A Study Comparing Niraparib With Temozolomide in Adult Participants With Newly-diagnosed, MGMT Unmethylated Glioblastoma

The goal of this Phase 3 clinical trial is to compare the efficacy of niraparib versus temozolomide (TMZ) in adult participants with newly-diagnosed, MGMT unmethylated glioblastoma multiforme (GBM). The main question it aims to answer is: Does niraparib improve overall survival (OS) compared to TMZ? Participants will be randomly assigned to one of two treatment arms: niraparib or TMZ. * study drug (Niraparib) or * comparator drug (Temozolomide - which is the standard approved treatment for MGMT unmethylated glioblastoma). The study medication will be taken daily while receiving standard of care radiation therapy (RT) for 6-7 weeks. Participants may continue to take the niraparib or TMZ adjuvantly as long as the cancer does not get worse or completion of 6 cycles of treatment (TMZ). A total of 450 participants will be enrolled in the study. Participants' tasks will include: * Complete study visits as scheduled * Complete a diary to record study medication

Stereotactic Radiosurgery (SRS) Dose-Escalation Study for Brain Metastasis

SRS dose escalation for brain metastases in radiation-naïve patients will establish true tolerable doses, which may exceed the current standard doses. This may lead to an improvement in local control, patient survival, and/or quality-of life.

The RECMAP-study: Resection With or Without Intraoperative Mapping for Recurrent Glioblastoma

Resection of glioblastoma in or near functional brain tissue is challenging because of the proximity of important structures to the tumor site. To pursue maximal resection in a safe manner, mapping methods have been developed to test for motor and language function during the operation. Previous evidence suggests that these techniques are beneficial for maximum safe resection in newly diagnosed grade 2-4 astrocytoma, grade 2-3 oligodendroglioma, and recently, glioblastoma. However, their effects in recurrent glioblastoma are still poorly understood. The aim of this study, therefore, is to compare the effects of awake mapping and asleep mapping with no mapping in resections for recurrent glioblastoma. This study is an international, multicenter, prospective 3-arm cohort study of observational nature. Recurrent glioblastoma patients will be operated with mapping or no mapping techniques with a 1:1 ratio. Primary endpoints are: 1) proportion of patients with NIHSS (National Institute of Health Stroke Scale) deterioration at 6 weeks, 3 months, and 6 months after surgery and 2) residual tumor volume of the contrast-enhancing and non-contrast-enhancing part as assessed by a neuroradiologist on postoperative contrast MRI scans. Secondary endpoints are: 1) overall survival (OS), 2) progression-free survival (PFS), 4) health-related quality of life (HRQoL) at 6 weeks, 3 months, and 6 months after surgery, and 4) frequency and severity of Serious Adverse Events (SAEs) in each arm. Estimated total duration of the study is 5 years. Patient inclusion is 4 years, follow-up is 1 year. The study will be carried out by the centers affiliated with the European and North American Consortium and Registry for Intraoperative Mapping (ENCRAM).

5-Aminolevulinic Acid (5-ALA) Gliolan®: Usage Increase Proposal for Neurosurgical Procedures in High-Grade Gliomas

The goal of this observational study is to evaluate disease-free survival (DFS) in patients with malignant gliomas undergoing neurosurgical procedures using 5-aminolevulinic acid (5-ALA)-based photodynamic therapy

The Cohort for Patient-reported Outcomes, Imaging and Trial Inclusion in Metastatic BRAin Disease (COIMBRA)

The incidence of brain metastases is expected to increase because of better treatments of primary tumours. Novel diagnostic and therapeutic techniques are continuously being developed, all of which need thorough evaluation before they can be implemented in clinical routine. Randomized Controlled Trials are the gold standard to do so, but they have shown many challenges, especially when applied in a cancer setting. .The 'cohort multiple Randomized Controlled Trial (cmRCT)' design is a promising design for multiple (simultaneous) randomized evaluations of experimental interventions, with potential for increased recruitment, comparability and long-term outcomes as a standard. This design will speed up the process of translating treatment innovations to the daily clinic.
