the current phase II study. This study is a randomized controlled trial aiming to include 82 patients with glial brain tumours. Its purpose is to test the fluid during surgery of glial brain tumours to further investigate safety and efficacy.
This is an adaptive design, randomized controlled, Phase 3 clinical trial in patients with glioblastoma multiforme (GBM) or gliosarcoma (GS), previously treated with surgery (if appropriate), standard of care chemo-radiation with temozolomide, +/- adjuvant temozolomide, and bevacizumab and now has progressive disease during or after bevacizumab. A total of up to 180 eligible patients with recurrent/progressive GBM or GS will be randomized to receive either the investigational drug (VAL-083) or "Investigator's choice of salvage therapy" as a contemporaneous control, in a 2:1 fashion. Up to 120 eligible patients will be randomized to receive VAL-083 at 40 mg/m2 IV on days 1, 2, and 3 of a 21-day treatment-cycle, for up to 12, 21-day treatment cycles or until they fulfill one of the criteria for study discontinuation. Up to 60 patients will be randomized to receive "Investigator's choice of salvage therapy", limited to temozolomide, lomustine, or carboplatin, until they fulfill one of the criteria for study discontinuation. The dose level for Investigator's choice salvage therapy (temozolomide, lomustine, or carboplatin), will be in accordance with the product label or institutional guidelines. In both study arms, interval medical histories, targeted physical exams, neurologic evaluations, complete blood counts, and other laboratory and safety assessments will be performed approximately every 21-days while receiving treatment. Tumor assessments are to be performed approximately every 42 ± 7 days while remaining on study. The study is estimated to last approximately 20 months.
