Active clinical trials for "Brain Neoplasms"

This study will consist of a Phase 1b and Phase 2 portion. The Phase 1b portion will enroll first followed by the Phase 2 portion. Each cycle of treatment = 28 days. Subjects will receive alectinib twice daily. Those in the Phase 1b portion will receive alectinib alone. Those in Phase 2 Arm A will receive alectinib alone. Those in Phase 2, Arm B will receive SRS + alectinib. A maximum of 25 cycles (2 years) of alectinib may be administered on study.

The purpose of this study is to determine if the study drug, patritumab deruxtecan (HER3-DXd), can be measured in brain tumor tissue after recieving one dose of patritumab deruxtecan before surgery.

This is a prospective multicenter clinical study. This study aims to construct an auxiliary decision-making system for lung cancer immunotherapy combined with radiotherapy by fusing three modes of imagomics, clinicopathological features, and molecular pathological features.

This prospective imaging study is evaluating the feasibility of using the Halcyon 4.0 radiotherapy system for radiation therapy planning in patients with cancer. The Halcyon 4.0 system has been engineered to decrease the image acquisition time and the radiation exposure, but the system has not yet been clinically validated for use in radiation planning. This pilot study will evaluate images obtained on the Halcyon 4.0 system to assess if the quality is sufficient for radiation treatment plan construction.

A glioma is a primary brain tumor in adults that is characterized by a highly variable, but overall poor survival. The optimal timing of treatment is in part determined by the expected biological behavior of the tumor. At present the expected biological behavior, determined by the tumor genotype, can only be determined by tissue analysis, which requires brain surgery. Non-invasive and improved diagnostic methods are sought to obtain insight into the molecular profile of the tumor and the expected biological behavior to avoid surgery performed solely for diagnostic purposes. Vascularization is an important aspect of the biological behavior of a primary brain tumor. Tumor vascularization characteristics can be assessed by Magnetic Resonance Imaging (MRI), but with the currently available technology this can only be achieved with unacceptably long scan times. In this proposal, the investigators will develop and optimize a novel MRI protocol to gather a large set of quantitative vascularization parameters within an acceptable scan time. The hypothesis is that from such a 'vascular signature' the tumor genotype can be inferred by means of machine learning.

This is a prospective, single-center observational clinical study aimed at the efficacy and safety of radiotherapy combined with PD-1 inhibitors and chemotherapy in the treatment of Chinese patients with symptomatic NSCLC with brain metastases.

This phase I/II trial will investigate the use of the novel oral IRAK-4 inhibitor CA-4948 in combination with pembrolizumab therapy following stereotactic radiosurgery in patients with melanoma brain metastases (MBM). The investigators hypothesize that the addition of CA-4948 will reduce the rate of distant intracranial failure and reduce the need for subsequent radiation therapy. The investigators also propose that it will have a significant reduction in radiation necrosis and improve patient-reported symptoms and quality of life. This trial represents the first time an oral IRAK-4 inhibitor has been used in combination with aPD1 therapy in MBM and will yield valuable insight into its synergistic potential both in MBM and additional sites of metastases.

Insomnia is the most common sleep disorder in patients with primary brain tumors. In the past, 21.5% to 59.2% of patients with primary brain tumors suffer from insomnia symptoms. In addition to hypnotics, nonpharmacological interventions for insomnia in patients with brain tumors are still lacking. When using hypnotics may cause daytime sleepiness, cognitive impairment, and increase the risk of cancer, seeking an effective intervention is of clinical importance. Sensorimotor rhythm neurofeedback therapy has been shown to improve insomnia in different populations. However, its effect on insomnia has not been explored in patients with brain tumors. We, therefore, aim to investigate the feasibility and effect of sensorimotor rhythm neurofeedback in improving insomnia in patients with benign brain tumors after surgery and to examine the correlation between the degree of insomnia improvement and quality of life changes after receiving sensorimotor rhythm neurofeedback.

The investigators will collect biosamples of patient blood and tumour tissue for further immunological analysis of blood cell subpopulations, immunosupressive factors concentration, HLA expression an lymphocytes and tumour tissue, and and cancer testis antigenes expression on tumour cells, as well as clinical data on patient's stage, therapy, response and demographics. Possible prognostic and predictive dynamic biomarkers will be discovered for individualisation of treatment strategies

The goal of this observational study is to characterize the circulating leukocyte profile and the immune T cells distribution within the tumor in patients with malignant brain tumors and to correlate these findings with the oncological outcome. Participants will be subjected to blood sampling before surgery and for 12 months of follow-up. Additional sampling and analysis will be performed on tumor samples.
