PSMA is highly expressed on the cell surface of the microvasculature of several solid tumors, including glioma. This makes it a potentially imaging target for the detection and grading of gliomas. This pilot study was designed to evaluate the diagnostic performance of 68Ga-P16-093, a novel radiopharmaceutical targeting PSMA, which was compared with MRI in the same group of glioma patients.
Based on the high expression of specific receptors on the surface of diseased tissues and neovascularization, noninvasive targeted molecular imaging can be used to visualize lesions in vitro by combining specific ligands labeled with short half-life isotopes. In this study, a novel dual-target imaging agent 68Ga-RM26-RGD was used for clinical study of tumor PET/CT imaging to further verify its clinical application value.
This clinical trial studies the use of 7-Tesla (7T) magnetic resonance imaging (MRI) in detecting melanoma that has spread to the brain (melanoma brain metastases). The standard MRI brain imaging is done on 3T or similar MRI machine, but the 7T MRI machine has a larger magnet which has been shown to have superior resolution of the brain and of non-cancerous brain lesions. Diagnostic procedures such as 7T MRI may help find and diagnose melanoma brain metastases earlier than standard 3T MRI.
Bevacizumab can be an effective treatment for individuals with NF2 and improve different nerve functions (like hearing, tinnitus or balance problems) and the quality of life of NF2 patients. However, bevacizumab is not effective in all patients or all tumors, at the cost of moderate toxicity and considerable financial burden. Therefore, this observational study will validate an imaging biomarker method to predict bevacizumab efficacy in order to avoid adverse effects and high costs in non-responders to bevacizumab treatment. Patients will undergo standard-of-care treatment with the sole addition of a pre-treatment 89Zr-Bevacizumab...
There is no consensus in the literature on the best way to treat cystic lesions of the pituitary area. Patients who are symptomatic from these tumours are rare. The cystic form of tumours present special challenges since traditional treatment modalities (surgery and/or external radiation) are often not able to completely remove or treat the cyst wall without major morbidity or even mortality. There is no 'best practice' for the treatment of cystic tumours per se. Treatments available to patients with cystic sellar/parasellar tumours include conservative management using a 'wait and scan' approach, cyst drainage, and cyst removal...
GSK-3β is a potentially important therapeutic target in human malignancies. The Actuate 1801 Phase 1/2 study is designed to evaluate the safety and efficacy of 9-ING-41, a potent GSK-3β inhibitor, as a single agent and in combination with cytotoxic agents, in patients with refractory cancers.
This is a phase 0/I exploratory study. Patients at first or second recurrence of glioblastoma will be enrolled. The study will be divided into two cohorts: Cohort A (safety cohort) and Cohort B (surgical patient cohort). Cohort A: Eligible patients will be sequentially enrolled to receive intravenous AB154 combined with AB122 (N=6). AB154 will be given at a dose of 10 mg/kg and AB122 will be given at a dose of 240 mg (flat). Cohort B: Expansion surgical cohort. The purpose of cohort B is to provide an additional safety evaluation of AB154 + AB122 as well as tissue and blood for exploratory ancillary studies investigating...
This is a Phase I clinical trial evaluating abemaciclib (LY2835219), an inhibitor of cyclin dependent-kinases 4 and 6 (Cdk 4/6) in children and young adults with newly diagnosed diffuse intrinsic pontine glioma (DIPG) (Stratum A) and in relapsed/refractory/progressive malignant brain (Grade III/IV, including DIPG; MBT) and solid tumor (ST) patients (Stratum B).
This phase II trial studies how well abemaciclib works in treating patients with digestive system neuroendocrine tumors that have spread to other places in the body, do not respond to treatment, and cannot be removed by surgery. Abemaciclib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.
Background: Diffuse midline gliomas are the most aggressive brain tumors of childhood and young adults. Most people with these tumors survive less than 2 years. Researchers want to see if an anticancer drug (abemaciclib) can help. Objective: To see if researchers can measure how much abemaciclib is in a person's brain tumor and brain fluid after they take the drug for a few days. Eligibility: People aged 18 to 39 with recurrent high-grade glioma or diffuse midline glioma. Design: Participants will be screened with: Medical history Physical exam Blood and urine tests ...
